日常生活中，意外傷害很難避免。如果我們不及時救治或者操作不當的話，很可能會對自身或者他人的身體造成傷害，所以，掌握一些急救常識非常必要。下面我們來看一段關於學習急救的對話！
A: Hey, Joe! Where have you been these past few days?
A: 嗨，喬，這些天去哪兒了？
B: I've been busy with a first aid course that I started about a week ago at the Red Cross.
B: 我一週前在紅十字會那裏參加了一個急救課程，現在在學呢。
A: Cool! I've always wanted to do something like that! Have you learned anything useful?
A: 真酷，我也一直想做點那樣的事。你學到什麼有用的東西了嗎？
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!
B: 當然。我學會了如何通過按壓來止血，如何來檢查脈搏，還學了如何用心肺復蘇法。
A: Have you treated any real emergencies?
A: 你處理過實際的緊急事故嗎？
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!
B: 他們讓一些護理人員帶我們去處理過。有一個人從摩托上摔下來，他有點腦震蕩，還有幾處複合骨折。他傷得很嚴重，所以他們必須飛速將他送往醫院，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!
A: 我能想像得到，但是我一看到血就暈，所以我想我近期應該不會去參加那樣的課的。
