Last Monday we asked our students about how often they do the housework in Beishan Middle School. Here are the results.
Most students do the housework twice or three times a week. They often clean their rooms. Some students do the housework five times a week. They often clean the floor(地板). Some students help their parents on the farm. They think their parents are too busy, so they help them.
The results for “wash clothes” are interesting. Some students wash clothes once or twice a week. They often wash clothes on Saturdays or Sundays. Some students wash clothes three to four times a week. They only wash their own（自己的） clothes. But most students wash their clothes once a week. And they wash clothes on Sundays.
