问题补充：

Boris has brains.In fact, I doubt whether anyone in the class has IQ.

A. a high

B. a higher

C. the higher

D. the highest

答案：

A. a high

(答案→)B. a higher

C. the higher

D. the highest

解析：考察形容词用法。形容词的比较级和否定词连用表示最高级的含义。has brains有头脑;有智慧.anyone in the class与Boris相比较,要用比较级.当比较级后有名词时,要加冠词.the higher IQ(两人中)比较高的智商,不能作为答案.句意：Boris很有头脑。我怀疑在班级里是否有谁比他的更高的智商。故B正确。
