倒装

【要点1】倒装分完全倒装（谓语整体提前）与部分倒装（只把助动词/情态动词提前，类似一般疑问句语序）。【要点2】否定副词开头必须部分倒装：never、seldom、hardly、rarely、little、not until、not only...but also、by no means 等置于句首时，如 Never have I seen such a scene。【要点3】only + 状语（副词、介词短语、状语从句）位于句首时部分倒装：Only in this way can we solve the problem；注意 only 修饰主语时不倒装。【要点4】so/neither/nor 开头表"也/也不"：So do I，Neither can she。【要点5】完全倒装：表方位的副词或介词短语开头（Here comes the bus；On the hill stands a temple），主语为代词时不倒装。【要点6】as 引导让步从句时表语提前：Young as he is, he knows a lot。虚拟条件句省略 if 时倒装：Had I known, Were I you, Should it rain。
