From high mountains to deep oceans, from small 1 (insect) to large animals, every living thing plays 2 important role in the natural world.

It gives us everything we need, like clean air, fresh water. and delicious food. 1 We cut down too many trees to build houses and make paper. As a result, many animals lose their homes. 2 The water becomes so polluted that fish can’t live in it. And cars and factories send out harmful gases, making the air dirty. We are making nature sick. These problems are bad for both nature and us. 3 Clean air and water are necessary for our health. If we keep polluting the environment, we will get sick easily. Besides, beautiful natural places, like mountains and forests. make our lives more interesting. They are great places for us to relax and have fun. So we must take action to protect nature. To make things better, we can do many small but useful things. First, we should save water. Turn off the tap when we brush our teeth. Second, plant more trees. They can make the air clean. Finally, use less plastic. 4 We can also use a cup instead of a plastic bottle. If we all do these things, we can live in harmony with nature and make the world a better place. A．It’s very important to live in harmony (和谐) with nature. B．We can take our own bags when shopping. C．Also, factories pour dirty water into rivers and lakes. D．We should also save electricity at home. E．However, these years, we haven’t treated nature very well. 七、阅读理解。 Do you know how everything in nature is connected (连接)? It's like a big team where everyone has a job. Small changes can cause (引起) big problems. Here are some real-life stories about the balance (平衡) of nature. Not many years ago, some farmers were worried because hawks (鹰) took many of their chickens, so the farmers killed many hawks. They no longer (不再) had to worry about their chickens. But then they had new worries. Mice ate the farmers' food. How did this happen? Hawks ate not only chickens but also mice. There are more mice than chickens. But the farmers did not know this. When they killed many hawks, they changed the balance of nature. Changing the balance is bad for nature. Sometimes when people move into a new place, they often cut down many plants. Some of these plants are food for animals. If the animals cannot find food to eat, they will die or have to leave the place. Here is another example. In a place of the United States, the giraffes there ate a kind of rose. The lions there ate the giraffes. The number of giraffes, lions and roses did not change much if people kept things as they were. But people killed many lions to protect the giraffes. Soon there were so many giraffes that they ate up all the roses. Then the giraffes began to eat leaves of young trees. These trees were important to people. So people thought of ways to protect trees. Now the giraffes had nothing to eat, and many of them died. This was another lesson from nature. Nature is like a huge family where everything depends on each other. We should take good care of nature and keep it balanced. If we do, everything in nature can live happily together! 1．How does the writer start the passage? A．By giving a fact. B．By asking a question. C．By giving an opinion.

C．The balance of nature will become better. D．Animals may die or leave because of no food. 4．Which one shows the right relation (关系) of giraffes, lions, roses and trees? A．Lions → Giraffes → Roses & Trees B．Roses → Giraffes → Lions C．Lions → Roses → Giraffes D．Trees → Giraffes → Roses & Lions 5．Why does the writer tell us these stories? A．To share funny animal stories. B．To teach us how to protect plants. C．To make us feel sorry for the killed animals. D．To show us the importance of keeping nature in balance. 八、完形填空。 Pandas are in danger. There are only about 1, 600 pandas 1 the wild today. Zoos and research centres are 2 about 340 pandas.

It sits at an altitude (海拔) of about 3,100 meters and covers an area of about 105 square kilometers. It is rich in salt with a heavy salt bed close to the lake surface (表面). That makes the lake a main source (来源) of salt in our country. When the weather is clear, the lake offers beautiful reflections (影像) of the blue sky. That is why people call it “sky mirror (镜子)”. Because of its wonderful views, people see the lake as one of the “must-go” places in China. The beautiful sunrise and sunset views are the most attractive (迷人的). Every July, large numbers of visitors begin to crowd to (涌入) Chaka Salt Lake. And the situation usually lasts until the end of August. Because they just don’t want to miss the best time to go there. It is believed that with the summer breeze (微风), breathing in the salty air is especially good for lungs (肺). If you want to go on a trip to the lake, the following tips may be helpful. ◆ Do not eat the salt in the lake directly. ◆ Wear sunglasses and a hat because of the strong sunshine. ◆ You can’t stop taking photos, so you’d better take your camera with you. ◆ Prepare some medicine for the weak and the elderly to deal with altitude sickness. Travelling to such a beautiful world of salt with snowy mountains and green grass around, you will feel like you are in a fairyland. 1．Where does Chaka Salt Lake lie? _____________________________________________________________________________ 2．What’s the area of Chaka Salt Lake? _____________________________________________________________________________ 3．Why do people see Chaka Salt Lake as one of the “must-go” places in China? _____________________________________________________________________________ 4．Why should people prepare medicine for the weak and the elderly? _____________________________________________________________________________ $ Unit 5 Amazing nature 课时4 Developing ideas(listening and speaking) 分层作业 参考答案 一、单词默写。 【答案】1.exhibition 2.lungfish 3.lung 4.develop 5.land 二、词组默写。 【答案】1.

It's like a big team where everyone has a job. Small changes can cause (引起) big problems. Here are some real-life stories about the balance (平衡) of nature. Not many years ago, some farmers were worried because hawks (鹰) took many of their chickens, so the farmers killed many hawks. They no longer (不再) had to worry about their chickens. But then they had new worries. Mice ate the farmers' food. How did this happen? Hawks ate not only chickens but also mice. There are more mice than chickens. But the farmers did not know this. When they killed many hawks, they changed the balance of nature. Changing the balance is bad for nature. Sometimes when people move into a new place, they often cut down many plants. Some of these plants are food for animals. If the animals cannot find food to eat, they will die or have to leave the place. Here is another example. In a place of the United States, the giraffes there ate a kind of rose. The lions there ate the giraffes. The number of giraffes, lions and roses did not change much if people kept things as they were. But people killed many lions to protect the giraffes. Soon there were so many giraffes that they ate up all the roses. Then the giraffes began to eat leaves of young trees. These trees were important to people. So people thought of ways to protect trees. Now the giraffes had nothing to eat, and many of them died. This was another lesson from nature. Nature is like a huge family where everything depends on each other. We should take good care of nature and keep it balanced. If we do, everything in nature can live happily together! 1．How does the writer start the passage? A．By giving a fact. B．By asking a question. C．By giving an opinion.

A．To share funny animal stories. B．To teach us how to protect plants. C．To make us feel sorry for the killed animals. D．To show us the importance of keeping nature in balance. 【答案】1．B 2．D 3．D 4．A 5．D 【导语】本文是一篇说明文，通过两个真实案例讲述了自然界万物相互联系、相互制约的关系，强调了保持自然平衡的重要性。 1．根据文章开头“Do you know how everything in nature is connected?…Here are some real-life stories about the balance of nature.”可知，作者以提问的方式引出下文。 2．根据第二段“Not many years ago, some farmers were worried because hawks took many of their chickens, so the farmers killed many hawks.

The lions there ate the giraffes. …So people thought of ways to protect trees. Now the giraffes had nothing to eat, and many of them died.”可知，三者的关系是Lions→Giraffes→Roses & Trees。 5．根据全文及最后一段“Nature is like a huge family where everything depends on each other. We should take good care of nature and keep it balanced.”可知，作者讲述这些故事是为了说明保持自然平衡的重要性。 八、完形填空。 Pandas are in danger. There are only about 1, 600 pandas 1 the wild today.
