With an appropriate conjunctive:

With an appropriate conjunctive:
(1)Though it was late in the night,____ he continued to work vigorously.(2)____ he daydreamed, Peter saw figures in the sky.
【正确答案】：yet; While
【题目解析】：本题考查连接词的用法。【要点透析】在带有让步状语的主从复合句中, though和but不能同时出现,但如果从句中用了 though,主句中可用yet。第二句的两个分句的动作是同时发生的,所以用 while来表示。
