我们在一起两年了用英语怎么说

"We've been together for two years"是用英语表达"我们在一起两年了"的正确方式。

"We've"是"we have"的缩写形式，表示"我们已经"。 "Been"是动词"be"的过去分词，表示经历。 "Together"是副词，表示"在一起"。 "For"是介词，表示"达到了"。 "Two years"是名词短语，表示"两年"。

下面是几个例句：

We've been together for two years now. (我们已经在一起两年了。)
I can't believe we've been together for two years already. (我不敢相信我们已经在一起两年了。)
It's been two years since we first started dating. (我们第一次约会已经两年了。)
