Life for almost anyone is increasingly influenced by screens. Not only are screens themselves cheap to make, but they also make things cheaper. Any place that can fit a screen in can cut costs. And any activity that can happen on a screen becomes cheaper. The physical experience of learning, living and dying is becoming smooth glass. All of this has led to a curious new reality: Human contact is becoming a luxury good (奢侈品).
“What we are seeing now is the luxury of human engagement,” Milton Pedraza, the chief of the Luxury Institute, said. Expected spending on experiences such as enjoyable travel and dining is outpacing spending on goods, according to his company’s research, and he sees it as a direct response to the rapid increase of screens.
Screens exposure starts young. And children who spent more than two hours a day looking at a screen got lower scores on thinking and language tests, according to early results of a landmark study supported by the National Institutes of Health. The study focuses on brain development of more than 11,000 children. Most disturbingly, the study is finding that the brains of children who spend much time on screens are different. For some kids, their cerebral cortex (大脑皮层) would become thinner before expected time. In adults, one study found an association between screen time and depression.
There is also the reality that in our culture of increasing separation, in which so many of the traditional gathering places and social structures have disappeared, screens are filling a vital gap.
For normal people, running away from the screen becomes impossible. It’s not a luxury, and it’s easy to get. It is normal for more people to need the network constantly. In addition, it has become an important part of social interaction.
1.What can we infer from Paragraph 1?
A.Screens make everything in life cheaper.
B.People’s life is totally controlled by screens.
C.It is difficult for people to contact each other.
D.Face-to-face communication is decreasing nowadays.
2.According to the text, which of the following WON’T be caused by long screen time?
A.More social interaction. B.Depressive state of mind. C.Different brain structures. D.Poorer academic performance.
3.What is the author’s attitude towards the popularization of screen?
A.Favorable. B.Skeptical. C.Concerned. D.Opposed .

For many adolescents, “screen time” is almost a full-time job that could lead to obesity, diabetes and other health issues, a Canadian researcher says.
Adolescents now spend an average of six hours a day in front of some type of screen, whether it’s a television or computer screen or one of the many portable devices now popular with young people, studies done by Dr. Ian Michael Janssen show. “They spend more hours daily in front of a screen than they do in a classroom in a given year,” said Janssen, a researcher at Queen’s University in Kingston, Canada. The result is a rise in obesity rates among adolescents. Unfortunately, fixing the problem isn’t as easy as simply cutting down screen time, Janssen cautions. “Decreasing screen time will not automatically increase physical activity levels,” said Janssen, Some active kids also spend a lot of time in front of television and computer screens, and some kids who have low screen times also have low levels of physical activity, he points out.
As well, screen time is not necessarily bad, Janssen said. “The tricky part is that children today need to be using computers,” he said. Computers are required for schoolwork, and technological skills are important for future job prospects. The quality of screen time matters too, along with the quantity---consider the negative health messages found in food advertising during children’s shows, he said. Ideally, children should aim for no more than two hours of recreational screen time a day.
Janssen’s real worry about the rise in childhood obesity rates is not that there are now rare cases of type 2 diabetes in kids, where once there were none, hut the health problems these children are likely to face in the future as adults, including high blood pressure, high cholesterol and cardiovascular disease.
1.Which one doesn’t belong to “screen time” according to the passage?
A. Watching TV. B. Surfing the Internet.
C. Seeing a film on an MP4. D. Making a telephone call.
2.In Janssen’s opinion, kids had better to keep healthy.
A. lose weight. B. decrease screen time
C. take physical activities D. go on a diet
3.What’s the researcher’s attitude towards “screen time of adolescents" ?
A. Concerned. B. Passive.
C. Positive. D. Frightened.
4.We can learn from the passage that .
A. many of the people having full-time jobs suffer from obesity and diabetes.[
B. decreasing screen time can’t really solve the problem
C. children today most use computers to finish their school work
D. a new type of obesity in kids becomes Janssen’s real worry

Screen time increases by 300 percent between the ages of 1 and 3 according to a recent study. In a perfect world, parents would always choose outdoor time over screen time. But for many parents, decreasing screen time isn't as simple as it sounds. That's because screens are increasingly used as an entertainment and distraction(分心)tool for kids which parents think is necessary due to a lack of quality childcare.
The United States government defines affordable childcare as care costing no more than 7 percent of a family's total income, yet more than 40 percent of families say they set aside more than 15 percent of their total income for it, according to a 2019 survey published by Care. com.
Affordable childcare in America is a dream. “Screen time is used as a last substitute for childcare for many families,” says licensed child therapist(治疗师)Katie Lear. “Particularly for parents who work from home, it can be hard to justify hiring a caregiver or paying for daycare. And yet children need to be able to keep themselves occupied during important work calls. Turning on the TV can buy the parent some valuable time during what can be a very tiring day."
If affordable childcare wasn't just a daydream, if the system we have wasn't dependent on two incomes, if parents could actually afford not to work 50+ hours a week, if childcare centers could afford to pay their workers a desirable wage, then maybe, we'd see screen time decrease instead of increase. We know our kids should be interacting with something other than You Tube videos and flash games for hours a week. But before we fix our broken system and before affordable, quality childcare becomes a reality, parents and caregivers are going to do whatever they can to make it, and that includes using screens as passive childcare.
1.Why do parents allow their children to spend much time on screens?
A.To please their children.
B.To make up the lack of quality childcare.
C.To attract kids' attention to classes online.
D.To help children learn about necessary technology.
2.What do the statistics in Paragraph 2 indicate?
A.Childcare workers have high income.
B.Childcare centers are popular in America.
C.Childcare is a heavy burden for parents.
D.Childcare is supported by local government.
3.Why is Lear mentioned in the text?
A.To uncover the reason for screen time as childcare.
B.To prove the advantages of adopting c-products.
C.To present the ways of parents' improving childcare.
D.To explain the benefits of hiring a caregiver.
4.What's the key in reducing children's screen time?
A.Enough company time. B.High income in the family.
C.Turning off the TV. D.Hiring a caregiver.

It is becoming increasingly important for researchers to closely monitor our ocean life. However, observing sea creatures up close is almost impossible since human presence scares them. Now, thanks to the The Soft Robotic Fish, also known as SoFi, researchers may be able to keep a close eye on the sea creatures.
Built by MIT Computer Science and Artificial Intelligence Laboratory (CSAIL), the white remote-controlled robot resembles the real fish, complete with a tail that waves from side to side. Though not the first autonomous underwater vehicle (AUV) created to monitor the ocean, SoFi settles many of the problems that have blocked the usefulness of previous robot fish.
Previous AUVs have had to be linked to boats because of radio frequency communications don’t work well underwater. To overcome the problem, Director of the CSAIL Daniela Rus and her team used sound waves. The technology can travel greater distances allowing divers to pilot SoFi from up to 50 feet away.
Also limiting the usefulness of traditional AUVs is the risk of collision. With the outside made of soft silicone (硅树脂) rubber and flexible plastic that keeps its inbuilt electronics dry, SoFi poses no such danger. “Collision avoidance often leads to unnecessary movement, since the robot has to settle for a collision-free path,” says Rus. “ In contrast, a soft robot is not only more likely to survive a collision but also could use it as information to form a more workable movement plan next time around.”
During test dives, SoFi moved alongside the ocean life at depths of 50 feet for up to 40 minutes at a time, taking photos and making videos. The researchers say sometimes the fish would swim alongside the strange-looking robot-fish out of curiosity, while at other times they took no notice of its existence.
While SoFi presently only records video, future versions will include sensors. The researchers also hope to make it more autonomous. “We imagine someday it might help us uncovers more secrets from the amazing underwater world that we know so little about,” says Rus.
1.What can we learn about SoFi?
A. Its tail is flexible. B. It is the first AUV.
C. It is closely controlled. D. Its presence scares sea animals.
2.What can be learned from paragraph 3?
A. Sound waves travel faster than radio.
B. Radio does not work well underwater.
C. Previous AUVs use radio to communicate.
D. A boat travels along with SoFi on the water.
3.How does SoFi differ from traditional AUVs?
A. It is controlled above.
B. It can avoid a collision.
C. It can smartly adjust its movement plan.
D. It is set for a collision-free path.
4.Where is the passage possibly taken from?
A. A news report. B. A science fiction.
C. A social website. D. A short biography.
