问题补充：
Our teacher found her and gave her some different homework to do every day.
A. was clever
B. was a clever girl
C. clever girl
D. a clever girl
答案：
A. was clever
B. was a clever girl
C. clever girl
(答案→)D. a clever girl
解析：句意：我们的老师发现她是一个聪明的女孩，每天给她一些不同的作业做。find (that) +从句，发现.....。如果是AB项，应为：Our teacher found she was clever/was a clever girl。而find sb （to be）+a +adj+n,表示发现某人怎么样，故选D.
