问题: 英语选择题

what do you think ____ left in his classroom?
A.he was B.he's
C.him D.he is
为什么选B,不选A.还有B,D不是一样吗???


____ the boy said turned out to be true.
A.Which B.All that
C.What D.Where
为什么选C,不选B,在什么情况下可用B??

解答:

因为he's left中's的缩写是has,是主动语态。
What the boy said是主语从句。B也是对的,all 作主语,that the boy said是顶语从句。但我估计是你抄错了。B.应该是all what这样就不对了。
