题目内容
13．I think he is a student，____？（ ）| A． | don't I | B． | isn't he | C． | is he | D． | do I |
分析 我认为他是一名学生，不是吗？
解答 答案：B．考查反意疑问句．句意"我认为他是一名学生，不是吗？"．对于think引导的复合句，通常以从句的意思而定来写反义疑问句，前句是肯定的，后句应用从句的否定结构为isn't，故本题选B．
点评 反义疑问句由两部分组成：前一部分是一个陈述句，后一部分是一个简短的疑问句．主要形式：陈述部分肯定式+疑问部分否定式；陈述部分否定式+疑问部分肯定式．要注意人称，时态变化，及一些特殊用法．
