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．
小題1:From the passage we know that          .
A．physically active kids get into less trouble
B．more skating parks are being built
C．kids who spend hours watching TV benefit a lot
D．kids who have nowhere to skate tend to take drugs

Scientific discoveries have changed man’s life a great deal during the past century. First of all, they have greatly improved material well-being in several areas of life. In the field of medicine, cures for life threatening diseases have enabled people to live longer. In communication, the telephone and e-mail have made it possible for us to communicate with anyone in the world without leaving our homes or offices. Advances in transportation allow businessmen to fly across the ocean in the morning and return home the same evening. Space technology has put men on the moon. More efficient ways of using available resources, such as coal and solar power, have been explored.
Scientific discoveries have also changed man’s moral atmosphere. Ethical (倫理的) issues are raised by these discoveries. Should we keep a terminally ill person alive through drugs and machines or should we allow him to die in dignity? With advances in transportation had come the problem of pollution for nearly every major city in the world. If cities become uninhabitable, then such technical advances may come with too great a price to pay. Many people also question the wisdom of sending men to the moon when there are urgent problems that have not been solved on earth. During future years, increasing attention must be given to the moral as well as the practical applications of science.

One thing the tour books don’t tell you about London is that 2,000 of its residents are foxes , which fled the city about centuries ago after developers and pollution moved in . But now that the environment is cleaner , the foxes have come home , one of the many wild animals that have moved into urban areas around the world .
Several changes have brought wild animals to the concrete jungles . First of all , air and water quality in many cities has improved as a result of the 1970s’ pollution control efforts . meanwhile , rural areas have been built up , leaving many animals on the edges of suburban areas . In addition , conservationists have created urban wildlife shelters .
“ The number and variety of wild animals in urban areas is increasing , ” says Gomez Jones . One of the country’s largest populations of raccoons now lives in Washington , D.C. , and moose are regularly seen wandering into Maine towns . Peregrine falcons（獵鷹）dive from the window edges of buildings in the largest U.S. cities to hunt for pigeons .
For peregrine falcons , cities are actually safer than rural areas . By 1970 the birds had died out east of the Mississippi because the DDT , a widely used poison to kill insects , had made their eggs too thin to support life . That year , Tom Cade began raising the birds for release in cities , for cities afforded abundant food in the form of pigeons and contained none of the peregrines’ natural enemies .
“ Before they died out , some migrated to cities on their own because they had run out of natural habitats , ” Cade says . “ To peregrines , buildings are just like natural habitats . ” He has released about 30 birds since 1975 in New York , Baltimore , Philadelphia and Norfolk , and of the 20 pairs now living in the East , half are originally born in the city . “ A few of the young ones have gotten into trouble by falling down chimneys and crashing into window glass , but overall their adjustment has been successful . ”

It is commonly believed among many Chinese that Westerners who take “Yes’，and “No” by their facial expressions are more straightforward than Chinese. Normally Westerners don * t have to adopt Chinese ways like sweeping the floor or constantly checking the clock to indicate to a guest that it’ s time to leave. They don’ t have to hesitate in saying “No” when they are not able to, or don’ t want to, offer help to a friend in need. There is no embarrassment attached to this behavior. But it is too simple to conclude that Westerners are more direct speakers than the Chinese.
There are many occasions when the way Westerners express themselves makes Chinese look more straightforward and honest. When I was a fresh international student，the director of our program once asked students in an e-mail what we thought about a young professor. I simply said ’ “She seems to know a lot but doesn* t know how to teach. ” And the director replied with “Thank you for being honest. ”
Only years later when I better understood the new culture，I realized why I had gone too far. If that question were asked now，the reply would have three paragraphs devoted to the qualities of the professor before the last line came out — ” There are some gaps in her teaching method. ” Still tough, but at least it wouldn't be considered rude.
Indeed, the reserved social norms and the deeply - rooted “face issue" make honest speaking risky in China ； Americans have their own ways of being polite. This results partly from political correctness. It also results from several generations of people who have been told they have done well even when they have failed. It may not be unfair to suggest that many Americans are oversensitive and obsessed with a perfect self image.
So，the next time you hear about indirect Chinese，it would be worth challenging the source and pointing out that the cultural comparisons are much more complex. But maybe you should do it in a roundabout way，to be polite.
小題1:The passage mainly aims to ?
A． tell us something about culture distinctions
B． remind us of the conflicts between cultures
C． ask us to take positive attitudes to Chinese cultures
D． keep us informed of the various communications
小題2:According to the passage, the young professor lacked   .
A． confidence in her job
B． teaching experience
C． interaction with her students
m		D．responsibility for her students
小題3:   The underlined words “obsessed with" (para.4) probably means   .
A．satisfied withB．proud ofC．a(chǎn)ddicted toD．stuck in
小題4:   It can be inferred from the passage that    .
A． the writer has a good knowledge of American culture
B． Americans are much more straightforward than Chinese
C． the new professor was very angry with the writer' s comments
D． different culture backgrounds make cultures comparison complicated

What makes Americans spend nearly half their food dollars on meals away from home? The answers lie in the way Americans live today. During the first few decades of the twentieth century, canned and other convenience foods freed the family cook from full-time duty at the kitchen range. Then, in the 1940s, work in the wartime defense plants took more women out of the home than ever before, setting the pattern of the working wife and mother. Today about half of the country’s married women are employed outside the home. But, unless family members pitch in with food preparation, women are not fully liberated from that housework. Instead, many have become, in a sense, prisoners of the completely cooked convenience meals. It’s easier to pick up a bucket of fried chicken on the way home from work or take the family out for pizzas or burgers than to start opening cans or heating up frozen dinners after a long , hard day. Also, the rising divorce rate means that there are more single working parents with children to feed. And many young adults and elderly people, as well as unmarried and divorced mature people, live alone rather than as part of a family unit and don’t want to bother cooking for one.
Fast food is appealing because it is fast, it doesn’t require any dressing up, it offers a “fun” break in the daily outline, and the outlay of money seems small. It can be eaten in the car--- sometimes picked up at a drive-in window without even getting out---or on the run. Even if it is brought home to eat, there will never be any dirty dishes to wash because of the handy disposable (一次性的) wrappings. Children, especially, love fast food because it’s finger food, no struggling with knives and forks, no annoying instructions from adults about table manner.
小題1:Americans enjoy fast food mainly because __________.
A．it can be eaten in the car
B．it is much more tasty than home-made food
C．one only uses his fingers while eating it
D．it is time-saving and convenient
小題2:It can be inferred that children __________.
A．want to have more freedom at table
B．never wash dishes after each meal
C．a(chǎn)re good at using forks and knives while eating
D．take eating time as a fun break
小題3: Many Americans are eating out and not cooking at home partially because __________.
A．they want to make a change after eating the same food for years at home
B．the food made outside home tastes better than food cooked at home
C．many of them live alone and don’t like taking trouble to cook
D．American women refuse to cook at home due to women’s liberation movement
小題4:According to the text, a drive-in window is a __________.
A．car window from which you can see the driver
B．window in the restaurant from which you get your takeout in the car
C．place where you check the mechanic condition of your car
D．place where you return the used plates after eating

A “blogger” is a person who writes on an Internet computer Web site called a “blog”. The word “blog” is a short way of saying web log, or personal Web site. Anyone can start a blog, and they can write about anything they like.
There are millions of blogs on the Internet today. They provide news, information and ideas to many people who read them. They contain links to other Web sites. And they provide a place for people to write their ideas and react to the ideas of others.
A research company called Peruse has studied more than 3,000 Web logs. It says that blogs are most popular with teenage girls. They use them to let their friends know what is happening in their lives. The study also says that more than 100,000 bloggers stopped taking part in the activity after a year.
However, some people develop serious blogs to present political and other ideas. For example, the Republican and Democratic parties in the southern state of Kentucky recently started their own blogs. And American companies are beginning to use blogs to advertise their products.
At the same time, some long-standing blogs have ended. Last week, blogging leader Dave Winner closed his free blog service, weblogs.com. He says the site became too costly to continue. He started the blog four years ago, and thousands of people had written on it.
One blog that is still going strong is called Rebecca’s Pocket. It involves much useful information for readers. Rebecca Blood created the Web site in 1999. She wrote about the history of blogs on the site. That article led to a book called “The Weblog Handbook”. It has been translated into four languages so far.
Ms Blood says Rebecca’s Pocket gets about 30,000 visitors a month. She writes about anything and everything----politics, culture and movies. She recently provided medical advice. And she wrote about how to prevent people from stealing money from online bank accounts.
小題1:The text is written mainly to ____
A．introduce an Internet computer Web site called “blog”
B．introduce a way of reading on blogs
C．tell readers about blogs
D．tell readers how to write blogs
小題2:From the text we can learn that blogs cover almost everything except __ _.
A．different ideas
B．medical advice
C．a(chǎn)dvertisements
D．a(chǎn)ccount codes
小題3:According to this passage , which of the following is NOT true?
A．Politicians don’t use blogs at all
B．A lot of bloggers no longer write or read blogs
C．Those who like to use blogs are mostly teenage girls
D．Dave Winer closed his “weblogs.com” because of money shortage
小題4: The reason why Rebecca’s Pocket is still going strong is that____  
A．it was created by a woman
B．it provides plenty of useful information and advice
C．it is about the history of books
D．it has editions in at least four different languages

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 （有回復(fù)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 （傳感器） 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．
小題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．
小題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．
小題3:To design the Zeo device, the three graduate students ____．
A．spent much time and moneyB．were widely supported by scientists
C．worked by themselves all the timeD．a(chǎn)ttracted many investors
小題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．

In the last few years the Internet has become a widespread phenomenon(現(xiàn)象) around the world. People have started to use the computers just like they used to watch TV. Whenever we get hungry, we simply order a pizza through the Internet and while we are waiting for the food, we can send an important business e-mail concerning some sales for tomorrow.

I had this exchange with my 6-year-old last week．
Him: Mom, we have to start buying Danimals．
Me: Why?
Him: So, I can bring it to |school for lunch．It's yogurt ．
Me: Why do you want it so badly?
Him: Because Danimals i|s giving away five fantastic Caribbean vacations．
I had to explain that there was little chance that he would win a vacation．It's a strategy used to encourage kids to beg for artificially-colored （人工著色的） yogurt that costs a lot．
Marketing follows my kids —and yours—wherever they go ．It comes via TV commercials． Store displays and websites are also constantly selling at our kids ．But the most powerful means in kids" lives is the presence of licensed characters on every product imaginable．
Children can begin their day in character clothing．There's even character -themed wall paint available．A breakfast in a character bowl can be followed by a character toothbrush and character toothpaste（牙膏）, character soap and shampoo, and a character wash cloth and towel ．Then, they can put on character clothing and character shoes．Check that, character clock on the wall: Is it time for characier-shaped fruit snacks yet?
Surround kids with enough of the characters and they'll come to believe they need them．Most of us, of course, don't buy all those items．But say no to four products out of five and your home can still get filled with these tiny items encouraging brand loyalty （品牌忠誠(chéng)）
At this time of year, parents buy licensed school supplies．With so much marketing around us, it can be tough to stop the tide．
"One thing that helps parents'is that they can talk to other parents about, this kind of thing," Linn suggested ．"If you decide you want to buck this, it helps to find other people who will do the same thing ．That way, if your child says．"Everyone's doing it," you can really have a sense of whether everyone is．" |
小題1:From the dialogue between the author and the son, we can infer that ____-
A．the son likes drinking yogurt a lot．
B．buying Danimals may win a free tour
