So you need something like this, I am going to try to give a format and you can fill in the blanks:
What makes the American Dream so real in the eyes of Americans everwhere? What is the desired goal of each and every USA citizen who believes in this idealistic goal? In (insert author name) Great Gatsby, the author portrays his ides of the American dream through (insert characters or plot of story here). The story is about (give a one sentence explanation of the story, be sure their are no run on sentences.) (Add here what you think the story's conflict is in one or two sentences.) While the Author of the book gibes a clear understanding of the American dream, I (here you add your own take on what you believe the American dream. Make sure you add the fact of wether you support the authors take on the American dream or not!)
Your ending sentence should be something that hooks your audience into hour first paragraph, and done! Depending on why type of essay your writing, you may want to tweak some of the sentences around, but that is pretty much it!
The relative pronoun "that" introduces the relative clause 'that lives in Jim's room'.
