我们很久没见面了用英语怎么说

标准的

Answer 1

It's a long time since we last met.( 常用）

It's been a while we haven't seen each other.（美国人喜欢用it's been a while.....)

Long time no see.(最口语，最常用，并且滑稽的是，这是chinglish被english借鉴的一句话，最开始由中国人说，然后被流传开来）

We haven't seen each other for long.( 书面语）

Answer 2

long time no see.

Answer 3

Long time no see（比较口语化）

We haven't seen each other for times。标准用语

Answer 4

Long time no see 是chinglish，就是中国式英文，不太地道
应该用“I haven't seen you for ages"

Long time no see 或者

We haven't seen each other for a long time
