口语中的以下表达是怎么样区别的？
Nice to meet you.
Nice meeting you.
Peased / Glad / Happy to meet you.
Peased / Glad / Happy meeting you.
另外，下面的句子用目前时和过去时有不同吗？
It is nice to meet you. / It was nice to meet you.
I’m pleased to meet you. / I was pleased to meet you.
刘老师已经给你了非常了解的解答，但你仍不停手，硬要分个类，这说明你的学习和总结能力都有待提升。对于网友的这个问题，第一要说明的是，Nice to meet you（美式）是 It is nice tomeet you 的省略（形容词也可换成good），而 Glad to meet you（英式）是 I’m glad to meet you 的省略（形容词也可换成pleased）。网友要对第一次见面用什么，第一次见面后分手时用什么等作个分类，我试图助你分类如下：
第一次见面时可用（不定式用通常式）：
正：Nice / Good to meet you.
正：Glad / Pleased to meet you
正：It’s nice / good to meet you.
正：I’m glad / pleased to meet you.
第一次见面后分手时可用（不定式用完成式或用动名词，也可通过it was的过去时态来体现，或同时用it was与不定式完成式或动名词）：
正：Nice / Good meeting you.
误：Glad / Pleased meeting you.
正：Nice / Good to have met you.
正：Glad / Pleased to have met you.
正：It was nice / good to meet you.
正：It was nice / good meeting you.
正：It is nice / good to have met you.
正：It was nice / good to have met you.
误：I was glad / pleased to meet you.
见面和分手均可用的表达主如果：
Nice to meet you.
依据新出版的一些英语词典，Nice to meet you 也可在第一次见面后分手时用，譬如麦克米伦对Nice to meet you的使用方法说明就是：[spoken] used forgreeting someone when you meet them for the first time, or for saying goodbyeto them on that occasion.
