托福寫作考試中，議論文是最常見的一種題型，那么這類題型該如何安排托福作文格式呢?下面小編為大家介紹一下議論文的托福作文格式，希望能幫助大家把握議論文的寫作思路。
　　在應試型議論文寫作中，通常遵循引言段-主體段-結論段的“三步曲”。主題段落提供了論證觀點的理由，是整個文章的主體，占分最大。一篇滿分作文必須論據充分。
　　1.Write a topic sentence for each paragraph you plan to write. Each topic sentence should relate to your thesis statement and introduce what the paragraph will be about. If you find that the topics you want to discuss do not support the thesis statement you have written, revise your thesis statement or reconsider your topic sentences.
　　(每個主體段都必須有一個明確的主題句)
　　2.Write ideas that support your topic sentences. The topic sentence for each paragraph tells the reader what the paragraph will be about. The ideas stated in the rest of the paragraph should all relate to the topic sentence.
　　(支持句必須圍繞主題句展開)
　　新托福滿分作文(5分)也要求“is well organized and well developed, using clearly appropriate explanations, exemplifications, and/or details”，同樣必須通過主體段落發展來實現。一般來說，一篇議論文必須包含至少兩個主體段。每個主體段都必須有明確的主題句“topic sentence”和若干支持句“supporting sentences”。他們共同組成文章的理由段，對全文的論點提供理由支持。
