与议论文的整体结构布置相类似，在段落的写作中我们也用“三明治”结构来进行写作，即把段落分为主题句(Topic Sentence)，支持部分(Supporting Sentences)和结尾句部分(Concluding Sentences)。(注意：并不是每个段落都一定要有结尾句，重要地是要让这个段落自然地结束，不能给读者留下话还没有说完的感觉。)段落结构如下图如示：

　　PARAGRAPH

　　Topic Sentence

　　Supporting Sentences

　　Concluding Sentence

接下来我们通过实例来了解主题句，支持句与总结句的布置。比如：

1. Topic Sentence: First of all, the fact is that ready-made meals are not usually that good for us。

Supporting Sentences: They contain high levels of salt and sugar, not to mention harmful preservatives and artificial colorants。

Concluding Sentence: Therefore, a diet that is exclusively made up of such food is bound to be unhealthy。

2. Topic sentence: Teenagers find many ways to drive their parents crazy。

Supporting Sentence 1: First, they may dye their hair purple or they may shave their heads bald. They may also shred their new and expensive jeans and sit hours after hours in front of computers playing games or chatting with someone they never see。

Supporting Sentence 2: In addition, they spend hours windowing-shopping and on the phone. They have time to watch TV, but they do not have time to do their homework。

Supporting Sentence 3: Also, they are always too busy to clean their rooms, but they are never too busy to hang around in the streets。

Concluding Sentence: It is hard to be a teenager, but it is even harder to be parent of one。

3. Topic Sentence: In the second place, corporal punishment is by no means a desirable way of education a child。

Supporting Sentence 1: Numerous studies have shown that it does far more harm than good to children in their mental as well as physical development。

Supporting Sentence 2: For example, corporal punishment can give a child a sense of being treated unfairly, making him rebellious。

Concluding Sentence: This will be detrimental to the molding of the child’s character, and therefore should be avoided。

通过以上例子，我们可以清楚地把握雅思议论文结构(三明治结构)，并可以通过练习一些雅思作文题目加以模仿，使得所写的文章结构良好，内容清晰、易读。良好的结构，清晰易读的内容也是好作文的一些特点。另外，朗阁雅思专家建议考生在详细地学会如何发展段落以及组织整篇文章之后，可以把更多的时间放在对一系列常考写作话题“脑力震荡”上，即尽量地准备更多话题的相关地ideas来组织论据。
