动词­ing形式的被动形式，在句中可以作主语、宾语、宾语补足语、定语和状语，但不能作谓语。

　　Not being allowed to go out made him very angry.

　　不让他出去，他非常生气。

　　It's fun being taken to the zoo.

　　有人带着去动物园很有趣。

　　2．作宾语

　　可接动名词的被动式作宾语的动词有admit, appreciate, avoid, consider, deny, enjoy, escape, finish, imagine, mention, mind, practise, risk, remember, forget等。

　　She doesn't remember having ever been given a chance to go abroad.

　　她不记得曾被给过出国的机会。

　　4．作宾语补足语

　　表示动作正在进行。常用在"感官动词(see, notice, find, look at, watch, hear等)＋宾语＋宾语补足语"结构中，当感官动词用于被动语态时，宾语补足语会变为主语补足语。

　　我进入村庄时，我看见很多新房子正在被修建。

　　I heard this song being sung in English then.
