日常生活中，意外伤害很难避免。如果我们不及时救治或者操作不当的话，很可能会对自身或者他人的身体造成伤害，所以，掌握一些急救常识非常必要。下面我们来看一段关于学习急救的对话！

A: Hey, Joe! Where have you been these past few days?

A: 嗨，乔，这些天去哪儿了？

B: I've been busy with a first aid course that I started about a week ago at the Red Cross.

B: 我一周前在红十字会那里参加了一个急救课程，现在在学呢。

A: Cool! I've always wanted to do something like that! Have you learned anything useful?

A: 真酷，我也一直想做点那样的事。你学到什么有用的东西了吗？

B: For sure! I mean we've learned how to apply pressure to stop bleeding, how to check for a pulse, and even how to apply CPR!

B: 当然。我学会了如何通过按压来止血，如何来检查脉搏，还学了如何用心肺复苏法。

A: Have you treated any real emergencies?

A: 你处理过实际的紧急事故吗？

B: Well, they took us along with some paramedics. There was this guy who fell off his motorcycle and suffered a concussion as well as a couple of compound fractures. His wounds were pretty serious so they had to rush him to the hospital. It was intense!

B: 他们让一些护理人员带我们去处理过。有一个人从摩托上摔下来，他有点脑震荡，还有几处复合骨折。他伤得很严重，所以他们必须飞速将他送往医院，真是很紧急。

A: I can imagine! I tend to faint when I see blood, so I think I won't be taking up a course like that anytime soon!

A: 我能想象得到，但是我一看到血就晕，所以我想我近期应该不会去参加那样的课的。
