When I was a middle school student, I had to learn manysubjects every day. Of all the subjects, I was poor at maths, so I didn't wantto do maths homework at all.

One evening, when I came back from school, I said to mymother," I don't want to learn maths, I don't know what the teacher talksabout. Maths is too difficult for me." My mother said, " Don't bedisappointed, my boy. I can be your maths teacher. "I felt very surprised.

Every day after school, Mum and I studied together for anhour. I was fond of my mother's "class" and became interested in(对……感兴趣）it little bylittle.

One night, when I wanted to go to bed, I found my mother wasstill doing something at the desk. I opened the door and saw her studying mathson the Internet. I knew why my mother was good at maths.

A mother can do everything for her children. As children, wemust thank our mothers.
