第一篇:The Bilingual Brain
When Karl Kim immigrated to the United States from Korea s a teenager, he had a hard time learning English. Now he speaks it fluently, and he had a unique opportunity to see how our brains adapt to a second language. As a graduate student, Kim worked in the lab of Joy Hirsch, a neuroscientist in New York. Their work led to an important discovery. They found evidence that children and adults dont use the same parts of the brain when they learn a second language.
The researchers used an instrument called an MRI( magnetic resonance imaging) scanner to study the brains of two groups of bilingual people. One group consisted of those who had learned a second language as children.. The other consisted of people who, like Kim, learned their second language later in life. People from both groups were placed inside the MRI scanner. This allowed Kim and Hirsch to see which parts of the brain were getting more blood and were more active. They asked people from both groups to think about what they had done the day before, first in one language and then the other. They couldnt speak out loud because any movement would disrupt the scanning.
