     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 when 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 is.

     "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 in 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 2 and 34. Reading, writing, and comprehension were all tested. The results

showed that the younger they started to learn, the better they will do it. "Studying a language means you

get an entrance to another world," explained the scientists.
