How's going?

Question

---Hi, Tom, How's going?
---___________.We are having a great time in Shanghai Disneyland.
A. It's a good idea. B. Pretty good. C. What a pity! D. Terrible.
这道题，要说选项我肯定知道选B。但有How' s going? 这种说法？我怎么记得是“How is it going?" "How are you going?"

Answer 1

这是口语简化表达，相当于how is your holiday going?因为对话双方都知道主语指的是假期，所以口语就省略了，望采纳
