问题描述：
where have you bought it和where did you buy it有什么区别
答
在口语中两个句子的意思是相同的.第一个句子用的现在完成时,强调购买对现在的影响,而第二个句子强调购买这个动作,如果加上一个过去的时间词,就只能用第二个句子,如：
Where did you buy it yesterday?那有twice， ever ，never ，yet ，just 等等带着的用什么以上这些词也要看具体的语境，一般而言，只要有过去具体时间的句子，都用过去时。如：I have been to the Great Wall twice.I went to the Great Wall twice last year.可以是i have seen it twice吗可以的。
