动词不定式和动名词的用法区别具体那些词用动名词,哪些用不定式,似乎都行,如：What other jobs need__

1. doing
need作为行为动词有两种用法need to do sth./ need doing sth.区别在于主语和谓语之间,一个是主动关系,一个是被动关系.
本句中,jobs是要被人do,所以job和do之间是被动关系,所以要用need doing.
2. answering
有两种解释的方法,简单的一个是,你要记住介词后面的动词永远都是动名词.因为介词后面必须是名词,动名词也是名词.另一种解释就是,熟记动词的使用方法,get tried of doing sth 尝试做某事.
3. stealing
理由同上.be accused of doing 被指控作了某事

What other jobs need_doing_?(do)
need doing=need to be done 需要被做
I got tired of_answering__so many questions.(answer)
of是介词，介词后面用动词ing形式，然后主语I和answer是主动关系，用主动形式就可以了。
The men were acc...

What other jobs need_to do__?(do)
I got tired of_answering__so many questions.(answer)
The men were accused of__stealing__money from a shop.(steal)
记住,介词后跟动名词;动词后跟不定式!

to do
answering
stealing
因为of 后只能加动名词词
动词后，加动名词还是不定式，是看固定搭配的，不同的用法和意义～

doing,因为情态动词后动词的ING形式表被动
answering,因为介词后只跟名词或动名词
stealing,因为介词后只跟名词或动名词
还有在一些情况下，动词不定式可以表目的，而动名词不行
