主动句改被动句英语题
改被动句要保持原句时态,第一句话paid是过去时,所以应该改为: Much attention was paid to his task by him.
第二句took 也是过去式,应该改为:
主动句变被动句
主动句变被动句可按以下步骤进行。
1、主动句变被动句的实质是将主语和宾语的位置对调,动词由原来的形式变为be加上动词的过去分词。如不需要突出动作的执行者,也可不要by-词组。 They punished the criminal.----- The criminal was punished.
2.如果主动句带有情态助动词或半助动词,在变为被动句时,情态动词或半助动词保持不变,谓语动词由主动变为被动。
They should do the work at once.----- The work should be done at once.
They must have finished their work.----- Their work must have been finished.
He is likely to let you down.------ You are likely to be let down.
3、如果主句是双宾语结构,变为被动句时刻有两种形式:一种是以间接宾语作主语;另一种是以直接宾语作主语。
They offered him some assistance.----- He was offered some assistance.
4、如果主句的结构带有宾语补足语,变被动的时候要将原来的宾语补语变为主语补语。
We have painted the windows white.----- The windows have been painted white.
They elected Tom monitor of the class.---- Tom was elected monitor of the class.
5、当主动句变为被动句时,有时用by-词组,有时不用。一般来说,当施动者为谁不太清楚、不甚重要或不愿说出时,通常不用by词组。但有时为了强调施动者,则须用by词组。
Hamlet was written by Shakespeare.
Susan was cheated by David.
有时为了避免中途变更主语,不得不用被动句而把施动者置于by-词组中。
主动句变被动句训练
The song is often sung by the students in English.Last week a letter was sent to me by her.Liming was seen to sweep the floor by me this morning.The lights must be turned off by you before leaving.The problem can be worked out by him.(一)主动语态变为被动语态,要把主动语态句中的宾语为为被动语态句中的主语;主动句中的主语在被动句中作介词“by”的宾语,构成由“by”引起的短语(这个短语在不强调施动者时可以省略);主动句中的主语也可作其他介词(如“in”)的宾语,构成地点状语。 (二)如果主动语态句中有直接宾语和间接宾语,变为被动语态时,有两种变化:把指人的间接宾语作被动句中的主语,并将此宾格人称代词变为主格人称代词,而指物的直接宾语保留不变;或将指物的直接宾语变为被动句中的主语,间接宾语保留不变。如果间接宾语作保留宾语,其前可用介词to。(三)如果主动语态句中的宾语是人称代词宾格,宾格补语是一个名词的话,变为被动语态时,应把宾语改作主动句的主语,而宾语补语保留不变。(四)带有复合宾语的主动句变为被动句时,复合宾语的一部分(宾语)成为主语,剩下的部分(宾语补语)就成为主语补语,它们多为不定式、分词,也可以是名词和形容词。在see,make,feel,watch,hear,notice,help,have等动词后的复合宾语中,如果宾语补语是动词不定式,则不定式to须省略。但在被动句中作主语补语的不定式必须有to。 (五)带介词或副词的短语动词(如look after,put on, pay attention to)用作被动式谓语时,它们原来所带的介词或副词应保留下来。 (六)被动语态中的时态应与主动语态中的时态一致(见上面的例证)。假如主动语态中的时态是进行式,应特别注意;被动语态中的进行式要用be-ing。
怎么把主动句改为被动句英语
您好,领学网为您解答:
主动句改被动句时,一是时态不能改变;二是变为被动语态后,谓语动词要和被动语态的主语在人称、数上保持一致。还要作如下变动:把主动语态的宾语变为被动语态的主语;主动语态的主语放在by的后面,组成介词短语,再把这个介词短语放在被动语态的谓语动词之后。在动作的执行者无须说明或不必要强调时,by短语可以省略。例如:
They will open a new supermarket there soon. 他们很快将在那里开办个新超市。
A new supermarket will be opened there soon. 一个新超市不久将在那里开办。
The doctor gave two lectures in English. 那位医生用英语讲了两次课。
Two lectures were given by the doctor in English. 由那位医生用英语讲了两次课。
