高考英语科普类阅读答题方法
【实例分析】:Robots are smart. With their computer brains, they help people work in dangerous places or do difficult jobs. Some robots do regular jobs. Bobby, the mail carrier, b

rings mail to a large office building in Washington, D.C. He is one of 250 mail carriers in the United States. Mr. Leachim, who weighs two hundred pounds and is six feet tall, has some advantages as a teacher. One is that he does not forget details. He knows each child’s name, the parents’ names and what each child knows and needs to know. In addition, he knows each child’s pets and hobbies. Mr. Leachim does not make mistakes. Each child goes and tells him his or her name, then dials an identification number. His computer brain puts the child’s voice and number together. He identifies the child with no mistakes. Then he starts the lesson. Another advantage is that Mr. Leachim is flexible. If the children need more time to do their lessons they can move switches. In this way they can repeat Mr. Leachim’s lesson over and over again. When the children do a good job, he tells them something interesting about their hobbies. At the end of the lesson the children switch Mr. Leachim off. 1. The first paragraph of the passage tells us _____. A. human beings are not as smart as robots B. robots will take the place of man to rule the earth C. we can only use robots to do some regular jobs D. robots can help people in many different ways 2.

科普类 [考题1)(NMET 典型例题 In 1901,H.G.Wells, an English writer,wrote a book describing a trip to the moon. When the explorers (探险者) landed on the moon, they discovered that the moon was full of un- derground cities. They expressed their surprise to the "moon people" they met. In turn, the "moon people" expressed their surprise. "Why," they asked, "are you traveling to outer space when you don't even use your inner space?" H.G.Wells could only imagine travel to the moon. In 1969, human beings really did land on the moon. People today know that there are no underground cities on the moon. However, the question that the "moon people" asked is still an interesting one. A growing number of scien- tists are seriously thinking about it. Underground systems are already in place. Many cities have underground car parks. In some cities, such as Tokyo, Seoul and Montreal, there are large underground shopping areas. The "Channel", a tunnel (隧道) connecting England and France, is now complete. But what about underground cities? Japan's Taisei Corporation is designing a network of un- derground systems, called "Alice Cities". The designers imagine using surface space for public parks and using underground space for flats, offices, shopping, and so on. A solar dome (太阳能穹顶) would cover the whole city. Supporters of underground development say that building down rather than building up is a good way to use the earth's space. The surface, they say, can be used for farms, parks, gar- dens, and wilderness. H.G. Wells' "moon people" would agree. Would you? 1. The explorers in H.G.Wells' story were surprised to find that the "moon people" . A. knew so much about the earth B. understood their language C. lived in so many underground cities D. were ahead of them in space technology 2. What does the underlined word "it" (Paragraph 2) refer to? A. Discovering the moon's inner space. B. Using the earth's inner space. C. Meeting the "moon people" again. D. Traveling to outer space. 3. What sort of underground systems are already here with us? A. Offices, shopping areas, power stations. B. Tunnels, car parks, shopping areas. C. Gardens, car parks, power stations. D. Tunnels, gardens, offices. 4. What would be the best title for the text? A. Alice Cities--cities of the future. B. Space travel with H.G.Wells. C. Enjoy living underground. D. Building down, not up.

London (Reuters)—Organic fruit, delivered right to the doorstep. That is what Gabriel Gold prefers, and he is willing to pay for it. If this is not possible, the 26-year-old computer technician will spend the extra money at the supermarket to buy organic food. "Organic produce is always better," Gold said. "The food is free of pesticides (农 药), and you are generally supporting family farms instead of large farms. And more often than not it is lo— cally (本地) grown and seasonal, so it is more tasty." Gold is one of a growing number of shop- pers buying into the organic trend, and supermarkets across Britain are counting on more like him as they grow their organic food business. But how many shoppers really know what they are get- ting, and why are they willing to pay a higher price for organic produce? Market research shows that Gold and others who buy organic food can generally give clear reasons for their preferences— but their knowledge of organic food is far from complete. For example, small amounts of pesticides can be used on organic products. And about three quarters of organic food in Britain is not local but imported (进口) to meet growing demand. "The demand for organic food is increasing by about one third every year, so it is a very fast-growing market," said Sue Flock, a specialist in this line of business. 1. More and more people in Britain are buying organic food because . A. they are getting richer B. they can get the food anywhere C. they consider the food free of pollution D. they like home-grown fruit 2. Which of the following statements is true to the facts about most organic products sold in Britain? A. It grows indoors all year round. B. It is produced outside Britain. C. It is grown on family farms. D. It is produced on large farms. 3. What is the meaning of "the organic trend" as the words are used in the text? A. Growing interest in organic food. B. Better quality of organic food. C. Rising market for organic food. D. Higher prices of organic food. 4. What is the best title for this news story? A. Organic food--healthy, or just for the wealthy? B. The making of organic food in Britain. C. Organic food--to import or not? D. Good qualities of organic food. [考题3](典型例题,C) Laptop (便携式) computers are popular all over the world. People use them on trains and airplanes, in airports and hotels. These laptops connect people to their workplace. In the United States today, laptops also connect students to their classrooms. Westlake College in Virginia will start a laptop computer program that allows students to do schoolwork anywhere they want. Within five years, each of the 1,500 students at the college will receive a laptop. The laptops are part of a $10 million computer program at Westlake, a ll0- year-old college. The students with laptops will also have access to the Internet. In addition, they will be able to use e-mail to "speak" with their teachers, their classmates, and their families. However, the most important part of the
3

laptop program is that students will be able to use computers without going to computer labs. They can work with it at home, in a fast-food restaurant or under the trees—anywhere at all! Because of the many changes in computer technology, laptop use in higher education, such as colleges and universities, is workable. As laptops become more powerful, they become more similar to desktop computers. In addition, the portable computers can connect students to not only the Intemet, but also libraries and other resources. State higher-education officials are studying how laptops can help students. State officials also are testing laptop programs at other universities, too. At Westlake College, more than 60 percent of the staff use computers. The laptops will al- low all teachers to use computers in their lessons. As one Westlake teacher said, "Here we are in the middle of Virginia and we're giving students a window on the world. They can see everything and do everything." 1. The main purpose of the laptop program is to give each student a laptop to . A. use for their school work B. access the internet C. work at home D. connect them to libraries 2. Why is the word "speak" in the second paragraph in quotation marks? A. They don't really talk. B. They use the computer language. C. Laptops have speakers. D. None of the above reasons is correct. 3. Which of the following is true about West Lake College? A. All teachers use computers. B. l, 500 students have laptops. C. It is an old college in America. D. Students there can do everything. 4. A window on the world in the last paragraph means that students can A. attend lectures on information technology B. travel around the world C. get information from around the world D. have free laptops 5. What can we infer (推断) from the passage? A. The program is successful. B. The program is not workable. C. ri'he program is too expensive. D. We don't know the result yet. [考题4](NMET 典型例题,D) You are what you eat. This saying has provided scientists with clues (线索) about the diet of hominids--our early relatives of 3 million years ago. Studying carbon atoms ( 碳 原 子 ) locked up in tooth enamel ( 珐 琅 质 ), two researchers ar- gue against the widely held belief that hominids ate little more than fruits and leaves. Sponheimer and, Julia Lee-Thorp of the University of Cape Town, south Africa, report their findings in Friday's Science. There aren't many clues for us to know the life of early hominids. The shape of hominids' teeth offered the first clues. Large and flat-edged with thick enamel, they looked perfect for eat- ing nuts and fruits, different from the sharp teeth one would want to tear into meat with. The first stone tools, which would help in eating meat, didn't appear until about half a million years later.
4

Scientists have also found marks on hominids' teeth with patterns very similar to those on the teeth of modern day fruit eaters. Sponheimer and Lee-Thorp tried a new method, looking at the chemical composition of the tooth enamel. They studied the enamel for the carbon-13. Animals that eat grasses have higher carbon-13 levels than those eating fruits and other plants. What they found was that the teeth of the hominids had an in-between amount of carbon-13, which meant not only they were eating fruits, they were eating a lot of grass, or animals eating grasses. The lower carbon-13 levels could also come from eating certain types of insects (昆虫). But there are people who understand differently. Prof. Ungar of the University of Arkansas agrees the study offers new suggestions of hominid diet, but disagrees about the suggestion that meat could explain the lower carbon-13 levels. One suggestion might be true though—take good care of your teeth. In 3 million years, a scientist might be using them to figure out what you ate for dinner. 1. Which of the following can be the best title for the text? A. Protect Your Teeth. B. What the Hominid Ate. C. Where the Hominid lived. D. The Formation of Tooth Enamel. 2. Beforthetwo scientists' findings, most people thought that hominids A. lived half a million years ago B. ate mainly fruits and leaves C. used tools to dig grass D. had sharp teeth 3. The two scientists' findings were mainly based on the study about . A. the shape of hominids' teeth B. the teeth marks of early fruit eaters C. the grasses of 3 million years ago D. the makeup of the tooth enamel 4. What is it that Prof. Ungar finds doubtful? A. Hominids possibly ate grass-eating animals. B. Hominids probably had different diets. C. Hominids were basically fruit-and grass-eaters. D. Hominids had lower level of carbon-13 in their teeth. [考题5](典型例题,D) Louis Pasteur, the famous French chemist and bacteriologist, invented "pasteurization". In 1854 Pasteur was made head of the department of Science at the University of Lille and it was there that he made one of his most famous discoveries. Lille was a major center for wine and beer making and some of the local wine-makers asked Pasteur if he could help solve the problem of keeping wine fresh. At that time, it was believed that food drinks go "bad" due to a purely chemical process (变化过程). But during a series of experiments Pasteur proved that tiny living organisms (微生物) caused food and drinks to go bad.In the case of wine and beer the organ- isms are already present in the form of the various yeasts (酵母) that caused the fermentation (发酵) process. Pasteur discovered that heating the wine gently for a few minutes after it had fer- mented would kill off the yeast that was left in the wine, with the result that the wine would re5

main fresh for much longer. He also proved that food and drinks could be turned bad by other or- ganisms that were present in the air, and that they too would keep fresh much longer if they were kept in airtight containers. The heating process was so successful that it made Pasteur famous. It was named "pasteurization'' in his honour, and by about 1900 it had been widely used for processing and bottling cows' milk. The result was a huge drop in the number of bottle-fed babies dying from infant diar- rhea (婴儿腹泻) and from that time on it had been a standard treatment for milk and many other food products. This simple process has saved thousands, possibly millions, of lives world wide. 1. Pasteur became in 1854. A. the chairperson of the Science Department at the University of Lille B. the director of a chemical laboratory at the University of Lille C. the general manager of a large beer-making company D. the president of the University of Lille 2. According to the passage, Lille was a major center for he mid-19th century. A. growing grain crops B. making beer and wine C. doing chemical research D. producing various kinds of yeast 3. In the last sentence of Paragraph 1, the underlined word "they" refers to . A. wine and beer B. food and drinks C. the various yeasts D. other organisms 4. We can infer from the passage that Pasteur's discovery . A. is no longer widely used for treating milk and other food products B. did not bring much profit to the wine makers in Lille C. has done a lot of good to childcare in the world D. had greatly reduced the number of wars in the world [考题 6] (典型例题, D) After a busy day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the day. The rest that you get while sleeping makes it possible for your body to prepare itself for the next day. There are four levels of sleep, each being a little deeper than the one before. As you sleep, your body relaxes (放松) little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts (变换) back and forth from one level of sleep to the other. Though your mind slows down, you will dream from time to time. Scientists who study sleep point out that when dreaming occurs, your eyeballs begin to move more quickly (although your eyelids are closed). This stage of sleep is called REM, which stands for rapid eye movement. If you have trouble falling asleep, some people recommend (建议) breathing very slowly and very deeply. Other people believe that drinking warm milk will make you drowsy. There is also an old suggestion that counting sheep will put you to sleep. 1. The text suggests that not getting enough sleep might make you .
6

A. suffer from Ix)or health B. feel tired and nervous C. dream more often D. breathe quickly 2. During REM, . A. you move restlessly B. you start dreaming C. your mind stops working D. your eyeballs move quickly 3. The underlined word "drowsy" in the last paragraph probably means . A. lazy B. sleepy C. relaxed D. pleased 4. A good title for this text might be . A. Dreams B. Sleep C. Good Health D. Work and Rest [考题7](典型例题,A) Dolphins (海豚) are not fish, but warm-blooded animals. They live in groups, and speak to each other in their own language. In this they are like other animals, such as bees and birds. But dolphins are very different from almost all land animals. Their brain is nearly the same size as our own, and they live a long time.., at least twenty or thirty years. Like some animals, dolphins use sound to help them find their way around. They also make these sounds to talk to each other and to help them find food. We now know they do not use their ears to receive these sounds, but the lower part of the mouth, called the jaw. Strangely, dolphins seem to like man, and for thousands of years there have been stories about the dolphin and its friendship with people. There is a story about sailors in the 19th century. In a dangerous part of the sea off the coast of New Zealand, they learnt to look for a dolphin called Jack. From 1871 to 1903 Jack met every boat in the area and showed in the way. Then in 1903 a passenger on a boat called The Penguin shot and wounded Jack. He recovered and for nine years more continued to guide all ships through the area—except for The Penguin. Today, some people continue to kill dolphins, but many countries of the world now protect them and in these places it is against the law to kill them. 1. Dolphins are different from many other animals in that they . A. live in groups B. have large brains C. are warm-blooded D. have their own language 2. Which of the following does the dolphin use to help it find its way around? A. Its nose. B. Its ears. C. Its mouth. D. Its eyes. 3. Why did the sailors off the coast of New Zealand look for Jack? A. He was lonely and liked to be with people. B. They enjoyed playing with him. C. He was seriously wounded. D. They wanted his help. 4. By telling the story of Jack the writer wanted to show that . A. dolphins are friendly and clever B. people are cruel to animals C. Jack is different from other dolphins D. dolphins should be protected by law [考题8](典型例题, B) If you dream of going .some place warm to escape the cold winter weather, a trip to a recent- ly discovered planet would certainly warm you right up. The planet, named OGLE-TR-56b, has temperatures of more than 3,000 . F. "This is the
7

hottest planet we know about." says Dr. Dimitar Sasselov, a scientist who led the discovery team."It is hot enough to have an iron fog and to rain hot iron droplets (细沫)." The new planet is 30 times farther away than any planet discovered by scientists before. It is in the Milky Way (银河) but it is not in our solar (太阳的) system. The new planet moves around a star much like our sun, however. Scientists discovered the planet by using a new plan- et-searching method, called "transit technique". They were able to catch sight of the planet when it moved in front of its star. causing the star's light to dim (变暗). Scientists compare the method to discovering the shadow of a bee flying in front of a searchlight 200 miles away. "We believe the door had been opened wide to go and discover planets like Earth." says Sasselov. 1. We can infer from the passage that . A. there is iron on the view planet B. we could go to the new planet in winter C. the star could block our view of the new planet D. scientists are studying the weather on the new planet 2. The "transit technique" can . A. help dim the tight of a star B. help scientists with a searchlight C. help discover a bee on a planet D. help find a planet moving before its star 3. Which is the best title for the passage? A. New Planet-searching Technique. B. New Distant Discovery. C. Space Searching. D. Dream Planet. [考题9](NMET 典型例题 At one time, computers were expected largely to remove the need for paper copies of docu- ments (文件) because they could be stored electronically. But for all the texts that are written, stored and sent electronically, a lot of them are still ending up on paper. It is difficult to measure the quantity of paper used as a result of Intemet-connected comput- ers, although just about anyone who works in an office can tell you that when e-mail is intro- duced, the printers start working overtime. "I feel in my bones this revolution is causing more trees to be cut down,' .says Ted Smith of the Earth Village Organization. Perhaps the best sign of how computer and Internet use pushes up demand for paper comes from the high-tech industry itself, which sees printing as one of its most promising new markets. Several Internet companies have been set up to help small businesses print quality documents from a computer. Earlier this week Hewlett-Packard Co. announced a plan to develop new technolo- gies that will enable people to print even more so they can get a hard copy of a business document, a medical record or just a one-line e-mail, even if they are nowhere near a computer. As the com- pany sees it, the more use of the Internet the greater demand for printers. Does all this mean environmental concerns (环境问题) have been forgotten'?. Some activists suggest people have been led to believe that a lot of dangers to the environment have gone away. "I guess people believe that the problem is taken care of,
8

because of recycling (回收利用)" said Kelly Quirke, director of the Rainforest Action Network in San Francisco. Yet Quirke is hopeful that high-tech may also prove helpful. He says printers that print on both sides are growing in popularity. The action group has also found acceptable paper made from materials other than wood, such as agricultural waste. 1. The growing demand for paper in recent years is largely due to . A. the rapid development of small businesses B. the opening up of new markets C. the printing of high quality copies D. the increased use of the Intemet 2. Environmentalists believe one possible way of dealing with the paper situation is . A. to encourage printing more documents B. to develop new printers using recycled paper C. to find new materials for making paper D. to plant more fast-growing trees 3.Hewlett-Packard Co. has decided to develop new technologies because . A. people are concerned about the environment B. printers in many offices are working overtime C. small companies need more hard copies D. they see a growing market for printers 4.What would be the best title for the text? A. Computers and Printers. B. E-mail and the Business World. C. Intemet Revolution and Environment. D. Modem Technology and New Markets. [考题10](典型例题,A) A newspaper in Helsinki, Finland, recently published a cartoon of a baby with a mobile phone, telling his parents that his diaper (尿布) needed changing. But it's hardly a joke. Helsinki is home to Nokia, the mobile-phone maker. It's one of the most "mobile" cities in the world: About 92 percent of its households have at least one mobile phone. And the kids start young. "A relatively normal age to get a mobile phone is now 7," says Jan Virkki, marketing man- ager for a mobile-phone company. Among the second graders at the Kulosaari Elementary School, the most popular object desire this year is not a Barbie or a Garneboy.It is a Nokia mo- bile phone with a picture of their own choice on the screen. "One of the first things we discuss when school starts is the rules for mobile phones," says Tila Korppi, a teacher. Among the rules, you have to put it away out of sight. You cannot turn it on. You cannot send text massagers to your friends, or play amusing tunes (令人发笑的曲调) in class, or call your parents or call for a pizza during history. 1. The author uses the newspaper cartoon to show that . A. he is good at telling jokes B. he cares much for children C. mobile phones are toys for new-born babies D. mobile phones are widely used in Finland
9

2. The passage is mainly about . A. different uses of mobile phones B. a successful mobile-phone maker C. effects of mobile phones on children D. school rules for the use of mobile phones [考题11](NMET 典型例题 There is one foreign product the Japanese are buying faster than others, and its popularity has caused an uneasy feeling among many Japanese. That product is foreign words. Gairaigo-words that come from outside-have been part of the Japanese language for cen- turies. Mostly borrowed from English and Chinese, these terms are often changed into forms no longer understood by native speakers. But in the last few years the trickle (涓涓细流) of foreign words has become a flood, and people fear the increasing use of foreign words is making it hard for the Japanese to understand each other and could lead to many people forgetting the goocl qualities of traditional (传统的) Japanese. "The popularity of foreign words is part of the Japanese interest in anything new," says uni- versity lecturer and writer Takashi Saito. "By using a foreign word you can make a subject seem new, which makes it easier for the media (媒体) to pick up." "Experts (专家) often study abroad and use English terms when they speak with people in their own fields. Those terms are then included in government white papers." Sam Muturo Kal, president of the National Language Research Institute. "Foreign words find their way easily into announcements made to the general public, when they should really be explained in Japanese." Against the flow of new words, many Japanese are turning back to the study of their own language. Saito's Japanese to Be Read Aloud is one of many language books that are now flying off booksellers' shelves. "We were expecting to sell the books to young people," said the writer, "but it tums out they are more popular with the older generation, who seem uneasy about the future of Japanese." 1. What advantages do foreign words have over traditional Japanese terms? A. The ideas expressed in foreign words sound new. B. Foreign words are best suited for announcements. C. Foreign words make new subjects easier to understand. D. The use of foreign words makes the media more popular. 2. In the opinion of Takshi Saito, Japanese people . A. are good at learning foreign languages B. are willing to learn about new things C. trust! the media D. respect experts 3. Which of the following plays an important part in the spread of foreign words? A. The media and government papers. B. Best-selling Japanese textbooks. C. The interest of young Japanese.
10

D. Foreign products and experts. 4. The book Japanese to Be Read Aloud . A. sells very well in Japan B. is supported by the government C. is questioned by the old generation D causes misunderstanding among the readers [考题12](NMET 典型例题) Deserts are found where there is little rainfall or where rain for a whole year falls in only a few weeks' time. Ten inches of rain may be enough for many plants to survive (存 活) if the rain is spread throughout the year, If it falls, within one or two months and the rest of the year is dry, those plants may die and a desert may form. Sand begins as tiny pieces of rock that get smaller and smaller as wind and weather wear them down. Sand dunes (沙丘) are formed as winds move the .sand across the desert. Bit by bit, the dunes grow over the years, always moving with the winds and changing the shape. Most of them are only a few feet tall, but they can grow to be several hundred feet high. There is, however, much more to a desert than sand. In the deserts of the southwestern United States, cliffs (悬崖) and deep valleys were formed from thick mud that once lay beneath a sea more than millions of years ago. Over the centuries, the water dried up. Wind, sand, rain, heat and cold all wore away at the remaining rocks. The faces of the desert mountains are always changing —very, very slowly —as these forces of nature continue to work on the rock. Most deserts have a surprising variety of life. There are plants, animals and insects that have adapted to life in the desert. During the heat of the day, a visitor may see very few signs of living things, but as the air begins to cool in the evening, the desert comes to life. As the sun begins to rise again in the sky, the desert once again becomes quiet and lonely. 1. Many plants may survive in deserts when . A. the rain is spread out in a year B. the rain falls only in a few weeks C. there is little rain in a year D. it is dry all the year round 2. Sand dunes are formed when . A. sand piles up gradually B. there is plenty of rain in a year C. the sea has dried up over the years D.pieces of rock get smaller 3. The underlined sentence in the third paragraph probably means that in a desert there is . A. tm much sand B. more sand than before C. nothing except sand D. something else besides sand 4.It can be learned from the text that in a desert A. there is no rainfall throughout the year B. life exists in rough conditions C. all sand dunes are a few feet high
D. rocks are worn away only by wind and heat
