US college students are burdened, with credit card (信用卡)debt, according to a study published Tuesday, and the problem can be serious－ranging from more drop-outs, to future employment problems and even self-murder. The study, by Georgetown University sociologist (社会学家) Robert Manning, blamed credit card issuers for actively targeting students and colleges for allowing them to do so. "The unrestricted selling of credit cards in universities or colleges is so aggressive that it now forms a greater threat than alcohol or sexual diseases," Manning told a news conference in Washington. "If we do not quickly deal with this serious problem, the matter will continue to get worse, with social consequences far more tragic (悲剧的) than mere dollars and cents. "
Based on hundreds of face-to-face interviews and surveys with students, Manning concluded both the number with credit card debt and their indebtedness had been "underreported" in previous studies－which failed to reflect the "survival strategies" many used to deal with their debts. These included the use of federal student loans to pay off credit cards, effectively shifting the debt, appealing to parents for loans, reducing course work hours to increase time at paid jobs, or even dropping out altogether to work full time.
"Official drop-out rates include growing numbers of students who are unable to cope with the stress of their debts and / or part time jobs for servicing their credit cards, " the study said. "Students credit card debts are examined during the employment process and may be an important factor in evaluating future employees," it noted. O’Donnell and Manning agreed students should bear some responsibility for reckless use of credit, but said credit card companies also had to be held responsible for making it so easy for them to get into debt. Manning said one of the most troublesome aspects of the student credit card issue was "the seduction (诱惑) of college and university officials by the credit card industry".

Insurance companies provide a service to the community by protecting it against expected and unexpected disasters. Before an insurance company will agree to insure anything, it collects accurate figures about the risk. It knows, for example, that the risk of a man being killed in a plane accident is less than the risk he takes in crossing a busy road. This enables it to quote(报价) low figures for travel insurance. Sometimes the risk may be high, as in motor-racing or mountaineering. Then the company charges a much higher price. If too many climbers have accidents, the price rises further. If the majority of climbers fall off mountains, the company will refuse to insure them.
An ordinary householder may wish to protect his home against fire or his property against burglary(入室行窃). A shopkeeper may wish to insure against theft. In normal cases, the company will check its statistics and quote a premium(保险费). If it is suspicious(可疑的), it may refuse to quote. If it insures a shop and then receives a suspicious claim, it will investigate the claim as a means of protecting itself against false claims. It is not unknown for a businessman in debt to burn down his own premises so that he can claim much money from his insurance company. He can be sure that the fire will be investigated most carefully. Insurance companies also accept insurance against shipwreck or disaster in the air. Planes and ships are very expensive, so a large premium is charged, but a reduction is given to companies with an accident-free record.
Every week, insurance companies receive premium payments from customers. These payments can form a very large total running into millions of dollars. The company does not leave the money in the bank. It invests (投资) in property, shares (股票) ,farms and even paintings and stamps. Its aim is to obtain the best possible return on its investment. This is not as greedy as it may seem since this is one way by which it can keep its premiums down and continue to make a profit while being of service to the community.

A．insurance companies protect the community against disasters

B．insurance companies often collect accurate figures about the risk

The storage of classified (分类的) research at all 24 labs run by the US Department of Energy was shut down this week after officials decided that the security (安全) problems recently found at the Los Alamos National Laboratory in New Mexico might also exist elsewhere.
Several computer disks went missing at Los Alamos earlier this month, forcing Energy Secretary Spencer Abraham to stop all work at the lab until the problems are found out. As of 26 July, two missing disks had still not been found, and 15 employees had been suspended in connection with the disappearance.
Now all energy labs will stop doing classified research that involves(需要) removable storage devices --- such as computer disks --- until all the devices are given explanation for and new procedures are in place for monitoring their handling by laboratory employees.
"While we have no evidence that the problems being investigated are present elsewhere, we have a responsibility to take all necessary action to prevent such problems, "Abraham said on 23 July.
The shut-down isn't quite as dramatic（惊人的）as it sounds, experts say. Only two labs will be seriously affected: Sandia National Laboratories in Albuquerque, New Mexico, and Lawrence Livermore National Laboratory in California. Together with Los Alamos, these two labs conduct the most part of the country's nuclear weapon programmes. At Livermore, 876 employees will be suspended during the storage of some 12,000 items of classified removable material.
At other labs, far fewer people will be affected. "The impact (影响) should be the smallest," says Martha Krebs, former director of the energy department's science office.
Why was the storage of classified research at all 24 labs shut down?

A．Because the security problems might be present elsewhere.

B．Because the security problems existed elsewhere.

C．Because two missing computer disks had still not be found.

D．Because officials decided to stop doing such research.

How many labs conduct the country's nuclear weapon programmes according to the text?

A．About 24.

B．Only 2.

C．More than 2.

D．Over 15.

The underlined word "suspended"in the second paragraph probably means "______”.

A．hung from above

B．stopped from holding a position

C．doubted

D．fired

It can be inferred from the text that _____.

A．the computer disks must have been stolen by terrorists

B．the people living in the United States have little security

C．the United States is a country whose security is very bad

D．the missing of the computer disks caused great fear among Americans
