The Bilingual Brain
When Karl Kim immigrated to the United States from Korea as 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 don't use the same parts ofthe 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 lite.Peoplefrom both groups were placed inside the MRI scanner ,This allowed Kim and Hirsch to see which parts of thebrain were getting more blood and were more active.They asked people from both groups to think about whatthey had done the day before ,first in one language and then the other.They couldn't speak out loudbecause any movement would disrupt（干扰）the scanning.
Kim and Hirsch looked specifically at two language centers in the brain-Broca' s area, which isbelieved to control speech production,and Wernicke's area,which is thought to process meaning.Kim andHirsch found that both groups of people used the same part of Wernicke's area no matter what language theywere speaking.But their use of Broca's area was different.
People who learned a second language as children used the same region in Broca's area for both tneir first and second languages.People who learned a second language later in life used a different part of Broca's area for their second language.How does Hirsch explain this difference?Hirsch believes that when language is first being programmed in young children,their brains may mix the sounds and structures of all languages in the same area.Once that programming is complete,the processing of a new language must be taken over by adifferent part of the brain.
A second possibility is simply that we may acquire languages differently as children than we do asadults.Hirsch thinks that mothers teach a baby to speak by using different methods involving touch,sound and sight.And that is very different from learning a language in a high school or college class.

It can be inferred from the last paragraph that______.
A:students do better in high school than in college
B:bilingual children will learn better in college classes
C:mothers are good language teachers
D:it takes more time for adults to learn a second language

Successful Language Learners

1.Some people seem to have a knack for learning languages.They can pick up new vocabulary,master rules or grammar,and learn to write in the new language more quickly than others.They do not seem to be any more intelligent than others,so what makes language learning so much easier for them?Perhaps if we take a close look at these successful language learners,we may discover a few of the techniques which make language learning easier for them.
2.First of all,successful language learners are independent learners.They do not depend on the book or the teacher;they discover their own way to learn the language.Instead of waiting for the teacher to explain,they try to find the patterns and the rules for themselves.They are good guessers who look for clues and form their own conclusions.When they guess wrong,they guess again.They try to learn from mistakes.
3.Successful language learning is active learning. Therefore,successful learners do not wait for a chance to use the language;they look for such a chance.They find people who speak the language and they ask these people to correct them when they make a mistake.They will try anything to com-municate.They are not afraid to repeat what they hear or to say strange things;they are willing to make mistakes and try again.When communication is difficult,they can accept information that is inexact or incomplete.It is more important for them to learn to think in the language than to know the meaning of every word.
4.Finally,successful language learners are learners with a purpose.They want to learn the language because they are interested in the language and the people who speak it.It is necessary for them to learn the language in order to communicate with these people and to learn from them.They find it easy to practice using the language regularly because they want to learn with it.
5.What kind of language learner are you?If you are a successful language learner,you have probably been learning independently,actively,and purposefully.On the other hand,if your language learning has been less than successful,you might as well try some of the techniques outlined above.

Paragraph 3_________.
A:Ways to learn a language successfully.
B:Learning a language purposefully.
C:Learning a language actively.
D:Learning a language independently.
E:Learning from mistakes.
F:Learning to think in the target language.
