Passage Two Questions 62 to 66 are based on the following passage.
第62题：
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 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.
第26题：The phrase “be brought forward” (Line 2, Para. 1) most probably means ________.
A) be expected
B) be completed
C) be advanced
D) be introduced
Why would things weigh only a quarter as much as they do at the surface of the earth if we took them 4 000 miles out into space？ The reason is this: All objects have a natural attraction for all other objects; this is called gravitational attraction, but this power of attraction between two objects gets weaker as they get farther apart. When the butter was at the surface of the earth, it was 4 000 miles from the centre (in other words the radius (半径) of the earth is 4 000 miles). When we took the butter 4 000 miles out, it was 8 000 miles from the centre, which is twice the distance.
If you double the distance between two objects, their gravitational attraction decreases (减少) two times two. If you treble (翻三倍) the distance, it gets nine times weaker (three times three). If you take it four times as far away, it gets sixteen times weaker (four times four) and so on.
第69题：The best title for this passage is ________.
[A] The Earth Weight
[B] Weight in Space
[C] Changing Weight on the Earth
[D] Weight on and off the Earth
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%
