问题补充：
——Do you think it necessary that he to Miami but to New York?
——I agree， but the problem is he has refused to.
A. will not be sent; that
B. not be sent; that
C. should not be sent;what
D. should not send; what
答案：
A. will not be sent; that
(答案→)B. not be sent; that
C. should not be sent;what
D. should not send; what
解析：:该题的考点之一是it necessary (strange，natural，important)that…结构中的that从句要求使用虚拟语气，体现形式是谓语动词用should+动词原形，should也可以省略。由此我们排除A项;考点之二是he has refused to这个表语从句的引导词不能用what，因为从句成分健全，不需要what在从句中充当什么成分。故答案为B。
