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.

Kim and Hirsch find that children______.
A: use the same region in Broca's area to learn their first and second language
B:learn a second language slower than adults
C:are better at acquiring the sound system of a second language than adults
D:use special parts of the brain to program the structures of their first language

English and English Community

1There is no doubt that English is a useful language.The people who speak English
today make up the largest speech community in the world with the exception of speakers of
Chinese.
2 A speech community is similar to other kinds of communities.The people who make up
the community share a common language.Often they live side by side,as they do in a
neighborhood（街坊）,a village,or a city. More often they form a whole country. National
boundaries,however,are not always the same as the boundaries of a speech community.
A speech community is any group of people who speak the same language no matter where
they happen to live.
3 We may say that anyone who speaks English belongs to the English speech community.
For convenience（方便）,we may divide the speakers into two groups:one in which the
speakers use English as their native language,the other in which the speakers learn English
as a second language for the purpose of education,commerce,and so on.
4 Learning a second language extends one's vision and expands the mind.The history
and literature of a second language record the real and fictional（虚构的）lives of people
and their culture;a knowledge of them adds to our ability to understand and to feel as they
feel .Learning English as a second language provides another means of communication
through which the window of the entire English speech community becomes a part of our
heritage.

Paragraph 1________
A:Threat Posed by English
B:Definition of a Speech Community
C:Benefits of Learning a Second Language
D:Advantages of Learning Chinese
E:Two Groups of the English Speech Community
F:A Widely Used 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.

Why Don ' t Babies Talk Like Adults?

Over the past half-century,scientists have settled on two reasonable theories related to babytalk.One
states that a young child's brain needs time to master language,in the same way that it does to master other
abilities such as physical movement. The second theory states that a child's vocabulary level is the key fac-
tor. According to this theory,some key steps have to occur in a logical sequence before sentence formation
occurs.Children's mathematical knowledge develops in the same way.
In 2007,researchers at Harvard University,who were studying the two theories,found a clever way to
test them.More than 20,000 internationally adopted children enter the U.S.each year. Many of them no lon-
ger hear their birth language after they arrive,and they must learn English more or less the same way infants
do一that is,by listening and by trial and error. International adoptees don't take classes or use a dictionary
when they are learning their new tongue and most of them don't have a well-developed first language.All of
these factors make them an ideal population in which to test these competing hypotheses about how language
is learned.
Neuroscientists Jesse Snedeker,Joy Geren and Carissa Shafto studied the language development of 27
children adopted from China between the ages of two and five years.These children began learning English
at an older age than US natives and had more mature brains with which to tackle the task.Even so,just as
with American-born infants,their first English sentences consisted of single words and were largely bereft（缺
乏的）of function words , word endings and verbs. The adoptees then went through the same stages as typical
American-born children,though at a faster clip.The adoptees and native children started combining words in
sentences when their vocabulary reached the same sizes,further suggesting that what matters is not how old
you are or how mature your brain is,but the number of words you know.
This finding一that having more mature brains did not help the adoptees avoid the toddler-talk stage一
suggests that babies speak in babytalk not because they have baby brains,but because they have only just
started learning and need time to gain enough vocabulary to be able to expand their conversations.Before
long,the one-word stage will give way to the two-word stage and so on. Learning how to chat like an adult is
a gradual process.
But this potential answer also raises an even older and more difficult question.Adult immigrants who
learn a second language rarely achieve the same proficiency in a foreign language as the average child raised
as a native speaker. Researchers have long suspected there is a"critical period"for language development,
after which it cannot proceed with full success to fluency.Yet we still do not understand this critical period or
know why it ends.

What is the writer's main purpose in Paragraph 2?
A:To reject the view that adopted children need two languages.
B:To argue that culture affects the way children learn a language.
C:To give reasons why adopted children were used in the study.
D:To justify a particular approach to language learning.
