各种时态的被动语态
被动语态概述
被动语态的概念:它是动词的一种形式,表示主语与谓语之间的执行或被执行关系。主动语态表示主语是谓语动作的执行者,例如:They saw the little boy crying by the river。被动语态表示主语是谓语动作的承受者,例如:The little boy was seen crying by the river。
被动语态的构成
被动语态的形式是由“助动词be+动词的过去分词”构成。助动词be随着主语的人称、数、时态等的不同而变化。几种常见时态的被动语态形式如下:
1、一般现在时am/is/are +过去分词
例如:Rice is planted in the south of China。
2、一般过去时was/were +过去分词
例如:These trees were planted the year before last。
3、一般将来时will/shall + be +过去分词
例如:A sports meeting will be held next week in our school。
4、现在进行时am/is/are + being +过去分词
例如:Your radio is being repaired now。
5、过去进行时was/were + being +过去分词
When he got there, the problem was being discussed。
6、现在完成时have/has + been +过去分词
His work has been finished。
Has his work been finished? Yes, it has。 / No, it hasn’t。
7、过去完成时had + been +过去分词
注意:
1、除了be之外的其它系动词如get, stay等也可以和过去分词构成被动语态。例如:Their questions haven’t got answered。
2、含有情态动词的谓语变成被动语态使用“情态动词+ be +过去分词”结构。例如:
More attention should be paid to the old in this country。
This work can’t be done until Mr。 Black comes。
3。含有“be going to”, “be to”等结构的.谓语,其被动语态分别用“be going to + be +过去分词”和“be to + be +过去分词”。例如:
The problem is going to be discussed at the next meeting。
All these books are to be taken to the library。
4、被动语态与系表结构的区别:“连系动词+用作表语的过去分词”构成的系表结构,与被动语态的形式完全一样,所以应注意它们的区别。被动语态中的过去分词是动词,多强调动作;系表结构中的过去分词相当于形容词,多强调状态。前者通常可用by引出动作的执行者,而后者则不可以。例如:
The map was changed by someone。(被动结构)
That custom remained unchanged for many centuries。(系表结构)
系表结构中的过去分词通常可被very修饰,被动语态中的过去分词往往要用much修饰。
例如:
He was very excited。(系表结构)
He was much excited by her words。(被动结构)
5。主动形式表被动意义。有些动词的主动形式有被动意味,如open, read, sell, shut, wash, wear, write等。此时句子的主语一般是物。例如:
These books sell well。这些书很畅销。
The door won’t shut。这门关不上。
The clothes wash well。这些衣服很好洗。

一. 直接引语和间接引语
一直接引述别人的原话,叫做直接引语;用自己话转述别人的话,叫做间接引语。间接引语一般构成宾语从句。直接引语必须放在引号内,间接引语则不用引号。直接引语改为间接引语时,除将引语部分变成宾语从句外,还必须对直接引语中的人称、时态、指示代词、时间状语、地点状语等进行改变。
1. 时态的变化:直接引语变为间接引语时,通常受转述动词said, asked等的影响而使用过去化的时态,即把原来的时态向过去推,也就是一般现在时变为一般过去时,现在进行时变为过去进行时,等等。例如:
Tom said to me,“My brother is doing his homework.”
→Tom said to me that his brother was doing his homework.
2. 人称代词、指示代词、时间状语、地点状语等等的变化:根据意义进行相应的变化,例如:
She asked Jack,“Where have you been?”
→She asked Jack where he had been.
He said,“These books are mine.”
→He said that those books were his.
二直接引语改为间接引语时,都使用陈述语序,但是因为原句的句式不同,所以变成间接引语时所用的连词会有所不同。直接引语如果是一般疑问句,用连接词whether或if;如果是特殊疑问句,则用疑问词引导间接引语。转述的动词一般用asked,可以在其后加上一个间接宾语me, him, her, us等。如:
She said,“Is your father at home?”
→She asked me if/whether my father was at home.
“What do you do every Sunday?”My friend asked me.
→My friend asked me what I did every Sunday.
直接引语如果是祈使句,改为间接引语时,要将祈使句的动词原形变为带to的不定式,并在不定式的前面根据原句的语气即请求或命令加上ask, tell, order等动词,如果祈使句为否定式,则在不定式前加not。其句型为:ask / tell / order someone not to do something. 例如:
She said to us,“Please sit down.”
→She asked us to sit down.
He said to him,“Go away!”
→He ordered him to go away.
He said, “Don’t make so much noise, boys.”
→He told the boys not to make so much noise.

1、宾语从句:注意事项
用陈述句的语序。
注意从句的时态呼应(主句是现在时,从句用各种时态;主句是过去时,从句用过去的时态,包括过去、过去进行、过去完成、过去将来),表示客观真理或普遍事实时除外。
主句的谓语动词是advise,demand,request,order,suggest,insist时,宾语从句的谓语动词用should+v.
主句的主语是第一人称,谓语是think,suppose,believe,expect,imagine时,否定转移。
that引导宾语从句时,一般省略。不省略的情况为:a.从句位于句首以示强调时;b.及物动词后的第二个及以后的宾语从句;c.谓语动词和that从句间有短语隔开时;d.在复合宾语中;e.宾语从句由“从句+主句”构成,从句的引导词紧跟在主句谓语动词后,that不省。
词组:right away at once immediately
burst into laughter/tears
burst out doing sth
as if/though
in ruins
injure wound hurt
destroy damage
be trapped in
dig out
bury oneself in doing sth
rise raise arise

地点状语从句
1、地点状语从句由where,wherever引导。
注意:where与where的区别:Where表特定的地点,而wherever表示非特定的地点。
Wherever=to/atanyplacewhere
2、地点状语从句与定语从句的区别
Where引导定语从句时,从句前应有一个表示地点的名词作先行词;而状语从句前则无先行词。
什么是时态
英语语法中的时态(tense)是一种动词形式,不同的时态用以表示不同的时间与方式。它是表示行为、动作、状态在各种时间条件下的动词形式,在英语中有16种时态。
下面就英语中常见的十种基本时态进行阐述,其它的时态都是在这十种时态的基础上结合而成的。
在语法里,时或时态表示行为发生的时间和说话时的关系。一般分为过去式、现在式、将来式,通常也有与表示动作进行或终止的进行式和完成式等体貌一起相连用的情况。
时态连同语气、语态、体貌和人称为动词形式至少可能能够表现出的5种语法特性。
有些语言,没有时态的使用,如分析语的中文,但必要时,仍有时间副词的辅助。也有些语言,如日文,形容词的词形变化能表达出时间上的'资讯,有着类似动词的时态性质。还有些语言,如俄文,一个单词就能表现出时态和体貌。
语法知识点
1.as...as...引导的比较级:
(1)“as +形容词或副词原级+ as+被比较对象”结构。例句:He studies as hard as you.他像你一样学习努力。
(2)在否定句或疑问句中可用not so…as….例句:He can not run so/as fast as you.他没你跑得快。
2.only引导的倒装句型:only +状语(或状语从句)位于句首时,句子部分倒装。
例句:Only by diligence and honesty can one succeed in life.只有勤奋、正直,一个人在生活中才能成功。
注意:但only修饰主语时,不倒装。例句:Only that girl knew how to work out the problem.只有那位女生知道怎样解那道题。
3.wish引导的虚拟语气:wish后面的从句,当表示与事实相反的情况,或表示将来不太可能实现的愿望时,其宾语从句的动词形式为:
(1)表示对现在情况的虚拟:从句动词用过去式或过去进行式表示,be的过去式用were.
I wish I knew the answer to the question.我希望知道这个问题的答案。(可惜不知道。)
(2)表示对过去情况的虚拟:从句动词用had +过去分词。
I wish (that) I hadn’t wasted so much time.我后悔不该浪费这么多时间。(实际上已经浪费掉了。)
(3)表示对将来的主观愿望:谓语动词形式为“would/ should/ could/ might +动词原形”。在这种情况下,主句的主语与从句的主语不能相同,因为主句的主语所期望的从句动作能否实现,取决于从句主语的态度或意愿(非动作名词除外) 。
I wish it would stop raining.但愿雨能停止。
注意:若wish后的宾语从句中用would,可以表示请求,通常意味着说话人的不快或不满。
例句:I wish you would be quiet.我希望你安静一些。
4.it形式宾语:和it作形式主语一样,我们常用it来作形式宾语,把真正的宾语从句放在句末,这种情况尤其出现在带复合宾语的句子中。
例句:He has made it clear that he will not give in.他表明他不会屈服。
5.The+比较级,the+比较级表示“越.....越......"
例句:The more scared we are, the stronger the difficulty will become。我们越害怕困难,困难就会变得越强大。

语法
一、结构:现在完成时被动语态的结构就是现在完成时态和被动语态结构的.叠合,
即"have+been+动词过去分词"。
二、用法:现在完成时被动语态结构常用于以下两种情况:
(1)主谓关系被动,而且谓语动作从过去一直延续到现在;
(2)主谓关系被动,而且谓语动作发生在过去,但已对现在造成影响或结果。
三、现在完成时主动句和被动句之间的转换:如果要将现在完成时的主动句转换成被动句,则要把其宾语变为主语,谓语动词变为被动结构,主语变为由介词引导的状语或直接将其省略;反之,如果要把被动句变为主动句,则恢复其原来的主语,谓语动词套用主动结构。
