Dear Mike,

    How are you doing these days?

    Aimed at providing a platform there students can have a chance to exchange and make use of their books, the annual campus books fair will soon held in our school. The fair will attract a huge crowd from the entirely school, who are to sell, purchase but exchange their second-hand books with their peers.

    As a regular visitor, I've found myself increasingly drawing by the fair. For one thing, the fair exhibits books of hundreds of type on diverse topics, motivating us to further develop their reading habits and help to broaden our horizons. For other, most books are sold at a low price than what the bookstores offer.

    Please let me to know if you have any suggestions on how to host such a book fair better.

Dear Sir,

    Thank you for invite me to the summer English course in your school. As for your choice between the two courses, I prefer the four-week course because of this will allow me more time to do some traveling but make a few new friends. Of all the subject I'm learning at school, I like English better. I had been learning English for eleven years but my spoken English remains poorly. Therefore, I really hope to take this chance to improve it. If possible, I'd like to stay with a family for a couple of days in order that I can know some customs in England, what I'm particularly interested in. I believe I will have wonderful time this summer.

Yours truly,

Li Hua

    I was used to feel sleepy in class and couldn't focus on the lessons the teachers give. As a result, not only did I do bad in my studies, but also my health went from bad to worse, about which I was often scolded by my parents. I was also worried my situation. About half a year ago, followed the head teacher's advice, I began to take part in some sport activities. I had kept on playing basketball for 45 minutes and so every day till today. Now my health has been greatly improved, so at the same time, I've made good progress in all my lessons. Physical exercise has changed me into an entire new person!

    Jack was a excellent student at school. Whatever he did, he is always the best one in class. He could get full marks every time even he didn't listen to the teacher. Some people found it surprised that he was always ready to help the others with a smile. He helped his classmates with his homework; he helped the teachers answer the difficult questions risen by the students; he was good at ball games…In the whole, he was a perfect boy. Everybody liked him. He lived a peacefully life until one day when he got up he finds a gray hair on his head.

    Chinese Dream is made up of ordinary people dreams. If someone asks me what my Chinese dream is, I will answer it without think twice: to be a good doctor. The reason why I want to be a doctor is because I want to save as more lives as I can. When I was young, I got serious injured in a terrible accident. Thanks to the doctors' efforts, I brought back to life. Since then, to be a good doctor had always been an encouragement to me. To make sure of that my dream can be realized, I have been studying hard to be admitted into the good medical college. Only in this way can I achieve my goals.
