一.动名词:动名次有名词和动词的特征,可以带宾语或受状语的修饰。动名词加宾语或状语构成动名词短语。
二.形式
一般式:doing(主动)、being done(被动)
完成式:having done(完成式)、having been done(被动)
例:I went to the party without being invited。
He was praised for having finished the work。
I don‘t mind being left at home。(I位于主语的位置,但充当逻辑宾语,所以用被动式)
Leave sb at home留某人在家
三.动名词可在句中充当的成分:主语、表语、宾语、定语
1.主语
例:Learning new words is very useful to me。对我来说学习生词很有用。
特殊用法:
(1)it做形式主语:
It fun/nice/(adj。) 动名词
注:在essential(必要的),important,necessary后面不可用动名词。
(2)There is no 动名词短语=It is impossible to do……
2.表语
例:My favourite sport is swimming。
