| 阅读下面短文，掌握其大意，从每题所给的A 、B 、C 、D 四个选项中，选出最佳选项。 One day, I heard an American boy say to a Chinese girl student, "You speak very good English."But the girl answered, " No, no. My English is very poor." The foreigner was quite 1 at the answer. Thinking he had not made 2 understood or the girl had not 3 him clearly, he said , " Yes , indeed, you speak very well." 4 the girl still kept saying , " No." In the end the American boy could not understand and didn’t know 5 to say. What’s wrong with the girl’s answer? She didn’t 6 a compliment (恭维)in the same way as the American people do . She should answer , " Thank you” instead of " No" . She 7 understood what the American boy had said, but she thought she should be modest. In the 8 , people will feel proud and 9 when they are praised . So if someone says the 10 you have cooked are very delicious , you should say , " Thank you ." In our country we think being modest is a virtue ( 美德) and being proud is a bad thing , but in my opinion , being confident does not 11 being proud , so sometimes you should be confident 12 being modest. 13 you are modest and say , "No , I'm afraid I can’t do it well" , while working in a western country, the others may think that you really cannot do it . If you often say "No" , you will certainly be looked down upon by 14 . When asking for a job , if one says something like "Yes , I can certainly do it " instead of " Let me have a try ” , he or she will 15 get it . So in the west , you should be brave to show your self-confidence. | |||
