Go under the knife.

轻微的疾病可以用药物来医治，如果是比较严重的疾病或者受重伤，就需要动手术，英文有趣的说法叫：Go under the knife. (开刀动手术) 或者说：I need surgery/I’m going to have an operation (我需要动手术)，手术室叫做Operating room 。

对 话

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：我从未试过跟医生约会，今次是第一次, 我的身体好吗？

赫尔：我想你得接受手术。

露西：我要动手术？你只看我外表，为何这样说？

赫尔：我是整形外科医生，我不能被人家看见我和一个满脸皱纹的人谈恋爱，这样我会得到什么评价呢？

露西：你才需要做移植手术，是人格移植。

整形外科医生对女朋友说：I can’t be seen dating someone with as many lines as you. You’ll have to go under the knife.（我不能被人看见和个满面皱纹的人谈恋爱。你得接受手术）。

Line是‘线条’，也可指脸上皱纹，并可作动词，例如：(1) There are deep lines on his forehead（他额上有很深的皱纹）。(2) Round her eyes are some fine lines（她眼角有鱼尾纹）。(3) His face was lined with old age/cares（岁月/忧虑在他脸上留下皱纹）。

‘皱纹’还可叫做wrinkle或furrow。Furrow本是指田间犁沟，借喻脸上皱纹，特别是额上皱纹，例如：(1) Plastic surgery can remove the wrinkles round your eyes（整型外科手术，可除去你眼角的鱼尾纹）。(2) Age has etched deep furrows on his brow（岁月在他脸上刻下深深的皱纹）。

外科医生动手术，要用手术刀(surgeon’s knife)，所以under the knife（在刀下）有‘接受手术’的意思，例如：(1) He went under the knife without being anesthetized（他没有麻醉就接受手术）。(2) He almost died under the knife（他几乎在手术中死去）。害怕动手术，叫做to have a horror of the knife，例如：It is only natural that you should have a horror of the knife（你害怕动手术，是很正常的）。

‘外科手术’英文叫operation，动词是operate，例如：He underwent an operation to remove a tumor/The surgeon operated on him and removed a tumor（医生为他动手术，割去肿瘤）。
