【听力原文】
　　Is the United States a melting pot? In other words, have immigrants to the USA merged with the Native Americans and ceased to be Germans, Poles, Irish, etc.? It has been suggested that [24] a “pot of stew” might be a more suitable word than “melting pot”, for in a stew the meat and vegetables keep their own characteristics, a distinctive flavor of its own.
　　[24] The implications of “melting pot” disturb American social workers and language teachers, many of whom feel that racial and national groups should be encouraged to preserve their customs, traditions and languages. At the same time it is agreed that all Americans, whatever their origins, must learn to speak English clearly and fluently, and that they must learn to adapt themselves to the American way of life.
　　However, there are ethnic groups who still stick together, who speak their own languages and have preserved many of their old customs. [24] There are Hispanic communities, most of whom still speak Spanish as their first language. There are American Indians and various Asian groups, all of whom speak their own languages. [24] Many descendants of European Immigrants have also stayed together in groups. With the exception of the Anglo Saxons, the Germans are the largest ethnic group in the US
　　A. They have made a considerable contribution to their adopted land and have helped to enrich a distinctive American English language. [25] The commanders-in-chief in both world wars were of German ancestry. [26] Many blacks are too bitter against white culture to feel American. They are beginning to trace their roots back to the African tribes from which their ancestors were torn in the days of slavery, and some of them are identifying themselves more and more with Africa.
