情景对话
　　Lele:Wow! This subway station is really nice! Look, there's a man playing the saxophone! Isn't that romantic? 　　Bobbie:Uh-huh. It seems like the music is just for us. 　　K K:Oh, please stop. My day pass has gone. 　　Bobbie:Gosh! This is typical. You'd better repay for it, or you would be fined 25o dollars if you were caught fare-beating. 　　Bobbie: Here comes the train. I hope it won't be too crowded today. 　　K K: Hey! Get behind the yellow line or the train will hit you. 　　Lele: Oops!I wasn't watching where I was standing. 　　Bobbie: Be careful! Subway doors open and close automatically. 　　K K: Yes, it's somehow dangerous. Last time my hand was pinched between the subway doors. It still hurts. 　　Lele: Oh, God! So many people ride the sub-way! It is crowded. 　　K K: After you have ridden on a subway during rush hour, you'll envy sardines for their big spacious cans.
　　乐乐:哇。地铁站真漂亮!看.有人在演奏萨克斯!多浪漫呀! 　　波比:啊哈!好像音乐是为咱俩演奏的。 　　K K:哦.快打住!我的日票丢了。 　　波比:天!真是你的风格。你比较好再去买一张。不然一旦被抓住逃票你会被罚款250美元. 　　波比:车过来了。希望今天不要太挤。 　　K K:嘿!站到黄线的后面.否则车会撞到你的。 　　乐乐:哦.我没注意我站的地方。 　　波比:要小心!地铁的车门是自动开关的。 　　K K:是啊.挺危险的。上次我被地铁门挤了手，现在还疼呢。 　　乐乐:哦，天哪!有这么多人在地铁里真拥挤啊! 　　K K:在上下班的高峰期你若坐一下地铁，你会羡慕沙丁鱼的罐头有多么大，多么宽敞。
