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?

I fell in love with Yosemite National Park the first time I saw it, when I was 13. My parents took us there for camping.

About 15 years ago I started seeing a lot of 20 , like toilet paper, beer cans, and empty boxes, around the area. It’s 21 me why visitors started respecting the place 22 and treated such a beautiful home-like place this way.
I tried 23 trash(垃圾)myself, but the job was too big. I would 24 an hour or two on the job, only to find the area trashed all over again weeks later. Finally, I got so 25 it that I decided something had to change.
As a rock-climbing guide, I knew 26 about organizing any big event. But in 2004, together with some climbers, I set a date for a 27 . On that day, more than 300 people 28 . Over three days we collected about 6,000 pounds of trash. It was amazing how much we were able to 29 . I couldn’t believe the 30 we made—the park looked clean!
Each year volunteers come for the cleanup from everywhere. In 2007 alone, 2,945 people 31 42,330 pounds of trash.
I often hear people 32 about their surroundings. If you are one of them, I would say the only way to change things is by 33 rather than complaining. We need to teach by 34 . You can’t blame others 35 you start with yourself.
