Question

Jane told me she would not attend the conference ______.

A.if she invited                                                B.when inviting

C.unless invited                                                D.while inviting

Answer 1

C

解析:

選項(xiàng)為省略句，當(dāng)when,while,until,if,unless等連詞引導(dǎo)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。
