A comprehensive study of 4，500 children conducted by the National Institutes of Health in 2018 shows that children who spent more than seven hours a day staring at screens showed evidence of premature thinning of their brain's cortex the outer layer that processes sensory information． "We don't know if it （1）　　（cause） by the screen time． We don't know yet if it's a bad thing． It won't be until we follow them over time （2）　　we will see if there are outcomes that are associated with the differences that we're seeing in this single snapshot，" Dr． Gaya Dowling． "What we can say is that this is（3）　　the brains look like of kids who spend a lot of time on screens． And it's not just one pattern．"

The problem isn't just screens （4）　　， but also the way screens tempt kids （and adults） away from something far more important： physical activity． More than 23 percent of adults and 80 percent of adolescents don't get enough physical activity， and according to a 2019 report from the World Health Organization （WHO）， these patterns of activity and rest arise （5）　　habits we develop early in life． "What we really need to do is （6）　　（bring） back play for children，" says Dr． Juana Willumsen， a WHO specialist in childhood obesity and physical activity， in a statement about new WHO guidelines issued in April 2019． "This is about making the shift from sedentary time to playtime， while （7）　　（protect） sleep．" Of course， children aren't completely to blame for their screen addiction．

Sometimes， the parents （8）　　complain about the role of screens in family life are just as guilty of spending too much time in front of one． A 2016 study （9）　　（conduct） by Common Sense Media found that parents spend up to nine hours a day in front of screens， mostly not for work﹣related reasons． While 78 percent of parents said they believed they were good screen time role models， the study found a disconnect between their behavior and their perception of their behavior． Parents need to limit screen time for themselves and especially for their kids（10）　　it means playing the bad guy． Our mental and physical health depends on it．

Section B
Directions: Read the following passage. Answer the questions according to the information given in the passage and required words limit.
Scientists have determined it's not advisable to hurry marriage. But what’s the best age to wed?
When Avril Lavigne announced she was splitting from her husband, comments from her friends suggested that she was only 21 when she tied the knot and later she said that she realized she'd been too young to make such a life-altering decision. Could fellow young celebrity divorcées(离婚者) Reese Witherspoon, Kate Hudson, and Britney Spears have also hit the same age-related issue?
The Magic Number
There are practical reasons for the mid-20s dividing line, and most of them boil down to two biggies: education and money.
It turns out that the more years of higher education a woman has under her belt on her wedding day, the lower the chances that she'll get divorced ... and by 25, you're more likely to have earned a degree or two. Educated women tend to be more confident about who they are and less willing to settle for a man who doesn't meet their standards.
Odds(可能性) are that by 25 you're also supporting yourself, so there's less incentive（刺激; 鼓励）for you to rush into marriage because you're seeking financial security from him. But the marriage-related benefits of working and having money of your own go beyond feeling secure. Learning to budget your cash carefully when you're single will help you avoid financial problems—one of the main causes of couple fights—for the rest of your life.
Knowing the Real You
At 25, you've had time for some crucial life experiences, including a relationship or two that may have improved your Mr. Right radar. You've probably dated enough to have a better idea of what you don't want in a man, which makes it easier to know what you can live with and can't live without.
Perhaps the most important aspect of waiting is that you'll know what your goals and values really are. While you don't want to marry someone just like you, marriage is a lot easier if you two share a similar outlook on life.
Twenty-four and already married to the man of your dreams? Don't worry: Many young marriages survive. But given the choice, you might consider putting off the big day until your mid-20s or later.

阅读表达
【1】If you are worried about things and are under a lot of stress at work or school, then you are probably not sleeping well. Worry can keep you awake, tossing and turning in bed until the early hours of the morning when you eventually fall asleep. When you wake up, you don’t feel refreshed, but tired and worn out and unable to face a new day.
【2】Dr Henry Winkle, in a recent newspaper article entitled Stress and Sleep, indicates that ____________. Dr Winkle says, “The more we worry, the less we sleep, the more we are unable to deal with stress. If we can find a way to get a good night’s sleep,” he adds, “we can often find the energy to deal with what’s worrying us.”
【3】So, what is a good night’s sleep? Research shows that the amount of sleep which people need in order to keep healthy varies a lot. Seven hours is about the average amount, though strangely enough, sleeping longer often gives you a headache instead of making you feel more refreshed.
【4】Dr Winkle believes that preparing for sleeping is important. People who work late should try to give themselves a short break and do something restful before going to bed. This could be watching TV or listening to music. Doing some exercise earlier in the day should help you to feel physically as well as mentally tired. A bedtime drink can also help, but coffee or tea should be avoided as they contain caffeine and will keep you awake. “When you put the light out, ” Dr Winkle says, “Concentrate on relaxing your muscles, working slowly up from your feet, and you’ll asleep before you know it.”
