问题描述:

On the floor_the box they had been looking for
A.were lying
B.lay
C,laid
D.lying
选B.为什么不选D?
from the top of the hill_the whole city
A.where could be seen
B.could be seen
C.from which coule see
D.could see
为什么选B,不选A或者D?

两个都是倒装语法点
属于方位副词位于句首的倒装,你把他们还原成正常语序就是:
the box they had been looking for (lay) on the floor.
显然是过去式,如果选D,没有动词了,得加was
第二个还原成正常语序:
the wholl city could be seen from the top of the hill
不久很清晰吗?的定语从句的思路,也不会按照D 的主动去判断了
