A study made by University of Sussex 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 . The researchers said : “ Simultaneously(同时), using mobile phones , laptops and other media devices could change the structure of our brains . ” Worryingly , the part of the brain that shrinks is involved in processing emotion . The finding 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 web . The volunteers were then given brain scans which showed they had less grey matter in a region called the anterior cingulated cortex ( ACC ) . The findings held even when differences in personality were taken into account . The study , published in the journal PLOS ONE , is the first to make a link between multi-tasking and the structure of the brain .
Researcher KepKeeLoh said : “ Media multi-tasking is become more popular in our lives today and there is growing concern about its impacts on our cognition and social-emotional well-being . ” He added that more researches are needed to prove that multi-tasking shrinks the brain . This is because it is also possible that people with less grey matter in the ACC are more likely to use lots of devices simultaneously .
Scientists have previously described brain structure can be altered on prolonged exposure to new environments and experience . Other studies have shown that training – such as learning magic or taxi drivers learning the map of London – can increase grey matter densities(密度)in certain parts .
【小题1】What can we learn about grey matter from the passage ?
A.Watching the TV for a long time can reduce grey matter .
B.The decrease of grey matter in the ACC affects emotion .
C.People with less grey matter prefer to use media devices .
D.Taxi drivers in London have more grey matter than others .
【小题2】We can know about the study by University of Sussex that __________ .
A.the volunteers in it have lower grades at school
B.it can change the structure of grey matter in our brain
C.it is the first to link multi-tasking with the structure of the brain
D.the findings of it have been supported by some other researches
【小题3】 How does the researcher , KepKeeLoh , feel about the study ?
A.Surprised .B.Cautious .
C.Disappointed .D.Confused .
【小题4】What’s the purpose of the passage ?
A.To inform people of the findings of a research .
B.To stress the importance of grey matter in our brain .
C.To advise people to do more training about our brain .
D.To warn people of the possible danger of media devices .

All over the world mothers and fathers teach their children manners. Other children may have manners that are not like yours. There are all kinds of manners.
Many years ago, children who had good manners were seen and not heard. They kept quite quiet if grown-ups were talking. Today, well-mannered children have more freedom.
Sometimes good manners in one place are bad manners in other places.
Suppose you are a visitor in the land of Mongolia. Some friends ask you to eat with them. What kind of manners do they want you to have? They want you to give a loud “burp” after you finish eating. Burping would show that you liked your food.
In some countries, if you give a loud burp, you are told to say “excuse me, please.”
In many places people like to eat together. But in some parts of  Polynesia it is bad manners to be seen eating at all. People show good manners by turning their backs on others while they eat.
What are manners like in an East African town? The people try not to see you. They are being polite. You may see a friend. He may not see you at all. If you are polite, you will sit down beside him. You will wait until he finishes what he is doing. Then he will talk to you.
Suppose you visit a friend in Arabia. You should walk behind the other tents until you come to his tent. If you pass in front of the other tents, you will be asked into each one. The people will ask you to eat with them. And it is bad manners if you say no.
Manners are different all over the world. But it is good to know that all manners begin in the same way. People needed ways to show that they wanted to be friends.
【小题1】In an East African town, the people try not to see you. This is because_________.

Steve Jobs knew from an early age that he was adopted (收养). “My parents were very open with me about that,” he recalled. He had a clear memory of sitting in the yard of his house, when he was six or seven years old, telling the girl who lived across the street. “Does that mean your real parents didn’t want you?” the girl asked. “My whole world was falling apart,” according to Jobs. “I remember running into the house, crying. And my parents said, ‘No, you have to understand.’ They were very serious and looked me straight in the eyes. They said, ‘We specially picked you out.’ Both of my parents said that and repeated it slowly for me. And they stressed every word in that sentence.”
Abandoned (被抛弃). Chosen. Special. These words became part of who Jobs was and how he thought of himself. His closest friends think that the knowledge that he was given up at birth left some scars (伤疤). “He wants to control everything because of his personality and the fact that he was abandoned at birth,” said one longtime colleague (同事), Del Yocam.“He wants to control his environment, and he sees his product as a part of himself.” Greg Calhoun, who became close to Jobs right after college, saw another effect. “Steve talked to me a lot about being abandoned,” he said. “It caused great pains and made him independent. He was different from others because he was born into a different world.”
Later in life, Jobs became a father and abandoned one of his children. Andy Hertzfeld, who worked with Jobs at Apple in the early 1980s, is among the few who remained close to Jobs. “To understand Jobs, you have to know the reason why he can’t control himself and is sometimes cruel and harmful to others,” he said. “That goes back to being abandoned at birth. The real problem was the theme of abandonment in Steve’s life.”
【小题1】Which of the following is true about Jobs’ childhood?
A.He left his parents at the age of six or seven.
B.He was shocked knowing he was abandoned.
C.He couldn’t remember how he was abandoned.
D.His parents chose him because his family was poor.
【小题2】What did Del Yocam think of Jobs?
A.He hated to be born with scars.
B.He liked to get things under control.
C.He enjoyed good working environment.
D.He wanted to influence everyone.
【小题3】What does the underlined word “it” in the second paragraph refer to?
A.The fact that Jobs was abandoned.
B.Jobs’ pain from the abandonment.
C.Jobs’ talk with Greg Calhoun.
D.The world where Jobs lived.
【小题4】What can be inferred from the last paragraph?
A.Jobs didn’t bring up any children.
B.Jobs had a lot of close friends.
C.Abandonment influenced Jobs.
D.Nobody likes Jobs’ character.
【小题5】What is the best title for this text?
A.Steve JobsB.Jobs’ Childhood

   If you have a chance to go to Finland, you will probably be surprised to find how “foolish” the Finnish people are.

Take the taxi drivers for example. Taxis in Finland are mostly high-class Mercedes-Benz with a fare of two US dollars a kilometer. You can go anywhere in one, tell the driver to drop you at any place, say that you have some business to attend to, and then walk off without paying your fare. The driver would not show the least sign of anxiety.

The dining rooms in all big hotels not only serve their guests, but also serve outside diners. Hotel guests have their meals free, so they naturally go to the free dining rooms to have their meals. The most they would do to show their good faith is to wave their registration card (登记卡) to the waiter. With such a loose check, you can easily use any old registration card to take a couple of friends to dine free of charge.

The Finnish workers are paid by the hour. They are very much on their own as soon as they have agreed with the boss on the rate. From then on, they just say how many hours they have worked and they will be paid accordingly (相应地).

With so many loopholes (漏洞) in everyday life, surely Finland must be a heaven to those who love to take “petty advantages”. But the strange thing is, all the taxi passengers would always come back to pay their fare after they have attended to their business; not a single outsider has ever been found in the free hotel dining rooms. And workers always give an honest description of the exact hours they put in. As the Finns always act on good faith in everything they do, living in such a society has turned everyone into a real “gentleman”.

In a society of such high moral practice, what need is there for people to be on guard against others?

【小题1】What can a passenger do while taking a taxi in Finland?
A.Go anywhere without having to pay the driver.
B.Pay two US dollars for a taxi ride without any hesitation.
C.Be accepted by the taxi driver wherever he wants to go.
D.Get good faith evidence before leaving without paying.【小题2】What can we learn from Paragraph 3 about big hotels in Finland?
A.Their dining rooms are mostly poorly decorated.
B.They provide meals for any diners.
C.Their waiters provide free wine and charge for food.
D.Their registration rule is quite strict.【小题3】What can we infer from Paragraph 4?
A.The workers in Finland are paid unfairly.
B.The workers are always honest with their working hours.
C.The workers and their bosses will have an argument over the pay.
D.The bosses in Finland are too busy to check the working hours of their employees.【小题4】The word “those” in the last but one paragraph probably refers to __________.
A.people who are dishonest   B. people who often have meals in big hotels
B.people who often take taxis D. people who are worthy of trust

   A generation of parents raised according to the permissive principles of postwar childcare experts is rediscovering the importance of saying "No" to their children. They are beginning to reclaim the house as their own. Even spanking (打屁股) is back.

While today's parents do not want to return to the Victorian era (时代) — when children were seen, spanked, but not heard — there is a growing acknowledgement that the laissez-faire approach produced a generation of children running rings around puzzled parents struggling to restore order.

Janthea Brigden, a trainer with Parent Network, says: “The problem is that parents don't want all that controlling things. What they want is to be able to discipline (管教) their children through teaching and encouraging."

According to Steve Biddulph, the author of More Secrets of Happy Children, the permissive era was often just an excuse to ignore children. He believes discipline involves firm but friendly teaching and does not need to involve punishment. He teaches a method called "stand and think”, where a child is helped to figure out what is wrong and how to get it right. Mr. Biddulph understands parents using spanking, but lie is against it. "The happiest children are those who know Mum and Dad are in charge. As children grow into their teens, more negotiation can take place, such as: Prove you can be home safely by 1l pm, and we might let you stay out till midnight."

“There is no good evidence that an occasional, properly administered spanking is harmful in any way.”says John Rosemond, an American who has won a huge following by calling for "parent power". It is pure nonsense to believe that restricting children to their room as a punishment could make them have negative feelings about the room and cause sleep problems.

Mr. Rosemond tracks the overturning of traditional family values to the end of the Second World War. He blames the change of the American family into a child-centered, self-respect-oriented (以……为导向) unit on psychologists and social workers, who for 30 years have weakened traditional approaches. Previous generations of American parents raised children not by the book, but by self-evident truth, he says. Children should be seen and not heard. If you make your bed, you'll have to lie in it. He says that those phrases contain time-honored understanding and principles that helped children to develop what we refer to as the "three Rs" of parenting: respect, responsibility and resourcefulness.

【小题1】Which is closest to the meaning of the underlined word "laissez-faire" in the second paragraph?
A.Let it be. B.Go for it.
C.Get it right. D.Take it easy.
【小题2】If his child did something wrong, Steve Biddulph would ______.
A.give him a good beating
B.lock him up in a dark room
C.ask him to stand in a corner for hours
D.help him find out the problem and solution
【小题3】By mentioning the underlined part in the last paragraph, Mr. Rosemond .
A.blames parents for ignoring children's rights
B.reminds parents to communicate more with children
C.encourages parents to involve children more in family affairs
D.explains how previous generations of parents raised children
【小题4】What does the passage mainly talk about?
A.The causes of discipline problems.
B.The best way to discipline children.
C.Different opinions on ways of parenting.
D.Differences between parents of different times
