it is nice doing和it is nice to do有什么区别

如题所述

nice doing用于做过的事,比如道别
道别时,最好说一声:
  Nice meeting you.
  (认识你很高兴。)
  结束谈话时,说一声:
  Nice talking to you.
  (跟你谈得很开心。)
  这句话相当于It’s been nice talking to you.

nice to do就是做。。。很好的意思,不一定是没做,而是去做什么很好。
It's nice to keep healthy.
It's nice to see you again.

it 作形式主语,主要分为下列三种情况:不定式作主语、动名词作主语 和名词从句作主语。具体分析如下:
不定式作真正主语
主要用于下列句型:
⒈It + is/was + adj./n. (形容词或名词) +to do sth.
A. 名词作表语。主要有a pity,a pleasure,an idea等
如::It is a great pleasure to do this.
B. 形容词或形容词短语作表语。
1) 下列形容词:kind,good,nice,clever,wrong,right,foolish,wise,unwise,stupid,rude,careless,cruel,brave,naughty,polite,selfish等词作表语时,不定式前常可加一个由of引起的短语,来说明不定式指的是谁的情况。形容词表示不定式逻辑主语的特征,即形容词用来描述不定式行为者的性格、品行等。
如:It was foolish of you to leave school.
2) 其他形容词作表语,常见的形容词有:necessary,hardimportant,difficult,easy,possible,common等
如:It is necessary to use a short-wave radio to pick up the programmes
⒊It + v. + to do sth.
动词不定式作主语时除动词be以外,动词take,cost,need,require,make,sound,occur 等也可用it作形式主语,而把动词不定式放在后面。
如:It took us three years to complete the project.
动名词作真正主语
用于这种形式的是一些特定的形容词和名词。
It's +n.(名词或名词短语)/adj.(形容词)+ doing sth.
1)下列形容词后常用动名词作真正主语:nice,good,useless,hard,foolish,enjoyable,worthwhile
如:It is nice talking to you.
2)下列名词或名词短语作表语时常用动名词作真正主语:use,good,fun,a waste of,job,task
如:It's a waste of time doing this.

it's nice doing sth.
做了某件事真好.(事情已经做完了)
It's nice to do sth.
做某事真好(没有做,即将要做)
例:
It's nice helping you.帮助你感觉真不错(已经帮助了)
It's nice to do the job.干这份工作会很不错的(即将开始干)

有个用法:
Nice to meet you.
(初次见面时说的)
Nice meeting you(临别时说的,已经见面了)

前者表达的意思主要强调这个事情正在做,还未做完,比如IT IS NICE SEEING YOU,表示正在见面,或刚见面时打招呼时说的,接下来还是见面的过程...

后者则表达这个动作已经完成,如IT IS NICE TO SEE YOU,一般都是指见完面道别时说的话了.
