题目内容
10.Your dream won't come true ______ you know what your dream is.( )| A. | after | B. | unless | C. | while | D. | since |
分析 你的梦想不会成真,除非你知道你的梦想是什么.
解答 答案:B 本题考查的是从属连词的辨析.after 之后,以后;unless 除非;while 然而,当…时;since 自从.根据题意,从前半句你的梦想不会成真和后半句你真的知道你的梦想是什么来看,这里需要一个表假设的连词,主句用一般将来时从句用一般现在时说明后句是表假设的条件状语从句,结合选项,unless可以引导一个表假设的条件状语从句,意为"除非",相当于if not.故选B.
点评 本题考查的是从属连词的辨析,应审清题意,并结合语境,从而选出正确答案.
