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

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 .

By now it's almost common knowledge that spending time in nature is good for you. Areas with more trees tend to be less polluted, so spending time there allows you to breathe easier. Spending time outdoors has been linked with reduced blood pressure and stress and seems to motivate people to exercise more.

“So it'll come as surprise that there's research showing that spending time in nature is good. There are dozens of papers showing that,” University of Exeter Medical School researcher Mathew P.White said.“We get this idea-patients are coning to us and they are asking, ‘Doctor, how long should I spend? ’And the doctor is saying,‘I don't really know.’”

So White and his team decided to find out by using data collected from nearly 20,000 people in England through the Monitor of Engagement with the Natural Environment Survey. And their answer? Two hours a week. People who spent at least that much time in nature either all at once or totaled over several shorter visits were more likely to report good heath and psychological well-being than those with no nature exposure.

Remarkably, the two-hour standard applied to men and women, to older and younger folks, to people from different ethnic backgrounds, occupational groups, socioeconomic levels, and so on. Even people with long-term illnesses or disabilities benefited from time spent in nature- as long as it was at least 120 minutes per week.

While the findings are based on a vast number of people, White cautions that it's rally just a correlation. Nobody knows why of how nature has this benefit, or even if the findings will stand up to more strict investigation.

“I want to be rally clear about this. This is in very early stages.We're not saying everybody has to do 120. This is really to start the conversation, saying, what would a threshold look like? What research do we need to take this to the next step before doctors can have the true confidence to work with their patients? But it's certainly a starting point.”

1.What does White want to figure out in the survey?

A.The benefits of being outside.

B.How long we should stay in nature.

C.The significance of outdoor activities.

D.Whether the British spend enough time in nature

2.What can we learn from the last two paragraphs?

A.The two-hour standard applies to everyone.

B.The reason why nature is beneficial is clear.

C.Further study is needed to confirm White's result.

D.The findings of White's survey have bee widely used.

3.What does underlined word“threshold”in the last paragraph mean?

A.Strict investigation. B.Following step.

C.Healthy lifestyle. D.Staring point.

4.What can be the best title for this text?

A.Nature and Health B.Two-hour Staying in Nature

C.Tips to Improve Health D.The Starting Point

By now it’s almost common knowledge that spending time in nature is good for you. Areas with more trees tend to be less polluted, so spending time there allows you to breathe easier. Spending time outdoors has been linked with reduced blood pressure and stress, and seems to motivate people to exercise more. So it’ll come as no surprise that there's research showing that spending time in nature is good, which has been known for thousands of years. There’s dozens of papers showing that.

University of Exeter Medical School researcher Mathew P. White said “We get this idea, patients are coming to us and they’re saying, ‘doctor, how long should I spend?’and the doctor is saying, I don’t really know.” So White and his team decided to find out by using data collected from nearly 20,000 people in England through the Monitor of Engagement with the Natural Environment Survey. And their answer? Two hours a week. People who spent at least that much time-either all at once or totaled over several shorter visits-were more likely to report good health and psychological well-being than those with no nature exposure. Remarkably, the researchers found that less than two hours offered no significant benefits.

So what’s so special about two hours? “ I have absolutely no idea. Really. We didn’t have an apriori（由因及果的）guess at what this would be. It emerged. And I’d be lying if I said we predicted this. I don’t know.” Even more noteworthy, the two-hour benchmark（基准）applied to men and women, to older and younger folks, to people from different ethnic backgrounds, occupational groups, socioeconomic levels and so on. Even people with long-term illnesses or disabilities benefited from time spent in nature—as long as it was at least 120 minutes per week.

While the findings are based on a tremendous number of people, nobody knows why or how nature has this benefit. “I want to be really clear about this. This is very early stages. We’re not saying everybody has to do 120. What research do we need to take this to the next step before doctors can have the true confidence to work with their patients? But it’ s certainly a starting point,” White said.

1.What is the first paragraph mainly about?

A.The benefits of spending time in nature.

B.The research of spending time in nature.

C.The characteristics of spending time in nature.

D.The common knowledge of spending time in nature.

2.What can we infer about the result of White and his team’s survey?

A.The time spent in nature should be 2 hours a week all at once.

B.2 hours a week at least in nature is beneficial to whomever you are.

C.The time spent in nature should be 2 hours a week, no more, no less.

D.2 hours a week in nature is too long for people with long-term illnesses.

3.What does White expect of the findings?

A.They will be in early stage.

B.They will be based on many people.

C.They will help all people go out in nature.

D.They will be improved and further research will be done.

4.Where is this text most likely from?

Three Modern Services

When you're working a full-time job, studying or on the hunt for work, life can feel exhausting. The good news is that modern technology has made life easier in many ways, and with the following services, you'll find you have more time and energy for the things that matter.

Meal kit delivery services

Meal kit delivery services are one of the most underestimated innovations of the 21st century. How they work is simple. At the beginning you choose how many people need to eat in your household. Then, what your dietary requirements are, and any other preferences. Finally, you get to choose which meal kits will be delivered to your door.

No matter your diet, you can have an appropriate meal kit delivered. For example, check out these low carb meal delivery options. The kit comes complete with all the ingredients you need, already prepared. All you have to do is to follow the simple recipe to put them together and pop your meal in the oven.

With meal kit delivery, you don’t have to worry about cooking or spending money on takeout. Your trips to the grocery store will become easier and you'll waste less money and food.

Taskrabbit

One of the most frustrating aspects of having a place you call your own is that you have to take care of the maintenance(维修). Even if you are renting, there are certain tasks that your landlord will expect you to see to, whether a leaky tap or a problematic electrical appliance.

For this, Taskrabbit connects you with freelancers who are willing to take on just about any task for you. You can hire someone to take care of your leaky tap rather than spending your own time and energy doing it. You're giving someone work while enjoying your time off.

Postmates

Finally, one of the most convenient and useful services is, of course, Postmates. With Postmates, you can get just about anything delivered or deliver something yourself. You can get someone to do your groceries for you – simply make a list of what you need and choose whether the shopper should call you if something is out or if they can decide on replacements themselves.

You can also use it for takeout, to send or receive documents, and any other delivery needs you have.

We live in an age of convenience, and we should take advantage of it. Start using the above services and you'll see your stress levels drop.
