第一节 阅读下列短文, 从每题所给的 A、B、C 和 D 四个选项中, 选出最佳选项。

A

Nature has inspired many of the most fascinating designs around us, including those in architecture. Today, architects continue to explore ways to capture the beauty of natural forms, to mimic the way nature works or even to make natural organisms part of a building.

Art Science Museum, Singapore

People whose interest is exploring the relationship between art and science will enjoy Singapore’s Art Science Museum. The building was designed to show the connection between nature and the modern city environment in which it sits. Shaped to resemble a lotus flower, it appears to float above the waterfront promenade(滨海步道)and the water that surrounds it. Its roof collects rainwater and channels it 35 meters down to a waterfall in the centre of the space. The water is then recycled through the building’s plumbing system. The building so truly captures the beauty of natural forms.

The Algae House, Hamburg

The world’s first algae-powered building is in Hamburg, Germany. The surface of the apartment building is covered in panels that contain algae（水藻）. In bright sunshine, they grow faster and provide shade. The panels also capture heat from the sun and convert it into energy that powers the building. And that’s not all — the algae inside the panels can be harvested and used to produce fuel. The building therefore not only responds to its environment and uses less energy, but also reduces damage to the environment by generating its own renewable energy.

Creating building such as these enables us to live in closer harmony with our environment. To meet the needs of today while protecting the world of tomorrow may be a challenge, but even the simplest organisms can help teach us how to achieve this.

21．Which of the following is NOT the reason why architects continue to explore nature?

A．To imitate the way nature works. B．To make nature part of architecture.

C．To capture the beauty of nature. D．To make natural organisms alive.

22．How can the Algae House reduce damage to the environment?

A．By using less energy. B．By providing shade for people

C．By capturing heat from the sun. D．By producing its own renewable energy.

23．In which magazine would you most likely find the passage?

A．Architecture Frontier. B．Extraordinary Architects.

C．Natural World. D．Living on Earth.

B

First, all participants found it quite easy to link colors and emotions. This was particularly true for colors like red, black, or yellow. Other colors, like brown and purple, received fewer associations. We found that colour-emotion associations were not one-to-one, but many-to-many.

Participants did not select one emotion for a colour, but often chose several emotions. In turn, different colors were linked to the same emotion, like pleasure, which was associated with red but also yellow, orange, pink and purple.

What you can also see is that most colors were associated with positive emotions. Only brown, grey and black—that is, darker colors—were associated with negative emotions. Red was the most controversial colour. For some, it was a very positive colour—the colour of passion, love and desire. For others, it was a negative colour—the colour of danger, anger and hate. For even others, it was both positive and negative. What connects all these emotions and ideas is the fact that red is activating and strong.

Second, we found few cultural differences. In other words, many colour-emotion associations seemed universal. Most participants agreed that pink was associated with love and pleasure, yellow with joy and amusement, or that black was the saddest colour.

Third, if you are interested in cultural differences, we found some specificity too. For example, in addition to the universal associations of love and anger with red, Chinese participants also associated joy and amusement, while Nigerian participants additionally associated fear with red. Another example is the association between purple and sadness that only Greek participants chose. For others, purple was generally a positive colour with very little agreement on the exact emotions associated with purple.

Fourth, participants whose languages were more similar to each other also had more similar associations. To arrive at this finding, we estimated the degree of linguistic (语言的) similarity between two languages, which shows how related or unrelated they are. And then, languages from different language families, like English and Chinese, would have the lowest similarity scores.

24．Which colour is most likely to cause controversy?

A．Black.  B．Yellow. C．Red  D．Brown.

25．What is pink associated with according to most participants?

A．Joy and amusement.       B．Love and pleasure.

C．Anger and sadness.          D．Fear and disappointment.

26．Which group of people associate purple with sadness?

A．Greek participants.          B．Nigerian participants.

C．Chinese participants.         D．English participants.

27．What’s the best title of the text?

A．The Deep Meaning of Colours

B．Linguistic Similarity Between Two Languages

C．Cultural Differences in Different Countries

D．The Link Between Colours and Emotions

C

Zheng Qinwen announced herself as a major new force in women’s tennis with an important French Open debut(首秀) last month. Now the Chinese teenager hopes the fighting spirit she showed at the Grand Slam (大满贯) tournament can encourage kids starting out in the sport to chase their dreams on the court with the same determination.

“If tennis is your dream, I think you always have to fight for your dream. Because we only have one life, you shouldn’t have any regrets,” Zheng said last week in an interview.

The 19-year-old showed she possesses the talent to be a contender at the very top level of tennis with a breakout campaign at French Open.

Accounting for two-time Grand Slam winner Simona Halep along the way, Zheng’s journey was ended in the fourth round by a three-set defeat to eventual champion Iga Swiatek. Zheng, though, gave the Polish world No. 1 a big scare, battling back from 3-0 down in the first set to force and win a tiebreak(平分决胜局).

“That was the first time I had played against the world No.1, so I really wanted to grab this chance so I could judge her level and test myself,” said Zheng. “I didn’t want to give her the match so easy like that. It was pretty difficult for me to hold on in that match because of what my body was going through, but I wanted to show her I’m not easily beaten.”

Looking back at Zheng Qinwen’s performances in this year’s French Open, there’s no doubt that she’s a true fighter. Zheng says she avoids being discouraged by higher-ranked opponents by simply focusing on the next point, one shot at a time. Supported by her team, she hopes she can one day win a Grand Slam title.

Zheng’s impressive French Open run has inevitably(不可避免地) led to comparisons with China’s solitary Grand Slam singles champion Li Na, who won the 2011 French Open and 2014 Australian Open titles.

“When I was a kid, Li Na showed that Asian people also can do something really good in tennis. She was the first one. I will just focus on my own game and then let’s see if I can really compete at the highest level,” said Zheng.

28. What does the underlined word “contender” in paragraph 3 mean?

A. announcer B. campaigner.           C. competitor D. designer.

29. What is the result of the match between Zheng and Iga Swiatek?

A. Iga Swiatek beat Zheng easily.

B. Zheng won the match despite her pain.

C. Zheng lost to Iga Swiatek at last.

D. Iga Swiatek lost because of her mistakes.

30. Why is Li Na mentioned in paragraph 7?

A. To prove failure is the mother of success.

B. To show how excellent Zheng Qinwen is.

C. To explain why Li Na has achieved a lot.

D. To compare the difference between Zheng Qinwen and Li Na.

31. Which of the following can best describe Zheng Qinwen?

A. Hardworking and determined.              B. Optimistic and generous 

C. Adventurous and realistic.                  D. Independent and helpful 

D

On September 26, 2022, NASA successfully completed its Double Asteroid Redirection Test (DART) mission by intentionally crashing an unmanned spacecraft into the asteroid（小行星）Dimorphos. The goal was not to destroy the asteroid but to change its orbit. With the successful mission, NASA proved the concept that this technique could keep a potentially dangerous asteroid from crashing into Earth in the future.

Dimorphos is a small asteroid orbiting the larger asteroid Didymos. NASA noted that Dimorphos is not a threat to Earth, but because it passes relatively close to Earth, it was chosen as the target for the test mission.  

Although the intended crash should change the asteroid’s position slightly, it will add to a major shift over time. “If you were going to do this for planetary defense, you would do it 5, 10, 15, or 20 years in advance for this technique to work,” said NASA program executive Andrea Riley. “This is why we test. We want to do it now rather than when there’s an actual need.”

Asteroids can pose a significant threat to planet Earth. For example, around 66 million years ago, an asteroid around 6 to 9 miles across struck the Earth in what is now the Yucatan Peninsula. The resulting impact was so catastrophic（灾难性的）that it caused one of the largest extinction events in Earth’s history. Therefore, DART’s success is an important step forward in protecting the planet from potential damage from an asteroid. This shows humans are no longer powerless to prevent this type of natural disaster.

The DART spacecraft was launched by NASA on November 24, 2021. It was accompanied by another craft called LICIACube, supplied by the Italian Space Agency, and separated from DART just 15 days before the crash. LICIACube remained in orbit around the asteroid and took photographs of the crash and material ejected（弹出）from the asteroid’s surface.

32.What is the purpose of the DART mission? 

A. To destroy Dimorphos completely.

B. To change the orbit of Dimorphos.

C. To track potentially dangerous asteroids.

D. To prevent Dimorphos from hitting the Earth.

33. How can we describe the test according to Andrea Riley? 

A. Better late than never.

B. Rob Peter to pay Paul.

C. Prepare for a rainy day.

D. Bark up the wrong tree.

34. Why does the author mention the example in paragraph 4? 

A. To prove the significance of DART’s success.

B. To present the effect of the largest extinction events on humans.

C. To explain the difficulty of protecting the Earth from asteroid strikes.  

D. To show the necessity of conducting research on natural disasters.

35. What is LICIACube intended for? 

A. Recording the crash test with photos.

B. Collecting rock samples from Dimorphos’s surface.

C. Providing additional energy for the DART spacecraft.

D. Increasing the force of crashing the DART spacecraft into Dimorphos.

The last race of the day was over. My breathing gradually stilled along with the ripples（波纹）in the pool, but I stayed in the water, watching sadly as the winners gathered for the medals ceremony.

"Don't look so sad,"I heard a voice say behind me. I turned around to see a tall, blond, blue-eyed man standing on the edge of the pool. "You came in fourth, but you are the best in your country."he said smiling,"I'm Ken Schafer, and you?"

"Rima Datta."

"And how old are you, Rima?"

"Fourteen, Sir."I replied lifting myself out of the water. Ken was a swimming coach from California and asked me about my life as a swimmer until then.

My eldest brother, Anil, had taught me how to swim, but I had no real training until I was nine when a coach from the National Institute of Sports came for just three months a year to train the boys at Mayo College, where our father taught. She set aside a couple of hours a week for the daughters of the staff. It was she who had corrected my mistakes and encouraged me to take part in competitions.

Surprised to hear how little steady training I had had, Ken introduced me to the National Institute of Sports in Patiala to be trained in this summer. The train was hard, and I felt quite lonely away from my parents and all that was familiar. But it was Ken,with his tireless enthusiasm, his passion for swimming, and his faith in me that kept me focused.

I won my first gold medal at the national championship that year, a fact that filled me with immense joy and Ken with a sense of satisfaction that his work with me was paying off. Yet he realized that what I really needed was a team to train with and steady coaching year-round.

Then he persuaded my parents to allow me to go to California and train there for a year. He even helped find out a host family for me.

Failure is the most common thing in our daily life. We can encounter a number of difficulties  and failures everywhere. Therefore, how to face failure is of vital importance.

Undoubtedly, no one likes failure. It makes us feel down and even brings terrible       consequences，some of which we can’t bear. However, it is advisable for us to know that we can    have a better understanding of our shortcomings. When it comes to how to face failure, my         suggestions are as follows. Firstly, I will reflect on myself and try to find out the main reason.   Meanwhile, I will also share my sorrow with my teachers and friends who will give me more     reasonable and practical advice to overcome failure. More importantly, home is the best harbor.      Therefore, turn to your parents for help, if necessary.

All in all, don’t be afraid to face failure, which will be the foundation of success.

读后续写

Alone on the long flight to Los Angeles, I was filled with doubts, as I had never lived with a strange family. How would I manage to live with people I had never met before? What if I didn't get along well with the host family?Would I fit in? From the first moment at the airport where they had come to pick me up, I knew things would be all right. “Hi, I’m Henry. Nice to see you,Rima.” A boy with a bright smile said. “Nice to see you, too,” I said in a low voice. Then homestay father introduced family members to me and added, “Take it easy, Boy. You’ll feel at home here. And we’ll have steaks tonight! Hope you’ll enjoy it!” He patted my shoulder and then put my suitcase in the trunk of his car. I knew I could not find a kinder, more generous family than theirs.

10. Do you know how to get inexpensive airline and train tickets? On a recent flight, Laura was chatting happily with me in the seat until the conversation turned to fares. I bought my ticket 3 weeks in advance and paid $148. Laura paid the full fare of $480. She decided that next time she would find out how to travel for less. Here are some useful ways to travel for less. Cheap airline tickets. To fly for less money, you can buy non-refundable plane tickets 2 or 3 months before your trip. The cheapest way to fly is as a guide. In return for the service in a travel agency, you get a plane ticket that costs as little as one quarter of the regular fare or even less if the agency needs someone at the last minute. Recently, a guide flew a round trip from New York to Hong Kong for $100; a regular ticket costs around $1,800. Train passes. If you are going to do a lot of travelling by train, a train pass will save your money. Train passes can be especially useful in India, which has the world’s largest rail system, in Japan, where trains are fast and convenient, and in Europe, where trains go to over 30,000 cities. The Rail Europe Group even offers senior passes for those of 60 years of age and over, youth passes for those under 26 years of age, and provides a great bargain.
