狀語從句可能涉及的三類省略

一、省略主語和動(dòng)詞be

當(dāng)狀語從句的主語與主句主語一致，且從句謂語包括有動(dòng)詞be時(shí)，有時(shí)可省略從句中的主語和動(dòng)詞be。如：

Phone me if (it is) necessary. 必要時(shí)給我打電話。

Start when (you are) ready. 準(zhǔn)備好了就開始。

He danced about as if (he was) in search of something. 他向四周望望，仿佛在找什么似的。

Though (he was) intelligent, he was very poorly educated. 雖然他很聰明，受的教育卻很差。

注：有時(shí)省略的可能是 there is, it is 等。如：

There is few if (there is) any. 如果有也很少。

Fill in the application as (it is) instructed. 按照要求填好表格。

As (it is) scheduled they met on January 20. 他們按照計(jì)劃在1月20日碰頭。

二、結(jié)果狀語從句省略that

so that, so…that, such…that 引導(dǎo)結(jié)果狀語從句時(shí)，有時(shí)可省略that。如：

She spoke with such sincerity (that) he felt greatly touched. 她說得那樣誠懇，他深受感動(dòng)。

三、比較狀語從句的省略

as, than等引出的比較大狀語從句通常省略謂語。如：

I know you better than he (does). 我比他更了解你。
