Question

两道英语的Verb-filling
The reportershurried to the airport,only (tell)the film stars had left.
Unless (invite) to speak,you should remain silent at the conference

Answer 1

1 to be told
only 与动词不定式连用 表示意料之外的结果 又因为题中reporter是被告知 因此用动词不定式的被动语态
2 invited
英语中,在由when/while引起的时间状语从句,if/unless引起的条件状语从句,though/although引起的让步状语从句中,如果从句的主语与主句主语相一致或从句主语是it,而从句中的谓语动词又是be,在这种情况下,从句中的主语和be动词可同时省略.本句相当于
Unless (you are) invited to speak,you should remain silent at the conference.划（)是省略部分
