听力原文： Many scientists had very bad proficiency records in their school days. Famous inventor Thomas Edison, for instance, did so poorly in his first years of school that his teacher warned his parents that he'd never be a success at anything. Similarly, Henry Ford, the father of the auto-industry, had trouble in school with both reading and writing. But perhaps the best example is Albert Einstein, whose parents and teachers suspected that he was retarded because he responded to questions so slowly and in a stuttering voice. Einstein's high school record was poor in everything but math, and he failed his college entrance exams the first time. Even out of school the man had trouble holding a job-until he announced the theory of relativity.

What did Thomas Edison, Henry Ford and Albert Einstein have in common when they were studying at schools？

A．They were top students.

B．They went to best public schools.

C．They were not very good students.

D．Their teachers thought they would be very successful.

听力原文： It was not until one hundred and fifty years ago that scientists learned about the existence of dinosaurs. Thanks to an English doctor and his wife, the door was opened to this zoological study. Reasoning that these animals' tremendous size must have made them terrible creatures, scientists combined two Greek words, deimos, meaning terrible, and sauros, meaning lizards, to form. the word dinosaur.

After many years of study, they determined that these beasts roamed the earth for millions of years, and ceased to exist some sixty million years ago.

Unbelievable as it may seem, not all dinosaurs were carnivorous, that is, meat eating. Many were herbivorous, or vegetarians.

By reassembling the bones found at digging sites, scientists have been able to reconstruct the skeletons and learn great deal about the dinosaur's living conditions. They have learned that dinosaurs inhabited not only the land, but also the water and sky.

(33)

A．Beasts.

B．Herbivorous.

C．Carnivorous.

D．Dinosaurs.

听力原文：Scientists have observed that plants themselves produce many poisonous chemicals

听力原文： Scientists have observed that plants themselves produce many poisonous chemicals for defence against insects. But insects have developed ways of dealing with them and, in fact, have been eating plants for about 250 million years. Now insects are using these same mechanisms to deal with man-made poisons--insecticides. This is why resistance of insects to insecticides has developed so rapidly.

What should be done？ Scientists studying the problem suggest that farmers use less insecticides. At the moment, farmers regularly spray crops as a precaution against problems that are caused by large numbers of pests. They should, instead, spray only where pests have actually been seen. Secondly, farmers could use a combination of two or three insecticides at once. To survive, the insects would need to become resistant to two or more poisons at the same time.

The most surprising suggestion, perhaps, is that, at certain times of the year, farmers should actually try to attract new insects onto the crops they are trying to protect. The new insects will mate with those which survived from a certain kind of insecticide and will lessen the latter's resistance to it.

Scientists hope that these and other measures will postpone the day when farmers and scientists will have to stand by while new super-bugs which may be resistant to all our poisons invade our farms and eat our crops.

(33)

A．Plants can produce some poisonous chemical for defence against insects.

B．Insects have been eating plants for many million years.

C．Insects have developed ways of dealing with poisonous chemicals produced by plants themselves.

D．Insects have already developed some resistance to man-made poisons.

听力原文：Scientists in many developing nations are studying a way to protect and control t

听力原文： Scientists in many developing nations are studying a way to protect and control the use of forests, fishing water, grasslands and other resources. They call the system "common property". It means that people join together to abate and protect the resources. Scientists say that increased population is damaging the world resources. Too many trees are cut; grasslands and croplands are destroyed. Too many fish are taken from the fishing area. There are two traditional ways to deal with this situation. One is public: the government agency decides who may use the resources and when; or the property can be private: the owner decides how to protect the resources. Experts say these two methods often are not effective, however. They believe there is a third possibility that is neither completely governmental nor completely private. It is communal or joint control of the resources.

Scientists know that this idea of common property is not new. The system has been believed successful for a long time by groups in many countries. In South Asia, some villagers have governing systems to protect everyone's right to irrigation water. In part of Central Africa, there are traditional rules that banned the killing of some wild animals. Farmers in Syria have a system to share grasslands and fisherman in Turkey have a system to make sure no one takes too many fish. Scientists say such systems usually were developed by small groups to deal with limited problems. Rules are simple and the enforcement is based on traditional value and ways of doing things. Scientists believe such systems also would be effective in other situations. They are studying how it might produce more cooking rules for people in Indian villages. The scientific group in Costa Rice is studying common property to control land area. And a government group in Zimbabwe is studying the system to protect wild animals. Scientists do not say the common property system will solve all resource needs in developing nations, buy they believe it provides one important way to deal with the problem.

(33)

A．Property owned by a group of people.

B．Privately-owned property.

C．Government-owned property.

D．People's joint effort to share and protect natural resources.

听力原文：American scientist Lawrence Witmer of Ohio University in Athens, Ohio has found t

听力原文： American scientist Lawrence Witmer of Ohio University in Athens, Ohio has found that many images of dinosaurs may be wrong. For years, pictures of the ancient creatures have shown their nose openings near the top of the head. The new study suggests the dinosaurs' nostrils were just above the mouth.

Dinosaurs used their nostrils to breathe, smell and control their body temperature. The new theory could help explain how the huge creatures were able to survive by using their sense of smell to find food, a mate and possible enemies.

Many of the early dinosaur remains recovered by scientists were from huge creatures called sauropods. Scientists believed that sauropods must have lived in water because their bodies were so huge and their necks were so long.

Nostrils high on the head would have permitted the dinosaurs to breathe while partly under water. The discovery of a sauropod head bone in 1884 added support for this belief. The skull had a large hole at the top of the head.

Professor Witmer found that the hole scientists once thought was a nostril in dinosaurs is just one part of the larger nasal passage. He found that the nostrils were farther forward and closer to the mouth. He says this new nostril position was hue for all dinosaurs.

A．Biology textbook.

B．Scientific essay.

C．Science fiction.

D．Science report.

听力原文：As is known to all, scientists and philosophers had studied the human body and it

听力原文： As is known to all, scientists and philosophers had studied the human body and its functions from very early times. Unfortunately, many of the ideas and theories, correct and incorrect, were accepted without question for a great number of years. But by the 16th century, knowledge gained through chemical experiments was beginning to make some people think more deeply about how the human body works.

A most important medical discovery was made by William Harvey in 1628. He found out that the blood is circulated round the body in one direction only by the pumping action of the heart. It had previously been incorrectly thought that the blood moved with a backward and forward motion.

Early in the 17th century a new instrument came into use that was to open up a whole new area in the study of medical and scientific matters. This was the microscope.

The first instruments were not very efficient. They were able to magnify only a very small part of the object and this was always surrounded by rings of coloured light. Nevertheless a great step forward had been taken which was of vital importance for future research and development.

(30)

A．Scientists and philosophers bad never studied the human body and its functions.

B．Many of the ideas and theories that people used to accept were all incorrect.

C．People used to accept ideas and theories.

D．People used to accept undoubtedly many of the ideas and' theories, correct and incorrect.

听力原文： Experts on dyslexia say that the problem is not a disease. They say that persons with dyslexia use information in a different way. One of the world's greatest thinkers and scientists named Albert Einstein was dyslexic. Dr Einstein said that he never thought in words the way that most of us do. He said that he thought in pictures instead. Other famous people who suffered from dyslexia include Leonardo Da Vinci, a celebrated Roman artist, Thomas Edison, a well-Known American inventor and a former American Vice president, Nelson Rockfeller.

Dyslexia was first recognized in Europe and then in the United States over 80 years ago. Many years passed before doctors discovered that people with this disorder were not mentally slow or disabled. The doctors found that the brains of dyslexia persons are rather different. In brains of most people, the left side, the part that controls language, is larger than the fight side. In the people with dyslexia, the right side of the brain is much bigger. However, research has shown that dyslexia is more common in men than in women, and it is also found more often in people who are left-handed.

(30)

A．The left-handed women.

B．The left-handed men.

C．Excellent female scientists or artists.

D．Some celebrated female presidents.

听力原文： Man has a big brain. He can think and speak. Scientists used to think that men are different from animals because they can think and learn. They now know that animals can learn —dogs, rats, birds —and worms —can learn. So scientists are beginning to understand that men are different from animals because they can speak. Animals cannot speak. They make noises when they are afraid, or angry, or unhappy. Apes are our nearest cousins. They can understand some things more quickly than human beings, and one or two have learned a few words. But they are still different from us. They cannot join words and make sentences. They cannot think like us because they have no language. They can never think about the past or the future.Language is a wonderful thing. Man has been able to develop civilization because he has language. Every child can speak his own language very well when he is four or five —but no animal learns to speak. How do children learn？ Scientists do not really know. What happens when we speak？ Scientists do not know. They only know that man can speak because he has a big brain.

(34)

A．Because he has a big brain.

B．Because he learns to speak.

C．Because he develops civilization.

D．Because he knows many words.
