Reading and writing is an article in which a mother is teaching her children to do their homework.

One day, Xiao Ming came home from school and came to his desk. He took out his exercise book and turned on the lamp.

I did my homework carefully.

After writing for a period of time, he found that he couldn't do a problem. After scratching his head for a long time, he would always do it.

There is no answer. At the right moment, my mother came over with a cup of hot tea and sat down beside him gently.

Besides. Xiao Ming frowned and asked his mother, "Mom, how to do this problem? Can you teach me? "

Mom smiled and said, "Have you thought about it yourself?" "My head is dizzy, quick teach.

Me! "Mom touched Xiao Ming's head, looked at the topic and explained patiently.

Xiao Ming finally figured it out and smiled!
