A man hired a taxi outside the airfield．The cab had a woolen carpet with brilliant silk edges．On the glass partition(隔板)behind the driver's seat． 1 a wonderful painting．Its windows were all 2 ．The customer was very much 3 and said to the driver, “I've never seen a nicer cab．”“Thank you for your praise, ”the driver answered 4 ．
“How did it occur to you to 5 your ca r?” asked tile customer·
“The car isn't mine．”said the driver．“It belongs to the company．I used to be a 6 of cabs．When they returned, all of them were as 7 as garbage calls with cigarette ends and 8 scattered(散乱)here and there．On the seats or door-handles could be found something 9 like chewing gum．Why so? I thought if the car itself were very clean, the passengers would most likely be 10 ．and avoid littering．”
“When I got a 11 to be a taxi driver, I began to put my idea into 12 to tidy and decorate the car．Now 13．a new passenger get on my car, I would make a 14 and be sure it is in good order．When my car returned after a day's work, it always remains 15 ．”
When doing a thing．one makes efforts and wants to see the 16 ．To change others one has to make twice the 17 but get half the result．To change oneself is tile other way round－more fruit with less effort．One had better ask oneself why one makes 18 on others much more than oneself．If you take enough 19 to do as best as you can for other people's sake, your efforts will naturally 20 ．
