A Census Bureau （人口调查局) survey released Thursday shows a college graduate can expect

A Census Bureau (人口调查局) survey released Thursday shows a college graduate can expect to earn $ 2. 1 million working full-time between 25 and 64, which demographers (人口学家) call a typical work-life period. A master' s degree-holder is projected to earn 2.5 million, while someone with a professional degree, such as a doctor or lawyer, could make even more--$ 4.4 million. In contrast, a high school graduate can expect to make $ 1.2 million during the working years, according to the bureau report that tracked the influence of education on lifetime earnings.

Not all students look at college as an investment, "but I am sure parents do," said Jacque line King, policy analyst with the American Education Council, a higher education advocacy (拥护) group. "The college is to convince those high school students on the margins that it is really worth their time to go to college." Kevin Malecek, a graduate student in American poli tics at American University in Washington said most of his classmates find higher education to be worth the time and financial promise. "They go to every single class, and they are trying to get the most out of their own dollar," he said. The survey was conducted between March 1998 and March 2000. All estimates are based on 1999 salaries and probably will increase as salaries rise over time, Census Bureau analyst Jennifer Day said. The estimates do not account for inflation (物价上涨) or for differences in the earning potential of various fields of study. For example, people with computer science degrees tend to earn more than those with social work degrees.

The phrase "students on the margins" in Line 3 of Paragraph 2 most probably refers to ______.

A．students Who actually regard higher education as an investment

B．students who can't afford the money to go to college or university

C．students who can't go to college because they have failed in the college entrance examination

The United States Census Bureau recently released a new report on the situation．____(2)．

Recently a newspaper has reported that salaries for college students are equivalent to wages for migrant workers. Apparently this comparison is too simple and superficial.

Space is a dangerous place, not only because of meteors but also because of rays from the sun and other stars. The atmosphere again acts as our protective blanket on earth. Light gets through, and this is essential for plants to make the food which we eat. Heat, too, makes our environment endurable. Various kinds of rays come through the air from outer space, but enormous quantities of radiation from the sun are screened off. As soon as men leave the atmosphere they are exposed to this radiation but their spacesuits or the walls of their spacecraft, if they are inside, do prevent a lot of radiation damage.

Radiation is the greatest known danger to explorers in space. The unit of radiation is called "rem". Scientists have reason to think that a man can put up with far more radiation than 0.1 ream without being damaged; the figure of 60 rems has been agreed on. The trouble is that it is extremely difficult to be sure about radiation damage--a person may feel perfectly well, but the cells of his or her sex organs may be damaged, and this will not be discovered until the birth of deformed (畸形的) children or even grandchildren. Missions of the Apollo flights have had to cross belts of high radiation and, during the outward and return journeys, the Apollo crew accumulated a large amount of reams. So far, no dangerous amounts of radiation have been reported, but the Apollo missions have been quite short. We simply do not know yet how men are going to get on when they spend weeks and months outside the protection of the atmosphere, working in a space laboratory. Drugs might help to decrease the damage done by radiation, but no really effective ones have been found so far.

According to the first paragraph, the atmosphere is essential to man in that ______. ( )

A．it protects him against the harmful rays from space

B．it provides sufficient light for plant growth

C．it supplies the heat necessary for human survival

D．it screens off the falling meteors
