I believe parents are the best teachers. I make this argument for two perspectives reasons; children spending spend more time with their parents than with school teachers, and school teachers has have a lot of students.

First, teachers cannot supervise children well. In society, there are very dangerous things for them. Children have suffered from drag drugs, alcohol, and smoking. Teachers cannot defend them from those dangers. In other words, parents can focus on them their children and can supervise them. So, they always can supervise children. For example, when I was a junior high school student, some other students broke a the rules. The teachers could not supervise them perfectly. In addition, their parents could not take care of their children’s behavior. However, my parents always supervised me and taught me what is bad to do right from wrong. For Because of my parent’s help, I also could defend myself from those dangerous by myself.

Second, teachers cannot take care of all their students very well. They are professional about Their job is teaching subjects. But since there are so many students, they cannot focus on the students who don’t understand class. Their parents should teach their children about subjects they cannot understand.
For instance, in my childhood, my parents often taught me math and Japanese. I was not good at Japanese. I could not follow my Japanese class. My parents helped me improve my Japanese. Now, I major in Japanese history in at my university. While Meanwhile, my friends could not take get good scores in math. His parents worked hard and didn’t teach him math. In As a result, he could not go to the high school that he wanted to go to.

In conclusion, I think parents are the best teachers for those three these two reasons.
