Complete the conversation between Nick and Mai about British table manners with the sentences given (A-J). Practice the conversation with your partners. A. If you are a guest, it is polite to wait until your host starts eating or indicates you should do so. It shows consideration. B. When you have finished eating, and to let others know that you have, place your knife and fork together, with the prongs on the fork facing upwards, on your plate. C. Yeah, of course, Mai. First, we are expected to eat properly with cutlery, especially fork and knife. D. Right. Hold your knife with the handle in your palm and your fork in the other hand with the prongs pointing downwards. E. You may eat chicken and pizza with your fingers if you are at a barbecue; otherwise, always use a knife and fork. F. If you have a knife in one hand, it is wrong to have a fork in the other with the prongs pointed up. G. Yes, they are sandwiches, crisps, and fruit. H. Well, the fork is held in the left hand and the knife in the right. I. Always say thank you when you arc served something at a party. And in a restaurant, it is normal to pay for your food by putting your money on the plate which the bill comes. J. Of course not. Rest the fork and knife on the plate between mouthfuls, or for a break for conversation. Mai: Can you tell me a little bit about English table manners, Nick? Nick: (1) ____________________________________________________________ Mai: How can we use the fork and the knife in the correct way? Nick: (2) ____________________________________________________________ Mai: l see. But is there anything that we should not do? Nick: (3) ____________________________________________________________ Mai: Our teacher has already mentioned it in the English lesson. Nick: (4) ____________________________________________________________ Mai: Do we hold the knife and the fork all the time? Nick: (5) ____________________________________________________________ Mai: Are there any foods that you don't eat with a knife, fork or spoon? Nick: (6) ____________________________________________________________ Mai: And is there any that we eat with our fingers, Nick? Nick: (7) ____________________________________________________________ Mai: If we are invited to a party, when should we start eating? Nick: (8) ____________________________________________________________ Mai: How can we show that we finish eating? Nick: (9) ____________________________________________________________ Mai: Anything else? For example, say “thank you” or pay the bill? Nick: (10) ____________________________________________________________ Mai: Thank you so much. I think all of us should have good table manners at anywhere, in England or in Viet Nam. Nick: You're welcome, Mai. Mong mọi ng giúp
