倒装结构

 　　同学们很容易混淆的是全部倒装与部分倒装。如何区分之，编个顺口溜：副(adv.)介(prep.)提前全倒装，其它句式部分倒;否定提前倒助动，让步状语倒表语;复合句式倒主句，不倒装的属特殊。

　　下面举例说明：

　　A、Here comes the bus.(副词提前，全倒装)

　　B、Here he comes.(代词作主语，不倒装)

　　C、In front of the house lies a garden.(介词短语提前，全倒装)

　　D、Never shall I do this again.(否定词提前，部分倒装)

　　E、Young as he is ,he knows a lot.(让步状语从句，表语倒装)

　　F、Only when he told me did I realize what trouble he was in.(only 修饰状语，主句倒装)

　　G、Only he can save the patient.(only修饰主语.不倒装)

　　H、Not only will help be given to people,but also medical treatment will be provided¹.(否定词提前，部分倒装)

　　I、Not only he but also we like sports.(连接两个主语，不倒装)
