It's been so long意思

"It's been so long" 這句話通常用來表達一段時間的流逝，尤其是指自從上次見到某人或某事發生之後，已經過去了很長時間。這句話可以用來表達對過去時光的感慨，或者用來強調兩個事件之間的時間跨度很大。

例如：

1. 朋友好久不見，見面時可以說："It's been so long! I can't believe it's been over a year since we last saw each other."
2. 談論到以前的經歷時，可以說："It's been so long since I graduated from college. Time really flies."
3. 當提到一個期待已久的事件時，可以說："I've been waiting for this moment for what feels like forever. It's been so long."

這句話的含義取決於上下文，但總的來說，它傳達了一種時間已經過去很久的感覺。
