动名词与动词不定式作主语的区别1.不定式作主语经常表具体的动作，常与特定的连用。动名词作主语经常表示抽象的动作，一般不与特定的执行者连用。（动名词主要强调一种现象）。Eg.Doingexerciseisgoodforourhealth.(抽象）Todosomeexerciseisgoodforyou.（具体）Itisnotverygoodforyoutosmokesomuch.（具体）Smokingisbadforourhealth.Tosmokeisnotgoodforyou.Climbingmountainsisinteresting.Itisinterestingforhimtoclimbmountains.Drivingacarduringtherushhouristiring.(B)isagoodformofexerciseforbothyoungandold.(指现象）A.ThewalkB.WalkingC.TowalkD.Walk2.It'snogood/use/fun+doingsth.eg.It'snousetalkingtohimagain.It'snogoodeatingtoomuchfat.但如果加了执行者，应该用：It'snogoodforyoutoeattoomuchfat.3.Itisdangerousclimbingatree.Itisterriblenotbeingallowedtosmokeatall.Itisnicehelpingotherpeople.Itisinterestingplanningaholiday.但important,necessary,possible,impossible...等形容词不能用上述结构：eg:It'simportantlearningforeignlanguages.(×)It'simportanttolearnforeignlanguages.(√)4.主语与表语必须一致。Eg.Toseeistobelive.(√)Seeingisbelieving.(√)
