Directions:
Read the following three texts. Answer the questions on each text by choosing A, B, C or D. Mark your answers on the ANSWER SHEET by drawing a thick line across the corresponding letter in the brackets.
After a busy day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the previous day. The rest that you get while sleeping enables your body to prepare itself for the next day.
There are four levels of sleep, each being a little deeper than the one before. As you sleep, your muscles relax little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts back and forth from one level of sleep to the other.
Although your mind slows down, from time to time you will dream. Scientists who study sleep state that when dreaming occurs, your eyeballs begin to move more quickly (Although your eyelids are closed). This stage of sleep is called REM, which stands for rapid eye movement.
If you have trouble falling asleep, some people recommend breathing very deeply. Other people believe that drinking warm milk will help make you drowsy. There is also an old suggestion the counting sheep will put you to sleep!

参考答案：
46.A 文章的第一段谈到睡眠能使身体健康， 第二段、第三段谈到睡眠的几种状态，最后一段谈到很快入睡的几种方法。因此整篇文章都围绕睡眠而谈， 因此A为正确答案。
47.D. drowsy :瞌睡的.， 想睡的。 因为上一句的意思是：“如果你睡觉有困难的话， 有人建议慢慢的深深呼吸。”紧接着作者说：“另外一些人认为喝热牛奶能使你…, 根据上下文应该选”瞌睡的“， 因此只有D 最符合题意。sick : 有病的;stand up :起立。 asleep : 睡着的。
48.B 答案在文章的第一段第二句话：“Sleep is necessary for good health.”意思是：“睡眠有利于身体健康。”因此本句的意思是睡眠不足有害健康。只有B最符合题意。
49.D 答案在第三段第二句话：“Scientists who study sleep state that when dreaming occurs your eyeballs begin to move more quickly.”意思是：“研究睡眠的科学家指出一个人做梦的时候眼球移动速度加快。”因此正确答案为D.
50.D 文章中没有谈到成年人的平均睡眠时间。
