Dear Lin Dan:
I am glad to receive your letter . From your letter, I know you are facing the problem on how to communicate with other people. However , it is easy to change the situation . Here are some tips for you.
In the first place, you should be brave and talk to other students actively. When you are familiar with each other, you can communicate with them well. Secondly, you can join in some discussions and show interest in other students ideas. Because you can get to know different people and let them see you are friendly. I think it is a good way to find new friends. In addition, you can begin the conversation by asking about their likes and dislikes . You will soon find people with the same interests in this way. When you have difficulty with study and life, you can turn to teachers or your classmates for help. It is also a good way to exchange your ideas. Last but not least, in your daily life, you can arrange your time regularly. You can do some sports with your classmates, such as playing basketball, playing football and so on. For one thing ,it can keep healthy. For another , it can help you make more good friends.
I hope you will find these suggestions helpful.
