【正确答案】 C

【答案解析】In order to write a thorough essay it's important that you are proficient at a number of skills. The first one is analysis skill, you must analyze your topic thoroughly and make research to find evidence to prove your idea before you start writing to assure you have a strong thesis, the right main sections in the body, and at least a general idea of your possible conclusions on the topic. The second is reading skill, when you write a proper essay, "wide reading" is important— you have to read a lot before narrowing the concepts down for your paper. It is helpful to know exactly where to look for valid references to support your main topic and how to pinpoint the most important information to be involved in your paper. Then the editing skills, after writing the paper, you need to go back over the paper with a pair of "fresh eyes" and correct spelling, grammar, and content issues. The last is formatting skill. Since essays are commonly written in word processing programs, you need to be proficient when it comes to formatting your essay document in these computer programs. Most instructors will require you to write the essay in MLA format. You must also be familiar with the proper format of your citations page, which contains a listing of your references.
