If you are sending a text message, watching TV or listening to the radio, you may stop and give this your full attention. Multi-tasking shrinks(使……萎缩) the brain, research suggests.
A study found that men and women who frequently used several types of technology at the same time had less grey matter in a key part of the brain. University of Sussex researchers said, “Using mobile phones, laptops and other media devices simultaneously could be changing the structure of our brains.”
Worryingly, the part of the brain that shrinks is involved in processing emotion. The finding follows research which has linked multi-tasking with a shortened attention span, depression, anxiety and lower grades at school.
The researchers began by asking 75 healthy men and women how often they divided their attention between different types of technology. This could mean sending a text message while listening to music and checking email, or speaking on the phone while watching TV and surfing the internet. The volunteers were then given brain scans which showed they had less grey matter in a region called the anterior cingulated cortex (ACC) (前扣带皮质). Scientists have proved that brain structure can be changed on exposure to fresh environments and experience.
Other studies have shown that training – such as learning to play magic tricks or taxi drivers’ learning the map of London – can increase grey-matter densities(密度) in certain parts.
Experts have also warned of the harmful impact technology can have on our memory and attention span. The University of California team conducted a survey of more than 18,000 people aged between 18 and 99, and found 20% had problems with memory. Researchers were shocked greatly by the 14% of 18 to 39-year-old people who also worried about their memories.
Multi-tasking may shorten attention span, making it harder to focus and form memories, the researchers said, adding that youngsters may be particularly affected by stress.The underlined word "simultaneously" in Para.2 means _________.
A.on one’s own | B.at no time |
C.at the same time | D.by accident |
All of the following are possible effects of multi-tasking except _________.
A.saving time |

D.depression and anxiety |
What can increase grey-matter densities?
A.Sending a text message while listening to music . |
B.Students’ doing their homework. |
C.Taxi drivers’ learning the map of London. |
D.Speaking on the phone while watching TV. |
Which of the following can be the best title of this passage?
A.Media multi-tasking is becoming more popular. |
B.Multi-tasking shrinks the brain. |
C.Multi-tasking may shorten attention span. |

As we all know sewing-machine(缝纫机) repair is one of the fastest growing businesses in the world today. Newspapers, women’s magazines, high schools and colleges are all encouraging millions of American women to do their own sewing, not only to make their own shirts and sweaters, but also to make nice clothes for their husbands, sons, or boyfriends. The lattes figures(数字) show that over 89 million American women, because of the high costs of ready-to-wear clothing are now making almost all of their families’ clothes. Most of these women get great satisfaction from making the family clothes on their own sewing machines. So it is natural that the demand(要求) for excellent service of sewing machines is growing.
Think of it! 89 million or more sewing machines, not including another 10 million sewing machines in schools of all kinds, need service at least once a year, and quite possibly four or more times each year. I know some women who return their sewing machines to repairmen time after time to get them fixed properly. I’ve seen sewing machines come out of repair shops in worse condition than they were when they went in.
So I’ve decided to write an introduction book to sewing-machine repair and teach people how to repair their own sewing machines at home. It’s not that difficult. In the book, I will teach you everything you need to know about how to repair your sewing machine.The author wrote the passage to.
A.teach women to repair their sewing machines. |
B.explain his or her purpose in writing the book |
C.introduce the reasons for doing one’s own sewing |

We learn from the passage that sewing machines.
A.aren’t very difficult to be repaired |
B.cannot work well after one year |
C.don’t easily get broken |
D.need service 4 times a month |
It can be inferred from the passage that.
A.the book will also show you how to make nice clothes |
B.there are not enough sewing-machine-repair shops in America |
C.over 99 million sewing machines need service at least once a year |
D.the demand for excellent service of sewing machines grows the fastest in America |
Can you imagine exchanging the pleasure of city life for a quiet life in the countryside?
Many people want to move from the country to the city because they think that life in the city is more exciting and better than that in countryside, especially young people who like new, modern things. People like popular things and feel that they can only find the latest styles in the city.
However, it is possible to enjoy the higher quality of country life and still enjoy some of the advantages of living in the city.
Nowadays, traveling is fast and easy, and information can be found on the Internet, so many people are able to do their work in home offices. Because they have e-mail and personal computers, they don’t have to be in big cities to manage their businesses. It is not important where they actually work because the results of their work can be sent everywhere with e-mails. Therefore, there is no need to put up with all of the disadvantages of the city. Now they can escape busy city life to enjoy the quiet country life and still be able to have successful jobs.
Other people are interested in technological things and high-tech jobs and think they can only find them in big cities. If they want to find a job, especially a good position in a company, they think that they have to live in a city. For these jobs, they are willing to put up with many of the disadvantages of city life, such as crime, heavy traffic, and pollution.The main idea of this passage is that.

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 these questions is yes. To some extent our intelligence is given 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(随机地) from the population,it is likely that their degrees of intelligence will be completely different. If on the other hand we take two identical (完全相同的) 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 intelligence 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 that environment as well as birth playsa part. This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all, are likely to have similar degrees of intelligence.Which of these sentences best describes the writer’s point in Para. 1?
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. |

A.intelligence | B.life |
C.environments | D.housing |
The best title for this article would be_______.
A.On Intelligence |
B.What Intelligence Means |

Why doesn’t the unemployment rate ever reach zero? Economists, who generally believe that supply tends to meet demand, have long thought about this question. Even in good times, i.e. not now, there are people who can’t find work. And even in bad times, i.e. now, there are job openings. With over 14 million people out of work and looking for a job, you would think every available job would be filled. But that’s not the case. Not now and not ever.
On Monday, the Nobel Prize committee awarded the prize for economics to the three scholars who have done the most to explain this phenomenon. Two of the winners are Americans, Peter Diamond of MIT and Dale Mortensen of Northwestern. The third winner is Christopher Pissarides, who teaches at the London School of Economics and was born on Cyprus.
Like most of economics, what they have found about why the jobless and ready-employers don’t find each other seems obvious. You have to find out there is job opening you are interested in. Employers need to get resumes (简历). It takes a while for both employers and employees to make the decision that this is what they want. And these guys came up with a frame-work to study the problem of why people stay unemployed longer than they should and what can be done about it.
So what would today’s Nobel Prize winners do to solve the current problem of the unemployed? And does the awarding of the prize contribute to the politicians’ lowering joblessness?
Speaking from his north London home, Pissarides told The Associated Press the announcement came as “a complete surprise” though his work had already helped shape thinking on both sides of the Atlantic.
For example, the New Deal for Young People, a British government policy aimed at getting 18-24-year-olds back on the job market after long periods of unemployment, “is very much based on our work,” he said.
“One of the key things we found is that it is important to make sure that people do not stay unemployed too long so they don’t lose their feel for the labor force,” Pissarides told reporters in London. “The ways of dealing with this need not be expensive training – it could be as simple as providing work experience.”According to the writer, which is true about finding jobs?
A.It is always difficult to find a job. |
B.Everyone can find a job in good times. |
C.Contrary to popular belief, it is easier to find a job in bad times. |
D.It is possible to find a job even in times as bad as now. |
What is it that leads to their winning the prize?
A.They have found the reason for unemployment. |
B.They have put forward a set of ideas to deal with unemployment. |
C.They have found out why people don’t want to be employed. |
D.They have long studied the problem of unemployment. |
Which of the following statements is NOT true according to the passage?
A.Pissarides thinks his work surprising. |
B.The work of Pissarides has influenced many economists. |
C.Some of the winners’ ideas have been put into practice. |
D.It is probable that unemployed young people in Britain benefit from Pissarides’ work. |
According to Pissarides, _________ is effrctive in dealing with unemployment.
A.spending large sums of money on training |
B.teaching some knowledge of economics |
C.providing work experience |
D.keeping people unemployed for some time |
