问题描述：
you bought a new computer last week,_____ you?
讲讲为什么？
答
填：didn't
反义疑问句
因为主语中you bought a new computer last week,的动词是bought,是实义动词,并且是过去式,变反义疑问句的时候,要用助动词did+not→didn't 来完成再举些例吧！比如后面部分应与那些构成?比如didn't是did与not构成？反意疑问句的回答：前肯后否，前否后肯，根据事实从后往前翻译。如：（1）They work hard,don’t they?他们努力工作，不是吗？Yes, they do.对,他们工作努力。/No, they don't.不，他们工作不努力（2）They don’t work hard, do they? 他们不太努力工作，是吗？Yes, they do. 不，他们工作努力。/No, they don't. 是的， 他们工作不努力如果句子中的实义动词是过去式，就用did来变，和上面一样有没有不用do或did的？有。 如果动词是be动词，就直接在be动词上变。例如：He is a teacher, isn't he?He isn't a teacher, is he? 过去时态He was a teacher, wasn't he?He wasn't a teacher ,was he?
