1、在一篇短文中，如果句子结构要么是“主谓宾”，要么是“主系表”，则显得很单调，读起来乏味。若对简单句进行一下转换，使其主语灵活，句子结构活泼，则给人的感觉就大不一样。简单句之间的转换有下面三种方法：一、转换句子结构例 李东住在南方。他的家乡经常下雨。一般：Li Dong lives in the south.It often rains in his hometown.较好：Li Dong is from the south.There is a lot of rain in his hometown.分析“一般表达”中的两个句子均是“主谓”结构，比较单调。把它们分别转换为“主系表”结构和the

5、as my friend that I met in the street yesterday.(强调宾语)It was in the street that I met my friend yesterday.(强调地点状语)It was yesterday that I met my friend in the street.(强调时间状语)注意：强调时间和地点时，不能用when或where，要用that。三、转换词语例 杰克是我们学校的学生。他学习特别努力。一般：Jack studies in our school.He studies very hard.较好：Jack studies
6、 in our school.He works hard at his lessons.分析“一般表达”中的谓语重复使用study，显得呆板。词语转换后，句子就“活”起来了，读起来有滋有味。例 妈妈匆匆忙忙去上班，连早餐都没吃。一般：Mother went to work in a hurry.She didnt have breakfast.较好：Mother went to work in a hurry without having breakfast.分析“一般表达”中的两个简单句之间关系松散，使用介词短语进行转换后使句子内部结构紧凑，读起来一气呵成。.简单句转换(转换词语或句型)1有
