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 really appreciate the opinion. I begin to be crazy about English when I was a little boy. And I got interested in foreign culture and custom in particular to meet my curiosity. I read English stories, listened to English songs and watched English films on every day, all of that even seemed to be the “meal” of my daily life. As the result, I always did very well in English exams.

    In a word, interesting is the key to success. Anyone who are interested in something will devote himself to them.

    Dear headmaster,

    I'm writing to tell you some problems at the campus. It is common that students are accustomed to have snacks and drinks after having sports.

    I'm worried that if students addicted to snacks and drinks, it will do great harm for their health. They need to take in all kind of nutrition. Therefore, snacks and drinks can't meet his need to grow up normally. On the other hand, it is easy that for students to get into a bad habit of spending money in buying such kind of things, which is the waste of money.

    In my opinion, students should have regularly meals. Meanwhile, we can eat fruits or drink milk to make sure that we can develop healthily.

Yours,

Li Hua

    Last month, I took part in a volunteer activity in a village. We start off by bus at 9 o'clock. After a three-hour drive, we saw the village surrounded by hills. It was very difficulty to drive on the rocky road, so we got on the bus and walked there. The villagers standing by road welcomed us warm.

    Cooked with those vegetable grown by the villagers, the lunch was tasted delicious. After lunch, we played games with the village children. Then, we visited an old man live alone on the hillside. We sang a few songs, what made him really happy.

    I think when doing volunteer work, you help others and you gain happy in return.
