Possible version:
I am an 18-year old middle school student. I have been busy with my study and seldom helped my parents with the housework. Feeling quite sorry for that,I begin to think about what to do to help.
Last Sunday, when my parents went out shopping,I suddenly got an idea: why not give the rooms a thorough cleaning? Firstly I collected all the books,newspapers and other things scattered in the rooms and put them in place. Then I wiped the dust off all the furniture. After that,I swept and mopped the floors.
At this very moment,my parents came back and were quite surprised to see all the rooms tidy and floors shining. My mother gave me a hug and Icould see satisfaction in her eyes. Tired as I was,I never felt so happy.
