Teens who become addicted to their cell phones may be placing their health at risk by harming their ability to sleep well,a new Swedish study suggests.
"The message is that teenagers who use their cell phones excessively are much more stressed, much more restless, much more tired, and have a great tendency to develop sleep deprivation(剥夺) as a result of their calling habits, " said the study author Dr. Gaby Bader.
He focused on the experiences of 21 healthy Swedish boys and girls between the ages of 14 and 20. The teens kept what the authors described as "regular working/studying hours" and were not previously diagnosed with any particular sleep irregularity.
He observed that the above-15 call group kept more irregular sleeping hours than the lower-use group,had more difficulty falling asleep,more difficulty waking up,and experienced more sleep disruptions(扰乱).
Bader said that among young people,a relatively recent technological invention like the cell phone has quickly become existed nearly everywhere,giving rise to considerable pressure to keep in touch. And this pressure can develop into an addiction,with serious negative results for teenager health.
"We see more and more people--especially the young generation-- who grew up with these kinds of items and gadgets in their hands," Bader said. "And they become dependent on the technology. So,we have to teach young people to be structured. To know when to have the cell phone on,and when to switch it off. To avoid becoming the slave of technology,instead of the master. "
Dr. Mary Carskadon expressed little surprise with the finding. " Interpersonal(人际的)contact is one of the things that's best at keeping us awake," she observed. "And so,a young person receiving cell phone texts or phone calls is going to have more deep disturbances. And they are going to be tired and restless,and probably,as a result,going to use more stimulants(兴奋剂).And judgment is not always the best in our teenage years. So, that's where I think parental attention to this issue may be useful. "
72. Teens who become addicted to their cell phones will become .
A. too anxious to relax. B. unable to stay still.
C. unable to have real rest. D. excited to forget sleep.
73. What we can learn from the sixth paragraph is that .
A. more teens know how to make technology serve them
B. teens used to be taught how to use technology
C. we should make use of technology rather than be in the control of it
D. the young generation depends less on the technology to grow up

A. Teenagers should judge how to use their phones.
B. Teenagers should reduce their interpersonal contact.
C. Teenagers should switch their phones off.
D. Parents should give more attention to children's use of phones.
75.What's the passage mainly about?
A. Too much phone time has a bad effect on teens' sleep.

Teenagers who talk on the cell phone a lot, and hold their phones up to their right ears, score worse on one type of memory test. That’s the finding of a new study. That memory impairment might be one side effect of the radiation (放射线) that phones use to keep us connected while we’re on the go.
Nearly 700 Swiss teens took part in a test of figural memory. This type helps us remember abstract (抽象的) symbols and shapes, explains Milena Foerster. The teens took memory tests twice, one year apart. Each time, they had one minute to remember 13 pairs of abstract shapes. Then they were shown one item from each pair and asked to match it with one of the five choices. The study volunteers also took a test of verbal memory. That’s the ability to remember words. The two memory tests are part of an intelligence test. The researchers also surveyed the teens on how they use cell phones. And they got call records from phone companies. The researchers used those records to figure out how long the teens were using their phones. This allowed the researchers to work out how big a radiation exposure (接触) each person could have got while talking.
A phone user’s exposure to the radiation can differ widely. Some teens talk on their phones more than others. People also hold their phones differently. If the phone is close to the ear, more radiation may enter the body, Foerster notes. Even the type of network signal that a phone uses can matter. Much of Switzerland was using an older “second-generation” type of cell phone networks, the study reports. Many phone carriers (通讯公司) have moved away from such networks. And more companies plan to update their networks within the next few years.
The teens’ scores in the figural memory tests were roughly the same from one year to the next. But those who normally held their phones near the right ears, and who were also exposed to higher levels of radiation, scored a little bit worse after a year. No group of teens showed big changes on the verbal memory test. Why might one type of memory be linked to cell phone use, but not another? Foerster thinks it could have to do with where different memory centers sit in the brain. The site that deals with the ability to remember shapes is near the right ear.
1.According to Paragraph 2, which of the following is TRUE?
A.The teens took two types of memory tests four times in total.
B.The teens needed to report the average time spent on their phones.
C.Researchers paid little attention to the teens’ habits of using phones.
D.The teens’ ability of remembering words is shown in figural memory test.
2.What can we infer from Paragraph 3?
A.How people hold their phones has no effect on their bodies.
B.Phone users can make more money with new networks.
C.The cell phone network type has little to do the cell phone use.
D.Radiation levels are affected by the cell phone network types.
3.According to the study, teens who use their phones to their right ears a lot do worse in ________.
A.matching numbers B.reading signals
C.remembering shapes D.learning words
4.What might be the best title for the text?
A.Cell phone use and safety warnings
B.Facts about cell phone use at school
C.Dangerous levels of cell phone use among teens
D.Teen’s cell phone use linked to memory problems

The round-the-clock availability that cell phones have brought to people’s lives may be taking a toll on family life, a new study suggests. The study, which followed more than 1300 adults over 2 years, found that those who consistently used a mobile phone through out the study period were more likely to report negative “spillover” between work and home life—and, in turn, less satisfaction with their family life.
Spillover(影响,后果) actually means that the line between work and home began to become unclear. Work life may invade home life—when a parent is taking job-related calls at home, for instance—or family issues may start to take up work time. For example, a child may call Mom at work, telling her “the microwave exploded”, explained Noelle Chesley, an assistant professor of society at the University of Wisconsin Milwaukee and the author of the study. The problem with cell phones seems to be they are allowing for ever more spillover between work and home.
This may be especially true for working women, the study found. Among men, consistent use of mobile phones seemed not to allow more work issues to creep(潜入) into family time. But for women, the spillover tended to go in both directions—being “connected” means that work cuts into home time, and family issues come into work life.
Cell phones seem to be opening more lines for stressful exchange among family members. But there may be ways to control the spillover, according to Chesley. Employers, she said, should look at their policies on contacting employees after working hours to make sure their expectations are “reasonable”. For their part, employees can decide that cell phones go off during family time, Chesley said.
1.Which of the following can replace the underlined phrase “taking a toll on” in Paragraph l?
A.Explaining B.Protecting C.Extending D.Damaging
2.The example “the microwave exploded” in Paragraph 2 is used to________.
A.show the microwave is of poor quality
B.indicate how dependent the child is
C.indicate family issues affect work hours
D.show work time creeps into family life
3.What is the main idea of this passage?
A.Cell phones offer 24-hour availability.
B.Cell phones get life and work mixed.
C.Women don’t use cell phones in an effective way.
D.Men are better at dealing with family problems.
4.What is the author’s attitude towards round-the-clock availability of the cell phone?
A.Curious B.Positive C.Subjective D.Objective

Parents of children and teens who play football may worry about their bodies getting injury. Younger football players have the lowest chance of injury. 1. Therefore, it’s necessary for players to know the rules of playing football whether they are young or old. The following can be used to reduce the chance of injuries while players are still enjoying the game.
2. The American Academy of Pediatrics advises players and their families talk about whether the risks of injury outweighs the benefits of playing football. Football has many benefits, including regular exercise, learning to be part of a team,and social growth and development. Families who decide to play can take steps to reduce the chances of serious injury.
Play by the rules. When players know the rules of the game—what’s legal and what’s not—fewer injuries happen. 3. For example, players should know that in football they can’t come from behind, crash into a player’s legs, and steal the ball. It’s legal and safer to go after the ball rather than the player.
Wear legal equipment. 4. Because illegal equipment leads to serious injuries of the head and neck. It’s also the leading cause of severe injuries in football,but remember the protection of legal equipment doesn’t depend on its quantity.
Get good training. Players should learn the right way to use a tackle (装备). 5. Correct training could lower injury for younger players. Older players could be at a greater risk of injury if they first learn to use tackle and never learn the correct skill.
A. Take steps to lower football injury.
B. Weigh the risks and benefits.
C. The more legal equipment players wear, the less injury they will get.
D. Legal equipment can give football players important protection.
E. Players should know what to expect from each other.
F. Doing this and practicing the skills often make sure players are correctly trained.
G. As players get older, stronger and faster, the chance of injury goes up.

Regret can be a terrible addiction.Those who suffer from it so often become bitter and full of self-pity.It is an emotion that serious entrepreneurs(企业家)cannot afford,they must keep moving ahead and should not look back.As Alexander Graham Bell,inventor of the telephone said: when one door closes,another opens,but we often look so long and so regretfully upon the closed door that we do not see the one which has opened for us.
Entrepreneurs must learn to manage the conflict between constant experiment,which means lots of painful mistakes and a fear of failure,which can lead to paralysis(能力丧失).
Likewise,past glory can be a killer.For example,Greg Dyke,who is a clever fellow,still looks back too much to his resignation as director-general of the BBC.He should move on and stop complaining about the injustice of it all. And Tim Waterstone should give up trying to buy back his bookshop chain,which he finally left more than lo years ago.He has tried to repurchase it at least five times.
By all means treasure experience and learn from your failure,but don't put yourself in the past sadness.Rather,go ahead and seize the day no matter what it is.I have little time for those who say: I wish I had started my own business. My only response is: so do it now.
1.According to Paragraph 1,regret can make one feel .
A. bitter and self-pity B. upset and hopeless
C. disappointed and scared D. confident and brave
2.It can be concluded from Bell's words that .

A. arguments and failure B. mistakes and fear
C. choices and changes D. encouragement and confusion
4.What is the main idea of the text?
A. One should feel regret about the past.
B. One should give oneself opportunity.
C. One should act now and look into the future.
D. One should be confident about the past.

Children are becoming addicted to social media for their sense of self-worth, a major study warned. It found many youngsters measure their status(形象) by public approval they get online, often through “likes”. Some change their conduct in real life to improve their image online.
The research into youngsters aged from 8 to 16 was carried out by Children's Commissioner(专员) Anne Longfield. She said social media firms were exposing children to major psychological risks, with some youngsters starting secondary school ill-equipped to deal with the huge pressure they faced online. Youngsters felt their friendships could be at risk, not responding to social media posts quickly and around the clock.
Children aged 8 to 10 were "starting to feel happy" when others liked their posts. However, those in the 10 to 12 age group were "concerned with how many people like their posts", indicating a “need” for social recognition that gets stronger the older they become.
Children tended to compare themselves to others online. "Then there is this push to connect—if offline, will you miss something, will you miss out, will you show you don't care about those you are following, all come together in a huge way at once." Miss Longfield said, "For children it’s very difficult to handle." The Commissioner found children as young as 8 were using social media platforms largely for fun.
However, the research—involving eight groups of 32 children aged 8 to 12—suggested that as they grew, they became increasingly anxious online. When they started secondary school—at age 11—children were already far more conscious of their image online and felt more pressure to ensure popularity of their posts, the research found.
Meanwhile, they still did not know how to dispose of mean-spirited jokes, or the possible sense of inability if compared with celebrities(名人) or more brilliant friends online. They also faced pressure to respond to messages at all hours of the day—especially at secondary school when more youngsters have mobile phones.
The Commissioner advocated schools and parents do more to prepare children for the emotional minefield(雷区) . "It's vital that new age-appropriate relationship and sex education lessons help equip children to deal with growing demands of social media.” Social media companies must "take more responsibility" and monitor websites better or adjust their websites to the needs of youngsters.
1.What may account for Children’s addiction to social media?
A.To get their status recognized. B.To reduce psychological risks.
C.To change their conduct in real life. D.To deal with huge emotional pressure.
2.How was the research conducted?
A.It covered children of all ages.
B.It sought assistance help from parents.
C.It was sponsored by social media companies.
D.It divided children into groups and compared them.
3.During the process of addiction, children have a tendency to ________.
A.switch off from social media platforms
B.become less conscious of their image online
C.pick up anxiety and pressure steadily while becoming older
D.develop skills to dispose of mean-spirited jokes and the sense of loss
4.How should the problem solved according to Anne Longfield ?
A.Children should be banned from visiting the web.
B.Schools must keep track of children's use of social media.
C.It demands cooperation among families, schools and companies.
D.Social media companies need to create more apps to satisfy youngsters.

Today, when a fire breaks out, you can be sure a citizen with a cell-phone camera has posted it to Facebook or Twitter, or sent it to the media. But up to now, that citizen has not been able to easily send images and details of what is happening to the people who need it most: police, firefighters and building-security people who must respond, and whose ability to help is often measured in minutes, if not seconds.
That's about to change. A one-year old company called Elerts has developed a system that's designed to mobile and social technologies to speed the flow of information between citizens and emergency workers in time of danger. The system involves free mobile applications—iPhone and iPad app(应用软件)is available now—that eyewitnesses can use to report incidents and get public-safety warnings. And Elerts is offering a management console(控制台)for security firms and universities to receive the reports and distribute warnings and instructions, like a map with the best evacuation route(疏散路线).
The service is the brainchild of Chris Russo, deputy fire chief in the coastal town of Hull, Mass. As mobile communications sped up, he grew increasingly frustrated by his inability to communicate effectively with colleagues and the public, particularly with people who are at the scene and might be able to provide help.
"Remembering situations when communications failed puts a pit in my stomach," Mr. Russo says. Last summer, he was in a search at a beach for a missing boy, who went into a bathhouse but didn't come out. First responders feared an abduction (绑架) on the beach or shark attack. The child's mother, who didn't speak English well, was so sad that she couldn't remember what color shorts he had on. Mr. Russo had no photo of the child, and no ability to turn to beachgoers.
Two long hours later, the boy was spotted by a low-flying helicopter lost and alone on the beach crying—a lucky break. "If 5 percent of beachgoers had an app to receive a message and send in sightings of a lost boy, the happy ending might have come much sooner," Mr. Russo said.
1.What is the passage mainly about?
A. A moving story of Chris Russo. B. An app for reporting emergency.
C. A cell-phone instant service. D. An app for firm management.
2.What does the underlined part in Paragraph 4 most probably mean?
A. Makes me feel frustrated. B. Causes a stomachache.
C. Arouses my interest. D. Leaves a hole in my stomach.
3.We can infer from the passage that emergency workers ____.
A. have to carry out rescue work in minutes
B. must send images and details immediately
C. need images and detailed information badly
D. have to turn to Facebook and Twitter for details
4.The author takes Chris Russo's experience as an example to ____.
A. advertise his creativity in communication
B. show readers the working principle of the new system
C. make the passage more interesting to read
D. inform readers how Russo got the idea of the service

Now more and more students become volunteers. The projects may be with their school, neighborhood, or town, but the work of all volunteers is important. Students find that there are many advantages to volunteering.
First, volunteering helps others. Many people complain about problems in our society. Volunteers are part of the solution to our problems! While it is easy to complain about things that are not right, the volunteer takes action rather than complaining. When a student spends time working at a retirement (退休) home, cleaning up a park, or teaching a younger student, the volunteer makes the world a better place.
Second, being a volunteer makes students feel good about themselves. When a student volunteer knows that his or her efforts have made someone else’s life better, the volunteer feels great. Students always hear people saying that everyone should care about other people. Volunteers make it happen. Although some volunteer work is long or tiring, student volunteers end the day knowing they did the right thing. Their parents, teachers, and the public are proud of them. Knowing they did the right thing makes them feel better, even if they are tired.
Finally, students learn that volunteering is fun. A group of students might volunteer to clean up a riverbed in early spring. It is fun to be with their friends, to enjoy the weather, and to picnic later in a beautiful, clean area. Other students might read to young children in a playgroup. It is fun to spend time with children and to have them smile and laugh. No matter what their ages or talents are, every student can be a volunteer. The work of student volunteers is a powerful force that makes the world a better place.
54. The tile of this passage is ________.
A. Free-time Jobs B. Daily Activities C. School Life D. Volunteer Work
55. The writer really wants to say that ___________.
A. volunteering helps society as well as volunteers themselves
B. it is fun to spend time volunteering in a pre-school

It’s become part of the restaurant table setting: knife, fork, napkin and cell phone.
Distracted (思想不集中的) dining is the new concern with customers constantly texting friends, uploading a Weibo photo of the meal they’re about to chew down or emailing the boss. For many smart-phone users, it’s hard just to focus on the meal and company at hand.
Now, one restaurant in Los Angeles is giving diners a reason to turn off the digital world, by offering customers willing to check (寄存) their phones at the door a 5-percent discount on their bill. Owner and chef Mark Gold of Eva Restaurant, located on Beverly Boulevard near N. Gardner Street, hopes this gives customers a way to truly sit back and relax, enjoy their meal and actually talk with friends and family in person.
“For us, it’s really not about people disturbing other guests. Eva is home, and we want to create that environment of home, and we want people to connect again,” he explained. “It’s about two people sitting together and just connecting, without the distraction of a phone, and we’re trying to create an atmosphere where you come in and really enjoy the experience and the food and the company.”
