题目内容
16.-You will fail in the exams ________ you work hard.-I know,Dad.I'll try my best.( )
| A. | if | B. | unless | C. | although |
分析 -除非你努力工作,否则你会考试不及格的.
-我知道,爸爸,我会尽力的.
解答 答案:B;if,如果;unless除非;although虽然;根据句意,"You will fail in the exams你会考试不及格的","you work hard你努力工作",可知后句是前句的条件,而且是否定的条件;用unless=if not;意为"除非,如果不".故选B.
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.
