If English means endless new words, difficult grammar and sometimes strange pronunciation, you are wrong. Haven't you noticed that you have become smarter since you started to learn a language?

According to a new study by a British university, learning a second language can lead to an increase in your brain power. Researchers found that learning other languages changes grey matter. This is the area of the brain which processes information. It is similar to the way that exercise builds muscles.?

The study also found the effect is greater, the younger people learn a second language.?

A team led by Dr Andrea Mechelli, from University College London, took a group of Britons who only spoke English. They were compared with a group of “early bilinguals” who had learnt a second language before the age of five, as well as a number of later learners.

Scans showed that grey matter density(密度)in the brain was greater in bilinguals than in people without a second language. But the longer a person waited before mastering a new language, the smaller the difference.?

“Our findings suggest that the structure of the brain is changed by the experience of learning a second language,” said the scientists.?

It means that the change itself increases the ability to learn.?

Professor Dylan Vaughan Jones of the University of Wales, has researched the link between bilingualism and maths skills. “Having two languages gives you two windows on the world and makes the brain more flexible(灵活的),”he said. “You are actually going beyond language and have a better understanding of different ideas.”

The findings were matched in a study of native Italian speakers who had learned English as a second language between the ages of two and 34.Reading, writing, and comprehension were all tested. The results showed that the younger they started to learn, the better. “Studying a language means you get an entrance to another world,”explained the scientists.?

The main subject talked about in this passage is_______.?

A. science on learning a second language?

B. man's ability of learning a second language?

C. language can help brain power?

D. language learning and maths study?

In the second paragraph, the writer mentions “exercise” in order to_______.

A. say language is also a kind of physical labor?

B. prove that one needs more practice when he(she)is learning a language?

C. to show the importance of using the language when you learn the language?

D. make people believe language learning helps grey matter work well?

The underlined word “bilingual” probably means_______.?

A. a researcher on language learning

B. a second language learner?

C. a person who can speak two languages

D. an active language learner ?

We may know from the scientific findings that_______.?

A. the earlier you start to learn a second language the higher the grey matter density is

B. there is no difference between a later second language learner and one who doesn't know a second language?

C. the experience of learning a second language has bad effect on people's brain

D. the ability of learning a second language is changing all the time?

Early one morning,more than a hundred years ago,an American inventor called Elias Howe finally fell asleep.He had been working all night on the design of a sewing machine but he had run into a very difficult problem: It seemed impossible to get the thread to run smoothly around the needle.

Though he was tired,Howe slept badly.He turned and turned.Then he had a dream.He dreamt that he had been caught by terrible savages whose king wanted to kill him and eat him unless he could build a perfect sewing machine.When he tried to do so,Howe ran into the same problem as before.The thread kept getting caught around the needle.The king flew into the cage and ordered his soldiers to kill Howe.They came up towards him with their spears raised.But suddenly the inventor noticed something.There was a hole in the tip of each spear.The inventor awoke from the dream,realizing that he had just found the answer to the problem.Instead of trying to get the thread to run around the needle,he should make it run through a small hole in the center of the needle.This was the simple idea that finally made Howe design and build the first really practical sewing machine.

Elias Howe was not the only one in finding the answer to his problem in this way.Thomas Edison,the inventor of the electric light,said his best ideas came into him in dreams.So did the great physicist Albert Einstein.Charlotte Bronte also drew in her dreams in writing ?Jane Eyre.?

To know the value of dreams,you have to understand what happens when you are asleep.Even then,a part of your mind is still working.This unconscious(无意识的),but still active part understands your experiences and goes to work on the problems you have had during the day.It stores all sorts of information that you may have forgotten or never have really noticed.It is only when you fall asleep that this part of the brain can send messages to the part you use when you are awake.However,the unconscious part acts in a special way.It uses strange images which the conscious part may not understand at first.This is why dreams are sometimes called “secret messages to ourselves ”.

According to the passage,Elias Howe was_________.

A.the first person we know of who solved problems in his sleep

B.much more hard-working than other inventors

C.the first person to design a sewing machine that really worked

D.the only person at the time who knew the value of dreams

The problem Howe was trying to solve was_________.

A.what kind of thread to use

B.how to design a needle which would not break

C.where to put the needle

D.how to prevent the thread from getting caught around the needle

Thomas Edison is spoken of because_________.

A.he also tried to invent a sewing machine

B.he got some of his ideas from dreams

C.he was one of Howe's best friends

D.he also had difficulty in falling asleep

Dreams are sometimes called “secret messages to ourselves” because _________.

A.strange images are used to communicate ideas

B.images which have no meaning are used

C.we can never understand the real meaning

D.only specially trained people can understand them

　A few days ago I asked my sons’ governess（女家庭教师）Julia to come into my study. “Be seated, Julia, ”I said, “Let’s settle our accounts. I guess you most likely need some money, but maybe you’re too polite to mention it. Now then, we agreed on thirty dollars a month...”

　　“Forty.”

　　“No, thirty. I made a note of it. I always pay our governess thirty. Well, um, you’ve been here two months, so...”

　　“Two months and five days.”

　　“Exactly two months. I made a special note of it. That means you have sixty dollars coming to you. Take off nine Sundays... you know you didn’t work with Tom on Sundays, you only took walks. And three holidays... ”Julia was biting her finger nail nervously, her face red, but - not a word.

　　“Three holidays, therefore take off twelve dollars. Four days Tom was sick and there were no lessons, as you were occupied only with Dick. Three days you had a toothache and my wife gave you permission not to work after lunch. Twelve and seven - nineteen. Take nineteen off ... that leaves. hmm.... forty one dollars. Correct？”

　　Julia’s left eye reddened with tears welling up. Her chin trembled; she coughed nervously and blew her nose, but - still not a word.

　　“Around New Year’s Day you broke a teacup and a saucer; take off two dollars. The cup cost more, it was a treasure of the family, but- forget it. When didn’t I take a loss! Then, due to your neglect （疏忽）, Tom climbed a tree and tore his jacket; take away ten. Also due to your carelessness the maid stole Dick’s shoes. You ought to watch everything! You get paid for it. So, that means five more dollars off. The tenth of January I gave ten dollars.”

　　“You didn’t. ”sobbed Julia.

　　“But I made a note of it.”

　　“Well... if you say so.”

　　“Take twenty seven from forty one -that leaves fourteen.”

　　Both her eyes were filled with tears. Beads of sweat stood on the thin pretty little nose. Poor girl!

　　“Only once was I given any money,” she whispered, her voice trembling, “and that was by your wife. Three dollars, nothing more.”

　　“Really? You see now, and I didn’t know that! Take three from fourteen.. leaves eleven. Here’s your money, my dear. Three, three, three, one and one. Here it is !”

　　I handed her eleven dollars. She took them and pocketed them.

　　“Merci （法语: 谢谢）,”she whispered.

　　I jumped to my feet and started pacing the room. I was overcome with anger. “For what, this - ‘merci’?” I asked.

　　“For the money. ”

　　“But you know I’ve cheated you - robbed you ! I have actually stolen from you ! Why this‘merci’？”

　　“In my other places they didn’t give me anything at all.”

　　“They didn’t give you anything? No wonder! I played a little joke on you, a cruel lesson, just to teach you... I m going to give you all the eighty dollars! Here they are in the envelope all ready for you... Is it really possible to be so spineless （懦弱）?Why didn’t you protest? Why were you silent? Is it possible in this world to be without teeth and claws（爪）—to be such a fool?”

　　Embarrassed, she smiled. And I could read her expression,“It is possible.”

　　I asked her pardon for the cruel lesson and, to her great surprise, gave her the eighty dollars. She murmured her little“merci”several times and went out. I looked after her and thought,“How easy it is to crush the weak in this world !”

This was no ordinary class. The students who came together were all science or engineering professors at Cornell University. They had interrupted their research to accept an invitation to take part in an unusual experiment: “an interesting week of poetry.” This class was part of a study to answer the questions: Why is science difficult for many nonscience students? What can teachers learn about teaching if they take a class that is not in their field?

The students in the poetry class listened to lectures and took notes. They had reading tasks and had to write three short papers. All students noticed one thing – the importance of spoken words. In science and engineering classes, the instructors put tables and drawings on the blackboard. But in this poetry class, the instructors just talked. They didn’t write anything on the board.

The scientists and engineers noticed one similarity between science and poetry. In both subjects, students need to find layers (层次)　of meaning . Some layers are simple, clean, and on the surface; other layers are deeper and more difficult. This search for different levels of meaning doesn’t happen much in undergraduate(本科)　science classes, but it is important later, in graduate school. And it is always important in humanities(人文科学).

Both the poetry instructors and their students learned something about teaching from this experience. One poetry instructor, for example, now sees the importance of using informative as he teaches. Most of the scientists agreed on several points. First, humanities classes might help science students to see patterns and decide which information is important. Second, the poetry class was fun. One engineer decided, “We need to change the way we teach engineering to make to make it an enjoyable experience for students.”

But perhaps the most important result of the experience was this; All of the professors began to think about how they teach and how they cam teach better.
