You will not succeed ______ you work harder.A.ifB.whenC.unlessD.because.

题型:不详难度:来源:
You will not succeed ______ you work harder.
A.ifB.whenC.unlessD.because.

答案
C
解析

试题分析:根据语境可知此句的含义是你不会成功除非你努力工作。考查的是连词的基本用法,根据选择项的提示可知if引导的是条件状语从句,when引导的是时间状语从句unless引导的是让步状语从句because引导的是原因状语从句。A,B和D都不符合句意,故选C。
点评:unless是从属连词,引导条件状语从句,含有否定意义,相当于if条件状语从句的否定形式。所以unless =" if" not。注意:unless引导的条件状语从句和if条件状语从句,与其它时间状语从句一样,用一般现在时代替将来时。
