Dear Li Ming,
Thank you for your letter.
From your letter, I know that it is overwhelmingly difficult for you to get accustomed(fit in) to your new class and you’re profoundly worried.
There are chiefly three reasons for it. To begin with, maybe it’s typical of you to be too shy to get along with your classmates. Furthermore, the time you spend with your classmates is too short. Apart from the above reasons, your classmates are not familiar with you.
On a personal note, I hold the point of view that you should first firmly believe that smile is integral to communication. In addition, it is vital to help classmates when necessary and I believe that they are the ones with whom you can settle into easy communication.Last but not least, I will send a letter to your classmates to help them relate to your circumstance.
Only in this way can you solve this problem.
I’m looking forward to hearing from you.
