Dialogue 1. A Visit to London

A: What do you think I ought to see in London first?

B: Well, historical places, I think. You should go to Westminster Abbey, and if you can, go to the Houses of Parliament and the National Gallery.

A: And what about the British Museum? I was told one ought to see it.

B: I suppose you must go there. There you can find masterpieces of the world’s best artists.

A: How can I get to the centre?

B: I think you can go by steamer down the Thames from Westminster to Tower Bridge. That’s a very pleasant way to travel, and you can see London bridges and quite a number of buildings on the way.


Dialogues 2. Asking the Way

A: Excuse me. Can you tell me where South Street is, please?
B: Take the second turning on the left and then ask again.
A: Is it far?
B: No, you can walk it under ten minutes.
A: Thanks very much.
B: It’s a pleasure.

Dialogues 3. Shopping

A: Let’s go shopping. I have got quite a number of things to buy, and I believe I can get them all in this shop. You see, I ought to buy a present for my friend. She has invited me to her birthday. What shall we look at first?

B: Gloves, I think. They must be on the ground floor. Yes, here we are, and I can see just the kind I want.

A: Well, that didn’t take us long, now let’s go up by the escalator to the third floor.

B: We’ll just take a quick look around to see if there is anything we could take back as presents for the family.

A: I like these books, and do you? Shall we ask how much they are?

B: I want to get a comb and some hair clips. Where do you think I can find them?

A: Oh, you must go to the haberdashery department. That’s on a lower floor, I believe. We’ll get them on our way out.

B: How do you like those white shoes just over there, on the right?

A: I like them very much, indeed. They are perfect for summer wear.

B: Do you think they’re my size? They look just about right.

A: You should try them on.
