一、V-ing形式作主語(yǔ)

1. 動(dòng)名詞作主語(yǔ)時(shí)，表示一般行為，謂語(yǔ)動(dòng)詞用單數(shù)。如：

Joan?s being married to Mike made her parents very angry. 瓊和麥克的結(jié)婚使她的父母很生氣。

Collecting information is very important to businessmen. 搜集信息對(duì)于一個(gè)商人來(lái)說(shuō)是非常重要的。

Doing morning exercises is good for health. 做早操對(duì)健康有好處。

Seeing is believing. 眼見(jiàn)為實(shí)。

2. 在下面的句型中，it是形式主語(yǔ)，動(dòng)名詞作真正的主語(yǔ)：It?s no use / good+V-ing.;It?s a waste of time / so nice / foolish interesting / doing sth.。如：

It?s no good smoking; you?d better give it up. 吸煙有害健康，你最好戒煙。

It?s no use arguing with him. 和他爭(zhēng)論是沒(méi)有用的。

It?s a waste of time waiting here. 在這里等是浪費(fèi)時(shí)間。

It?s so nice talking to you. 很高興和你談話。

3. There is no +動(dòng)名詞。如：

There is no telling what will happen. （試比較：It is impossible to tell what will happen.） 不知道會(huì)發(fā)生什么。

There is no joking about it. 這事開(kāi)不得玩笑。

4. 動(dòng)名詞作主語(yǔ)時(shí)與不定式的區(qū)別：

不定式作主語(yǔ)表示具體某一次的行為;動(dòng)名詞作主語(yǔ)表示抽象或泛指的動(dòng)作。實(shí)際運(yùn)用中一般可互換，差異不大，但下列幾種情況除外：

① 當(dāng)表語(yǔ)是動(dòng)名詞時(shí)，主語(yǔ)也要用動(dòng)名詞;當(dāng)表語(yǔ)是不定式時(shí)，主語(yǔ)也要用不定式。如：

Seeing is believing. （To see is to believe.） 眼見(jiàn)為實(shí)。

② 在It?s no use / no good / a waste of time doing sth.等句型中一般用動(dòng)名詞，而不用不定式。如：

It is no good keeping this secret. 此事不公開(kāi)沒(méi)有什么好處。

It is a waste of energy arguing with her. 和她爭(zhēng)論是浪費(fèi)精力。

③ 在It is important / necessary / easy to do sth.，It is+adj.+for （of） sb.+to do sth.等句型中通常只能用不定式，而不使用動(dòng)名詞。如：

It is important for you to learn English well. 對(duì)你來(lái)說(shuō)學(xué)好英語(yǔ)很重要。

It is very kind of you to help us. 你能幫助我們真是太好了。

二、V-ing形式作賓語(yǔ)

1. 在suggest， finish， admit， advise， avoid， can?t help， consider， delay， deny， endure， enjoy， escape， excuse， finish， leave off， mind等動(dòng)詞后面通常接動(dòng)名詞作賓語(yǔ);在hate， like， prefer等動(dòng)詞后面，如果表示一般傾向，則多用V-ing作賓語(yǔ)，如果指特定的或某次具體的行動(dòng)，則多用不定式。如：

He finished reading the book yesterday. 他昨天讀完了那本書(shū)。

She suggested going there to help the farmers. 她建議去那里幫助農(nóng)民。

She prefers walking to cycling. 她寧愿步行，也不愿騎自行車。

2. V-ing形式也可用作介詞的賓語(yǔ)。如：

He apologized to the teacher for being late. 他因遲到而向老師道歉。

Her family are all proud of having such a splendid house. 她的家人都為擁有如此豪華的房子而感到驕傲。

【注意】用作介詞to的賓語(yǔ)時(shí)，極易與不定式發(fā)生混淆，此類結(jié)構(gòu)還有：in addition to除……外，admit to承認(rèn)，devote oneself to獻(xiàn)身于，be equal to能勝任;等于，be familiar to為……所熟悉，give one?s mind to專心于，keep to堅(jiān)持，look up to尊敬，lead to導(dǎo)致，look forward to盼望，object to反對(duì)，pay attention to注意，point to指向，stick to堅(jiān)持，be used to習(xí)慣于，turn to求助于等。如：

[正] Let?s get down to repairing the machine.

[誤] Let?s get down to repair the machine.

3. forget， remember， stop， regret， try， mean等動(dòng)詞后跟不定式與動(dòng)名詞意義不同，不定式表示謂語(yǔ)動(dòng)詞之后的動(dòng)作，而動(dòng)名詞表示的動(dòng)作發(fā)生在謂語(yǔ)動(dòng)詞之前，常用一般式doing代替完成式having done。如：

① stop doing sth. 停止正在做的事情;stop to do sth. 停下來(lái)去做另一件事。如：

He was having a walk when he saw me. He stopped to say hello to me. 見(jiàn)到我時(shí)他正在散步，他停下腳步跟我打招呼。

The students stopped talking when the teacher came in. 當(dāng)老師進(jìn)來(lái)時(shí)學(xué)生停止講話了。

② forget后面接不定式與動(dòng)名詞，意思有很大的不同，要注意二者的區(qū)別。forget to do sth.意思為“忘記去做某事”，指尚未發(fā)生的動(dòng)作;forget doing sth. 意思是“忘記了曾經(jīng)做過(guò)的某事”，表示已經(jīng)發(fā)生了的動(dòng)作。如：

He forgot to lock the door. 他忘記了鎖門。（門沒(méi)有鎖）

He forgot locking the door. 他忘記已把門鎖上了。（門鎖上了，但是他忘記了）

③ try doing sth. 試一試做某事;try to do sth. 努力/ 盡力去做某事。如：

He was afraid to tell the truth. 他不敢把實(shí)情講出來(lái)。

⑤ go on doing sth. （停頓以后）繼續(xù)做原來(lái)做的事;go on to do sth. 接著做另一件事，指接下去做與原來(lái)不同的事。如：

Now let?s go on reading Lesson 1. 讓我們繼續(xù)讀第一課。

After reading the text， the students went on to listen to the teacher carefully.讀完課文以后，同學(xué)們接著認(rèn)真聽(tīng)老師的課。

⑥ regret doing sth. 后悔做了某事（也可以說(shuō)：regret having done sth.）;regret to do sth.（tell / say / inform）很遺憾地要做（告訴……/說(shuō)……/ 通知……）。如：

I regret to say that you have failed the exam. 很遺憾你考試沒(méi)有通過(guò)。

⑦ remember doing sth. 想起已經(jīng)做過(guò)的事情;remember to do sth. 記住要去做某事。如：

I don?t remember meeting him. 我不記得見(jiàn)過(guò)他。

⑧ mean doing sth.的意思是“意味著（必須要做某事或?qū)е履撤N結(jié)果）”，其主語(yǔ)通常是指事物的詞;mean to do sth.的意思是“打算或企圖做某事”，其主語(yǔ)通常是表示人的名詞或代詞，其過(guò)去完成式表示“本來(lái)打算做某事”。如：

Being a student means studying hard. 作為一個(gè)學(xué)生，（意味著）你要努力學(xué)習(xí)。

A friend indeed means helping others for nothing in return. 真正的朋友意指不圖回報(bào)地幫助別人。

4. 動(dòng)名詞作need， want， require， be worth的賓語(yǔ)時(shí)，用主動(dòng)式代替被動(dòng)式。如：

The point wants referring to. 這一點(diǎn)要提到。

This English novel is worth reading. 這本英文小說(shuō)值得一讀。

The situation in Russian required studying. 俄國(guó)形式需要研究。
