Question

【题目】I knew nothing about it ______ he told me.

A. ifB. untilC. since D .after

Answer 1

【答案】B

【解析】

句意：直到他告诉我，我对此事一无所知．A.如果；B.直到；C.自从；D.以后。根据固定结构"not…until…"意思是"直到…才…"根据"I knew nothing about it"我对此事一无所知。这个句子可以变为"I didn't know anything about it"结合给出四个选项，因此可知这句话的意思是"直到他告诉我，我对此事一无所知。"此空故填until，故选B。
