问题补充：
The boss insisted that every minute made full use of the work well.
A. be; to do
B. was; doing
C. be ; doing
D. was ; to do
答案：
(答案→)A. be; to do
B. was; doing
C. be ; doing
D. was ; to do
解析：考查虚拟语气和不定式做目的状语：第一空填 be，是因为insisted（坚持要求） 后接that从句，从句谓语要用“should+动词原形”这样的虚拟语气，其中的should也可省略。第二空要填to do，是因为此句谓语为被动语态，假若将此句转换成主动语态，则是 should make full use of every minute to do the work well, 句中涉及 make use of … to do sth (利用……做某事)这一结构。 句意：老板坚持要求每分钟被利用好好工作。选A。
