Passage Two:Questions 26 to 30 are based on the following passage.A breakthrough (突破) in the provision of energy from the sun for the European Economic Community (EEC) could be brought forward by up to two decades, if a modest increase could be provided in the EEC’s research effort in this field, according to the senior EEC scientists engaged in experiments in solar energy at EEC’s scientific laboratories at Ispra, near Milan.

The senior West German scientist in charge of the Community’s solar energy programme, Mr. Joachim Gretz, told journalists that at present levels of research spending it was most unlikely that solar energy would provide as much as three per cent of the Community’s energy requirements even after the year 2000. But he said that with a modest increase in the present＜ sums, devoted by the EEC to this work it was possible that the breakthrough could be achieved by the end of the next decade.

Mr. Gretz calculates that if solar energy only provided three per cent of the EEC’s needs, this could still produce a saving of about a billion pounds in the present bill for imported energy each year. And he believes that with the possibility of utilizing more advanced technology in this field it might be possible to satisfy a much bigger share of the Community’s future energy needs.

At present the EEC spends about $2.6 millions a year on solar research at Ispra, one of the EEC’s official joint research centres, and another $3 millions a year in indirect research with universities and other independent bodies.

D) be introduced

Passage Two Questions 62 to 66 are based on the following passage.

第62题：

he food we eat and of raw materials for many industrial processes, agriculture is clearly an important area of the economy. But the industrial performance of agriculture (the relative efficiency of agricultural production compared to other areas in the economy) is even more important than this. For in nations where the productivity of farmers is low, most of the working population is needed to raise food and few people are available for the production of investment goods or for other activities required for economic growth. Indeed, one of the factors related most closely to the per capita income (人均收入) of a nation is the fraction of its population engaged in farming. In the poorest nations of the world more than half of the population lives on farms. This compares sharply with less than 10 percent in western Europe and less than 4 percent in the United States.

In short, the course of economic development in general depends in a fundamental way on the performance of farmers. This performance, in turn, depends on how agriculture is organized and on the economic environment, or market structure, within which it functions. In the following pages the performance of American agriculture is examined. It is appropriate to begin with a consideration of its market structure.

第26题：This passage is most probably ________.

A) a news item

B) part of an introduction to a book

C) part of a lecture

D) an advertisement

the move. In unheard-of numbers, people of all ages are exercising their way to better health. According to the latest figures, 59 percent of American adults exercise regularly-up 12 percent from just two years ago and more than double the figure of 25 years ago. Even non-exercisers believe they would be more attractive and confident if they were more active.

It is hard not to get the message. The virtues of physical fitness are shown on magazine covers, postage stamps, and television ads for everything from beauty soaps to travel books.

Exercise as a part of daily life did not catch on until the late 1960s when research by military doctors began to show the health benefits of doing regular physical exercises. Growing publicity (宣传) for races held in American cities helped fuel a strong interest in the ancient sport of running. Although running has leveled off in recent years as Americans have discovered equally rewarding-and sometimes safer-forms of exercise, such as walking and swimming, running, remaining the most popular form. of exercise.

As the popularity of exercise continues to mount, so does scientific evidence of its health benefits. The key to fitness is exercising the major muscle groups vigorously (强有力的) enough to approximately double the heart rate and keep it doubled for 20 to 30 minutes at a time. Doing such physical exercises three times or more a week will produce considerable improvements in physical health in about three months.

第36题：According to the passage, what was the percentage of American adults doing regular physical exercises two years ago？

A) About 70%

B) Almost 50%

C) Nearly 60%

D) More than 12%
