On October 12, 1989, some Chinese scientists were working at the computers to look for the information they needed. Suddenly they saw a lot of very bright spots crossing the computer’s screens. At the same moment the computers were working much slower. To find out what was happening they stopped their work to look over some parts of the computers. To their surprise, they found out that most of their stored information was got rid of by computer viruses(病毒)! It’s clear that all these computers had been infected(传染) by computer viruses.
It is said that the computer viruses were made by a group of young men interested in playing tricks. They all had a lot of computer knowledge. They made the viruses just to show their cleverness. This kind of computer viruses is named Jerusalem Viruses. These viruses can stay in computer for a long time. When the time comes they will hit the computers by lowering the functions, breaking their usual programs or even getting rid of all the information.
We now come to know that Jerusalem Viruses often hit computers on Friday and that they are visiting a lot of computers. Among the countries that had computer viruses last year are Britain, Australia, Switzerland and the US. But till now, how to get rid of the terrible viruses is still a problem.

Passage 2
If you are like most people, your intelligence various from season .You are probably a lot sharper in the spring than you are at any other time of year. A noted scientist, Ellsworth Huntington (1876-1947), concluded from other men’s work and his own among the people in different climates that climate and temperature have a definite effect on our mental abilities.
He found that cool weather is much more favorable for creative thinking than in summer heat. This does not mean that all people are less intelligent in summer than they are during the rest of the year. It does mean, however, that the mental abilities of large numbers of people tend to be lowest in summer.
Spring appears to be the best period of the year for thinking. One reason may be that in the spring man’s mental abilities are affected by the same factors that bring about great changes in all nature.
