| Dear Annie, Thank you 1 your letter. I'm glad you like your school. I go to school from Monday 2 Friday. We 3 four classes in the morning and two classes in the afternoon. We have many things 4 after Class. On Monday and Wednesday afternoon we have 5 . On Tuesday afternoon some of 6 have a 7 class and on Thursday afternoon some have a drawing class. On Friday afternoon we practice 8 English. My Chinese friends would like 9 with me in English. They think I am like an English teacher. Isn't it great? On Saturdays and Sundays I 10 go to school. Very often I go to the parks and have a good time with my family there. Yours, Henry | ||||
