动名词与动词的名词形式有什么区别

顾名思义,动名词就是 动词变为名词,这个变化是由 动词+ ing 形成,
比如
eat=> eating
fight => fighting
run => running
动名词也有被动语态,比如
acclaim => being acclaimed
例句：
Eating is as important as breathing
Fighting has erupted in the Ukraine
Being acclaimed is the best thing that ever happened to John.动词都有名词形式吗,动名词与动词的名词形式有什么区别大部分动词有 ing 的动名词形式，例外是助动词 （比如 can, could, may, might, shall, should, will, would, must, ...)和来自古英语的动词 （比如 hath, doth, sayeth, ...）这些动词没有 ing 的动名词。动名词和动词的名词形式 在意思和用法上常有区别，但区别很细微。比如 fight 是动词， 其名词形式也是 fight ，其动名词是 fighting 。fight 和 fighting 的意思不容易区分，请看例句：Fighting has erupted between opposing factions in the country. The fight is about who gets to control the mineral resources in the region.第一个 fighting 不能用 fight 替代，第二个 fight 虽然可以被 fighting 替代， 但习惯是用 fight 。（一个原因是避免与前面的 fighting 重复。）也就是说，动词和动名词在意思上和用法的区别很难一概而言，要从多读、多听学来。所有的动词都有名词形式吗,如何分辨一个词有没有名词形式,,可不可以直接用动名词代替
