Without animals and the information the animals gave,it (would have taken) man much longer to go

问题描述:

Without animals and the information the animals gave,it (would have taken) man much longer to go
space.would have taken thanks

没有动物及动物给予的信息,(这个)人将要花费更长的时间(或者路)来走出去.这里go的情景要你自己看着办翻译了.
将要花费更多的时间:will take ,根据前面一句的gave,所以应该是 would have taken
