Dear Lihua,
I'm sorry to hear that you have failed in the English exam again and your parents are mad at you.Well,please calm down and don't be upset anymore.You see,it's not surprising that parents and kids have different ideas on somethings.It also shows that English is very important.I have been learning English for 11 years.So I have some good ideas that may help.First,you should take some English notes while having English classes.You also need to review your notebook after school.Second,why not watch some English programs and listen to some English songs?This is a great way to improve your English.By the way,you'd beeter write a letter to your parents,so that they can understand you at once.
Yours
Jim
