标题: in which & when的疑问~
以前上XDF的时老师讲说 age用in which 修饰； time 具体年代用when修饰

但是今天看到OG12里的一道题目 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 existed in what are now temperate areas.（正确的句子）

OG里面解释说In which or when can be used interchangeably in this sentence.

想知道为什么？那以后看句子是不是不能根据in which 和when直接排除了？？

【PERIOD OF HISTORY】 [C usually singular]
a particular period of history
　

We are living in the age of technology.

朗文字典关于Age解释有这么一个。in the age，所以这道题可以用in which。OG也说了这个句子里他们是可以互换的

又查了一下，确切的讲，这道题里还是应该只用in which。

age后面可以跟in which 和when，不过这道题里的age应该是in的意思。

age前面可以跟in/at/of几个介词。

【HOW OLD】 [U and C]
the number of years someone has lived or something has existed
　　

Dad retired at the age of 56.

at age 5/18 etc
　

In Britain, schooling starts at age 5.
4/15 etc years of age
(=4, 15 etc years old)
　

She was just over 16 years of age.

加上上面的in。

when可以=on which和at which，=in which还是少。

used after an expression of time to mean 'at which' or 'on which': Sunday is the only day when I can relax. ◆ There are times when I wonder why I do this job.

at which time; on which occasion: The last time I went to Scotland was in May, when the weather was beautiful.

所以这道题还需要讨论。

About "when" vs. "in which", an earlier comment demonstrated the correct usage:

I was 18 when...
It occured during an age in which...

Specific age should be "when", referring to a period of time should be "in which".

基本上我算弄明白了，lz还不明白，就google一下吧

我不是NN，只是说一下自己的看法。
过去完成时是绝对不能和 now 同时出现的~

对，in which 和when地位是平等的，但是比where好，所以不能根据这个排除in which

根据Ron的答复。Peggy说的是对的。刚刚看懂D选项的 existed in current temperate areas 是说 ice sheet 存在于当前的温带。跟B答案有本质的区别。 B答案是说：存在于当前是温带的区域（隐藏含义，之前不是）。而E ares Now that are temperate 一个是now的位置不对，体会于 areas that are now temperate的区别

哦d确实不对。我想问一下B的what are now temperate areas，怎么感觉好奇怪？

我也想问这边为什么不能用过去完成时

只是个定语从句罢了

我觉得是因为不用had done 也可以知道事情发生在led to propose 这个动作之前
所以不需要额外用had done来表示动作发生的顺序了

Ron:the emphasis of the sentence is on the fact that the ice sheets ACTUALLY EXISTED during this time. the sentence is not meant to emphasize the persistence of the ice sheets before that age, nor is it meant to suggest that the existence of the ice sheets was a completed action. therefore, the regular past tense is better.
