There's been a shake-up.

我們俗稱公司內/機構內一些重大的人事變更或大改革為地震，英文也有類似的說法：There's been a shake-up. (公司里有大改革/大變動)，或者可以說：The company has restructured. (公司改組)，人事變動有涉及升職或降職：I got promoted/demoted. (我被升職/降職)。

對 話

Rita: What's wrong? Everyone looks like they are shook up.

Shawn: The new manager has made some drastic changes.There's been a shake-up.

Rita: So lots of people have lost their jobs? That's just awful.

Shawn: No, it's much worse than that. Everyone still has a job but he's cut the morning coffee break out. We're all going through caffeine withdrawal. I can't keep my hand still at all.

莉達：為什么人人看來都心緒不寧？

尚偉：新來的經理作了重大的改革，公司里有大變動。

莉達：那么很多人被辭退嗎？真的很糟糕。

尚偉：不，比這個更糟。沒有人被辭退，只是他取消了早上的咖啡時間，人人在捱戒咖啡因之苦，我不能讓手不抖動。

尚偉的公司取消喝咖啡時間，尚偉訴苦說：There's been a shake-up. We're all going through caffeine withdrawal（有大變動，人人在捱戒咖啡因之苦）。難怪莉達說：Everyone looks like they are shook up（人人看來都心緒不寧）。

Shake-up或shakeup是名詞，指機構、制度等的改組或整頓，例如：(1) There was a company shakeup, and many lost their jobs.（公司改組，不少人失業了）。(2) The civil service needs a major shakeup.（公務員編制應大大整頓一下）。Shake up 也可以作動詞，例如：The new board of directors has shaken up the company. （新的董事會把公司改組了）。留意shake的過去式是shook，過去分詞(past participle)是shaken。

讀者也許會問：Everyone looks like they are shook up一語，are之后為什么不用分詞shaken而用Shook？原來shake up假如解作 ‘使心煩意亂’，那shake字的過去分詞作shook或shaken都可以，例如：She was badly shook/shaken up by her mother's death.（母親去世，令她心情十分惡劣）。此外shook就不可作分詞用。

以shakeup說 ‘改組’，是俗語用法；嚴謹的說法是reorganization，例如：The civil service needs a major reorganization、The new board of directors has reorganized the company。

最后說withdrawal。‘停服（興奮劑等）’英文叫withdraw，名詞是withdrawal，例如：It is difficult to withdraw from nicotine/withdrawal from nicotine is difficult（要戒掉尼古丁癮可不容易）
