How to learn English well?
It is well known that English is used most widely in the world. It is reported that many people use English as the first or second language. We should try our best to learn English well. But how can we learn English well? First, we shouldn’t give up. It’s true that English is sometimes really very difficult for us. But if we hold on, I think we will be good at it. Also, I think if we do a lot of practice, we will make progress, we should speak more and listen more often. That practice makes perfect is true. What is most important is that we must form a good habit of learning English. Such as, making good use of the dictionary and turning to the teachers when in trouble, I think If we do that, we’ll be able to learn English well easily.
