在中学教材中，经常遇到省略某种或某些成分的状语从句，一般说来，状语从旬的省略有以下几种情况：
一、如果状语从句中的主语和主句中的主语一致。在状语从句中常可省略主语或主语加系动词。具体省略结构如下；
1. when, while, as, if, unless, until, once, evenif/though, than等+分词。例如：
When crossing (=When you are crossing) thestreet, you should be careful.
While studying (ffiWhile I was studying) atcollege, I knew a lot of foreign frlends.
If heated (ffiIf water is heated), water can bechanged into vapor.
Unless invited (=Uuless I am invited), I won’tgo to the evening party.
Even if/though invited (Even if/though I aminvited), I won’t go to his birthday party.
Once seen (=Once the film is seen), the filmwill never be forgotten.
Our Chinese team has won the match asexpected (as they are expected).
2. while, as if/though等+介词短语。例如：
While in America (=While I was in America),I learned a lot about American customs.
He looked everywhere as if in search ofsomething (=as if he was in search of something).
3. as, as if/though等+名词。例如：
As a young man (=As he was a young man),Lincoln worked as a storekeeper.
My stepfather treated me as if my own father(=as if he was my own father).
4. whether, though, when等+形容词。例如：
Whether young or old (=Whether they areyoung or old), they all like sports and games.
Though young (=Though he is young), heknows a lot about Chinese history. 二、如果状语从句中的主语是it，谓语是be的各种形式，或状语从句是there be句型时，常可把it和be或there be省略。具体省略结构如下：
1if, unless, when, whenever +形容词。例如：
Some saldiers would ask him about the threequestions whenever possible (=whenever it waspossible).
You’r better not look up new words in thedictionary when you reading unless necessary(=untess it is necessary).
2. if+any.例如：
Correct the mistakes in the follwing sentencesif any (=if there is any). 三、如果as’thin引导比较状语从句，在前后句意非常明确的情况下，常可省略as和than从句中各种成分。例如：
I know English better than French (=than Iknow French). (省略谓语和宾语)
Mary is wearing the same coat as Jane (=asJane were the coat). (省略谓语和宾语)
In winter it’s colder in Jilin province than inShandong Province (=than it’s in Shandongprovince). (省略主语和系动词)
