動(dòng)詞V-ing形式在句中可以作主語、賓語、表語、定語、賓語補(bǔ)足語以及狀語。今天我們主要研討一下其作定語和表語的用法：

一、V-ing形式作定語

1. 單個(gè)的動(dòng)詞V-ing形式作定語，通常位于所修飾詞之前。例如：

boiling water， the rising sun， the surprising news， the moving blackboard

Which class does the shouting boy come from？ 那個(gè)大喊大叫的男孩來自哪個(gè)班？

2. 由動(dòng)詞V-ing形式構(gòu)成的短語作定語，只能位于所修飾詞之后。例如：

Who is the girl following our English teacher all the way？ 一直跟在我們英語老師身后的那個(gè)女孩是誰？

The boy having seen the accident said that the car knocked the man off his bike. 看見事故的那個(gè)男孩說那輛車把那個(gè)人從自行車上撞落下來。

現(xiàn)在分詞作定語，相當(dāng)于定語從句的省略，上述三句可補(bǔ)全如下：

Which class does the boy that is shouting come from？

Who is the girl that followed our English teacher all the way？

The boy who had seen the accident said that the car knocked the man off his bike.

3. V-ing形式作定語，還可表示所修飾詞語的用途，可換用for表示。例如：

a sleeping car = a car for sleeping 臥鋪車廂

a sleeping pill = a pill for sleeping 安眠藥丸

a walking stick = a stick for walking 拐杖

a swimming pool = a pool for swimming 游泳池

當(dāng)然，V-ing形式作定語更多的時(shí)候說明的是所修飾詞的性質(zhì)、特征、所處的狀態(tài)等。例如：

a sleeping dog = a dog that is sleeping正在睡覺的狗

a walking man = a man who is walking正在走路的男子

4. 另外，V-ing形式作定語時(shí)，容易和V-ed分詞發(fā)生錯(cuò)用。V-ing形式有“主動(dòng)”或“進(jìn)行中”之意，V-ed分詞則表示“被動(dòng)”或“已完成”。試比較如下：

She is the student representing her school to attend the conference. （表示主動(dòng)） 她是代表她學(xué)校參會(huì)的那個(gè)學(xué)生。

I think youd agree hes a respected columnist. （表示被動(dòng)） 我想你得承認(rèn)他是個(gè)備受尊敬的專欄作家。

You cant drink boiling water. You can drink boiled water. 你不能飲用滾燙的水，你可以飲用（涼）開水。（V-ing形式表進(jìn)行中，V-ed分詞表已完成）

二、V-ing形式作表語

V-ing形式作表語可分兩種情況：1. 相當(dāng)于形容詞;2. 相當(dāng)于名詞。例如：

English is quite interesting. （interesting相當(dāng)于形容詞）

Her job is teaching English. （teaching English相當(dāng)于名詞）

第一種情況，應(yīng)注意其與過去分詞的區(qū)別。V-ing形式表示“主動(dòng)”之意，V-ed分詞則表示“被動(dòng)”。試比較如下：

This news is really disappointing. We are all disappointed at the news. 這個(gè)消息真地很令人失望。我們對(duì)這個(gè)消息都很失望。（V-ing形式表主動(dòng)，V-ed分詞表被動(dòng)）

第二種情況易與進(jìn)行時(shí)結(jié)構(gòu)相混，可從以下兩個(gè)方面予以區(qū)別：

1. 看主語是否是V-ing動(dòng)詞的執(zhí)行者（即V-ing動(dòng)詞的動(dòng)作是否是句子主語的動(dòng)作）。是則為進(jìn)行時(shí)，不是則為V-ing形式。例如：

1） He is cleaning the street. 他正在打掃街道。

2） His job is cleaning the street. 他的工作是打掃街道。

例1中的clean是主語he的動(dòng)作，為進(jìn)行時(shí)。例2中的clean顯然不是his job的動(dòng)作，為V-ing形式。

2. 看V-ing動(dòng)詞（結(jié)構(gòu)）能否與主語對(duì)換位置。能則為V-ing形式，不能則為進(jìn)行時(shí)。例如：

3） The most difficult problem is building the bridge base. 最困難的問題是建造橋基。

4） They are building the bridge base. 他們正在建造橋基。

例3可以調(diào)整為：“Building the bridge base is the most difficult problem.”，故為V-ing形式。而例4則不能（Building the bridge are they. 不正確），故為進(jìn)行時(shí)。
