参考答案：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。

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.
