主题句包括主题词和关键词。如果说前者涉及要说什么的问题，后者涉及的则是限定应写的内容、范围。 Smoking is harmful to health. Getting rid of the smoking habit is not easy. In order to protect non-smokers from becoming smokers, measures must be taken to reduce the appeal of smoking. 紧紧把握主题句中关键词的导向和制约作用，是作文写作成功的关键因素之一。 扩展句包括主要扩展句和次要扩展句。前者是为了对主题句中表示主要思想的关键词进行直接、明确的说明，后者则是为了说明它的主要扩展句。需要注意的是，并非每个自然段都需要包含主要扩展句和次要扩展句。 例如：
（主题句）I don’t teach because teaching is not easy for me.
（主要扩展句1）Teaching is the most difficult of the various ways I have attempted to earn my living: mechanic, carpenter, writer.
（主要扩展句2）For me, teaching is a red-eye, sweaty-palm, sinking-stomach profession.
（次要扩展句1）Red-eye, because I never feel ready to teach no matter how late I stay up preparing.
（次要扩展句2）Sweaty-palm, because I’m always nervous before I enter the classroom, sure that I will be found out for the fool that I am.
（次要扩展句3）Sinking stomach, because I leave the classroom an hour later convinced that I was even more boring than usual.
当然，上面列举的各种支撑句也不一定一次性全用上，而是要根据写作的主题来取舍。
