6、问题:By almost any measure, 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 closer 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 assignments, 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 rates 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 the 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. What is the most striking feature of the University of Phoenix?
选项：
A:It boasts the largest number of students on campus.
B:All its courses are offered online.
C:Its online courses are of the best quality
D:Anyone taking its online courses is sure to get a degree.
答案: 【All its courses are offered online.】

8、问题:Many students take Internet-based courses mainly because they can __.

A:save a great deal on traveling and boarding expenses
B:select courses from various colleges and universities
C:work on the required courses whenever and wherever
D:earn their academic degrees with much less effort
答案: 【work on the required courses whenever and wherever】

9、问题:What accounts for the high drop-out rates for online students?
选项：
A:There is no mechanism to ensure that they make the required effort.
B:There is no strict control over the academic standards of the courses.

D:Lack of classroom interaction reduces the effectiveness of instruction.

6、问题:Lead deposits, which accumulated in soil and snow during the 1960’s and 70’s, were primarily the result of leaded gasoline emissions originating in theUnited States. In the twenty years that the Clean Air Act has mandated unleaded gas use in theUnited States, the lead accumulation worldwide has decreased significantly.A study published recently in the journal Nature shows that air-borne leaded gas emissions from theUnited Stateswere the leading contributor to the high concentration of lead in the snow in Greenland. The new study is a result of the continued research led by Dr. Charles Boutron, an expert on the impact of heavy metals on the environment at the National Center for Scientific Research inFrance. A study by Dr. Boutron published in 1991 showed that lead levels in arctic (北极的) snow were declining.In his new study, Dr. Boutron found the ratios of the different forms of lead in the leaded gasoline used in theUnited Stateswere different from the ratios of European, Asian and Canadian gasoline and thus enabled scientists to differentiate (区分) the lead sources. The dominant lead ratio found in Greenland snow matched that found in gasoline from theUnited States.In a study published in the journal Ambio, scientists found that lead levels in soil in the Northeastern United States had decreased markedly since the introduction of unleaded gasoline.Many scientists had believed that the lead would stay in soil and snow for a longer period.The authors of the Ambio study examined samples of the upper layers of soil taken from the same sites of 30 forest floors in New England, New York and Pennsylvania in 1980 and in 1990. The forest environment processed and redistributed the lead faster than the scientists had expected.Scientists say both studies demonstrate that certain parts of the ecosystem (生态系统) respond rapidly to reductions in atmospheric pollution, but that these findings should not be used as a license to pollute.The study published in the journal Nature indicates that __.
选项：
A:the Clean Air Act has not produced the desired results
B:lead deposits in arctic snow are on the increase
C:lead will stay in soil and snow longer than expected
D:the US is the major source of lead pollution in arctic snow
答案: 【the US is the major source of lead pollution in arctic snow 】

7、问题:Lead accumulation worldwide decreased significantly after the use of unleaded gas in the US __.
选项：
A:was discouraged
B:was enforced by law
C:was prohibited by law
D:was introduced
答案: 【was enforced by law 】

8、问题:How did scientists discover the source of lead pollution in Greenland?
选项：
A:By analyzing the data published in journals like Nature and Ambio.
B:By observing the lead accumulations in different parts of the arctic area.
C:By studying the chemical elements of soil and snow in Northeastern America.
D:By comparing the chemical compositions of leaded gasoline used in various countries.
答案: 【By comparing the chemical compositions of leaded gasoline used in various countries. 】

9、问题:The authors of the Ambio study have found that __.
选项：
A:forests get rid of lead pollution faster than expected
B:lead accumulations in forests are more difficult to deal with
C:lead deposits are widely distributed in the forests of the US
D:the upper layers of soil in forests are easily polluted by lead emissions

10、问题:It can be inferred from the last paragraph that scientists __.
选项：
A:are puzzled by the mystery of forest pollution
B:feel relieved by the use of unleaded gasoline
C:still consider lead pollution a problem
