问题     Insomnia (失眠) is the inability to sleep calmly and relaxedly. It is a problem to nearly everyone at some time. A person may be awake for an hour in the middle of the night and then, next morning, may feel that he hardly slept all night. Normally, worry about not getting enough sleep is the worst aspect of most insomnia. If insomnia occurs repeatedly, it is important to find its possible causes and try to correct them.
    Any of simple factors may make one feel difficult to fall asleep. His mattress (床垫) may be too soft or too hard. If there are too many blankets (毯子) on a hot night, he may be too warm; if the mattress is too light he may feel cold during the night. The bedroom itself may be overheated or too cold. If it is not dark enough, or too noisy, this may cause difficulty in sleeping. Eating shortly before going to bed may also be responsible for insomnia. Drinking tea or coffee can also make people awake.
    The cause of insomnia may be easy to correct. The sufferer should check the mattress, and bedroom temperature, and make any necessary changes. He should relax for an hour or two before bedtime, perhaps by reading a book, watching television or taking a warm bath. If he wakes during the night he should try turning on the light and reading for a while. Taking warm milk and a biscuit or two may be helpful.
According to the writer, the most serious aspect of insomnia is generally ______.
选项 A、the repeated occurrence of insomnia
B、the worry about less time for sleep
C、the difficulty in changing it
D、the tiredness from the insomnia
答案B
解析 细节理解题。本题询问作者认为失眠最严重的方面一般是什么。根据文章第一段第四句话可知担心睡眠不足是多数失眠最严重的方面，故选项B(担心睡的时间不够)为正确答案。由于失眠最糟的方面是担心睡眠不足，所以如果反复失眠就要找出原因，因此，选项A(反复出现失眠)不符合题意。选项C(改变失眠现象很困难)与选项D(失眠造成的疲倦)在文章中均未提及，故可以排除。
