1、非谓语动词之动名词一定义动名词,就是动词后加ing的形式,即doing sth.它的作用相当于一个名词,所以叫做“动名词”。动名词的否定形式在动名词前加not。二动名词ing形式的变化规则。1.一般在词尾直接加ing。2.以不发音的e结尾的动词,去掉e再加ing。3.以重读闭音节结尾,末尾只有一个辅音的动词,要双写最后一个字母后加ing。4.少数以ie结尾的动词,变ie为y,再加ing。三作用一)作主语1.动名词用作主语,谓语动词用单数。.Reading French is easier than speaking it.阅读法文比讲法语容易。Talking to him is talking

3、名词的复合结构作主语当动名词有自己的逻辑主语时,常可以在前面加上一个名词或代词的所有格,构成动名词的复合结构(这时,名词或代词的所有格做动名词的逻辑主语)。动名词的复合结构也可以在句中作主语。注意比较下面两个句子的区别与联系:I dont mind smoking here.I dont mind his smoking here.注意:在口语中,如果动名词复合结构作宾语,其中的物主代词常用人称代词宾格,名词所有格常用名词普通格来代替,但在句首做主语时不能这样来代替。【例题】翻译句子(需包含动名词相关形式):介意我用下你的电脑吗??爸爸坚决要求他的儿子上大学。.玛丽病了,使她妈妈很着急。 .他
