听力原文: Different cultures have considerably differing habits in the amount of expressiveness. This is rooted in the varying attitudes toward people of different ages, classes, and stations in life. In the family setting, for instance, most Americans encourage their children to enter freely into dinner table conversation and other family discussions and to participate early in decision making. By contrast, in Asia and elsewhere, children are taught to be silent in the presence of elders and, for instance, are usually separated from them when eating. The children certainly are never to disagree verbally with the parent, or with older brothers and sisters, for that matter. In parts of India, even an adult would not enter into the decision-making discussions if his aged parents were still in the family circle. It is not surprising, therefore, that many foreigners look upon American young people as brash, immodest, and rude, possessing no proper respect for parents or older siblings. On the other hand, Americans may look upon young people of other cultures as being too reticent, too quiet, too unresponsive, too lacking in self-confidence, which may be interpreted erroneously as inferiority. In many countries a student would very seldom ask a question in class, for to do so would not only suggest that he is uninformed but that he is implying that the teacher has been unclear, which would be highly disrespectful. In America most teachers encourage the student to ask all kinds of questions. It is a mark of good teacher to draw out questions and a mark of a good student to ask numerous, meaningful questions. American teachers abroad thus have to realize the lack of questions or lack of recitation from their students does not mean that the teacher is being ineffective and the students are ignorant and lethargic, for they are merely being respectful.Which continent where children are taught to be silent in front of elders is mentioned?A.Europe.B.North American.C.Asia.D.South American.
A.B.WhichC.Europe.B.NorthD.C.Asia.D.SouthE.
