题目内容
14.I didn't realize he was a famous scientist ______ you told me.( )| A. | until | B. | because | C. | since |
分析 直到你告诉我,我才知道他是一位出名的科学家.
解答 答案:A 根据句子结构 I didn't realize he was a famous scientist ______ you told me,本题考查固定句式not…until…直到…才,其用法是如果(主)句中的谓语动词是终止性动词,应采用"…not…until…"结构,意为"…到…时候才…",结合选择,故选A.
点评 用终止性动词作谓语时,until既可以和not连用,又可以和never,nobody,nothing,few,little,seldom,hardly等含否定意义的词连用.例如:I had not seen him until 1990.(=I had never seen him until 1990.)
1990年以前我从未见过他.
