15、the Topic Sentence 主题句(Topic Sentence):说明段落的中心思想或段落主题的句子,是段落展开的依据.它由两部分组成,即主题(topic)和支配思想(controlling idea)构成.支配思想规定段落发展的脉络,限制主题覆盖的范围.主题句起到概括段落中心思想作用,它往往是一个概括性的句子.如果太宽,太笼统,则超出一段文章的范围,无法把问题说清楚.通常在写作时对自己提一个what,who,when,why,how这样的问题.牢记主题的三个条件:A topic sentence is a complete sentence.Driving on freeways

27、特点 1)段落的整体性或一致性(Unity):一段文章只能讨论一个中心思想,文章中所有的细节都要与主题相关,利于说明这个中心思想.Unity means that you discuss only one main idea in a paragraph.The main idea is stated in the topic sentence,and then each supporting sentence develops that idea.2)连贯性(Coherence):各句子的安排必须符合一定的顺序和条理:句子与句子之间衔接要紧密,过度要流畅 Coherence means th

28、at your paragraph is easy to read and understand because your supporting sentences are in logical order and your ideas are connected by the use of appropriate transition signals.The Coherence and Continuity of a Paragraph transitions and connectors 可以通过俩列两种手段来实现(1)内容的安排方法-按一定的逻辑顺序(时间/空间/一般与具体/重要与非重要

29、).所谓的一般与具体的顺序主要是指段落的整体框架.通常,主题句在段首的段落按“一般到具体”,即演绎顺序写成;主题句在段尾,则是按“具体到一般”,即归纳顺序写成.重要与非重要的顺序是针对段落内部细节排列次序而言.从非重要到重要的顺序是重要性递增;从重要到非重要是重要性递减。(2)使用过度性词语-句与句之间使用适当的过渡性词语,起“启,承,转,合”的作用.引导读者全面了解句子见的逻辑,准确地理解段落的思想.3 段落的展开手法段落的展开手法 1)时间顺序法:按事物发生的时间先后为线索展开段落,主要是叙述一件事物的经过.主要用于故事,自传等.动词常用过去时 E.g.In my thirty years
