Steve wants to travel to London by train instead of bus because

W: Hi, Steve!
M: Hi, Jane. I’m planning to go to London by train. Do you want to come with me?
W: But it would be cheaper by bus.
M: (1) I’ve got a student travel card. You can get cheap train tickets with it.
W: That sounds good. How much does it cost?
M: A card for six months is sixteen pounds.
W: So how do I get one?
M: (3) You need two photographs—one for the card and one for the form.
W: There’s a photo machine in the post office. It gives you four photos for three pounds.
M: So does the one in the library. (2) But I went to a photographer’s studio. It was cheaper.
W: I don’t have to show my passport or my driving license, do I?
M: No, Jane, (3) you only need a letter from your college.
W: OK, I’ll ask my teacher for one.
M: And then you take everything to the tourist office and ask the travel agent.
W: Great, next time you go to London, I’ll come too!
