Question

一道英语题（定语从句）

In an hour, we can travel to places __which__ would have taken our ancestors days to reach.
这里的which除了在从句中作主语，是不是还是reach的宾语？是一种倒动宾关系吗？
如果把reach改成arrive（不及物），这时还能填which吗？能不能填which是看在从句中做的成分还是和从句最后的那个动词是否形成动宾关系？

Answer 1

说实话，我觉得你的这句话似乎不太正确。In an hour, we can travel to (应该有the) places __which_（应该有个it) would have taken our ancestors days to reach.
定语从句还原成为句子应该是：It would take our ancestors to reach the places.
所以，本句应该是：
In an hour, we can travel to （the）places __which_（it)_ would have taken our ancestors days to reach.
如果改为arrive，则引导词可改为where，或在arrive后加at.

Answer 2

which是作定语从句的主语，同时又是reach逻辑上的宾语
就像I have a lot of work to do 。中这个结构一样，do也是及物动词

Answer 3

其实从句的句式应该是这样的 to reach the places would have taken our ancestors days. 如果改为arrive的话，应该填的是at which. arrive in 加大地方，arrive at 加小地方。

Answer 4

填which，引导定语从句，先行词是town，which在从句中做主语
