Question

According to a recent survey, British teenagers are not in good health because they don’t have enough time for sleep. They don’t sleep well, either. They are often disturbed(打扰) by electronic gadgets(器具，装置) in their bedrooms. We call such kind of sleep “junk sleep”.

We did a survey among 1,000 students aged 12 to 16, and we found out that 30 percent of them slept for only 4 to 7 hours a day. Nearly a quarter said they fell asleep while they were watching TV, listening to music or using other electronic gadgets.’

Nowadays, almost all the teenagers have a phone, music system or TV in his or her bedroom. Almost 20 percent of the teenager boys said the quality of their sleep were not good. It was affected by leaving their TVs or computers on. The survey also found out that 40 percent of young people felt tired every day. What’s more, the girls aged 15 to 16 felt the worst among them.

“Teenagers need to realize the importance of sleeping well. If they sleep well, they will be able to study hard and perform well at school. I am shocked to know that so few teenagers have noticed the close connection between sleep and schoolwork,” said Dr Chris.

【解析】根据一项调查，英国的青少年睡眠质量很差，他们是由于受到了卧室里电子设备的影响，专家希望他们能够意识到好的睡眠和成绩是有很大联系的，要消除这样不好的影响。

1.细节理解题。根据短文的第一段中According to a recent survey, British teenagers are not in good health because they don’t have enough time for sleep. They don’t sleep well, either. They are often disturbed(打扰) by electronic gadgets(器具，装置) in their bedrooms可知，英国的青少年们睡眠质量非常差，因为他们受到了电子设备的打扰。由此可知应选B。

2.细节理解题。根据短文第二段中We did a survey among 1,000 students aged 12 to 16, and we found out that 30 percent of them slept for only 4 to 7 hours a day可知，这个调查的结果显示，有大约30%的学生一天睡眠的时间是4到7个小时。由此可知选C。

3.词义猜测题。根据文意以及这个单词所在的句子Almost 20 percent of the teenager boys said the quality of their sleep were not good可知，文章讲述的是英国的青少年们受到了电子设备的影响，睡眠很差。这个单词和sleep组成了一个名词短语，不可能是睡眠的数量不好，或者是睡眠的时间不好，应该是睡眠的质量差。故应选B。

4.主旨大意题。短文的第一段是文章的中心段落，在这一段中作者提出了这篇短文的主要话题，根据British teenagers are not in good health because they don’t have enough time for sleep. They don’t sleep well, either. They are often disturbed(打扰) by electronic gadgets(器具，装置) in their bedrooms. We call such kind of sleep “junk sleep”可知，由于受到电子设备的影响，很多英国的青少年睡眠质量很差，我们就把这种睡眠叫做“垃圾睡眠”，下文具体讲述了这个调查的结果和影响，因此B选项这个词是文章的关键词，故选B。

点睛：这篇短文讲述了一个调查的结果，短文中心突出，中心句就在第一段中，因此读懂了第一段我们就把握住了文章的主题。后面的题目设置有细节理解、词义猜测和主旨大意。主旨大意题要求我们概括文章的中心，正确答案必须有概括性、全面性、精确性的特点，不能以偏概全，更不能是与文章无关的表达。第4小题要求我们概括这篇短文的主旨，通过阅读整篇文章可知，这篇短文是总分的结构，在短文的第一段中就提出了文章的主题，即英国青少年睡眠质量差这个问题，因此junk sleep就是这篇短文所要谈论的话题，故应选B。
