垂悬结构是种错误的句法,应该避开
下面是三种常见的垂悬结构及其改正方法:⒈垂悬分词或分词短语,如:①Climbingupthehill,severalboarswereseen
这句子里的现在分词短语(presentparticipialphrase)修饰主语“severalboars”是错的;改正方法有二:(a)确定是逻辑主语,使句子变成“Climbingupthehill,theexplorerssawseveralboars
”(b)把现在分词短语扩大为副词分句(也称状语从句):“Whentheexplorersclimbedupthehill,theysawseveralboars/severalboarswereseen
”⒉垂悬副词短语,如:Afterputtingashrimponthehook,thefishbegantobite
这句的副词短语(adverbphrase)和主语“thefish”有什么逻辑关系呢
真正的逻辑主语应该是“thefisherman”或“theangler”才对
改正方法:(a)Afterputtingashrimponthehook,thefishermanfoundthatthefishbegantobite
(b)Afterthefishermanhadputa下载后可任意编辑shrimponthehook,thefishbegantobite
⒊垂悬不定式动词短语,如:Towritewell,alotofpracticeisneeded
