The number of pandas 8 (get) smaller and smaller. One of the main reasons is that people are cutting down too many bamboo trees. 9 we want to keep seeing these lovely animals, we should protect their living environment and plant more bamboo trees. We should also stop 10 (hunt) them. Let’s work together to make a better home for pandas. 六.阅读填空 If you could be any animal, what would you be? David Attenborough in a sloth hanging in the tree Nueva School says his favourite animal is sloth because it is always lazy and it needs to do nothing. 1 . Sloths usually move up to 40 metres a day. 2 And they don’t give sloths much energy (能量) to move quickly. Sloths also have the slowest metabolism (新陈代谢) among mammals (哺乳动物). It could take them about 30 days to take in (吸收) one leaf! 3 Sloths spend up to 90% of their lives hanging upside down in trees—mostly sleeping. A sloth sleeps between 15 and 20 hours each day. 4 Don’t worry. That’s okay for them to fall from 30 metres. Do you know that they may have a fall from trees every week? And if they fall in water, that’s okay too. Sloths are good swimmers, and they move faster in water than they do in trees! 5 Many different kinds of algae (藻类) live in a sloth’s fur. Because it’s warm and sloths don’t move much. Interestingly, algae also gives the sloth’s fur a green colour—the same colour as the trees to keep the sloths safe. A．Sloths’ fur is a home for others. B．There are other fun things about sloths. C．Sometimes they fall from the high trees. D．They move slowly because they mostly eat leaves. E．He knows that sloths are the slowest-moving mammals. 七、阅读理解。 A There are many amazing animals in the world. Have you ever been to a zoo to see different kinds of animals? Zoos are great places for people to learn about animals. You can see lions, tigers, elephants, monkeys and many other animals there. Lions are known as the “kings of the jungle”. They are very strong and powerful. They have sharp teeth and claws, which help them catch their food. Lions usually live in groups. They hunt together and share their food. Tigers are also very powerful animals. They are good at swimming and can swim across rivers easily. Tigers have beautiful stripes on their bodies. Each tiger’s stripes are unique, just like human fingerprints. Elephants are the largest land animals. They have long trunks that they use to pick up food, drink water and even to greet other elephants. Elephants are very intelligent animals. They have a good memory and can remember places where they found food and water. Monkeys are very lively and clever animals. They like to climb trees and jump from one branch to another. Monkeys have long tails that help them keep balance. They are also very social animals and live in large groups. Zoos not only let us see these wonderful animals but also play an important role in protecting them. Many animals in zoos are from endangered species. Zoos work hard to breed these animals and help increase their numbers. 1．This passage is most probably taken from ______. A．a storybook B．a science magazine C．a travel guide D．a history book 2．According to the passage, which of the following is TRUE about lions? A．They live alone. B．They have no sharp teeth. C．They hunt together. D．They are the largest animals. 3．What can we infer from the passage? A．All animals in zoos are from endangered species. B．Tigers’ stripes are the same as each other. C．Elephants can use their trunks to do many things. D．Monkeys have long tails just for fun. 4．What is the main idea of the passage? A．To tell us how to protect animals. B．To introduce different animals in zoos and their features. C．To show the importance of zoos. D．To describe the life of animals in the wild. B Do you know koalas? They are very cute animals from Australia. Koalas look like small bears. They have thick, grey or brown fur. Their ears are big and round, and their eyes are small. They have sharp claws which help them climb trees easily. Koalas spend most of their time in trees. They sleep for about 18~22 hours a day. When they are awake, they spend a lot of time eating. Their main food is eucalyptus leaves. Eucalyptus leaves are not very nutritious, but koalas have a special digestive system that allows them to get enough nutrients from these leaves. Koalas are very slow-moving animals. They don’t move quickly like monkeys. But this slow movement helps them save energy because they don’t need to search for food actively. They just stay in the trees and wait for the leaves around them. However, koalas are facing some problems. The loss of their habitat due to deforestation is a big threat to them. People are cutting down trees where koalas live, so they have fewer places to live and less food to eat. We should do something to protect these lovely animals. 5．According to the passage, koalas mainly eat ______. A．fruits B．grass C．eucalyptus leaves D．small insects 6．The underlined word “deforestation” in the passage means “______” in Chinese. A．森林火灾 B．植树造林 C．森林砍伐 D．森林保护 7．What is the structure of the passage? A．①/②③/④ B．①②/③/④ C．①/②/③④ D．①②③/④ 8．What’s the writer’s attitude towards koalas? A．Indifferent. B．Worried. C．Angry.

Pandas once lived in a few parts of Asia, including (包括) Vietnam and Burma, but now they live only in some parts of China. Pandas spend about 12 hours every day eating. They mainly eat bamboo. And they always travel between different places to find fresh bamboo. Also, they eat fruit, other plants and some fish. Pandas usually live in cold and wet places. Their black-and-white coats keep them warm. Pandas are very good at climbing. If people or animals run after them, they will climb up the nearest tree very quickly. Their good hearing also helps them to avoid animals who want to eat them. There are about 1,900 wild pandas left in China. Their main problem is that their living places are becoming smaller and smaller. China has realized this problem and is trying her best to do things for pandas. Now, China has set up some special places which are big enough for pandas to live in. 1．Do pandas live a solitary life? ___________________________________________ 2．How long do pandas spend eating every day? _____________________________________________ 3．Where do pandas usually live? ___________________________________________ 4．What will a panda do if an animal runs after it? ___________________________________________ 5．What’s the main problem for wild pandas? ___________________________________________ 十、书面表达 大熊猫和小熊猫一样都是我国国宝级的动物。2016 年世界自然保护联盟将大熊猫从 “濒危” 等级下调为 “易危”，在 2024 年 11 月全球熊猫伙伴大会上，我国大熊猫保护的 “成绩单” 也令世界瞩目。虽然大熊猫不是濒危物种了，但野生大熊猫依旧需要我们的保护。请你根据以下思维导图的提示，用英语写一篇文章。 参考词汇：nature reserve 自然保护区 1 / 7 学科网（北京）股份有限公司 $ Unit 1 Animal friends! 课时4 Section B (1a-2b) 分层作业 核心知识速记 01基础达标 02能力提升 03拓展培优 04思维进阶 词汇 fox n. 狐狸 giraffe n.长颈鹿 eagle n.雕；鹰 wolf n. 狼 penguin n. 企鹅 care n.照顾；护理 v.关心；在乎 take care of 照顾，处理 句型 --What’s your favorite animal? --I like...best. --Why do you like...? --Because they are. 一、单词默写。 1. _______ [ˈkʌltʃə(r)]n. 文化 2. ________ [haʊˈevə(r)] adv. 然而；不过 3. __________ [ˈdeɪndʒə(r)] n. 危险 4. ________ [ˈfɒrɪst] n. 森林 5. ________ [ˈfrendli] adj. 友好的 6. _______ [blaɪnd] adj.瞎的；失明的 7. ________ [ˈhɪərɪŋ] 听力；听觉 8. ________ [ˈswɪmə(r)] n. 游泳者 1.culture 2. however 3. danger 4. forest 5. friendly 6. blind 7. hearing 8.swimmer 二、词组默写。 1. 相互 _______________________ 2. 照顾 _______________________ 3. 处于危险之中 _______________________ 4. 砍伐；减少 _______________________ 5.太多 _______________________ 6. 由…制成的 _______________________ 7. 一点也不_______________________ 8. 好运的象征 _______________________ 9. 与…大不相同 _______________________ 10. 给出你的原因 _______________________ 11. 庆祝泰国大象节_______________________ 12. 熟悉某地的环境_______________________ 2. one another 2. look after 3.in danger 4. cut down 5. too many 6. be made of 7.not…at all 8.a symbol of good luck 9. be very different from 10. give your reasons 11. celebrate Tai Elephant Day 12. find one’s way round 三、单词拼写 1．There are many different kinds of (animal) in the zoo. 2．I like giraffes because they have long necks and look (amaze). 3．Penguins can’t fly, but they are good at (swim). 4．Tigers are (danger) animals, so we should keep away from them. 5．The baby monkeys (look) very lovely.

You have to keep the room clean. 3．熊猫没有足够的食物吃，因为人们砍倒了太多竹子。 Pandas don’t have enough food to eat, because people too much bamboo. 4．许多野生动物现在处于危险之中。我们应该保护它们。 Many wild animals are now.

Their black-and-white coats keep them warm. Pandas are very good at climbing. If people or animals run after them, they will climb up the nearest tree very quickly. Their good hearing also helps them to avoid animals who want to eat them. There are about 1,900 wild pandas left in China. Their main problem is that their living places are becoming smaller and smaller. China has realized this problem and is trying her best to do things for pandas.
