问题补充：

He ill last week and stayed in bed he was well.

A. was; when

B. fell; until

C. was fallen; till

D. had been; before

答案：

A. was; when

(答案→)B. fell; until

C. was fallen; till

D. had been; before

解析：考查固定短语和连词；fall ill病倒；这是一个固定搭配，fall是一个系动词，表示变化。until直到…才…；如果前面句子的谓语动词是短暂性动词，要使用not…until…的形式；句意：上个星期他生病了，一直躺在床上直到他身体好转。故B正确。
