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 (神经系统科学家) 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way to these easier and faster screen dialogues, in much the same way as killing and butchering an animal to eat has been replaced by the convenience of packages on the supermarket shelf," she said.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."

We like to consider ourselves the superior race, and we are. It’s true that we are getting to know more and more, and we actually live in “the information age”. Our human vanity(虚荣心) makes us believe that we really have to know everything! Surprisingly, we do not have this ability. The question “what is happening in the Bermuda Triangle” is the very proof.
Where is the Bermuda Triangle located? The mysterious triangle is believed to be situated between Florida, Bermuda and Puerto Rico, where too many unusual events have happened.
On December the 5th 1945, five U.S. military planes took off from Florida on a clear day only to disappear over Bermuda. Furthermore, some other disappearances took place; in 1947, an American C54 plane simply disappeared at 100 miles from Bermuda; at 80 miles, a Star Tiger plane disappeared in 1948.
Even Columbus had trouble in Bermuda. Some of his journals were about the strange happenings there: “the waters are changing their colors” and “compasses are going wild”.
Maybe it’s why it is called the Devil’s triangle or the Atlantic cemetery.
Many hypotheses were stated in order to explain the strange events. In spite of these attempts, the mystery of the Bermuda Triangle remains unsolved.
Some people get to say that maybe aliens are involved in it. Other imaginative scientists relate the happenings in Bermuda to Einstein’s theory, saying that the missing ships and planes are translated to another dimension of space and time and taken into another world.
Maybe we will just have to wait to go to Heaven and ask the One who made it. The answer will surely be a satisfying one!
小题1:The writer may probably think that______.
A.humans have to and can know everything strange
B.the missing ships are taken into another world
C.humans can know more in “the information age”
D.God created the mystery of the Bermuda Triangle
小题2: Columbus’ journals told us that in Bermuda _______.
A.an American C54 plane disappeared
B.there were some strange happenings
C.the compasses were lost
D.a cemetery was found
小题3:The underlined word “hypotheses” in the 6th paragraph probably means______.
A.guessesB.reportsC.placesD.stories
小题4:The purpose of the writer is to______.
A.tell some stories about the Bermuda Triangle
B.warn people not to travel to the Bermuda Triangle
C.laugh at man’s vanity to know everything
D.prove man does not have the ability to know all

Are some people born clever and others born stupid? Or is intelligence developed by our environment and our experiences? Strangely enough, the answer to both questions is yes.To some extent our intelligence is given to us at birth, and no amount of special education can make a genius out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings. Thus the limits of a person’s intelligence are fixed at birth, but whether or not he reaches those limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways.
It is easy to show that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be in intelligence. Thus if we take two unrelated people at random (随意地) from the population, it is likely that their degrees of intelligence will be completely different. If on the other hand we take two identical twins, they will very likely be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that integigence depends on birth.
Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is boring. We would soon find differences in intelligence developing, and this indicates (表明) that environment as well as birth plays a part. This conclusion is also suggested by the fact that people who lives in close contact with each other, but who are not related at all, are likely to have similar degrees of intelligence.
小题1:Which of the following best describes the writer’s point in Paragraph One?
A.To some extent, intelligence is given at birth.
B.Intelligence is developed by the environment.
C.Some people are born clever and others born stupid.
D.Intelligence is fixed at birth, but is developed by the environment.
小题2:In the first paragraph,“no amount of special education can make a genius out of a child born with low intelligence” suggests that       .
A.no environment can change the least able into the most able
B.the difference in men’s intelligence depends on the amount of their education
C.if a person is born clever, he is certain to be a genius
D.if a person is born stupid, nothing can change him into an educated person
小题3:The last paragraph mainly shows       .
A.the importance of education
B.the relationship between environment and birth
C.the writer’s final conclusion
D.the relationship between intelligence and environment
小题4:The best title for this passage would be       .
A.Dependence on EducationB.Intelligence
C.SurroundingsD.Effect of Education
小题5:Which statement about the passage is true?
A.All twins have similar degrees of intelligence.
B.A man who is educated in university must make greater achievements than a man who works in a boring factory.
C.Proper education can change one’s intelligence at some degree.
D.Education can’t make a child born with low intelligence cleverer.

阅读下面的短文,并根据短文后的要求答题(请注意问题后的字数要求)。
[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.

There we were, four friends going down the highway, unable to talk to one another because of a tool designed to make communication easier.

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.
