37、 38391.1 段落的写作 o 我们知道，段落是文章的重要组成部分。文章往往由一个或几个段落组成，段落写作的好坏会直接影响文章的表达和思想的交流。因此，掌握段落的写作要领是学习文章写作的第一步。401.1.1 段落的结构 o 段落是由若干个句子组成的，用来说明一个中心或者从一个角度对文章的主题进行阐述。因此，段落不是句子的任意堆砌，而是符合一定的模式，具有某些基本特征及遵循一定的发展方法的。段落，尤其是说明文和议论文的段落，大多由三部分组成：主题句、扩展句（或发展句）和结尾句。 o 4142（1）主题句o 段落的主题（topic）是一个段落阐述或说明的对象。主题句（topic sentenc

38、e/ts）是提出段落的主题、概括段落中心思想或反映作者写作意图的一个概括性句子。它是段落发展的依据并且规定段落的发展方法。43o 主题句的特点主题句的特点：1） 段落主题句只能有一个主题。该主题必须紧扣文章的中心思想，把段落内容限定在文章内容的一个方面；2） 段落主题句必须具备一个主导思想，即段落主题句中必须包含一个等待发展的思想，以确定段落的发展方法；3） 段落主题句必须具有一定的限定性。其限定内容有助于段落的铺开和抒发，避免段落在展开过程中偏离主题方向。44o 主题句的构成主题句的构成：o 主题句常由主题和作者的观点两部分组成，作者的观点就是我们常说的关键词，反映了该段内容的支配思想（co

39、ntrolling idea）。o 主题句的位置主题句的位置：o 主题句大多位于段首，但也有位于段中和段尾的。对初学写作的人来说，应首先学习段首主题句的写法。我们先来看两个主题句： 45topic: city life1. topic sentence: it is more convenient (controlling idea) for people to live in city (topic) than in countryside.这个主题句的支配思想(more convenient)很好地限定了主题(city life)的写作范围; 具体地说出生活在城市的种种便利.46topic

40、: air travel2. topic sentence: air travel (topic) has several advantages (controlling idea) compared with other means of transportation. 这个主题句明确规定了本段将阐述乘飞机旅行的几个优点。从上面的例子可以看出，主题句能限制主题的范围以及提示主题的发展方法。47 o 1) 主题句不能太笼统主题句不能太笼统topic: our school campustopic sentence: i love our school campus.这个主题句没有限制一个合适的

41、范围,包括的内容面太宽,不好下笔，因此可改为: i love our school campus for several reasons.48o 2) 主题句涉及的面也不能太窄主题句涉及的面也不能太窄,否则就没有否则就没有展开讨论的余地展开讨论的余地。topic: college lifetopic sentence: i go to college to make friends.此类涉及面太窄的主题句就不好进一步发挥,这一主题句可改为: i go to college for several reasons.49o 3) 主题句不仅限于一种形式主题句不仅限于一种形式,根据不同的主题根据不同

42、的主题,可以可以有各种各样的主题句有各种各样的主题句。o 例如:主题句直接点明某事物的作用或优点。topic: solar energytopic sentence: solar energy can contribute to our future energy supply主题句指出人们对某事物的不同观点。topic: opportunitytopic sentence: it differs from person to person as to the view of opportunity.50（2）扩展句）扩展句o 扩展句或称发展句（developing sentence/ds或developer）、支持句（supporting sentence），是用来发展、证明或支持段落主题思想的句子。o 扩展句可分为两种：主要辅助（major support）和次要辅助（minor support）。o 主要辅助指在意义上与其他扩展句相独立，从各自不同的角度对段落主题加以深化、阐述的句子。次要辅助是隶属于
