what shoud you do when in the college ,中英文都要

First, your question should be: How to speak good English?

But it doesn't matter if you make some mistakes when you speak English, as long as what you say can make sense to others.

Practice makes perfect. You should often use oral English. When you do not need to translate Chinese into English any more, you have reached a level of good communication. Then, only by then, you should pay attention to grammar and appropriate usage of words.

May you succeed!
