怎么正确说: It's already been two years since I last studied Chinese?
“现在已经过了两年没学习中文了”？

Question

Answer

我已经有两年没学中文了。

Answer

最后一次学习中文是两年前的事了。

我有两年没有学习中文了。

Answer

It's already been two years since I last studied Chinese -> 我学习中文已经有两年多了。
Rong's answer carried the opposite meaning  我已经有两年没学中文了 -> I have not studied Chinese for two years already.

Answer

It's already been two years since I last studied Chinese?
It's already been two years已经过去了两年了
since I last studied Chinese? 自从我上次学习汉语

直接翻译就是：我已经两年没学习汉语了。
