选择题
_____ to make a speech, he said he would be glad to.
A.When asked
B.When asking
C.When he was asking
D.When to ask
答案
答案:A
题目分析:考查状语从句的省略,在含有状语从句的复合句中,若从句的主句是it或与主句的主语相同,且在谓语中含有be时,常省略从句的主语和be。句子意思:当他被要求做演讲时,他说他会很乐意的。完整的句子是When he was asked to make a speech, he said he would be glad to.主从句的主语都是he,可以省略从句的主语和be动词,剩下asked,选A。
