Question

    You may know about “junk food” like French fries. But do you know about “junk sleep”？

Recently, a British survey found that electronic(电子的) products in teenagers’ bedrooms are affecting(影响) their sleep.

The survey was done among 1，000 British kids from 12 to 16.It found that 30% of them got just 4 to 7 hours of sleep every day. But doctors say they need 8 to 9 hours.

Almost a quarter of the kids said they fell asleep more than once a week while watching TV, listening to music or using other electronic products.

“This is very worrying，” said Dr. Chris Idzikowski，a British expert，“We call it ‘junk sleep’．It means you don’t get enough sleep and the quality of the sleep is bad, too. If you don’t get a good rest，you don’t perform well in school the next day.”

The survey found that 40% of the kids felt tired each day，with girls between 13 and 16 feeling the worst. Nearly all the teenagers have a cellphone，an iPad or a TV in their bedrooms. And many of them have all the three.

【解析】

本文讲述了当今的青少年因为电子产品而影响了他们的睡眠，睡眠不够，就会影响他们第二天在学校的表现。

1.主旨大意题。根据第一段But do you know about “junk sleep”及下文介绍了什么影响了青少年的睡眠，可知，本文主要讲述的是“垃圾睡眠”。故选B。

2.推理判断题。根据第三段The survey was done among 1，000 British kids from 12 to 16.It found that 30% of them got just 4 to 7 hours of sleep every day，可知，在英国1000个孩子中调查，30%的孩子每天只睡4-7小时，也就是1000*30%=300，即300个孩子每天睡4-7小时。故选B。

3.细节理解题。根据We call it ‘junk sleep’．It means you don’t get enough sleep and the quality of the sleep is bad, too，可知， “垃圾睡眠”意思是你没有足够的睡眠，睡眠的质量也很差。根据常识，“垃圾食品”一般是指质量比较差，对身体有害的那些食品。由此可知，“垃圾食品”和“垃圾睡眠”有个相似之处，就是都质量低劣。故选A。

4.推理判断题。根据But doctors say they need 8 to 9 hours，可知，医生说青少年每天需要8-9个小时的睡眠，可知，A选项是错误的。根据Nearly all the teenagers have a cellphone，an iPad or a TV in their bedrooms，可知，几乎所有青少年在卧室里都有电话，平板电脑或电视，所以B选项是错误的。根据Almost a quarter of the kids said they fell asleep more than once a week while watching TV, listening to music or using other electronic products“几乎四分之一的孩子说，当他们在看电视，听音乐或用其他的电子产品时会不止一次睡着”，可知，青少年花费太多的时间在电子产品上，所以C选项是正确的。故选C。

5.推理判断题。根据Recently, a British survey found that electronic(电子的) products in teenagers’ bedrooms are affecting(影响) their sleep及Almost a quarter of the kids said they fell asleep more than once a week while watching TV, listening to music or using other electronic products，可知，青少年花费太多的时间在电子产品上，而直接会影响青少年的睡眠，不用任何电子产品在当今高科技的时代来说是不现实的，所以解决这个问题的最好方法就是减少青少年使用电子产品的时间，每天保证足够的睡眠。故选C。
