单选题 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 cheek 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.

单选题 According to the writer, the most serious aspect of insomnia is generally ______.
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

【正确答案】 B

【答案解析】[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。

单选题 Which of the following might NOT cause insomnia according to the passage?
A. The over-softness of the mattress. B. The darkness in the bedroom.
C. Eating just before going to bed. D. Drinking tea before sleeping.

【正确答案】 B

【答案解析】[解析] 细节判断题。本题询问根据文章内容可知以下哪个选项可能不是导致失眠的原因。根据文章第二段的内容可知，导致失眠的因素很多，其中有一项是房间不够暗，也就是说如果房间黑暗则不会导致失眠。因此，选项B(房间黑暗)与文意不符，为符合题意的正确答案。
选项A(床垫过软)，选项C(睡前吃东西)与选项D(睡前喝茶)均符合文章第二段的内容，故不符合题意，为错误选项。

单选题 According to the passage, which of the following is NOT true about insomnia?
A. It is a kind of disease. B. It might occur to any person.
C. It may be easy to cure. D. Simple factors can lead to insomnia.

【正确答案】 A

【答案解析】[解析] 推理判断题。本题询问的是以下哪个选项是不正确的说法。根据整篇文章的内容可知文中并未提及失眠是一种疾病。此外，常识告诉我们失眠并不是一种疾病，而是一种非正常的状态。因此可以推断出选项A(失眠是一种疾病)为正确答案。
文章中第一段第二句话提到几乎每个人都会遇到失眠的问题；最后一段第一句话则表示导致失眠的因素不难矫正；第二段第一句话提到任何简单的因素都可能导致人们难以入睡，据此可以判断选项B(失眠可以发生在任何人身上)，选项C(失眠不难治愈)与选项D(简单的因素可以导致失眠)均是正确的说法，不符合题意，可以排除。

单选题 The method mentioned above in treating insomnia is to ______.
A. eat appropriate amount of food B. take a walk before going to bed
C. change its causes directly D. have more reading before sleeping

【正确答案】 C

【答案解析】[解析] 推理判断题。本题询问的是文中提到治疗失眠的方法是什么。文章第二段主要讲的是哪些因素可以导致失眠，第三段则是针对这些因素可以采取的应对措施。由此可以判断治疗失眠的方法主要是矫正导致失眠的因素，故选项C(直接改变导致失眠的因素)符合题意，为正确答案。
本题正确答案以外的其他选项都比较具有迷惑性。选项A(吃适量的食物)与选项D(睡前多阅读)看似符合文章最后一段的内容，其实不然。它们与最后一段的内容存在偏差，而且它们是具体措施，并不是具有指导性的方法。而选项B(睡前散步)在文中并未提及。

根据文章最后一段可知，选项A(看书)，选项B(看电视)与选项D(洗热水澡)都是能够让失眠患者在睡前放松自己的做法，不符合题意。
