hit someone with a problem 讓某人面對問題

I’m sorry to hit you with this problem. I don’t know who else to turn to. 很抱歉把這個問題拋給你，我不知道還可以找誰求助。

Every time they hit a problem, they will learn something important. 每當他們解決一個問題，他們就會學到一些重要的東西。

Nevertheless, as I discovered, it also helps to be able to contact a techie expert when you hit an unexpected problem such as navigating a way through a security firewall. 然而我發現，當你碰到意外問題時，比如要設法通過一個安全防火牆，這些設備還能幫你聯絡技術專家。
