英语时态的变化规律
1)宾语从句如果主句是一般现在是,则从句按实际情况判断,如果是过去是从句变为相应的过去,比如本来是一般现在变为一般过去,一般将来变为过去将来,现在进行变为过去进行,现在完成变为过去完成,等等
(2)状语从句,特殊的是条件状语从句,主句将来。从句一般现在。其他的时态保持一致。
(3)定语从句,按照具体情况来判断。不受主句限制,
例如,the women (whom you talked with yesterday) is hanmei.括号中的是定语从句
初中主要涉及到这三种。这也只是我自己的总结,你可以在多看写参考书~~~
这还有网上的。
1.主语从句
1)主语从句可直接位于主语的位置,如果从句较长,谓语又较短,可用it作形式主语,而将从句放在句末。常见的句型有:
*It is a fact\a pity\a question\good news that...
*It seems\appears\happened\has turned out that...
*It is clear\important\likely\possible that...
*It is said\reported\estimated\has been proved that...
It is said that comic books create a connection between people of the same generation.
It seems that the performance is very useful.
2)what引导的主语从句表示“...的东西时”,一般不用it作形式主语。
What we lack is experience.
3)what,who,when,why,whether等词含有各自的疑问意义,但它们引导的主语从句,都用陈述语序。
How the plan is to be carried out should be discussed again.
I did know why I felt like crying.
2.宾语从句
1)宾语从句可位于及物动词、介词和某些形容词后。连词that常可省略。介词后一般接疑问词引导的宾语从句。in that(因为),except that(除了),but that(只是)已构成固定搭配,其他介词后一般不接that引导的宾语从句。
*I promised that I would change the situation.
*All this is different from what American young people would say about friendship.
*He is certain that watching so much television is not good for children.
*This article is well-written except that it is a bit too long.
2)宾语从句后如有宾补,要用形式宾语it来代替,而把宾语从句移至宾补之后。
He has made it clear that he would not change his mind.
3)在think,believe,suppose,expect等动词后的宾语从句中,如果谓语是否定的,一般将否定词移至主句谓语上,宾语从句则变成肯定形式。
He didn't think that the money was well spent.
3.表语从句
表语从句出现在结构为“主语+系动词+表语从句”的句子中。表语从句除可用that,what,when,why,whether,how等引导外,还可由because,as if(though)等引导。that常可省略。如主句主语为reason,只能用that引导表语从句,不可用because.
Perhaps the most important thing to remember is that there is no one common type of life in America.
The reason why so many people died there is that there were not enough food supplies.
It looks as if successful international cultural communication will make the world smaller.
4.同位语从句
同位语从句用于对前面出现的名词作进一步说明,一般用连词that引导,由于先行名词的意义不同,也可用whether,who,when,where,what,why,how等引导。常见的先行名词有fact,idea,belief,news,hope,conclusion,evidence,suggestion,order,problem,report,decision.有时由于谓语较短,将同位语从句位于谓语之后。
She finally made the decision that she would join the fashion show.
I had no idea how many books I could borrow at a time.
The news came that their team had won the championship.
5.定语从句
定语从句所修饰的先行词可以是名词或代词,也可以是一个句子。定语从句通常位于先行词之后,由关系代词或关系副词引导。
*限制性定语从句
限制性定语从句修饰先行词,对先行词起修饰作用,紧接先行词之后,无逗号,若省去,原句意思不完整。引导定语从句的关系代词有who,whom,whose,which,that等。who,whom,whose用于指人,whose有时也可指物,相当于of which;which用于指物;that既可指人也可指物,但只用于限制性定语从句中。关系代词除了引导定语从句,替代先行词外,还在从句中担任主语、宾语、定语等。
The computers and cables which make up the Internet are owned by people and organizations.
Those who live alone or who are sick may have trouble in getting close to other people.
The girl whose parents died in an accident is living with her grandmother.
1)当先行词是all,anything,everything,something,nothing等不定代词或先行词前有first,last,any,few,much,some,no,only以及形容词最高级修饰时,只能用关系代词that引导从句。
That is all that I've heard from him.
He's the first person that I'm going to interview this afternoon.
2)关系代词的省略
在从句中作宾语的关系代词常可省略。关系代词紧跟介词,作介词宾语时不可用that,只可用which或whom引导从句,并且不可省略,但当介词位于宾语从句句末时,作为介词宾语的关系代词仍可用that,也可省略。
This is one of those things with which we have to put up.
This is one of those things (which\that) we have to put up with.
3)引导定语从句的关系副词有when,where,why等。关系副词在从句中作状语,意义上相当于一个“介词+which”的结构。
Even in comic books where(=in which) there are no words,the stories are fully expressed through the drawings.
No one knows the reason why(=for which) he was so angry that day.
5.定语从句
*非限制性定语从句
非限制性定语从句既可修饰先行词,也可修饰整个主句,起补充说明作用,与主句之间有逗号隔开,若省去,原句意思不受影响。不可用that引导非限制性定语从句。关系词不可省略。
Every object has a gravitational pull,which is rather like magnetism.
*“介词+which\whom\whose”引导的定语从句
“介词+which\whom\whose”可引导限制性定语从句,也可引导非限制性定语从句,该结构中介词的选择取决于从句谓语动词的固定搭配,或先行词的习惯搭配。
This is the computer on which he spent all his savings
It is written by a person with whom we are all familiar.
*as引导的定语从句
as引导的定语从句主要用于“such...as”及“the same...as”的结构中,代替先行词是人或物的名词。as引导非限制性定语从句时,代替整个主句,从句可位于主句之前、之后或中间。
These are not such problems as can be easily solved.(as代替先行词problems)
As is mentioned above,no single company or group can control what happens on the Internet.(as代替主语)
6.状语从句
*时间状语从句
引导时间状语从句的从属连词和词组有:
1)when,whenever,while,as,after,before,since,till,until,once等。
We have learnt quite a lot about it since we came here.
2)as soon as,hardly(scarcely)...when,no sooner...than,each(every) time,the moment,immediately(that)等。
As soon as I sent an e-mail message,I received positive responses.
The moment he heard the good news,he jumped with joy.
*地点状语从句
引导地点状语从句的连词是where,wherever.
Wherever she went,she took her little daughter with her.
*原因、结果和目的状语从句
1)引导原因状语从句的从属连词有:because,as,since,now(that),seeing that,considering that,in that等。
Considering that he is a freshman,we must say he is doing well.
2)引导结果状语从句的连词有:so...that,such...that
,so that,that,so等。
Mickey Mouse is so attractive that the children are reluctant to leave.
3)引导目的状语从句的连词有:so that,in order that,for fear that,lest等,从句常使用may,might,can,could,would等情态动词。
We got up early this morning so that we could catch the first bus to the railway station.
*条件和让步状语从句
1)引导条件状语从句的连词和词组有if,unless,as(so) long as,on condition that,in case,provided(providing) that,supposing等。
As long as you have the right equipment,you can use a telephone line to transmit computer data.
2)引导让步状语从句的连词和词组有though,although,whether,even though,even if,no matter what(when,how...),whatever(whenever,wherever,however....)等。though,even if等引导状语从句可转换成含有as的部分倒装结构,具有强调意义。其结构为“形容词(副词、动词、名词)+as+主语+谓语”。
No matter what you may say,I would not change my mind.
Young as he is,he is quite experienced in this work.(=though he is young)
Child as he is,he can speak English fluently.(=though he is a child)
*方式状语从句
引导方式状语从句的连词有as,just as,as if,as though等。as if,as though引导的状语从句中,谓语动词常用虚拟语气,表示与事实相反。
The young man made the experiment just as the teacher had taught him.
Everything went on as usual as if nothing had happened.

英语中的6个时态 要详细的构造组成以及动词变化规则
动词时态
英语有很多动词时态,全部这些都只是表明动作发生的时间;不过同大多数日耳曼语一样,这些时态最终可以划为四种:现在和过去的直陈与虚拟.使用“to be”和“to have”,再加上现在分词和过去分词,就可以创造岀各种复合时态.英语中有12个主要时态,都来自于三时(过去、现在、将来)和四体(一般、进行[或未完成]、完成、完成进行)的交叉组合.(在被动语态中,有一些组合会极少岀现,尤其是“将来完成进行时”.)下方是一些主要英语动词时态的例子.
主动词根据人称变化的时态:
一般现在时:
“I listen.”对很多动词来讲,这个时态用来阐述习惯或能力.
助动词根据人称变化的时态:
现在进行时:
“I am listening.”表达现在正在进行的动作.要表达这个意思,在英语中需要用到现在进行时,但在其他大多数语言中只用一般现在时就可以.请注意,这种形式在英语中也可以表达将来时,比如“We're going to the movies tonight”.
过去进行时:
“I was listening.”表达在过去某时刻持续进行的动作.
现在完成时:
“I have listened.”通常表达一个动作在过去某一时刻发生了,动作已结束.
现在完成进行时:
“I have been listening.”表达一个动作在过去某一时刻发生,并一直延续到现在.
一般将来时:
“I shall listen”或“I will listen.”表达一个动作会在将来发生,或说话人表示要完成某个行动.3
将来进行时:
“I shall be listening.”表达将来的某个持续进行的动作,此动作现在还没有开始.(使用will可以表达主观愿望.3)
主动词和助动词都不根据人称变化的时态:
不定式:
“to listen”与其他动词连用,如“I was to listen to the story”.
一般过去时:
“I listened.”在英语中表达某个动作在过去发生,而不是现在(不同于其他一些语言中的不定过去时).
过去完成时:
“I had listened.”表达某个过去的动作在过去某一时刻之前已经完成.
过去完成进行时:
“I had been listening.”表达一个动作在过去某一时刻发生,并一直延续到过去另一个时刻.
将来完成时:
“I shall have listened.”表达一个动作会在将来某一时刻之前完成.
将来完成进行时:
“I shall have been listening.”表达一个动作会在将来某一时刻开始,并一直延续到将来另一时刻.
