答案选E吧? A太啰嗦了,in addition to how, when 什么的,没这说法啊,干掉 B形势就觉得不怎么爽,干掉 对比CDE,感觉to determine和for determining差不多,先放着,后面是说提供线索用来知道when和how mammals colonized the islands of the West Indies 的,感觉WHEN和HOW的关系是并列,且DE中后面出现了when they did和how they were,还要让人想they指代什么,所以E的答案更清晰,语意上也比较流畅
2.Picky:C选项中的when "they" did指代谁呢?照理来説指代平行中一样位置的N 所以可以找到是指代mammals,但是,你看到他用了when they "did"既然连动词都省略了,他的指代词同理不也应该省吗?省完之后会发现 to determine how......and "when" 就把关代绑在一起吧,你就会看到结果是E的选项,然后改掉to 变 for
