A few years back, the decision to move the Barnes, a respected American art institution, f

r the construction of what we call modern civilization. Every dispensable item of contemporary technology, from canal locks to dial telephones to penicillin, was pieced together from the analysis of data provided by one or another series of scientific experiments. Three hundred years seems a long time for testing a new approach to human interaction, long enough to settle back for critical appraisal of the scientific method, maybe even long enough to vote on whether to go on with it or not. There is an argument.

Voices have been raised in protest since the beginning, rising in pitch and violence in the nineteenth century during the early stages of the industrial revolution, summoning urgent crowds into the streets any day on the issue of nuclear energy. The principal discoveries in this century, all in all, are the glimpses of the depth of our ignorance about nature. Things that used to seem clear and rational, matters of absolute certainty—Newtonian mechanics, for example—have slipped through our fingers, and we are left with a new set of gigantic puzzles, cosmic uncertainties, ambiguities; some of the laws of physics are amended every few years, some are canceled outright, some undergo revised versions of legislative intent as if they were acts of Congress.

Just thirty years ago we call it a biological revolution when the fantastic geometry of the DNA molecule was exposed to public view and the linear language of genetics was decoded. For a while, things seemed simple and clear, the cell was a neat little machine, a mechanical device ready for taking to pieces and reassembling, like a tiny watch. But just in the last few years it has become almost unbelievably complex, filled with strange parts whose functions are beyond today's imagining.

It is not just that there is more to do; there is everything to do. What lies ahead, or what can lie ahead if the efforts in basic research are continued, is much more than the conquest of human disease or the improvement of agricultural technology or the cultivation of nutrients in the sea. As we learn more about fundamental processes of living things in general we will learn more about ourselves.

What CAN'T be inferred from the 1st paragraph？

A．Scientific experiments in the past three hundred years have produced many valuable items.

B．For three hundred years there have been people holding hostile attitude toward science.

C．For centuries scientific discoveries have been hailed by the human world unanimously.

D．Three hundred years is not long enough to settle back for critical appraisal of the scientific method.

听力原文： In the past two years, millions of Americans have suddenly embraced the bicycle as if it were a startling new invention. Annual bike sales doubled between 1960 and 1970, and there are nearly 70 million bikes in the United States today. That's more than two for every three automobiles.

Of course, the bike has been around for more than 150 years, and this isn't America's first bicycle boom. A wave of bike enthusiasm swept the land in the late 1800s and bicycle production hit two million units in 1897. Then with the coming of the auto, bicycling declined, and for decades remained popular only with children and a few adult faddists.

Now, national preoccupation with air pollution and physical fitness has brought the bike back to the forefront—particularly with adults. More than eight million bikes were sold in the United States last year and a third of them went to adults. The year before, only 15 percent of new bike sales were for adults.

(30)

A．The use of bikes is a new invention in the U.S.

B．Annual bike sales doubled in the 60s in the U.S.

C．The producers made 70 million bikes every year.

D．The number of bikes is two times that of cars in the U.S.

other men have achieved. An American university president once commented that Einstein had created a new outlook, a new view of the universe. It may be some time before the average mind understands fully the identity of time and space and so on-but even ordinary men understand now that the universe is something larger than ever thought before. By 1914 the young Einstein had gained world fame. He accepted the offer to become a professor at the Prussian Academy of Science in Berlin. He had few duties, little teaching and unlimited opportunities for study, but soon his peace and quiet were broken by the First World War.Einstein hated violence. The misery of war affected him deeply, and he sat unhappily in his office doing little. He lost interest in his research. Only when peace came in 1918 was he able to get back to work. In the years following World War I honors were increasingly heaped on him. He became the head of the Kaiser Whihem Institute of Theoretical Physics. In 1921 he won the Noble Prize, and he was honored in Germany until the rise of Nazism when he was driven from Germany because he was a Jew.(1)、The main idea of Paragraph 1 is the change in human thought produced by Einstein.()

Passage Two

How can a single postage stamp be worth $ 16,800？

Any mistake made in the printing of a stamp raises its value to stamp collectors. A mistake on one in expensive' postage stamp has made the stamp worth a million and a half times its original value.

The mistake was made more than a hundred years ago in the British colony of Mauritius, a small is land in the Indian Ocean. In 1847 an order for stamps was sent to a London printer, and Mauritius was to become the fourth country in the world to issue stamps.

Before the order was filled and delivered, a ball (舞会) was planned at Mauritius' Government House, and stamps were needed to send out the invitations. A local printer was instructed to copy the de sign for the stamps. He accidentally inscribed the words "Post Office" instead of "Post Paid" on the sever al hundred stamps that he printed.

Today there are only twenty-six of these misprinted stamps left--fourteen "One Penny Orange-Reds" and twelve "Two Penny Blues". Because of the Two Penny Blue's rareness (罕见) and age, collectors have paid as much as $ 16,800 for it.

A. there are few others like it

B. there are no errors on the stamps

C. a mistake is made in the ,printing

D. both A and C

A.The offensive back

sion that Jerry was the most important and had the greatest effect upon my life. His family moved to my block when I was only 10. Jerry was 15 at the time, but the fact that he was so much older than me seemed to make no difference to him. I was very glad that he liked me. We took long walks together, on which he would tell me stories he had heard form. TV and radio programs.

But as months went by, a change came into our friendship. Jerry almost stopped coming by the house, and every time I went to his house or telephoned, he put me off with some excuses such as "I'm studying now" or "I've got some jobs to do for Mum". When we passed on the street, he would still give me a warm smile and friendly wave with a "Hi, kid", but he would hardly ever stop to talk. Finally I realized that he was no longer interested in me and that his，taste had changed. I noticed him with a girl once in a while and several times saw him going out in his family's car on a Friday or Saturday night. I simply couldn't understand what was so great about girls and parties.

But I was hurt when he finally made me know that our friendship was at an end. Of course he didn't really mean to hurt me, but it was a long time before I realized that it was an age problem that caused the break. There were a world of differences between the ideas and interests of a 17-year-old and a 12-year-old. Now that I'm over sixteen myself, I realized this, and the hurt I got then has become happy memories of the good times we were once together. I wonder if millions of other boys and girls have had a similar experience.
