问题 His studies of ice-polished rocks in his Alpine homeland, far outside the range of present-day glaciers, led Louis Agassiz in 1837 to propose the concept of an age in which great ice sheets had existed in now currently temperate areas.

选项 A、in which great ice sheets had existed in now currently temperate areas
B、in which great ice sheets existed in what are now temperate areas
C、when great ice sheets existed where there were areas now temperate
D、when great ice sheets had existed in currently temperate areas
E、when great ice sheets existed in now that are temperate

答案 B

解析 本题涉及的是what的另一个表达,即:假设原来某地没有名字,而现在叫做A地;那么,如果要表达“原来没有名字的这个地方”,就应该用what,即what is now known as A。这种表达既准确,又简洁。同理,本句应选B。即“原来这块地方的气候特征并不知晓,但现在它是temperate areas”。其余几个选项都无法准确表达此含义。
