og 11 上的第五题

As its sales of computer products have surpassed those of measuring instruments, the company has become increasingly willing to compete for the mass market sales they would in the past have conceded to rivals.

A. they would in the past have conceded to rivals

B. they would have conceded previously to their rivals

C. that in the past would have been conceded previously to rivals

D. it previously would have conceded to rivals in the past

E. it would in the past have conceded to rivals

答案选的是E，但是如果是E的话，主语it 的谓语不是应该是has conceded 么？这个 Have conceded 。。。。哪位大侠给解释解释吧。。。。SO 混乱呀。。。。。这话到底该怎么分析啊？

in the past你可以看成插入语嘛！

其实是would have conceded

it指代company(突然想起prison break...)

。。。。。哪为啥不用would has conceded。。。。

。。。would后面只能跟动词原形啊。。。

但是白勇的书上说这个would have done 是跟在if 从句里面才用的。。。。。
