　　The Chinese soon attacked back.

　　On April 2, Chinese hackers invaded two Government websites over the weekend, forcing the Department of labor and the Department of the Health and Human Services to shut down their sites for a short time.

　　The US Department of labor went off line for a few hours after a page in its website was changed to display a picture of Wang Wei, the Chinese pilot who died in the collision.

　　9 There were two interesting news items () in the paper a few years ago . One was about a man who received a bill from the telephone company for £999,999—for three month! The other was about a man who received £2,000 a month ---for doing nothing.

　　The connection between the two news items is simple: computer – the best invention of the 20th century. The telephone bill came from a computer which made a terrifying mistake that was only £23.36. The other item was not so amusing. A man walked into the unguarded computer room of a large packaged food company (袋裝食品生產(chǎn)公司) and expertly programmed the computer (給計(jì)算機(jī)編程序) to pay him £2,000 a month for raw meat which he “supplied” to the company. Of course he never sent the meat, but he certainly received the money. The computer wrote out a bill, and even “signed”it. It was only a random (隨便的) check that uncovered the trick. It could be happening in thousands of other companied all over the world.

　　Computers are not the magical workers that some people say they are. They make mistakes, they’re sometimes slower than human beings and they’re easily fooled. The US used to conscript (征兵) people with the help of a computer. The army sent out a card, which had to be filled in and sent back. It was easy to avoid being called up simply by spreading candle-waxon on the card. The computer couldn’t read the card and did nothing with it.

　　It’s in our everyday life that computers cause many problems. Let’s get back to using people instead of computers, before a mistake that we can’t put right.

　　The writer’s main idea is __________.

　　A we’d better use people instead of computers in our everyday life.

　　B we should not use computers because they always make mistakes

　　C computers are widely used in our everyday life

　　D if we want to work well, don’t use the computers.
