1、写作点拨系列（三）段落写作之主题句和支持句,【核心点拨】一、主题句 概括段落的主要内容，确定段落的主题，限定该主题在本段落详细讨论的范围，是整个段落的纲领，此句即为主题句。围绕主题句，作者通过列举事实、提供例证、描写细节、说明理由等逐步展开段落。,1.主题句的位置(1)主题句通常置于段落开头，开门见山摆出问题，随之辅以细说。其作用是便于读者迅速地把握主题，抓住段落的中心思想。此为演绎法(deduction)，便于初学者仿效。Nowadays,every student pays enough attention to study habit because of its importance.
2、As for me,I have three ways to improve my study habit.段落第一句是主题句，道出了全段的中心思想学习习惯。study habit是关键词。,(2)主题句也常置于段落末尾。作者先不说出本段的中心思想，一直留到最后才披露。这可以给读者设置一种悬念，迫切想要读下去，同时给读者的印象也特别深刻。放在段末的主题句，通常还有对前面所述作总结的作用。这可称为归纳法(induction)。As the saying goes,genius is the product of the loneliness.Einstein is a good example.

4、ld be easier to taste the real life.最后一个段落为总结性段落，最后一句为结论性主题句，点出了本篇文章作者写作的目的就是让人们学会享受孤独，品尝真正的人生。(3)有时主题句会出现在段落中间，也有时主题句含而不露，隐藏在全段的字里行间。,2.主题句的写法 主题句的句子结构和思想内容必须完整、清楚、具体，不能模棱两可、空泛。要避免不完整(incomplete)、不清楚(unclear)、过于笼统(general)，如作文题目是The Advantages of Travel(旅行的好处)。试比较其中一段的主题句，前三种写法均不可取。不完整 Enjoy the be
