so,such倒装句

so,such倒装句

若将so+adj. / adv. 置于句首，则其后的主句要用部分倒装。如：

So cold was the weather that we had to stay at home.

天气太冷，我们只好呆在家里。

So much did they eat that they could not move for the next hour.

他们吃得太多了，一个小时都动弹不得。

So loudly did he speak that even people in the next room could hear him.

他讲话声音那么大，隔壁屋里的人都听得见。

So fast does light travel that we can hardly imagine its speed.

光速很快，我们几乎没法像它的速度。

So sudden was the attack that we had no time to escape.

袭击来得非常突然，我们来不及逃跑。

类似地，当such…that…结构的such…置于句首时，such后的句子也要使用部分倒装。如：

Such a nice man did he seem that we all believe him.

他像个很和蔼的人，所以我们都喜欢他。

当“so/such ... that ...”结构中的so, such连同它所直接修饰的成分共同位于句首表示强调时，主句要进行倒装(that后面的结果状语从句不倒装)。

例如：

So angry was he that he couldn’t speak.

他愤怒得一句话也说不出来。(so与作表语的形容词放于句首，主句呈现全部倒装的形式)

So fast does he run that he is far ahead of others.

他跑得如此快，以至于远远领先于其他人。(so与修饰谓语run的副词fast放于句首，主句呈现部分倒装的形式)

To such an extent do the parents love their son that they have tried to satisfy every demand of his.

父母俩爱子爱到了如此程度，以至于尽量满足他的任何要求。(to such 放于句首，主句呈现部分倒装的形式)

［考题1］So difficult ____ it to work out the problem that I decided to ask Tom for advice. (2006广东)

A. I did find

B. did I find

C. I have found

D. have I found

［答案］B

［解析］so difficult放于句首要引起主句的倒装，结果状语从句中的“I decided to ask Tom for advice”表明整句话是针对过去的(不强调与现在的关联)，不宜用现在完成时而应采用一般过去时，因此本题应选B。

［考题2］____ homework did we have to do that we had no time to take a rest. (2006福建)

A. So much

B. Too much

C. Too little

D. So little

［答案］A

［解析］结果状语从句中的“we had no time to take a rest”意味着休息时间很少，应先排除选项C、D，又由于放于句首的表语too much不能引起倒装，而且意思上也难以与全句融合，所以进一步排除B。
