Unless _____ to speak,you should remain silent at the conference.
问题描述:
Unless _____ to speak,you should remain silent at the conference.
A.invited B.inviting C.being invited D.having invited
为什么选A不选C,unless也可以看作是介词,后面加动名词
动名词不是不表进行的吗~
答
完整的句子是Unless (you were)invited to speak,you should remain silent at the conference.
you were 是省略成分,这是我的理解.
选择C.being invited ,则翻译成你正在被邀请,语意不通顺.
