专题06 航天航空
Passage 1
（2021·湖南衡阳市·高三二模） On February 22, 2021, cancer survivor Hayley Areeneaux was selected to be one of four crew members of the SpaceX Inspiration4 — the world’s first civilian astronaut mission. The 29-year-old will make history as the youngest American — and the first with a false limb — to travel to space.
Hayley’s space dreams began two decades ago, following a visit to the NASA Johnson Space Center in Houston, Texas. However, the young girl’s dreams were derailed a year later when she was diagnosed with osteosarcoma — a type of bone cancer.
Fortunately, the fatal disease had been caught early and the experts at St. Jude’s Children’s Research Hospital in Memphis were able to reduce its spread through chemotherapy and by replacing the diseased bones with metal rods (杆) in her left leg. Arceneaux said she never thought she would be able to go to space. But when the call came “out of the blue” from Jared Isaacman, CEO and founder of Shift4 Payments, asking her if she would like to go to space, she said without hesitation, “Yes, yes, absolutely!”
Isaacman had always intended to go to space. Hence when SpaceX announced the world’s first all-commercial astronaut mission, the 37-year-old billionaire, instantly booked the available four seats. The flying enthusiast announced that he would donate three seats to members of the general public. Hayley, the first crew member to be announced, will represent the pillar (支柱) of “hope” — a nod to her survival of cancer and frontline work as a physician at St. Jude. The remaining passengers, representing the pillars of “generosity” and “prosperity”, will be chosen randomly to raise $200 million for St. Jude, which treats children at no charge.
Before the mission launch later this year, the crew will undergo intense training. The mission, which will orbit Earth every 90 minutes, will be carefully monitored by SpaceX mission control scientists from Earth. Upon the mission’s completion, the Dragon will reenter Earth’s atmosphere for a soft water landing off the coast of Florida.

C．To inspire interests in space travel. D．To seek help for disabled children.

Passage 2
（2021·上海高三模拟） It looked just like another aircraft from the outside. The pilot told his young passengers that it was built in 1964, a Boeing KC-135 refuelling tanker, based on the 707. But appearances were deceptive, and the 13 students from Europe and USA who boarded the aircraft were in for the flight of their lives.
For 12 months, science students from across the continents had competed to win a place on the flight at the invitation of the European Space Agency. The challenge had been to suggest imaginative experiments to be conducted in weightless conditions.
For the next two hours the Boeings flight resembled that of an enormous bird which had lost its reason, shooting upwards towards the heavens before moving down towards Earth. The intention was to achieve weightlessness for a few seconds.
The aircraft took off smoothly enough, but any feelings that I and the young scientists had that we were on anything like a scheduled passenger service were quickly dismissed when the pilot put the plane into a 45-degree climb which lasted around 20 seconds. Then the engines cut out and we became weightless. Everything became confused, and left or right, up or down no longer had any meaning. After ten seconds of free-fall descent (下降) the pilot pulled aircraft out of its nosedive. The return of gravity was less immediate than its loss, but it was still sudden enough to ensure that some students came down with a bump.
Each time the pilot cut the engines and we became weightless, a new team conducted its experiment. First it was the Dutch, who wanted to discover why cats always land on their feet. Then it was the German team, who conducted a successful experiment on a traditional building method to see if it could be used for building a future space station. The Americans had an idea to create solar sails that could be used by satellites.
After two hours of going up and down in the plane doing experiments, the dominant feeling was one of excitement rather than sickness. Most of the students thought it was an unforgettable experience and one that would be keen to repeat.
5．What did the pilot do with the plane?
A．He climbed and then made the plane fall slowly.
B．He climbed and then made the plane turn over.
C．He quickly climbed and then stopped the engines.
D．He took off normally and then cut the engines for 20 seconds.
6．What was the point of being weightless?
A．To show the judges of the competition what they could do.
B．To prepare the young scientists for future work in space.
C．To see what conditions are like in space.
D．To allow the teams to try out their ideas.
7．The pronoun “it” (in the last paragraph) refers to ________.
A．the excitement B．the trip
C．the opportunity D．the plane
8．The passage is intended to ________.
A．report on a new scientific technique
B．encourage young people to take science
C．show scientists what young people can do
D．describe the outcome of a scientific competition

Passage 3
（2021·全国高三模拟） Beatrice Finkelstein, as chief of the Food Technology Section of the Life Support Systems Laboratory at Wright Patterson Air Force Base, bore responsibility for managing the nutritional needs of the astronauts. Her work in the field of space feeding was important in developing the equipment and techniques used in early space flight. Few, if any, female contributors played as important a role as she did during the early years of the U. S. crewed space program, and she deserves to be better remembered.
Finkelstein’s value to America’s space tasks went well beyond her technical contributions. She was frequently described in the popular press at the time as “the Nutritionist to the Astronauts”, as well as the proprietor or of “Bea’s Diner”, a restaurant designed to appeal to the public as a very friendly place.
In her role as nutritionist for the early space program, Finkelstein grew to know the astronauts well, as she communicated with them frequently. At times, she would step beyond her formal role as nutritionist, providing emotional and psychological support to the astronauts. On many occasions, she was one of the last people the astronauts communicated with before launch (发射), and there’s a lot of evidence that shows her friendship was a source of comfort during the stressful pre-launch activities.
The image of nutritionist Beatrice Finkelstein showed that the agencies that insured NASA’s successful space flights were staffed by smart women as well as smart men. Her role in America’s success in conquering space in the technical field of space feeding served as an example of the role women could and did play in the early space program.
9．Why does Beatrice Finkelstein deserve to be remembered?
A．She was a really great astronaut.
B．Her astronaut team made significant achievements.
C．She bore responsibility for early space flight.
D．Her feeding work was vital in early space flight.
10．What does the underlined word “proprietor” in Paragraph 2 mean?
A．Tutor. B．Editor. C．Owner. D．Engineer.
11．What can we infer about Beatrice Finkelstein from Paragraph 3?
A．She was also a psychologist.
B．She relieved astronauts’ pressure.
C．She communicated with astronauts after launch.
D．She cooked much nutritious food for astronauts.
12．What is the best title for the text?
A．One Special Nutritionist B．A Great Space Astronaut
C．The First Woman Astronaut D．The Most Popular Nutritionist

Passage 4
（2021·浙江省杭州第二中学高三模拟） "That's awesome”, said NASA astronaut Kjell Lindgren, after he ate a piece of red lettuce （萬苣）that was grown in a special box. "Tastes good," agreed US astronaut Scott Kelly, who is spending one year at the research station. "kind of like arugula （芝麻菜），” Kelly added, and then used small bottles to spread olive oil and vinegar on his leaf, much as one might spread ketchup on a hot dog.
NASA says that if space explorers can grow their own food while they are away from the Earth they would be more likely to survive the deep space exploration, which can last months or even years. With no way to resupply a spacecraft making a long journey to and from Mars, the ability to grow food during the trip will be key to survive. "Having the ability for us to grow our own food is a big step in that direction.” Kelly said.
Ray Wheeler, NASA's lead scientist for advanced life support activities at Kennedy Space Center in Florida, also said fresh foods that contain antioxidants, such as tomatoes, blueberries and red lettuce, “could have a positive impact on people's moods and also could provide some protection against radiation in space.”
The red romaine lettuce was grown in a special plant-growing box called a Veggie unit, and was flown to space. The seeds are contained in rooting pillows, which come complete with soil and fertilizer. Since water cannot be poured in space, a special irrigation system delivers moisture to the plant pillows from below.
The seeds were "activated" by Kelly on July 8 and grew for 33 days. On Monday, Lindgren used tongs （夹子）to harvest the lettuce from its growing box, before attaching the leaves carefully to a tray. He cleaned them with food-safe bag and shared with other four members.
A previous crop of lettuce was grown in space last year but was not eaten by astronauts. Instead, it underwent-and passed-food safety tests back on Earth.
13．How did Scott prepare the space-grown lettuce?
A．He cooked it in a special box. B．He mixed it with some arugula.
C．He spread a little bit ketchup on it. D．He put olive oil and vinegar on it.
14．What does the underlined part “that direction”refer to?
A．The journey to and from Mars. B．The way to grow food.
C．The building of a research station. D．The ability of flying in space.
15．Which of the following may Ray Wheeler agree to?
A．The lettuce is a great step enabling human to travel to Mars.
B．Humans won't be able to arrive at Mars without the lettuce.
C．Tomatoes are obviously better than blueberries in size.
D．Radiation wouldn,t be harmful if people ate some lettuce.
16．What is difficult in growing lettuce in space?
A．There is no enough growing area. B．It is very hard to send up the seeds.
C．A special way of watering is needed. D．It does not need soil or the fertilizer.

Passage 5
（2021·青龙满族自治县第一中学高三模拟） The lander carrying China’s first Mars rover successfully touched down on the red planet early Saturday morning Beijing Time. It is the first time China has landed a probe on a planet other than Earth.
Tianwen-1, consisting of an orbiter, a lander and a rover, was launched from the Wenchang Spacecraft Launch Site on the coast of southern China’s island province of Hainan on July 23, 2020. This is the first step in China’s planetary exploration of the solar system, with the purpose of completing orbiting, landing and roving on the red planet in one mission.
The name Tianwen, meaning “questions to Heaven”, comes from a poem written by the ancient Chinese poet Qu Yuan (about 340-278 BC). China’s first Mars rover is named Zhurong after the god of fire in ancient Chinese mythology, which echoes with the Chinese name of the red planet: Huoxing (the planet of fire).
Tianwen-1 was launched via a Long March-5 rocket, China’s largest launch vehicle. Tianwen-1 has been traveling in space for nearly 10 months. It has carried out four orbital corrections and a deep-space maneuver. It had flown 475 million km and was 192 million km from Earth when it reached Mars orbit.
The craft’s plummet through the Martian atmosphere, lasting about nine minutes, was extremely complicated with no ground control, and had to be performed by the spacecraft autonomously.
“Such a challenging attempt is characterized by a succession of complex activities that must be conducted completely by the spacecraft within a very short period of time,” said Geng Yan, an official with the Lunar Exploration and Space Program Center of the CNSA．“What added to the difficulties was that we don’t know much about the Martian atmosphere, which brought a lot of uncertainties to the mission. Each step had only one chance, and the actions were closely linked. If there had been any flaw, the landing would have failed.”
17．What is the mission of Tianwen-1?
A．To record the wind speed on Mars. B．To explore the atmosphere of Mars.
C．To search for aliens in the solar system. D．To accomplish three major tasks on Mars.
18．What is paragraph 3 mainly about?
A．The introduction of the poet Qu Yuan. B．The reasons for the craft landing on Mars.
C．The origin of two names Tianwen and Zhurong. D．The importance of ancient Chinese mythology.
19．What do the numbers in paragraph 4 mainly indicate?
A．The huge task of Tianwen-1. B．The surroundings of the Mars orbit.
C．The expense of traveling in space. D．The size of the Long March-5 rocket.
20．What can we know from Geng Yan’s words?
A．China’s attempt to explore Mars is successful.
B．Landing on Mars is a very challenging move.
C．People are enthusiastic about exploring the universe.
D．Tianwen-1 is essential to China’s space station program.

Passage 6
（2021·北京师范大学天津附属中学高三三模） China landed a spacecraft on Mars for the first time last Saturday. This makes China the first country to make a successful landing on Mars on its first mission to Mars. China's Zhurong rover （探测车），named after a traditional Chinese fire god, has touched down on the martian surface, the China National Space Administration confirmed on the morning of Saturday, May 15,
The rover is part of the Tian wen-1 mission, which consists of an orbiter, a probe, and a lander. The mission was launched in summer last year, and took seven months to complete its journey to the red planet. It arrived at Mars in February this year, and since then the spacecraft has been performing operations such as capturing images of Mars.
Believe it or not, traveling to Mars is actually the easy part of such a mission. The truly hard part is landing on the planet's surface, as landers must contend with factors like the planet's thin atmosphere, its variable dust storms, and a communication delay between Mars and Earth. This delay makes it impossible for people in mission control on Earth to control a craft in real time as it approaches the planet, so the landing must be performed autonomously.
To slow its speed as the lander approached the surface, it used both a parachute （降落伞）and a retrorocket (减速火箭）in its own "seven minutes of terror" as it moved through the atmosphere. It then landed in the Utopia Planitia area, a large impact basin, part of which was exploded by NASA's Viking 2 lander in the 1970s.
According to China's slate news agency Xinhua, President Xi Jinping said he was sending "warm congratulations and sincere greetings to all members who have participated in the Mars exploration mission.'
The rover will now begin its three- month mission to explore the Utopia Planitia area, where it will be searching for surface and subsurface ice. The mission will involve both the rover and the orbiter working in concert to create a map of water ice, with the orbiter focusing on the planet's polar regions.
21．Which of the following statements is TRUE according to the passage?
A．The Tianwen-1 mission includes four space missions.
B．Zhurong was known as a great astronomer in ancient China.
C．The spacecraft has carried out a series of experiments in advance.
D．China achieved success in landing on Mars creating a new record.
22．What should be carefully considered on landing on Mars?
a. Mars's atmosphere. b. Mars's bad weather
c. The landing instructions. d. The communication delay.
A．abc B．bed C．abd D．abcd
23．What does the author imply in Paragraph 4?
A．The landing way is quite different. B．The landing process is full of danger.
C．The landing site is unknown to NASA． D．The landing time is calculate precisely.
24．Which of the following missions will be launched in three months?
A．The analysis of ice samples.
B．The mapping of the Mars's polar regions.
C．The exploration of the Utopia Planitia area.
D．The collection of surface and subsurface ice.
25．Which column does the passage come from?
A．Space B．Fiction C．Medical D．Nature

Passage 7
（2021·广东广州市·高三二模） When the Chinese spacecraft Chang’e-5 returned to Earth on December 17, 2020, it brought back something not seen on our planet since the 1970s: moon rock samples. This precious cargo, collected by Chang’e-5’s robotic research vehicle in the northwest region of the lunar near side, is now being studied by scientists in Beijing. The success of the latest Chinese space mission also showcased technology that may be used in future years to create human settlements on Earth’s near neighbor.
The returned lunar samples will “absolutely add new knowledge of the history of the moon, particularly its volcanoes,” says Xiao Long, a planetary scientist at China University of Geosciences. The rocks sent back by Chang’e-5 “will ask us to rethink about why and how the moon’s volcanic history lasted this long,” he says.
The Chang’e-5 mission was more than just a trip to collect moon rocks. It was also the latest stage of a long, planned sequence of robotic lunar explorations by China that have grown ever more scientifically advanced.
The program began with the 2007 launch of Chang’e-1 and Chang’e-2 three years later. These craft circled the moon collecting data used to help guide Chang’e-3 and Chang’e-4, the first Chinese spacecraft to land on the moon surface, and to direct their robotic vehicles. The robot on Chang’e-5 was able to collect rock and soil samples and return them to Earth. In the near future, an identical spacecraft called Chang’e-6 will attempt a sample-return mission from the moon’s south pole—an area of intense scientific interest-given the large amount of water ice present.
The more advanced Chang’e-7 and Chang’e-8 spacecraft are also planned to land near the south pole to carry out analysis of the region and test new technologies, including detecting and obtaining materials that could be useful to future human explorers, such as water and hydrogen, and testing 3D printing on the lunar surface.
The long-term aim of the Chang’s program is to establish an International Lunar Research Station around 2030 to support robotic and, eventually, crewed missions.
26．What is paragraph 2 mainly about?
A．The moon’s recent volcanic activities. B．The significance of the moon rock samples.
C．New knowledge of the history of the moon. D．Further studies of the returned lunar samples.
27．What distinguishes the mission of Chang’e-6 from that of Chang’e-5?
A．The technology they use. B．The time they spend on the moon.
C．The specific locations they explore. D．The amount of material they bring back.
28．Chang’e-7 and Chang’e-8 space missions are mainly intended to ________.
A．transport researchers to the moon station
B．build up an International Lunar Research Station
C．collect data necessary to guide moon-landing spacecraft
D．find and test resources and means to support living on the moon
29．Which of the following best summarizes the Chang’s space program?
A．A project to study the surface of the moon.
B．A plan to improve human settlements on the moon.
C．A set of experiments to test the possibility of manned spacecraft.
D．A series of increasingly challenging scientific lunar explorations.


Passage 8
（2021·重庆八中） China successfully sent the 52nd and 53rd satellites of its domestically developed BeiDou Navigation Satellite System (BDS)—the last two medium Earth orbit (MEO) satellites for the BDS-3 constellation (星座)—into space on Monday, marking the completion of the global navigation system’s core constellation deployment (部署) and this year’s BDS satellite launch campaign.
Launched from Xichang Satellite Launch Center, Sichuan Province, on board a Long March-3B carrier rocket with an Expedition-1 upper stage, the two satellites were injected into planned orbits after more than three hours’ flight.
Since the first BDS-3 satellite was launched on November 5, 2017, China has conducted 18 BDS satellite launch missions, successfully sending 30 into their planned orbit, setting a national record for highest mission frequency and success rate.
In-orbit tests will be carried out before the two MEO satellites are commissioned (正式委托). By then the core constellation for the Chinese global navigation satellite system will be successfully completed.
Wang Ping, chief designer of the BDS-3 system, said that the hybrid constellation design, in which three groups of satellites—the Inclined Geo Synchronous Orbit (IGSO), MEO and geosynchronous Earth orbit (GEO)—work in concert in different orbits, was an exclusive BDS innovation and a world first. “Existing global navigation satellite systems, such as the US GPS and Russia’s GLONASS, only have a MEO satellite constellation,” said Wang.
The MEO satellites, in orbit 20,000 kilometers above Earth, are a special type of satellite providing global service, while the IGSO and GEO satellites, in an orbit 360,000 kilometers above Earth, mainly enhance regional service quality, according to Wang. That explained why completion of the MEO constellation was significant, marking the completion of the core network for BDS-3, meaning a stable BDS-3 global coverage without weak points has been carried out.
Feedback shows that the BDS service quality was already comparable to GPS since the end of 2018, and after completing BDS-3, “We will be as good as any GNSS.” Wang said.
30．How many BDS satellites were sent into their planned orbit successfully?
A．3. B．18. C．30. D．36.
31．What’s the advantage of BDS compared with GPS and GLONASS?
A．The diverse functions.
B．The excellent service quality.
C．The lower cost of designing it.
D．The ability to work in different orbits.
32．Why are the MEO satellites important?
A．They enhance regional service quality.
B．They can be put into use immediately.
C．They can enter farther orbits.
D．They can serve the world.
33．What may be the best title for the text?
A．China Becomes the First Country to Launch a MEO Satellite
B．The Core Constellation of BDS-3 Completes Deployment
C．The BDS-3 System Has Benefited Many Countries
D．Exploring Space Is Very Important to the World

Passage 9
（2021·石门县第一中学） Chinese President Xi Jinping announced on July 31 that China's BeiDou Navigation Satellite System (BDS) has been completed and has started providing full-scale global services that day.
In the 1990s, Chinese government approved and began research and development of a space-based navigation and positioning system aimed at easing the country's heavy dependence on foreign networks. The system is called "BeiDou". It has planned a three-step strategy for developing the BDS.
The construction of BDS-1, the first step of the strategy, started in 1994 and was completed in 2000. The BDS-2 system started construction in 2004. By 2012,a total of 14 satellites had been launched to complete the deployment(部署)．In November 2017, China launched the first two satellites for the BDS-3 system, which started construction in 2009, and officially expanded its regional navigation system into a global network.
In late June, the final satellite to complete BeiDou's third-generation network was lifted by a Long March 3B carrier rocket. After in-orbit tests over the past month, the satellite recently started its formal operations.
Since 2000, 59 BeiDou satellites, including the first four experimental ones, have been launched from Xichang on 44 Long March 3-series rockets, with some of them having retired.
BeiDou began providing services for civilian users in China and other parts of the Asia-Pacific region in December 2012. At the end of 2018, it started providing basic global services. BeiDou offers accurate positioning, navigation and timing, as well as short messaging communication. The services are used in various fields.
It offers an alternative to Russia's GLONASS and the European Union's Galileo system, as well as the United States' GPS.
The operating of BeiDou's full-scale global services is a significant milestone in China's efforts to boost science and technology and strengthen its space industry. The move is a major contribution to the global public-service infrastructure (基础设施) as well as a remarkable strategic achievement of socialism with Chinese characteristics in the new era.
34．How many navigation systems are mentioned in this passage?
A．2. B．3 C．4 D．5
35．Which is NOT the function of the BDS?
A．Offering accurate timing.

B．One small step for China, a giant leap for mankind.
C．China's BeiDou System begins its full-scale global services.
D．The development of the BeiDou Navigation Satellite System.

Passage 10
（2021·辽宁高二期末） Around 50 Mars missions have been launched globally since 1960. Yet more than half of them have failed to reach the planet. So after China’s Mars probe—Tianwen-1, was launched on July 23, Thursday last year, there was an anxious wait to learn its fate.
The news that the craft carrying exploration rover Zhurong landed safely on the surface of the planet on Saturday has therefore been met with both relief and celebration in the country.
That the landing was carried out exactly as planned has made China the latest member, after the United States and Russia, of the club of the world’s pioneering Martin explorers, and shows the reliability of the relevant technologies that China has developed on its own. Though the first Mars mission of the country, it was a brave undertaking: to complete orbiting, landing and roving in one single mission.
It is that can-do spirit of self-reliance（自力更生） that has played a key role in China’s scientific and technological development in recent decades despite some foreign countries’ attempts to prevent its progress. China made its early breakthroughs in rocket and space technologies with its own scientists, engineers and scientific workers starting from the 1960s under very difficult conditions when the country remained largely a backward agricultural country and faced foreign blocks of technology and materials.
However, the country has made the most of what it had over the past more than six decades, making continuous efforts to go ahead in the aerospace（航天）cause. Thanks to the hard work and even sacrifices of generations of scientific workers, China has laid a solid foundation for the fast development of its aerospace industry, and has achieved one milestone after another in its space endeavors.
In the human space odyssey, China, with enthusiasm, diligence and willingness to cooperate, will help promote humankind to travel faster and farther.
38．What’s the purpose of this text?
A．To introduce a kind of astronomical phenomenon.
B．To recall the development of China’s aerospace exploration.
C．To boost Chinese people’s confidence in aerospace exploration.
D．To state the difficulties China faced in aerospace development.
39．How does the author feel about the development of China’s aerospace industry?
A．Confused. B．Proud.
C．Worried. D．Astonished.
40．What can we learn from the text?
A．More than half of Mars missions have succeeded since 1960.
B．The exploration rover Zhurong landed on Mars on July, 25 th .
C．The mission of Tianwen-1 was to complete orbiting and landing.

Passage 11
（2021·浙江高二期末） Bored with your life? Dreaming of something different? I always wonder what life would be like 400 km above my head. That's where the International Space Station orbits the earth, with six astronauts living and working on board, for months at a time.
How do they sleep? They spend the night floating in a sleeping bag inside a small cubicle (小隔间) on the ceiling. American astronaut Sunita Williams explains, “It's like a little phone booth, but it's pretty comfortable and it doesn't matter if I turn over and sleep upside down. I don't have any sensation (感觉) in my head that tells me I'm upside down.”
Brushing your teeth in a place where you can't have a tap or a sink can be a challenge. Can you imagine the mess that running water would make in zero gravity? Canadian astronaut Chris Hadfield uses a straw to put a big blob of water from a sealed bag onto an ordinary toothbrush and adds a little toothpaste which he has to swallow when he's done.
Daily exercise is essential. The lack of gravity makes bones more fragile and muscles lose strength — so astronauts are encouraged to work out for at least two hours a day.
The role of astronauts in the International Space Station is to act as lab technicians for scientists back on earth. So they spend their time maintaining their environment and performing and monitoring experiments in a confined space about the size of a Boeing 747. Almost every task is carefully planned by mission control — although most astronauts spend their first days losing things until they get used to sticking everything they use to the walls with Velcro, duct tape (强力胶带) or clips (夹子)．
One of their most valued perks (额外待遇) is the view from “the office”, dominated by that gigantic blue ball down there, sitting in the darkness of space. Wow! Absolutely breathtaking!
42．When they sleep upside down, the astronauts will not get dizzy because ________.
A．they don't feel it
B．they sleep in the daytime
C．they sleep in special sleeping bags
D．they are trained to adapt to the conditions of weightlessness
43．What parts become weak if astronauts don't exercise?
A．Their teeth and bones.
B．Their brains and bones.
C．Their bones and muscles.
D．Their teeth and muscles.
44．What is the passage mainly about?
A．The Problems We Met in Space.
B．Living and Working in Space.
C．How to Become an Astronaut.
D．The International Space Station.

Passage 12
（2021·广西百色市·高二期末） Over the years, NASA has successfully sent several rovers (飞行器) to Mars. While the science laboratories continue to provide important information on the Red Planet, they keep the space exploration rovers staying close to the original landing place.To get a more comprehensive (详尽的) view of Mars, the US Space Agency plans to make a small test helicopter with the Mars 2020 Rover, which will be sent off in July 2020.
The football-sized “marscopter” weighs about four pounds. It can fly at about ten times the speed of helicopters on Earth. The light weight and fast speed are important for the helicopter to be able to fly in the thin Mars atmosphere, which is about just one percent of that of Earth. “To make it fly in that thin Mars atmosphere, we had to make everything ready, and make it as light as possible while being as strong and powerful as it can possibly be. “Mimi Aung, Mars helicopter project manager, said in a meeting.
Upon landing on the Red Planet, the Mars 2020 Rover will find a proper location to send of the helicopter. The helicopter will start with a short climb, no higher than 10 feet, and hover (盘旋) for just 30 seconds before landing back on the Mars surface. If all goes well, five more flights of longer distances, for 90 seconds each, will be conducted over the next 30 days. The short journeys will be recorded by a small camera and sent back to the scientists on Earth.
If the plan goes on well, the first helicopter to fly in another world, will open up a whole new way to explore Mars. The Mars helicopter's first flight will be a great invention. For those of us whose research is about flight, that would be a wonderful, historic moment.

C．To live in the thin Mars atmosphere D．To send back records to scientists

Passage 13
（2021·湖北高二期末） A Chinese space mining company has designed a robot that can capture waste material left behind by spacecraft in outer space with a big net.
The state-run Xinhua news agency recently reported that the robot launched on the government's Long March 6 rocket along with several satellites. The robot will also investigate deep space to observe small objects in the universe. The 30-kilogram robot, called NEO-01 , was developed by Origin Space. Pounded in 2019 and based in the southern Chinese tech hub(技术中心)Shenzhen, Origin Space has been devoted to exploring and using space resources, according to the company. The company says the robot will lead the way for future technologies capable of mining on asteroids(小行星).
The world's first asteroid mining company, Planetary Resources, was established in 2009. Since then, more than 12 businesses around the world have entered the industry, including 3D Systems of the United States and Japan's Astroscale. Astroscale's technology uses magnets (磁铁)to gather up space waste. But a report on the Origin Space website says NEO-01 will use a net to capture waste and then bum it. Thousands of satellites have been launched worldwide. As they are used too long, many end up as waste and put other operating satellites at risk.
Su Meng is the founder of Origin Space. He said the company plans to launch many space telescopes and more spacecraft to begin the first for-profit mining of asteroids by 2045. Su added that NEO-01 will serve as a prototype (雏形)of future space mining robots, which can use rich mineral resources on asteroids to support the development of the space industry.
The Xinhua news agency reported that China was increasing efforts to land a spacecraft on a near-Earth asteroid to collect materials. China is also speeding up a plan to build a defense system against near-Earth asteroids. The country aims to follow Russia and the United States in becoming a major space power by 2030.
49．Which of the following can correctly describe NEO-01?
A．It weighs 60 kilograms.
B．It was created by Planetary Resources.

Passage 14
（2021·广东深圳市·高二期末） China’s Tianwen-1 spacecraft, in orbit around Mars’ has dropped its lander and rover (巡视器), named Zhurong after a Chinese god of fire, completing the most dangerous stage of its ten-month mission.
This is China’s first mission to Mars, and makes the country only the third nation to have landed a spacecraft there. It included an orbiter, a lander and a rover—making it the first to send all three elements to the planet.
“The mission is a big leap for China because they are doing in a single go what NASA took decades to do,” says Roberto Orosei, a planetary scientist at the Institute of Radio Astronomy of Bologna in Italy.
At a speed of 4.8 kilometers per second, the spacecraft departed Earth in July 2020 and arrived at Mars in February 2021, but the landing was the biggest test yet of China’s rising outer space exploration capabilities.
Landing on Mars is extremely difficult, because engineers back on Earth have no control over it in real time, and must leave pre-programmed instructions to carry on. Many missions have been lost, or have crashed on arrival.
Utopia Planitia, where Zhurong now sits, is a wide, flat area in a vast basin that formed when a smaller object crashed into Mars billions of years ago, “If the researchers are really fortunate, they might find some very ancient rocks, which could offer a window into our own planet’s history,” says Joseph Michalski, a planetary scientist at the University of Hong Kong, “Most of the similar evidence here on Earth has been destroyed by plate tectonics (板块运动).”
Zhurong will also be the first rover equipped with an instrument to measure the magnetic field (磁场) nearby. The instrument could provide insights into how Mars lost its strong magnetic field, an event that transformed the planet into a cold, dry place, uninviting to life.
A successful Mars landing could motivate more-advanced Chinese missions—including a sample-return one, which is planned to take place by 2030.
53．What makes Tianwen-1 mission unique?
A．Its multi-task in one try. B．Its long completion time.
C．The danger of the landing. D．The speed of its spacecraft.
54．Why is it so hard for the spacecraft to land on Mars?
A．The landing ground is not flat.
B．Instructions are too complicated.
C．It may crash into smaller objects.
D．Engineers have no live control over it.
55．What can researchers learn according to Joseph Michalski?
A．More of the Earth’s history.
B．The formation of vast basins.
C．The discovery of ancient rocks.
D．The destruction of evidence on Earth.
56．What’s the text mainly about?
A．Zhurong landed on Mars successfully.
B．Zhurong measured Mars’ magnetic field.
C．Tianwen-1 spacecraft orbited around Mars.
D．Tianwen-1 spacecraft returned to the Earth.

Passage 15
（2021·四川省仁寿第一中学校北校区高二月考） The lander carrying China’s first Mars rover successfully touched down on the red planet early Saturday morning Beijing Time May 15, 2021. It is the first time China has landed a probe on a planet other than Earth.
Tianwen-1, consisting of an orbiter, a lander and a rover, was launched from the Wenchang Spacecraft Launch Site on the coast of southern China’s island province of Hainan on July 23, 2020. This is the first step in China’s planetary exploration of the solar system, with the purpose of completing orbiting, landing and roving on the red planet in one mission.
The name Tianwen, meaning “questions to Heaven”, comes from a poem written by the ancient Chinese poet Qu Yuan (about 340-278 BC). China’s first Mars rover is named Zhurong after the god of fire in ancient Chinese mythology, which echoes with the Chinese name of the red planet: Huoxing (the planet of fire).
Tianwen-1 was launched via a Long March-5 rocket, China’s largest launch vehicle. Tianwen-1 has been traveling in space for nearly 10 months. It has carried out four orbital corrections and a deep-space maneuver. It had flown 475 million km and was 192 million km from Earth when it reached Mars orbit.
The craft’s plummet through the Martian atmosphere, lasting about nine minutes, was extremely complicated with no ground control, and had to be performed by the spacecraft autonomously.
“Such a challenging attempt is characterized by a succession of complex activities that must be conducted completely by the spacecraft within a very short period of time,” said Geng Yan, an official with the Lunar Exploration and Space Program Center of the CNSA．“What added to the difficulties was that we don’t know much about the Martian atmosphere, which brought a lot of uncertainties to the mission. Each step had only one chance, and the actions were closely linked. If there had been any flaw, the landing would have failed.”
57．What is the mission of Tianwen-1?
A．To record the wind speed on Mars. B．To accomplish three major tasks on Mars.
C．To search for aliens in the solar system. D．To explore the atmosphere of Mars.
58．What do the numbers in paragraph 4 mainly indicate?
A．The expense of traveling in space. B．The surroundings of the Mars orbit.
C．The huge task of Tianwen-1. D．The size of the Long March-5 rocket.
59．Why was it difficult for the spacecraft to plummet?
A．It had to complete the actions independently. B．It was too fast to be controlled.
C．It had traveled in space for a very long time. D．It carried too many supplies.
60．What can we know from Geng Yan’s words?
A．Landing on Mars is a very challenging move.
B．China’s attempt to explore Mars is successful.
C．People are enthusiastic about exploring the universe.
D．Tianwen-1 is essential to China’s space station program.

Passage 16
（2021·保定市第三中学高二期末） Jose Hernandez made his dream of becoming an astronaut a reality and he did so despite unbelievable difficulties.
“I was working in a field near Stockton, and I heard on my radio that Franklin Chang-Diaz had been selected for the Astronaut Corps,” said Jose, who was a senior in high school at the time. “I was already interested in science and engineering,” Jose remembered, “but that was the moment I said, ‘I want to fly in space.’”
As one of four children in a migrant (移民) farming family from Mexico, Jose — who didn’t learn English until he was 12 years old — spent much of his childhood traveling with his family from Mexico to southern California each March, then working northward to the Stockton area by November, picking strawberries and cucumbers at farms along the route. They would then return to Mexico for Christmas and start the cycle all over again in the spring. “Some kids might think it would be fun to travel like that,” Jose laughed, “but we had to work”.
After graduating from high school, Jose was admitted into the University of the Pacific. In 1987, he accepted a full-time job with Lawrence National Laboratory. In 2001, Jose joined the Johnson Space Center, where he came face-to-face with Franklin Chang-Diaz.
“We actually had common experiences — a similar upbringing, the same language issues. That built up my confidence. Any barriers that existed, he had already overcome them.” Jose smiled. “Now it’s my turn!”
“NASA rejected me not once, not twice, not three times but 11 times. It wasn’t until the 12th time that I got selected,” he said. Jose was selected as part of the 19th class of astronauts in 2004. He circled the globe 217 times but remains a down to Earth guy.
Jose Hernandez received the 2016 National Hispanic Hero Award and he continues his long history in the field of engineering and space.

Passage 17
（2021·河南开封市·高二期末） In the last century, a series of missions have been carried out to explore the moon—Earth’s only natural satellite. Among them, NASA’s Apollo 11 mission was groundbreaking as it succeeded in landing the first humans on the moon on July 20,1969.
Several decades later, NASA announced its Artemis program. Named after the Greek goddess of the moon and twin sister of Apollo, the Artemis program will send humans to the moon by the year 2024. And this time, the moon will welcome its first female astronaut.
Up until now, only 12 people, all male, have ever walked on the moon. “The last person walked on the Moon in 1972,” Bettina Inclan, NASA communications director said in a statement. “No woman has ever walked on the lunar surface.”
Women, of course, have been involved in space projects and made valuable contributions. In 1963, astronaut Valentina Tereshkova from the Soviet Union became the first woman to blast off into space. However, the progress toward women's access to space flight programs has been slow. Women have been held back by various requirements and security concerns. For example, astronauts had to be test pilots with a certain amount of experience. This was a problem as the field was dominated by males at the time. Indeed, the gender bias seemed to exist in the early space programs, The New York Times reported.
In 1962, NASA wrote to a little girl who wanted to be an astronaut. The letter said, “We have no present plans to employ women on spaceflights because of the degree of scientific and flight training, and the physical characteristics, which are required.”
Women have indeed made progress in this particular area, and arguably have advantages over their male colleagues. Women tend to be smaller, which means they use less oxygen and take up less space in small spacecrafts. Also, women usually have greater emotional awareness and communication skills that make them better-suited to long spaceflights.
Despite challenges, women have shown that they are more than capable of joining that elite group of men who have gone to the moon. And this will truly be a remarkable moment in history.
65．Which one is true about the Artemis program?
A．It is named after Apollo.
B．It will send 12 people to the moon by 2024.
C．It succeeded in landing the first humans on the moon.
D．It will send the first female astronaut to the moon.
66．The letter to a little girl is mentioned to show ________.
A．women's space flight programs are in progress.
B．women require more flight training on spaceflights.
C．the gender bias seemed to exist in the early space programs.
D．female astronauts have advantages over their male colleagues.
67．What’s the author’s attitude to sending female astronaut to the moon?
A．ambiguous. B．hopeful. C．indifferent. D．negative.
68．What’s the best title of the text?
A．Giant leap for women. B．NASA's Apollo 11 mission.
C．The first female astronaut to the moon. D．Who is more suitable for spaceflights—male or female?
Passage 18
（2021·长丰北城衡安学校） China has become the first country to successfully land a spacecraft on the far side of the moon. The Chang’e 4 probe has also made the first moon landing since1972. It has the task of exploring the side of the moon that never faces the Earth. The dark side of the moon is older and has a thicker surface than the visible side. It takes the moon as long to go around on its own axis as it does for one complete orbit around the Earth.
The Chinese probe landed in a huge crater 2,500 km in diameter and 13 km in depth. The crater is one of the oldest parts of the moon and our solar system.
Scientists hope to learn more about the geology of the far side of the moon. The craft has two cameras on board which will send images back to the Earth. It will also try to send signals to distant regions of space, something that cannot happen on Earth because of too much radio noise.
Chang’e 4 also has instruments on board to examine minerals as well as a container with seeds which will try to create a miniature biosphere.
Communication with the spacecraft is not easy. Images and other data must be transmitted to a separate satellite because no direct communication with the Earth is possible.
For China the Chang’e 4 mission is an important achievement, because the country has successfully done something no other nation on Earth has done. It wants to become a leading power in space exploration and has announced plans to send astronauts to the moon and set up its own space station.
69．Where did the Chang’e 4 probe land?
A．On the side of the moon facing the Earth. B．In a previous space station.
C．In a younger crater on the moon. D．On the invisible side of the moon.
70．What can we learn from the text?
A．The dark side of the moon is as cold as the other side.
B．The bright side is younger and thinner than the other side.
C．Other places in space may hardly receive signals from the craft.
D．The two cameras on the craft can send pictures to the Earth easily.
71．Why is the craft equipped with a container?
A．To see what seeds can come out on the moon.
B．To collect some important matter on the moon.
C．To find whether the seeds can grow on the moon.
D．To check whether some minerals exist on the moon.
72．According to the text, what will China do in the future?
A．Land manned spacecraft on the moon. B．Build another space station on the moon.
C．Launch more space probes to the moon. D．Become the first country in exploring space.

Passage 19
（2021·山东泰安市·高二月考） Scientists found the moon may hold water in more places and in larger amounts than they have suggested in the past. The finding is based on studies that examined the new data from the U.S. space agency NASA．The discovery could be important for planned, long-term human bases on the moon. It could mean that enough resources exist on the moon itself to provide drinking water and possibly help produce rocket fuel.
Until about ten years ago, scientists believed the moon was mostly desiccated. But a series of findings provided evidence that water ice was widespread in small amounts on parts of the moon. The ice was thought to be in areas permanently blocked from sunlight.
But in the new studies, NASA said it was able to confirm the presence of water molecules (分子) on sunlit parts of the lunar surface. The research was led by Casey Honniball of NASA's Goddard Space Flight Center in Maryland.
Scientists have suggested the source of the water may come from comets (彗星), solar wind or interplanetary (星际的) dust. The new research provides evidence the water may be surviving on sunlit lunar surfaces because it is attached to minerals.
“A lot of people think that the discovery I have made is water ice, which is not true,” Honniball said. “It's just the water molecules-because they are so spread out that they don't interact with each other to form water ice or even liquid water.”
“Water is extremely important for deep space exploration. It's a resource of direct value for our astronauts,” Bleacher said. He noted that water is heavy and costly to transport from Earth. He told reporters the agency believes it is very important to find out more about where the water comes from and how accessible it is.
“Anytime we don't need to pack water for our trip, we have an opportunity to take other useful items with us,” he said. That may include materials that could be used to carry out bigger scientific experiments on the moon.
73．How do scientists feel about the discovery?
A．Excited. B．Unconcerned. C．Calm. D．Doubtful.
74．What may the future research focus on?
A．How the water survives on sunlit lunar surfaces.
B．How to make use of the water on the moon.
C．How the water is attached to minerals.
D．How much water is on the Lunar surface.
75．What is the special part of the water on the moon?
A．It comes from other planets.
B．It is safe to drink.
C．It can't be used directly.
D．It can't be found in the dark areas.
76．Which can be a suitable title for the text?
A．Moon Space Bases will be Built
B．More Water May Exist on the Moon
C．Space Exploration Gets into New Age
D．Liquid Water is Discovered on the Moon

Passage 20
（2021·贵州贵阳市·高二期末） China’s Chang’e 5 space craft, tasked with bringing lunar(月球的) rock samples to Earth, successfully landed on the Moon on December 1st, 2020. The 8,200kg spacecraft, set off from China’s Wenchang Spacecraft Launch Site on November 23,2020, entered the satellite’s orbit(轨道) on November 28th, 2020.
With 19 hours of landing, the probe(探测器) gathered about 2 kg of rocks and soil by digging almost 2 meters deep into the lunar surface using its robotic arm. The sample-filled jar was placed in the ascender vehicle (上升器), which left the Moon’s surface and entered the lunar orbit on December 3rd, 2020. Then, in a historic first, the ascender and Chang’s 5 orbiter(轨道器) spacecraft successfully came together on December 6, 2020 to complete the first-ever robotic rendezvous and docking(对接) in lunar orbit.
“In terms of the space tasks that humans have performed so far, only the Apollo program missions have complete the rendezvous and docking in lunar orbit. However, unscrewed rendezvous and cocking have never been done before,” Peng Jing, deputy chief designer of the Chang’e 5 probe from the China Academy of Space Technology (CAST), told Chinese media ahead of the attempt.

Passage 21
（2021·四川眉山市·高二期末） In the distant past, our ancestors relied on stars to guide them on a clear night. Today, we have navigational(导航的)systems to help us find our way, the latest of which is the Beidou Navigation Satellite System (BDS).
The BDS is entirely built by Chinese engineers. With the launch of the last satellite from the Xichang Satellite Launch Center on June 23, the global network of 59 satellites has been completed. On July 31, Beidou started providing services covering our whole planet.
It’s difficult to imagine the great influence those satellites have on our daily lives. When you unlock one of Hellobike’s bicycles, you are using the BDS. “The intelligent lock on each bike receives Beidou satellite signals and sends positioning information to the data center which will help collect big data on the bikes and predict users’ riding needs in advance according to the data,” Chu Yiqun, a manager of Hellobike mentioned. Users can also find shared bikes more accurately(精确地) thanks to Beidou’s global positioning accuracy of 2.34 meters.
Beidou adopts a unique two-way communication system, including its ability to receive messages sent by people from areas with poor communication signals. Obviously this function isn’t designed for users to chat online. Instead, it plays a role when disasters occur and communications are blocked.
After the Wenchuan Earthquake in 2008, all ground-based communication facilities were interrupted. Though the first generation of Beidou could only send 120 characters in a single message at that time, communication between affected areas and rescue(救援) centers was successful. Now, Beidou’s messaging ability has been increased to 1, 200 Chinese characters in a single message. It is widely used in disaster alarms, automatic identification and information release.
As Sun Jiadong, former chief designer of the BDS said: “The application(应用) of Beidou is only limited by imagination.”
81．What can we learn about the BDS from the passage?
A．It was developed by Chinese and American engineers.
B．It works better on clear nights.
C．Its last satellite was launched on July 31.
D．It’s able to provide global coverage for navigation.
82．Why does the author mention Hellobike in Paragraph 3?
A．To stress the excellent positioning ability of the BDS.
B．To show how the BDS makes people’s daily lives easier.
C．To present the advantages and disadvantages of the BDS.
D．To explain how the BDS works.
83．What is Beidou’s two-way communication system designed for?
A．To help people when communication signals are poor.
B．To make users’ daily communication more fun.
C．To allow users to chat online more freely.
D．To collect data from users for the data center.
84．What does the underlined sentence in the last paragraph mean?
A．Beidou may be more helpful than we know.
B．Beidou inspires users’ imagination.
C．Beidou needs to be further improved.
D．Beidou is limited in application.

Passage 22
（2021·江苏无锡市·高二期末） The moon hasn’t had an easy time over the years. Since the beginning of the solar system 4.5 billion years ago, its gray and lifeless surface has been repeatedly hit by space rocks, leaving behind a landscape full of broken stones. Beneath this surface, however, hide the moon’s most attracting secrets for human explorers, from a large amount of ice for producing drinking water to rocket fuel. More importantly, mapping the moon’s subsurface can show some hidden periods of solar system history. This is confirmed by fresh results from a Chinese rover (月球车).
The latest results come from the Chang’e-4 mission, run by the China National Space Administration. Launched in December 2018 and reaching the moon in early January 2019, the mission became the first to land on the far side of the natural satellite, targeting a region near the lunar south pole called the South Pole-Aitken Basin. The Chang’e-4 rover is still operational today and has been slowly moving across this region, traveling a few hundred meters since it landed.
Using a radar instrument on Chang’e-4, researchers have found that the rover is likely sitting on different layers of ejecta ( 喷 出 物 ) and a very clear order of layers can be seen. The rover’s radar instrument was able to enter up to 40 meters below the surface of the moon, more than twice the distance achieved by the former, the Chang’e-3 mission, which landed on the moon near side in December 2013. Data from the latest mission show three different layers beneath the rover. It is not currently possible to date the layers under Chang’e-4. But they do provide some information about lunar history dating back about four billion years.
The rover is continuing to move across the surface, making regular stops to take measurements and use its instruments.
85．What is the most important purpose of human’s exploration of the moon?
A．To seek fresh drinking water.
B．To find hidden rocket fuel.
C．To study different layers of ejecta.
D．To uncover the hidden history of solar system.
86．What do we know about the the Chang’e-4 mission?
A．It landed on the moon about five years later than Chang’e-3.
B．It is the first to travel around the moon during the exploration.
C．It took over a year from launch to land the far side of the moon.
D．A radar instrument helped it to enter 40 meters below the surface of the moon.
87．In which part of a magazine can this passage be read?
A．Historical Story. B．Science Fiction.
C．Scientific Front. D．Chinese Economy.
88．Which of the following can be the best title for the article?
A．China’s Moon Rover — a Deeper Look At the Far Side
