用英语怎么说：登山 Mountain Climbing (51)
Y: My gosh Patrick, Where are we?
P: Yang Chen. I'm taking you mountain climbing.
Y: 登山? This is scary!
P: Don't worry, I'm an expert mountain climber. I am as steady on these steep slopes as a mountain goat.
Y: 野山羊? 你倒是smell like a mountain goat.
P: Stop complaining. We're about to reach the crux of the climb.
Y: 什么是the crux of the climb?
P: Actually, the crux of something is the most difficult or important part.
Y: Oh, crux 就是问题的症结、关键、最困难的部分。
P: Exactly. Or I could say that I decided to quit my job for many reasons, but the crux of the problem was that I didn't make enough money.
Y: Right ...Patrick，我开始爬了.. .. (Scream)
P: Oh my gosh! Yang Chen fell off the side of the cliff! Yang Chen, are you OK?
Y: Patrick, please pull me back up. Hurry! 我要掉下去了。
P: Wow, you're hanging off the side of the cliff! This is going to be a real cliffhanger. Do you know what that means?
Y: Patrick, 现在不是教英语的时候。Help me!
P: One second. A cliff hanger is when a chapter of a movie or book ends without a resolution.
Y: 我知道cliff是悬崖， cliff hanger掉在悬崖上，就是留下悬念的意思。
P: Yang Chen, do you think it might be good to have a cliffhanger ending?
P: You know Yang Chen, I like the cliffhanger ending.
