He decided not to say anything at the meeting unless_________. A．asking to B．to ask to C.

He decided not to say anything at the meeting unless_________. A．asking to B．to ask to C．asked to D．ask to

Answer 1

C

试题分析：考查非谓语动词和省略。He与ask之间是动宾关系，即“让他说”，应该用被动，排除A、B、D；句意：他决定在会议上保持沉默，除非被邀请才讲话。unless后省略了he was asked to say something。故选C。
