大學d essay應該點寫ga?!

Since you are a university student, I guess it is ok for me to answer your question in English.
Studying literature in a secondary school is very different from studying social work in a university. When you write an essay of university standard, not only you need to outline your knowledge of the subject, you also need to demonstrate some application and originality. Application means applying the book knowledge to everyday life. Originality refers to giving recommendation on any shortcomings.
I think you should ask your professor what exactly is required in the essay. He/She is the only person who assesses your essay and who can help you. Make an appointment to consult him/her. Every professor will be happy to talk to students who want to learn.
