помогите пожалуйста перевести в косвенную речь)))))
t’s eleven o’clock in the morning. Helen Petrova’s in one of the biggest department stores in the city which only opened a few weeks ago. Many things are bought and sold here every day. Though it’s still early and the store has just opened, there are a lot of customers near the counters: some are buying things, others are just looking round.
Helen: Excuse me. How do I get to the shoe department? Shop assistant: It’s over there on the lett, please.
(In the shoe department)
Helen: I want a pair of boots please.
Shop assistant: What’s your size?
Helen: Thirty-four, and I want very warm ones, too. It's very cold outside.
Shop assistant: Oh yes, it’s terribly cold. Thirty-four... You have very small feet. It won’t be easy to find a suitable pair, I’m afraid.
(In a few minutes)
These are nice boots, don’t you think? Will you try them on? How do they feel?
Helen: I think they’re a size too big. Perhaps you can find a.different pair. Can you give me a size smaller?
Shop assistant: Just a moment. I’ll have another look. You’re lucky. Here’s a lovely pair; but it’s more expen sive.Helen: That doesn’t matter... It feels more comfortable. I think I’ll take it. How much is it?
Shop assistant: Seventy-five roubles.
Helen: Where do I pay?
Shop assistant: Over there at the cash-desk.
Helen: Thank you.
(After paying the bill)
Shop assistant: Here are your boots. The check’s inside.
Helen: Thank you. And where’s the glove department?
Another customer: Come along with me, and I’ll show you.
Helen buys some dark-brown gloves to match her new boots and looks at her watch. She sees that it is rather late, so she quickly leaves the store and hurries home.-
