He kept the machine running all the time.他一直让机器开着。Wh kept yu frm taking part in the summer camp?谁阻止你参加夏令营?
重点语法现在完成时的被动语态一、现在完成时的被动语态的构成
二、现在完成时的被动语态的用法1.表示一个被动动作发生在说话之前,强调对现在造成的影响和结果。The huse has been cleaned by my hme rbt.房子已经被我的家庭机器人打扫干净了。All the preparatins fr the task have been cmpleted.这项任务的所有准备工作都已完成。2.表示一个被动的动作或状态开始于过去,持续到现在,并可能持续下去,常与fr或since引导的时间状语连用,或用于Hw 句型中。Hw lng has the bk n cmputers been kept?这本有关电脑的书借了多长时间了?Mre than 20,000 cmputers have been made in the factry since last mnth.自从上个月起,这个工厂已生产了20 000多台电脑。
三、短语动词的被动语态1.短语动词是一种固定的词组,由“动词+副词”或“动词+副词+介词”构成,其作用相当于一个动词。(1)“及物动词+副词”“及物动词+介词”以及“及物动词+副词+介词”构成的短语动词可用于被动结构。At last they put ut the fire.→At last the fire was put ut.Have yu sent fr a dctr?→Has the dctr been sent fr?My classmates caught up with me in this exam.→I was caught up with by my classmates in this exam.
(2)许多“不及物动词+介词”以及“不及物动词+副词+介词”构成的短语动词相当于及物动词,也可以有宾语,也可用于被动结构。The bys laughed at him fr the flish mistake.→He was laughed at fr the flish mistake.注意:短语动词是一个不可分割的整体,在变为被动语态时,不可丢掉构成短语动词的介词或副词。We must take gd care f the yung trees.→The yung trees must be taken gd care f.
2.带有双宾语的句子在变为被动结构时,这两个宾语的任何一个都可作被动句的主语。(1)把间接宾语改为被动语态的主语,直接宾语仍保留原位。(2)把直接宾语改为主动语态的主语,此时,间接宾语前要加介词t或 fr。He gave the by an apple.→The by was given an apple./An apple was given t the by.Her father bught her a present.→She was bught a present by her father./A present was bught fr her by her father.
3.带复合宾语的动词在改为被动语态时,一般把主动语态的宾语改为主语,宾语补足语在被动语态中作主语补足语。We call him Xia Wang.→He is called Xia Wang.He cut his hair shrt.→His hair was cut shrt.注意:主动语态中不带t的动词不定式作宾语补足语,改为被动语态时不定式前要加t。They watched the children sing that mrning.→The children were watched t sing that mrning.
