Dear Zhang Han,

    Thanks for your e-mail. Your school life is very interesting. I hope I can go and visit you soon.

Now I would like to tell you something about my school life in England.    

     In England, the school day is from Monday to Friday. It usually begins at nine o'clock. First, we go

to our class teacher for registration (登记). Then we go to lessons. Each lesson usually lasts for forty-five minutes. There is a break about twenty minutes in the morning, During the break we can buy food from

the store. Some students have lunch in the school dining hall and others bring sandwiches or go home.

Students have to wear school uniforms. Lessons are over at 3:30 p.m. and then there are usually a lot of

activities,for example, sports and music clubs. I know Chinese students usually have a lot of homework.

We have homework, too, but not much. Tell me something about you and your friends.    

                                                                                                                                         Yours,

                                                                                                                                          Kevin
