6. There's the Rub: 這就是問(wèn)題所在

How Shakespeare used it:

In Hamlet's famous "To be or not to be" soliloquy, "ay, there's the rub" is the tormented prince's acknowledgement that death may not end his difficulties because the dead may perhaps still be troubled by dreams. (Hamlet, Act 3, Scene 1)

莎士比亞原文：在《哈姆雷特》那句著名的“生存或者死亡”獨(dú)白中，“唉，這就是問(wèn)題所在”表示飽受折磨的王子認(rèn)識(shí)到，死亡并不能結(jié)束他的痛苦，因?yàn)樗廊丝赡苋匀粫?huì)被夢(mèng)境困擾。（《哈姆雷特》，第3幕第1場(chǎng)）

"There's the rub. What does a progressive institution like Smith [College] do when Barbara decides to become Bert? It's a problem." — Roger Kimball, The New Criterion, May 2005
