Cambridge is one of the most important and beautiful towns not only in Britain, but also in Europe. The quality of its buildings, in particular those belonging to the University and the particular atmosphere with river and gardens have given the city a place of the itinerary of every visitor to this country. The University has influenced not only the architecture of the town, but also its character: its bookshops are among the finest in the country. The frequency of the dramas and concerts and the wide range of restaurants reflect the tastes and interests of the academic population. As the visitor will undoubtedly begin his tour in the University buildings, let"s describe those first.

【答案解析】那些真正成功的例子，那些我们现在称为发达经济体的国家，都是高收入经济体，或者，工业化经济体。那些国家只代表了约1/6的人类。剩下5/6的人类被我们称为发展中世界。这是世界的大多数。有些情况下两者之间的差距可达100比1，如果你简单地将美国的人均国民生产总值与比如说非洲某国相比，也许就是人均3万美元对人均300美元。这绝对令人震惊，在同一星球上竟然有那么极端的物质福利的差异。 [听力原文]
It happens that the real success stories, those countries that we now call the developed economies, were the high income economies or, the industrialized economies. Those countries represent only about one-sixth of humanity. And five-sixths of humanity is what we call the developing world. It"s the vast majority of world. The gap can be 100 to one in some cases if you simply measure the gross national product per person in the United States versus, say, a country in Africa, maybe a gap of $30,000 per person and $300 per person. That"s absolutely astounding, to be on the same planet and to have that extreme variation in material well being.
