They are 2 places with very cold temperatures and few people live there. 3 , the north is not so similar to the South Pole as people may imagine.The north Pole has no land, only thick ice. Temperatures 4 go above 32 ºF, at which water turns into ice. Most of the time, it stays below zero. In winter temperatures are usually as low as 30°F. Although conditions were very poor, people tried for many centuries to 5 the North Pole. About 100 years ago, two men, Robert Peary and Mathew Henson, were able to get to this environment 6 of troubles and difficulties. They reach the North Pole on March 8th, 1909. It was really a 7 trip for them.There are few things more dangerous than crossing the Arctic (北极圈) on foot. People who stayed there may face many problems: very cold temperatures, sudden storms, even hunger. Most of the area is uninhabited(无人居住的). 8 people can live in such a difficult place.People might think that with such low temperatures for most of the year, the ice would be 9 and hard. However, this is not true in the arctic. The movement of the ocean water under the ice may often cause many different changes on the surface. Sometimes the ice 10 into two opening lanes of water called “leads”. Anyone who falls into a lead can be frozen to death in a few minutes.1．A．differentB．similarC．sameD．hard2．A．bothB．neitherC．allD．some3．A．ButB．ThoughC．ThereforeD．However4．A．alwaysB．neverC．seldomD．often5．A．getB．reachC．arriveD．go6．A．filledB．packedC．kindD．full7．A．hardB．happyC．easyD．relaxing8．A．ManyB．LittleC．FewD．Much9．A．thinB．thickC．softD．slim10．A．cutsB．breaksC．fallsD．turns四、补全对话。(本大题共5小题，每小题1分，共5分)阅读下面对话，从7个选项中选择5个恰当的句子完成此对话。A: Hi, Sarah.

D．Engineers.BRainforests (热带雨林) are some of the most amazing places on Earth. They cover only about 6% of the world’s land, but are home to more than half of all living things. These dense forests are full of life, from tiny insects to large animals, and from small plants to tall trees.The rainforest has different layers. The top layer is called the emergent layer, where the tallest trees reach up to 70 meters. Below that is the canopy, a thick layer of leaves and branches that stops most sunlight from reaching the layers below. Next is the understory, with smaller trees and bushes. The bottom layer is the forest floor, where only a little sunlight gets through.Many rainforest animals have special skills to live in their layers. For example, sloths hang from the canopy branches. Their long claws help them stay there, and their slow movement helps them save energy. Toucans have big beaks to reach fruit on thin branches that can’t hold their weight. On the forest floor, jaguars use their spots to hide in the shadows while hunting.Rainforests are important for the whole world. They take in carbon dioxide (二氧化碳) and give out oxygen (氧气), which helps keep the air clean. They also help control the world’s weather. But rainforests are in danger. Every year, large areas are cut down for wood or to make space for farms. This destroys the homes of many animals and plants, and may even change the world’s climate.5．What does the word “dense” mean in the first paragraph?A．Dry.B．Thick with plants.C．Cold.D．Easy to walk through.6．Why do toucans have big beaks?A．To hang from branches.B．To hide from predators.C．To reach fruit on thin branches.D．To run fast on the forest floor.7．Put the layers of the rainforest from top to bottom.①understory ②emergent layer ③forest floor ④canopyA．②→④→①→③B．④→②→①→③C．②→①→④→③D．④→①→②→③CHow do you feel about nature? After spending hours indoors, do you feel better when you visit your local park? I believe the answer must be “YES”. We should walk into nature so that we can enjoy the natural beauties around.Most people think that nature is good for our bodies and brains. However, humans are spending more time inside and less time outside. For example, the number of visitors to Canada’s national parks is getting lower every year. And in countries such as the USA, only 10% of teenagers spend time outside every day. Many doctors feel that this is a problem in the twenty-first century.As a result, some doctors are studying the connection between nature and health: one example of this is the work of Dr. Matilda in Sweden. The doctor gave people a math test. During the test, their heart rates (心率) were fast. After the test, one group of people sat in a 3D-virtual-reality (虚拟现实) room for fifteen minutes with pictures and sounds of nature. Their heart rates were slower than people’s in the other group.The virtual touch with nature helped them feel more relaxed. The natural world allows our brains to rest and slow down, and can trigger (触发) positive feelings and a sense of peace. Being in nature can leave us feeling happier and less stressed. Another good example of how nature is good for health comes from Canada. In Toronto, researchers studied 31,000 people living in the city. In general, they found that healthier people lived near parks.Because of studies like these, some countries and cities want nature to be part of people’s everyday life. In Dubai, for example, there are plans for a new shopping mall with a large garden so shoppers can relax outside with trees, plants and water. And South Korea is another good example: it has new forests near its cities and around 13 million people visit these forests every year. Being close to nature has been thought to be necessary for brain development in children. In Switzerland, “forest schools” are popular. Schoolchildren study their subjects in the forests and do lots of exercise outside. So after building cities for so long, perhaps it’s now time to start rebuilding nature.Nature holds a special kind of energy; it is pure and wild and spirit-renewing. In a word, the human being cannot live without nature, and Mother Nature makes us grow stronger.8．What does Paragraph 2 mainly talk about?A．A problem in the 21st century.B．How much time we spend outdoors.C．Visiting your local parks.D．Feeling about nature.9．What do the results of the studies chow?A．More and more Canadians will live near parks.B．The math test is difficult and makes people nervous.C．Nature can help people feel more relaxed and be healthier.D．People’s heart rates get slower in a 3D virtual reality room.10．What can we learn from the last sentence of the passage?A．Nature is more important than cities.B．Country life is healthier than city life.C．People have lived in the cities for so longD．Nature should be part of people’s daily life.D阅读下面短文，完成短文后的问题。In 1640, a man was seriously ill. He had to end the last trip of his life. Back home, people asked him, “You spent your whole life on the road. Do you regret (遗憾) it?”“I walked through many fantastic places in China,” he replied. “People say I’m as great as Zhang Qian and Xuanzang. So I have no regrets at all.” This man was Xu Xiake. He was the greatest traveller (旅行家) in Chinese history.From an early age, Xu dreamed of visiting China’s seas and mountains. But at the time, it was very difficult to travel far. However, this didn’t stop him. At 22, he set out on his life’s journey. He travelled for about 30 years, and achieved his dream.Xu made many geographical discoveries during his journey. Once, he visited Mount Huangshan. People then thought Tiandu Peak was higher than Lianhua Peak. To find out the truth, Xu climbed both peaks. He discovered that Lianhua Peak gave a wider view, so it must be higher. He was right!Xu recorded his travel experiences in his diary. This later became Xu Xiake’s Travel Notes. Thanks to this book, we can learn about China almost 400 years ago. “Exploring the unexplored” is the best description of Xu’s life.11．What was Xu Xiake’s dream?

They span across eight US states and two Canadian provinces.Part 2: Comparison· Lake OntarioThis lake has the smallest surface area at 7,340 square miles. Three dams (大坝) control the flow of water downstream and include locks so boats can enter from the Atlantic.· Lake HuronThis is the second largest lake by surface area in the system and home to Manitoulin Island, the world’s largest freshwater island.· Lake MichiganIt is joined to Lake Huron by the five-mile-wide Straits (海峡) of Mackinac, though they are still classed as two separate bodies.· Lake ErieWith a maximum depth of 64 metres, this is the shallowest of the Great Lakes. It is generally the warmest, but also gets frozen more quickly than the others.· Lake SuperiorAt 406 metres deep, the distance from the lake’s surface to its deepest point is about the same as the length of four football pitches.Part 3: Covering an area of 94,250 square miles, these huge bodies of water take up more than one-fifth of the world’s total freshwater. The Great Lakes provide drinking water for more than 40 million people, important shipping routes for more than 800 ocean ships, and keep a rich ecosystem for fishing and agriculture. They also support wildlife, the national economy and the environment.
