I'll get back to you
We use this expression to say that we need to find some information or do something and will contact the person later.
我們用這個表達來表示我們需要找到一些信息或做某事，稍后會聯(lián)系這個人。
其中得back也就表示了是與某人得再次交談，back得原因是因為之前你缺失了某些信息或者時間不足導(dǎo)致你們上次得交流并沒有完成。等你掌握了消息之后，你就會get back to sb. 除此之外也不排除有人會把這句話當作拒絕得委婉表達，當面不給你消息，以后再說。可以翻譯作“稍后我給您回話、再跟你說、回頭跟你說、等……告訴你”。
與以下幾個表達同義：
I'll let you know.
I'll respond to you soon.
As soon as I know the answer, I will tell you.
A: Can you tell me how many students are taking the exam next month?
你能告訴我下個月有多少學(xué)生參加考試么?
B: I'll find out. I'll get back to you.
我會查清楚回頭告訴你。
