     It's Monday today. Oh, I don't like Monday because I'll have to go back to school again after the

weekend. Tuesday is not so bad. I usually play tennis with my friends after school. On Wednesday

evening I don't go out. I stay at home and do my homework. I like Thursday because the next day is

Friday. I always go out on Friday-maybe to the movie.

      I love the weekend. On Saturdays I stay in bed until (直到) lunchtime, and I sometimes go to the

shops in the afternoon. In the evening I go to a club---there are good bands every Saturday. Then on

Sundays I go to my friend's house or she comes to my house. I usually visit my grandmother for an hour

in the afternoon. Then the weekend is over (结束)  and it's Monday. . . and I feel bad again!
