14、现在分词作状语时,现在分词所表示的动作与句子主语之间构成逻辑上的主动关系。之间构成逻辑上的主动关系。He went out,shutting the door behind him.他出去后将他出去后将门随手关上。门随手关上。Not knowing what to do,he went to his parents for help.由于不知如何办是好,他去找父母帮忙。由于不知如何办是好,他去找父母帮忙。2)过去分词作状语时,过去分词所表示的动作与句子主语过去分词作状语时,过去分词所表示的动作与句子主语之间构成逻辑上的被动关系。之间构成逻辑上的被动关系。Given more encourage

15、ment,the boy could have behaved better.如果多给这个孩子一些鼓励,他本来会表现得更好。Faced with difficulties,we must try to overcome them.在遇到困难时,我们必须设法克服。3)部分过去分词来源于系表结构,作状语时不表示部分过去分词来源于系表结构,作状语时不表示“被动被动关系关系”,其前不用,其前不用being。这样的过去分词及短语常见的有:。这样的过去分词及短语常见的有:lost in(陷入某种状态)、(陷入某种状态)、seated(坐着的)、(坐着的)、hidden(躲着)、(躲着)、stationed

16、(驻扎)、(驻扎)、lost/absorbed in(沉溺(沉溺于)、于)、born in(出身于)、(出身于)、dressed in(穿着)、(穿着)、tired of(厌烦了)等。(厌烦了)等。Lost/absorbed in deep thought,he didnt hear the sound.因为沉溺于思考中,所以他没有听到那个声音。Born in this beautiful town,he hates to leave it.出生于这个美丽的小镇,他不愿离开它。2时间概念过去分词所表示的动作发生在谓语动作之前,或表示“一种状态”,与谓语动作同时发生或存在。现在分词的一般式(do

17、ing)表示的动作与谓语动作同时发生或在说话时正在进行;现在分词的完成式(having done)表示发生在谓语动作之前的一个“主动”动作;现在分词的完成式的被动式(having been done)常和表示次数的短语及时间段(for+一段时间)连用,表示发生在谓语动作之前的一个“被动动作”,这种情况下不能用过去分词替换,其它情况下通常被过去分词所替换,使句式更简洁。Written in a hurry,this article was not so good.因为写得匆忙,这篇文章不是很好。Reading carefully,he found something he hadnt known

18、 before.他仔细读书时,发现了一些从前不知道的东西。Having finished his homework,he went home.完成了作业,他就回家了。Having been discussed several times,the decision was finally made.进行了几次讨论后,终于做出了决定。小练习:用所给动词的正确形式填空 1._(dress)in a white uniform,he looks more like a cook than a doctor.2._(put)into use in April 2000,the hotline was m

23、ice 答案:1.A2.A3.B4.A5.A6.A7.C二、垂悬分词结构 若分词的逻辑主语必须同句子的主语不一致,在传统语法把它叫做“垂悬分词”,认为不合语法,但在今天的科技英语里“垂悬分词”确是一种常见结构。由于垂悬结构具有两重性特征,在语言实践中,我们对垂悬结构的使用宜取宽容、慎重的公正态度:既承认它的可用性,不一概摒弃;亦不否认它的非可用性,避免盲目滥用。When installing a boiler,the floor space which is available is very important.安装锅炉时,地面可供利用的空间是很重要的。(被认可并接受)Please take

24、 out the battery and keep it in a dry place if not used for more than two months.(被认可并接受)Standing on top of the tall building,the whole city could be seen.(不被认可)其实上述句子是错误的。正确的应该是:Standing on top of the tall building,we could see the whole city.或者:when we stood on top of the tall building,we could se

25、e the whole city.下面是垂悬结构的改正方法:Climbing up the hill,several boars were seen.(X)(a)确定是逻辑主语,使句子变成:Climbing up the hill,the explorers saw several boars.We climbing up the hill,several boars were seen.(b)把现在分词短语扩大为副词分句(也称状语从句):When the explorers climbed up the hill,they saw several boars.When the explore

26、rs climbed up the hill,they several boars were seen.三、独立主格结构或用独立主格结构或用with复合结构复合结构 如果分词作状语的逻辑主语不是句子的主语,如果分词作状语的逻辑主语不是句子的主语,须在分词前面加上它自己的主语,但这种结须在分词前面加上它自己的主语,但这种结构叫独立主格结构,其作用相当于状语从句;构叫独立主格结构,其作用相当于状语从句;或用或用with复合结构(复合结构(with+宾语宾语+宾补)作状宾补)作状语。语。如:如:After her tea was finished,she went on with her work.

27、=Her tea finished,she went on with her work.喝完茶后,她继续工作。喝完茶后,她继续工作。This done,we went home.做完此事,做完此事,我们就回家了。She gazed,her hands clasped to her breast.她凝视着,双手叉在胸前。All our savings gone,we started looking for jobs.积蓄全部花完了,我们就开始找工作。With the fire burning all the night,she had a sound sleep.尽管大火烧了一夜,她还是睡的很香

28、。独立主格结构主要用于描绘性文字中,其作用相当于一个状语从句,常用来表示时间、原因、条件、行为方式或伴随情况等。例如:1)表示时间 The meeting being over,all of us went home.开完会后我们都回家了。开完会后我们都回家了。=When the meeting was over,all of us went home.Her work done,she sat down for a cup of tea.她干完了活,坐下来喝茶。她干完了活,坐下来喝茶。=After her work was done,she sat down for a cup of tea

30、 and frosty.夜又黑又冷,所以他夜又黑又冷,所以他把她裹得严严实实的。把她裹得严严实实的。=He wrapped her up with great care,since the night was dark and frosty.4)表示伴随情况 Almost all metals are good conductors,silver being the best of all.几乎所有的金属都是良导体,而银则是最好的导体。(=Almost all metals are good conductors,and silver is the best of all.)独立主格结构的形式

31、主要有:独立主格结构的形式主要有:1)名词名词/主格代词主格代词+现在分词现在分词 名词名词/主格代词与主格代词与现在分词现在分词之间是主谓关系。之间是主谓关系。如:The girl staring at him(=As the girl stared at him),he didnt know what to say.姑娘两眼望着他,他不知道说什么好。Time permitting(=If time permits),we will go for an outing tomorrow.如果时间允许的话,我们明天去郊游。2)名词)名词/主格代词主格代词+过去分词过去分词名词名词/主格代词与过去
