    First, you should build up confidence（建立自信）. If you believe that you can, then you will learn. When you read or listen to something , you may not be able to understand it all. Don't worry. You can use a dictionary to help you. You can ask your teacher or friends to help you. Do not be afraid of making mistakes. You can learn from mistakes.

    Second, practice using English. For example, write a diary in English every day, and you will be able to write better. Speak English whenever you can. You may practice with your friends after class. Then you will be able to speak better.

    Remember the famous saying, “Practice makes perfect.” The more you practice using English, the better you will learn it.
