[originaltext] There’s no doubt that the computer has enlarged man’s working

There’s no doubt that the computer has enlarged man’s working capacity as well as his intellectual capacity enormously. But it brings with it dangers to match the benefits. Now by this, I mean the dangers to physical and mental well-being of the people who work at computer terminals, not the dangers to personal privacy or national or industrial security.
    There’s a very alarming set of statistics which comes from a survey done in the UK on 800 pregnant women, who happened to use computer terminals for a major part of their working days. In no less than 36％ of the subjects there were some severe abnormalities during the pregnancy, enough to make a termination necessary. Now these figures compare significantly with a control group of pregnant women of the same age who did not work with computer terminals. The rate of severe abnormalities in their case was only 16％. This survey confirms similar investigations carried out in Denmark, Canada, Australia and the US.
    Ironically, it seems that it’s not only those who work with computers are at risk. There’s perhaps more danger for people who use computers for interest or pleasure in their own homes. Most people get so fascinated by what they are doing that they stay in front of the screen for hours.
    Now, no one yet has a clear idea about the exact connection between working or playing with computer terminals and the problems with physical and mental well-being, but the figures at least suggest that there’s a cause for alarm.
    Questions 12 to 15 are based on the passage you have just heard.
    12. What is the passage mainly about?
    13. What does the survey done in the UK suggest?
    14. Which country didn’t carry out a research concerning computer using and abnormalities?
    15. What do we know about the current studies on the dangers of using computers?
