完成时的否定It has often been said
这句话的否定是什么

it has not been said 可以与it is said 等相互代替意思都是据说…….has在这里是 have的一般现在时态下的单数第三人称形式在这里帮助构成现在完成时所以这里的have/has 是一个助动词其任何助动词系动词标注的情态动词都可以自身完成否定直接加not.帮助一般现在时的实意动词构成否定加 do not单三人称does not 一般过去时的实习动词否定只有did not

完成时的否定It has often been said It has often been said 和 It has been often said 有什么区别 It has often been said that life is difficult as it is He has often been there.不用完成时怎么说与it has been said 类似的句子还可以怎么说? It is said _____ has been translated into French. 英语完成时It has been raining for three hours.为什么要加been?加been不是表 it has been said与 it is said使用上有没有什么差别有关英语的问题He has been working all day.他整天都在工作.这个现在完成进行时的句子能变成否定 it is/has been+时间段+since since后面接完成时还是一般过去? it's been.的全称是不是 it has been... it has been a
