A lot of grown-ups worry that spending too much time playing video games isn’t good for a kid’s health. Now some doctors have noticed that kids who bring their hand-held game players to the hospital seem less worried about being there. These patients also seem to experience less pain when they are concentrating on a superhero adventure or a car race. At the Johns Hopkins Children’s Center in Maryland, young patients are finding hospital visits easier to deal with, thanks to a test program called the Hospital-based On-line Pediatric Environment (HOPE). Patients in HOPE have a life-threatening condition where their kidneys(肾脏)no longer filter(过滤)wastes from their blood. To get their blood cleaned, these kids must be hooked up to dialysis(透析) machines at the hospital three times a week, for at least three hours each time. HOPE allows kids to play online sports, racing, and adventure games with each other. Eventually they will be able to connect with kids in other hospitals who are suffering from the same problem. "We want to use the power of the Internet to bring together kids who feel that they are separated by their illness, and let them know that they are not alone," said Arun Mathews, the doctor who heads the program. He loves video games himself and got the idea to connect kids all over the country. Many researchers elsewhere are testing video game programs that might help young patients. For example, nine-year-old Ben Duskin of San Francisco, who was struggling with cancer helped to design a video game where players get rid of cancer cells. That’s all great news, because doctors already know that reducing pain and worry helps patients heal faster.

3.According to Arun Mathews, the main purpose of HOPE is to _________.

4.Which of the following plays the most important role in the HOPE project?

Nowadays the U.S. students are sleepy in school because they spend too much time texting, playing video games, watching TV and using the media in other ways.

“Heavy media use interferes with sleep by reducing sleep duration, making it harder to fall asleep, and lowering sleep quality,” Meilan Zhang, an assistant professor at the University of Texas at El Paso, wrote in her research review in the journal, Sleep Medicine.

But the relationship between youth’s media use and sleep is not so simple, said Michael Gradisar, who authored both that review and the Sleep Medicine meta-analysis. “Technology use is the new evidence when we are trying to answer ‘Why are school-age children sleeping less?’” said Mr. Gradisar, an associate professor of psychology at Flinders University in Adelaide, Australia.

There may be safe limits to technology use, Mr. Gradisar stated. For instance, recent research results indicate that using a bright screen for an hour before bed or even playing violent video games for less than that will not necessarily interfere with teenagers’ sleep, he wrote.

But longer periods of usage can be harmful to sleep, Mr. Gradisar added. Rather than delaying school start times, he said, the first step should be educating parents about limiting the hours that their children are using technology before bed, and enforcing a consistent bedtime.

Early school start times are also commonly blamed for students’ sleepiness, especially for adolescents. Secondary schools around the nation and the world have been delaying start times, often with positive results.

Mr. Minnich of the TIMSS and PIRLS International Study Center hesitated to put blame to any particular factor. But he did think that cost-saving measures to consolidate（合并）bus routes might help explain U.S. students’ sleepiness.

“For those children who board the bus first, they must get up earlier, may end up sleeping on the way to school, and may end up arriving at school sleepy.” he said.

1.Which of the following may be the best title for the text?

A. Kids benefit a lot from technology.

B. Several sleep troubles appear at school.

C. Some tips can help kids sleep well.

D. Several factors affect kids’ sleep.

2.Which of the following may be the good way to help kids sleep better?

A. Parents should be well educated.

B. Technology is forbidden at home.

C. Their playing time must be limited.

D. They are allowed to go to school early.

3.Who are most likely to be interested in the text?

A. The teachers.　　　　　　 B. The parents.

阅读下面短文，根据其内容写一篇60词左右的内容概要。

If you're worried that too much “screen time ”could badly influence your child's intelligence， new research suggests you might be right. By analyzing the data gathered from over 4，500U. S. kids aged 8 to 11 between 2016 and 2017，Jeremy Walsh，a postdoctoral fellow with the CHEO Research Institute in Ottawa， found that too much “screen time” could be harming your child's intelligence.

Kids with the sharpest intellects spent less than two hours a day on their cellophanes， tablets and computers coupled with 9 to 11 hours of sleep and at least an hour of physical activity. Too much screen time could be affecting kids ability to focus， especially if they are switching between apps on a device or between different screens at the same time， Walsh suggested. “ One leading theory is that much time on screens is spent multitasking using multiple apps or devices at once，” he said. “This can interfere with a child's ability to focus and keep interest on a task. It can be damaging the building blocks for good cognition(认知).”

Sleep is important for brain development， since that's when the brain reorganizes itself and grows， Walsh added. Besides， exercise has been shown to increase blood flow to the brain and oxygenation of brain tissues， and increases the connectivity of networks in the brain. Too much screen time could lead to a“ cascade”(瀑布) effect where kids don't get enough sleep and then are less active during the day.“ You can see how this would have an impact on brain health，” Walsh said.

What should parents do? Walsh advised setting firm rules about the use of screens including how long children are using the screens， the kinds of apps they are using and how many screens they are using at once. Concerned parents also should preview games or apps before letting their child play， seek out more interactive(交互的)options that engage the child's mind， and use parental controls to block or filter content and limit screen time.

Habits Of Highly Successful Students

Never Over-Study

When you spend too much time studying you will quickly lose focus and the time spent in studying will become ‘junk time’.

So what happens then?4.We all do it. We really shouldn't, though. So develop the habit of giving your primary energy to the hard tasks and completing the easy stuff last.

5.

Don't text your friends, don't chat while doing memory activities，don't make phone calls, just focus on what you're doing. Even if you focus on work' for 15 minutes followed by 5 mins of chatting, it’s better than 30 minutes of work while also chatting! You get that right?
