Last Saturday I cooked supper for my family. The whole morning, I was on the Net, studying what to make delicious food out. After lunch, I went to the market and bought some vegetables and pork. Back home, I began washed the pork and cut them into cubes. The pork should be cooked firstly because it would take a long time. When the pork is being boiled, I continued toprepare the other dishes. After two hour of hard work, three dishes and a big bowl soup were on the dinner table. Mom and Dad all congratulated me. They said it was the best supper they have ever had!
