Let’s face it: Teenagers spend hours texting, socializing on Facebook and playing video games.And it’s driving their parents nuts.

Sure, there are real dangers connected with all this screen time—everything from cyberbullying(网络欺凌) to couch-potato obesity.Not to mention driving while texting, and shortened attention spans(持续时间).

Douglas Gentile, who studies the effects of media on children, says texting, Facebook and video games are not naturally bad.Nor are they naturally better or worse than watching TV, although they do lead to different risks, such as cyberbullying.

But research has shown that the more time kids spend in front of screens—whether it’s TV or instant-messaging—the worse their school performances are.“That doesn’t mean it’s true for every kid, but it makes sense, that for every hour a kid is playing video games, it’s an hour that they’re not doing homework or reading or exploring or creating,” he said.If screen time is taking the place of doing their homework, that’s bad.But if their homework is done, well, so what?

The study also found that the more time kids spend with media, the lower their grades and levels of personal satisfaction are.Gentile said the influence of screen time on school work can be reduced by what he calls “protective factors”.Those might include good teachers and a high-performing school, love of reading, coming from a family where education is valued.“If you had all these protective factors, then that one little risk factor, who cares?”

One thing parents should worry about is the way electronic devices encourage multitasking（多任务处理).

“As adults, your response speeds up, you’re quicker to look over your shoulder and notice little noises or lights.However this is not what the kids need when they get to the classroom.Scanning to see when the next message comes may not be good for kids.The more distractions(分心的事物) you have, the worse your performance is.” Getting kids to turn off their phones, iPods in order to let them concentrate（集中) on homework is a fight worth having.

1.What statement may Gentile agree to?

A.Kids get bad marks when using Facebook.

B.TV or texting affects kids equally.

C.Kids prefer video games to books.

D.Watching TV is better than playing video games.

2.By saying “one little risk factor”, Gentile referred to ________

A.love for reading B.valuing education

C.screen time　　 　 D.good teachers

3. It can be inferred from the last paragraph that________.

A.kids can give quick answer to questions if texting

B.Multitasks aren’t really good for every kid

C.electric devices increase the attention of kids

D.kids perform well if doing many tasks together

4.What might be the most suitable title for the passage?

A.Are kids suffering cyber bullying on Facebook?

B.Are texting and Facebook worse for teens than TV?

C.Are kids willing to turn off their electric devices?

D.Are texting causing kids to lose interest in reading?

Teenagers who spend more than six hours online on school days are more likely to be lonely and skip school, according to an international study.

The study examined the home Internet use，well-being(幸福)and behaviour of 296,000 15-year-olds in 41 countries. More than one in four spent more than four hours per day online outside of school. The study found lower levels of well-being among students who spent more than six hours per day online. They were twice as likely as teenagers spending one and two hours per day online to report that they felt lonely at school. These ''extreme Internet users'' were also especially at risk of ''behaving in problematic ways at school, such as arriving late or skipping class''.

The report said, ''Lower levels of engagement(密切关系)with school may be connected to less sense of belonging at school. It is also possible that skipping class and arriving late for school are the consequence of lack of sleep among extreme Internet users. '' It adds，'' Parents， schools and health professionals can work together to watch and plan children's use of new media. ''

The study also found that countries that invest (投资)heavily in Information and Communication Technology (ICT) in schools have seen no ''considerable'' difference in 15-year-olds5 achievement in reading, math or science tests. The study results suggest ''limited'' use of computers at school ''may be better'' than not using them at all. However, students who use computers ''very frequently'' at school ''do a lot worse in most learning outcomes''. The report says，'' In the end，technology can strengthen great teaching，but great technology cannot replace poor teaching. ''

1.The international study showed that　　　　 .

A.half of the students spent six hours online every day

B.extreme Internet users had lower levels of well-being

C.teenagers spent much time online when they felt lonely

D.most of the students were late for school after extreme Internet use

2.What can we learn from the study results?

A.Schools should invest more in ICT.

B.Proper use of computers is helpful at school.

C.Technology sometimes leads to poor teaching.

D.Computer users perform well in maths at school.

3.Where does this text most probably come from?

Teenagers who check social media for several hours a day are at the risk ofdeveloping ADHD (多动症), a study has concluded.

The research team, from the University of Southern California, tracked 2,600teenagers aged 15 and 16. They asked them how many times they checked theirphones and other digital devices for various reasons, and then monitored them for symptoms of ADHD. After two years, those who had checked their phones the mostoften were twice as likely as those who checked the least often to show signs ofADHD.

Writing in the JAMA medical journal, the scientists said, “Modern mediadevices immediately inform users when new text messages, social media postings, or videogame play invitations arrive. Exposure to such information may drawattention away from important tasks. Frequent distraction could interrupt thedevelopment of constant attention and organization skills.”

They believe constant access to instant entertainment also has an impact. Researcher Professor Adam Leventhal said all previous research had focused on the link between ADHD and televisions. “What’s new is that previous studies on thistopic were done many years ago, when social media, mobile phones, tablets andmobile apps didn’t exist. We can say with confidence that teens who are exposedto higher levels of digital media are significantly more likely to develop ADHDsymptoms in the future,” he said.

Leventhal believes the findings help fill a gap in understanding how newmobile media devices and seemingly limitless content pose a mental health risk forchildren. And the findings serve as a warning.

British scientists welcomed the findings. But Professor Andy Przybylski of theOxford Internet Institute said, “The study relies on survey responses provided bythe students in question. It is not clear if teachers or parents would rate the childrensimilarly or if the self-reported measure of digital screen use is related with eitheractual behavior or higher quality survey items.”

1.How did the researchers conduct the study?

A.By monitoring 2,600 teenagers with ADHD.

B.By tracking the participants for two years.

C.By analyzing data from previous researches online.

D.By controlling different teens’ time spent on social media.

2.What does Leventhal think of the exposure to higher levels of digital media?

A.It will cause diverse ADHD symptoms.

B.It will create higher ADHD risks.

C.It will weaken teenagers’ confidence.

D.It will have a major influence on organization skills.

3.What does Professor Andy Przybylski think of the study?

A.It provides a better understanding of the media.

B.It should have focused on parents’ responses.

C.Its findings are not reliable enough.

D.It’s a breakthrough in this field.

4.What can be a suitable title for the text?

A.The use of digital media is on the rise

B.Teens are increasingly exposed to ADHD

C.Heavy use of social media may increase ADHD risks

D.Teens’ exposure to modern media calls more attention

Many people spend more than four hours per day on We Chat, and it is redefining the word “friend.” Does friending someone on social media make him or her your friend in real life?

Robin Dunbar, a professor at Oxford University, found that only 15, of the 150 Facebook friends the average user has, could be counted as actual friends and only five as close friends. We Chat may show a similar pattern.

Those with whom you attended a course together, applied for the same part-time job, went to a party and intended to cooperate but failed take up most of your WeChat friends. In chat records, the only message may be a system notice, “You have accepted somebody’s friend request”. Sometimes when seeing some photos shared on “Moments”, you even need several minutes to think about when you became friends. Also, you may be disturbed by mass messages (群发信息) sent from your unfamiliar “friends”, including requests for voting for their children or friends, links from Pinduoduo.com (a Chinese e-commerce platform that allows users to buy items at lower prices if they purchase in groups) and cookie-cutter (千篇一律的) blessings in holidays.

You would have thought about deleting this type of “friends” and sort out your connections. But actually you did not do that as you were taught that social networking is valuable to one’s success. Besides, it would be really awkward if they found that you have unfriended them already. Then, you keep increasing your “friends” in social media and click “like” on some pictures that you are not really interested. But the fact is that deep emotional connections do not come with the increasing number of your friends in social media.

If the number of your friends reaches 150, maintaining these relationships can be tough to you, and sometimes even will make you anxious. According to Robin Dunbar, 150 is the limit of the number of people with whom one can maintain stable social relationships.

1.What can we learn from Robin Dunbar's finding in Paragraph 2?

A. A Facebook user has 250 friends on average.

B. Most of the social media friends can be actual friends.

C. Among our social media friends, only a few people matter.

D. Only 15 people of a person’s Facebook friends can be close friends.

2.What does the third paragraph tell us about most of your WeChat friends?

A. You have deep communication with them.

B. You benefit a lot from their mass messages.

C. You just have a nodding acquaintance with them.

D. You become friends with them in important occasions.

3.What does the underlined word “that” in Paragraph 4 refer to?

A. Removing unfamiliar friends in WeChat.

B. Strengthening ties with your We Chat friends.

C. Keeping increasing your friends in social media.

D. Clicking “like” on pictures posted by your friends.

4.What can we infer from the last paragraph?

A. We will be anxious if we make friends online.

B. We should avoid making any friends in social media.

C. We should make as many friends as possible in social media.

D. We have difficulty managing relationships with over 150 people.

Keeping a busy social life among lots of friends may keep people thinner than spending hours doing some exercises, according to scientists. They say that socializing and meeting with friends help increase levels of brown fat in the body which burns calories to produce heat.

Living in an exciting social environment was found to reduce fat in mice's belly by half over four weeks, even if they ate more. US researchers say that social excitement aids weight loss by turning white fat into brown. White fat stores calories and makes us fatter, while brown burns energy to produce heat. Turning white fat into brown is extremely difficult, normally requiring long- term stay in cold conditions or exciting part of the body's nervous system.　

However, scientists from Ohio State University now think that having a busy social life is an even more effective way of changing white fat into brown. The team came up with their theory by studying the effects of various living environments on mice. Those, who lived alongside a greater number of mice, had more space and toys to excite themselves and then lost far more weight over the course of the study than their “couch potato" fellows.

Study author, Dr Matthew During, whose team’s findings appear in the journal Cell Metabolism, said, “I'm still amazed at the degree of fat loss that occurs.” explaining how new technology had threatened face-to-face socializing, he added, “It's not just a sedentary(久坐的) lifestyle and high calorie foods, but an increasing lack of social activities.” Co-author Dr Lei Cao said，“Loneliness is a potential factor for cancer and death; it's equal to cigarette smoking to a certain extent. Social activities are very vital.”

1.What information can we get from the first two paragraphs?

A. Brown fat stores calories and makes us fatter.

B. It doesn’t take long to turn white fat into brown.

C. Brown fat can burn energy to produce heat.

D. Social excitement helps gain more weight.

2.Which of the following statement does the text support?

A. The mice lacking social life lose more weight.

B. Levels of brown fat can be increased by socializing.

C. The research findings haven’t been published so far.

D. Dr Matthew During wasn’t convinced of the result.

3.We can conclude from the text that _______.

A. the fat in mice’s belly was reduced because of the relaxing environment

B. a sedentary lifestyle and high calories foods influence people’s social life

C. surfing the Internet may influence people’s face-to-face communication

D. cancer and death are mainly caused for lack of social life

4. What’s the main idea of the text?

A. Socializing contributes to people's losing weight

B. Socializing is unnecessarily important in people’s daily life.

C. White fat can be changed into brown fat.

D. Brown fat is beneficial to people’s health.

Texting is a great way to communicate and teenagers are doing just that. New research shows that on average, teens are sending 2,000 text messages a month, and doctors say it’s causing injuries.

13-year-old Bailey Baker keeps using her thumbs, sending text messages to her friends again and again. The past March may have been her best month ever, texting 8,000 times. Now, she says she’s feeling the pain. “Just mainly back and neck problems and thumb numbness,” she says.

Baylor-Garland Dr. Jane Sadler is seeing more and more teens who simply text until it hurts. She says parents, including Bailey’s mom, have no idea how much their kids are texting. “I was thinking she was texting about 25 texts a day,” says Lisa Baker. “Wrong! We’ve uncovered a problem.” It didn’t take Dr. Sadler long to find the problem. She gave Bailey the once-over and learnt that Bailey had developed Texting Teen Tendinitis(肌腱炎)

“A lot of them report pain in their thumbs, back and neck,” says Dr. Sadler. “When we look into it and examine a little bit further, we see texting is the main cause of the problem.” Dr. Sadler says back pain is caused by poor posture while texting. Bailey often texts for up to 2 hours a day; that’s a lot of wear and tear on the thumbs which over time, can break down. Dr. Sadler tells over-texting teens to look into the future. “What I tell them is ‘Hey, you might be normal now, but when you are 40 or 50, you can get arthritis (关节炎).’”

Dr. Sadler recommends limiting texting to 50 a day, and keeping good posture. Dr. Sadler also says touch screens are easier on the thumbs than keyboards and hand exercises are great to build up those muscles, making it easier to text.

1. How many text messages did Bailey Baker send a day on average last month?

A. Less than 226.     B. About 230.            C. About 267.            D. More than 300.

请阅读下面短文，并按照要求用英语写一篇150词左右的文章。

It's a question every social­media user faces after taking a great photo: Should I post this? Or is it going to come back to worry me? The questions get doubly complex when they involve children. A parent on average will post almost 1，000 photos of a child online before the child turns five, according to a recent survey. Are parents putting kids at risk by oversharing on social media?

Here are the selections of the views.

Lauren Apfel(US)

The big reason to share is to build a community. I live, for example, thousands of miles from my family. In this atmosphere of modern parenthood, we all struggle to make it through the day, and the Internet has become a source of support. In the early years of mothering twins, one of the things that brought me the most happiness was posting pictures of them on Facebook. Sharing those photos and engaging with an online community was a lifeline.

Dracarys(China)

I don't post pictures of my kids online because I don't like when friends of mine post photos of me online. It feels way too public and exhibitionist to me. So I treat my kids the way I want to be treated. That is probably what the parents who are comfortable with online photos think, too, when they decide to put the photos out there.

（写作内容）

1. 用约30个单词写出上文概要。

2. 用约120个单词阐述你对家长在社交网络上分享孩子照片的看法，并用2—3个理由或论据支撑你的理由。

（写作要求）

1. 写作过程中不能直接引用原文语句。

2. 作文中不能出现真实姓名和学校名称。

3. 不必写标题

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项多余选项。

It’s not news that we spend more time than ever texting and online.1 Yes, that’s right: a 2010 study shows that more teens are reading good old-fashioned, ink-on-paper books.

Reading is a good way to discover the next big thing and to learn a little more about yourself while you’re at it.2 Here are some tips.

Start with your interests

Reading on your own isn’t like reading for school. You can pick something that’s all about your interests, whether it’s ancient martial arts, computers, or fashion design.

Reading the blurbs(简介)

The reviews and quotes on the back and inside covers of many books are called “blurbs”. 3if you find a book you really like, take a minute to read the quotes(if there are any) and see which authors praised the book. Often, they’ll have similar styles and you might find you like books by those authors too.

Ask an expert

4 Explain your interests--- rock stars, sports teams, historical events, humors, whatever you’re into—and any writers you like, and your librarian can point you toward books that you’ll love.

Finally, you’ll probably enjoy what you’re reading a lot more if you find a quiet place and make time for the book.5 You can put on some good music(ideally without lyrics), get yourself some tea and a comfy spot, and let yourself be carried away by the book.

You’ll see that time does fly when you are reading something you love!

A．Join a group with your friends and people you trust.

B．But do you know how to pick a book you’ll really like?

C．But did you know that we also spend more time reading?

D．Your local library can hook you up with a whole lot of great book ideas.

E. What was your mother’s favorite book when she was your age or your dad’s?

F. We all multitask, but most reading is best enjoyed when you can concentrate and focus on it.

G. They give you an idea of what the book is about, and can also help you pick future books too.
