Your paper should begin with one or two introductory paragraphs that concisely and artfully discuss the general themes of your paper. Each paragraph should have its own topic sentence, its own thesis statement, as it were. End your paper with a conclusion. This should not be a simple restatement of the introduction. Rather, it should tie up the main themes of the paper even as it takes your arguments one step further.
Conclusions are difficult to write, but a strong conclusion marks a good paper.
Vary your sentence structure. Short sentences render your prose choppy. I want to know who did what to whom employing the passive voice makes this task difficult. You must acknowledge the source of ideas and facts which you gained from your readings. I take plagiarism or making up sources very seriously.
