ing分詞的用法

　　1.-ing分詞的構(gòu)成

　　-ing分詞是由動(dòng)詞原形加詞尾-ing構(gòu)成。-ing分詞同樣有時(shí)態(tài)和語(yǔ)態(tài)的變化，通常有下表幾種形式（以do為例）：

　　一般式 完成式

　　主動(dòng)形式 doing 主動(dòng)形式 having done

　　被動(dòng)形式 being done 被動(dòng)形式 having been done

　　-ing分詞的否定形式是由not 加-ing分詞構(gòu)成。如：

　　Not knowing his address, I could do nothing but stay at home and wait.

　　不知道他的地址，我只好在家里等著。

　　His not coming made all of us angry. 他沒來使我們大家都很生氣。

　　2. -ing分詞的一般式和完成式：

　　-ing分詞的一般式表示和謂語(yǔ)動(dòng)詞所表示的動(dòng)作同時(shí)進(jìn)行的動(dòng)作；完成式表示在謂語(yǔ)動(dòng)詞所表示的動(dòng)作之前發(fā)生的動(dòng)作。如：

　　Being a student, he was interested in books. 作為一個(gè)學(xué)生，他對(duì)書本很感興趣。

　　3. -ing分詞的被動(dòng)式：

　　-ing分詞的被動(dòng)式表示它的邏輯主語(yǔ)是-ing分詞動(dòng)作的承受者。根據(jù)-ing分詞動(dòng)作發(fā)生的時(shí)間，-ing分詞的被動(dòng)式有一般被動(dòng)式(being done)和完成被動(dòng)式(having been done)。如：

　　The question being discussed is very important. 正在被討論的問題很重要。

　　Having been criticized by the teacher, he gave up smoking. 被老師批評(píng)以后，他把煙戒了。 

　　注意：在need, want, require, be worth等動(dòng)詞(短語(yǔ))后，作賓語(yǔ)的-ing分詞常用主動(dòng)形式來表示被動(dòng)含義。如：

　　Your shoes need cleaning. = Your shoes need to be cleaned. 你的鞋需要清洗一下了。

　　This book is well worth reading. 這本書很值得一看。

　　1）、-ing分詞和動(dòng)詞不定式作主語(yǔ)和表語(yǔ)的主要區(qū)別在于：在表示比較抽象的一般的多次性行為時(shí)多用-ing分詞；在表示具體的或一次性的動(dòng)作，特別是將來的動(dòng)作時(shí)，多用不定式。如：

　　Smoking is forbidden here. （泛指吸煙）這里禁止吸煙。

　　3）. 有些動(dòng)詞既能接不定式，又能接-ing分詞，含義有所不同。如：

　�、賔orget, remember, regret等詞后面接不定式表示不定式動(dòng)作后于謂語(yǔ)動(dòng)作，而后接-ing分詞作賓語(yǔ)表示分詞動(dòng)作先于謂語(yǔ)動(dòng)作。如：

　　Do you remember seeing me before? 你記得以前見過我嗎？

　　Remember to lock the door when you leave. 離開時(shí)要記得鎖門。 

　　②動(dòng)詞mean, stop, try, go on等動(dòng)詞后面接分詞和接不定式作賓語(yǔ)，意思也有所不同。如：

　�、蹌�(dòng)詞allow, advise, forbid, permit等可直接跟-ing分詞作賓語(yǔ)，不可以接動(dòng)詞不定式作賓語(yǔ)，但可接不定式作賓語(yǔ)補(bǔ)語(yǔ)。如：

　　Please permit me to say a few words. 請(qǐng)?jiān)试S我說幾句話。

　　We don’t permit smoking here. 我們這兒不允許吸煙。

　　④動(dòng)詞need, require, want作“需要”解時(shí)，后面接-ing分詞或不定式的被動(dòng)式。如：

　　The room wants cleaning/to be cleaned. 這個(gè)房間需要打掃。

　　These little children require looking after carefully/to be looked after carefully.

　　這些小孩需要細(xì)心地照料。

　�、輨�(dòng)詞like, hate, prefer等后面，如表示一般性動(dòng)作，多用-ing分詞；如指特定的具體的某次動(dòng)作，多用不定式。如：

　　We began to do that job last year. 我們?nèi)ツ觊_始做那工作的。

　　They started talking about the film at once. 他們立刻開始談?wù)撃遣侩娪啊?/p>

　　注：下面幾種情況多用不定式作賓語(yǔ)：

　　When the teacher came into the room, he was starting to write to his parents.

　　老師走進(jìn)教室的時(shí)候，他正開始寫信給他的父母親。

　�、�-ing分詞作定語(yǔ)還可以表示所修飾的人或物的動(dòng)作或狀態(tài)，在意思上接近一個(gè)定語(yǔ)從句，可以表示正在進(jìn)行的動(dòng)作，也可表示經(jīng)常性動(dòng)作或當(dāng)時(shí)的狀態(tài)。如：

　　developing countries = countries that are developing 發(fā)展中國(guó)家

　　a growing city = a city that is growing 發(fā)展著的城市

　　8. 不定式和-ing分詞作賓語(yǔ)補(bǔ)語(yǔ)的區(qū)別：

　　在see, hear, feel, watch, notice等感官動(dòng)詞后，既可用-ing分詞構(gòu)成復(fù)合賓語(yǔ)，也可用不定式構(gòu)成復(fù)合賓語(yǔ)，兩者之間有一定的區(qū)別。用-ing分詞時(shí)，表示動(dòng)作正在進(jìn)行；用不定式時(shí)，表示動(dòng)作發(fā)生了，即動(dòng)作的全過程結(jié)束了。如：

　　Do you hear someone knocking at the door? (Someone is knocking at the door.) 有人在敲門你聽見了嗎？
