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?

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 (肌肉).

The study also found the younger people learn a second language, the greater the effect is. A team led by Dr. Andrea Mechelli, from University College London (UCL), 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 was. “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 learnt 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.

For the past few months, my three-year-old daughter has spent an hour every week learning a foreign language. She walks into a small room in a local school, where she and a handful of three and four-year-old spend the next hour dancing to ^“La Vaca Lola”, a song about a Spanish cow, creating finger puppets(木偶) to voice what they like and don’t like (me gusta, no me gusta) and shouting out which animals are big (grande) or small (pequeno).

She tells us little about the classes. In fact, for the first few weeks, nothing at all. I begin to wonder if it was a huge mistake (each lesson works out at about £9) but then I show her “La Vaca Lola” on YouTube. She shouts vaca with enthusiasm and with what I hope is a Spanish accent.

The wish to enroll(使……加入) her in language lessons came, like most things, gradually and then in a sudden rush. In my day job, I read and edit stories about the Chinese economy. For a long time, I felt that it would be good for her to learn another language but I had no great plan as to when.

Then I read Edward Luce’s The Retreat of Western Liberalism and all my thoughts and worry about the economy combined into a panic. Waking in a sweat, it seemed obvious that if my daughter was to have any kind of future, she would have to learn another language. Ideally (理想地) immediately.

I thought about Mandarin Chinese, one of the top 10 languages most important for our future, according to the British Council (others include Arabic, French, German, Portuguese, Italian, Russian, Dutch and Japanese). But there were no classes for young children nearby. There were, however, local Spanish classes—the number-one language on the list. When she started to sing “Incy Wincy Spider” in Spanish and English—helped by a Spanish nursery worker-our decision was made.
