國中英語基測出現過 grade 的考題。

Dear Dad,

I know you are unhappy about the poor grades on my tests this semester. I'm sorry for that. I promise I will study harder next time. But Dad, please, could I study at home by myself? I don't want to go to the cram school any more. I don't think it can help me. I promise I won't spend so much time watching TV and playing computer games. I'll do my homework every day and use my time well to preview and review every lesson.

Let me try, Dad. I'm sure I'll do better.

Your son,

Fred
