Social networking websites are causing alarming changes in the brains of young users, a famous scientist has warned．Sites such as Facebook, Twitter and Bebo are said to shorten attention spans （幅度）, encourage instant satisfaction and make children more self-centered．
Warnings from neuroscientist （神經(jīng)系統(tǒng)科學(xué)家） Susan Greenfield will disturb the millions whose social lives depend on surfing their favorite websites each day．But they will strike a chord （弦） with parents and teachers who complain that many teenagers lack the ability to communicate or concentrate away from their screens．
More than 150 million use Facebook to keep in touch with friends, share photographs and videos and post regular updates of their movements and thoughts．A further six million have signed up to Twitter, the "micro-blogging" service that lets users exchange text messages about themselves．But while the sites are popular and extremely profitable, a growing number of psychologists and neuroscientists believe they may be doing more harm than good．
Baroness Tarot, an Oxford University neuroscientist believes repeated exposure could rewire the brain．Computer games and fast-paced TV shows were also a factor, she said．"My fear is that these technologies are weakening the brain to the state of small children who are attracted by buzzing noises and bright lights, who have a small attention span and live for the moment．" "I often wonder whether real conversation in real time may eventually give way to these easier and faster screen dialogues, in much the same way as killing and butchering an animal to eat has been replaced by the convenience of packages on the supermarket shelf," she said．
Psychologists have also argued that digital technology is changing the way we think．They point out that students no longer need to plan their term papers before starting to write—thanks to word processors they can edit as they go along．
A study by the Broadcaster Audience Board found teenagers now spend seven and a half hours a day in front of a screen．Educational psychologist Jane Healy believes children should be kept away from computer games until they are seven．Most games only excite the "flight or fight" areas of the brain, rather than the areas responsible reasoning．
Sue Palmer, author of Toxic Childhood, said: "We are seeing children's brain development damaged because they don't engage in the activity they have engaged in for thousands of years．I'm not against technology and computers．But before they start social networking, they need to learn to make real relationships with people．"

閱讀下面的短文，并根據(jù)短文后的要求答題（請(qǐng)注意問(wèn)題后的字?jǐn)?shù)要求）。
[1] I was walking in the park with a friend recently, and his cell phone rang, interrupting our conversation. There we were, walking and talking on a beautiful sunny day. But I became invisible, absent from the conversation.
[2] The telephone used to connect you to the absent. Now it makes people sitting next to you feel absent. Recently I was in a car with three friends. The driver told us to be quiet because he could not hear the person on the other end of his cell phone. There we were, four friends going down the highway, unable to talk to one another because of a tool designed to make communication easier.
[3]Why is it that the more connected we get, ________________________ ? Every advance in communications technology is a hurt to the closeness of human interaction (互動(dòng)). With e-mail and instant messaging over the Internet, we can now communicate without seeing or talking to one another. With voice mail, you can conduct entire conversations without ever reaching anyone.
[4] More and more, l find myself hiding behind e-mail to do a job meant for conversation. Or being relieved that voice mail picked up because I didn’t really have time to talk. The industry devoted to helping me keep in touch is making me lonelier.
[5] So I've put myself on technology restriction: no instant messaging with people who live near me, no cell-phoning in the presence of friends, no letting the voice mail pick up when I' m home.

★The regular use of text messages and e-mails can lower the IQ more than twice as much as smoking marijuana(大麻). Psychologists say that sending/receiving messages or looking through the many menu options your mobile phone has, lowers a person’s IQ by almost 10 points. British researchers have named this situation “infomania”. Instead of fixed on what they are doing, people’s minds are constantly focused on reacting to the technology surrounding them. This means they don’t pay full attention to the work they are paid to do. The report also added that the brain can not do so many things at once. If you try to do too many things, mistakes begin to occur. And while modern technology can have huge benefits, too much use can be damaging not only to a person’s mind, but to their social life.
★The more televisions 4-year-old children watch, the more likely they are to become bullies later on in school, a newest U.S. study said. At the same time, children whose parents read to them, take them on outings and just generally pay attention to them are less likely to become bullies, said the  report from the University of Washington. Researchers also found gaps in learning and understanding such things as social skills early in life makes it more difficult for children to relate with other children. Watching violence on television leads to aggressive behavior.
★You could soon be able to add your favorite perfume to your e-mails. UK net provider Telewest Broadband is testing a system to let people send e-mails over the Internet with sweet smell. It has developed a kind of hi-tech air freshener that plugs into a PC and sprays a smell linked to the message. Telewest says it could be used by supermarkets to attract people with the smell of fresh bread or by holiday companies seeking to stir up images of sun-kissed beachers.

小題2:.
According to the second part of the text, _____ are less likely to become bullies.
A．children whose parents care about them
B．children whose parents give them more freedom
C．children whose parents direct them over watching TV
D．children whose parents stop them watching TV
小題3:.
The children who watch TV  frequently will not ______.
A．be aggressive
B．be likely to become bullies
C．have difficulty in communicating with other children
D．understand socially skills as easily
小題4:.

With the development of society and economy, animals and their habitats are getting pushed aside as households decrease in size and increase in number.
Small numbers of people per household on average use more energy and goods per person. Greater numbers of households require more natural resources for construction. The possible result of this problem may be insufficient natural resources to meet consumer demand without endangering habitats important to biodiversity.
Personal freedom and social choice may come at huge environmental cost. Direct costs include visible damage to animal habitats and plant life. Indirect costs include the release of more greenhouse gases.
The effects of such “personal freedom and social choice” have already surfaced in south-west China’s Wolong Nature Reserve. In Wolong, they found that a reduced average household size was directly tied to an increase in homes, and thus an increase in the amount of firewood consumed for cooking and heating. The rise in wood fuel use has contributed to disappearance of forests and to the loss of habitats for giant pandas. 
Curious about whether other parts of the world were experiencing similar phenomena, they got the support of a team of researchers including Stanford’s Paul Ehrlich, well-known for his population studies, to find out the household dynamics in 141 countries between 1985 and 2000. Their study proved that the difficult choice of Wolong is part of a global trend.
In the 76 countries considered biodiversity “hotspots”, such as the United States, Brazil, Australia, and Kenya, the number of households grew by 3.1% every year, while the population increased just 1.8%. Meanwhile, the number of people per home dropped from 4.7 to 4.0. The decline in household size has resulted in 155 million additional households in hotspot countries, almost always limiting biodiversity.
In the 10 non-hotspot countries — those without high-density areas of animal and plant species — similar results were found, though on a lesser scale. Even in countries experiencing population decline, such as New Zealand, the number of households still increased because of a reduction in household size.
小題1:What does the underlined word “insufficient” mean?
A．Plenty of.B．Not enough.C．Abundant.D．Little.
小題2:It can be learned from the passage that China’s Wolong Nature Reserve_____
A．is facing the same threat as many other parts of the world
B．sets a good example in protecting animals
C．is a place where giant pandas and their habitats are not affected
D．is a place where animals and their habitats are seriously damaged
小題3:Which of the following is best supported by the last two paragraphs?
A．Biodiversity is better kept in countries with smaller populations.
B．Biodiversity is better kept in hotspot countries.
C．The threat to nature from reduction in household size is a worldwide problem.
D．Both hotspot countries and non-hotspot countries face the threat of the same scale.
小題4: What does the passage mainly talk about?
A．Reduced household size leads to an increase in household number.
B．Modern homes consume more natural resources.
C．How to meet consumer demand without endangering animals and their habitats.
D．Reduction in household size as well as increase in household number threatens nature.

An Australian company, Smart Car Technologies, has developed a system that lets drivers know when they’re speeding. When the technology becomes commercially available, it could help lead-footed drivers avoid tickets and also save lives. The company that developed the product hopes to convince Australian government agencies to put the technology into use in their automobile fleets.
The product, called Speed Alert, links real-time location data and speed obtained with the help of GPS to a database of posted speed limits stored in a driver’s PDA or programmable mobile phone. The setup of the product does not need to be hooked up to a car’s speedometer. In fact, it is entirely portable. It will also work with newer phones and PDAs that have built-in GPS receivers. If a driver exceeds the speed limit, the speed is shown and an alert sounds.
Michael Paine, an Australian vehicle design engineer and traffic safety consultant, was hired to analyze the product. He told Live Science that his colleagues in the road safety field are “very enthusiastic” about what they’re now calling “intelligent speed alert.” Other research, according to Paine, shows that 40 percent of all traffic deaths involve speeding. There is also a potentially controversial future use: “Since the system is so portable, it would be easy to make it a requirement for teenage drivers to always use a speed alert device when driving,” Paine said. “The system even has the capability to record speeding violations, so parents can monitor their teenage drivers.”
The product will soon go on sale in Sydney.
小題1: What’s the purpose of the new product?
A．To inform us of the new car system.B．To introduce some improvement in cars.
C．To limit certain drivers to safe driving.D．To popularize the built-in car system.
小題2:The second paragraph mainly talks about        .
A．the project of the built-in productB．why the system becomes popular
C．the functions of GPS in carsD．how the product is programmed
小題3:Which of the following is true of Speed Alert according to Michael Paine?
A．Most of the traffic deaths can be avoided.B．Speeding violations can be easily found out.
C．The system will excite some teenage drivers. D．The product will not be available for adults.
小題4:What can be the best title of the passage?
A．Speed Alert and Its Future Use.B．Progress in Car-making Science.
C．Warning for Adventurous Drivers.D．New In-Car Device against Speeding.

Gaudi Nanda sees a wearable computer as a handbag --- one that's built out of four-inch squares and triangles of fiber, with tiny computer chips embedded (嵌于) in it. It looks, feels and weighs like your typical leather purse.
That's where the similarities end: this bag can wirelessly keep track of your belongings and remind you, just as you're about to leave the house, to take your wallet. It can review the weather report and suggest that you take an umbrella. This purse can even upload your favorite songs onto your scarf.
Surely, a computing purse and scarf set may seem like the stuff of science fiction. But these devices, part of next generation of wearable computers, could become commonplace within a few years. Dupont created new super strong fibers that can conduct electricity and can be woven into ordinary-looking clothes. And the chipmaker developed chip packaging allowing wearable computers to be washed, even in the heavy-duty (耐磨損的) cycle.
As a result, these new wearable devices are different from the heavy and downright silly versions of the recent past, which often required users to be wrapped in wires and type on their stomachs. Unlike their predecessors, these new wearable computers also make economic sense. When her bag becomes commercially available in two to three years, Nanda expects it will cost around $ 150, which is the price of an average leather purse.
Here's how the bag works: You place a special radio-signal-transmitting chip onto your wallet. A similar radio in your purse picks up the signal and notifies you that you've forgotten to take your wallet. In turn, sensors on your purse's handles will notify the computer that you've picked up the purse and are ready to go.
Already, these new kinds of wearable devices are being adopted for use in markets like auto repair, emergency services, medical monitoring - and even, increasingly, for consumers at large. Indeed, more people will want to cross that bridge in the coming years - making for a booming market for wearable computers that don't look like something out of science fiction.
小題1: According to the passage, the new wearable computers _______.
A．require users to operate on the stomach
B．pick up the signals through wires and chips
C．a(chǎn)re being applied in some different areas now
D．a(chǎn)re smarter but more expensive than the old ones
小題2:What does the underlined sentence in the last paragraph mean?
A．The new wearable computers have become fashionable.
B．People would like to learn more about the new computers.
C．New wearable computers promise to sell well in the future.
D．The idea of the purse-like computers comes from science fiction.
小題3:The purpose of the passage is to ________
A．introduce a new kind of computer
B．explain the functions of computers
C．compare different types of computers
D．show how high technology affects our life

On the first day of class, a graduate student from Xi’an Jiaotong University reminded me that, especially in China, “There are always two sides of a coin.” Experiencing China’s May 12 earthquake while living in Xi’an, Shanxi Province just north of the earthquake’s epicenter (地震的震中) in Sichuan with our two daughters, we have indeed seen both sides of what is beginning to be called China’s 5·12 disaster coin.
On television, in newspapers and through the Internet, we learned about the extent (巨大，重要性) of the destruction, and the statistics were horrific – over 69,000 confirmed (確認(rèn)) dead, some 18,000 missing and more than 374,000 injured.
When we turn off the television and discuss what we as a family have learned from the events of the last several weeks, we find ourselves marveling (覺(jué)得驚奇) at how the Chinese are confidently but quietly dealing with this unprecedented tragedy – a disaster that continues with every aftershocks, mudslide and potential flood.
It seems like every school, organization and business is raising money for Sichuan, and young people all over the country are out in the streets looking for donations or giving blood at the many mobile blood vans that are out in full force.
Those who cannot give, like the 75-year-old woman from Sichuan, are volunteering or giving in other ways. An impressive example is the Sichuan policewoman with a newborn child who was nursing many infants whose mothers were killed in the quake.
The national concern over the fate of affected children has been moving. On May 22, there were 1697 orphans, but on June 24, the number dropped to 558; and rest assured, there are more people willing to adopt than there are orphans from Sichuan.
So, while no country or person ever welcomes tragedy, especially something of this magnitude (程度), the earthquake has taught us a great deal about China’s true character and its people’s resilience (韌性). It has also reminded us that the other side of even a dark coin may hold the promise of a brighter future,
(The author is an American Professor of International Relations at Xi’an Jiaotong University.)
小題1:

A．a(chǎn) dark side and a bright one of a coin
B．the unprecedented tragedy and China’s true character
C．the dead and the victims in the earthquake
D．the destruction and the donations
