假如你是李华。你的朋友Tom给你写信诉说心中的烦恼：自己每天忙于学习，朋友很少，感觉很孤独，尽管自己也想改变这种状况，但不知该如何去做。现在请你写封回信，给他提供一些建议。内容要点如下：
1. 羞涩、不自信可能是问题所在；
2. 微笑拉近与同学的距离；
3. 多与同学单独交流。
注意：1. 词数100左右；开头已给出，不计入总词数。
2. 可以适当增加细节，以使行文连贯。
Dear Tom,
From your letter I know that you spend most of your time studying and hardly talk to your classmates. You feel quite lonely and wish to have good friends!
                                                                                        
                                                                                        
                                                                                        
                                                                                        
                                                                                        
                                                                                        
Yours,
Li Hua
