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.

“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 thirty-four. 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. that language can help brain power        D. language learning and maths study

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

In the last two paragraphs, the author wants to tell us that _________.

A. learning a second language is the same as studying maths

B. early learning of a second language helps you a great deal in studying other subjects

CItalian is the best choice for you as a second language

D. you’d better choose the ages between 2 and 34 to learn a second language

“Birds are not as loyal to their partners as you might think, with divorce, child abandonment and remarriage a common part of birds’ life,” a new book has shown. Author and biology professor Bridge Stutchbury, dispels the love-bird belief that birds pair up for life. “In terms of the top 10 beliefs about birds, the lasting pair bonds that we think about, do occur in some birds, but in most of the little songbirds that we studied, no,” the professor from York University in Toronto said. The divorce rate among greater flamingos is 99 percent.

Stutchbury’s book, The Private Lives of Birds, based on 20 years of research from radio filming and DNA testing shows male Acadian flycatchers fertilize(使受孕) females far away from their home nests, “ The main discovery is that so many birds do divorce for what humans would describe as selfish reasons,” Professor Stutchbury said. She noted that females may seek out males that are more colorful and better singers, or look to “step up in the world” and move to areas that are safer and have more food. “Females are looking for the highest quality male so that their children will be of high quality,” she added.

Professor Stutchbury said shorter summers may drive females to leave their nests before their young are fully grown up so they can quickly find new mates（配偶） and lay more eggs, leaving the males to feed the hungry chicks on their own.

Males can double their success in producing children by fertilizing neighboring females, but only “mates” care for the young, and some are none the wiser. “  They can’t tell when the egg comes out and whether it’s theirs or not,” She said. “They have no way to know.”

Divorce is surprisingly common among birds, and most live with one partner for only a few months or years. Divorce rates range from 99 percent in the greater flamingo to zero in the wandering albatross(信天翁).
