Part I: The text below has 10 mistakes. Read it carefully and pick out the mistakes. WHY I DISLIKE COMPUTERS Almost everyone says that computers are wonderful and that they are changing our own lives for the better by making everything faster and more reliable, but I am not so much sure that this is the case. The other day I was standing in large department store until waiting to pay for a couple of films for my camera when the assistant announced that the computer which controlled the till it had stopped working. I did not think this was a big problem and I set myself off to find another counter, but of course, all the machines are one part of the same system. So there we were: a shop full of customers, money at the ready, waiting to make our purchases, but it was quite clear that none out of the assistants knew what to do. They were not allowed to take our money and give to customers a written receipt, because the sales would not then have been recorded on the computer system. In the end, like with many other people, I left my shopping on the counter and walked out. Don’t you think so that’s ridiculous? It would never have happened before computers, and that, for me, is all the problem: we are beginning to depend on these machines for so completely that we simply cannot mange without them any more.
