第3题

America's genius with high technology may have put men on the moon, but there is growing s

kepticism (怀疑) about its ability to solve human problems closer to home.

In fact, a subtle but significant shift from purely technological solutions is already under way as scientists argue openly for new directions in research.

A growing number of scientists insist that answers to the world's problems will not come from a flashier array of electronics and machines. Instead, as they see it, solutions must evolve from a better understanding of the humans that drive the system and from a fuller appreciation of the limits and potential of the earth's resources.

What this means is an increased emphasis on the life and earth sciences, on sociology, psychology, economics and even philosophy.

More and more of the best minds in science, particularly young researchers, are being drawn into these developing fields.

All this is not to say that technological creativity will not play a critical role in solving energy and food shortages, or that answers to environmental difficulties will not come from further advances in the same technologies that may have helped cause the problems.

Where the real challenge lies, in the view of the new breeds of scientists, is finding ways to produce goods to meet the world's needs, using less of the raw materials that are becoming scarce.

Which of the following best expresses the main idea？

A．A growing number of Americans are doubtful about what high technology can do in solving the world's problems.

B．Many scientists are starting to believe that the better understanding of human beings will play a more decisive role in solving the world's problems.

C．More and more young scientists are trying their best to find new ways to solve the world's problems.

D．Technological creativity will still play a very important part in solving the world's problems.

听力原文： Surtsey was born in 1963. It was a great event for scientists. They were lucky enough to see the birth of this volcanic island. It began at 7: 30 a.m. on 14th November. A fishing boat was sailing near Iceland. The boat moved under the captain's feet. He noticed a strange smell. He saw some black smoke. A volcano was erupting. The bottom of the grey Atlantic was open. Red-hot rocks, flames and smoke were rushing up from a split in the sea-bed. The island grew quickly. It was 10 meters high the next day and 60 meters high on 18th November. Scientists flew to Reykiavik to watch. It was very exciting. Smoke and flames were still rushing up. Pieces of red-hot rock were flying into the air and falling into the sea. The sea was boiling and there was a strange light in the sky. Surtsey grew and grew. Then it stopped in June 1967. It was 175 meters high and 2 kilometers long. And life was already coming to Surtsey. Seeds came over the sea. Plants grew. Birds came. Some scientists built a house to learn about the young island. A new island is like a new world.

(33)

A．The smoke and flames of the volcano.

B．The red hot rock that came from the volcano.

C．The middle of the earth in the sea.

D．An island near Reykiavik in Iceland.

第6题

How much living space does a person need？ What happens when his space needs are not met？ S

cientists are making experiments on rats to try to determine the efforts of over crowded conditions on man. Recent studies have shown that the behaviour of rats is greatly affected by space. If rats have enough living space, they eat well, sleep well and produce their young well. But if their living conditions become too crowded, their behaviour and even their health change obviously. They can't sleep and eat well, and signs of fear and worry become clear. The more crowded they are, the more they tend to bite each other and even kill each other. Thus, for rats, population and violence are directly related. Is this a natural law for human society as well？ Is enough space not only satisfactory, but necessary for human survival？

The writer is mainly talking about ______.

A．a person's living space needs

B．building and floors

C．equipment and conditions

D．population and violence

第7题

A hearing test that analyses brain waves for subconscious responses to sound has recently

been devised by a team of specialists at the University of Iowa. Instead of depending on the patient to indicate when he hears a laboratory-controlled noise, as in the traditional form. of testing, this new method, called electric response audiometry, enables audiologists to trace the noise's path directly from the ear to the brain while the patient relaxes or sleeps. Although brain responses have been used in other auditory tests for some time, the University of Iowa specialists are the only scientists to date who analyze simultaneously three components of hearing—the responses of the middle ear, the auditory nerve, and the brain stem. This information helps to identify the precise location of a hearing problem and, at the same time, to measure its severity. While electric response audiometry is not meant to replace conventional means of testing, it is specially effective in diagnosing hearing problems in very young children, multiply handicapped individuals, and psychologically disturbed persons because it does not require the patient's active participation.

According to the passage, electric response audiometry can be used ______.

A．whether a person is awake or asleep

B．only if a person is relaxed

C．particularly if a person hears a loud noise

D．particularly when a person is dreaming

What Kinds of Food Do People Need?Scientists have learned a great deal about the kinds o

What Kinds of Food Do People Need？

Scientists have learned a great deal about the kinds of food people need. They say that there are several kinds of food people should eat every day. What are these classes of food？ They are 1) green vegetables of all kinds, such as string beans, peas, lettuces, and cabbages; 2) fruits such as apples, peaches and bananas; 3) other vegetables, examples of these are beets, onions, carrots, tomatoes and so on; 4) meat of all kinds, fish and eggs; 5) milk and food made from milk, such as butter, cheese and ice cream; 6) bread or cereal. Rice is also in this class of food.

People in different countries and different areas of the world eat different kinds of things. Scientists say that none of these differences are really important. It doesn't matter whether food is eaten raw or cooked, canned or frozen. It doesn't matter if a person eats dinner at 4 o'clock in the afternoon or at 11 o'clock at night. The important thing, they say, is that every day a person should eat something from each of these kinds of food.

There are two problems, then, in feeding the ever-increasing number of people on earth. The first is to find some way to feed the world population so that no one is hungry. The second is to make sure that people everywhere have the right kinds of food to make them grow to be strong and healthy.

61、What have scientists learned a great deal about？()

A.The kinds of food that should be eaten every day

B.whether to eat food raw or cooked

C.When to eat food every day

A.Eat one's meals at regular intervals

B.eat raw or cooked food, but not canned or frozen food

C.Eat a variety of necessary foods

D.eat vegetables and fruits more than meat and cereal

63、What problems are facing the world today？()

第10题

Lawrence Bragg, the Cavendish Professor of Experimental Physics, once wrote: "I will try t

o define what I believe to be lacking in our present courses for undergraduates. They do not learn to write clearly and briefly, marshalling their Points in due and aesthetically satisfying order, and eliminating inessentials. They are inept at those turns of phrase or happy analogy which throw a flying bridge across a chasm of misunderstanding and make contact between mind and mind. They do not know how to talk to people who have a very different training from them, and how to carry conviction when plans for action of vital importance to them are made." Perhaps this would not matter too much if physical science students were destined only for the backrooms of scientific laboratories. But recent trends indicate that many science graduates end up in careers far from their initial training. Many a physics graduate is to be found predicting the future market in the Square Mile; many a chemist is hyping it up in public relations. One of the main complaints of those graduates who leave science is that their course concentrated on producing students equipped to follow a research career, and that the underlying assumption was that such research would be carried out in an academic environment. Those who eventually find themselves elsewhere, whether as scientific researchers or in another capacity, often feel ill equipped for the environment of commerce and industry. These young people often have to write off their last three years' training. At most, all they got from their BSc was a grounding in scientific logic and numeracy. The factual content of their subject was just so much excess baggage.

The academic scientific community which supplied the excess baggage can be heard loudly bemoaning the "loss" of talented young scientists. Yet academic scientists also complain about scientific illiteracy in exactly those non-science professions, which are now welcoming science students.

Perhaps if there were less moaning and greater acceptance of this intellectual osmosis(渗透), the exodus could be turned to everyone's advantage. The refugee graduates ought to be able to think of their scientific knowledge and training as a bonus. It ought to make a positive, constructive contribution to their working lives, and be a source of insight for their colleagues. At the same time, the scientific community should be reaping the benefit of this broad and influential distribution of people who are sympathetic to science.

The reason why this is not the case is that science graduates are often unable to share their science with their nonscientific colleagues. They are unable to communicate. Instead of building Bragg's "flying bridge" they find themselves erecting barriers whenever called upon to explain scientific concepts in everyday terms. Attitudes in the scientific community are changing. In 1985, the Royal Society published a report on the public understanding of science in Britain. Its conclusions took many members of the scientific community by surprise.

The report advocated increased cooperation with the media, more training in communication skills for scientists and wider science education. It also recommended that communication skills be an integral part of every undergraduate science course. The response in British universities has been patchy, to say the least, the reasons are not clear. It may be that nothing more than straightforward inertia is responsible. Being more charitable, academic scientists may simply feel their job is to teach science and that any attempts to delve into the art of communication will be ill received by both students and the outside world. However, there is evidence to suggest these fears are ill founded. For example, the departments of chemical and electrical engineering at Imperial College, London, have for many years offered their students tuition in giving talks. The
