问题描述：

答

现在完成时态可以直接表示某种状态
例如：She has been here for more than 1 year.她在这里呆了一年多了
同时后面可以加done 构成 have/has been done 表示现在完成时的被动
例如：The building has been set up since 1998.这个建筑物自从1998年就建成了.
当然后面还可以加doing 构成 have/has been doing 表示现在完成时的进行时
例如：She has been practising this for many years.她练习这个很多年了
希望能够帮到楼主

there have been 和there has been是怎么用的
‘Of ’在此处的用法作何解释?原句：Of particular interest has been the effect of contract violation,请问该句的第一个Of 是怎么用的,我怎么没见过这种语法规则所在段落如下The concept of the psychological contract in its broadest sense has been in use for some time ,but only recently has research attempted to specify and empirically examine what is implicit in terms of reciprocity and exchange within the employment relationship and the effect these beliefs have on key employee and organizational outcome
现在完成时 have been 被动语态时用have been 但这两句话我没觉得是被动语态啊 1.the vicar has been现在完成时被动语态时用have been 但这两句话我没觉得是被动语态啊1.the vicar has been asked to have the tree cut down2.where have you been hiding求解
6 help!help!关于英语时态选择题,在此跪求大家了,谢谢谢谢谢谢谢!6.The little boy is dirty from head to foot because he ( ) in the mud all morning.A.has played B.is playing C.has been playing D.was playing答案:CQ:为什么不用过去进行时态表示小男孩整个早上都在玩,那么对于这到题现在完成进行时态has been playing和过去进行时态was playing 有什么区别,用现在完成时态has played 行不喃.又和前两个时态比较喃?现在完成时have done分为两种 1.动作未完成 2.动作已完成所以理论说 has played 可以表示现在还在玩啊~
是不是某些情况下用完成时态和过去时态都可以?背景是,我前几天让Mary送一些文件过去给对方,但是对方发信说没有收到,并且请尽快送来.于是我确认了一下,发现M确实已经送去,所以回信告诉对方.可以用I confirmed with Mary,and the paper was sent to you.表达么?还是应该用I have confirmed with Mary,and the paper has been sent to you.到底用完成时态还是用过去时态?都可以么?什么情况下可以没有区别?完成时态是对现在有影响的过去动作，关键怎么区别对待对现在有没有影响啊？这个句子有人给我讲说是可以用过去式的，也可以用过去完成表示强调对现在有影响。
他出国了英语怎么说?（新概念）他过出国英语怎么说他回家了英语怎么说他去过那英语怎么说他去那了英语怎么说他来过这英语怎么说他来这了英语怎么说用 has been to has gone to
I think she was retiring She can't have been retiring 这两句怎么翻can't have been 后面跟进行时时则表示对过去正在进行的动作的猜测.那retire 是退休的意思退休就退休了难道还能持续的退休吗?还有第一句用的是过去进行时,如果按照有些进行时有将来时的意思是否可以理解成过去将来时意思就是我想她快要退休了.第二句
现在完成进行时存在被动语态吧?之前,我以为没有.今天在百度上查到好多资料说的是有的,1 现在完成进行时的被动态:have / has been being done呵呵.2 我的显示器已经使用了8年.我用现在完成时被动语态翻译好呢,还是用现在完成进行时被动语态翻译好?我这想表达还会继续用下去,我倾向于现在完成进行时,但是现在完成时,也能表示有可能继续吧?怎么选择好.3 现在完成时,可以表示动作从过去延续到现在,动作可能已经结束,也有可能继续下去现在完成进行时也表示动作将继续下去,那是不是两个时态可以互换了呢?
a variety of句中动词单复数A wide variety of opinions have been expressed on the plausibility of these threats.和A considerable variety of opinions on this subject has at different times been advanced from the earliest times.都是 a variety of opinions为主语,为什么一句用单数一句用复数?这个是《英语语法实践指南第四版》主谓一致里面的。书上说通常a variety of+复数名词+复数动词，后面又写a variety of也见于这样的句中（第二句）。第二句到底特殊在哪里了？非要让a variety of 这么用？
have been study 为什么不说have studied ,have been absent 为什么不说have absented1 have been study 和 have been absent最常见到,既然不是被动语态（主语是人）,为什么不直接用have + 动词过去分词的形式呢?2 have absented 我也看到过不知道和have been absent 有什么区别（study和absebt在这都不做动词用了这我知道,我就是不知道为什么要这么用,是习惯用法吗?）3 另外 how long has she been study与 how long has she been studying只有语境上去区别对吧,意思都是一样的,用studying强调还会继续学习下去,但是study在这也暗示会继续学习下去吧.
