(2016·淄博高三模拟)The longer a teenager spends using electronic devices such as

computers and smartphones，the worse their sleep will be，a study of nearly 10，

000 16­ to 19­year­olds suggests.

More than two hours of screen time after school was strongly linked to both delayed

and shorter sleep.Almost all the teens from Norway said they used the devices shortly

before going to bed.Many said they often got less than five hours sleep a night.

The teens were asked questions about their sleep routine on weekdays and at weekends，

as well as how much screen time they clocked up outside school hours.On average，

girls said they spent around five and a half hours a day watching TV or using computers，smartphones or other electronic devices.And boys spent slightly more time

in front of a screen—around six and a half hours a day，on average.Playing computer

games was more popular among the boys，whereas girls were more likely to spend their

time chatting online!

Any type of screen use during the day and in the hour before bedtime appeared to

disturb sleep—making it more difficult for teenagers to nod off．And the more hours

they spent on these devices，the more disturbed their sleep became.When daytime screen use totalled four or more hours，teens had a 49% greater risk of taking longer than an hour to fall asleep.These teens also tended to get less than five hours of sleep per night.

Dr.Hysing said her findings had suggestions for the wider population as so many people use these devices.“We know that sufficient sleep is essential for good physical and mental health.Logging off may be one important step toward securing a good night’s sleep.”

Prof Russell Foster，an expert at the University of Oxford，said，“This is an important study as it provides practical evidence that the use of electronic devices before bed does indeed reduce sleep duratio n.”He said teenagers should be warned of this. 【文章大意】本文是一篇说明文。一项研究发现，青少年花在电子设备上的时间越长，睡眠时间就越短，睡眠质量也越差。因为足够的睡眠对于身心健康有好处，所以青少年们在睡前应远离电子设备。

1．What is stressed in the first two paragraphs?

A．Teens now tend to have more problems with studies.

B．Teens get harder to fall asleep with more screen time.

C．Teens addicted to screen are likely to be more energetic.

D．Teens’ sleep duration has nothing to do with their screen time.

B解析：推理判断题。通读第一、二段可知，这两段在强调使用电子设备对青少年睡眠的影响。故选B项。其余选项和这两段内容无关。

2．By asking questions，the study finds ．

A．boys are more likely to chat online than girls

B．girls are more frequent on the screen than boys

C．teens are attracted by different electronic devices

D．teens use the screen for the same purpose

C解析：细节理解题。根据第三段第二、三句“On average，girls said they spent around five and a half hours a day watching TV or using computers，smartphones or other electronic devices.And boys spent slightly more time in front of a screen—around six and a half hours a day，on average.”可知，青少年使用的电子设备包括电视、电脑、智能手机等，C项正确。

3．What does the underlined phrase “nod off” in the fourth paragraph mean? A．Shut off. B．Get excited.

C．Focus on. D．Fall asleep.

D解析：词义猜测题。根据第四段第一句中“Any type of screen use during the day and in the hour before bedtime appeared to disturb sleep”可知，无论何种电子设备，在白天或睡前使用似乎都会打扰睡眠。由此可知，“making it more difficult for teenagers to nod off”意为“使用电子设备会让青少年更难睡着”。故D项与“nod off”意思接近，意为“睡着，打盹”。A项意为“停止，关掉”；B项意为“兴奋起来”；C项意为“集中注意力，关注”，都不符合题意。

4．How does Prof Russell Foster feel the study?

A．Beneficial. B．Uncaring.

C．Doubtful. D．Dissatisfied.

A解析：推理判断题。根据最后一段Prof Russell Foster所说内容中“T his is an
