Researchers found that compared with teens who spent much of their free time in front of TV sets, those who were physically active often had higher self-respect, better grades and were less likely to have risky behavior like taking drugs, smoking, or drinking．The findings, based on a national survey of nearly 12,000 middle and high school students, were published in a journal．
"Across the board, children who engaged in any kind of activity were belier off than kids who watched a lot of TV," said study co author professor Penny Gordon Larsen of the University of North Carolina．
Other studies have linked certain content of television programs, such as violence and sex, to children's behavior．But beyond this issue, Gordon-Larsen said that kids who spend hours watching TV "miss opportunities" to develop skills, learn teamwork and have other experiences that their more active peers benefit from．
That doesn't mean, however, that kids have to be on the football team． The study found that some activities like skating and skateboarding——which adults sometimes frown upon——were also related to better self respect and less risk taking．
That skaters were better behaved than TV watchers might come as a surprise to some adults who consider these teens to be bad, according to Gordon-Larsen．Skateboarding is forbidden in many public areas, and some communities oppose building skating parks．But if kids who like to skate have nowhere to do it, "it's a shame," said Gordon-Larsen．
Not only should parents encourage their kids to engage iii the physical activities they enjoy, she said, but schools and communities should also do more to create opportunities for children to be active．

Do you still get free plastic bags from the supermarkets? Things have changed.
China has banned free plastic bags at shops and supermarkets, and people have to pay for using plastic bags. The rule started on June 1, 2008. It came because our country tried to make litter less. Making super-thin plastic bags has also been banned.
The Chinese once used about 3,000,000,000 plastic shopping bags a day, and they have caused pollution of the environment. The bags have become a main cause of plastic pollution because they are easy to break and people throw them away here and there. So the Chinese people are encouraged to bring their own bags for shopping.
What kind of shopping bag is the best to bring? Some students in Anhui have a good idea. They make their own shopping bags. They use old clothes to make cloth bags, and send them to their parents as presents. They also ask their parents and friends to use cloth bags instead of plastic ones. They think it is their duty to protect the environment.

Findings from a new study were presented at a recent meeting of the American Psychosomatic(身心的) Society. Researchers in the United States studied 100,000 women during an eight-year period, beginning in 1994. All of the women were fifty or older. The study was part of the Women’s Health Initiative organized by the National Institutes of Health.
The women were asked questions measuring their beliefs or ideas about the future. The researchers attempted to identify each woman’s personality eight years after gathering the information.
The study found that hopeful individuals were 14% less likely than other women to have died from any cause. The hopeful women were also 30% less likely to have died from heart disease after the eight years.
Hilary Tindle from the University of Pittsburgh in Pennsylvania was the lead author of the report. She said the study confirmed earlier research that linked optimistic feelings to longer life.
The researchers also gathered information about people’s education, financial earnings, physical activity and use of alcohol or cigarettes. Independent of those things, the findings still showed that optimists had less of a chance of dying during the eight-year period.
Some women who answered the questions were found to be hostile (怀敌意的), or highly untrusting of others. These women were 16% more likely to die than the others. They also were 23% more likely to die of cancer.
The study also found women who were not optimistic were more likely to smoke and have high blood pressure or diabetes. They were also more likely not to exercise.
Tindle says the study did not confirm whether optimism leads to healthier choices, or if it actually affects a person’s physical health. She also says the study does not prove that negative (消极的) emotions or distrust lead to bad health effects and shorter life. Yet there does appear to be a link that calls for more research.

Imagine one day, the water taps in your house stop running. You have to buy water from shops. And still there isn’t enough for everyone. Your mother has to save the family’s shower water to do other things. Would you be able to stand that kind of life?
Probably not. But that’s what kids in Yemen are experiencing. Experts said Yemen is going to be the first country in the world to run out of water. According to a report, the capital, Sanaa, will run out of drinking water as early as 2025.
Because of the shortage, the government often cuts the water supply. Hannan, an 18-year-old from Lahej, told the Times: “In a good week we’ll have a water supply all week. But then the following week there will be water only for a day or two.”
Hannan said only rich people have enough water to use. They can buy water from the shops or from the water truck. Private companies own the trucks. They travel around the city every day to sell water – at very high prices.
“A lot of people can’t afford it,” she said.
The average person in Yemen uses 100 to 200 cubic meters of water per year. That is far below the international water poverty line of 1,000 cubic meters.
The government is thinking of making use of seawater. But it will cost a lot and it may not happen soon enough to help the people of Yemen.

Contrary to common belief, social media websites such as Facebook do not weaken personal ties, they strengthen them in unique ways for different age groups, according to a new study．
The rapid spread of Facebook, which has more than 500 million users worldwide, has prompted concerns about its negative effects, but researchers at the University of Texas have reached a different conclusion．
"Our findings suggest that Facebook is not replacing face-to-face interactions between friends, family and colleagues," said S．Craig Watkins, an associate professor of radio, TV and film who headed the research team．
"In fact, we believe there is sufficient evidence that social media afford opportunities for new expressions of friendship, intimacy and community．"
The researchers questioned 900 college students and recent graduates about how and with whom they interact on Facebook．
More than 60 percent of Facebook users said posting status updates was among the most popular activities, followed by 60 percent who wrote comments on their profile and 49 percent who posted messages and comments to friends．
The researchers also found that although about the same number of men and women use Facebook, they do so in different ways．
"There is a noteworthy difference in aims in how to use a tool like Facebook．We found that for women the content tends to be more affectionate, and （they） are especially interested in using it for connection," said Watkins．
"For men, it's more functional," he added．
Watkins pointed out that, for example, women are more likely to post pictures of social gatherings with friends, while men are more likely to post pictures of hobbies, or post a political or pop-culture related link．
【小题1】What's the popular viewpoint of ordinary people about the function of social media websites? They think ____．

A．It is positive to personal ties

B．It has negative effects on personal ties

C．It makes no difference to personal ties

D．It has both good and bad effects to personal ties

C．update their personal statuses

D．post messages and comments to friends

【小题4】According to the study, ____．

A．Men concentrate more on the functions of Facebook

B．Much more men use Facebook than women

C．Men and women use a tool like Facebook for the same aim

D．Facebook is taking the place of face-to-face interactions between friends

Few of us make money by losing sleep．But three graduate students at Brown University in Providence built a company around sleep deprivation （睡眠不足）．
Jason Donahue, Ben Rubin and Eric Shashoua were working late nights in Brown's business and engineering schools．They began thinking about ways to sleep better．They discovered they weren't alone in burning the midnight oil．Around 20% of Americans get less than six hours of rest a night．
The friends imagined a smart alarm clock that could track how much time people spend in the most restorative （有回复作用的） stages of the sleep cycle: REM （rapid eye movement） and deep sleep．What would it cost to design such a thing? Five years of research, 20 employees, $14 million and a whole lot of doubting from investors and scientists．
Their company, Zeo, based in Newton, Mass, launched its product in June, 2009．The Zeo device uses a headband with tiny sensors （传感器） that scan your brain for signs of four sleep states- REM, light, deep and waking sleep．The smart alarm clock displays a graph of your sleep pattern and wakes you as you're not in REM sleep （which is when you're least groggy）．In the morning you can upload the data to the company's Web site, and so track your sleep over time．Most of the feedback comes in the form of Zeo's ZQ score showing how well you've slept．
"Zeo allows people to unlock this black box of sleep," says Dave Dickinson, a health-care CEO．
Whether any of this actually improves sleep is up to the consumer, who will also need to make lifestyle changes like cutting out alcohol before bedtime or caffeine after 3 pm．
For now the company is selling Zeo online only．Dickinson also plans to spread it to countries such as Australia, where sleep deprivation approaches US levels．
【小题1】Who will support Zeo?

A．People full of imagination．	B．People suffering sleeping problems．
C．People having access to the Internet．	D．People having bad lifestyles．

【小题2】Why did the three graduate students imagine a smart alarm clock?

A．To wake them up on time in the morning．

B．To earn enough money for their study．

C．To improve the quality of people's sleep．

D．To enjoy their life while working at night．

【小题3】To design the Zeo device, the three graduate students ____．

A．spent much time and money	B．were widely supported by scientists
C．worked by themselves all the time	D．attracted many investors

【小题4】What can we know from the passage?

A．Zeo has a direct effect on users' lifestyles．

B．It needs more personal efforts to make Zeo function better．

C．A large quantity of Zeo devices have been sold in Australia．

D．Consumers can go to the Zeo company to purchase Zeo in person．

OK, I admit it: emoticons (表情符号) are popular. Some people even think they are fun. Many seem unable to get through an e-mail or Instant Message chat sentence without using one. Some feel that they add feeling and character to otherwise cold digital communications.
Some, however, such as editor and Hollywood scriptwriter John Blumenthal, blast (抨击) the use of emoticons as “infantile (幼稚的) just like the people who use them”  He believes that words themselves should be enough. “If you’re being funny, happy or sad, that should be apparent (明显的) from the comment that goes before the emoticon,” he argues.
In the eyes of Blumenthal, the use of emoticons is a gender issue. “Men don’t use emoticons very much. Maybe not at all,” he said. “Teenage girls and women seem to use them a lot. Maybe there’ s an emoticon gene.”
It’s an interesting opinion, but it is not shared by all.
In an interview with The New York Times, Dacher Keltner, professor of psychology at the University of California, said that emoticons are popular because our brains are programmed “to seek out representations of humanity”. He believes that they appeal not because they are shortcuts for the lazy, but because they tap into (融入) something beyond language. They reach to our need to be with and communicate with people.
All of these arguments may be somehow valid (正确的). Each one of us will choose to communicate in our own way. I do not have much time for emoticons. I tried to use one once and felt like I was stealing into a primary school class that I had no place being in. I’d rather let my words do the talking.
Friends, however, send me messages and e-mails full of emoticons. I have no problem with this. I don’t regard any of my friends as lazy or immature (不成熟的). It’s just a question of individuality. :)
【小题1】According to the article, emoticons are popular because ______. 

A．most of them look funny

B．they are easy for lazy people to use

C．they add feeling and character to a communication

【小题3】From the text, we can conclude that the author ______. 

A．feels he has no difficulty using emoticons

B．thinks emoticons don’t suit him

C．encourage his friends to use emoticons

D．believes that emoticons are suitable for everyone

【小题4】What is the main point of the article? 

A．Advice on language used over the Internet.

B．The history of emoticons.

C．Arguments over the use of emoticons.

D．Reasons for the popularity of emoticons.

Humanity uses a little less than half the water available worldwide. Yet occurrences of shortages and droughts (干旱) are causing famine and distress in some areas, and industrial and agricultural by-products are polluting water supplies. Since the world’s population is expected to double in the next 50 years, many experts think we are on the edge of a widespread water crisis.
　 But that doesn’t have to be the outcome. Water shortages do not have to trouble the world---if we start valuing water more than we did in the past. Just as we began to appreciate petroleum more after the 1970s oil crises, today we must start looking at water from a fresh economic perspective. We can no longer afford to consider water a virtually free resource of which we can use as much as we like in any way we want.
　 Instead, for all uses except the domestic demand of the poor, governments should price water to reflect its actual value. This means charging a fee for the water itself as well as for the supply costs.
　 Governments should also protect this resource by providing water in more economically and environmentally sound (健康的) ways. For example, often the cheapest way to provide irrigation water in the dry tropics is through small-scale projects, such as gathering rainfall in depressions (凹地) and pumping it to nearby cropland.
　 No matter what steps governments take to provide water more efficiently, they must change their institutional and legal approaches to water use. Rather than spread control among hundreds or even thousands of local, regional, and national agencies that watch various aspects of water use, countries should set up central authorities to coordinate (调整) water policy.
【小题1】What is the real cause of the potentials water crisis.

A．Only half of the world’s water can be used.

B．The world population is increasing faster and faster.

C．Half of the world’s water resources have been seriously polluted.

D．Humanity has not placed enough value on water resources.

【小题2】As is indicated in the passage, the water problem _________ .

A．is already serious in certain parts of the world.

B．has been exaggerated by some experts in the field

C．poses a challenge to the technology of building reservoirs(水库)

D．is underestimated by government organizations at different levels

【小题3】 According to the author, the water price should _______ .

A．be reduced to the minimum	B．stimulate domestic demand
C．go with its real value	D．take into account the occurrences of droughts

【小题4】In order to raise the efficiency of the water supply, measures should be taken to ______ .

A．guarantee full protection of the environment

B．centralize the management of water resources

C．increase the sense of responsibility of agencies at all levels

D．encourage local and regional water resources

Hungry for the brightest students, many of the country’s stronger universities are actively discounting tuition （学费）．And it’s the high achievers, rather than the needy students, who are getting a good chunk of the money．The practice is remarkably widespread, reaching almost all but the 30 or so Ivy and other top colleges that forbid good grades-based financial aid．Schools are also becoming more aggressive in raising their discounts．At the DePauw University Website, enter an SAT or ACT score, grade point average and class rank, and a computer program immediately tells you what kind of "award"．Only "the real unlucky" pay full price any more．
About 76% of first-year students got some form of discount this year at 331 private schools．Average award per student: $7,000．At small schools with tuition under about $20,000, the average discount is even higher, with some schools returning over half their tuition．                                                         
Carnegie Mellon even tells students it will "negotiate（讨价还价）" and perhaps match financial-aid packages if kids are offered bigger awards at other schools．Much as banks and insurers offer special rates to their best customers, schools are giving the biggest breaks to their top students．Public four-year colleges, too, are offering discounts．
The flip side of big discounts is that less money is available to improve academic programs and keep school infrastructure （基础设施） up to date．Universities that have sharply increased their tuition discount rates have seen graduation rates fall, and that’s true even among highly selective schools．They get the students in the door, but don’t have the services to keep them．
【小题1】From the first paragraph, we can judge that _______．

A．all the universities don’t offer tuition discounts．

B．Ivy and other top colleges offer financial aid to the high achievers

C．the needy students get more money from the universities

D．the graduation rates of the students from highly selected schools fall

【小题2】The underlined words “flip side” in the last paragraph probably mean “_______”．

A．advantage

B．disadvantage

C．bad practice

D．good function

【小题3】Which of the following statements is TRUE according to the passage?

A．The brightest students are not at all hungry for stronger universities．

B．About 76% of first-year students got an award of $ 20,000 per year．

C．Public colleges never offer discounts to the students．

D．Colleges should concentrate more on the services to keep the students

【小题4】This passage mainly talks about _______．

A．the great benefit of offering lower tuition

B．college tuition discounts in popularity

C．the top students in need of tuition discounts

D．reducing graduation rates due to big discounts

To switch or not to switch, that is the question．Google’s announcement of its Nexus One smartphone（智能手机） happened over a week ago and I’m still receiving lots of e-mails from readers asking the same question: Should they give up their iPhone for the Nexus One?
Some people with iPhones, disappointed by American Telephone&Telegraph’s inadequate service and the high monthly cost, are wondering if they have really got something to replace it．Does the Nexus One offer the functions that Apple has led them to expect?
I’m on the fence myself, even though I never thought I’d be interested in anything but the iPhone．From my experience using the Nexus One, and from talking to people who have made the change, it’s not necessarily about the differences between the iPhone and the Nexus One．The phones are extremely similar in design and general feel．Instead, the decision can be made based on the software（软件） services you use on your desktop．
My friend Chad Dickerson received a pre-launch Nexus One from Google three weeks ago．He said Google’s phone feels connected to certain services on the Web in a way the iPhone doesn’t．“Compared to the iPhone, the Google phone feels like it’s part of the Internet to me,” he said．“If you live in a Google world, you have that world in your pocket in a way that’s cleaner and more connected than the iPhone．”
Personally, the phones work perfectly with their own software, but both of them don’t make an effort to play well with other services．
【小题1】Why are some iPhone users expecting a new type of phone?

A．Because their old ones are out of date．

B．Because they accept Google’s announcement．

C．Because of the limited service and high cost．

D．Because of the terrible software they can use．．

【小题2】What’s the author’s attitude towards the new phones in the third paragraph?

A．Negative

B．Neutral

C．Indifferent

D．Positive

【小题3】In Chad Dickerson’s opinion, the Nexus One is ________ the iPhone．

A．better than

B．worse than

C．as good as

D．as bad as

【小题4】The best title of the passage might be ________．

A．Apple’s New Smartphone

B．Torn Between Two Phones

C．Good Services Matter

D．Google’s New Smartphone
