A man hired a taxi outside the airfield.The cab had a woolen carpet with  36 lace edges.On the glass partition that  37 the driver's seat was a copy of a famous painting.Its windows were all clean.The customer was very much  38 and said to the driver,“I've never seen a nicer  39 .”“Thank you for your praise.”the driver answered  40 
“The car isn't mine,”said the driver.“It belongs to the company.I used to be a  41 of cabs.When they returned,all of them were as  42 as garbage cans with cigarette butts and rubbish  43 here and there.On the seats and door-handles could be found something  44  like peanut sauce or, chewing gum.Why so? I thought if the car itself were very clean the passengers would most  45 be considerate and refrain from littering.”
“So when I got a  46 to be a taxi-driver,I began  47 my idea into practice-to tidy and  48 the car. Now before a new passenger gets on my car,I'd make a cheek and be sure it is in good order.When my car  49 after a day's work,it always remains  50 .”
When doing a thing,one makes efforts and wants to see the result.To change others,one has to make twice the  51 but get half the result.To change oneself is the other way round-more fruit with less effort.One had better ask oneself why one makes  52 on others much more than on oneself.  53 you take enough care to do as best you can for other people's sake,your efforts will yield results,If you  54 the inner world of your own,examine yourself and wipe out the dust and dirt,instead of fixing your eyes on other people,you will find a cheerful  55 for yourself and create a pleasant environment for others.
