Ⅰ、狀語從句中的省略用法
一、如果從句的主語和主句的主語一致，且從句的謂語含有be動詞的某種形式(am/is/are/was/were)，可同時省略從句的主語和be動詞的某種形式。
1、when，while引導(dǎo)的時間狀語從句
e.g. Do be careful when (you are) crossing the street.
When/While (I was) on my way to work, I met her.
2、if，unless，once引導(dǎo)的條件狀語從句
e.g. If (it is) properly treated, waste will do no harm to the environment.
I’ll not go to the party unless (I am) invited.
Once (you are) caught stealing in a supermarket, you will be punished.
3、though，although，whether，no matter whether/what/how/who等引導(dǎo)的讓步狀語從句
e.g. He was happy, though/although (he was) poor.
Whether (she is) sick or well, she is always cheerful.
No matter how/However hard the task (is), we must fulfill it in time.(注：從句的主語和主句的主語不一致時，只省略從句中的be動詞形式)
4、as if，as though引導(dǎo)的方式狀語從句
e.g. He rubbed his eyes and yawned as if/though (he was) waking up after a long sleep.
He stood up as if/though (he wanted) to leave.(as if/though + to do表示一個將來的動作)
二、than，as引導(dǎo)的比較狀語從句中的省略用法：
當(dāng)不同的主語進行比較時，一般省略從句中的謂語;當(dāng)從句中的主語與謂語(be動詞除外)和主句中的`主語與謂語相同時，通常省略從句中的主語和謂語，只保留比較部分。
e.g. He is taller than his brother (is).
I have as much as confidence in you as (I have confidence) in him.
三、以if從句為代表的狀語從句中的特殊省略用法：通常省略了it is，that is，there is/are。
e.g. If (it is) possible/necessary, this old temple will be rebuilt.
If (that is) so, I will call you back at 5:00 pm.
There are only a few books in our school library, if (there are) any.
Ⅱ、定語從句中的省略用法
關(guān)系詞的省略 關(guān)系代詞that，which，whom等在限制性定語從句中充當(dāng)賓語且不位于介詞之后時，可以省略;in which或that在先行詞way后作方式狀語從句時可省略。
e.g. The man (that/who/whom) you visited last night is my grandpa.
I don’t like the way (in which/that) you treat the girl.
Ⅲ、虛擬語氣中if及should的省略
1、當(dāng)條件狀語從句中有were，had，should等時省略if，把它們提至句首，形成倒裝句。
e.g. If I were a teacher, I would be strict with my students.
= Were I a teacher, I would be strict with my students.
2、Suggest，insist，order，require等表示建議、要求、命令的動詞后接的名詞性從句中，謂語動詞常用“should+動詞原形”，should可以省略。
e.g. The doctor suggested that he (should) try to lose weight.
�、�、不定式符號to的省略
1、感官動詞see，hear，feel，watch等和使役動詞have，make，let等后接不定式作賓語時，不定式省略to。
2、do nothing but，can’t help but等結(jié)構(gòu)常接省略to的不定式。
e.g. We didn’t do anything but stay at home watching TV yesterday.
Hearing the news, she couldn’t help but cry.
3、在特定語境中為了避免重復(fù)，當(dāng)不定式再次出現(xiàn)時，在want，wish，hope，try，plan，like，love，hate后往往只保留to，而省略后面的動詞。但不定式后有be，have時，也保留be和have。
e.g. My parents encouraged me to go to college, but I didn’t want to.
Ⅴ、So和not的替代性省略
用于避免重復(fù)前面所說過的內(nèi)容，替代詞so/not替代肯定或否定的名詞性從句�？膳cbelieve，do，expect，fear，guess，hope，say，speak，suppose，think，I’m afraid等連用
e.g. – Do you suppose he is going to attend the meeting
