Teenagers who spend more time watching TV, using iPads and playing electronic games take longer to fall asleep and get poorer quality rest. A new study suggests the growth in use of electronic media devices by children could harm their physical and mental health.
The 16-19-year-olds were asked how much screen time they spent outside school hours, and on what activities, for any of six electronic devices: computer, tablet, smartphone, MP3 player, games console（游戏机）and TV. They were also asked questions about their sleep routine on weekdays and at weekends: when they normally went to bed and got up; how much sleep they needed to feel rested; and how long it took them to get to sleep. Girls spent longer on their computers chatting online while boys spent longer playing games on computers.
The study found poorer quality sleep was related to more time spent on such devices, and it often took more than an hour to drop off. Total daytime screen use of more than four hours was related to a 49 percent greater risk of taking longer than 60 minutes to fall asleep.
On average, the teens said they needed 8-9 hours of sleep to feel rested. But those who spent more than two hours emailing or chatting online were more than three times as likely to sleep for less than five hours. Those spending more than four hours in front of any screen were 3.5 times as likely to sleep for less than five hours. Computers were the device most likely to cause problems.
Dr Mari Hysing, of Uni Research Health, Bergen, said screen use may simply replace sleeping time or it may affect sleep by stimulating the nervous system. It is also possible that the light from electronic devices may affect a teenager’s body clock. “The recommendation is not to have a TV in the bedroom,” added Dr Mari Hysing.
1.What do boys prefer to do on the Internet?
A.They prefer to watch TV on computers.
B.They prefer to get solutions for homework.
C.They prefer to make friends with others.
D.They prefer to spend time on computer games.
2.The underlined phrase “drop off” in the third paragraph may mean “________”.
A.get up B.pay for
C.take over D.fall asleep
3.What will happen if children spend over two hours online?
A.They will suffer from lack of sleep.
B.They will sleep for over eight hours.
C.They will feel excited during daytime.
D.They will create a new body clock.
4.What does Dr Mari Hysing advise people to do?
A.change the children’s sleeping time
B.find ways to stimulate nervous system
C.make children sleep as they could
D.remove electronic devices from children’s bedroom

Children and teenagers who spend lots of time in front of screens---especially TVs---
are easier to get more weight as they grow, according to a new study.The findings agree with the research suggesting all that inactive sitting and always watching advertisements may lead to poor eating habits.
Researchers used results from a long-term study of children who took part in the surveys every two years. Children were between ages 9 and 16 when the study started. Out of 4,300 girls in the study, 17 percent were overweight or obese（肥胖的）. Twenty-four percent of the 3,500 boys were also above a healthy weight.
The surveys included questions about their height and weight as well as how much time they spent watching TV and DVDs and play
ing computer and video games.From one survey to the next, each one-hour increase in children’s daily TV watching was in connection with an increase of about 0.1 points on a body mass index (BMI)（体质指数）, which measures weight in connection with height. There’s an increase of about
half a pound in weight per extra hour of TV.“The weight of the evidence is so strong that television watching is connected with unhealthy changes in weight among youth,” says Jennifer Falbe, who led the study while at the Harvard School of Public Health in Boston.
“It's important for parents to know that all the obesity-causing（引起肥胖的）screens really should be limited in their children's lives.” Falbe says. “When children watch TV, there are many food advertisements on TV that might lead them to eat a cookie or drink a soft drink.” What's more, she says, “they can get into a hibernating(冬眠) state on the sofa, even if children are sitting down while playing a computer game.”
1.Which of the following statements can be the best title for the text?
A. A new study on screens.
B. TVs do harm to children.

D. Too much screen time leads to obesity.
2. How many children took part in the study?

fatter.

C. 0.3 D. 0.7
4.According to Falbe , what should parents do to stop children getting fat?
A. Limiting the time of children watching TV.
B. Buying children food advertised on TV.
C. Not allowing children to watch TV.
D. Encouraging children to play computer games.

In modem times, many teenagers have idols of their own who are always some stars on TV on the Internet, etc. These stars always think that a slimmer figure may be perfect for themselves. However, does size really matter? Are teenage fans trying hard to become like their idols? Do famous stars really have the power to influence people especially teenagers?
For the longest time, many parents blame (责备) teen idols for influencing the way their kids act. Have you noticed how teens idolize the stars these days?

But teenagers are easily influenced because teenage years are the period when our personality and identity developments take place. Teens watching TV shows and reading magazines are easily pulled into the dieting and harmful eating habits because the media have some ways to pull these acts. They use thin models and stars to endorse (宣传) products or to star in an up-and-coming shows or movies. With fierce competition, stars are forced to eat less and do extreme exercise routines to get the roles or offers that come their way.
Living in today’s time and generation is a bit disturbing to a lot of parents. Media, especially as well as the stars, have a very powerful influence to drive teenagers to good or bad.

The bed should be used as a place for sleep, but more and more people like to read an iPad a lot in bed before they go to sleep.
Charles Czeisler, a professor at Harvard Medical School, and his coworkers got a small group of people for an experiment. For five days in a row, these people read either a paper book or an iPad for four hours before sleep. Their sleep patterns were monitored all night. Before and after each trial period, they took hourly blood tests to paint a day-long picture of just how much melatonin(褪黑激素) was in their blood at any time.
When the people read the iPad as compared to the paper books, they felt less sleepy at night and less active the following morning. People also took longer to fall asleep on the iPad nights, and the blood tests showed that their melatonin secretion(分泌) was delayed by an hour and a half.
The researchers concluded that because of the rise of e-readers and the widespread use of e-things among children and teenagers, more research into the "long-term influence of these e-things on health and safety is urgently needed." Czeisler and coworkers went on, in the research paper, to point out that reading an iPad in bed may increase cancer risk.
However, software has been developed that can reduce some of the blue light from the screens of phones and computers, and there are also glasses that are made to reduce short wavelengths. While they seem like a logic solution for the nighttime tech users, it needs more research.
1.In Charles Czeisler's experiment, the group of people were asked to_______.
A.sit in a row and receive the strict tests
B.have their sleep patterns observed all night
C.read a paper book and an iPad before sleep
D.have their blood tested per hour during the trial
2.The third paragraph tells us the iPad readers were likely to_______.

3.The special software recently developed can _______.
A.reduce the blue light from the screens completely
B.help prevent eyes being harmed by short wavelengths
C.reduce the harm caused by doing nighttime e-reading
D.be used in all the e-things widely and safely
4.Which of the following can be the best title for the text?
A.No e-reading in bed before sleep
B.New software for night e-readers
C.Wrong things to do before bedtime

Children who spend more time reading with their parents have a greater chance of becoming better readers than those who don’t. With help from their parents, children can learn techniques(技巧) to improve their reading skills.
“A lot of parents think after their child learns to read, they should stop reading to them,” Donna George said. “They are sadly mistaken.”
George offers her services to parents at the Title I Learning Centers. She said reading aloud to children may be the most valuable(有价值的) thing parents can do. “It is better for children to hear things at a higher level than where they are,” George said. “Parents are their child’s first teacher.” Parents help their children build listening, phonics(拼读法), comprehension(阅读理解) and vocabulary skills when they read aloud to them.
Before parents can identify reading problems, they should escape the enemy----television and limit the time their children spend watching television. George suggested not allowing kids to have a TV in their bedrooms, setting a schedule of when kids can watch or keeping a list of how many programs children watch. Louise Joiners said while her 14-year-old daughter and 10-year-old son enjoy reading, the television sometimes becomes a distraction. So she tries to build the situation by suggesting books the entire family will enjoy reading together, like the Harry Potter series.
Parents who do not read themselves should not depend on their children being enthusiastic about it. If parents would read to their children at least 15 minutes every day, children would not have so many problems in school. It is the parents’ job to help build that desire in their children, and of course to know what kind of books to read is also important.
1.The underlined word “distraction” means something that .
A. can improve children’s reading.
B. can make children interested
C. can make children not pay their attention
D. can help children’s right way of reading
2.In the fourth paragraph

3.If the passage is not completed, what will be written after the passage?
A. What TV programs children can watch during reading.
B. Advice is given to control their children.
C. Parents choose reading materials for their children.
D. How children improve their reading by themselves.
4.Which one would be the best title for the passage?
A. Parents Are Their Child’s First Teacher.
B. How to Improve Children’s Reading Ability.
C. Children Spend More Time Reading with Parents.

Children who spend more time outdoors may have a lower risk of becoming nearsighted, new research suggests.
In the study, researchers looked at about 1,900 schoolchildren. The scientists found that the kids who had been instructed to spend more time outdoors over three years were 23 percent less likely to develop nearsightedness during this time than those who had not been instructed to spend more time outdoors. Moreover, among the kids who did become nearsighted during the study, the degree to which their eyesight worsened was slightly smaller among those who spent more time outdoors.
The researchers selected six schools and required the children, whose average age was 7 at the start of the study, to attend one additional 60-minute class of outdoor activities during each school day for three years. The parents of these children were also encouraged to engage their children in outdoor activities after school, especially during weekends and holidays. The other half of the children, from another six schools, continued their usual activity patterns. After three years, 30.4 percent of the kids in the intervention(干预) group had become nearsighted, compared with 38.5 percent of the kids in the other group.
It is not clear exactly why spending more time outside would benefit children’s eyesight, the researchers said. However, some research has suggested that the higher levels of light intensity found outdoors may increase the release of the chemical dopamine(多巴胺) of the eye. In turn, dopamine is known to restrain（抑制） the type of growth in the eye that is associated with nearsightedness.
Based on the new results, the researchers recommend that children spend more time outdoors because of the potential benefits to their eyesight. However, it’s important to protect kids’ skin and eyes from UV light, which can be damaging.
1.What did the children in the intervention group do during each school day?
A. Attend an extra class of outdoor activities.
B. Continue to do their usual activities.
C. Spend one hour in doing eye exercises.
D. Participate in outdoor activities with parents.
2.What can be inferred about the chemical dopamine?
A. It can contribute to poor sight. B. It can damage people’s brain
C. It is beneficial to eyesight. D. It means low levels of light intensity.
3.What may be discussed in the following paragraph?
A. How to design outdoor activities for kids.
B. How to prevent kids becoming nearsighted.
C. How to protect kids’ skin and eyes from UV light.
D. How to encourage kids to join in outdoor activities.
4.Which can serve as the best title for the passage?
A. The More Time Outdoors, the Better
B. Kids May See Better if They Play Outside
C. It’s Time to Engage Kids in Outdoor Activities
D. Researchers Found a Cure for Nearsightedness
