—Grandpa is very busy at present.We'll go to see him whenever __________.

A.he is convenient

B.he will be convenient

C.it is convenient to him

D.it will be convenient to him

答案

答案:C

首先,若用convenient表示“某人方便”之意,绝对不能使用人作主语,而应使用it,由此排除A、B选项,类似地,possible等形容词也不能以人作主语,应使用it作主语。此外,由whenever引导的时间状语从句遵循的是“主将从现”原则,由此判断答案为C
