Hi Li Ming,

There are many way you can improve your spoken English. First, read out loud the reading from your textbook and pay attention to pronunciation. Second, you mentioned you were afraid of answering questions in class. You can go to your English teacher after class to practice. Another good way to practice is to listen to English radios. You can follow what they say in the radio to practice.

When you are good at pronunciation, I think you will not be afraid of answering questions in class. At that time, you can participate in class more and that will help a lot.
