OG12 70th 过去完成时vs一般现在时

jaze

Excerpt from Manhattan Sc P 109

Note that we do not always  use the Past Perfect for earlier actions. In general, you should
use Past Perfect only to clarify or emphasize a sequence of past events. The earlier event should
somehow have a bearing on the context of the later event. Moreover, if the sequence
is already obvious, we often do not need Past Perfect


放到这里就是 因为冰川以前的存在对那个人提出什么concept是没有关系的，
另外时间顺序已经很明显了，所以就不用过去完成时了。
顺便借你这个帖子问问， 这道题的其它问题， 呵呵， 别介意
原题是这样的
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.
(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 current
temperate areas
(E) when great ice sheets existed in areas now that
are temperate

OG对D是解释是  current should be currently
这个我不明白， 什么意思?
“还有  in current temperature areas is unclear” 这个也不明白， 我觉着很clear啊， 就是现在的温带， 为什么og说unclear呢？
谢谢

个人愚见，欢迎指教~
用current temperate areas ，那么current 是形容词，同temperate一同修饰areas, 那它强调存在于目前的温和的地方，
用currently temperate areas ，此时currently是副词，修饰temperate, 强调目前地温和的地方。
两种表述侧重点不同。

类似的短语还有：seemingly unlimited number,  constantly changing society和seperate, required, courses.
个人感觉，如果是副词修饰形容词的话，二者之间无逗号，如果是两个形容词共同修饰一个名词的话，形容词之间要有逗号间隔。

temperate areas不是温带的意思吗？第一个应该是现在的温带的意思吧？
第二个， 如你所说 如果 currently 修饰temperate
currently temperate areas, 应该是目前温和的地方
可是从正确答案来看， 作者想表达的是  现在的温带的意思
为什么og解释还说要 吧current换成currently呢？
不明白啊
