题目内容
19.Be quiet_____you will wake the whole house!( )
| A. | or | B. | and | C. | so | D. | but |
分析 安静,否则你要把整栋房子的人吵醒.
解答 答案:A.这是句型祈使句+and+陈述句的变化式,祈使句表条件,陈述句表结果,若前后句子是顺成关系,用and,反之用or,这时的or是"否则"之意,而不是"或者"之意,根据句意,只有A填入空中,意思才通顺,符合逻辑.其它几个and,和;so,因此;but,但是,填入空中,要么句意不通,要么不合逻辑.
点评 这是考查并列连词的用法,同学们一要前后句子的准确意思,理顺它们之间的关系;二要掌握并列连词的用法,再结合题干仔细斟酌,确保前后意思通顺,符合逻辑,最后定夺答案.
