A Survey About Weekend Activities
The students don¡¯t go to school on Saturdays and Sundays. Well, what do they do on weekends?¡¡
¡¾´ð°¸¡¿The students don't go to school on Saturdays and Sundays. Well, what do they do on weekends? The other day, I made a survey of how the students spend their weekends. I find that 40% of the students take weekend classes. About 25% of them like to chat online or play computer games. 20% of them prefer to watch TV or listen to music, while 10% of them help their parents do chores. Only a small number of them play sports.
I don't think it's a good idea to take weekend classes. And students shouldn't spend too much time watching TV, chatting online or playing computer games. They should do more sports, learn to develop interests and try to do some chores.
