正常语序：主语＋be＋so＋adj.＋ 句子

倒装语序：So＋adj.＋be＋ 主语＋that＋句子

举例

a. She was injured so badly that he had to be sent to the hospital.

So badly was she injured that she had to be sent to the hospital.

b. The novel was s搜趣网o boring that he gave up reading it half way through.

 So boring was the novel that he gave up reading it half way through.

应用：在议论文写作时，表达“...太...以至于...”的情况不胜枚举。比如我们论述网络的负面影响时，可以写到：so attractive are video games that students fail to concentrate on their academic tasks. (电脑游戏太吸引人使得学生不能专心于学术活动)

As/though置于句首引导的让步状语从句可以倒装

最常用的情况

形容词＋as/though＋主语＋系动词，主句

举例：Great as the n搜趣网umber of such employees is, they only constitutea small proportion of the entire population. (虽然这些雇员数量很大，但是他们在总人口中只占很小的比重)

在议论文写作中，呈现转折关系的两句话几乎是任何一篇文章都不可避免的，如果能够掌握由as 或though引导的让步状语从句表达句间转折关系， 从而在文章中构造一个倒装结构，定将成为全文语言表达的一处亮点。
