【题目】 Parents who fear their kids are spending too much time in front of screens now have more reasons for concern.

New research funded by the National Institutes of Health found brain changes among kids using screens more than seven hours a day and lower cognitive(认知的) skills among those using screens more than two hours a day.

When studies find links between screen time and negative outcomes, some have argued that this is just the latest moral panic over technology.After all, didn't today's grandparents once worry that their kids were watching too much TV or talking on the phone too much? Those kids( today's parents )turned out OK, right?

In a new paper, my co-authors and I found that children who spent four or more hours a day on portable devices(设备)--compared with no time-were over 44 percent more likely to sleep not enough.TV time was also connected to less sleep, but not as strongly or consistently.

For one thing, TV is not so psychologically stimulating(刺激性的)as a portable device like a smartphone, which, unlike TV.doesn’t exist to simply consume media.Smartphones have also become a huge part of social life, whether it's texting with friends or interacting with them on social media.

And unlike TV, portable devices can be silently carried into the bedroom or even the bed, resulting in some teens using them throughout the night.

That might explain why lack of sleep among teens spiked after 2012-just as smartphone use became common.

So what is a parent-or anyone who wants to sleep well-to do?

First, it's best for smartphones and tablets to stay out of the bedroom after"lights-out"time.Nor is it a great idea to use the devices within an hour of bedtime, as their blue light influences the brain’s ability to produce melatonin (褪黑激素).Finally, as a general rule, two hours a day or less spent on portable devices is a good guideline.These rules apply to parents, too -not only kids.

1What is the third paragraph mainly about?

A.Today's parents' health condition.

B.Grandparents’ influence on their kids.

C.Bad effects of too much screen time on kids.

D.Some people,'s opinion on the findings of the studies.

2What is a reason for portable devices' being more strongly associated with less sleep?

A.They only consume media.B.They are convenient to carry.

C.They are better used in daytime.D.They are independent of social life.

3What does the underlined word"spiked" in paragraph 7 probably mean?

A.rose quickly.B.stood still.

C.grew equally.D.decreased abruptly.

4What's the author's advice on how to get a good sleep?

A.Never bring screens into the bedroom.

B.Allow parents to adapt the rules for themselves.

C.Avoid the devices within an hour of bedtime.

D.Spend exactly two hours a day on the devices.
