Susan sat down switched on her computer and was just about to read her overnight emails when the door flew open. "Valerie! What are you doing here? You are A1 ____ to be on holiday in Italy!"
Susan was astonished. She and Val worked together as receptionists at the hospital. Because she had expected to be on her own and working twice as hard, she was quite pleased to see Val. On the other hand she knew that Val was really looking A2 _______ to her holiday. What could possibly have gone wrong? Val walked in but she didn't say a A3 ______ word. It was clear that she was upset and tired. "What is it? What's happened?" Susan continued. "Is everything OK?" Valerie was silent for some moments but eventually A4 ______ . "You clearly haven't heard the news. Our travel company went bankrupt on Friday. We didn't know and so went to the airport on Saturday morning. Actually we have spent the whole weekend at the airport hoping still to get a flight. In the end we gave A5 ______ and came home". "Oh you poor thing," Susan gushed. "Let me make you a cup of tea but then you should go home. You still have two weeks holiday to A6 ______ . Why don't you go somewhere in England?
The weather is certainly nice enough at the moment." "Well," replied Val, "it seems that we will be OK to go to Italy still. We had travel insurance and it seems we will get all our money A7 _____ . So we'll try again in the autumn with a different travel company."
