Dear Sir，

Thank you for your offer of invite me to the summer English course in your school. As for your choice between the two courses, I prefer the four-week course for 60 hours of study. Because of this would allow me more times to do some travelling and make a few new friends either. Of all the subjects I'm learning at school, I like English best. I had been learning English for 6 years but my spoken English remains poorly. So I hope to take this chance to improve it. If is possible, I'd like to stay with a family for a couple of days in order I can know some customs in England. I believe I will have wonderful time this summer.

Yours truly,

Li Hua

    I prefer my English classes to be taught in English only. What we all know, a good learning environment is of greatly importance if we want to study English well. Classes teaching in English provide students for a better environment. When English is an only language in class, students will have more opportunity to practise listening and speaking. However, there were problems with this method. Sometimes we may find difficult to follow the teacher and some slow learners may even give up learn English. In spite of these difficulties, but I believe practice makes perfect. With enough practice, we can overcome the difficulties and benefit from English classes in the long run.
