题目内容
7.Only a few students in our class have computers at home,__________?( )| A. | do they | B. | don't they | C. | are there | D. | have it |
分析 我们班只有几个学生在家里有电脑,是吗?
解答 答案:B.
根据Only a few students in our class have computers at home,可知句意"我们班只有几个学生在家里有电脑,是吗?".反意疑问句通常遵循前肯后否,或前否后肯的原则.根据Only a few students in our class have computers at home,可知句子是肯定形式,这里have是实义动词.句子叙述一件事实,所用的时态是一般现在时,所以疑问部分用否定形式don't,人称 students 是复数,因此用they代替.故选B.
点评 反意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.
