When you write any essay (and TOEFL is not an exception), it must have not only sense but also the structure which is easy to see and understand for any reader of your essay. Let’s look at what makes up the structure of an essay for the TOEFL.
* Intro. It helps to build the first impression of the essay, so it is worth special attention. Start with an interesting and nonstandard ideas that will make a reader think (sometimes citations can help). Next most important thing is the thesis. It is a statement, which outlines what you will say in your essay, as well as your views on this issue. Usually this is the last sentence of the first paragraph. In the introduction, there should be no dates, places, etc. – all the facts will go into the main part. The task of intro is to briefly explain to the reader what you will say next, and motivate him to read your arguments.
* The main part. It reveals and substantiates the thesis that you should do in two or three paragraphs (for more you have hardly enough time). Each paragraph begins with justifying the sentence, which states the main idea of this paragraph, which, in turn, is the opening idea, stated in the thesis. Next you need to provide clear and concrete arguments to substantiate your claim, and justifying the proposal of this paragraph. Use as much as possible dates, facts, names of people, organizations, events, etc. At the end of the paragraph you need to logically move to the next paragraph and the following statement.
* The final part. It is often neglected, because, firstly, one may not have time, and secondly, people just do not know what else to say, because like everything is already set forth in the preamble and the main part. But do not forget the conclusion, as it gives your essay integrity and completeness. To write it, re-read the introduction and the first sentence of each paragraph. This will refresh your memory and help you understand what must be said in conclusion. Rephrase your thesis, do not repeat it. Complete essay with general suggestions. Do not give in conclusion the new information and do not make it too long, especially considering that you are very limited in time.
