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

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紅十字會那里開始學的急救課程。

A：Cool! I’ve always wanted to do something like that! Have you learned anything useful?真酷，我也一直想做點那類的是。你學到什么有用的東西了嗎?

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!當然。我學會了如何按壓來止血，如何來檢查麥博，甚至也學了如何用心肺復蘇法。

A：Have you treated any real emergencies?你治療過緊急事故嗎?

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!他們讓一些護理人員帶我們。有一個人從摩托上摔下來，收到了震蕩，還有幾處綜合性骨折。他的傷很嚴重，所以他們必須飛速將他送往醫(yī)院，真是很緊急。

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，一看到血我就暈。所以我再也不會參加那樣的課程了。
