It was Friday evening. Liz was looking forward to Saturday because it was her husband’s birthday.
She had been preparing for this event for a long time. She had invited __________________(THEY) college friends and they were all coming from different cities. The best part was that Carlos, her husband, __________________(NOT/KNOW) anything about the arrangements. It was going to be a surprise. Liz __________________(MAKE) sandwiches when Carlos came into the kitchen. “Look, darling,” he said, “I know it’s my birthday tomorrow but I don’t want to do anything special for it.” Liz thought, “I wish I __________________(CAN) cancel the party but I can’t – it’s too late. The party will take place anyway and it will be the __________________(GOOD) party ever”. When Carlos came home on Saturday, there __________________(BE) lots of people there. Carlos __________________(TELL) them that he felt very happy to see them all and it was true! The guests enjoyed their dinner and then Liz brought in a cake. The cake __________________(DECORATE) with chocolates and jellies, and it had as many candles as the number of years Carlos had reached them.

I'm absolutely sure that people's opinion of British food is based on ignorance. They say we eat potatoes with everything. But you __________________ (RARE) get a meal anywhere in Europe that does not come with chips. The __________________ (DIFFER) is that we do not boast about our cuisine. In my view, we are very __________________ (CREATE) when it comes to food. In Britain, you can enjoy a wonderful __________________ (COMBINE) of dishes from different cuisines. You can wake up in the morning and have an English breakfast, a slice of Italian pizza at lunchtime, Japanese sushi for dinner and a Turkish kebab on the way home from the club. What else could you ask for? And never tell me British food is __________________ (TASTE) and boring! That's just __________________, (FAIR) so come and try it for yourselves.
