I think it that she should be knowledgeable about computers for her present job.

A. urgent

B. normal

C. gifted

D. essential

答案：

A. urgent

B. normal

C. gifted

(答案→)D. essential

解析：考查形容词辨析。urgent紧急的，normal正常的，gifted有才能的，essential必不可少的，题中用it作形式宾语，真正的宾语是后面的从句。句意：我认为对于她目前的这份工作，她应该掌握更多的电脑知识是必不可少的。故选D。
