C. discussed; was
D. should discuss; should be
答案：
(答案→)A. discuss; was
B. would discuss; should be
C. discussed; was
D. should discuss; should be
解析：考查suggest用法。当suggest表示建议的时候，后面的宾语从句使用“should+动词原形”构成的虚拟语气，Should可以省略。当suggest表示说明，暗示的时候，使用陈述语气。句意：他建议我们晚些时候再讨论这个计划，这一点说明他反对这计划。说明第一空使用虚拟语气，第二空使用陈述语气。故A正确。
