一般说来省略现象多出现在下列五种状语从句中：由 when ,while ,as ,before, after , till, until, once等引导的时间状语从句；由whether ,if , unless 等引导的条件状语从句；由 though , although ,even if ,whatever等引导的让步状语从句；由 as ,than 等引导的比较状语从句；由as, as if , as though 等引导的方式状语从句。上述状语从句在省略时，并非任何成分都可以省略而是遵循下面原则：
① 连词（as, as if , once）+ 名词
如：Once (he was)a worker ,Pang Long now becomes a famous singer .庞龙曾经是个工人，现在变成一位著名的歌手。
②连词（ though, whether , when）+形容词
如：Work hard when (you are) young ,or you'll regret.趁年轻要努力学习，要不然你会后悔的。
③连词(whether, as if ,while )+介词短语
如：He looked everywhere as if (he was)in search of something .他到处看似乎在找什么东西。
④连词(when , while , though )+ 现在分词
如：While (he was) holding talks with President Hu Jintao , US President George W. Bush thanked China for its important role in the Six-Party Talks.美国总统布什在与主席会谈时，感谢中国在六方会谈中起的重要作用。
⑤ 连词(when ,if ,even if ,unless ,once ,until, than , as ) + 过去分词
如：The exhibition is more interesting than (it was) expected .这次展览比被预料的有趣的多
⑥ 连词(as if ,as though ) + 不定式
如：Olympic gold medallist hurdler Liu Xiang opened his lips as if (he were) to speak .奥林匹克金牌获得者跨栏运动员刘翔张开嘴好象要说什么。
（2）当从句的主语与主句的主语不一致，但从句主语是 it，从句中又含有系动词be 的某种形式时 ，可以把it和系动词be一起省略。。如：Unless (it is) necessary ,you'd better not refer to the dictionary.如果没有必要，你最好不要查字典。

注：as在引导时间状语从句时，没有这种省略现象。我们不可说As walking, she found a nice shining thing on the ground.
地点状语从句的省略常用下列结构：where(ver) possible, where(ver) necessary,
Lay these books where possible you can find them easily. 把这些书放在你可能容易找到的地方。
Put in articles wherever necessary in the following passages. 在下列文章中需要的地方填入冠词。
常用的句型是：if necessary, if possible, if true, if anyone等。如：

He will come if (he is) asked. 如果叫他来，他就来。
If (it is) necessary, ring me at home. 如果有可能，朝我家里打电话。

4. with或without-名词/代词 +动词不定式；
5. with或without-名词/代词 +分词。

2、 With the meal over , we all went home.(with+名词+副词,作时间状语)

4、He lay in the dark empty house,with not a man ,woman or child to say he was kind to me.(with+名词+不定式,作伴随状语) He could not finish it without me to help him.(without+代词 +不定式,作条件状语)
5、She fell asleep with the light burning.(with+名词+现在分词 ,作伴随状语) Without anything left in the cupboard, shewent out to get something to eat.(without+代词+过去分词,作为原因状语)

2.From space the earth looks like a huge water-covered globe with a few patches of land sticking out above the water.
3.A little boy with two of his front teeth missing ran into the house.
1. with结构由介词with或without+复合结构构成。复合结构中第一部分与第二部分语法上是宾语和宾语补足语关系,而在逻辑上,却具有主谓关系,也就是说,可以用第一部分作主语,第二部分作谓语,构成一个句子。例如： With him taken care of,we felt quite relieved.(欣慰)→(He was taken good care of.) She fell asleep with the light burning. →(The light was burning.) With her hair gone,there could be no use for them. →(Her hair was gone.)
2. 在with结构中,第一部分为人称代词时,则该用宾格代词。例如： He could not finish it without me to help him.
1. with结构在句子中的位置： with 结构在句中作状语,表示时间、条件、原因时一般放在句子前面,并用逗号与句子分开；表示方式和伴随状况时一般放在句子后面,不用逗号分开。若with结构作定语,则放在所修饰的名词之后,一般不用逗号隔开。
2. with结构作状语时,不定式、现在分词 、和过去分词的区别： 在with结构中,不定式、现在分词作宾补,表示主动,但是不定式表示将要发生的动作,而现在分词表示正在发生或发生了的动作；过去分词表示被动或完成。
例如： With the boy leading the way,we found he house easily.(小男孩已领过路)
With the boy to lead the way,we will find the house easily tomorrow.(小男孩明天将领路)
He lay on the bed with the bedroom door shut.(寝室被关着)
3. with结构与一般的with短语的区别： with结构具有上述功能和特点,而"介词with+名词或代词(组)"组成的一般的with短语在句子中可以作定语和状语。作状语时,它能表示动作的方式、原因,但不能表示时间、伴随和条件。在一般的with短语中,with后面所跟的不是复合结构,也根本没有逻辑上的主谓关系。
4. with结构与独立主格结构的关系： with结构属于独立主格结构,但在结构上,with结构由介词with或without引导,名词前有冠词、形容词、所有格代词或其它词类所修饰,结构较松散；而独立主格结构没有with或without引导,结构严密,名词前可用可不用修饰语。在句法功能上,with结构可以作定语,独立主格结构则不能；独立主格结构通常在句中作状语,但也可以作主语,而with结构则不能。
There were rows of white houses with trees in front of them.("with+复合宾语"结构,在句中作定语)
A strong man working a whole day could not jump this high.(名词+现在分词构成的独立主格结构,作主语)
The boy said,turning to the man,his eyes opened wide and his hand raised.(独立主格结构,表示伴随状况或行为方式,作状语)
Then last night,I followed him here,and climbed in,sword in hand.(名词+介词短语构成的独立主格结构,作状语,表示伴随情况) board, she went out to get something to eat.(without+代词+过去分词,作为原因状语)
