英语人教版新教材八年级上册单元测试题（带答案） Unit 4 Amazing Plants and Animals 一、阅读理解（20小题，共40分） A Why Are Onions Amazing? Onions are round and come in different colours like white, yellow and red. They have a strong smell and taste. When we cut them, they can make us cry. Many people enjoy eating them, but they are more than tasty. They are useful as well. High in vitamins, onions give great benefits to our bodies and help us stay healthy. ▲ A special plant called the corpse flower(巨花魔芋) is native to Indonesia, but can be seen in botanical gardens in Australia. It is one of the smelliest(最臭的) flowers in the world. You can see a flower like this only once every seven to ten years. It does not smell sweet but like rotten(腐烂的) meat. Why? Because it wants to draw small insects to help it bring the pollen to other places.  How Do Plants Work? It's a quarter past seven. Here's Worker No. 55 in its green clothes. It works in the leaves. It collects sunlight and carbon dioxide (C) during the day. Workers from the root give it water(O). Then the plant will make sugar, which is useful. It also makes oxygen().

The corpse flower is the most smelly plant in the world. C. The “Worker No.55” in the leaves is a true worker. 5.In which part of a newspaper can we read the passage? A. Food. B. Travel. C. Nature. B Nature is amazing! Look closely at the world of insects, and you will find many interesting facts. Let's take butterflies as an example. They have beautiful, colourful wings and strong, fantastic flying skills. On summer days, you always see them flying freely over flower gardens and wild fields. But do you know how a butterfly grows? It is one of the most fantastic wonders(奇观)of nature. First, a butterfly lays a small egg on a leaf of a plant. It's hard to believe that the egg will become something completely different in a few days. It becomes a walking insect called a caterpillar. It now has legs, eyes and a large body. A new life begins. The caterpillar can eat, walk and see. But it is still not a butterfly. After the caterpillar grows big, it makes a cover to protect itself. It stays inside this soft cover and goes to sleep. We call it the “pupa” stage(“成蛹”阶段). After some days, the cover breaks open. A wet and weak(脆弱的) butterfly comes out. It has six legs, a mouth, eyes and wings. Soon, the wings become dry and strong. The beautiful butterfly spreads(伸展) its wings and flies away. A few weeks later, this butterfly lays its eggs, and the life cycle starts again. This is just one example of the wonders of nature. Look around the natural world, and you will learn many truly amazing things. 6.What can we know about butterflies from Paragraph 1? A. Butterflies are a kind of insects. B.

Most animals have homes too.Some animals live under the ground. The woodchuck（土拨鼠）lives in the holes（洞穴）under the ground. His home has two doors. If someone comes in through one door, he will go out through the other door. Some birds live in the holes in the trees. They come out for food during the day and go back to sleep at night. But most birds live in the trees. Itˈs very interesting that turtles（龟）usually carry their homes on their backs. Bees always work hard to make their homes. Cats, dogs and some other pets live in people's homes. And we can see many kinds of animals in the zoo, so the zoo is also home to animals. 11.Where do the woodchucks live under the ground? A.

D There are about 300 kinds of sharks in the world, including 160 kinds in China. All sharks are meat-eaters (食肉动物)。Most sharks have four to six rows (排) of teeth. When a sharkˈs tooth falls out, another tooth in the back row will move up to take its place. Sharks do not have ears, but they can “feel” sounds and movements in the water. Any sound or movement makes the water vibrate (振动). This helps sharks find food. Sharks also find food with their large eyes. Most sharks see best in poor light, so they always go to get food in the early morning, in the evening, or at night. Sharks live in every ocean on earth, and most sharks live in warm water. They can help keep the seas clean by eating sick fish and sea animals. Scientists want to learn more about sharks for other reasons. For example, cancer (癌症) is common in many animals, including humans, but sharks never get cancer. Maybe the information can be a great help. Many people are afraid of sharks, but most sharks, except a few like the great white sharks, wonˈt hunt for humans. People kill sharks mainly for their skin (皮), meat, oil (油), and teeth to sell. So some kinds of sharks are now in danger. We should save them. 16.What's so special about sharksˈ teeth from Paragraph 2? A. They help them eat meat faster. B. They have spare ones for fallen teeth. C. They let sharks be the best hunters in the ocean. 17.Why is the shark's ability to feel vibrations in water important? A. It helps them to find food. B. It helps them communicate better. C. It reminds them of dangerous things. 18.Why are scientists interested in sharksˈ being cancer-free (免于患癌症)? A. To make sharks live longer. B. To know how they keep healthy. C. To help find treatment for human illness. 19.What is the main reason for people killing sharks? A. Because people can get money from them. B. Because people think sharks are dangerous. C. Because people want to protect the ecosystem balance. 20.What is probably talked about next? A. Dangers sharks face. B. Actions to protect sharks. C. Reasons for saving sharks. 二、补全对话（5小题，共10分） A: Hi, Dale! Do you like animals? B: Yes, I do.    (21)    A: That's true. So, which animal do you like best?

However, they are thriving (繁荣) once again in the New Forest, in the south of England. People call the birds "phantoms (幽灵) of the forest". They nearly disappeared in the UK. Forests are home to goshawks, but people cut down too many trees so they lost their home. In 2002, a pair of goshawks made their nest (巢) in the New Forest for the first time in more than 120 years. Since then, a team of scientists has been closely watching the goshawks. The team looks after around 1,500 forests and woodlands. The team says that the New Forest is now a good place for goshawks to live in. Later, they found 45 goshawk pairs. Scientists used a camera to watch one pair with three babies. They found that the birds ate different foods, such as squirrels, small birds, and other small animals. They also found how the father bird protected his babies from the hot sun by using his big wings. The goshawk is at the top of the food chain (食物链). Usually, other animals don’t attack (袭击) them. Because of this, these birds tell us a lot about the health of this forest and the situation of wild animals in it. 46.Where is the New Forest? ________________________________________________________________ 47.Why did goshawks lose their home in the UK? ________________________________________________________________ 48.How many forests and woodlands does the team look after? ________________________________________________________________ 49.Who protected the babies from the hot sun, the father bird or the mother bird? ________________________________________________________________ 50.What can these goshawks tell us about? ________________________________________________________________ 六、书面表达（1小题，共20分） 某英文报社正在征集以保护动植物为题材的文章。请你根据以下要点和要求写一篇短文,向该报社投稿。 要点:(1).野生动植物的现状;(2).造成许多野生动植物濒临灭绝的原因;(3).保护野生动植物的建议(至少三条)。 要求:(1).文中不能出现真实校名和姓名;(2).词数80左右,开头已给出,不计入总词数。 Many kinds of plants and animals are in danger now.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     ​​​​ 答案 一、1~5.B、A、B、A、C 6~10.A、B、C、C、A 11~15.A、B、A、B、C 16~20.B、A、C、A、B 二、21~25.D、A、B、F、E 三、26~35.A、A、B、A、D、B、D、A、C、B 四、36.a 37.because 38.connected 39.eating 40.especially 41.in 42.importance 43.bags 44.your 45.happiness 五、46.The New Forest/It is in the south of England. /In the south of England. 47.Because people cut down too many trees. 48.The team/It looks after around 1,500 forests and woodlands. / Around 1,500. 49.The father bird. 50.These goshawks/They can tell us about the health of this forest and the situation of wild animals in it. /The health of this forest and the situation of wild animals in it. 六、范文 Many kinds of plants and animals are in danger now. We should try our best to protect them. More and more plants and animals are dying out because they lose their living places or can't find enough food. People cut down trees or kill animals to make money. Some factories pollute the rivers and lakes. That's the reason why plants and animals are in danger. I think we should do something now. We should plant more trees, stop killing animals and ask some factories not to pollute water to provide a better environment for them. 第1页，共1页 学科网（北京）股份有限公司 $
