单选题If you intend using humour in your talk to make people smile, you must know how to 27 shared experiences and problems. Your humour must be 28 to the audience and should help to show them that you are one of them or that you understand their situation and are in 29 with their point of view. Depending on whom you are addressing, the problems will be different. If you are talking to a group of managers, you may refer to the 30 methods of their secretaries; 31 if you are addressing secretaries, you may want to comment on their disorganized bosses. Here is an example, which I heard at a nurses' convention, of a story which works well because the audience all shared the same view of doctors. A man arrives in heaven and is being shown around by St. Peter. He sees wonderful 32 , beautiful gardens, sunny weather, and so on. Everyone is very peaceful, polite and friendly until, waiting in a 33 for lunch, the new arrival is suddenly pushed aside by a man in a white coat, who rushes to the 34 of the line, grabs his food and stomps over to a table by himself. 'Who is that?' the new arrival asked St. Peter. 'Oh, that's God.' came the reply, 'but sometimes he thinks he's a doctor.' Look for the humour. It often comes from the unexpected. A twist on a familiar 35 'If at first you don't succeed, give up' or a play on words or on a situation. Search for 36 and understatements. Look at your talk and pick out a few words or sentences which you can turn about and inject with humour. A. accommodations B. identify C. notorious D. disorganized E. quote F. canteen G. attempt H. alternatively I. sympathy J. line K. exaggerations L. increasingly M. head N. end O. relevant
