According to what he complained about,something must have gone wrong with the computer,______?
According to what he complained about,something must have gone wrong with the computer,_didn't it_____?
这里没有表过去的时间状语,为什么用didn‘t,而且助动词是have,表过去的话,不应是hadn’t吗?

must have gone wrong,其实是虚拟语气,是对过去的一种猜测,但是整体基调还是过去式,accroding to what he complained about就可以看出,something must have gone wrong with the computer这句话是推测,所以用的是虚拟语气,用must have表虚拟,但是didn't it 这段就不是虚拟了,问的是现实.其实意思就是,根据他抱怨的,电脑肯定出问题了（说话者的推测）,不是么（难道事实情况不是如此么?）所以用的是didn't it.
不懂欢迎追问,
再问：所以说是不是先要看，是不是事实？那有没有用haven‘t的情况，举个例子
再答： must +have +过去分词的结构，表示对过去发生行为的推测，含有“一定”、“准是”的意思。
如你举的例子翻译为：YOU must have been there before ，（）？你以前一定去过那，是吗？反义疑问句问句要根据陈述部分中有无明确的过去时间状语）来确定：如果有（像last week，yesterday等之类的这种表示过去的时间状语），要用“didn't+主语”或“wasn't/weren't+主语”如：you must have read that book last week ,didnt you?；如果没有明确的过去时间状语，则强调动作的完成，问句要用“haven't/hasn't+主语”(而且你提到的句子中before这个词也是完成时的标志)。你这个句子没有特别的时间表示，但是go wrong 一般我没见过完成时态，一般都是一般现在时或者一般过去时，所以用didn't it 。其他很多都可以使用haven't +主语。比如说：you must have been here before, haven't you? 这是您想了解的吗？

According to what he complained about,something must have go What about to have something with me?翻译 he (complains还是complained) about 为什么 He must have not had enough money to get something .这个句子中mus what about something eat?it is time to go and play game.all What do you think about Cindy according to the passage? what about something to drink?怎么翻译 what about something to eat翻译 What about something have?改错A.what B.about C.something D.hav Secondly,you must take enough time to study something about he will have to stay in hospital. that's what he must do .这是 He must have been annoyed by something yesterday,_____?
