A.

You are staying with a foreign family who offer you a dish you do not like. Find a way to avoid eating it without offending them.

Oh, is that...? I'd rather not have any, if you don't mind. I'm afraid it doesn't agree with me (The doctor has forbidden me to eat...).

B.

The waiter in a restaurant brings you something you didn't order. Politely point out his mistake.

I'm sorry but I ordered... (Would you mind bringing me that, instead?).

C.

Offer to buy someone a drink in a pub and then order it and something else for yourself.

What are you going to have? (What are you having?) (What would you like?)..., please, and... for me.

D.

A friend of yours is going to have a baby soon. Ask appropriate questions and offer to help in some way.

How is it going? Is everything all right? When are you expecting it? Who is going to look after the children while you're in hospital? Can I do anything to help? I'd be very happy to help in any way...

E.

You are going on holiday tomorrow. Briefly explain to a friend where you are going and what you hope to do.

We're going to... We're planning to... and if we have time (the weather's good), we'll probably... (we'd like to)
