完形填空

　　“Where are you going?”This question 　　1　　 by Chinese when two friends meet in the street．But if you ask Americans 　　2　　 question, they will be puzzled because they think 　　3　　“going to some place”is quite a private business 　　4　　 their own．It has 　　5　　 to do with other people．In their eyes, only a policeman will ask such a question in the street．

　　The same thing will happen 　　6　　 Americans if you ask,“Have you had your meal?”In fact, to us Chinese, such questions do not mean anything 　　7　　 a greeting．In America two friends meet in the street, they 　　8　　 say,“Hello!”or“How are you?”They 　　9　　 ask,“Where are you going?”or“Have you had your meal?”If two friends meet 　　10　　 and one asks the other,“Have you had your meal?”That 　　11　　 he wants to invite his friend 　　12　　 a meal with him．It's quite different from what it means in Chinese．

　　The examples 　　13　　 tell us that people in different countries 　　14　　different custom．Now we are learning foreign languages, we must pay great attention to(注意)　　15　　 customs．
