题目内容
19.Tony is a determined person.________ he has a dream,he will try his best to realize it.( )A. | Unless | B. | Since | C. | Once | D. | While |
分析 托尼是个意志坚定的人,一旦有了梦想,他就会尽最大的努力去实现它.
解答 答案为C
unless"除非,如果不",引导条件状语从句;since"因为,自从";once用作连词时,意为"一旦…就…",相当于as soon as; while"当…的时候,只要,尽管".联系前后语境,并根据Tony is a determined person这个前提,可知他应该是"一有了梦想,就会尽力去实现",选项C.Once符合语境.
点评 本题是连词的辨析题.在熟悉常用单词的基本词义基础上,我们还要掌握常用词汇的不常用或特殊用法,从而获取正确答案.
