Limiting kids' recreational(消遣) screen time to less than two hours a day, along with enough sleep and physical activity, is associated with improved cognition(认知), according to a study published in The Lancet Child & Adolescent Health.

The study included about 4,500 US children aged 8 to 11 and measured their habits against the Canadian 24-Hour Movement Guidelines for Children and Youth. It found that 51% of the children got the recommended(建议) nine to eleven hours of uninterrupted sleep per night, 37% met the recreational screen time limit of two hours or less per day, while 18% met the physical activity recommendation of at least 60 minutes of accumulated physical activity a day. Only 5% of the children in the study met all three recommendations; 30% met none at all.

The researchers found that as each recommendation was met by a participant, there was a positive association with global cognition, which includes memory, attention, processing speed and language. Those who met all three had the most "superior" global cognition, followed by those meeting the sleep and screen time recommendation and finally the screen time recommendation alone, according to the study.

Other organizations, such as the American Academy of Pediatrics have guidelines in place to help with the management of children's screen time. The organization suggests putting realistic rules or limits in place for how long your children are on their screens, knowing who they are talking to and what they are doing. The amount of recommended screen time depends on the age of the child. Besides, parents should also make sure to encourage physical activity and have bedroom rules such as creating "tech-free zones".

1.Who are the target readers of this passage?

A. Researchers.　　 B. Teachers.

C. Parents.　　 D. Children.

2.What is the main idea of this passage?

A. A study on children’s screen time is published.

B. US children fail to meet movement guidelines.

C. Organizations are concerned about children’s cognition.

D. Limitation on children's screen time is linked to better cognition.

3.According to the passage, which of the following might contributes least to cognition?

A. Screen time limit.　　 B. Sleep hours.

C. Physical activity time.　　 D. Sleep hours and screen time limit.

4.Why does the American organization suggest creating "tech-free zones”?

A. To make sure children have enough physical playtime.

B. To make sure children have enough sleep time.

C. To make sure children have recreational time.

D. To protect children against radiation.

We walk, talk and sleep with our phones. But are we more — or less-connected? Just as remarkable as the power of mobility, over everything from love to global development, is how fast it all happened. It is hard to think of any tool, any instrument, any object in history with which so many developed so close a relationship so quickly as we have with our phones. Not the knife or match, the pen or page. Only money comes close—always at hand, don't leave home without it. But most of us don't take a wallet to bed with us. don't reach for it and check it every few minutes, and however useful money is in pursuit of fame, romance, revolution, it is inert compared with a smart phone — which can replace your wallet now anyway.

So how do we feel about this? To better understand attitudes about mass mobility, Time, in cooperation with Qualcomm, started the Time Mobility Poll, a survey of close to 5,000 people of all age groups and income levels in eight countries. Even the best survey can be only a snapshot in time, but this is revealing a lot about both where we are now and where the mobile wave is taking us next.

Not for a day — in most cases not even for an hour. In Time's Poll, 1 in 4 people check it every 30 minutes, 1 in 5 every 10 minutes. A third of respondents admitted that being without their mobile for even short periods leaves them feeling anxious. It is a form of sustenance, that constant feed of news and notes and nonsense, to be the point that twice as many people would pick their phones over their lunch if forced to choose. Three-quarters of 25-to 29-year-olds sleep with their phones.

Americans are grateful for the connection and convenience their phones provide, helping them search for a lower price, navigate a strange city, expand a customer base or track their health and finances, their family and friends. But in some ways Americans are still ambivalent （矛盾的）; more than 9 in 10 Brazilians and Indians agreed that being constantly connected is mostly a good thing. America's 76% was actually the lowest score.

1.What can have a comparison with phones?

A.A pen. B.A knife.

C.A match. D.Money.

2.It can be inferred that a smart phone can also have the function of ______

A.paying bills. B.helping sleep.

C.pursuit money. D.cutting things.

3.Why did Time start the Time Mobility Poll?

A.Because it wanted to cooperate with Qualcomm.

B.Because it wanted to know where the mobile wave was taking us.

C.Because it wanted to learn people's attitudes to mass mobility

D.Because it wanted to know how well the mobile wave went.

4.What does Paragraph 3 mainly tell us?

A.Mobile phones have become a tool to sleep with.

B.Mobile phones have become a way to get news.

C.Mobile phones have become a tool to order food.

D.Mobile phones have become a must in daily life.

5.According to the passage. Americans are less ______.

A.likely to show appreciation to their phones.

B.constantly connected than Indians.

C.likely to search for a lower price.

D.likely to find ways in a strange city.

Parents may worry that their children aren’t getting enough quality sleep. However, now there’s a smart bed to provide adults with sleep data by a smart app. The SleepIQ bed can alert (发出报警声) parents when their children are asleep, as well as if they are risking out of bed. If a child is tossing and turning (辗转反侧), it can also be adjusted to make it more comfortable.

The bed was first introduced at the International Consumer, Electronics Show (CES). It claims to be the only one in the world, which adjusts with children as they grow. Children don’t need to wear a smart-band or alternative wearable device in bed. Instead, the quality of their sleep is measured by sensors(传感器) in the bed, which monitor (监测) their present, average breathing rate, heart rate and movement. Then it assesses (评定) quality of sleep. They are given a SleepIQ score for each night’s sleep. Using an accompanying app, parents can see it clearly. It also allows parents to monitor routines (常规) that affect sleep, such as exercise, caffeine and screen time, helping them to develop a routine that helps develop a good night’s shut-eye.

The bed sends an alert to the app when it detects (探测) a child is out of bed or is restless, such as if he is having a nightmare. Its firmness can be adjusted to change the level of comfort and support to suit children as they grow. A “head tilt (倾斜)” feature for reading is built in, and parents can remotely turn a light out after reading time using the app. There are also fun features such as a “monster scanner”, which uses a mobile phone to check for and fight monsters under the bed. What’s more, an automatic light will guide children, if they need to get up in the middle of the night.

The bed is available online and at Sleep Number stores in the US from around $499, almost the same as the beds we are sleeping on.

1.What does the text mainly talk about?

A.The smart bed helping sleep better.

B.Risks that children face when sleeping.

C.How parents take care of children.

D.How to get a good sleep.

2.If children sleep on the SleepIQ bed, ________.

A.their sports performance will be improved

B.they no longer need to get up in the middle of the night

C.their health condition will be improved greatly

D.their sleep quality will be improved

3.We can know from the text that ________.

A.the smart bed is as cheap as an ordinary one

B.another smart bed is needed with children growing older

C.children will never fall out of the SleepIQ bed

D.the SleepIQ bed is the best bed around the world

4.Having the SleepIQ bed, ________.

A.children won’t have a nightmare

B.parents can be free from some worries

C.parents don’t need to care for children any more at night

D.children had better not read on the bed

About half American teenagers do not get enough sleep on school nights.They get an average of sixty to ninety minutes less than experts say they need.

One reason for this is biology.Experts say teens are biologically programmed to go to sleep later and wake up later than other age groups.Yet many schools start classes as early as seven in the morning.As a result，many students go to class feeling like sixteenyearold Danny.He is an active teen— except in the morning.“Getting up in the morning is pretty terrible.I’m just very out of it and tired.Through the first and second period I can hardly stay awake,” he said.

Michael Breus is a psychologist.Teens，he says，need to sleep eight to nine hours or even nine to ten hours a night.He says sleepy teens can experience a form of depression(消沉) that could have big influence on their general well being.It can affect not just their ability in the classroom but also on the sports field and on the road.So what can schools do about sleepy students？The psychologist says one thing they can do is to start classes later in the morning.Studies show that students can improve by a full letter grade in their first and second period classes.

Eric Peterson is the head of St.George’s School in the northeastern state of Rhode Island.He wanted to see if a thirtyminute delay(推迟)would make a difference.It did.He says visits to the health center by tired students decreased by half.Late arrivals to the first period fell by a third.And students reported that they were less sleepy during the day.Eric Peterson knows that changing start times is easier at a small school like his.But he is hopeful that other schools will find a way.

1.What’s the best title for the passage?

A．Later classes，fewer sleepy teens

D．Fewer classes，more happiness

2.The underlined word“this”in the second paragraph refers to________.

3.Michael Breus thinks that________.

B．it’s not easy for Eric Peterson to change start times

C．students in St.George’s School can get up later than before

D．students in St.George’s School aren’t late for school any more

High school dropouts(辍学者)earn an average of ＄9000 less per year than graduates．Now a new study dispels a common belief why they quit．It’s much more basic than flunking out(不及格)．

Society tends to think of high school dropouts as kids who just can’t cut it．They are lazy, and perhaps not too bright．So researchers were surprised when they asked more than 450 kids who quit school about why they left．

“The vast majority actually had passing grades and they were confident that they could have graduated from high school, ” John Bridgeland, the executive researcher said．About 1 million teens leave school each year．Only about half of African-American and Hispanic(美籍西班牙的)student will receive a diploma(证书), and actually all dropouts come to regret their decision．So, if failing grades don’t explain why these kids quit, what does?Again, John Bridgeland：“The most dependable finding was that they were bored．”“They found classes uninteresting; they weren’t inspired or motivated．They didn’t see any direct connection between what they were learning in the classroom to their own lives, or to their career aspirations．”

The study found that most teens who do drop out wait until they turn sixteen, which happens to be the age at which most states allow students to quit．In the US, only one state, New Mexico, has a law requiring teenagers to stay in high school until they graduate．Only four states：California, Tennessee, Texas and Utah, plus the District of Columbia, require school ?attendance? until age 18, no exceptions, another researcher, says raising the compulsory(义务的)attendance age may be one way to keep more kids in school．

“As these dropouts look black, they realize they’ve made a mistake．And anything that sort of gives these people an extra push to stick it out and it through to the end, is probably helpful measure．”

New Hampshire may be the next state to raise its school attendance age to 18．But critics say that forcing the students unwilling to continue their studies to stay in school misses the point－the need for reform．It’s been called for to reinvent(彻底改造)high school education to make it more challenging and relevant(中肯的, 切题的), and to ensure that kids who do stick it out receive a diploma that actually means something．

1.Most high school students drop out of school because ________．

A．they have failing grades

B．they take no interest in classes

C．they are discriminated against

D．they are lazy and not intelligent

2.According to the passage, which state has a law requiring school attendance until they graduate?

A．New Hampshire．

B．Utah．

C．New Mexico．

D．The District of Columbia．

3.The underlined words “stick it out” probably mean “________”．

A．complete schooling

B．solve the problem

C．love having classes

D．believe in themselves

4.In the last paragraph, the writer is trying to ________

A．analyze the reason why students quit school

B．suggest raising the compulsory attendance age

C．call on to reform　 high school education

D．wish to make laws to guarantee no education
