a.当表语是动名词时，主语也要用动名词；当表语是不定式时，主语也要用不定式，如：Seeingisbelieving.Toseeistobelieve.在实际运用中，动名词和不定式一般可以互换，差异不大。b.动名词和不定式作主语，一般都可以使用形式主语it，而将动名词或不定式放在句尾。It’snousedoing…It’sawasteoftimedoing…例如：It’snousegoingtheretodayIt’sawasteoftimearguingaboutit.而在It’simportant…/It’snecessary…这类句型中，只能用不定式，如：It’simportanttolearnforeignlanguages.It’squitenecessarytoreaditmanytimes.b.动名词和不定式作主语，一般都可以使用形式主语it，而将2)V-ing形式作表语

能用动名词作宾语的动词有两类：B.

在need,want,deserve等后，可用动名词的主动式表示被动含义，（这时主语一般是物），如：TheflowersneedwateringTheflowersneedtobewateredC.
