[1]If you think 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?

[2]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.

[3]The researchers also found the effect is greater on the younger people who learn a second

language.

[4]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(通两种

语言的人)", who had learnt a second language before the age of five, as well as a number of

later learners.

[5]Scans showed that grey matter density(密度)in the brain was greater in bilinguals than in people

without_________. But the longer a person waited before mastering a new language, the smaller

the difference was.

[6] "Our findings suggest that the structure of the brain is changed by the experience of learning

a second language," said the scientists.

[7]It means that the change itself increases the ability to learn.

[8]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," he said, "You are actually going beyond language and have a

better understanding of different ideas."
