问题     In many parts of the world there is a debate about whether children should use pocket calculators in math lessons. They help children work faster and pass examinations. But critics say that they make the subject too easy.
    This concern that technology is doing much of our thinking for us cuts across many areas. People who use computers for many years find that their handwriting had become worse. Artists paint pictures using computer software rather than learning to draw and paint. Tennis players no longer try to outwit (在智慧上战胜) their opponents. Advances in tennis racket technology make it easier to just blast (猛击) the ball past them.
    Technology used to be about freeing people from boring physical labor like washing clothes. Now it is taking over increasingly complicated mental functions. Analysts are also worried about the effect of media saturation (渗透). The idea is that a constant diet of television has made people too impatient to listen while things are explained to them. Television depends on pictures, preferably exciting ones. Events make better TV viewing than processes. Action comes before understanding. There is a tendency to replace long explanation of complicated events with simple summaries. The tendency is called dumbing down. Critics say that it has produced a post-literate generation of people. They are able to read and write and capable of thinking and understanding. But they prefer to let the television do these things for them.
    To avoid going down this path, it is necessary to remember that the mind is like a muscle. The more it is exercised, the stronger it gets. The easy way is not always the best.
It is implied in Para. 3 that      .
选项 A、too much exposure to TV viewing is negative to people’s intellectual well-being
B、too much exposure to TV viewing makes people simple-minded
C、TV attracts people with exciting pictures
D、TV keeps people informed about current events
答案A
解析 第三段第二句话Now it is taking over increasingly complicated mental functions.(如今，科技正在接管越来越多的复杂的智力劳动。)为该段的中心句，后面的陈述都围着此句展开。细读此段可知，该段中叙述的是电视的负面影响，可以推断出A正确。
