阅读理解 These days, experiences, like many other things, are becoming increasingly expensive．One has got to pay a lot to get even an ordinary one． Not long ago, I wanted to invite my friend to a lunch．What we really need was a good and quiet place for a talk, not a big meal．So I selected one for people only who belong to a particular club．I belong to the club, too．What could be nicer?“Let's go to the club,”I told my friend． When I ordered a day in advance, I was asked whether I would eat a 20-Yuan lunch．I said, “30 Yuan．”I didn't realize, until I was asked to pay after the lunch, that“30 Yuan”means“30 Yuan for persons each”． There were five people that day, and all of us were surprised by the quality of the 30-Yuan meal(for all, we thought)．The bill came at last：it was 216.40(150 for the five of us plus the money for drinks, fruits and air conditioning)．I paid the bill without a word． What could I say?It was not the club's fault．It was my own ignorance(无知)that made me pay the largest bill in my life． On the whole, it was not so bad．We had a good lunch and at a quiet place．Besides, the experience will help in later years． To support my idea, I have developed my own calculation(算法)：30 Yuan for the lunch and 186.40 for the experience． This paid experience has made me ten times wiser． |
