B well, I am lost on something『有个问题搞不懂』. How could an airbag break your elbow? It’s a bag, just a bag to protect you. 『它是个气囊袋，一个用来保护你的袋子。』

　　【注】故意问问她，原因其实我也知道！

　　N well, because it hits with such a force『冲力』.

　　B really?

　　N a lot of people who’ve had, you know, very bad injuries『很多(出过车祸的)人，因为安全气囊受伤很重。』.

　　B with airbag?

　　N yes.

　　B I‘ve never seen an airbag『我从来没见过气囊』.

　　N the airbag can smash『打碎、击碎』you pretty bad.

　　B does it make a noise? 『(气囊爆开时)有声音么？』

　　N no, I don't.

　　B you don't? or you don't remember?

　　N I don't remember a noise as much as the smell of sulfur『硫磺』and all of that, that apparently explodes『爆炸』or something and makes it come out. I don't know the mechanics of it at all『对它的机理我一点都不明白』.

　　B was your car ruined? 『你的车毁了么？』

　　N oh, it was pretty bad.

　　N but you know, you don't think about that at that moment, you just think, oh, my god, the pain, and what about the other people in the other car.
