hAving DonE 作状语

having前面 有个短语是 介词,应该是have done,应该是完成时的语态~~

您提出来的having done是指现在分词的完成形式作状语,表示这动作在谓语所表示的动作之前发生,通常情况是如您所言.Having driven all day,we were rather tired.(having driven表示的"先时性的行为") 常见的例外是从属关联词 after 引导的从

当然可以.位置不受限制.只是若是简单句好像放在开头的多点.Having finished his homework , he went home. having done 这种结构是现在分词的完成式,它所表示的动作先于谓语动词的动作.就比如上面的那个句子,是先完成,后回家.就是如此.

当然不是 having done可以看作是分词的完成式,或者是动名词的完成式 如果是分词,基本上都是充当状语 如果是动名词,那就是充当主语或宾语了 请看例句:分词作状语:Having finished his homework, Tom went home. = After Tom finished his homework, Tom went home. 强调汤姆在完成作业后才回家的,表示分词的这个动作先于回家的这个动作.动名词:I regret having made the same mistake again. 我很后悔又犯了同样的错误,强调动作已经犯了.望采纳!

done 表示被动或完成.being done 表达被动进行.例如:Compared with China, Japanese is much smaller.与中国相比,日本小得多. (表示被动). praised by her teacher, she was very happy.(表示被动完成) Being questioned by the police, he felt terrible. (正在被警察审问) 希望对你能有所帮助.

1. 两者的确很难区分,主要区别有以下两点.1)having been done一般强调被动的动作,而且该动作必须和主句动作之间有着明显的时间/逻辑上的先后/因果关系,且隐含having been done的动作不会再进行的意味.2)done做状语时更多时候强

表示动作发生在谓语之前.如having finished my job , I went home .

done 表示被动或完成.being done 表达被动进行.例如:Compared with China,Japanese is much smaller.与中国相比,日本小得多.(表示被动).praised by her teacher,she was very happy.(表示被动完成) Being questio

having been done 做状语表示该动作发生在主句动作之前;而done则不强调这层含义;举个例:Having been killed, she couldn't stop her blood from going chilled.和Killed, she couldn't stop her blood from going chilled.前边一句稍微强调“再她的血变冷之前她被杀的”而后者没有强调动作先后的含义.(需要说明一下done指的是普遍意义的过去分词而不是单纯的done)

现在分词就是动名词啊,,只是叫法不一样,但是都是动词的ing形式,也就是V-ing,表示动作的主动发生.用到having done 是在句中能体会到两个动作的先后发生顺序,表达动作的先发生并且已经完成就用having done ,做伴随状语,但是要与主句的主语一致,才能这样表达.例如:Having done his homework,he went shopping with his father.
