Question

Reducing the amount of sleep affects students’ performance at school. An American study asked schoolteachers to look at the effects of sleep restriction(限制） on children between six and twelve years of age. The teachers found that children who stayed up late had trouble thinking clearly and had more learning problems.

1. Doctor Fallone now works at the Forest Institute of Professional Psychology in Springfield, Missouri. He presented the results last month at a science reporter conference in Washington, D. C.. The publication Sleep also reported the findings.

The teachers were asked to complete weekly performance reports on seventy-four schoolchildren. The study lasted three weeks. During that period, Doctor Fallone and his team controlled the amount of sleep the children received.

2. During another week, every child was kept awake later than normal. Each night, the youngest boys and girls had less than eight hours of sleep. The older ones were limited to six and a half hours. During the final week of the study, each child received no less than ten hours of sleep a night.

The teachers were not told about how much sleep the students received. The study found that students who received eight hours or less had the most difficult remembering old information. 3.

The study did not find that sleep restriction caused hyperactivity(極度活躍) in the children. 4. .

Doctor Fallone said that the results provided experts and parents with a clear message: 5.

A. The sleeping time that the students have can be changed easily.

B. They also had trouble learning new information, completing difficult work and following directions.

C. During one week, the children went to bed and awoke at their usual time.

D. The teacher should restrict the amount of the sleep of the students.

E. Gahan Fallone did the study at the Brown Medical School and Bradley Hospital in the state of Rhode Island.

F. The teachers reported that students were, in fact, a little less active at school when they got less sleep.

G. When a child has learning problems, the issue of sleep must be considered among the possible causes.

【解析】

試題分析：研究表明減少學(xué)生睡眠時間會影響他們在學(xué)校的表現(xiàn)。

1.根據(jù)下文都是在介紹Fallone醫(yī)生現(xiàn)在的工作，得知前一句應(yīng)該是在講Fallone醫(yī)生以前的研究，因此選 E。

2.根據(jù)下一句“在另外的一周時間里”，得知前面在說“在一周期間孩子們的情況”，選C。

3.前面說孩子們睡眠不足影響記憶舊知識，接下來應(yīng)該說“記憶新知識方面等也有困難”，選B。

4.在睡眠限制的研究下，老師們說睡眠少導(dǎo)致孩子們在學(xué)校不活躍，選F。

5.最后Fallone醫(yī)生指出研究表明睡眠問題是導(dǎo)致孩子們出現(xiàn)學(xué)習(xí)問題的原因之一，選G。
