问题补充：

I to the lecture that afternoon, but I a bit ill.

A. should have gone; was

B. would have gone; had been

C. should go; was

D. would go; had been

答案：

(答案→)A. should have gone; was

B. would have gone; had been

C. should go; was

D. would go; had been

解析：考查虚拟语气。根据时间状语that afternoon可知是对过去的情况比赛虚拟，使用情态动词+have done,排除CD。Should have done本应该做某事，实际上却未坐；would have done会做某事。But后面的句子应该使用陈述语序，根据前句的that night可知后半句使用过去时。故A正确。
