Knowing how to read, write and talk in one language is enough for many people. They prefer to focus their energy on other things that improve their lives. Scientists, however, continue to confirm that bilingualism, the ability to speak two languages fluently, has more benefits than many realize.
First, it's good for a child's brain. Learning a second language improves their academic achievements. Many studies have shown that children who learn a foreign language get better grades at school. Bilingual children also display a better facility in their native language. Their grammar, vocabulary and spelling skills are stronger than those of single-language speakers. Children who learn a second language become expert problem-solvers and creative thinkers. That's because their brains are constantly working to sort out which language to speak and when. Studies further show that bilingual teens are better at multitasking.
Multilingual parents understand the benefits of learning more than one language. Ben Mazor of Montreal speaks English, French and Hebrew. He says, "Kids' brains are like a sponge (海绵). They absorb everything. It comes to them so easily while they're young. So why not give them the chance to learn another language？"
A number of studies show that bilingualism is valuable to the brain later in life. Scottish researchers did a study using data from 835 native English speakers, who took an 1Q test at the age of 11. They were tested again in their 70s. Researchers then compared the tests. Those who spoke two or more languages had obviously better cognitive (认知的) abilities. Dr. Thomas Baka, co-author of the study, concluded, "Our results suggest a protective effect of bilingualism against age-related cognitive decline."
So, who would refuse the benefits of learning a second language？
