hadn't done为过去完成时的否定
其他完全正确，很聪明！

是的，但也有其他的否定词可表否定，如never

现在完成时的否定形式，主语是复数或第一二人称时用haven't done ，主语为“单三”时用hasn't done。hadn't done是过去完成的否定式。

现在完成时的否定是haven't done 或hasn't done ；过去完成时是hadn't done

一般过去时的否定是didn't do,现在完成时的否定是haven't done 或hasn't done 或hadn't done use to do的一种否定 形式是：didn't used to和didn't use to ? 一般过去时的否定形式?was'were+not和在行为动词前加didn't.这两者是通用的吗?如果通用,那I didn't know you like coffee.换成另一种表达方式是什么?Thanks for your answer! used to do的否定used to do正式的否定形式是used not to do,口语中可以说didn't use to do .我想问,其他动词的否定都是在其前面加didn’t或者don't等助动词,为什么used to do的正式的否定形式要在used后面加 i didn't believe they could do the work 是否定转移吗否定转移,要求主句是什么时态 be used to do sth.否定形式是什么?也就是说,didn't used to do 还是didn't use to do 求英语被动语态疑问句 肯定句 否定句 的总结打个例子是主动语态的一般过去时 肯定：主+do 否定句：主+don‘t do 疑问句：do+主+do一般现在 一般过去 一般将来 过去将来 现在进行 过去进行 有关一般过去时的.那个句子的意思是,她不是去看电影在某某时间.让我们用括号里的适当形式填空.括号里的内容是（not go）请问这两个词怎样变成否定的过去式呀?是didn`t go 还是wentn`t?我想 英语的一般过去时在一般过去时里：didn't＋动词原形,那么did也是加动词原形吗? He didn’t go to bed until twelve o‘clock last night这句话中的didn't go为什么用didn't而不用肯定的词语,句子中didn't是否定的吗not.until是直到. He didn’t go to bed until twelve o‘clock last night这句话中的didn't go为什么用didn't而不用肯定的词语,句子中didn't是否定的吗not.until是直到. They both didn't do their best.是全部否定还是部分否定?Not both of them...和Both of them didn't...才是部分否定?但我很肯定地见到Not all men are clever=All men are not clever,那么Both of them didn't...怎会是全部否定呢 把一个一般过去时的英语句子改为现在完成时!He laughed,byt didn't answer my pusetion.用has改错了~是but不是byt,实在不好意思！ we diceded to have a fashion show this weekend.(改为否定句)我们学的短语是decide not to do sth .可答案是didn't decide to have .到底怎么用. They didn't do their homework last night改为否定疑问句 all of us didn't like是部分否定吗详解部分否定 All of us didn't go there yesterday.是部分否定还是完全否定? 一般过去时的肯定,否定,疑问的结构.
