Recently, several thousand computers in the United States were attacked by a virus. The co

mputers were slowed or shut down. But no information was lost. A computer virus is similar to a biological virus--an organism (生物体) that can harm the human body. A computer virus is a series of electronic commands that can harm a computer or the information in the computer. It infects the device (设备) secretly. It tells the computer to do something the computer's owner does not want it to do. For example, a virus could enter a bank's computer system. It might tell the system to destroy all information about money belonging to everyone with the first name United States several months ago. The virus was created by a university student studying computer science. The computers affected by the virus were in major universities, government agencies (政府机关) and private (私人) companies. They were part of a United commands in a computer at his school. The computer sent the commands to other computers through the linked telephone lines.

The virus told each computer to make many copies of itself. Within a few minutes, all the computers' power was being used to make copies of the virus. The computer could do no other work. It finally slowed down greatly, or simply stopped working. Computer experts spent many days trying to destroy the virus in the computer system.

The experts agree the virus could have been much worse. They say it could have sent orders to destroy huge amounts of electronic information.

Many experts believe, the recent computer virus showed the need for better computer security (安全). But that is a problem. The affected system provides a free exchange (交换) of ideas and information among universities, private companies and government offices. Increasing security too much would destroy this exchange. It would slow progress on many important research projects.

Which of the following statements is true？

A．Many computers were attacked by a virus in the U. S.

B．Many computers attacked by a virus in the U.S. lost their information.

C．A computer virus can harm human body.

D．A computer virus can help the computer owner do many things.

Next time you feel the flu coming on, think twice before reaching for painkillers—they cou

ld do more【C1】______than good. With the flu season【C2】______way across Europe and North America, millions will be taking flu【C3】______, which commonly include painkillers. The general【C4】______advice in the UK and the US is to take painkillers. But although painkillers can make you feel better they also lower fever, which can make the virus【C5】______.

Fever is thought to be a【C8】______against viruses, because many viruses find it hard to【C9】______above our normal 37 °C. Some studies have shown that lowering fever may【C10】______virus-related infections and increase the amount of virus we can【C11】______on to others. To find out what【C12】______this might have on a flu epidemic, David Earn and his colleagues【C13】______to a 1982 study which showed that ferrets, a【C14】______animal model for human flu produced more【C15】______flu virus if their fevers were lowered with painkillers. Earns team used these findings to estimate how much more virus people with【C16】______flu might produce if their fevers were【C17】______. With the help of a mathematical model, Earns team【C18】______their estimates to the number of people a year in the US who get flu,【C19】______fever and take the drugs. They found that painkillers as used in the US could be increasing the【C20】______of ordinary winter flu by up to 5 per cent.

第10题

As in most ethical situations, making a true or false promise involves other people. Almos

t every time we ask "What should I do？" we are aware that other people are involved in our behavior. Why should someone ask himself before making a false promise, "Is it right？" It may be that he is afraid of being found out. He may, however, wonder whether it is fair to the other person. How we relate ourselves to others or how we behavior. affects others makes up most of the subject matter of ethics. Being aware of others is more than wondering how our actions will affect them; we are also Concerned about how the behavior. of others will affect us. There is no satisfactory way for us to avoid the presence of other people. The most we can do is try to arrange the rules of behavior, of ethics, in order to reduce the amount of friction and conflict and thereby achieve the greatest amount of harmony. Whether our actions are right and good will depend to a great extent on the effect they will have on others. Actions such as telling a falsehood, stealing, injuring, and killing are considered wrong most of the time because they result in varying degrees of harm to someone. They also produce reactions from the victims, who in effect say, "If it is right for you to do that to me, then I will not hesitate to do the same thing to you."
