Question

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

Recently, a British survey found that electronic(電子的) products in teenagers’ bedrooms are affecting(影響) 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.

Answer 1

【答案】

【1】B

【2】B

【3】A

【4】C

【5】C

【解析】

本文講述了當(dāng)今的青少年因為電子產(chǎn)品而影響了他們的睡眠，睡眠不夠，就會影響他們第二天在學(xué)校的表現(xiàn)。

【1】主旨大意題。根據(jù)第一段But do you know about “junk sleep”及下文介紹了什么影響了青少年的睡眠，可知，本文主要講述的是“垃圾睡眠”。故選B。

【2】推理判斷題。根據(jù)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，在英國1000個孩子中調(diào)查，30%的孩子每天只睡4-7小時，也就是1000*30%=300，即300個孩子每天睡4-7小時。故選B。

【3】細節(jié)理解題。根據(jù)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”意思是你沒有足夠的睡眠，睡眠的質(zhì)量也很差。根據(jù)常識，“垃圾食品”一般是指質(zhì)量比較差，對身體有害的那些食品。由此可知，“垃圾食品”和“垃圾睡眠”有個相似之處，就是都質(zhì)量低劣。故選A。

【4】推理判斷題。根據(jù)But doctors say they need 8 to 9 hours，可知，醫(yī)生說青少年每天需要8-9個小時的睡眠，可知，A選項是錯誤的。根據(jù)Nearly all the teenagers have a cellphone，an iPad or a TV in their bedrooms，可知，幾乎所有青少年在臥室里都有電話，平板電腦或電視，所以B選項是錯誤的。根據(jù)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“幾乎四分之一的孩子說，當(dāng)他們在看電視，聽音樂或用其他的電子產(chǎn)品時會不止一次睡著”，可知，青少年花費太多的時間在電子產(chǎn)品上，所以C選項是正確的。故選C。

【5】推理判斷題。根據(jù)Recently, a British survey found that electronic(電子的) products in teenagers’ bedrooms are affecting(影響) 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，青少年花費太多的時間在電子產(chǎn)品上，而直接會影響青少年的睡眠，不用任何電子產(chǎn)品在當(dāng)今高科技的時代來說是不現(xiàn)實的，所以解決這個問題的最好方法就是減少青少年使用電子產(chǎn)品的時間，每天保證足夠的睡眠。故選C。
