引导状语
It's unclear with the short time between setting up committees and negotiating staff arrangements in the narrowly split chamber what that would mean for how quickly confirmation hearings and floor votes can happen with just two weeks before the inauguration.
这个it形式主语,what that would mean主语从句,那么这个for是如何理解呢?
for就是“对于”的意思
如It means a lot for me and my family.
如果你的句子不是it's unclear...what这个结构,或者说假设我们已知what would that mean?的内容,那么可以改为
That would mean 'something' for the speed at which 'confirmation hearings' and 'floor votes' can happen with just two weeks before the inauguration.
