10.I didn't believe he could drive he told me.( )| A. | once | B. | while | C. | since | D. | until |
分析 我不相信他会开车了,直到他告诉我.
解答 答案D.once意思是"一旦"引导时间状语从句;while意思是"与…同时"引导时间状语从句;since意思是"自从…以来"引导时间状语从句;until意思是"直到…才"经常和not连用,构成短语:not…until…意思是"直到…才…"引导时间状语从句.结合"I didn't believe",结合给出的四个选项,可知要用until和not搭配,构成短语:not…until…,所以要用until,故选D.
点评 首先要掌握这几个从属连词的意思及用法,然后根据具体的语句,结合给出的选项,就可以做出正确选择.
