【正确答案】当今的世界比历史上任何一个时期都要不平等。这有其基本原因：200年前，每个人都很穷。经济发展只是相当近来的一段时期(发生)的事，但这却是经济状况出现极大分化的时期。世界上相对很小的一部分地区达到了经济学家称为现代经济发展/增长水平，而且他们在人均收入方面，年年持续增长。如果你将两个世纪以来的增长累计，那将是个相当大的变化，从物质条件来衡量，(生活水平的)增长也许是20倍或更多。

【答案解析】[听力原文]
The world is more unequal than at any time in world history. There's a basic reason for that: 200 years ago everybody was poor. The period of economic growth is a fairly recent period, but it's been a period of extreme differentiation in economic performance. A relatively small part of the world achieved what the economists call a modern economic growth. And they sustained the increase year after year, in income per person. When you accumulate that over two centuries, you get quite a change, maybe a twenty-fold increase or more in the standard of living measured in material terms.

【正确答案】如图所示，世界各国每10万居民拥有的医生数有很大差异。令人惊奇的是意大利的这一数字比英国高得多。这却又是事实。意大利的这一数字是400左右，而英国每10万居民拥有的医生仅略多于160人。西班牙和比利时的数字也远高于英国——西班牙为略高于350人，比利时约为310人。

【答案解析】[听力原文]
There is a great range in the number of doctors per 100,000 inhabitants in various parts of the world, as we can see from the chart. It is surprising that the figure for Italy should be a great deal higher than for the United Kingdom, but that is the case. In Italy the figure is around 400, while in the United Kingdom, it is only a little over 160 doctors per 100,000 inhabitants. Both Spain and Belgium have considerably higher figures than the United Kingdom - slightly over 350 in Spain and about 310 in Belgium.
