Wh- on earth...? 究竟……
用法透視
特殊疑問句中加上"on earth"可以加強語氣，表示強調(diào)，有很強的感情色彩，意思是“究竟……；到底……”。另外，也可以用"the hell; in the world"。
支持范例
1. Why on earth do you tell a lie?
你究竟為什么要撒謊？
2. Who on the earth do you think you are anyway?
你究竟認(rèn)為你是什么人？
3. Where in the world did you find the lost watch?
你到底在哪兒找到那塊丟失的手表的？

B: I'm terribly sorry I'm late. I just couldn't help it.

A: It's really very easy saying you're sorry.

B: Look, just give me a chance. I can explain it.
你別急，給我個機會，我可以解釋！
