[我的发现] (1)以上各句中的黑体部分在句中担当的成分不尽相同。黑体部
分在第⑥、⑦、⑧句中作 定 语;在第④句中作表语;在第 ②句中作补语 ;在第①、③、⑤、⑨句中作 状语。 (2)从以上第⑥、⑦、⑧句来看,现在分词在句中作定语时位置 不同。单个的分词作定语时,一般放在所修饰名词的前面; 分__词__短__语__作定语时通常放在所修饰名词的后面。

(3)第①、③、⑤句中现在分词表示的动作与谓语动词 表示的 动作发生的时间不同。在第⑤句中,现在分词表示的动作 与谓语动词表示的动作 同时发生;在第①、③、⑨句中, 现在分词表示的动作发生在谓语动词表示的动作之前。




语态 形式

主动 语态

一般式 完成式

结构 doing
having done

表示一般性的动作,或表示的动 作与谓语动词所表示的动作同时 或几乎同时发生
表示的动作通常发生在谓语动词 表示的动作之前,特别强调动作 已经完成

语态 形式
一般式 被动 语态



being done

所表示的动作是一个正在进 行中的被动动作

having been done

表示一个被动动作发生在谓 语动词所表示的动作之前

Mary said angrily pointing to the notice. 玛丽生气地指着布告说。 Having watered the vegetables, we began to dig the ground. 我们浇过菜之后,就开始挖地。 This is the computer being repaired by Tom. 这就是由汤姆正在修的电脑。 Having been criticized by the teacher, Wang Ming gave up smoking. 受到老师的批评后,王明戒烟了。

[即时演练 1] 用所给词的适当形式填空 ① Having studied (study) English for three years, he can read brief stories in English. ② Seeing (see) the stranger coming towards him, little Jim ran away as fast as he could. ③ Having been called (call) by a stranger, he realized what would happen. ④He listened to the tape, making (make) notes now and then.

二、现在分词的句法功能 1.作定语 单个的分词作定语时一般放在被修饰词之前;现在分词短语作 定语一般放在被修饰词之后,且往往可转化为定语从句。 He brought us an interesting book. 他给我们带来了一本有趣的书。 The man sitting under a big tree is my uncle. 坐在大树下的人是我的叔叔。 The building being built now will be our dining hall. =The building which is being built now will be our dining hall. 现在正在建造的建筑将是我们的餐厅。


现在分词 它所修饰的名词通常就是现在分词的逻辑主 作定语 语,并且通常可转换成一个定语从句

动名词作 定语



??a moving truck ? ? ?a moving truck ??

正在移动的汽车?moving为现在分词, 与truck是主谓关系? 搬家汽车?moving为动名词,说明 truck的用途?

??a hunting dog ? ? ?a hunting dog ??

正在猎物的狗?hunting为现在分词, 与dog是主谓关系? 猎狗?hunting为动名词,说明dog 的用途?

[名师点津] (1)有些现在分词已经转化成形容词,它之前 常有程度副词或最高级等。常见的这种形容词化的现在分词 有:exciting, interesting, surprising, puzzling, frightening, amusing 等。
(2)现在分词的完成式(即 having done/having been done) 一般不作限制性定语。
[正] The students who have seen the film are coming out of the cinema.
[误] The students having seen the film are coming out of the cinema.

[即时演练 2]
(1)句型转换 ①Tell the boys who are playing over there not to make any noise. →Tell the boys playing over there not to make any noise. ②This is the path which leads to the school. →This is the path leading to the school.
(2)单句改错 ①There are people crying and people laugh.laugh→laughing ②The building built now will be the tallest in our city. building 后加 being

2.作表语 现在分词作表语,用来说明主语的性质和特征,相当于形 容词,其主语通常是物。一般跟在连系动词 be, get, become, look, sound, feel, keep, remain, grow, seem, appear 等后面。 Travelling is interesting but tiring. 旅行是有趣的,但也是令人疲劳的。 The news is encouraging. 这消息令人鼓舞。


现在分词 作表语

表示主语的性质和特征。不可与主语交 换位置

动名词 作表语

对主语内容的进一步说明和解释。可与 主语交换位置

比较: My job is interesting. 我的工作很有趣。(interesting 为现在分词,表示“工作” 的特征) My job is teaching. 我的工作是教书。(teaching 为动名词,它是对“工作”内 容的进一步说明)

[即时演练 3] 用所给词的适当形式填空 ①—The story that the old man told was touching (touch). —Yes, and very inspiring (inspire). ②What he said was disappointing (disappoint). ③The result of the accident is shocking (shock).

3.作补语 现在分词可以在 see, hear, notice, watch, feel, look at, listen to, observe, have, get, leave, keep, set, catch, find 等动词 (短语)后面作宾语补足语。变成被动语态时,现在分词就成了 主语补足语。 The police caught him stealing a car. 警察当场撞见他在偷汽车。 He was caught stealing a car by the police. 他偷汽车时被警察当场撞见。

I could feel my heart beating wildly. 我能够感觉到我的心在剧烈地跳动。 We noticed him swimming in the swimming pool. 我们注意到他在游泳池里游泳。 [名师点津] 在感官动词或动词短语(see, watch, observe, look at, hear, listen to, notice 等)和使役动词(have)后面的宾语 补足语常有三种形式,即不带 to 的不定式、现在分词或过去 分词。不带 to 的不定式表主动和完成;现在分词表主动和进 行;过去分词表被动和完成。

[即时演练 4] (1)用所给词的适当形式填空
①We found him waiting (wait) to receive us. ②We kept the fire burning (burn) all the time. (2)完成句子 ①她让我们在这儿等了一个小时。 She kept us waiting here for an hour. ②今天早上 10 点钟有人发现他在洗车。 He was found washing the car at ten this morning.

4.作状语 现在分词作状语,其逻辑主语是句子的主语。现在分词 作状语,是对谓语动词表示的主要动作加以修饰或作为陪衬, 也就是说现在分词表示的是比较次要的动作,是对谓语动词 表示的动作或状态的补充说明,但它们表示的动作(或状态) 是与谓语动词动作同时发生(或进行)的。现在分词作状语可 以表示时间、原因、结果、条件、让步、方式或伴随情况等。

(1)作时间状语,可以转换为 when/while 引导的时间状 语从句。
Leaving the airport (=When they left the airport), they waved again and again to us.
离开机场时,他们频频向我们挥手。 (2)作原因状语,可以转换为 because/since/as 引导的原 因状语从句。 Being league members ( = Since we are league members), we are ready to help others. 由于我们是团员,我们乐意帮助别人。

(3)作结果状语,常表示自然而然的、预料之中的结果。 可以转换为 so that 引导的结果状语从句。
He fell off the bike, hitting (=so that hit) his head against a big stone.
他从自行车上摔了下来,头撞到了一块大石头上。 [名师点津] 动词不定式作结果状语时,常表示出乎意料 的结果,而现在分词作结果状语则表示自然而然的结果。 They lifted a rock, only to drop it on their own feet. 他们搬起石头却砸了自己的脚。

(4)作条件状语,可以转换为 if 引导的条件状语从句。 Using your head (=If you use your head), you'll have a good idea. 如果你动动脑筋,你就会想出好办法来的。 (5)作让步状语,可以转换为 though/although 等引导的让步状 语从句。 Knowing (=Though/Although they knew) all this, they made me pay for the damage. 尽管他们了解了这一切,但还是要我赔偿损失。 (6)作伴随状语和方式状语,可以转换为与原句并列的一个分句。 The girls came in, following (=and followed) their parents. 那些女孩子跟在她们父母的后面进来了。

[即时演练 5] 用所给词的适当形式填空/句型转换
① Having eaten (eat) at the cafeteria before, Tina didn't want to eat there again. ② Climbing (climb) to the top of the tower, we saw a magnificent view. ③ Living (live) in the country, we had few social engagements. ④A lot of good land has gone with rain water, leaving (leave) only sand. ⑤Working very hard, he didn't feel a bit tired. → Though/Although he worked very hard, he didn't feel a bit tired.

三、现在分词的特殊结构 1.连词+现在分词 when, while, if, though, as, until, once, whether, unless, where 等连词后可接现在分词作状语,相当于这些连词引导的状语从 句,这时现在分词的逻辑主语是句子的主语。 While (=While he was) listening to the debate, he made notes. 听辩论时,他做了笔记。 If walking (=If you walk) the dog, you should be careful and don't let it get loose. 如果你遛狗,当心别松了手。

2.not +现在分词 现在分词的否定形式是在其前加 not。 Not knowing what to do next, she stopped to think. 不知道下一步做什么,她停下来思考。
Not having finished the homework, the little girl is not allowed to play outside.
由于没完成作业,这个小女孩不被允许出去玩。 3.现在分词的固定短语 有些惯用的现在分词的固定短语,在句子中可以没有逻辑
上的主语而独立存在,它们往往作为句子的独立成分来修饰全 句,表明说话者的态度、观点等,我们称这种成分为评论性状 语或评注性状语。常见的有:

generally speaking


frankly speaking


strictly speaking


honestly speaking


judging from/by ...


Generally speaking, the learned are respected by people.


Judging from his look, he didn't agree with you at all.

第五步:过渡衔接联成篇 Fighting against desertification
In recent years, desertification has gone from bad to worse and threatened us in many ways. About one fourth of the world's land surface has been replaced with desert. Worse still, it's likely that the area of desert will increase by 17% in the next century.
Survey shows that many factors contribute to the phenomenon. First, human being's bad behaviour is to blame,

such as illegal cutting, planting no trees and so on. Second,

flood and global warming have also speeded up the process.

There is no doubt that our environment will suffer a greater destruction if we let this situation continue as it is. The

following measures may stop further desertification. On the

one hand, the government should call on people to plant more trees. On the other hand, we young people should take the

responsibility to promote people's awareness of the

environmental protection. Just take an active part in the
