动词不定式的被动语态
动词不定式的被动语态

省略to的动词不定式在被动语态中如何应用,to该如何还原?
感官动词或使役动词使用省略to的动词不定式,主动语态中不带to ,但变为被动语态时,须加上to 。
例:make somebody do something→somebody+ be +made to do something
see somebody do something→somebody +be +seen to do something
A girl saw my wallet drop when she passed b y.→My wallet was seen to drop by a girl when she passed by.
The boss made the little boy do heavy work.→The little boy was made to do heavy work by the boss.
带有to的不定式怎样变被动语态?
比如:People oughtn't to criticze her for this matter.
ought to do中,to do并不是不定式,ought to 应看作一个整体,相当于一个情态动词,所以这个句子变不定式应按情态动词的变法:
can do --> can be done
ought to do --> ought to be done
People oughtn't to criticze her for this matter.
-->
She oughtn't to be criticized (by people) for this matter.。
英语语法之动词不定式

动词不定式语态
注意:1) 其他系动词如,look,appear等也可用于此句型 2) 不定式作为句子成分时,动词用单数形式。 3) 当不定式作主语的句子中又有一个不定式作表语时,不能用It is… to…的句型 (对)To see is to believe. 百闻不如一见。 (错)It is to believe to see.
动词不定式时态
1) 现在时:一般现在时表示的动词,有时与谓语动词表示的动作同时发生,有时发生在谓语动词的动作之后。 He seems to know this. I hope to see you again. = I hope that I'll see you again. 我希望再见到你。
注意:疑问词带不定式在句中作成分时,谓语动词用单数。 TБайду номын сангаасe question is how to put it into practice. 问题是怎样把它付诸实施。
3)当复合宾语中的宾语是不定式时,先用形式宾语it代替不定式,把不定式置于补语之后,即:主语+动 词+it+补语+to do句式。如: We think it quite important for us to learn a foreignlanguage well. He feels it his duty to help the poor. I find it difficult to learn English well.
被动语态详解

【被动语态详解】一、巧记各种时态的被动语态被动语态基本形式: be + done一般现在时: am, is, are + done一般过去时: was, were + done一般将来时: will + be doneam, is, are going to + be done过去将来时:would + be donewas, were going to + be done现在进行时: am, is, are + being done过去进行时: was, were + being done现在完成时: have, has + been done过去完成时: had + been done不定式:to be done介词:如without being done情态动词:can,may,must,should be done【点拨】1.被动语态是在主语和谓语动词之间存在逻辑上的被动关系时才使用的一种语态。
2.各种时态的被动语态都有一个明显的特点,既要体现出本时态,又要用上被动语态的基本形式be done。
现在进行时的被动语态构成是am, is, are + being done,可以这样理解:首先,它必须是现在进行时am, is, are + doing,同时它又必须是被动语态be done,所以be动词在现在进行时和被动语态之间起了一个衔接作用,即用being,这样being就把二者有机结合起来。
所以现在进行时的被动语态形式必须是也只能是am, is, are + being done。
同理可推出,现在完成时的被动语态形式应该是:既得是现在完成时have, has + done,又得是被动语态be done,所以be动词只有用过去分词been 才能把二者有机结合起来,即:have, has + been done。
其它时态的被动语态依此类推。
3.有些时态可以运用对比记忆法。
如现在进行时与过去进行时,一般将来时与过去将来时,现在完成时与过去完成时等只是在助动词上有所不同。
不定式在被动语态中的成分-充当成分-用法

不定式在被动语态中的成分-充当成分-用法当不定式的逻辑主语是不定式动作的宾语或承当者时,这个不定式要用被动语态。
(一般时态通常表示将来的动作;完成时态表示发生在谓语之前的动作)。
不定式的被动形式在句中可以用作主语、表语、宾语、主补语、宾补语、定语、动名词等。
1.用作主语。
例如:It is an honour for me to be invited to the party.我被邀请参加晚会,这是个荣幸的事。
2.用作表语。
例如:Nothing seems to have been forgotten.仿佛一切都记忆犹新。
The problem remains to be further discussed in detail.这个问题尚必须进一步具体讨论。
3.用作宾语。
例如:She asked to be sent to our college.她请求派到我们学院。
The students wanted to be given more experiments to do.同学们想多给些实验做。
More than half a century after his death,he continues to be read and quoted.他去世已经半个多世纪,他的著作持续为人们阅读和引用。
4.用作主语补语。
例如:Transistors are known to be widely used in radio industry.晶体管被公认广泛用到无线电工业中。
This book is said to have been translated into English.据说这本书已经译成〔英语〕。
5.用作宾语补语。
例如:He did not like his intention to be laughed at.他不喜爱自己的意图受到讥笑。
6.用作定语。
例如:This question will be discussed at the conference to be held next month.这个问题将在下月举行的会议上讨论。
不定式的被动形式用法

不定式的被动形式用法1. 概念理解英语被动语态的基本结构是“be+过去分词”,由此我们可以推出不定式被动式的构成即为“to be+过去分词”,如to be sold, to be studied, to be seen, to be given等等。
我们在学习英语语态时知道,只有及物动词才有被动语态,同样地,对于不定式来说,也只有及物动词的不定式才有被动式。
如果是不及物动词的不定式要用于被动式,要注意在其后加上合适的介词。
如:他不喜欢自己的想法受到嘲笑。
误:He did not like his idea to be laughed.正:He did not like his idea to be laughed at.2. 用法说明不定式到底用主动形式还是被动形式,往往取决于句子的意思,即意思上为主动就用主动形式,意思上为被动就用被动形式。
如:I wish to be excused. 我请求原谅。
“请求原谅”其实就是指“请求被原谅”,所以不定式要用被动式。
I had to shout to be heard. 我必须叫喊对方才能听得见。
“大声叫”的目的是什么?就是为了被别人听见,所以不定式要用被动式。
Rules were made to be broken. 定了规则就准备有人违反。
.根据常识可知,“规则”与“违反”之间是被动关系,所以不定式用被动式。
He was the last person to be asked to speak. 他是最后一个应邀请发言的人。
“应邀发言”实际意思是“被邀请发言”,所以不定式用被动式。
3. 主动表被动一般说来,表示主动意义,不定式用主动式;表示被动意义,不定式用被动式。
但是,有个别时候,虽然意义上是被动的,但不定式却要用主动式。
如:The house is to let. 此屋出租。
在英语中,to let, to blame这两个不定式在用作表语时,习惯上是用主动形式表示被动意义。
动词不定式的主动与被动形式

动词不定式的主动与被动形式动词不定式是一种非谓语动词形式,它由动词原形加上不定式符号“to”构成。

)3. They decided to go on a vacation together.(他们决定一起去度假。
)动词不定式的主动形式常常用来表示目的、意图、计划等。
二、动词不定式的被动形式动词不定式的被动形式表示动作的受动关系,即动作的承受者是主语。
在使用被动形式时,需要在“to”之后加上动词的被动形式,即“tobe + 过去分词”,例如:1. She hopes to be invited to the party.(她希望被邀请参加派对。
)2. They want to be recognized for their achievements.(他们希望因他们的成就而受到认可。
)3. He pretended to be surprised when he heard the news.(他假装听到消息后感到惊讶。
)被动形式通常用来表示动作的客观存在、被动接受等。
三、动词不定式主动与被动形式的用法1. 用于目的和意图动词不定式的主动形式常用于表示目的和意图,强调主语的主动性。
例如:- I bought a book to improve my English.(我买了一本书来提高我的英语水平。
)- He practices yoga every day to stay healthy.(他每天练习瑜伽保持健康。
