Go under the knife.

輕微的疾病可以用藥物來醫治，如果是比較嚴重的疾病或者受重傷，就需要動手術，英文有趣的說法叫：Go under the knife. (開刀動手術) 或者說：I need surgery/I'm going to have an operation (我需要動手術)，手術室叫做Operating room 。

對 話

Lucy: I've never been on a blind date with a doctor before. Do you think I'm in good shape?

Hale: I'm afraid you'll have to go under the knife.

Lucy: I need surgery? How can you tell just by looking at me?

Hale: I'm a plastic surgeon and I can't be seen dating someone with as many lines as you, what kind of advertisement is that?

Lucy: Well you need a transplant. A personality transplant that is.

露西：我從未試過跟醫生約會，今次是第一次, 我的身體好嗎？

赫爾：我想你得接受手術。

露西：我要動手術？你只看我外表，為何這樣說？

赫爾：我是整形外科醫生，我不能被人家看見我和一個滿臉皺紋的人談戀愛，這樣我會得到什么評價呢？

露西：你才需要做移植手術，是人格移植。

整形外科醫生對女朋友說：I can't be seen dating someone with as many lines as you. You'll have to go under the knife.（我不能被人看見和個滿面皺紋的人談戀愛。你得接受手術）。

Line是‘線條’，也可指臉上皺紋，并可作動詞，例如：(1) There are deep lines on his forehead（他額上有很深的皺紋）。(2) Round her eyes are some fine lines（她眼角有魚尾紋）。(3) His face was lined with old age/cares（歲月/憂慮在他臉上留下皺紋）。

‘皺紋’還可叫做wrinkle或furrow。Furrow本是指田間犁溝，借喻臉上皺紋，特別是額上皺紋，例如：(1) Plastic surgery can remove the wrinkles round your eyes（整型外科手術，可除去你眼角的魚尾紋）。(2) Age has etched deep furrows on his brow（歲月在他臉上刻下深深的皺紋）。

外科醫生動手術，要用手術刀(surgeon's knife)，所以under the knife（在刀下）有‘接受手術’的意思，例如：(1) He went under the knife without being anesthetized（他沒有麻醉就接受手術）。(2) He almost died under the knife（他幾乎在手術中死去）。害怕動手術，叫做to have a horror of the knife，例如：It is only natural that you should have a horror of the knife（你害怕動手術，是很正常的）。

‘外科手術’英文叫operation，動詞是operate，例如：He underwent an operation to remove a tumor/The surgeon operated on him and removed a tumor（醫生為他動手術，割去腫瘤）。
