A: Excuse me, sir. I’m trying to find my way to the zoo.
B: Yes. Are you taking a taxi or public transportation? (1)
A: Today I want to go there by bus. (2)
B: That’s good. First of all, you are on the wrong street. You have to walk more than two blocks to Roosevelt Road where you’ll catch Bus No. 236. Get off at the terminal.
A: Thanks a lot.
B: Not at all.
1.“Are you taking a taxi or public transportation?”不是询问对方正在进行的情况，而是询问对方将作何打算。
2.“by bus”是“坐公共汽车前往……”，其它交通工具，基本上也都与介词by搭配，例如：by air 乘飞机
by train 乘火车
by underground 乘地铁
by electric car 乘电车
但如果是走路的话，则应该用“on foot”，而不是“by foot ”。
Larry: Excuse me. I’m trying to find the museum. How do I get there?
Justin: Go straight down Fifth to Washington Park. Turn right at the bank.
Justin: No, no! Wait! Don’t do that! I just remembered. That’s a one-way street (1). You can’t turn right there.
Larry: Excuse me?
Justin: OK, first, go straight down Fifth to 23rd Street, where Broadway crosses Fifth (2). Then go one block to the traffic light (3). Don’t take the first right. Take the second left (4), onto Broadway.
Larry: I’m sorry, I don’t understand.
Justin: Here’s Fifth Street. Here’s Broadway. The museum is at Prince and Broadway. (5)
