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(极度活跃) 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】

试题分析：研究表明减少学生睡眠时间会影响他们在学校的表现。

1.根据下文都是在介绍Fallone医生现在的工作，得知前一句应该是在讲Fallone医生以前的研究，因此选 E。

2.根据下一句“在另外的一周时间里”，得知前面在说“在一周期间孩子们的情况”，选C。

3.前面说孩子们睡眠不足影响记忆旧知识，接下来应该说“记忆新知识方面等也有困难”，选B。

4.在睡眠限制的研究下，老师们说睡眠少导致孩子们在学校不活跃，选F。

5.最后Fallone医生指出研究表明睡眠问题是导致孩子们出现学习问题的原因之一，选G。
