Understanding is important for us to study.
One day,I had a fight with my parents.They thought my test was very bad.But I tried my best to do it.My father said:"If you try your best,then you should be careful."
In our study life,we should understand the difficult problems,then we will do better than last time. Tor example,talk with your teacher ,they will tell you how to do it.
I think I will become better and better.And understanding is very important.
