Y：Wow Patrick, look at you.
P: Why are you looking at me like that? Is there anything wrong with my outfit?
Y: It's just too tight. 在办公室穿这么紧的衣服。
P: Yang Chen. For your information I'm training for cycling race. These clothes make me more visible and reduce wind resistance. You know, 减少阻力。
P: I'm training to get faster. Do you like riding bicycles?
Y: Of course I do.
P: So you do ride a bike.
Y: 不过我骑车是为了get around ， 当交通工具， not for a race， 不是为了参加比赛。你训练用什么样的自行车啊?
P: I ride a 10-speed road-bike. That means it has two gears on the front and five on the back.
Y: 我的自行车只有三个档，only three gears.
P: For going slow, slower and slowest?
Y: Very funny. Who asked for a comedian?
P: Pretty good, but I dropped my chain.
P: No, not my chin, I dropped my chain, on the bicycles' gears came off of its track, which meant I had to stop and get it back on.
Y: 你的自行车链子掉下来了。难怪你浑身是油。You look very dirty.
P: The bike chain is pretty greasy, Yang Chen.
Y: And dirty.
P: And dirty.
