4.You won't study well ______ you really know how to study.( )| A. | if | B. | when | C. | unless | D. | after |
分析 除非你真的知道如何学习,否则你不会学好.
解答 答案:C;if,如果;when,当…的时候;unless除非;after在…之后;根据句意,"You won't study well 你不会学好"和"you really know how to study你真的知道如何学习";可知,后句是前句的条件,而且是否定的条件,用unless引导;unless=if not"除非,如果不";故选C.
点评 连词在句子中主要起联系上下文的作用,他们之间的区别就是表示逻辑关系的不同,所以在解题时先要理解上下文含义,然后根据上下文逻辑关系选择合适的连词.
