Scott Langteau has this message for kids:spend less time playing video games.
It’s a message that many a mom and dad have tried to impress upon many a youngster (and some not­so­youngsters) who spend perhaps a bit too much time with game controllers in hand.
But the 40­year­old Langteau isn’t a parent.He’s a veteran (老手) of the video game industry—one who played producer on three “Medal of Honor” games and cofounded his own game development company.
Langteau has just published a children’s books called Sofa Boy,which tells the story of a kid who spends too much time sitting on the couch with controller clutched in hand and the rather terrible consequences that follow.
It’s a fairy tale plucked straight from Langteau’s own experiences as a lad with a fondness for video games and his own bouts with a bit of game addiction.But first,Langteau would like to make one thing clear,“I’m not saying that you shouldn’t play video games.I think video games are great.I think they do great things for kids.”Instead,Langteau says his book is all about a little something called moderation (克制).
“It’s about being well rounded,” he says.“Just like with anything else,we all need to make sure that there’s a variety in what we do.”
Video gamers can be rather bad­tempered when it comes to accepting criticism about their favorite entertainment.And understandably so.After all,most people who go around talking about the dangers of playing video games tend to be outsiders—people who don’t play video games and certainly don’t understand that they can be a valuable and healthy form of entertainment.
But Langteau and Sofa Boy seem to be in a  unique position to deliver a message of gaming moderation that the young game masses might actually listen to.After all,this is a man who understands what it means to be a kid with a passion for games.His early experience has taught him a lesson.

Scientists in Israel have discovered a new way to test for water pollution by “listening” to what the plants growing in water have to say.
By shining a laser beam (激光束) on the tiny pieces of algae floating in the water,the researchers said they hear sound waves that tell them the type and amount of contamination (致污物) in the water.
“It is a red light,telling us that something is beginning to go wrong with the quality of water,” said Zvy Dubinsky,an aquatic biologist at Israel’s Bar Ilan University.“Algae is the first thing to be affected by a change in water quality.”“The secret,” he said,“is to measure the rate of photosynthesis (光合作用) in the algae,meaning the plant’s ability to transform light into energy.” During photosynthesis,plants also release oxygen into the air.
Dubinsky’s technique is easy to perform because of the over­abundance of algae in the planet’s water.Most of the oxygen in the atmosphere comes from algae.A prototype tester that occupies about one square meter of a laboratory desktop,shoots a laser beam at water samples to stimulate photosynthesis in the algae.But not all of the laser’s heat is used.Depending on the condition of the algae and the rate of photosynthesis,some of the heat is shot back into the water,creating sound waves,Dubinsky said.With a special underwater microphone,researchers are able to analyze the strength of the sound waves and determine the health of the algae and the condition of the surrounding water.
“Algae suffering from lead poisoning,like waste discharged from battery and paint manufacturing plants,will produce a different sound than those suffering from lack of iron or exposure to other toxins,” said researcher Yulia Pinchasov.She said that testing algae photosynthesis can determine water quality more accurately and easily than labor­intensive methods now used like chemical and radioactive carbon testing.
小題1:The underlined word “algae” in Paragraph 2 probably refers to a kind of________.
A.instrumentB.plant
C.woodD.pollutant
小題2:Why is the algae tested?
A.Because it floats on the water.
B.Because it can have photosynthesis.
C.Because it is the first to be polluted.
D.Because it can produce different sounds.
小題3:We can infer from the passage that________.
A.algae can produce a loud sound when polluted
B.algae can die easily from pollution
C.photosynthesis of the algae can only be caused by sunlight
D.photosynthesis of the algae is related to water quality
小題4:What would be the best title for the passage?
A.Scientists Listen to Plants to Find Water Pollution
B.A Prototype Tester Is Used to Determine Water Pollution
C.The Importance of Photosynthesis of the Algae
D.The Problem of Chemical and Radioactive Carbon Testing

LONDON—Here’s a new warning from health experts:Sitting is deadly.
Scientists are increasingly warning that sitting for long periods—even if you also exercise regularly—could be bad for your health.And it doesn’t matter where the sitting takes place—at the office,at school,in the car or before a computer or TV—just the overall number of hours it occurs.Several studies suggest people who spend most of their days sitting are more likely to be fat,have a heart attack or even die.
In an editorial published this week in the British Journal of Sports Medicine,Elin Ekblom­Bak of the Swedish School of Sport and Health Sciences suggested that authorities rethink how they define physical activity to highlight the dangers of sitting.
While health officials have issued guidelines recommending minimum amounts of physical activity,they haven’t suggested people try to limit how much time they spend in a seated position.
“After four hours of sitting,the body starts to send harmful signals,”said Ekblom­Bak.She explained that genes regulating(調節) the amount of glucose(葡萄糖) and fat in the body start to shut down.
Even for people who exercise,spending long periods of time sitting at a desk is still harmful.Tim Armstrong,a physical activity expert at the World Health Organization,said people who exercise every day—but still spend a lot of time sitting—might get more benefit if that exercise was spread across the day,rather than in a single bout(一回).
Still,in a study published in 2009 that tracked more than 17,000 Canadians for about a dozen years,researchers found people who sat more had a higher death risk,whether or not they exercised.
“We don’t have enough evidence yet to say how much sitting is bad,” said Peter Katzmarzyk of the Pennington Biomedical Research Center in Baton Rouge,who led the Canadian study.“But it seems the more you can get up and interrupt this sedentary behavior,the better.”
Figures from a U.S. survey in 2003­2004 found Americans spend more than half their time sitting,from working at their desks to sitting in cars.
Experts said more research is needed to figure out just how much sitting is dangerous,and what might be possible to offset those effects.
“People should keep exercising because that has a lot of benefits,” Ekblom­Bak said.“But when they’re in the office,they should try to interrupt sitting as often as possible,” she said.
小題1:What is the best title for the text?
A.Not Sitting Too Much While Working
B.How to Avoid Sitting Too Much
C.Sitting Too Much Could Be Deadly
D.More and More People Sit Too Much
小題2:According to the research,________.
A.the more time you spend in exercising in a single bout(一回),the healthier you will be
B.those who often sit too much are sure to grow fat or suffer from a heart attack
C.regular exercise is effective to get rid of the side effects of sitting too much
D.you had better not sit for more than four hours in a single bout
小題3:How does the danger of sitting too much affect the human body?
A.It results in a higher death risk.
B.It increases glucose and fat in the body.
C.It makes a person unable to exercise long enough in a day.
D.It causes the gene to fail to balance the glucose and fat in the body.
小題4:The underlined word “offset” in Paragraph 10 most probably means “________”.

How far would you be willing to go to satisfy your need to know?Far enough to find out your possibility of dying from a terrible disease?These days that’s more than an academic question,as Tracy Smith reports in our Cover Story.
There are now more than a thousand genetic(基因的) tests,for everything from baldness to breast cancer,and the list is growing.Question is,do you really want to know what might eventually kill you?For instance,Nobel Prize­winning scientist James Watson,one of the first people to map their entire genetic makeup,is said to have asked not to be told if he were at a higher risk for Alzheimer’s(老年癡呆癥).
“If I tell you that you have an increased risk of getting a terrible disease,that could weigh on your mind and make you anxious,through which you see the rest of your life as you wait for that disease to hit you.It could really mess you up.” said Dr.Robert Green,a Harvard geneticist.
“Every ache and pain,” Smith suggested,could be understood as “the beginning of the end.”“That’s right.If you ever worried you were at risk for Alzheimer’s disease,then every time you can’t find your car in the parking lot,you think the disease has started.”
Dr.Green has been thinking about this issue for years.He led a study of people who wanted to know if they were at a higher genetic risk for Alzheimer’s.It was thought that people who got bad news would,for lack of a better medical term,freak_out.But Green and his team found that there was “no significant difference” between how people handled good news and possibly the worst news of their lives.In fact,most people think they can handle it.People who ask for the information usually can handle the information,good or bad,said Green.
小題1:The first paragraph is meant to________.
A.ask some questions
B.introduce the topic
C.satisfy readers’ curiosity
D.describe an academic fact
小題2:Which of the following is TRUE of James Watson?
A.He is strongly in favor of the present genetic tests.
B.He is more likely to suffer from Alzheimer’s disease.
C.He believes genetic mapping can help cure any disease.
D.He doesn’t want to know his chance of getting a disease.
小題3:According to Paragraphs 3 and 4,if a person is at a higher genetic risk,it is________.
A.advisable not to let him know
B.impossible to hide his disease
C.better to inform him immediately
D.necessary to remove his anxiety
小題4:The underlined part “freak out” in Paragraph 5 is closest in meaning to “________”.
A.break downB.drop out
C.leave offD.turn away

Many of our favorite travel destinations are in danger of being changed badly by increased temperatures and rising seas. The following are some of the places that may be in danger and some that are already experiencing the effects of global warming.
The Everglades, Florida: Perhaps no region of the country is as unprotected to climate change as Florida. Even a slight increase in temperature and water level could devastate popular destinations like the Everglades, Miami Beach and the Keys.
Australia’s Great Barrier Reef: One of the most impressive natural habitats in the world, the Great Barrier Reef could be killed by increased water temperatures and the resulting coral bleaching (漂白法). Australia is particularly easily damaged by global warming because of its large number of fragile (脆弱的) ecosystems, uncertain water sources and a large group of people gathering on the coast.
Dalian, China: Fast-growing China, shown here during a heat wave last year, is opening about one coal factory every day this year. Along with the U.S., China is one of the world's leading contributors to the greenhouse gases , which can lead to the increase in the Earth's temperature.
Venice, Italy: No stranger to flooding, Venice has invested $4.5 billion in a floodgate system that is due to open in 2012. But the frequent changing ocean levels have made people question the floodgates' ability to hold out the rising waters.
London, England: Designed to protect London from storms and extremely high tides, the Thames Barrier was opened in 1984. Some analysts fear that rising oceans will create conditions beyond the capabilities the barrier was designed to meet.
小題1:The word “devastate” in paragraph 2 means “_____________”.
A.protectB.destroyC.swallowD.enlarge
小題2:What can endanger Great Barrier Reef directly?
A.Fragile ecosystem
B.Uncertain water sources.
C.The large group of people.
D.Increased water temperatures and the coral bleaching
小題3:The underlined sentence means “____________”.
A.flooding is common in Venice
B.everyone is familiar with flooding
C.it is strange for Venice to experience flooding

When 18th-century scientists first came across Australia’s platypus(鴨嘴獸), they thought it was a trick. It is not surprising that the platypus made people confused. This funny-looking animal has feet and is a kind of warm-blooded mammal.
While other mammals usually keep their blood at around 37 degrees, the platypus has a lower body temperature of 32 degrees. As to its appearance, the platypus’mouth is not really like ducks’at all; its mouth actually looks a bit soft. The platypus closes its eyes when swimming. It uses its mouth to pick up outside information made by the creatures underwater.
Strangest of all, the platypus is a mammal that can lay eggs. And there is only one other kind of mammal that can lay eggs, the echidna (針鼴鼠) of Australia. Both the platy-pus and the echidna lay soft-shelled eggs, and both feed their young with their own milk that comes out of their skin. These animals also walk in a way that is similar to crocodiles(鱷魚), with legs on the sides of their bodies rather than under them.
Though pretty, in a special way, the platypus is actually one of the few mammals that are poisonous. A male platypus has knife-like bones on its back legs which have enough poison to kill a dog.
The platypus has the honor of being one of the oldest mammals in the world. Until the early 20th century, it was hunted for its fur, but the situation has changed. Although the platypus is easily affected by pollution, it is not under any immediate threat.
小題1: What can we learn about the platypus according to the text?
A.It has a lower body temperature than other mammals.
B.It only closes its eyes when underwater.
C.It’s the only poisonous mammal in the world.
D.It feeds its young on wild animal meat.
小題2:Which of the following is NOT used as a comparison with the platypus in the text?
A.The crocodile.B.The echidna.C.The duck.D.The dog.
小題3:The following characteristics of the platypus have been described in the text EXCEPT ________.
A.its natural enemyB.its appearance
C.its walking poseD.its daily diet
小題4:We can infer from the last paragraph that the platypus _______.
A.is hunted for its meatB.is in danger of extinction
C.is endangered by air pollutionD.is well-protected now
小題5:Which of the following would be the best title for this text?
A.Platypus, a Trick?
B.Platypus, the Only Warm-Blooded Mammal
C.The Characteristics of Platypus
D.The Strange Mammal —Platypus。

Why do human beings still risk their lives under ground and doing one of the dirtiest and most dangerous jobs in the world? It is an increasingly urgent question, given the recent mining accidents in Sago, W. Va and Huntington, Utah. A small group of engineers and robotics experts look forward to a day in the not-too-distant future when robots and other technology do most of the dangerous mining work. 
Robotic technology, in particular, holds much promise, McAteer says, especially when it comes to mapping mines and rescuing trapped miners --- the special operations of the mining industry.
One of the first mining robots was developed five years ago at Carnegie Mellon University’s Robotics Institute. It was called Groundhog. It used lasers(激光器) to “see” in dark tunnels and map abandoned mines—some of the most dangerous work in the business. 
The latest design is called Cave Crawler. It’s a bit smaller than Groundhog,and even more advanced. It can take photos and videos and has more sensors that can detect the presence of dangerous gases. Incredibly,the robot has a real sense of logic. If it comes across an obstacle it gets momentarily confused. It has to think about what to do and where to go next. Sometimes it throws a fit just like a real person. 
The greatest problem, though, is cost. The money of the earliest research project was provided by the government, but that money had dried up, and it’s not clear where future money will come from. Partly for that reason, and partly because of advances in safety, mining is not nearly as dangerous as it was in the past. Since 1990, fatalities(致命性) have declined by 67% and injuries by 51% , according to the National Mining Association.
Some experts predict that robots in mines will serve much of the same function that they do in the automotive industry. The robots do the most boring and dangerous jobs,but won’t get rid of the need for human workers.
小題1:The latest robot is more advanced than Groundhog, mainly because ____.
A.it can map abandoned mines
B.it can see in the dark tunnels
C.it’s smaller than Groundhog
D.it has a real sense of logic
小題2:The underlined phrase “throws a fit” in paragraph 4 probably means“______”
A.gets angryB.gets sick
C.becomes hungryD.becomes cheerful
小題3:We can infer from the last paragraph that _____ .
A.robots in mines will serve much in the automotive industry
B.there will be no need for human workers in mines
C.the mine robots will have a very bright future
D.robots in mines only do some simple jobs now
小題4:We can infer from the text that ______.
A.the mining robots do most of the mining work at present
B.groundhog can discover the presence of dangerous gases
C.experts are trying to make robots help miners with dangerous work
D.robots cannot do dangerous work in dark areas
小題5:What can be the best title for the text?
A.Mining Accidents in America
B.Robots in Mines
C.Cave crawler, the Latest Robot
D.The Future of Robots

October 15th is the Global Handwashing Day. Activities are planned in more than 20 countries to get millions of people in the developing world to wash their hands with soap. For example, donors(捐贈者) will give 150,000 bars of soap to schools in Ethiopia.
Experts say people around the world wash their hands every day, but very few use soap at so-called important moments. These include after using the toilet, after cleaning a baby and before touching food.
Global Handwashing Day is the idea of the Public-Private Partnership for Handwashing with Soap. Partners include the United Nations Children’s Fund, American government agencies, the World Bank and soap makers Unlever and Procter and Gamble. The organizers say all soaps are equally effective at removing disease-causing germ(細菌). They say the correct way to wash is to wet your hands with a small amount of water and cover them with soap. Rub(揉搓) it into all areas, including under the fingernails(指甲). Rub for at least twenty seconds. Then rinse well under running water. Finally, dry your hands with a clean cloth or wave them in the air.
The Partnership for Handwashing says soap is important because it increases the time that people spend in washing hands. Soap also helps to break up the dirt that holds most of the germs. And it usually leaves a pleasant smell. The Partnership for Handwashing also says washing with soap before eating or after using the toilet could save more lives than any vaccine(疫苗)or medicine. Hand washing could also prevent the spread of other diseases. When people get germs on their hands, they can infect(感染)themselves by touching their eyes, noses or mouths. Then they can infect others.
小題1:What’s the best title for this passage?
A.Say no to washing hands in the wrong way.
B.Find out why washing hands carefully is so important.
C.Hand washing: so important----it gets a day of its own.
D.Want to live a longer life?-wash your hands.
小題2:The word “rinse” in Paragraph 3 probably means ______.
A.to dry your handsB.to wash away the soap
C.to rub your hands carefullyD.to clean your fingers
小題3:The last paragraph mainly tells us ______.
A.how to wash your hands correctly
B.why washing hand with soap is so important
C.the dangers of washing hands without soap
D.when we should especially wash our hands with soap
小題4:In which part of newspaper would you most probably read this passage?
A.Medical care B.Public service C.Health reportD.Advertisement
