题目内容
3.I guess you must have had milk and bread for breakfast this morning,__________?( )A. | don't I | B. | haven't you | C. | didn't you | D. | mustn't you |
分析 我猜,你今早的早饭肯定是牛奶和面包,不是吗?
解答 答案:C
根据题干中主句的主语是第一人称I,主句的谓语动词是guess可知,此主从复合句的反义疑问部分需同从句的主语和谓语保持一致,即对从句提问.再由从句的谓语部分must have done可知,must是对过去情况的推测,因从句中有明确的过去时间状语this morning,所以,在此情况下,反义疑问部分的助动词用did,主语和从句的主语一致为you.反义疑问的基本原则是"前否后肯,前肯后否".所以此句的反义疑问句为didn't you?.故选C.
点评 此题相对而言比较复杂,在了解反义疑问句的基本原则"前否后肯,前肯后否"的基础之上,不仅要知道复合句的反义疑问句用法还要知道must表推测时的反义疑问句用法.通常情况下,复合句的反义疑问句都对主句提问.但是,若主语的主语是第一人称且主句的谓语动词为think,believe,suppose,expect,imagine,guess等时,反义疑问部分需同从句的主语和谓语保持一致,还要注意否定前移.陈述句中含有表推测的must时,若句中有明确的时间状语,则根据时间状语表示的实际情况而定.
