THE EXCUSES

The office was silent. «So, let me get this right», (1) ... Alison calmly. «Not one of you is willing to donate some money towards Mr. Bartlett‟s leaving present». There was silence again for a moment, then Deidre (2) ... up, saying that she (3)... love to give a donation, but unfortunately her house (4) ... being painted that week and she (5) ... not have any spare cash at all. Alec was next. He was very apologetic and said that he (6) ... meant to bring some money to work (7) ...

morning, but had forgotten. Perhaps tomorrow? Bette said she (8) … not give anything until she (9) ... her pay cheque at the end of the week. Alison stared at them all. She (10) ... them how disappointed she (11) … with all of them, and that she (12) ... remember their excuses when it was time for (13) ... to retire. She slammed the door behind her as she left the room.

Read the text and complete the sentences using the third conditional.

Some scientists, such as Stephen Hawking, believe it‟s possible that there are billions and billions of universes. Each universe has a different possible consequence for every action. In the universe we live in, for example, George Bush became President of the USA in January 2001, and Greece won the European Cup in July 2004. But in other universes different things happened. Imagine if that‟s true! In some universes, your parents didn‟t meet, so you weren‟t born. In another universe, a meteor didn‟t strike the Earth, so the dinosaurs didn‟t become extinct. In a different universe, your best friend won the lottery last summer and moved to a bigger house. In another parallel universe, you started learning English a year earlier, so you did this book last year! Somewhere else,

Madonna wasn‟t discovered, and so didn‟t make any records. In another universe, Van Gogh was recognised as a great painter during his lifetime, and so didn‟t die in poverty. And perhaps in several universes, there were enough lifeboats on the Titanic and so everyone on board survived. It makes you think, doesn‟t it?
