Question

Jane told me she would not attend the conference ________.

A. if he invited　　 B. when inviting

C. unless invited　 D. while inviting

 

Answer 1

C

 

選項為省略句，當when, while, until, if, unless等連詞引導的狀語從句的主語與主句的主語相同，從句的主語及部分謂語（be動詞）可省略。unless invited =unless she was invited。又如： When asked about his discovery, Sir Alexander Fleming said: “One sometimes finds what one is not looking for.”
