     One is not born able to speak a language. One is born able to make a noise. I have heard babies cry in

America and in China. I can't tell any difference. But when I hear someone from America speak English

and hear someone speak Chinese, I can tell you there are a lot of differences.

     I believe a common problem with Chinese students' learning English is that they were not taught to think

in English. They have an idea spoken in English and want to translate the idea into Chinese, Then they think

in Chinese of the proper reply and translate it into English. After a long period of speaking the language, one

begins to think in the foreign language naturally. You will learn faster if you begin to think in English at the

very beginning of your study. Many students ask me: What can I do to improve my spoken English?

      My reply is: The more English you speak, the better English you will speak. There are many things you

can do to improve your spoken English. Of course, the best way is to live where English is spoken as a

language of the country.
