Stick to speaking, listening, reading and writing, and your English will be great.

First of all, you should have a certain vocabulary, then read more articles, and it is best to recite more good articles, paragraphs and sentences. Only in this way can we improve our sense of language and avoid hesitating when speaking English.

The less you talk, the more nervous you get. It's okay. Tell yourself in the mirror. Read more books and watch more American dramas.
