H: is this seat taken?
S: no. please sit down.
H: thanks.
S: are you also going to Beijing?
H: yes, on a business trip. How about you?
S: I'm taking a vacation to visit a friend there. Have you ever been there before?
H: yes, I went there once last summer.
S: really? What did you think?
H: I think it is amazing. You can enjoy both the traditional Chinese culture as well as the vitality of a modern cosmopolitian city. The only thing I didn't enjoy was the subway.
S: was it that crowded?
H: yes. There were always so many people. After taking the subway during the rush hour, you’ll envy sardines in their cans.
S: oh, maybe I can take the bus or even rent a car.
H: that's a good idea. Wish you a great vacation!
S: thank you very much!

这儿有人吗?
没有，请坐。
谢谢。
你也是去北京的吗？
是啊，出差。你呢？
放假去看朋友。你以前去过北京吗？
去年夏天去过一次。
是吗，感觉怎么样？
挺棒的！既可以欣赏中国传统文化，又能领略现代大都市的活力，唯一美中不足的就是北京的地铁了。
是很挤吗？
是啊，总是有很多人，你要是高峰期坐的话，一定会羡慕罐头里的沙丁鱼的。
这样啊，那我还是坐公共汽车或者租辆车吧。
这主意不错，祝你玩得愉快！
谢谢！
