人教版新目标 Unit 4 Section B 3B的那个小作文怎么写?

Dear Bob,
I got my report card today.Well,I did OK this time.I was very glad to hear that my math teacher said that I was hard-working.And my Spanish teacher said that I was good at speaking.However,I still had some trouble in learning history and science.My history teacher said that I could do better,and my science teacher said that I was a lazy student.In a word,I think I need to study hard in the next semester.
Yours
Scott
