过去时态的

The events described by the aorist tense are classified into a number of categories by grammarians.

第一简单过去式和第二简单过去式，在时间上没有分别，不过是用两种不同的形态，造成动词的同一时态。

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.

我记得很多老师讲过去完成式的时候说这个时态用在一个过去的事情发生在另一个过去的事情以前的时候用，按照此理容易选A 因为

59B 59B iceoutside His studies of ice-polished rocks in his Alpine homeland, far outside the range of presentpresent-day glaciers, led Louis Agassiz in 1837 to propose the concept of an age in whick great ice sheets had existed in now currently temperate areas.

an age + in which / when 时态问题：发生在过去的动作要用一般过去式，不能用过去完成时 now 和 currently 语意重复副词的位置：now 放在系动词，助动词的后面，普通动词的前面，以及动词短语的中间。

时态在翻译中比不像想象中那么简单，往往是考试中的一个难点。时态有时可以体现一种感情因素，特别是进行时的使用，比如在第一个例子中现在进行时的使用体现出对中华民族的一种褒扬、赞美的口吻，翻译出了这句话的&精、气、神&，最后一个例子中过去进行时时常表示一种&特有的行为&，通常是偏向于negative的口吻，所以我们发现这句话十有八九是美国人自己写的。
