Important
　　I used to be a lazy boy.I had never doneany housework before.But now everything has changed.On the first day of mysummer vacation,I found mum was really busy and tired.I felt sorry.
　　So I did some washing for her.I washedmany clothes,including my own stockings and trousers.I washed and washed,andwhen my classmates called me to play football,I paid no attention to them.Ithought mum and dad did a lot to bring me up,and I should do something forthem.I could share housework with them.When mum saw what I was doing,shepraised me greatly.I felt very happy and encouraged.
