Section ⅠUse of English
Sleep is divided into periods of so-called REM sleep, characterized by rapid eye movements and dreaming, and longer periods of non-REM sleep. 1   kind of sleep is at all well-understood, but REM sleep is 2   to serve some restorative function of the brain. The purpose of non-REM sleep is even more 3  . The new experiments, such as these 4  for the first time at a recent meeting of the Society for Sleep Research in Minneapolis, suggest fascinating explanations 5  of non-REM sleep.
For example, it has long been known that total sleep 6  is 100 percent fatal to rats, yet, 7 _examinations of the dead bodies, the animals look completely normal. A researcher has now
8   the mystery of why the animals die. The rats  9   bacterial infections of the blood, 10 their immune systems—the self-protecting mechanisrn against disease—had crashed.

一、文章结构总体分析
睡眠分为浅睡阶段和较长时间的深睡阶段。虽然人们对两个阶段的睡眠都不是十分了解,但是人们推测浅睡对大脑起修复作用。深睡的作用更令人难以理解。在最近睡眠研究协会的会议上,专家们首次描述的新实验,对非快眼动睡眠的作用进行了吸引人的阐释。因剥夺睡眠而死亡的老鼠的尸体检查发现,其免疫系统似乎已崩溃了。
二、 试题解析
1.[答案] B
[解析] 本题考核的知识点是:不定代词的用法。
空格上文提到,睡眠分为浅睡阶段和深睡阶段。因此空格处____ kind of sleep指的就是这两种睡眠。四个备选项中,首先排除[D]项。any 指“任何一个”,如:You can buy sugar at any big store.你可以在任何一家大商店里买到糖。余下的选项中,each指两个或多个中的每一个,例如:Each of them thinks different
