3写作简单句的扩展.ppt

简单句的扩展; 五种基本句式是构成文章的基础。要想提高写作水平，还必须会写复合句。我们要在简单句的基础上充分利用形容词、副词、定语从句和状语从句等来充实句子。 1．由简单句到并列句，实现基本扩展 在两个或多个简单句之间加上and，or，but等并列连词，或加上分号，把简单句变成并列句，从而使句子的连贯性更强，表达也更为贴切、自然。如：;Tom is our monitor now.He came to our school last year. →Tom came to our school last year and he is our monitor now.(把意义松散的两个句子合为一体，句意连贯性更强了) →Tom came to our school last year；he is our monitor now.(通过标点符号，也能达到异曲同工之效) Tom is good at English.He doesn’t do well in Chinese. →Tom is good at English，but he doesn’t do well in Chinese. →Tom is good at English；he doesn’t do well in Chinese. Tom missed the bus.He wasn’t sorry for that.;→Tom missed the bus，but he wasn’t sorry for that. →Tom missed the bus；he wasn’t sorry for that，though. Tom does his homework in the classroom.He sometimes does his homework at home. →Tom does his homework either in the classroom or at home. →Tom usually does his homework in the classroom，or at home sometimes.;2．由简单句到复合句，实现过渡扩展 只要给一个简单句任意加上一个从句(尤其是定语从句和状语从句)，复合句即可生成，表达出更多或更复杂的意义，从而有效地避免简单句松散、单一的表达形式。如： The meeting came to an end. 我们试加一个定语从句：The meeting that they held in our classroom came to an end. 我们试加一个状语从句：When we arrived，the meeting come to an end. 或：The meeting came to an end though it was still early.;或：Before I could speak anything，the meeting came to an end. 如此等等，不胜枚举。只要我们善于扩充，适度添加单词、短语或从句，句子就会更富有表现力。 3．着意添加成分，实现高级扩展 如果我们给一个简单句着意添加一些附加成分，句子的扩展性则会更强。 我们以“他上学来晚了”为中心句，便可尝试添加附加信息：他昨晚熬夜了；他没赶上车；他没耽误第一节课；不然他就赶上第一节课了。这样，我们便会有以下句子：; He stayed up last night，so he came to school late. He came to school late because he stayed up late last night. He missed the bus，so he came to school late. He missed the bus，but he didn’t miss the first class. He missed the bus，or he wouldn’t have missed the first class.;4．运用修辞手法，实现自由扩展 只要有几个句子罗列出现，句与句之间便有一定的关系。如果我们想表达承接、转折、因果、递进等关系，扩展句子时，就可以根据语义自由选择恰当的关联词。 用于不同功能的这类词汇有： 并列：and，as well as，also，both...and等； 选择：or，either...or，neither...nor，otherwise等； 原因：because，for，as，since，owing to，due to等； 结果：so，therefore，thus，as a result等； 时间：when，before，later，fir
