Dear…,
     I haven't heard from you for a long time. How are you?
     I have just finished the exams. Now I am glad I have time to write to you. Our teacher tells us that China
is a large country. It has the largest population in the world. It is very far from the USA. It is on the other
side of the world. Now the sun is shining brightly while I am writing to you. But perhaps you are sleeping
in the dark night. How interesting it is! I'm becoming more interested in China. I wish to know more about
your life. Could you tell me what kind of food you often have for meals? Please write me soon!
     Best wishes to you!
                                                                                                                                               yours,
                                                                                                                                               Catherine
