Hayley教口語，“冷不丁地...”用英語怎么說？

spring作動詞，其中有一個意思是to appear suddenly(突然出現(xiàn);涌現(xiàn))。

"Where did you spring from? - I didn't see you come in!"

“你從哪兒冒出來的?——我都沒見你進來!”

to suddenly tell or ask someone something when they do not expect it

突然告訴或問某人他們沒有想到的事情;突然告訴(某人);冷不防地問(某人)

I hope he's not going to spring any nasty surprises on us at the meeting this morning.

我希望今天上午的會議他不會冷不防對我們說出一些讓人討厭的話來。
