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.
The expression "cuts across" (Line 1, Para. 2) most probably means      .
选项 A、affects
B、runs across
C、damages
D、results in
答案A
解析 可根据文章前两段来判断：第一段讲使用袖珍计算器不利于学生锻炼思考能力，第二段讲电脑及网球拍领域的新科技使人减少了锻炼自己思考能力的机会，可以判断出cuts across在句中是“影响到，进入到”的意思，因此答案为A
