* 第12讲　巧扩妙展,文采无限——扩展句在写作中的应用 一、魔法导航 在写作中我们通常把用以支持主题句的句子称为支持句或扩展句。段落扩展句的写作是段落写作的“核心”,其质量高低将决定整段文章的成败。在段落扩展句的写作中要注意以下几个问题: 1.抓住一个中心,对扩展句精挑细选。 所有的扩展句都必须与主题句保持一致,都要为主题句服务。所有与主题句无关或关系不大的句子都要从扩展句中去掉。如: Quite a few things give rise to the traffic problem.In spite of the large-scale construction of roads and highways,there is still much room for improvement,because of the ever increasing number of cars these years.What’s worse,some drivers,cyclists and pedestrians do not think it vital to obey traffic rules. 【评析】　本段的主题句“Quite a few things give rise to the traffic problem.”点明了本段的中心思想:介绍导致交通问题的原因。下面的扩展句紧紧围绕中心句说明了两种具体原因,有力地支持了主题句。 2.选用合理的写作顺序,保持扩展句之间的连贯性。 扩展句不能杂乱无章地堆砌到一块,而是应该恰当运用合理的写作顺序(如时间、空间、逻辑等顺序)把各个扩展句有机地组织起来,使其浑然一体。 例1:运用空间顺序组织扩展句。如: Our library is in the center of the school.There’s a beautiful garden in front of it and our classroom building is right behind it. 例2:利用时间或逻辑顺序组织扩展句。如: When the craftsman came into the classroom,we gave him a warm welcome and two boys helped him with the tool box.First,he showed us the basic steps and skills of making dough figurines.We stood around him and watched attentively. Then we started to have a try ourselves.The old man walked around and helped us patiently.Finally,we put the figurines we made on the table and took pictures with the old craftsman.Looking at the figurines,we were all very excited. 【评析】　本段利用时间顺序组织写作,向老艺人学习捏面人的过程跃然纸上,读后令人印象深刻。 3.恰当议论,锦上添花。 在扩展句的写作中根据实际需要对某些扩展句进行恰当的点评或做进一步的阐释不但可以丰富段落内容,而且还可以起到深化主题、画龙点睛的作用。如: When I am faced with difficulties,I usually choose to refer to relevant learning materials or web pages.In this way,I can not only work them out but also improve my ability to overcome difficulties all by myself. 4.注重结构,段落层次分明。 在段落扩展句的写作中可以采用有形或无形的“三节式”扩展模式,即 “主题句+扩展句+总结句”的结构。如: In fact,traffic rules are part of the rules and regulations closely related to public order.Without them,people could not enjoy harmony or the country would be in chaos.But rules alone don’t secure an orderly society.It is the people who o
