Ⅰ動(dòng)名詞的定義
動(dòng)名詞也是動(dòng)詞的三種非謂語形式（不定式、分詞、動(dòng)名詞）中的一種。與分詞和不定式一樣，它也不能在句子中單獨(dú)作謂語。動(dòng)名詞具有名詞和動(dòng)詞的特征，可以帶賓語或狀語修飾。在句子中，動(dòng)名詞可作主語、表語、賓語、定語、補(bǔ)語和同位語等。此外，動(dòng)名詞還可以通過加賓語或狀語構(gòu)成動(dòng)名詞短語。
Ⅱ動(dòng)名詞的基本形式
動(dòng)名詞由動(dòng)詞原形加詞尾-ing構(gòu)成，構(gòu)成與現(xiàn)在分詞形式相同。它還有下面幾種形式：
主動(dòng)語態(tài) 被動(dòng)語態(tài)
一般式 doing being done
完成式 having done having been done
Ⅲ動(dòng)名詞的句法功能
動(dòng)名詞在句中起名詞的作用，可單獨(dú)出現(xiàn)或組成短語作主語、表語、賓語、介詞的賓語、定語和同位語。
1.作主語
Seeing is believing.
Being a teacher was by no means easy.做老師決非易事。
His having left early made everyone feel very disappointed. 他的提前離開使得每個(gè)人都非常失望。
It was a nuisance being kept waiting like that.被弄得這樣等著真討厭。
★○1It was no use/of little use/no good/useless /a waste of time/a waste of money/a great pleasure/fun + doing sth.(it為形式主語)
It was no use talking it over with him.跟他討論此事沒有用。
It was no use crying over the spilt milk.覆水難收。（木已成舟，哭也沒用）
It is of little good staying up too late every day.每天都熬夜沒有什么好處。
○2There was no….結(jié)構(gòu)中只能用動(dòng)名詞，表示禁止和不可能。

2.作表語
Boasting was cheating.說大話等于欺騙。
A bad habit was reading without thorough understanding.一種壞習(xí)慣是讀書而不求甚解。
★動(dòng)名詞擔(dān)任表語說，和進(jìn)行時(shí)態(tài)完全相同，但兩者性質(zhì)不一樣，且意義也不一樣。
He was teaching English.他正在教英語。（was teaching為現(xiàn)在進(jìn)行時(shí)態(tài)，was teaching English為謂語部分）
His job was teaching English.他的工作是教英語。(teaching為動(dòng)名詞，was teaching English為系表結(jié)構(gòu))
3.作賓語
He was considering collecting stamps.他在考慮集郵。

Do you think it any good asking him for advice? 你認(rèn)為向他征求建議有好處嗎？

★○1英語中有些動(dòng)詞：admit, allow, appreciate, avoid, advise, consider, deny, delay, dislike, enjoy, escape, excuse, finish, imagine, keep, mind, miss, practise, recommend, risk, permit, suggest等，以及某些短語：can’t help(情不自禁)，feel like, devote to, stick to, object to, thank you for, get down to, have difficult/trouble (in), have a good/wonderful/hard time (in), look forward to, give up等后面只跟動(dòng)名詞。

c.f.: -----Would you mind closing the window? 請(qǐng)你把窗子關(guān)起來你介意嗎？

○3有些詞或詞組：can’t help, stop, be used to, regret, go on, remember, forget, mean, try等既可以跟不定式也可以跟動(dòng)名詞，但意義不同。
○4動(dòng)詞like, love, prefer后接不定式或動(dòng)名詞作賓語均可。如表示經(jīng)常性的行為可用動(dòng)名詞，如表示具體的行為常用動(dòng)詞不定式。但要注意：如果like, love, prefer前有would/should, 后面則應(yīng)接動(dòng)詞不定式。

I’d like to go swimming this weekend.
○5在動(dòng)詞allow, advise, forbid, permit等動(dòng)詞后直接跟動(dòng)名詞形式作賓語，如果后面有名詞或代詞作賓語，其后用動(dòng)詞不定式作賓語補(bǔ)足語。即：
allow/ advise/ forbid/ permit

5.作定語

In class we should write down important teaching points as well as difficult teaching points.
課堂上我們應(yīng)當(dāng)將教學(xué)重點(diǎn)和難點(diǎn)記下來。
★ 現(xiàn)在分詞和動(dòng)名詞一樣都能作定語，但是有區(qū)別：
Look at the flying planes.瞧那些飛著的飛機(jī)。（現(xiàn)在分詞）
Flying planes was dangerous.開飛機(jī)有時(shí)危險(xiǎn)。（動(dòng)名詞）
★ 分詞與所修飾的詞邏輯上是主謂關(guān)系，動(dòng)名詞與所修飾的詞只表示被修飾的詞的目的或作用關(guān)系。
a sleeping child = a child that was sleeping
a waiting room = a room for waiting
★動(dòng)名詞還能和介詞一起構(gòu)成短語，作定語：intention (of), way of (of), right (of), capability (of), chance (of), plan (of), hope (of), possibility (of), significance (of), necessity (of), surprise (of), apology (for), experience (in)….
有些詞：chance, plan, intention, way等后面既可以接動(dòng)名詞也可以接不定式作定語。
This was the best way to do the work/ of doing the work.這是做這種工作的最佳方法。
6.作同位語
Many people admire his special ability, learning three languages at the same time.
他能同時(shí)學(xué)三種外語，許多人都羨慕他這中特殊能力。
Ⅳ動(dòng)名詞的復(fù)合結(jié)構(gòu)
物主代詞和名詞所有格加動(dòng)名詞構(gòu)成動(dòng)名詞的復(fù)合結(jié)構(gòu)。在這個(gè)結(jié)構(gòu)中，物主代詞或名詞所有格是邏輯上的主語。動(dòng)名詞的復(fù)合結(jié)構(gòu)在句中可以作主語、賓語等。
Your being elected to be monitor of the class was possible.你當(dāng)選為班長是可能的。
Your translating the article pleased him very much.你翻譯那篇文章使他大為開心。
★如果不是在句子開頭，這個(gè)結(jié)構(gòu)常可以用名詞的普通格（或人稱代詞的賓格），這比用所有格自然些。
Do you mind my (me) smoking? 介意我抽煙嗎？
Peter’s going won’t be of much help. Peter去不會(huì)有多大幫助。
★如果動(dòng)名詞的邏輯主語是無生命的東西，就多用普通格，不用所有格。
We know of wood having been used as building materials since ancient times.我們知道一些木材自古代就一直被用作建筑材料。
We have heard of some minerals having been taken from the ocean.我們聽說過一些從海洋里提取出的礦物質(zhì)。
Ⅴ動(dòng)名詞的時(shí)態(tài)和語態(tài)
㈠動(dòng)名詞的時(shí)態(tài)
1. 動(dòng)名詞的一般時(shí)：它表示的動(dòng)作與謂語動(dòng)詞表示的動(dòng)作同時(shí)發(fā)生，或在謂語動(dòng)詞表示的動(dòng)作之后發(fā)生。
Children like watching cartoon films.兒童喜歡看動(dòng)畫片。
Thank you for lending us a helping hand.謝謝你向我們伸出援助之手。
★ 在某些動(dòng)詞后，動(dòng)名詞所表示的動(dòng)作雖然發(fā)生在謂語動(dòng)詞表示的動(dòng)作之前，但這是仍可用動(dòng)名詞的一般式。
I remember being taken to Beijing when I was young.我記得小時(shí)曾被帶到過北京。
I forgot posting the letter then. So I am here again. 我忘記信已經(jīng)寄掉了，所以我又來了。
2. 動(dòng)名詞的完成式：它所表示的動(dòng)作發(fā)生在謂語動(dòng)詞表示的動(dòng)作之前。
He admitted having taken some cash from the drawer.他承認(rèn)從抽屜里拿了一些現(xiàn)金。
He was proud of having ever played a minor role in a play.他對(duì)自己曾在一本劇本里扮演過一個(gè)次要角色很自豪。
㈡動(dòng)名詞有被動(dòng)語態(tài)
動(dòng)名詞有兩種被動(dòng)語態(tài)：一般式（being done）和完成式（having been done）
★ 如果一個(gè)動(dòng)名詞邏輯上的主語所表示的是這動(dòng)作的對(duì)象時(shí)，動(dòng)名詞一般要用被動(dòng)形式。
He came without being invited. 他是不請(qǐng)自來的。
I can’t stand being treated this way.這樣待我我受不了。
It’s impossible to come into a room without being asked. 沒有被邀請(qǐng)就闖入房間是不禮貌的。
★ 如果動(dòng)名詞表示的動(dòng)作在謂語表示的動(dòng)作之前發(fā)生，有時(shí)需要用動(dòng)名詞的完成被動(dòng)形式。
I don’t remember having met you before.我不記得以前曾見過你。
There was no proof of his having said that. 沒有證據(jù)表明他曾那樣說過。
Yesterday, he informed us of the bridge having been completed.昨天，他告訴我們大橋已經(jīng)完工了。
Ⅵ動(dòng)名稱的否定式以及動(dòng)名詞和動(dòng)詞不定式的區(qū)別
動(dòng)名詞和動(dòng)詞不定式的區(qū)別：從結(jié)構(gòu)上，動(dòng)名詞前可用介詞，它還可被名詞所有格修飾；不定式前通常不用介詞，更不能被名詞所有格修飾。
動(dòng)名詞和不定等都可以作主語或表語。一般來說，在表示比較抽象的一般行為時(shí)多用動(dòng)名詞；在表示具體的動(dòng)作，特別是將來的動(dòng)作時(shí)，多用不定式。
Reading was learning.閱讀就是學(xué)習(xí)。
Our work was to learn more knowledge and serve the people better in the future.
我們的任務(wù)就是學(xué)習(xí)更多的知識(shí)將來更好地為人民服務(wù)。
★ 如果牽涉到主語和標(biāo)語一致時(shí)，往往同為動(dòng)名詞或同為不定式。
Seeing is believing. = To see is to believe.
Ⅶ 動(dòng)名詞和現(xiàn)在分詞在句法上的區(qū)別
1. 作定語時(shí)的比較
現(xiàn)在分詞作定語，表示它所修飾的名詞的動(dòng)作，被修飾名詞與現(xiàn)在分詞在邏輯上是主謂；動(dòng)名詞作定語時(shí)往往表示被修飾名詞的作用、目的等。
running dogs= dogs that run their masters’ errands走狗
a walking stick= a stick that was carried in the hand during a walk拐杖
a sleeping car= a car that was used for sleeping臥車
a sleeping baby= a baby that was sleeping熟睡的嬰兒
2. 作表語時(shí)的比較
動(dòng)名詞作表語是用來說明主語本身的，主語和標(biāo)語的位置互換后基本不影響意義的表達(dá)，但這種結(jié)構(gòu)不能受very, quite等副詞修飾。分詞作表語著重說明主語的性質(zhì)和特征，主語和表語的位置是固定的，一般不能互換，但可受very, quite等副詞的修飾。
My job was serving you. (=Serving you was my job.)我的工作是為您服務(wù)。
The story was very exciting.那個(gè)故事很刺激。
Ⅷ名詞化的動(dòng)名詞
動(dòng)名詞有時(shí)可以進(jìn)一步名詞化，具有更多名詞的特點(diǎn)：它可以受冠詞的限制，可以受定語修飾，有時(shí)還有復(fù)數(shù)形式。
What do you think of the drawing? 你覺得我的畫如何？
How does he make a living? 他是怎么謀生的？
I like reading the story with a happy ending.我喜歡讀愉快結(jié)尾的小說。
Just as the saying goes, an apple a day keep a doctor away.正如常言所說，一只蘋果一天，不沾醫(yī)生的邊。
