二、
知识讲解与例题精析
分词作状语是高考考查的热点和重要考点,其热点考查内容如下: 一、确定分词形式 分词作状语时,通常放在句首,并且用逗号与主句隔开。同时,分词作状语时其逻辑主语与主句主语应保持一致,也就是说在确定选择现在分词还是过去分词时,要判断主句主语与分词中心词的关系。如果句子的主语是动词-ing形式所表示的动作的发出者(即表主动或正在进行),分词形式选用现在分词;如果句子的主语是动词-ed形式所表示的动作的承受者时(即表被动或完成),分词形式选用过去分词。
例:1, _______, I stretched my hand out for it. A. I saw the book I wanted on the shell B. The book I wanted was on the shell C. Seeing the book lying across the desk D. Lying on the desk

分析:分词作状语时,其逻辑主语应与句子的主语一致。根据这一原则,可知句子的主语I只能与see保持一致。
如果选A, 该句中没有连词,没能构成并列句和主从复合句,此时要选用非谓语动词形式。所以选C 2, Seen from the hill, the park looks very beautiful. 分析:“Seen from the hill”
是过去分词作状语。分词作状语时,其逻辑主语应与句子的主语一致。根据这一原则,可知,“the park”是“Seen from the hill”的逻辑主语,它们之间表示被动关系,所以分词形式用seen.
二.确立句子主语可能是谁 确立句子主语可能是谁时,仍然遵循分词作状语时其逻辑主语与主句主语应保持一致的原则。反过来要根据分词形式确立句子主语。 例:Having been attacked by terrorists, _________. A. doctors came to their rescue
B. the tall building collapsed C. an emergency measure was taken
D. warning were given to tourists 分析: 本题仍考查非谓语动词的用法。句中“Having been attacked by terrorists”是现在分词作状语。分词作状语时,其逻辑主语应与句子的主语一致。根据这一原则,可知“受攻击”的应是“the tall building”, 即“Having been attacked”的逻辑主语是“the tall building”.句意为“大楼因为受到恐怖分子的袭击而倒塌”. 答案: B
三.独立主格结构 分词作状语时其逻辑主语与主句主语应保持一致,但当分词逻辑主语与主语不一致时,分词要有自己独立的逻辑主语,这种主语常常是名词或代词,置于动词-ing形式或动词-ed形式之前。这种名词/代词+动词-ing/动词-ed结构在语法上被称为独立主格结构。此时分词形式的选择取决于名词/代词与v-ing/v-ed形式所表示动作的逻辑关系,如果它们之间表示主动或分词动作正在进行,选择现在分词,如果它们之间表示被动或完成,选择过去分词。
1, 名词/代词+动词-ing 例:Spring coming on, the trees turned green. 2,名词/代词+动词-ed
例:The question settled, they felt released. 3,with/without+名词/代词+动词-ing/-ed 例:With the tree grown tall, we get more shade.

Our school looks beautiful with the flowers coming out. The battle was over without a shot being fired. 四.分词作状语时,相当于一个状语从句。 例:______weight, the doctor has warned me to keep off sugar. A. I’m putting on
B. Having put on
C. As I’m gaining
D. To gain 分析:在并列句和主从复合句中, 逗号只起分隔作用, 前后两部分的逻辑关系必须使用连接词来表达; 否则要使用非谓语动词. 该题中B, C两项是非谓语动词作状语, 但其逻辑主语与主句主语不一致, 所以只能使用连接词来表达前后两部分的逻辑关系. 答案: C
五.现在分词和过去分词作独立成分 英语中一些特殊的分词可用作独立成分,不需要逻辑主语。这种无依着动词形式结构已经成为固定用法。 常见的不需要逻辑主语的动词-ing/-ed形式结构: Considering (that)…考虑到 supposing (that)…
如果…… generally speaking 一般说来 frankly speaking 坦白说 Judging from…
从…判断 talking of… 说到…… Concerning… 关于 setting aside... 除开…… Coming to… 谈到
…… allowing for... 考虑到…… Proving/provided (that)…假定 supposing/suppose (that)…假如…… Seeing (that)…
既然
…… given (that)… 假设;如果;考虑到 put frankly 坦白地说 taken as a whole 总的说来 例:1. Put frankly, I don’t agree with what he said. 坦白地说,我不同意他说的话。 2. Given the general state of his health, it may take him a while to recover from the operation.

考虑到他的一般身体状况,他手术后恢复过来可能需要一段时间。 3. Supposing he is ill, who will do the work? 假如他病了,谁来做这工作呢?
三、课堂运用
一、用作时间状语
1. 典型例句
Seeing the cat, the mouse ran off. 见到猫,老鼠就跑了。
The work finished, he went home. 工作做完后,他就回家了。
2. 理解技巧
分词(短语)用作时间状语通常可转换成时间状语从句(引导时间状语的从属连词需根据句意来确定),如上面两句也可转换成:
When [As soon as] the mouse saw the cat, it ran off.
After the work was finished, he went home.
3. 高考实例
When _______ different cultures, we often pay attention only to the differences without noticing the many similarities. (2006浙江卷) A. compared
B. being compared C. comparing
D. having compared
【分析】此题答案选C,分词短语when comparing different cultures相当于时间状语从句when we compare different cultures。
二、用作原因状语
1. 典型例句
Being very weak, she couldn't move. 她由于身体虚弱而不能行动。
His car broken down, he had to walk. 他的车坏了,所以只好走路。
Much discouraged, she moved on to London. 她很沮丧,搬到了伦敦。
2. 理解技巧
4 / 9
学大教育个性化教案
分词(短语)用作原因状语通常可转换成由as, because, since, now that 等引导的原因状语从句,如上面三句也可转换成:
As she was very weak, she couldn’t move.
Because his car was broken down, he had to walk.
Because she was much discouraged, she moved on to London.
3. 高考实例
(1) ______ with so much trouble, we failed to complete the task on time. (2006四川卷) A. Faced
B. Face
C. Facing
D. To face 【分析】答案选A。现在分词短语faced with so much trouble可转换成原因状语从句because we were faced with so much trouble。
(2) ______ for the breakdown of the school computer network, Alice was in low spirits. (2006福建卷) A. Blaming
B. Blamed
C. To blame
D. To be blamed 【分析】答案选B。现在分词短语blamed for the breakdown of the school computer network可转换成原因状语从句because she was blamed for the breakdown of the school computer network。
三、用作条件状语
1. 典型例句
Working hard, you will succeed. 如果努力工作,你就可以成功。
Adding them all up, we can find the answer. 如果把它们加起来,我们就可以得到答案。
United, we stand; divided, we fall. 团结则存,分裂则亡。
Given more time, we could have done it better. 如果多给点时间,我们可以做得更好。
2. 理解技巧
分词(短语)用作条件状语通常可转换成由从属连词if引导的条件状语从句,如上面几句也可转换成:
If you work hard, you will succeed.
If we add them all up, we can find the answer.
If we are united, we stand; if we are divided, we fall.
If we had been given more time, we could have done it better. 3. 高考实例
______ time,
he’ll make a first-class tennis player. (2003北京春) A. Having given
B. To give
C. Giving
D. Given 【分析】答案选D。give 与其逻辑主语
he 是动宾关系,用过去分词,故选
D。分词短语
Given time 可转
5 / 9
学大教育个性化教案
换成条件状语从顺
If he is given time。
四、用作让步状语
1. 典型例句
Living miles away, he attended the course. 虽然住在几英里以外,他仍去上课。
Defeated, he remained a popular boxer. 虽然被击败了,他仍是一个受欢迎的拳击手。
2. 理解技巧
分词(短语)用作让步状语通常可转换成由从属连词though, although, no matter…等引导的让步状语从句,如上面两句也可转换成:
Although he lived miles away, he attended the course.
Thought he was defeated, he remained a popular boxer.
3. 高考实例
No matter how frequently ______, the works of Beethoven still attract people all over the world. (2006广东卷) A. performed B. performing
C. to be performed D. being performed 【分析】答案选A。现在分词短语performed在此相当于they are performed。No matter how frequently they are performed的意思是“无论它们(指贝多芬的作品)被演奏多少次”。
五、用作伴随状语
1. 典型例句
He sat in the chair reading a newspaper. 他坐在椅子上看报。
Don't you sit there doing nothing. 别什么也不干坐在那里。
He came in, followed by his wife. 他走了进来,后面跟着他的妻子。
2. 理解技巧
理解“伴随状语”的关键是要理解“伴随”二字。分词(短语)用作伴随状语时,它表示的动作伴随句子谓语动作同时发生,即句子谓语所表示的动作为主要动作,分词短语所表示的动作伴随性的次要动作。
3. 高考实例
(1) Don’t sit there ______ nothing. Come and help me with this table. (2006湖北卷) A. do B. to do C. doing D. and doing (2) My cousin came to see me from the country, ______
me a full basket of fresh fruits. (2006安徽卷) A. brought B. bringing C. to bring D. had brought

(2006全国卷) A. thinking B. think C. to think D. thought 【分析】以上四题答案分别为CBAA。
六、用作方式状语
1. 典型例句
He earns a living driving a truck. 他靠开卡车谋取生。
I'm returning you letter as requested. 我按要求给你退信。
2. 理解技巧
分词(短语)用作方式状语与用作伴随状语的情形比较接近。有时用作方式状语的现在分词可以转换成by doing sth的结构,如上面第一句也可换成:
He earns a living by driving a truck.
注:近几年高考对分词用作方式状语的情形考得较少。
七、用作结果状语
1. 典型例句
He fired, killing one of the passers-by. 他开枪了,打死了一个过路人。
He died, leaving his wife with five children. 他死了,留下他妻子和五个儿子。
It rained and rained, vehicles bogged and bridges washed out. 雨不停地下,车辆陷入泥沼,桥梁被水冲去。
