2017年12月英语四级语法知识：特殊从句的倒装

　　特殊从句的倒装

　　1. 让步从句的倒装

　　(1) as引导让步状语从句，必须采用倒装结构，但不是主谓倒装，而是将被强调的内容置于句首。例如：Much as I have traveled, I have never seen anyone to equal her, in thoroughness, whatever the job.

　　(2) 出现在句型be+主语+其他中。例如：Our civilization has accumulated an incredible amount of knowledge—be it scientific or artistic. The business of each day, be it selling goods or shipping them, went quite smoothly. Come what may, I’ll be on your side.

　　2. 比较从句的倒装

　　as, than引导的比较从句中，如果主语是名词短语且较长，经常采用倒装结构(不倒装也可以)。注意：这种结构主语一般为名词，如果是代词则不倒装。

　　例如：Hydrogen burns much more cleanly than do other fuels and is easy to produce. Reading is to the mind as is exercise to the body.
