托福写作考试中，议论文是最常见的一种题型，那么这类题型该如何安排托福作文格式呢?下面小编为大家介绍一下议论文的托福作文格式，希望能帮助大家把握议论文的写作思路。
　　在应试型议论文写作中，通常遵循引言段-主体段-结论段的“三步曲”。主题段落提供了论证观点的理由，是整个文章的主体，占分最大。一篇满分作文必须论据充分。
　　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.
　　(每个主体段都必须有一个明确的主题句)
　　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.
　　(支持句必须围绕主题句展开)
　　新托福满分作文(5分)也要求“is well organized and well developed, using clearly appropriate explanations, exemplifications, and/or details”，同样必须通过主体段落发展来实现。一般来说，一篇议论文必须包含至少两个主体段。每个主体段都必须有明确的主题句“topic sentence”和若干支持句“supporting sentences”。他们共同组成文章的理由段，对全文的论点提供理由支持。
