反义疑问句详
反意疑问句是英语四大问句之一,它是由一个陈述句加上一个短问句而构成的.反意疑问句的基本构成形式是：陈述句+动词(肯定或否定)+主语?如：
①She often has lunch at school, doesn’t she? ②You don’t like sports, do you?
使用反意疑问句要注意以下若干对应规则：
一、 反意疑问句中问句部分的动词与陈述部分的动词在语气上成相反的对应关系,即：
肯定+否定? 否定+肯定?如：
①You can’t do it, can you? ②They are very late for the meeting, aren’t they?
二、 反意疑问句中问句部分的动词与陈述部分的动词种类要对应一致.如：
①He has supper at home every day, doesn’t he? (不能用hasn’t he?)
②They have known the matter, haven’t they? (不能用don’t they?)
三、 反意疑问句中问句部分的动词在时态上应和陈述部分的时态一致.如：
①They will go to town soon, won’t they?(不能用don’t they?或 aren’t they?)
②He works very hard, doesn’t he?(不能用didn’t he?或won’t he?)
四、 反意疑问句的陈述部分含有由un-, im-, in-, dis-, 等否定意义的前缀构成的词语时,陈述部分要视为肯定含义,问句部分用否定形式.如：
