1、when，while引導的時間狀語從句
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引導的條件狀語從句e.g. If (it is) properly treated, waste will do no harm to the environment.

3、though，although，whether，no matter whether/what/how/who等引導的讓步狀語從句
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引導的比較狀語從句中的省略用法：
當不同的主語進行比較時，一般省略從句中的謂語；當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.
�、�、定語從句中的省略用法
關系詞的省略 關系代詞that，which，whom等在限制性定語從句中充當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.

1、當條件狀語從句中有were，had，should等時省略if，把它們提至句首，形成倒裝句。

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.
�、簟⒉欢ㄊ椒杢o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等結構常接省略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，當不定式再次出現時，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.

e.g. – Do you suppose he is going to attend the meeting? – I suppose not
Ⅵ、日常交際中的省略
在情景會話中，答語常常省略不會引起歧義的主語、謂語或賓語部分，而只保留對方希望了解的內容。在復合句或并列句中，也有省略主、謂、賓的情況。
e.g. – How many copies do you want? -- (I want) Three copies, please.
-- Have you ever been to the Great Wall? -- No, (I have) never (been to the Great Wall).
