问题补充：

The teacher has confidence in the naughty but clever boy and is sure that he to a key university．

A. would be admitted

B. was admitted

C. has admitted

D. will be admitted

答案：

A. would be admitted

B. was admitted

C. has admitted

(答案→)D. will be admitted

解析：句意：老师对这个调皮但是聪明的男孩很自信，并确信他将被重点大学录取。从主句：is sure可知宾语从句的时态不是过去范畴的，排除AB，还有the boy和admit是被动关系，所以C不对，选D。
