it's nice of you 语法上怎么分析 ,of you 做什么成分呢? It's nice to not meet you.这句话在语法上对不对? It,s very nice of you,中文, It's very nice of you It's nice of you to say It's nice of you to help 英语语法 It's really nice of youIt's really nice of youIt's nice of you都有这样的说法吧,想请问这儿of的用法似乎不合语法,请问如此解释为好 it is nice to have you here,it is nice of have you here 这两句语法正确吗?为什么 it's very nice of you同义句 It's very nice of you 的中文 英语 it's very nice of you的回答 It's very nice of you 改为同义句 it's very nice of you ----(say) so It's really nice of you.Nice to meet you.区别 It's very nice ( )you. That's nice of you It's nice of you to come here,帮忙分析一下这句话的语法结构I want to go to school 还有这句的. it's very nice of you.同意句 以 it‘s very ____ ____you.填写
