Mario, you used to be short, didn’t you (p25-1a) 【剖析】 本句是used to do的反义疑问句, used to do“过去常常做某事”，其反义疑问形式有两种：usedn’t sb / didn’t sb 基本用法： 反义疑问句的特点是：前肯后否，前否后肯。而且附加疑问句的动词在时态、人称、数等方面必须与前半句的动词相呼应。 Mary is very lazy, isn’t she They were not late for the meeting, were they 反义疑问句的回答要根据实际情况作答，与疑问句本身的肯定还是否定没有关系。也就是说对反意疑问句的回答，不管问题的提法如何，如果事实是肯定的，就要用yes，事实是否定的，就要用no。 --He is good at English, isn’t he --Yes, he is. --They don’t go to Shanghai, do they --No, they don’t. (是的，他们不去) 如果陈述部分带有一些不易察觉的否定意思的词如：little, nothing, few, seldom, hardly等，附加疑问句要用肯定形式。 They hardly ever see the film, do they There is little water in the glass, is there 反义疑问句的常考句型： There is a book on the desk, isn’t there To see is to believe, isn’t it I don’t think he can swim, can he Tom lived in London, didn’t he 祈使句的反意疑问句，一般在句末用will you，而以let’s开头的祈使句，其附加疑问句部分用shall we。 Come here earlier next time, will you Let’s have a rest, shall we 1.
