[单项选择]Passage One
Between now(June) and Labor Day, millions of Americans will offer up their bodies to the sun’s rays. A tan indicates health and beauty, and most sun worshippers will sacrifice a lot to achieve it. With each hour, the sun’s ultraviolet radiation produces irreversible(不可逆的) damage, hastening the development of unsightly wrinkles.

An estimated 400,000 new cases will be detected this year in the United States, and almost all of them can be blamed on overexposure to the sun. Fortunately, most of these cancers are highly curable. But they can be disfiguring and take time to treat.
For that reason, sun worshippers should treat deity with a good deal of awe. Sunburn, of course, is the initial hazard posed by UV radiation. Prolonged exposure to UV, however, interferes with the production of collagen

[单项选择]Passage One
There is a difference between science and technology. Science is a method of answering theoretical questions; technology is a method of solving practical problems. Science has to do with discovering the facts and relationships between observable phenomena in nature and with establishing theories that serve to organize these facts and relationships; technology has to do with tools, techniques, and procedures for implementing the finding of science.
Another distinction between science and technology has to do with the progress in each.
Progress in science excludes the human factor. Scientists, who seek to comprehend the universe and know the truth within the highest degree of accuracy and certainty, cannot pay attention to their own or other people’s likes or dislikes or to popular ideas about the fitness of things.

Standards of living improved
A. believed that they were very much the same as their equals some two thousand years before.
B. probably thought that great changes had occurred since Cicero.
C. felt that qualitative changes had occurred in the last two thousand years.
D. believed in the efficacy of slavery.

[单项选择]Passage 2

Between 1833 and 1837, the publishers of a "penny press" proved that a low-priced paper, edited to interest ordinary people, could win what amounted to a mass circulation for the times and thereby attract an advertising volume that would make it independent. These were papers for the common citizen and were not tied to the interests of the business community, like the mercantile press, or dependent for financial support upon political party allegiance. It did not necessarily follow that all the penny papers would be superior in their handling of the news and opinion functions. But the door was open for some to make important journalistic advances.
The first offerings of a penny paper tended to ’be highly sensational; human interest stories overshadowed important news, and crime and sex stories were written in full detail. But as t
