西部落：你的外科医生怎么准备大型手术

（单词翻译）

Y:Hey,Don.Did you have wanna be a doctor when you are a kid?

D:Yeah,I always wanna be a surgeon.

Y:So,what happend?

D:I'm afraid of blood.Plus,it’s a lot of pressure, having someone’s life in your hands. I mean one mistake and you can kill someone.

Y:Right.But you know there are things surgeons can do to cut down on mistakes. Like, for instance¹, warming up before operating.

D:You mean warming up by as streching or something?

Y:Not exactly,but sort of.Most of the time, surgeons prepare for surgery² by going over the case and thinking about the procedure³. But studies have shown that warming up by actually practicing the procedure or going through the hand motions⁴ of the surgery really helps.In one study, doctors that warmed up this way had eighty-percent fewer errors than doctors who didn’t warm up.

D:Wow,so how can the surgeons practiced on a computer simulator or something?

Y:Exactly.And many hospitals have simulators, but they’re usually tucked⁵ away in a classroom or in the basement. But if there were a practice simulator near the OR, more surgeons could take a few minutes to warm up and perform better during the real thing.

D:Cool,if I'd known about this,maybe I would have to become a surgeon.

Y:Maybe.
