6.______children believe they can succced,they will never become totally independent.( )A. | If | B. | Though | C. | When | D. | Unless |
分析 除非孩子们认为他们能够成功,否则他们将永远不会变得完全独立.
解答 答案D.if"如果",引导条件状语从句.though"尽管,虽然",引导让步状语从句.when"在…时候",引导时间状语从句.unless"除非,如果不",在意义上相当于if…not,因此在有些场合中unless与if…not可互换使用,引导条件状语从句.分析可知前后两句之间是逻辑上的"条件"关系,可排除B和C两项;再根据句子所表达的意思可排除A,故答案选D.
点评 本题考查从属连词的用法.连词的用法辨析,要注意分析主从句之间的逻辑关系,再确定相应的连词,同时注意不同的连词的语义及用法区别.
本题尤其要注意区分unless和if的用法.unless在意义上相当于if…not,因此在有些场合中unless与if…not可互换使用.
如:Unless I am mistaken,I've seen that man before.=If I am not mistaken,I've seen that man before.如果我没搞错,我以前见过那个人.
