Question

大神，句子里的which和that分别指代什么呢？His Reward Group is exploring a slew of tie-ups with French firms which, despite their suspicions, come as welcome news for a government that has prioritised kick-starting the economy.
句中的which和that分别指代那些词呢?

Answer 1

where相当于in which place.
比如这两个句子：
1) i don't know where she put it. 我不知道她把它放哪儿了。
相当于这个句子
2) i don't know in which place she put it.

如果把in which place的in 和place 去掉，which就变成了赤裸裸的充当定语从句的定语了，用于引导一些有“哪”，“哪个”提问的定语从句，比如i don't know which one she likes best. 我不知道她最喜欢哪一个。
而where应该是状语从句，不是定语从句。
i don't know where to go, 我不知道去哪儿。i don't know where should i put it. 我不知道我该把它放在哪儿。“哪儿”表示“在。。。地方”，是状语，因为有个“在”的介词在前面。
