Mr. and Mrs. Wilson begin their vacation today with their children. And they have to be at the airport (机场) at 11:40 a. m, Yesterday Mr. Wilson said, "It'll take us half an hour to get there in the taxi, so we all have to be ready (准备好的) by eleven o'clock. Nobody should be late.
Now it's ten minutes to eleven. But they are still all running around doing things, except Mrs. Wilson, who is enjoying the sun in the garden.
Her husband and children are very surprised (惊讶的) that she isn't in a hurry. Then the taxi arrives and Mrs. Wilson says to them, "Well, I knew that this was going to happen, so before I went to bed last night I moved all our clocks and watches ahead (提前) twenty minutes. So now we can go to the airport without worrying about (担心) being late."
