you bought a new computer last week,_____ you?讲讲为什么?
you bought a new computer last week,_____ you?
讲讲为什么?

you bought a new computer last week,_____ you?讲讲为什么?
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

didn‘t

bought 的现在时是buy , 句子的意思是, 你上个星期买了一台新电脑不是吗?
反义疑问句,后面是难到你没买吗? 双重否定就是肯定你买了!
Did not you buy a new computer last week ?
