Of course he never sent the meat，but he certainly r
6、eceived the money. The computer wrote out a bill，and even “signed (署名) it. It was only a random(随便的) check that uncovered the trick. It could be happening in thousands of other companies all over the world.Computers are not the magic workers that some people say they are. They make mistakes，they are
7、 sometimes slower than human beings and they are 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.

12、ic from the Web. If it couldnt be free, then they wanted it “new” or at least at a low price.
