答案解析

【设题处】细节处设题
【解析】选[C]。由选项可知此题考查被研究的孩子们的共同点。通过寻读，文章第二段第二句提到调查中的孩子都是1992年3月一个星期内出生的，调查追踪了他们从出生到上学的情况，所以这些孩子的年龄是一样的，故答案为 [C]。[A]和[D]属于对第二段第二句话的过度推理；第三段中说到，调查表明，家庭的财务状况会影响到父亲对孩子的关注程度，这说明接受调查的孩子所处的社会阶层是不一样的，由此可排除[B]。

3 Questionsare based on the following passage.
　　Worry is one of the most common forms of emotional distress in our culture. Almost everyone spends a considerable amount of present moments worrying about the future. And virtually all of it is for nothing. Obsessive (过分的) worry will never make things any better. In fact, such worry will very likely help you to be less effective in dealing with the present.
　　In order to reduce worry, it is necessary to understand the subconscious psychological "
payoffs" for choosing to worry in the first place. "I can't do a thing. I'm too worded about... " This is a common sorrow, and one with a payoff that keeps you standing still and avoiding the risk of action. Clearly, it is easier, if less rewarding, to worry than to be an active.
　　If you weigh too much, you may eat more when you worry; hence, you have a good reason for hanging on to the worry behavior. Similarly, you may find yourself smoking more in troublesome situations, and can use the worry to avoid giving up smoking. The same anxious reward system also applies to health. It may be easier for you to worry about chest pains than to risk finding out the truth, and then having to deal directly with yourself.
　　Worry can bring a lot of diseases such as tension headaches and backaches. While these may not seem to be payoffs, they do result in considerable attention from others and justify much self-pity as well. And some people would rather be pitied than fulfilled.
　　Now that you understand the psychological support system for neurotic worry, you can begin to devise some measures for reducing the number of troublesome worry bugs that breed in this incorrect zone.
　　Begin to view your present moments as times to live, rather than times to worry about the future. When you" catch yourself worrying, ask yourself, "What am I avoiding now by using up this moment with worry?" Then begin to attack whatever you're avoiding. "The passage is mainly concerned with _________

A．the negative effects of worry

B．the positive effects of worry

C．the causes of worry

D．the diseases caused by worry
