　　The measure of a man's real character is what he would do if he knew he would never be found out．

——Thomas Macaulay

　　Some thirty years ago,I was studying in a public school in New York．One day,Mrs Nanett O'Neil gave an arithmetic 　　1　　 to our class．When the papers were 　　2　　 she discovered that twelve boys had made exactly the 　　3　　 mistakes throughout the test．

　　There is nothing really new about 　　4　　 in exams．Perhaps that was why Mrs O'Neil 　　5　　 even say a word about it．She only asked the twelve boys to 　　6　　 after class．I was one of the twelve．

　　Mrs O'Neil asked 　　7　　 questions,and she didn't 　　8 　　us either．Instead,she wrote on the blackboard the 　　9　　 words by Thomas Macauly．She then ordered us to 　　10　　 these words into our exercise— books one hundred times．

　　I don't 　　11　　 about the other eleven boys．Speaking for 　　12　　 I can say：it was the most important single 　　13　　 of my life．Thirty years after being 　　14　　 to Macaulay's words,they 　　15　　 seem to me the best yardstick（准绳）,because they give us a 　　16　　 to measure ourselves rather than others．　　17　　 of us are asked to make 　　18　　 decisions about nations going to war or armies going to battle．But all of us are called 　　19　　 daily to make a great many personal decisions．　　20　　 the wallet,found in the street,be put into a pocket 　　21　　 turned over to the policeman?Should the 　　22　　 change received at the store be forgotten or 　　23　　?Nobody will know except 　　24　　．But you have to live with yourself,and it is always 　　25　　 to live with someone you respect．
