中考复习科普环保类专项练习 一、阅读理解 When you watch TV programs about wild animals, it is surprising to see how an antelope (羚羊) can run away from a strong lion. In the wilderness, everyone has his own way to protect himself. Even plants have their own ways to fight off enemies. Over millions of years, plants have developed their own defense system (防卫系统). Chemicals are fantastically used by plants to survive (幸存). By making their leaves, flowers, roots and fruits poisonous (有毒的) to enemies, plants can fight back. One such plant is the Golden Wattle tree. The British scientist David Cameron has found when an animal eats the tree’s leaves, the amount (数量) of poison increases in the other leaves. “It’s like the injured leaves telephoning the others to fight together against the enemy,” he said. The tree also sends defense messages to neighboring plants by giving out a special smell. Golden Wattle trees in the nearby 45 meters will get the message and produce more poison within 10 minutes. Now, if an enemy eats too many of the trees’ leaves, he will die. Every kind of plant or tree is good at producing a special set of chemicals. Herbivores, like rabbits, can safely eat the leaves of one tree, but they may be poisoned by its neighbor. In this way, plants have not only developed their own defense system, but also shared it with others. This makes it impossible for a single animal to destroy even a small area of forest. 1．From the first 2 paragraphs, we can learn that _________. A. plants can do nothing against their enemies B. chemicals are quite useful for plants to survive C. an antelope can always run away from a strong lion D. leaves, roots, flowers and fruits of plants are poisonous 2．If animals eat one Golden Wattle tree’s leaves, the tree can________. A. kill the animals with a special smell B. tell other trees to come to protect it C. warn other trees against the animals on the phone D. send defense messages to the neighboring plants 3．The underlined word “herbivores” in the 5th paragraph probably means animals which _____. A ． produce poison B ．live on small animals C ． like to eat rabbits D．feed on plants or grass 4．The last paragraph of the passage suggests that this kind of defense system is ________. A ． bad for animals B．good for forests C．helpful to some animals D．harmful to forests 5．The passage is mainly about __________. A．the examples of protecting forests B．the balance between animals and plants C．the ways of plants fighting against enemies D．the relationship between lions and antelopes Qi Haoran, a Junior 1 student, was quite busy over the past winter vacation – and not just with homework. Qi, together with 10 other classmates made a volunteer group to call on people to join the Clean Your Plate Campaign (“光盘行动”). The 11 students went to many restaurants and told people the importance of saving food.“Excuse me, do you know that 950 million people around the world still haven’t got enough to eat? Please don’t waste food.” They would say this kind of thing hundreds of times every day. The Clean Your Plate Campaign began on the Internet in January. It calls on people to reduce food waste. China in these years had serious problems with wasted food. CCTV reported in January that the food Chinese people waste every year is enough to feed 200 million people for a year. Chinese people are well known for being hospitable (好客的) and generous（大 方的）.Many even feel that they lose face if their guests have eaten all the food. Luckily, the campaign has got the support of many. In a restaurant in Xinjiang, the owner give the guests who have eaten all that they ordered a sticker (贴花).People can enjoy a free meal when they have 10 stickers. More than 750 restaurants in Beijing have begun to offer smaller dishes and encourage their guests to take leftovers (剩 饭剩菜) home. To reduce food waste is a big task, and it needs time. It’s important that everyone does their bit, just like Qi. Did you finish your meals today? 根据短文内容，从 A、B、C、D 四个选项中选择最恰当的答案。 6．What did the 11 students do in the winter vacation? A. The helped each other with homework. B. They opened a restaurant together. C. They volunteered for a campaign. D.

It gave stickers to the guests who ordered small dishes. D. It encouraged customers to take leftovers home. In nature, you may see many insects (昆虫）and animals of different colors. Have you ever wondered why? Locusts are super delicious food for birds, but it is not always an easy job for birds to catch them. It is neither because locusts are good jumpers or runners nor because they are smarter than their enemies. The reason is that the colors of locusts change with the colors of crops(庄稼). When crops are young, locusts look green. But when autumn comes, locusts change to the yellow and brown color as crops do. Brown bears, tigers and other animals move quietly through forests. They can’t be seen easily by their enemies. This is because they have colors similar to the trees. For the same reason, polar bears that live on a land of snow and ice are white. Butterflies and bees living among the flowers are colorful like flowers. Soil insects are mostly dark-colored and they live under the soil(土壤） in a dark and wet environment. However, insects with colors different from plants can easily be found and eaten by others. So in order to survive, they have to hide themselves in the daytime and appear only at night. Have you ever noticed some even stranger acts? The ink fish in the sea can send out some very black ink when it faces danger. As the ink spreads over , its enemies will find themselves suddenly in a dark world. At the same time the ink fish immediately swims away. That is how it keeps itself safe though it is not strong at all. 11．It is not easy for birds to catch locusts because____________. A .locusts are good runners B. locusts can jump very high C. locusts are smarter than birds D. locusts can change their color 12．According to the passage, most soil insects_________ A. do not have bright colors B. change their colors with the soil C. do not live in a dark and wet environment D. Eat colorful insects like butterflies and bees 13．What’s the meaning of the underlined word”survive” in the passage? A. 繁殖 B. 产卵 C. 觅食 D. 生存 14．The ink fish _______so that its enemies will not see it? A. changes its color B. makes the water around it black C. appears only at night D. hides itself in the sea rocks 15．What is the main idea of this passage? A. Some insects and animals have different skills. B. Some insects and animals are clever than we think. C. Some insects and animals use colors to protect themselves. D. Some insects and animals can get used to the environment easily. Many children think mobile phones are cool. They come in fun colors and let you talk with friends anytime and anywhere. In the U.S., more than 90 million people use mobile phones. Many of these people are children. For children, mobile phones are more than phone calls. They are fashionable. Most mobile phone users don’t think about the health problems caused(引起) by mobile phones. Some scientists say that mobile phones give off radiation(辐射) that might be bad for the users. One newest study shows that mobile phone radiation might raise(增加) a person’s chance of getting some kinds of cancer(癌症). Other scientists say mobile phones don’t’ threaten people’s health. They say that they have not found any link(联系) between phone use and cancer. Scientists say that people can protect (保护) themselves from mobile phone radiation. One way is to use a headset(耳机). Or people can make shorter call. 16．Many children like mobile phones because they think mobile phones are _________.

Both B and C This March, the H7N9 virus (病毒) hit Shanghai, Anhui, Jiangsu, Zhejiang and so on. It seemed that most people who were infected(被感染) with H7N9 had the common flu. Some people suffered from a fever or a cough. Don’t be afraid—it’s not easy to be infected with the virus. Here is some advice to help you protect yourself when it comes. Wash your hands. You need to wash your hands with soap and hot water before you eat, after you use the toilet, and after you touch animals, because your hands may carry viruses. Cover your nose and mouth. When someone sneezes(打喷嚏) or coughs, flu viruses can travel as far as one meter through the air, so you’d better stand a proper distance (距离) while talking to someone who has a cold. And always cover your mouth and nose with a piece of paper when you sneeze or cough, and then clean your hands. Wear a mask(口罩). Some doctors say that masks can stop the flu as much as 80%, but if you don’t wash your hands often, it’s no use wearing a mask. And it’s necessary to wear the mask in the groups of people. Do sports often. Exercises will help make your body strong enough to resist the virus. 21．When did the H7N9 virus hit Shanghai? A．In March, 2013. B．In May, 2013. C．In March, 2012. 22．Which of the following is TRUE according to the passage? A．Some people who were infected with the H7N9 virus had a toothache. B．You should cover your mouth and nose with a piece of paper when you sneeze or cough. C．Some doctors say that masks can stop the flu as much as 100%. 23．How many ways to stop the virus are mentioned in the passage? A．Three. B．Four. C．Five. 24．What does the underlined word “resist ” mean in Chinese? A．抵抗 B．传播 C．感染 25．What’s the main idea of this passage? A．It tells us how to wash hands. B．It tells us why we should use masks. C．It gives us some advice on how to protect ourselves when the H7N9 virus comes. Carrots(胡萝卜) are grown on farms and in small family gardens all over the world. They are easy to plant and easy to harvest(收获). They have a good taste. When people think about carrots, they usually think they are a kind of long, thin, orange-colored vegetable. In fact, carrots are in many different sizes and shapes. And not all carrots are orange. Carrots should be grown in a field that does not have water for a long time. The earth also should not be too hard. To prepare your carrot garden, dig up the earth and turn it over(翻土). Weather, soil condition(土壤状况), and time affect(影响) the taste of carrots. Warm days and cool nights are the best time to grow great delicious carrots. The best way to decide if a carrot is ready to be harvested is by its color. Usually, the brighter the color is, the better the taste is. Most people do not know that carrots can be grown during the winter months. If the winter is not cold enough to freeze the ground, you can grow carrots the same way as you do during the summer months. Carrots are prepared and eaten in many different ways. They are cut into thin pieces and cooked with other vegetables or meat. Or, they are washed, and eaten just as they come out of the ground. 26．Carrots are easy to plant but hard to harvest. 27．Carrots should be grown in a field without water for a long time. 28．The best way to decide if a carrot is ready to be harvested is by its size. 29．Everyone knows that carrots can be grown during the winter months. 30．We can prepare and eat carrots in many different ways. Hi Brad, It’s good to hear from you again. I find that I’m not good at writing compositions. It’s hard for me to prepare the form of a composition and organize sentences. ① Could you tell me how to deal with this problem? I would really appreciate if you offer me some good methods. Best wishes, Cindy Hi Cindy, A composition is really a story and any story is told to an audience. There is a form for this and it is in three parts. First, tell them(the audience) what you are going to tell them. Then tell them, and finally tell them what you told them. Parts one and three are short and most of the information is in part two. It works like this. Let’s say you are asked to write a 200-word composition about your visit to the Great Wall. You would begin with an opening sentence or two saying something like “The Great Wall of China is a national ②landmark that is famous around the world. I visited it last summer and I want to tell you about it.” That uses about 25 words to tell them what you are going to tell them. The second part would be about 150 words and would contain information about the Great Wall such as how long it is, when it was built, who built it and why, the fact that it is one of the seven wonders of the world and you would talk about how you felt and what you thought when you visited this national treasure. This is telling them. Finally, you would use about another 25 words to say something like “That was my first visit to the Great Wall and it was a very emotional experience to actually touch something so old and famous. ③每个中国人至少参观长城一次.I plan to go back whenever I can.” Here, you are telling them what you told them in the story and wrapping it all up into a neat package. This formula(惯例)works for both compositions and speeches and I think you will find it helps to organize your thoughts. I hope it’s helpful. Best wishes, Brad Franklin 31 ．将文中①处的画线部分翻译成汉 语： . 32．(A) 试写出文中②处画线部分 landmark 的汉语意思： . (B)下面有四个在文中出现的单词，请找出画线部分发音哪个与众不同? .

How I wish to _________ _________ you soon! 35 ． 用 英 语 回 答 问 题 ： What’s the main idea of the passage? . When you look up into the sky at night, have you ever felt that your eyes are playing tricks on (捉弄) you? It seems that the stars are moving all the time. Actually, there is nothing wrong with your eyes. This twinkling effect is called scintillation (交光). Scintillation happens because of air movements in the earth’s atmosphere (大气). Light is “bent (弯曲的)” when it travels through different parts of the earth’s atmosphere. As the air in the earth’s atmosphere is moving all the time, the light from the stars looks as if it is moving too. The same thing also happens to things on the ground. On a very hot and shiny day, if you look at the road, the image in the distance is not clear and things move slightly. You can also see the same effect if you drop a rock into water. The rock appears a little unclear under the moving water. This twinkling effect causes a lot of problems for astronomers (天文学家) since they cannot observe the stars clearly. A telescope (望远镜) was sent into space so that the air movements in the atmosphere could be avoided (避免). It took a long time to build the space telescope but finally in 1990, a huge space telescope called the Hubble Space Telescope was successfully sent into space. Since then, astronomers have many important observations that have helped people understand space better. 根据短文内容，选择最佳选项。 （10 分） 36．What happens to the light from the stars we see when the air in the earth’s atmosphere is moving?

The water becomes much polluted. D. The water does not move anymore. 39．The underlined word “observe” means “ ”. A. watch B. listen C. draw D. explain 40．Why is scintillation a problem for astronomers? A. The stars never stay still. B. It makes the stars too dark to see. C. It makes astronomers feel too hot to work. D. Astronomers cannot observe the stars clearly. Imagine the situation. You are driving along a desert or on a mountain. You have no idea where you are. You passed the last house two hours ago. Then your car breaks down. It is night and it is cold. You have no mobile phone. What do you do? Well, next time take a GPS with you. This invention may be able to help you. It is a device(装 置) which uses satellites (卫星) to find the user’s position(位置). It can find your position to within 20 metres. A GPS cannot start your car, but at least you will know where you are. GPS, which means Global Positioning System, is a small radio receiver. It looks like a mobile phone. You can hold it in your hand, or put in your pocket. It is sometimes put into a watch or a telephone. We also find GPS devices in cars, planes, or boats. Some of these devices have electronic maps, so you know where you are. For example, in a city they can tell you the name of the street. There are three parts to the Global Positioning System. The first part is the receiver. You can hold it in your hand, or have it fixed into your car, plane, etc. The second part is a group of satellites orbiting the Earth. The receiver contacts at least four of the satellites and calculates(计算) its position. The third part of the system is a network of ground stations. They are all over the world. They control the satellites and make sure they are working well. Some people think that in the future the GPS will be as common as the mobile. They are becoming cheaper and more and more accurate(精确的). There are also new uses for the GPS. Perhaps they will become like watches. Everyone will have one and you will never be lost again. 41．According to the passage, with the help of the GPS, people __________. A. can’t be lost in a new city B. can’t find their way in different countries C. can learn about the culture of an unknown place D. can spend the least time getting to another place 42．We can learn from the passage that ____________. A. there are three parts to the GPS B. a GPS can’t be put into a watch C. a GPS can help you start your car D. the GPS are becoming more and more expensive 43．The underlined word “They” in paragraph 3 means “____________”. A. Receivers B. GPS devices C. Satellites D. Ground stations 44．The passage is mainly about _______________. A. the history of the GPS B. the introduction of the GPS C. the shape of the GPS D. the three parts of the GPS 45．What can we infer(推断) from the passage? A. All GPS devices have electronic maps. B. People in many countries will use the GPS for free. C. The receiver of the GPS contacts at least five of the satellites. D. The GPS will become more and more common in everyday life. Many of us don’t pay much attention to the importance of eye care. It is said if you take care of your body, then you can surely be healthy. That is why our eyes should be given a lot of care. Natural eye care should be put in a number one place. There are several causes leading to poor eyesight like not enough food, genes （基因）and aging(老化). Televisions, computers and reading are also the causes of having poor eyesight. If you happen to work in front of the computer, it is best to take a break every once in a while. Something dirty can cause redness and they will make you feel uncomfortable. It is bad for your eyes, too. If this happens, the best way is to clean your eyes by using cold water. You must also try your best to protect your eyes from harmful things. For example, sunglasses are not just for fashion but they can also serve as a great way to protect your eyesight from UV rays. Eating healthy foods will do good to your eyesight. Remember that vitamins A, C and E are good for eyes. Try to eat food groups that have these vitamins. And you should do eye exercise protects your eyesight, too. If a person exercises regularly (定期的) and eats the right kind of food, his eyes will stay in good condition for a long time. All above are natural ways of eye care that help us keep healthy eyes. Being happy all the time can be helpful to a person’s eyesight, too. All in all, eye care is very important, no matter how old a person is. 46．____ is the most important way to protect our eyes. A. Natural eye care B. Taking medicine C. Seeing the doctor D.

Ways of Eye Care B. Ways of Eye Exercises C. Ways of Being Happy D. Ways if Being Healthy 阅读与回答问题(本题共 5 小题，每小题 2 分，满分 l0 分) If the temperature rises by 5 degrees tomorrow, you will probably take off just one coat. But such a change in the average world temperature would be a serious problem. Many animals and plants would not be able to deal with these changes, and would die. The UNEP(联合国环境规划署) released（发布）the Report 2012 on November 21, 2012. It says that if we don’t take action now, the world temperature will have risen by 3 to 5 degrees by the end of this century. A large rise in temperatures could be terrible for us and for many other living things on Earth. Sea levels will rise because higher temperatures will cause melting ice flow into the sea. Large coastal (沿海的) cities in countries such as the Netherlands and Bangladesh could be flooded. Some plants such as corn and sugarcane (甘蔗) will not grow well in higher temperatures. Some countries, such as Brazil and parts of Africa, will not have enough food. The change may cause less rain and even make some places very dry. On November 26, people from around 200 nations and regions gathered again in Doha (多哈) for the annual UN climate talks.“Climate change is coming to all human beings and effective actions need to be taken to deal with it.”president of the conference said at the opening ceremony. 51．What will you probably do if the temperature rises by 5 degrees tomorrow? 52．When was the Report 2012 released by the UNEP? 53．Why will sea level rise? 54．Where did they attend the annual UN climate talks? 55．As a student, what action will you take to deal with the rising temperatures? （请自拟一句话） How dangerous it would be if there was a fire!

Technology is greatly affecting all ways of our lives, from the ways we work to the ways we play. And it even causes a number of social problems such as cloning humans. We have had lots of technology and it has changed our lives a lot. There is no doubt that humans will continue to use more and more technology. Here are some examples of modern technology that will change our ideas and will affect our lives greatly. Global positioning system (GPS) (全球定位系统) It’s a system that uses radio signals from satellites to show exact(精确地) information. It tells you where the user is on the earth in all weather conditions. It’s made up of three parts: satellites, control equipments (设备) on land and receivers. Space Technology Russian and American scientists have worked together for the international Space Station (ISS) for a long time. They hope the ISS will provide a long-lasting lab. Such a lab will bring humans limitless(无限的) advantages. It’s even hoped that one day space technology will take humans to their new houses in space. Underwater Robot Hercules is a kind of underwater robot with some high technology equipments. It will be used to search for ancient ships which were destroyed into the deep sea during their journey long ago. The world is changing so quickly that it’s hard for us to catch up with all the new inventions because they seem to come out every month. It’s important for us to learn about new technology and the role that it plays in our lives. So we should be willing to accept modern technology, or we will fall behind the times. 66．______ can tell you where the user is on the earth exactly. A. Satellites B. Receivers C. Global Positioning System D. Underwater Robot 67．According to the passage, which is NOT true about the ISS? A. It has carried people to other planets. B. It will provide a long-lasting lab for us. C. Russian and American are working for it. D. Humans will get a lot of advantages from it. 68．Hercules is used to ______. A. save lives in the sea B. take picture in the sea C. repair the broken ships D. look for the ancient ships in the sea 69．From the passage, we know that ______. A. the use of GPS is affected by the weather conditions B. it’s very important for us to learn about new technology C. it’s easy for us to catch up with all the new inventions D. technology brings us many advantages such as cloning humans 70．What is the purpose of the passage? A. To help us study some new technology. B. To tell us technology is changing the world. C. To help solve the problems that technology causes. D. To remind us the advantages of technology are limitless. Look at the centre circles of Diagram (图)A and Diagram B. Which of the centre circles looks larger? In fact, they are exactly the same size. Then look at the picture on the right. What do you see? A vase? Or two faces？Does the picture change quickly from one to the other again and again? Maybe or maybe not, but you can never see them at the same time. “What’s happening? Is something wrong with my eyes?” You may wonder at what you see. Don’t worry. Here is how it goes: When we look at things, our eyes send messages to our brains and then our brains interpret（解读）the information. However, sometimes our brains interpret the received information in a wrong way. It seems that our eyes are playing a joke on us. This often happens and we call it “visual illusion(视觉错误)”. Movie makers often make use of visual illusions. They make the objects around actors much smaller or bigger than usual. This makes us believe that the actors are much larger or smaller than they usually are. The movies Jurassic Park and Honey I shrunk the kids just make use of visual illusions. 71．Why does the centre circle in Diagram A look smaller than that in Diagram B? A. something is wrong with our eyes B. the two circles are not the same size C. our brains interpret the information in a wrong way D. the two pictures change quickly from one to the other 72．What do movie makers make use of visual illusions for ? A. To help the actors look better A B B. To make the actors much braver C. To help the actors become stronger D. To make the actors seem different in size 73．In the picture below, it seems that Line AB is shorter than Line CD, but in fact Line AB is as long as Line CD.

We look at things with our eyes. b. Our brains interpret the messages. c. Our brains tell us what we have seen. d. Our eyes send messages to our brains. A. a d b c B. c a b d C. a c d b D. b c a d 75．Where may this passage be from? A. A letter B. An English newspaper C. A science book D. An advertisement In the 13th century, the Italian traveler, Marco polo , traveled a long way to China , During his stay in China , he saw many wonderful things . One of the things he discovered was that the Chinese used paper money . In western countries , people did not use paper money until the 15th century . However , people in China began to use paper money in the 7th century . A Chinese man called CaiLun invented paper almost 2000 years ago. He made it from wood . He took the wood from trees and made it into paper . He then put these pieces of paper together and made them into a book . Now paper still comes from trees . We use a lot of paper every day ! If we keep on wasting so much paper , there will not be any trees on the earth . If there are no trees , there will be no paper . Every day , people throw away about 2800 tons (吨) of paper in our city . It takes 17 trees to make one ton of paper . This means that we are cutting nearly 48000 trees every day . Since it takes more than 10 years for a tree to grow , we must start using less paper now . If we don’t , we will not have enough time to grow more trees to take the place of those we use for paper . So how can we save paper ? We can use both sides of every piece of paper , especially when we are making notes .We can choose drinks in bottles instead of those in paper packets . We can also use cotton handkerchiefs (手帕) and not paper ones . When we go shopping , we can use fewer paper bags . If the shop assistant does give us a paper bag, we can save it and reuse it later . Everyone can help to save paper . If we all think carefully , we can help protect trees . But we should do it now , before it is too late . 76．When he was in China , Marco polo ___________ . A. discovered CaiLun invented paper B. learned to make paper C. saw many wonderful things D. told people about it 77．About _______ tons of paper are thrown away every day in our city.

Have you ever seen a horse with toes(脚趾)？Millions of years ago, horses had many toes. They had four toes on each front foot. They had three toes on each back foot. The horses were no bigger than the cats. These small horses lived in the forest. The toes helped the horses run on the soft, wet ground. At first, it was very hot in the forest. But the weather changed. It became very cold. Many trees could not live in cold weather. The trees died and fell. Open fields took the place of forests. The sun made the ground dry and hard. Horsed began to change, too. They began to get bigger. This took a long time. On the dry, hard land, horses needed only their middle toes for running. Their middle toes became hard.

It is so beautiful. There is a story, saying that whenever you see a rainbow you should run at once to the place where it touches the ground, and there you would find a pot of gold. Of course it is not true. You could not find the pot of gold or its end. No matter how far you run, it always seems far away. A rainbow is not a thing which we can feel with our hands as we can feel a flower. It is only the effect of light shining on raindrops. The raindrops catch the sunlight and break it up into all the wonderful colours which we see. It is called a rainbow perhaps because it is made up of raindrops and looks like a bow（弓). That is why we can never see a rainbow in a clear sky. We see a rainbow only when there is rain in the air and the sun is shining brightly through the clouds. Every rainbow has many colours in the same order. The first or the top colour is always red, and the next comes orange, then yellow, and last of all, blue.
