On Language Environment and Language Learning

In my thesis,at first,I expound the distinction between native language and foreign language,that is what is native language and what is foreign language. I make it clear that the same language is separately called the native language or foreign language just because of the different language environment. And then,the body which expound that the different environment causes the three differences: A.The different purpose of acquiring and learning language. B.The different psychological activities in the process of learning language. C.The different process or strategy of learning language. The above mentioned proves that it is very important for teachers to try their best to create much more language circumstances. So in the conclusion,I propose six constructive effective measures which can help teacher to create much more foreign language environment as many as possible so as to do well in teaching.
