一、分词的分类及形式
1. 现在分词的形式:
现在
及 物 动 词 write
不及物动词go
分词
主动语态
被动语态
主动语态
一般式
writing
being written
going
完成式
having written
having been written
having gone
否定式:not + 现在分词
1)现在分词的主动语态:现在分词主动语态的一般式表示与谓语动词所表示的动作同时发生,完成式表示的动作在谓语动词所表示的动作之前发生,常作状语。例如:
They went to the park, singing and talking.
Having done his homework, he played basket-ball.
2)现在分词的被动语态:一般式表示与谓语动词同时发生的被动的动作,完成式表示发生在谓语动词之前的被动的动作。
The problem being discussed is very important.
Having been told many times, the naughty boy made the same mistake.
2、过去分词的形式:(done)
过去分词只有一般式,没有完成式,也没有主动语态。
总结:现在分词和过去分词作定语时的区别是:
A.从语态角度来讲,现在分词表示主动意义。而过去分词通常表示被动意义(不及物动词的过去分词除外)。
B.从时态角度来讲,现在分词一般表示进行的动作,过去分词表示完成的动作。
二、分词的用法
1. 分词作定语
1)分词作定语既可以放在所修饰的词之前,作前置定语,也可以放在所修饰的词后面,作后置定语。其作用相当于一个定语从句。例如:
Where are the reserved seats? (=Where are the seats which have been reserved?)
预定的座位在哪里?
This is a pressing problem. (=This is a problem which is pressing.)
这是一个紧迫的问题。
2)分词作后置定语可分为限制性(紧跟在所修饰的中心词之后)和非限制性(用逗号与其所修饰的中心词分开)两种,其作用分别相当于一个限制性定语从句和非限制性定语从句。例如:
The funds raised (= which have been raised) are mainly used for helping the homeless.
筹集的资金主要用来帮助那些无家可归的人。
There are many students waiting (= who are waiting) to get examined.
有许多学生在等待检查。
This book, written (= which is written) in simple English, is suitable for beginners.
本书是用浅显的英语写的,适合初学者。
3)分词常和形容词、副词或名词构成合成形容词作定语。例如:
The flower-carrying girl must be waiting for someone.
那位手持鲜花的姑娘一定在等人。
The newly-built building is our office building.
这座新建的大楼是我们的办公楼。
4)有些不及物动词的过去分词作定语,并不表示被动的意思而是表示完成。这类过去分词常作前置修饰语。例如:
There are a lot of fallen leaves in autumn.
秋天有许多落叶。
The film describes the story about the police who pursue an escaped man.
这部电影描述的是警察抓逃犯的事。
常用的这一类词有:fallen, faded, returned, retired, risen, grown up, vanished等。
2. 分词作宾语补足语
1) 跟分词作宾补的动词有:catch, have get, keep, hear, find, feel, leave, make, want, start, notice, observe, watch, set等。例如:
When they returned home from the holiday, they found their house stolen.
当他们度假完回到家时,发现房子被盗了。(过去分词表示被动)
We want this work finished quickly.
我们要求这项工作很快完成。
2)在复合宾语中,用现在分词作宾补,说明宾语是动作的发出者,形成逻辑上的主谓关系;用过去分词作宾补,表示宾语是动作的承受者,构成逻辑上的动宾关系。例如:
There was so much noise that the speaker couldn't make himself heard.
由于十分吵闹,讲话人没法让人听到他的声音。
When he awoke, he found himself being looked after by an old woman.
他醒来的时候发现一位老大娘正在照顾他。
3. 分词作状语
1)分词或分词短语作状语时,可以表示时间、原因、让步、条件、方式或伴随状况。通常可转换成相应的状语从句;表示方式或伴随状况的可以转换成并列句或非限制性定语从句。例如:
Confined to bed (= Because she was confined to bed), she needed to be waited on in everything.
她卧病在床,什么事都需要人伺候。(作原因状语)
Having only book knowledge (= If you only have book knowledge), you will not be able to work well.
如果只有书本知识,你就不可能做好工作。(作条件状语)
They stood there waiting for the bus. (=They stood there and waited for the bus.)
他们站在那里等公共汽车。(作方式状语)
(1)、表示时间,分词短语一般至于句首。
多数情形下,分词动作发生于谓语动作之前,有时候分词动作和谓语动作同时发生。
e.g. Having watered the garden, he began to mow the lawn.(分词动作发生于谓语动作之前)
Riding in the street during the rush hours, you must be careful.(分词动作和谓语动作同时发生)
(2)、表示原因,分词短语可置于句首或句末,有时还可以置于主谓之间。
e.g. Not knowing what to do next, I want to ask for your advice.
(3)、表示条件,通常放在句首
e.g. Given more time, I would be able to complete it.
(4)、表示让步,通常放在句首
e.g. Having lived in Canada for three years, he still can`t speak English well.
(5)、表结果,一般只放在句末。
e.g. I went home, finding the door locked
(6)、表伴随状况,补充说明或方式,分词短语置于句首或句末均可。
e.g. He came running breathless and told me the results.
2) 现在分词和过去分词作状语时的用法比较
不管是现在分词还是过去分词作状语,如果单独作状语,其逻辑主语必须和主句的主语一致。分词作状语通常可以转换成一个相应的状语从句,如果状语从句中的谓语动词为被动结构,就用过去分词;如果状语从句中的谓语动词为主动结构,就用现在分词。有时为了强调,分词前可带连词when, while, if, though, as if, unless等一起作状语,以便使句子的意思更清楚、更连贯。例如:
Working hard (If you work hard), you will succeed.
如果你努力,你会成功的。
Defeated (= Though he was defeated), he remained a popular boxer.
虽然他被击败了,但他仍然是一个受人喜爱的拳击手。
4. 分词的独立结构
1)分词作状语时,要特别注意其逻辑主语必须和谓语动词的主语一致。否则,分词必须有自己的主语,这种带主语的分词被称为分词的独立结构,或叫独立主格。在句中作状语,表示时间、原因、条件等。例如:
The project finished, they had a two weeks' leave.
完成那个计划后,他们休了两周假。
He being absent, nothing could be done.
由于他缺席,什么事也没法干。
2) 独立结构有时也可以用“with/ without + 名词(或代词的宾语)+ 分词”的结构,表示伴随状况。例如:
They sat there silently,(with) their eyes fixedon the lake.
他们静静地坐在那里,眼睛看着湖面。
With him helping me, I felt lucky.
有他的帮助,我感到很幸运。

Ⅰ.阅读理解
Several companies in Europe, the U.S. and Asia have decided to change one of the processes of making chocolate and no longer roast the cacao beans. They insist that growers in Africa and South America leave them outdoors to dry naturally instead. The resulting product is called “raw” chocolate.
Producers claim that avoiding exposure to oven temperatures allows the preservation of nutrients such as iron, zinc, copper and vitamin C. It’s also claimed that uncooked cacao contains higher levels of antioxidants(抗氧化物)than roasted cacao used in most chocolate.
“Over the last 10 years, consumers have become more involved in their food and drink, ”says Kris McGowan, who runs the Raw Chocolate Company. “They care a lot more about its healthy qualities and chocolate is no exception.”
But Martin Schweizer, professor of biochemistry at HeriotWatt University, urges caution on describing raw chocolate as a super food until more research is carried out. “We have to look at this in more depth. The research is at a fairly early stage.”
There are concerns that not heating them to about 150℃ could mean an increase in bacteria. However, producers insist that, as no animal products are involved,
there is no greater risk than when dealing with vegetables such as carrots or lettuces.
Jennifer Earle, a writer on chocolate, is unconvinced by it on taste grounds. “It’ s the quality of the cacao that makes a difference, not whether the chocolate is‘raw’or not, ”she says.“And if you’re talking about health, I’d rather eat some topquality ordinary chocolate and have a plate of vegetables afterwards. ”
1.Chocolate bean growers in Africa ________.
A.dry the beans outdoors naturally
B.roast the beans at a low temperature
C.cook the beans in pots instead of in ovens
D.store the beans with uncooked vegetables
2.Producers of raw chocolate claim that ________.
A.it can fight bacteria
B.it is very ecofriendly
C.it preserves more nutrients
D.it contains less antioxidants
3.Jennifer Earle, a writer on chocolate, thinks that ________.
A.roasted cacao is cleaner
B.raw chocolate is healthier
C.raw chocolate tastes better
D.cacao quality matters more
4.We can infer from the text that________.
A.not much research has been done on raw chocolate
B.raw chocolate has become the most popular variety
C.children face the risks from bacteria when eating raw chocolate
D.all consumers have turned to raw chocolate for health concerns
II.语法填空

1.The hospital has recently obtained new medical equipment, ________ more patients to be treated.
A. being allowed B. allowing C. having allowed D. allowed
【答案】B
【解析】考查非谓语。句意:这个医院近期购进了新的医疗设备,允许更多的病人被治疗。前句购进医疗设备和后面允许更多的病人被治疗之间是必然的结果关系,用doing作结果状语,表示顺理成章的结果。故选B。
2. carefully for long time, the opening ceremony won a great success.
A. Having prepared
B. To be prepared
C. Being prepared
D. Having been prepared
【答案】D
【解析】考查非谓语性动词作状语。prepare的逻辑主语是the opening ceremony,且和逻辑主语是被动关系,再加上prepare动作明显发生在谓语之前,所以用现在分词完成时的被动形式作状语。句意:通过长时间精心的准备,这个开业典礼取得了巨大的成功。故选D。
3.Many Chinese brands, ________their reputations over centuries, are facing new challenges from the modern market.
A. having developed B. being developed C. developed D. developing
【答案】A
【解析】考查非谓语。分析句子,后面的are facing是谓语动词,所以此空应该填非谓语动词。brands是逻辑主语,和develop是主谓关系,所以用现在分词,表伴随状况;再根据“over centuries”可知,应该使用现在分词的完成式,故选A。句意:许多中国品牌经过几个世纪的发展,现在正面临着来自现代市场的新挑战。
4. which university to attend, the girl asked her teacher for advice.
A. Not knowing
B. Knowing not
C. Not known
D. Known not
【答案】A
【解析】句意:不知道上哪个大学,女孩向老师征求意见。The girl和know是主动关系,用现在分词作状语,根据句意看是否定含义,否定词not放在knowing前面,选A。
5.Newly-built wooden cottages line the street, ________ the old town into a dreamland.
A. turn B. turning C. to turn D. turned
【答案】B
【解析】考查非谓语。句意:新建的木屋林立在街道的两旁,使古镇变成了一个梦幻之地。turn的逻辑主语是cottages,两者是主动关系,故用v-ing形式,表示主动和伴随,故选B。
6.In art criticism, you must assume the artist has a secret message ________ within the work.
A. to hide B. hidden C. hiding D. being hidden
【答案】B
【解析】考查非谓语。句意:在艺术批评中,你必须假定艺术家在作品中隐藏着一条秘密信息。本句中的名词短语a secret message与动词hide构成被动关系,故使用过去分词短语hidden within the work在句中作后置定语,修饰名词短语a secret message,相当于定语从句that is hidden within the work。A和C项表示主动含义,D项强调正在进行,与语境不符。
8. Many people of non-Chinese background are enrolled in universities on courses _________ (design) for foreigners to learn Chinese.
【答案】designed
10. The park was full of people, ________ themselves in the sunshine.
A. having enjoyed B. enjoyed C. enjoying D. to enjoy
【答案】C
【解析】考查非谓语。句意:这个公园充满了人,在阳光下他们玩得很尽兴。本空所在句子与前一句用逗号隔开,没有连词,故判断此处用非谓语形式;逻辑主语为people,人们玩得开心是主动的,因此排除B选项;D项不定式表示动作未发生,由题干可知,是过去的动作,因此排除D选项;A项having enjoyed为现在分词的完成形式,一定要发生在谓语动作之前,根据题意,不符合。故选C。
11. ________ for two days, Steve managed to finish his report on schedule.
A. To work B. Worked C. To be working D. Having worked
【答案】D
【解析】考查非谓语。句意:工作了两天,Steve设法按时完成了他的报告。分析句子,后一句有谓语动词managed,所以此空用非谓语形式;句中的逻辑主语为Steve,与work之间为主动关系,故用v-ing形式,这里用having worked表示动作先于谓语动词之前发生,故选D。
10.________ the difference between the two research findings will be one of the worst mistakes you make.
A. Ignore B. Ignoring C. Ignored D. Having ignored
【答案】B
【解析】考查非谓语。句意:忽视这两项研究结果的差异将会是你所犯下的最为严重的错误之一。句子缺少主语,ignore的逻辑主语是you,两者是主谓关系,因此用动名词作主语。
11.___________________ some officials, Napoleon inspected his army.
A. Followed B. Followed by C. Being followed D. Having been followed
【答案】B.
【解析】Napoleon 与follow 之间有被动的含义。being followed除表达被动之外,还有动作正在进行之意。 followed by(被…跟随)。本题可改为: With some officials following, Napoleon inspected his army.
12. There was a terrible noise _______________ the sudden burst of light.
A. followed B. following C. to be followed D. being followed
【答案】B.
【解析】由于声音在闪电后,因此为声跟随着光,声音为跟随的发出者,为主动。用现在分词。
13. ______________________, liquids can be changed into gases.
A. Heating B. To be heated C. Heated D. Heat
【答案】C.
【解析】本题要选分词作为状语。现在分词表主动,正在进行的;过去分词表被动的,已经完成的。对于液体来说是加热的受动者,是被动的,因而选C。它相当于一个状语从句 When it is heated,…
注意:选择现在分词还是过去分词,关键看主句的主语。如分词的动作是主句的主语发出,分词就选用现在分词,反之就用过去分词。例如:
Used for a long time, the book looks old. 由于用了很长时间,这本书看上去很旧。
Using the book, I find it useful. 在使用的过程中,我发现这本书很有用。
