A：Hey，Joe! Where have you been these past few days?嗨，乔，这些天你去哪里了?

B：I’ve been busy with a first aid course that I started about a week ago at the Red Cross.我一直忙于一周前在红十字会那里开始学的急救课程。

A：Cool! I’ve always wanted to do something like that! Have you learned anything useful?真酷，我也一直想做点那类的是。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!当然。我学会了如何按压来止血，如何来检查麦博，甚至也学了如何用心肺复苏法。

A：Have you treated any real emergencies?你治疗过紧急事故吗?

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!他们让一些护理人员带我们。有一个人从摩托上摔下来，收到了震荡，还有几处综合性骨折。他的伤很严重，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!我能想到，一看到血我就晕。所以我再也不会参加那样的课程了。
