In order to acquire a second language， learners will subconsciously use their first language knowledge in learning a second language. This is know as language t（）.

It’s an activity when the target language is used by the learner for communication purpose（goal）in order to achieve an outcome that can be shared with others.Learners are meaning what they are saying and making free use of language to express what they want to.Specific language forms are not prescribed.This is the definition of________.

A.Grammar Translation MethoD
B.Task-based Learning Approach
C.Audio-lingual MethoD
D.Total Response MethoD.

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

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 eas- ier for them?Perhaps if we take a close look at these successful language learners,we may dis- cover 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 guess-ers 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 lan-guage and they ask these people to correct them when they make a mistake.They will try anything to communicate .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.

Some Things We Know About Language
Many things about language are a mystery,and many will always remain so.But some things we do know.
First,we know that all human beings have a language of some sort. There is no race of men anywhere on earth so backward that it has no language,no set of speech sounds by which the people communicate with one another. Furthermore,in historical times,there has never been a race of men without a language.
Second,there is no such thing as a primitive language.There are many people whose cultures are undeveloped,who are,as we say,uncivilized,but the languages they speak are not primitive .In all known languages we can see complexities that must have been tens of thousands of years in developing.
This has not always been well understood;indeed,the direct contrary has often been stated.
Popular ideas of the language of the American Indians will illustrate.Many people have supposed that the Indians communicated in a very primitive system of noises.Study has proved this to be nonsense .There are,or were,hundreds of American Indian languages,and all of them turn out to be very complicated and very old.They are certainly different from the languages that most of us are familiar with,but they are no more primitive than English and Greek.
A third thing we know about language is that all languages are perfectly adequate. That is, each one is a perfect means of expressing the culture of the people who speak the language.
Finally,we know that language changes.It is natural and normal for language to change;the only languages which do not change are the dead ones.This is easy to understand if we look backward in time.Change goes on in all aspects of language.Grammatical teatures change as do speech sounds,and changes in vocabulary are sometimes very extensive and may occur very rap-idly. Vocabulary is the least stable part of any language.

In the second paragraph the passage tells us that______.
A: some backward race doesn't have a language of its own
B: some race in history didn't possess a language of its own
C: any human race,whether backward or not,has a language
D: some races on earth can communicate without 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.

Kim and Hirsch looked specifically at two language centers in the brain-Broca's area,which is believed to control speech production,and Wernicke's area,which is thought to process meaning.Kim and Hirsch found that both groups of people used the same part of Wernicke's area no matter what language they were speaking. ______(48) People who learned a second language as children used the same region in Broca's area for both their 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.______(49)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 a different part of the brain. A second possibility is simply that we may acquire languages differently as children than we do as adults.Hirsch thinks that mothers teach a baby to speak by using different methods involving touch'sound, and sight.______(50)

______(46)
