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 .

   Britain is a very worldwide country. Women in Britain are usually independent and used to entering public places by themselves. The British are generally quite tolerant - they like to help if they can so don't be afraid to ask for help. The British people sometimes seem a little cool and it needs to take time to build close friendships. However,most people respond politely and positively to offers of friendship. Don't forget that if they are not familiar with your culture,they won't understand your needs and concerns unless you explain them.

But on campus you might be surprised by the lack of formality(遵守礼节). In this relaxed attitude ,most members of faculty (全体教师)enjoy being with students and joining in conversation whether or not it is directly related to studying work. Social spaces and common rooms on campus will usually  contain a mixture of staff and students informally chatting over tea or coffee.

For drinking, alcohol is offered to anyone aged over 18. It's perfectly acceptable for adults to drink alcohol in proper amounts. For many British people ,drinking is a common part of social life -“ going out for a drink” is how they relax or spend time with friends. This doesn't mean that you have to drink alcohol. If you don't want to,you can always ask for a non-alcoholic drink instead.

You know,many people in Britain smoke. However, in some ways smoking is less acceptable than drinking, and from summer 2010 smoking was not allowed in all pubs,clubs and restaurants in England. Most restaurants provide separate smoking and non-smoking areas, and smoking is not allowed in many public places including  buses and the London Underground. If you smoke in these places,you have to pay a fine. If you are eating or drinking with friends - especially at someone else's house - it is polite to ask before you light your cigarette.

【小题1】If you want to make your British friends understand you,you’d better _____________ .
A.tell them your own country's culture

D.learn the British way to express your needs
【小题2】What can we infer from the second paragraph?
A.Students there usually don't respect their teachers.

【小题3】Why is drinking an important part of people's social life in Britain?

   Pablo Picasso was born in Malaga,Spain in 1881.When he died in 1973,he was ninety-one years old. But he still took up his paints and brushes to start a new picture as if he were seeing things for the first time,which is why we have called him the youngest painter. Young people are always trying new things and new ways of doing things. They don't hesitate to attempt one thing after another. Eager to experiment, they welcome new ideas.

When he was over ninety this great painter still lived his life like a young man. He was still restlessly looking new ideas and new ways to use his artistic materials. No one knew what to expect from him next. No one could be sure what kind of picture he would produce. If he had painted a picture of you, it might have looked exactly like you. Or it might have been all lines, squares, circles and strange-colored shapes. It might not have looked like human at all.

At such times Picasso was trying to paint what he saw with his mind as well as with his eyes. He put in the side of the face as well as the front. He may have painted it flat, as though it had no depth. Sometimes he seemed to paint just as a child painted, simply for his own pleasure. He didn't imitate others.

Most painters discover a style of painting that suits themselves and stick to that, especially if people admire their pictures. But Picasso was like a man who had not yet found his own particular style of painting. He was still struggling to find perfect expression for his own uneasy spirit.

The first thing one noticed about him was the look of his large, wide-open eyes. Gertrude Stein, a famous American writer who knew him in his youth, mentioned this hungry look, and one can still see it in pictures of him today.

Picasso painted a picture of Gertrude Stein in 1906. She visited the painter's studio eighty or ninety times while he painted her picture. While Picasso painted they talked about everything in the world that interested them. Then one day Picasso wiped out the painted head on which he had worked for so long. "When I look at you I can't see you any more!" he said.

Picasso went away for the summer. When he returned he went at once to the unfinished picture in the corner of his studio. Quickly he finished the face from memory. He could see the woman's face more clearly in his mind than he could see it when she sat in the studio in front of him.

Picasso was often attacked for this new, sometimes frightening style. It produced pictures like some of our worst dreams. The camera has made it unnecessary for painters to make exact representations of what they see. A camera can reflect real life more exactly. What great paintings give us is a view of life through one man's eyes, and every man's view is different.

【小题1】The example of the picture of Gertrude Stein is raised mainly to indicate Picasso ________.
A.was particular about his works
B.used more of his mind to paint
C.was a man of responsibility
D.was not appreciated at his time
【小题2】The last paragraph mainly illustrates that ________.
A.Picasso's paintings are beyond some people's comprehension
B.Picasso's paintings are too frightening
C.Picasso paints from his unique perspective
D.cameras are better at presenting real life
【小题3】Which of the following can best summarize Picasso's paintings?
A.Frightening and unpredictable.
B.Concrete and straightforward.
C.Abstract and unconventional.
D.Rigid and unusual.
【小题4】The best title for the passage might be "________".
A.The youngest painter in the world
B.What to expect from Picasso
C.How Picasso developed his way of painting
D.The greatest painter the world has ever seen
