e, there is a boom in Internet-based instruction. In just a few years, 34 percent of American universities have begun offering some form. of distance learning （DL）, and among the larger schools, it's close to 90 percent. If you doubt the popularity of the trend, you probably haven't heard of the University of Phoenix. It grants degrees entirely on the basis of online instruction. It enrolls 90,000 students, a statistic used to support its claim to be the largest private university in the country.

While the kinds of instruction offered in these programs will differ, DL usually signifies a course in which the instructors post syllabi （课程大纲）, reading assignment, and schedules on Websites, and students send in their assignments by e-mail. Generally speaking, face-to-face communication with an instructor is minimized or eliminated altogether.

The attraction for students might at first seem obvious. Primarily, there's the convenience promised by courses on the Net: you can do the work, as they say, in your pajamas （睡衣）. But figures indicate that the reduced effort results in a reduced commitment to the course. While dropout rate for all freshmen at American universities is around 20 percent, the rate for online students is 35 percent. Students themselves seem to understand the weaknesses inherent in the setup. In a survey conducted for eCornell, the DL division of Cornell University, less than a third of the respondents expected the quality of the online course to be as good as the classroom course.

Clearly, from the schools' perspective, there's a lot of money to be saved. Although some of the more ambitious programs require new investments in servers and networks to support collaborative software, most DL courses can run on existing or minimally upgraded （升级） systems. The more students who enroll in a course but don't come to campus, the more school saves on keeping the lights on in the classrooms, paying doorkeepers, and maintaining parking lots. And, while there's evidence that instructors must work harder to run a DL course for a variety of reasons, they won't be paid any more, and might well be paid less.

C．Rebecca draws on a lot of online materials for her writing.

Passage 1

Since early times, people have been fascinated with the idea of life existing somewhere else besides earth. Until recently, scientists believe that life on other planets was just a hopeful dream. But now they are beginning to locate places where life could form. In 1997, they saw evidence of planets near other stars like the sun. But scientists now think that life could be even nearer in our own solar system. One place scientists are studying very closely is Europa, a moon of Jupiter. Space probes have provided evidence that Europa has a large ocean under its surface. The probes have also made scientists think that under its surface Europa has a rocky core giving off volcanic heat. Water and heat from volcanic activity are two basic conditions needed for life to form. A third is certain basic chemicals such as carbon, oxygen and nitrogen. Scientists believe there might be such chemicals lying at the bottom of Europa’s ocean. They may have already created life or may be about to. You may wonder if light is also needed for life to form. Until recently, scientists thought that light was essential. But now, places have been found on earth that are in total blackness such as caves several miles beneath the surface. And bacteria, primitive forms of life, have been seen there. So the lack of light in Europa’s sub-surface ocean doesn’t automatically rule out life forming.

根据材料回答第 26～28 题。第 26 题 What did scientists once believe according to the passage？

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.

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.
