十、狀語(yǔ)從句的省略

狀語(yǔ)從句同時(shí)具備下列兩個(gè)條件:①主句和從句的主語(yǔ)一致，或從句主語(yǔ)為it；②從句主要?jiǎng)釉~是be的某種形式。從句中的主語(yǔ)和be動(dòng)詞�？墒÷�。例如：

When ( the museum is ) completed , the museum will be open to the public next year .

I’m taller than he (is tall ).
　　我比他高

The higher the temperature (is), the greater the Pssure (is ).
　　溫度越高，氣壓越大

就狀語(yǔ)從句而言,有時(shí)為了使語(yǔ)言言簡(jiǎn)意賅,常常將狀語(yǔ)從句進(jìn)行"簡(jiǎn)化"。狀語(yǔ)從句的"簡(jiǎn)化"現(xiàn)象在口語(yǔ)中較為普遍,而且在高考中的復(fù)現(xiàn)率也較高。因此,有必要對(duì)其進(jìn)行全面、透徹的了解。

狀語(yǔ)從句的"簡(jiǎn)化"現(xiàn)象常存在于以下五種狀語(yǔ)從句中:①由if, unless等引導(dǎo)的條件狀語(yǔ)從句;②由although, though, even if / though等引導(dǎo)的讓步狀語(yǔ)從句;③由when, while, as, before, after, until / till等引導(dǎo)的時(shí)間狀語(yǔ)從句;④由as, as if等引導(dǎo)的方式狀語(yǔ)從句;⑤由as, than等引導(dǎo)的比較狀語(yǔ)從句。下面針對(duì)這五種情形作一歸納。

(1)當(dāng)狀語(yǔ)從句的主語(yǔ)是it,且謂語(yǔ)動(dòng)詞是be時(shí),it和be要完全簡(jiǎn)化掉。例如:

If (it is) possible, he will help you out of the difficulty.
　　如果可能的話,他會(huì)幫你擺脫困境。

You must attend the meeting unless (it is) inconvenient to you。
　　除非情況對(duì)你來(lái)說(shuō)不方便,否則你必須出席這次會(huì)議。

(2)當(dāng)狀語(yǔ)從句的主語(yǔ)和主句的主語(yǔ)一致時(shí),從句可以將主語(yǔ)和be動(dòng)詞簡(jiǎn)化掉。常用于以下幾種情形:

連詞+形容詞

As (he was) young, he learned how to ride a bike.
　　他小時(shí)候就學(xué)會(huì)了騎自行車(chē)。
