The Internet is a way of life for US college students. A recent survey by Harris Interactive and 360 youth found that 93 per cent of American college students visit the Internet, and this market is expected to grow from 15.2 million in 2003 to 16.4 million in 2007.
That is slow but it could be the result of the already high number of Internet college users. About 88 per cent of American college students own a computer, and more than half have broadband (宽带) connections. Furthermore, 67 per cent own cell phones and 36 per cent use their mobile devices to visit the Internet.
Study findings show that 42 per cent go online mainly to communicate socially, and 72 percent of college students check emails at least once a day, with 66 per cent using at least two email addresses. The most popular online social activity is sending messages to friends or family, with 37 percent of college students saying they do so.

A. waste much time visiting the Internet

C. lead an exciting life by using the Internet
D. don’t have to learn their lessons in the classrooms
[单项选择]People once widely believed that intelligent life existed on Mars. The 19th-century discovery of what appeared to be geometric designs cut across the surface was taken as evidence. The lines were thought to have been a system of canals that had been built to irrigate the surface. It is now clear that the "canals"—perhaps the most spectacular geologic features of Mars—are natural valleys where ancient rivers once flowed.
Another fragmented idea concerns the planet’’s seasonal changes in color. Once attributed to the rapid spread of some life-form, these shifts are now known to develop from the movement of fine dust in the atmosphere.
By the close of the 20th century none of the many experiments conducted by spacecraft had ever found persuasive evidence of life. Nevertheless, speculation continued over the existence of some form of life, in either the present or past. In 1996 scientists discovered organic compounds and minerals in a meteorite (陨石), consisting of Martian rock, t
A. The meteorite containing organic compounds is part of Mars.
B. A Martian rock struck Earth about 11,000 years ago.
C. The organisms came back to life after the collision with Earth.
D. The inhabiting organisms appeared more than three billion years ago.
