動(dòng)名詞前可以有自己的邏輯主語(yǔ),作為該動(dòng)名詞所表示的動(dòng)作的發(fā)出者。用作動(dòng)名詞邏輯主語(yǔ)的詞類(lèi)有:物主代詞、名詞所有格(即名詞后加“s”,意為“...的”)、或人稱(chēng)代詞賓格。如:
his taking part in (參加)the work will help(幫助) us a lot(非常多).
we are looking forward to(期待) betty’s coming.
 she doesn’t like my father and me interfering in (干涉)her affairs(事情).

分詞也是一種非謂語(yǔ)動(dòng)詞,在句中不能單獨(dú)作謂語(yǔ),沒(méi)有人稱(chēng)和數(shù)的變化,它可以帶賓語(yǔ)、狀語(yǔ)和表語(yǔ)構(gòu)成分詞短語(yǔ)。分詞有現(xiàn)在分詞和過(guò)去分詞兩種。
1.    現(xiàn)在分詞和過(guò)去分詞的構(gòu)成
a.現(xiàn)在分詞由原形動(dòng)詞+ing構(gòu)成,
+ ing)            play (玩,扮演, 進(jìn)行比賽) - playing
(去掉末尾的e+ ing)take (拿走, 獲得,占領(lǐng))- taking
(雙寫(xiě)末尾輔音字母+ ing)stop (停止) – stopping
(把ie改為y + ing)lie (說(shuō)謊, 躺,位于)- lying

b.過(guò)去分詞分兩類(lèi),一類(lèi)是規(guī)則動(dòng)詞,由原形動(dòng)詞+ed構(gòu)成, 如:
start – started - started
excite – excited - excited
copy – copied - copied
stop – stopped - stopped
另一類(lèi)是不規(guī)則動(dòng)詞,如come, spoken, written等,需記憶。
 
不規(guī)則變化(考生需要掌握以下進(jìn)行不規(guī)則變化的動(dòng)詞)
1.動(dòng)詞原形、過(guò)去式和過(guò)去分詞完全同形
cut(切, 減少) - cut - cut
hit(打)- hit - hit
hurt(傷害) - hurt - hurt
put(放)- put - put
let(讓?zhuān)?出租)- let -let
shut(關(guān)) - shut – shut

4.動(dòng)詞原形,過(guò)去式,過(guò)去分詞形式完全不同

go(去) - went - gone

write(寫(xiě)) – wrote - written

注意:lie有規(guī)則變化和不規(guī)則變化兩種,含義不同
lie – lied - lied(說(shuō)謊)
lie – lay - lain(躺,位于)
注意:hang 有規(guī)則變化和不規(guī)則變化兩種,含義不同
hang – hanged - hanged(處絞刑)
hang - hung - hung(掛,吊)


2.    分詞的時(shí)態(tài)和語(yǔ)態(tài)
現(xiàn)在分詞有一般式和完成式,并有主動(dòng)和被動(dòng)語(yǔ)態(tài)。過(guò)去分詞則只有一種形式,現(xiàn)以動(dòng)詞study為例:
 
主動(dòng)
被動(dòng)
現(xiàn)在分詞
一般式
studying
being studied
完成式
having studied
having been studied
過(guò)去分詞
