听力原文：W: Hi, Steve!

M: Hi, Jane. I am planning to go to London by train. Do you want to come with me？

W: But it'd be cheaper by bus, isn't it？

M. 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: Not too expensive, actually. A card for six months is sixteen pounds.

W: So how do I get one？

M: 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. 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, 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!

M: Great! We'll have a good journey together.

How much is a six-month travel card？
