In the near future,we may be using our eyes to operate our smart-phones and tablets,even when it comes to playing popular games like Fruit Ninja.
The Gaze Group has been developing eye-controlled computer technology for nearly 20 years.But those devices have been firstly designed to help those with disabilities,and are very expensive.
“After a while,we figured out that probably the best way is to go for a mass-market way,” says Gaze’s Sune Alstrup Johansen.“where everybody would have this available."
Johansen and some of his colleagues have formed a new company,the Eye Tribe,which is hoping to develop the technology on a mass commercial level.
The technology works with the help of the computing device toward the user’s face. After making sure of the user’s eye movements,the technology is then able to easily find where a person’s eyes are moving,and then allow the eyes to control a cursor(光标).
“Our software can then determine the location of the eyes and know where you’re looking on the screen to make sure what you’re looking at,“reads an explanation on the Eye Tribe site.
There has been a gradual change toward hands-free technology in recent years, particularly in the gaming world.Recently Xbox released the Kinect device,which lets users control their Xbox and play certain games using only their hands,legs and voices. But still,most of these devices have been more of a gimmick than a practical way to use one’s hands to control a mobile device.Johansen said a replaceable filter(滤光器)would be a cheap,convenient way for most consumers.
And even as companies like The Eye Tribe work to create such a product for the average user, making the eye-controlled technology more accessible and less expensive will have similar benefits for physically disabled users.

New research shows that overweight or even mildly obese people have a lower risk of early death than people considered to be normal weight.
Researchers examined the results of 97 studies. Most of the studies were less than 10 years old. They included almost three million adults from around the world, including the United States, Canada, China, Taiwan, Brazil, India and Mexico.
The researchers at the National Center for Health Statistics found that people who are considered overweight or slightly obese were five to six percent less likely to die from all causes than people of normal weight. People with higher obesity ratings, however, had almost a 30 percent greater risk of death compared to normal-weight individuals.
Katherine Flegal was the lead author of the study. She says she was not surprised that overweight people would not have a higher risk of death.
“Because we’d actually already read a lot of this literature and realized it was likely that mortality rates (死亡率) for overweight would be at least not higher than normal weight. I guess I was a little bit surprised that it was definitely lower. And I was also surprised that the lower rates of obesity also didn’t seem to differ from normal weight.”
But she says the difference in death rates appears to be small between normal-weight people and those who are overweight or mildly obese.
The study has raised new questions about “body mass index,”(体重指数) or BMI. This is a measurement of body fat as a ratio(比率) of height to weight. In recent years, many public health experts have promoted body mass index as a way to predict the risk of health problems. Bu t a person's BMI can be misleading in some cases.
Steven Heymsfield ,the executive director of the Pennington Biomedical Research Center, says people can be physically fit and in good health, but might weigh more because they are more muscular.
Still, Dr. Heymsfield says people should not think gaining extra weight is OK just because of the new findings. He says being at a healthy weight lowers the risk for heart disease and diabetes(糖尿病).
小题1:According to the new findings, the researchers found that __________ .
A.People with high obesity have a lower risk of early death than people with low obesity
B.People with overweight have a greater risk of early death than people of normal weight.
C.People with mild obesity are less likely to die than people of normal weight.
D.People with obesity live much longer than people of normal weight.
小题2:What does the underlined word “literature” in paragraph 6 mean ?

It’s 8:30, time for John to start work. So he turns on his radio. Then he eats breakfast. As he eats, he reads his e-mail and reviews his to-do list. Then he sits on the sofa and thinks about an article he needs to write ... Wait a minute! Radio? Breakfast? Sofa? What kind of workplace is this? Well, actually it is John’s house, and he is a telecommuter —  he works at home, communicating with the workplace through the Internet.
Like John, millions of people — and their employers — are finding that telecommuting is a great way to work. Telecommuters can follow their own timetables. They work in the comfort of homes, where they can also look after young children or elderly parents. They save time and money by not traveling to work. Their employers save, too, because they need less office space and furniture. Studies show that telecommuters change jobs less often. This saves employers even more money. Telecommuting helps society, too, by reducing pollution and traffic problems.
Jobs that are suited to telecommuting include writing, design work, computer programming and accounting. If a job is related to working with information, a telecommuter can probably do it.
小题1:From the passage we can learn that John does his job           .
A.by telephonB.through the Internet
C.in his officeD.away from home
小题2:One of the advantages of telecommuting is that you can        .
A.work for several employersB.enjoy a lot of traveling
C.get along well with other workersD.work on your own schedule
小题3:Telecommuters change jobs less often, so         .
A.their employers can save money
B.their employers will give them a higher pay
C.they can get more work experience
D.they will have a longer paid holiday
小题4:The underlined phrase “suited to” in the third paragraph probably means “       ”.
A.acceptable forB.bad forC.difficult forD.fit for

The economic growth that many nations in Asia and increasingly Africa have experienced over the past couple of decades has transformed hundreds of millions of lives – almost entirely for the better. But there’s a byproduct to that growth, one that’s evident – or sometimes less than evident – in the smoggy, smelly skies above cities like Beijing, New Delhi and Jakarta. Thanks to new cars and power plants, air pollution is bad and getting worse in much of the world, and it’s taking a major toll (伤亡人数,代价) on global health.
How big? According to a new analysis published in the Lancet, more than 3.2 million people suffered deaths from air pollution in 2010, the largest number on record. That’s up from 800,000 in 2000. And it’s a regional problem: 65% of those deaths occurred in Asia, where the air is choked by diesel soot (内燃发动机烟雾) from cars and trucks, as well as the song from power plants and the dust from endless urban construction. In East Asia and China, 1.2 million people died, as well as another 712,000 in South Asia, including India. For the first time ever, air pollution is on the world’s top – 10 list of killers, and it’s moving up the ranks faster than any other factor.
So how can air pollution be so damaging? It is the very finest soot – so small that it roots deep within the lungs and then enters the bloodstream – that contributes to most of the public – health toll of air pollution including death. Diesel soot, which can also cause cancer, is a major problem because it is concentrated in cities along transportation zones affecting overpopulated areas. It is thought to contribute to half the deaths from air pollution in urban centers. Fro example, 1 in 6 people in the U.S. live near a diesel – pollution hot spot like a rail yard, port terminal or freeway.
We also know that air pollution may be linked to other non – deadly diseases. Fortunately in the U.S. and other developed nations, urban air is for the most part cleaner than it was 30 or 40 years ago, thanks to regulations and new technologies like the catalytic converters (催化式排气净化器) that reduce automobile emissions. Govemments are also pushing to make air cleaner – see the White House’s move last week to further tighten soot standards. It’s not perfect, but we’ve had much more success dealing with air pollution than climate change.
Will developing nations like India eventually catch up? Hopefully – though the problem may get worse before it gets better. The good news is that it doesn’t take a major technological advance to improve urban air. Switching from diesel fuel to unleaded (无铅燃油) helps, as do newer and cleaner cars which are less likely to send out pollutants. Power plants – even ones that burn mineral fuels like coal – can be fitted with pollution – control equipment that, at a price, will greatly reduce smog and other pollutants.
But the best solutions may involve urban design. In the Guardian, John Vidal notes that Delhi now has 200 cars per 1,000 people, far more than much richer Asian cities like Hong Kong and Singapore. Developing cities will almost certainly see an increase in car ownership as residents become wealthier – and that doesn’t have to mean deadly air pollution. Higher incomes should also lead to tougher environmental regulations, which is exactly what happened in the West. We can only hope it happens before the death toll from bad air gets even higher.
小题1:What tends to give rise to the highest death toll according to the passage?
A.The lack of tight environmental protection standards.
B.The increasing numbers of the diesel cars and trucks.
C.The frighteningly high death rate from deadly cancer.
D.The world’s serious air pollution such as soot and dust.
小题2:The “byproduct” (Paragraph 1) most probably refers to     .
A.consequenceB.solutionC.reformD.design
小题3:The basic reason why so many people die from air pollution is that       .
A.the diesel soot is too small to be seen
B.the diesel soot is much too poisonous to breathe
C.the diesel soot roots in lungs and gets into blood
D.the diesel soot can also contribute to deadly cancer
小题4:According to the passage, the writer actually wants to convince the readers that        .
A.the global economic growth is mainly to blame for air pollution and climate change
B.the developing countries are repeating the same mistakes as the developed ones made
C.the ecological situation and air pollution in India are becoming worse and worse
D.the unbeatable air is increasingly becoming a major killer throughout the world
小题5:By describing urban design as “the best solution” in the last paragraph, the writer means that        .
A.the making of tougher environmental regulations alone is of little use
B.more sever regulations should be made to handle air pollution
C.the urban construction in western developed countries is the best choice
D.the pace of development has to be slowed down to reduce air pollution

Antidepressant(抗忧郁)drugs such as Prozac were viewed in the early 1900's as wonder pills that would remove depressive blues for good. But in the past five years, growing scientific evidence has shown these drugs work for only a minority of people. And now a research journal says that these antidepressants can make many patients' depression worse. This alarming suggestion centres on the very chemical that is targeted by antidepressants-serotonin(血清素). Drugs such as Prozac are known as selective serotonin re-uptake inhibitors(or SSRIs). Their aim is to increase the level of this  “feel-good” chemical in the brain.
But the new research, published in the journal Frontiers In Evolutionary Psychology, points out that serotonin is like a chemical Swiss Army knife, performing a very wide range of jobs in the brain and body. And when we start changing serotonin levels purposely, it may cause a wide range of unwanted effects. These can include digestive problems and even early deaths in older people, according to the study's lead researcher Paul Andrews. “ We need to be much more cautious about use of these drugs,” says Andrews, an assistant professor of evolutionary psychology at McMaster University in Ontario, Canada.
Previous research has suggested that the drugs provide little benefit for most people with mild depression, and actively help only a few of the most severely depressed. Famous psychologist Irving Kirsch has found that for many patients, SSRIs are no more effective than a placebo pill. A research in 2010 on Danish children found a small, but significant, increase in the risk of heart problems among babies whose mothers had used SSRIs in early pregnancy. The key to understanding these side-effects is serotonin, says Andrews. Serotonin is also the reason why patients can often end up feeling still more depressed after they have finished a course of SSRI drugs. He argues that SSRI antidepressants disturb the brain, leaving the patient an even greater depression than before.
“After long use, when a patient stops taking SSRIs, the brain will lower its levels of serotonin production,” he says, adding that it also changes the way receptors in the brain respond to serotonin, making the brain less sensitive to the chemical. These changes are believed to be temporary, but studies indicate that the effects may continue for up to two years.
Most disturbingly of all, Andrews' review features three recent studies which, he says , show that elderly antidepressant users are more likely to die earlier than non-users, even after taking other important variables into account. One study, published in the British Medical Journal last year, found patients given SSRIs were more than 4 per cent more likely to die in the next year than those not on the drugs.
“Serotonin is an ancient chemical,” says Andrews. “It is regulating many different processes, and when you disturb these things, you can expect that it is going to cause some harm.”
Stafford Lightman, professor of medicine at the University of Bristol, and a leading UK expert in brain chemicals and hormones, says Andrews’ review highlights some important problems, yet it should also be taken with a pinch of salt. “This report is doing the opposite of what drug companies do,” he says. “Drug companies selectively present all the positives in their research, while this search selectively presents all the negatives that can be found. Nevertheless, Andrews' study is useful in that it is always worth pointing out that there is a downside to any medicine. ” Professor Lightman adds that there is still a great deal we don't know about SSRIs-not least what they actually do in our brains.
When it comes to understanding why the drugs work only for a limited part of patients, U.S.  scientists think they might now have the answer. They think that in many depressed patients, it’s not only the lack of feel-good serotonin causing their depression, but also a failure in the area of the brain that produces new cells throughout our lives. This area, the hippocampus, is also responsible for regulating mood and memory. Research suggests that in patients whose hippocampus has lost the ability to produce new cells, SSRIs do not bring any benefit.
小题1:According to paragraph 2, serotonin, like a chemical Swiss Army knife, can             .
A.make many patients' depression worse
B.cause a wide range of unwanted effects
C.affect human body and brain in various ways
D.provide little benefit for most depressed people
小题2:In Stafford Lightman's opinion,                    .
A.drug companies don't know the negative effect of antidepressants
B.Andrews focused on different things from the drug companies
C.scientists have found what SSRIs do in the brain
D.Andrews' research has no medical value
小题3:Which of the following is TRUE about SSRIs?
A.They are used to increase the “feel-good” medical in the brain.
B.They can work even when the hippocampus can't produce new cells.
C.They create a risk of heart problems in pregnant women.
D.They are responsible for controlling mood and memory.
小题4:What is the text mainly about?
A.The aim of drug companies
B.The function of SSRIs
C.The side-effects of antidepressants
D.The cause of depression

Imagine living in a city made of glass. No, this isn’t a fairy tale. If you could grab your diving gear and swim down 650 feet into the Pacific Ocean off the coast of Washington State, you would witness the secret world of glass reefs.
The reef you’d be looking at is made up of glass sponges(海绵). But how can animals be made of glass? Well, glass is formed from a substance called silica. The sponges use the silica found in ocean waters to build glass structures that will give them shape and support. Be careful! Some of the fragile creatures are up to 200 years old.
When sponges die, new ones grow on top of the pile of old ones. Over centuries, a massive and complex reef takes shape. Some sponges look like wrinkled trumpets, while others look like overgrown cauliflower or mushrooms.
Dr. Paul Johnson, who discovered the Washington reef in 2007, also found other surprises such as bubbles of methane(甲烷) gas flowing out of the seafloor nearby. The methane feeds bacteria, and the bacteria feed the glass sponges.
“It’s a new ecosystem we know nothing about,” said Dr. Johnson.
The reef of yellow and orange glass sponges is crowded with crabs, shrimp, starfish, worms, snails, and rockfish. The glass reef is also a nursery for the babies of many of these creatures and was called a “kindergarten” by scientists.
Many animals that live in the reef hang around for a long time, just like the sponges. Rockfish, for example, live for more than 100 years. Scientists are just beginning to study all the species that call the reef home.
The Washington coast isn’t the only place where a living glass reef has been found. The first was discovered in Hecate Strait off the coast of British Columbia in 1991. Scientists all over the world were stunned to see it.
小题1:Which of the following is the best title for the passage?
A.Man-made cities under the seaB.The world under the sea
C.Glass “cities” under the seaD.Creatures under the sea
小题2:It can be learned that the glass reef _______.
A.is made up of a kind of materials called sponges
B.is a work of art made by some American scientists
C.is a new ecosystem people are not familiar with
D.was first discovered off the coast of Washington State
小题3:Which of the following is TRUE according to the passage?
A.The sponges must feel soft.
B.Silica comes from animals’ body fluid.
C.Methane is harmful to glass sponges.
D.Glass sponges depend on the bacteria for a living.
小题4:Why did scientists call the glass reef a “kindergarten”?
A.Because the babies of many sea creatures grow well there.
B.Because thousands of children visit it every year.
C.Because it is crowded with snails and rockfish, etc.
D.Because all the species call the reef home.
小题5:What does the underlined word “stunned” in the last paragraph mean?
A.Greatly surprised.B.Extremely scared.
C.Highly satisfied.D.Very pleased.

The computer keyboard helped kill shorthand---a system of rapid handwriting, and now it's threatening to finish off handwriting as a whole. When handwritten essays were introduced on the SAT exams for the class of 2011, just 15% of the most 1.5 million students wrote their answers in cursive (草写字母).The rest? Block letters.
And those college hopefuls are just the first edge of a wave of US students who no longer get much handwriting instructions in the primary grades, frequently 10 minutes a day or less. As a result, more and more students struggle to read and write cursive.
At Keene Mill Elementary School in Springfield, all their poems and stories are typed. Children in Fairfax County schools are taught keyboarding beginning in kindergarten. Older students who never mastered handwriting say it doesn't affect their grades.
There are those who say the culture is at a crossing, turning from the written word to the typed one. If handwriting becomes a lost form of communication, does it matter?
It was at University of Virginia that researchers recently discovered a previously unknown poem by Robert, written in his unique script. Handwritten documents are more valuable to researchers, historians say, because their authenticity (真实性)can be confirmed. Students also find them more fascinating.
The loss of handwriting also may be a cognitive (认知的)opportunity missed. Several academic studies have found that good handwriting skills at a young age can help children express their thoughts better-a lifelong benefit.
It doesn't take much to teach better handwriting skills. At some schools in Prince George's County, elementary school students use a program called Handwriting Without Tears for 15 minutes a day. They learn the correct formation of manuscript letters through second grade, and cursive letters in third grade.
There are always going to be some kids who struggle with handwriting because of their particular neurological (神经系统的)wiring, learning issues or poor motor skills. Educators often point to this factor in support of keyboarding.
小题1:What is the author concerned about after 2011 SAT exams?
A.Keyboarding.B.Shorthand
C.Handwriting.D.Block letters.
小题2:A poem by Robert mentioned in the passage is used to _________.
A.prove how valuable handwriting is
B.explain what a famous poet he is
C.show how unique his poem is
D.stress how fascinating the documents are
小题3:The example of Handwriting Without Tears helps to argue that_________.
A.the schools are responsible for the loss of handwriting
B.the loss of handwriting is a cognitive opportunity missed
C.it doesn't take much to teach better handwriting skills
D.the culture is turning from the written word to the typed one
小题4: According to the author, when is a perfect time to learn handwriting?
A.Kindergarten.B.Primary school.C.High school.D.College.
小题5:What is the author’s attitude towards this debate?
A.Devotion.B.Encouragement.C.critical.D.Objective.

When someone says “SHARK” most people think of a big, toothy, underwater animal; basically we are imagining a Great White. In fact sharks come in all shapes, sizes and even colors! Follow me please; I’d like to show you a very special small shark commonly known as horn sharks, only found in the coastal waters of north-west North America.
Look at this shark, and you can easily see the horns on it and you will know the reason why it is called the horn shark is that it has the broad, flattened head and two large horn-like spines(脊椎) found behind its eyes and makes it one of the hardiest of all shark species. What makes it unique is that as its enemy attempts to swallow it, the spines on its back will stick into the enemy’s mouth and give a good chance for it to get away.
The horn shark is brown in color with black spots all over its body. The adults can reach up to a length of 4 feet and weigh up to 10 kg. An interesting fact about the horn shark is that it has five gills(鳃). The horn shark is a clumsy swimmer using its flexible pectoral fins(胸鳍)to push itself along the bottom of the ocean. The maximum distance that has ever been recorded for a horn shark to have traveled out from its habitat is 10 miles.
Today, as so little is known about its population off the Californian coast, they have been listed as being “Data Deficient” in the World Conservation Union. The horn shark is being threatened both by water pollution and commercial fishing in the area. Though they are not among those sea creatures hunted primarily for food, but they often get caught as a by-catch in fishing expeditions.
小题1:The horn shark gets its name for______.
A.its small sizeB.its large eyes
C.its two large spinesD.its brown color with spots
小题2:How is paragraph 3 mainly developed?
A.By giving descriptionsB.By following time order
C.By analyzing causesD.By making comparisons
小题3:Which factors contribute to the horn shark’s being on the “Data Deficient” list?
①That people like hunting them for pets       ②That people fish them for fun
③Water pollution off the coast               ④Knowing little about them
A.①②B.②③C.①④D.③④
小题4: According to the passage, all of the following are unique to the horn shark EXCEPT that_____.
A.it doesn’t travel far
B.it is good at swimming
C.its spines can be used to attack the enemy and escape
D.it is only found in the coastal waters of north-west North America
