According to a study in Nature Climate (气候) Change, the number of most polar bears will 1 rapidly (快速地) by 2080. There are two reasons. One is that the sea ice is melting (融化). Polar bears catch seals (海豹) to eat on the ice. 2 ice, they have to stay on land. But there is no 3 food on land to support so many polar bears. The animals could die from hunger. The other reason is that mother bears may not be fat enough to 4 milk for their babies, so some bears could stop having babies. Polar bears are 5 land animals that eat meat on the planet. They help control other kinds of animals. Losing them would break the balance of their living place. The Arctic is the 6 to about 25,000 polar bears. Arctic sea ice usually melts in spring and summer, then grows in winter. But now, the 7 is taking longer to grow back. Scientists say the Arctic is warming twice as fast as the rest of the planet. The study also shows 8 it is possible to slow Arctic melting. Greenhouse gases (温室气体) could lead to climate change. In order to avoid creating greenhouse gases, the world should try to stop burning coal and riding in cars. Saving the bears is 9 us. Holland, one of the writers of the study, says, “I believe there is hope, but humans need to act 10 to make that hope come true.” Let’s take action to protect our earth and save polar bears. 1．A．develop B．fall C．rise D．improve 2．A．Through B．Across C．Without D．Except 3．A．enough B．good C．sweet D．delicious 4．A．protect B．progress C．prepare D．produce(生产) 5．A．the largest B．the loveliest C．the simplest D．the luckiest 6．A．room B．family C．house D．home 7．A．sea B．ice C．plant D．animal 8．A．if B．when C．that D．whether 9．A．up to B．hard on C．good with D．thankful to 10．A．widely B．clearly C．quickly D．quietly 二、阅读理解 A Cheetahs (猎豹) and other wild cats (大型猫科动物) are in danger of dying out because they have few places to live and people hunt (猎杀) them. Can we help these wild cats in danger? Wildlife scientists hope so. They are trying to protect the wild cats by letting people know about their situation and thinking out some ways to keep them safe. Cheetahs are the world’s fastest land animals. Most cheetahs live in Africa. In the past 100 years, the number of cheetahs living in the wild has changed from 100 000 to fewer than 12 000. Good news for cheetahs at the Saint Louis Zoo! Three baby cheetahs that were born in November are growing up at the Saint Louis Zoo in Missouri. “The babies do well,” the zoo’s worker, Steve, said. “They are very active and playing with each other or with their mom.” By raising baby cheetahs, the zoo is working to save cheetahs from dying out. The zoo is also helping protect cheetahs in the wild. “We want children to know that cheetahs are in danger,” said Steve. “It is important to protect their living places.” 11．Why are cheetahs and other wild cats in danger of dying out? A．Because they have few places to live and people hunt them. B．Because they are easy to be ill. C．Because they have nothing to eat. D．Because people send them into the zoo. 12．Which of the following is TRUE about cheetahs? A．Most cheetahs live in Africa. B．They are the world’s fastest animals. C．They are in danger because of the weather. D．There are about 100 000 of them in the wild now. 13．What does the underlined word “They” here refer to? A．The workers. B．The scientists. C．Mom cheetahs. D．Baby cheetahs. 14．How does the Saint Louis Zoo in Missouri help cheetahs? A．By raising baby cheetahs. B．By making laws to keep them safe. C．By sending baby cheetahs into the wild. D．By building more and more houses for them. 15．What is the writer’s purpose? A．To tell us the number of cheetahs. B．To tell us about a zoo with cheetahs. C．To tell us the situation about cheetahs. D．To encourage us to do something for the zoo. B Whales are beautiful and interesting animals on the earth. Are they fish? In fact, they aren’t fish. 16 It’s amazing to think how big whales are. 17 They are more than 30 meters long and weigh about 80 tons each. They are heavier than 24 elephants. A new baby whale weighs as much as a big elephant. The blue whale also has the largest heart in the world. 18 Whales feed on sea life. Some whales eat seals and fish. Some eat plants. Some whales have teeth, while others don’t. 19 So they often jump out of water. Beaches are not safe places for whales. They need to stay in the sea. For whales, the mistake of landing on beaches is dangerous. 20 Some people may catch whales for meat, fat and oil. Whale parts are sold to makes things like candles and soap. A．So they can’t swim. B．It can be as heavy as 80kg. C．Whales must come to the top of the sea to breathe. D．Blue whales are the largest animals on the earth. E．They may lose their lives. F．But their homes are in the sea. 三、任务型阅读 阅读下面材料并按要求完成1至5小题。 The giant panda is one of the most popular animals in the world. A giant panda can grow up to 1.5 meters long and weigh up to 160 kg. People think the giant panda is very lovely. So it is not surprising that the World Wide Fund for Nature chose the giant panda as its symbol. The WWF tells people about animals that are in danger and raises money to save them. The giant panda only lives in the wild in China. In the early 1980s, there were only 1,000 left in the wild. The main reason why pandas are endangered is that the area where panda can live has become smaller. The WWF works to help giant pandas in the wild in many ways. One of the ways is to increase the size of panda reserves (自然保护区). Some reserves need to be joined together by planting bamboo between them to make “corridors”(走廊). These are paths that lead from one reserve to another. No one may harm the pandas in these areas. The corridors let pandas move from one habitat (栖息地) to another to look for food. ①People are working very hard to make sure the giant panda does not die out. 阅读以上材料，完成以下任务。 任务一：回答问题。 21．How long and heavy can a giant panda grow to be? 22．Why are the giant pandas endangered? 任务二：列举一个世界自然基金会帮助野生大熊猫的方法。(英文列举) 23．                                 任务三：根据短文内容，补全句子。 24．The corridors let pandas move from one habitat to another to .        任务四：翻译句子。 25．将文中①处画线句子翻译成汉语。 四、短文填空 阅读下面短文，在空白处填入一个适当的单词或括号内单词的正确形式。 The panda is one of the best-known animals in the world. However, they are now 26 danger. There are about 1,000 pandas living in nature reserves today. Zoos and research centers look after about 160 pandas. Scientists are studying how they live. When we got to the Chengdu Research Base at 8:00 a.m. yesterday, the panda keepers 27 (prepare) milk for the baby pandas’ breakfast. In fact, many people love these black and white animals. Pandas 28 (become)so popular so far. They are now a symbol of China. Pandas mainly live on bamboo, and adult pandas spend more than 12 hours a day 29 (eat) about 10 kilos of bamboo. Many years ago, there were a lot 30 (much) bamboo forests and pandas in China, 31 then humans started to cut down these forests. Pandas couldn’t find enough to eat and they didn’t have many 32 (baby), and baby pandas often died. The situation is becoming very serious now. Our government is working hard 33 (save) pandas. There are more than 30 nature reserves to protect them. 34 education program in Chengdu also teaches children about pandas and other endangered wild animals. Scientists are doing research.

According to a study in Nature Climate (气候) Change, the number of most polar bears will 1 rapidly (快速地) by 2080. There are two reasons. One is that the sea ice is melting (融化). Polar bears catch seals (海豹) to eat on the ice. 2 ice, they have to stay on land. But there is no 3 food on land to support so many polar bears. The animals could die from hunger. The other reason is that mother bears may not be fat enough to 4 milk for their babies, so some bears could stop having babies. Polar bears are 5 land animals that eat meat on the planet. They help control other kinds of animals. Losing them would break the balance of their living place. The Arctic is the 6 to about 25,000 polar bears. Arctic sea ice usually melts in spring and summer, then grows in winter. But now, the 7 is taking longer to grow back. Scientists say the Arctic is warming twice as fast as the rest of the planet. The study also shows 8 it is possible to slow Arctic melting. Greenhouse gases (温室气体) could lead to climate change. In order to avoid creating greenhouse gases, the world should try to stop burning coal and riding in cars. Saving the bears is 9 us.

Can we help these wild cats in danger? Wildlife scientists hope so. They are trying to protect the wild cats by letting people know about their situation and thinking out some ways to keep them safe. Cheetahs are the world’s fastest land animals. Most cheetahs live in Africa. In the past 100 years, the number of cheetahs living in the wild has changed from 100 000 to fewer than 12 000. Good news for cheetahs at the Saint Louis Zoo! Three baby cheetahs that were born in November are growing up at the Saint Louis Zoo in Missouri. “The babies do well,” the zoo’s worker, Steve, said. “They are very active and playing with each other or with their mom.” By raising baby cheetahs, the zoo is working to save cheetahs from dying out. The zoo is also helping protect cheetahs in the wild. “We want children to know that cheetahs are in danger,” said Steve. “It is important to protect their living places.” 11．Why are cheetahs and other wild cats in danger of dying out? A．Because they have few places to live and people hunt them. B．Because they are easy to be ill. C．Because they have nothing to eat. D．Because people send them into the zoo. 12．Which of the following is TRUE about cheetahs? A．Most cheetahs live in Africa. B．They are the world’s fastest animals. C．They are in danger because of the weather. D．There are about 100 000 of them in the wild now. 13．What does the underlined word “They” here refer to? A．The workers. B．The scientists. C．Mom cheetahs. D．Baby cheetahs. 14．How does the Saint Louis Zoo in Missouri help cheetahs? A．By raising baby cheetahs. B．By making laws to keep them safe. C．By sending baby cheetahs into the wild. D．By building more and more houses for them. 15．What is the writer’s purpose? A．To tell us the number of cheetahs. B．To tell us about a zoo with cheetahs. C．To tell us the situation about cheetahs. D．To encourage us to do something for the zoo. 【答案】11．A 12．A 13．D 14．A 15．C 【导语】本文主要讲猎豹等动物处境危险，科学家及动物园正在想办法保护它们。 11．细节理解题。根据“Cheetahs (猎豹) and other wild cats (大型猫科动物) are in danger of dying out because they have few places to live and people hunt (猎杀) them.”可知，猎豹和其它大型猫科动物有灭绝的危险，是因为它们几乎没有地方住，人们也在猎杀它们。故选A。 12．细节理解题。根据“Most cheetahs live in Africa.”可知大部分猎豹居住在非洲，A项正确，故选A。 13．词义猜测题。根据“‘The babies do well,’ the zoo’s worker, Steve, said. ‘They are very active and playing with each other or with their mom.’”可知是猎豹宝宝们很活跃，它们一起玩或者和妈妈一起玩。故“they”指猎豹宝宝。故选D。 14．细节理解题。根据“By raising baby cheetahs, the zoo is working to save cheetahs from dying out.”可知动物园是通过抚养猎豹宝宝来帮助猎豹的。故选A。 15．推理判断题。本文主要讲猎豹等动物处境危险及动物园目前所做的保护猎豹的事情，C项“告诉我们有关猎豹的情况”符合。故选C。 B Whales are beautiful and interesting animals on the earth. Are they fish? In fact, they aren’t fish. 16 It’s amazing to think how big whales are. 17 They are more than 30 meters long and weigh about 80 tons each. They are heavier than 24 elephants. A new baby whale weighs as much as a big elephant. The blue whale also has the largest heart in the world. 18 Whales feed on sea life. Some whales eat seals and fish. Some eat plants. Some whales have teeth, while others don’t. 19 So they often jump out of water. Beaches are not safe places for whales. They need to stay in the sea. For whales, the mistake of landing on beaches is dangerous. 20 Some people may catch whales for meat, fat and oil. Whale parts are sold to makes things like candles and soap. A．So they can’t swim.

A giant panda can grow up to 1.5 meters long and weigh up to 160 kg. People think the giant panda is very lovely. So it is not surprising that the World Wide Fund for Nature chose the giant panda as its symbol. The WWF tells people about animals that are in danger and raises money to save them. The giant panda only lives in the wild in China. In the early 1980s, there were only 1,000 left in the wild. The main reason why pandas are endangered is that the area where panda can live has become smaller. The WWF works to help giant pandas in the wild in many ways. One of the ways is to increase the size of panda reserves (自然保护区). Some reserves need to be joined together by planting bamboo between them to make “corridors”(走廊). These are paths that lead from one reserve to another. No one may harm the pandas in these areas. The corridors let pandas move from one habitat (栖息地) to another to look for food. ①People are working very hard to make sure the giant panda does not die out. 阅读以上材料，完成以下任务。 任务一：回答问题。 21．How long and heavy can a giant panda grow to be? 22．Why are the giant pandas endangered? 任务二：列举一个世界自然基金会帮助野生大熊猫的方法。(英文列举) 23．                                 任务三：根据短文内容，补全句子。 24．The corridors let pandas move from one habitat to another to .        任务四：翻译句子。 25．将文中①处画线句子翻译成汉语。 【答案】21．It can grow up to 1.5 meters long and weigh up to 160 kg. 22．Because the area where panda can live has become smaller. 23．To increase the size of panda reserves. 24．look for food 25．人们正在努力，以确保大熊猫不会灭绝。 【导语】本文是一篇说明文。主要介绍了大熊猫的现状和世界自然基金会保护大熊猫的行动。 21．根据“A giant panda can grow up to 1.5 meters long and weigh up to 160 kg.”可知，大熊猫可以长到1.5米高，体重可达160公斤。故填It can grow up to 1.5 meters long and weigh up to 160 kg. 22．根据“The main reason why pandas are endangered is that the area where panda can live has become smaller.”可知，熊猫濒临灭绝的主要原因是熊猫可以生活的区域变小了。故填Because the area where panda can live has become smaller. 23．根据“One of the ways is to increase the size of panda reserves (自然保护区).”可知，世界自然基金会帮助野生大熊猫的其中一个方法是增加熊猫保护区的规模。故填To increase the size of panda reserves. 24．根据“The corridors let pandas move from one habitat (栖息地) to another to look for food.”可知，这些走廊让熊猫从一个栖息地移动到另一个栖息地寻找食物。故填look for food。 25．people“人们”；are working very hard“正在努力”，是现在进行时；to make sure“为了确保”，不定式表目的；the giant panda does not die out是宾语从句，the giant panda“大熊猫”；does not“不”。表示否定；die out“灭绝”。故填：人们正在努力，以确保大熊猫不会灭绝。 四、短文填空 阅读下面短文，在空白处填入一个适当的单词或括号内单词的正确形式。 The panda is one of the best-known animals in the world.
