english question needs to be solved
teIt is not unusual for workers in that region______
A.to be paid more than a month late.
B.to pay later than a month more
C.to be paid later than more a month
D.to pay late more than a month
为什么选A?
为什么不能把WORKERS看做主语选D呢?

答案

你的teIt会不会拼错了,要理解这句话的意思,其实这句话的真正主语确实是workers,前面的只是形式主语罢了.而且如果选D的话,变成了工人自己付工资,工人当然是被付工资啊,所以只能选被动的,只有A合适啦
