名词性从句、定语从句、状语从句时态问题
一、名词性从句
（一）在宾语从句中主句和从句之间的时态的一致关系,通常由主句谓语的时态决定从句谓语的时态.
⒈若主句谓语动词是现在时或将来时,如：一般现在时,现在完成时,一般将来时,将来完成时等,从句可以根据需要使用任何时态.
如:He says that he is doing well in his lessons.you will miss a lot of lessons.the boy is lazy.XiaoWang was late for school yesterday.Jim has been back for two days.
⒉若主句谓语动词是过去时态(一般过去时,过去进行时,过去完成时,过去将来时,过去将来完成时),从句谓语动词也必须是过去时态.
如:He said he enjoyed himself last Sunday.he hadn’t bought any present.the would come back the next day.he was doing his homework·
⒊当从句表示客观事物或真理,或人们已经公认的道理时,其时态不受主句谓语动词的时态的影响.即使主句谓语动词使用了过去时的某种时态,从句的时态仍然是现在的某种时态.
1)The teacher said the earth goes around the sun。
2)He said the sun rises in the east.
3)His father said he gets up at six o'clock every morning.
4)He told me the light travels faster than the sound.
⒋当从句表示并未出现或尚未实现的愿望时,必须用过去时态.
⒌（可包含在1/2中）有些形容词后面可跟有从句,这种从句一般可看作宾语从句,其谓语也应与主句谓语的时态保持一致.可跟这种宾语从句的形容词有：afraid,glad,sure,confident,sorry, certain,conscious,aware等.一致的原则与宾语从句相同.
例如：
I'm confident that I'll pass the exam.我有信心通过考试.
He was lucky that he wasn't killed.他很幸运没有被杀死.
（二）在主语从句,表语从句和同位语从句中,主句和从句之间的时态一致关系所遵守的法则和宾语从句相同.
例如：
It appears that some little trouble was caused by a woman,whose name has not been ascertained.看来这件小小的麻烦是由一个至今尚不清楚其姓名的女人所引起的.
It was known long ago that Professor Einstein played a key role in the development of the theory of relativity.人们早已知道,爱因斯坦教授对相对论的发展起了关键作用.
It was proved centuries ago that the speed of light is186,000miles a second.几世纪前就证实了光的速度为每秒186,000英里.
The fact[that man would soon be able to visit the moon]built up new scientific interest in earth's nearest neighbor.人类不久可以游览月球的事实,引起了对地球最近邻居的新的科学兴趣.二、定语从句与主句的时态一致关系
定语从句的时态不受影响意思就是定语从句的时态是根据事物真实发生的情景决定不受主句影响,因为定语从句的作用只是在修饰句子中的名词之类的,和句子本身的时态没有关系.比如：
He is a man whose telephone was stolen.他是那个手机被偷的那个人.
主句一般现在时,从句过去时,因为手机真实被偷是在过去发生.
I went to the apartment in which Mary lives in.我去过Mary现在住的房子.
主句过去式,从句一般现在时,因为我去过的那个房子,Mary确实现在在住.
⒈若定语从句的谓语表示的动作和主句谓语表示的动作同时发生,则要求使用同样的时
态.
The original manuscript of"The Theory of Relativity"was written by Einstein who
was employee in a patent office.“相对论”的原稿是由当时在一家专利办公室工作的爱因斯坦写的.
⒉主句与定语从句的谓语表示的动作如果不是同时发生,时态则不要求一致.
例如：
Have you seen the new golf clubs that Mr.Stevens gave Bill?你看过史蒂文斯先生给比尔的那些新高尔夫球棒了吗?
I painted several pictures that are now on show in the museums.我画了几张画,现在正在博物馆里展出.
三、状语从句与主句的时态
状语从句中的时态对应类型。（同名词性从句）
1、主句谓语动词为现在时态，则从句动词可根据需要使用任何时态；
Each of the major glacial stages produces distinctive land forms that remain long after the glacier has disappeared.
每一主要冰河期都产生特殊的地形,这种地形一直保留到冰川消失之后很久.
2、主句谓语动词为过去时态，从句的时态一般是过去范畴的时态，其中有如下几种情况要注意：
（1）当从句的动作与主句的动作同时发生，从句中一般用一般过去时或过去进行时。e.g.
When Abraham Lincoln became President of the United States of America,he was completely involved in the problem of slavery.当亚伯拉罕·林肯成为美国总统时,他便陷入到奴隶问题的漩涡中去了.
The children ran away from the orchard(果园)the moment they saw the guard.
（2）从句的动作发生在主句动作之后，从句时态用过去将来时。
（3）从句的动作发生在主句动作之前，从句时态用过去完成时。
After she had finished her work,she hurried to the nursery to pick up her child.
干完工作后,她匆匆赶到托儿所接孩子.
The director had explained the details many times before the workers took the job.
工头在工人们开始工作前把细节给他们讲了好多遍.
3、状语从句中特殊的时态关系（真是条件状语从句、非真实条件状语从句）。
◆主将从现原则◆
在if，unless等词引导的条件状语从句；
在when，till/until，as soon as，before，after，as，while，each time，the moment等词引导的时间状语从句；
在no matter+wh-，however，whatever，whenever，even if/even though，so long as，on condition that等引导的让步状语从句中，若主句为一般将来时（或包含情态动词/祈使句），从句谓语动词常用一般现在时表示将来；若主句为过去将来时，从句谓语动词通常用一般过去时态代替过去将来时态。
e.g.
新概念例句：
If you park you car in the wrong place,a traffic policeman will soon find it.
I will call you as soon as she arrives.当她来的时候，我就打电话给你。
If it clears up,we will go to the park.如果天晴的话，我们就去公园。
I will not let them in,whoever they are.不管他们是谁，我都不会让他们进来。
If their marketing plans succeed,they____their sales by20percent.
A.will increase
B.have been increasing
C.have increased
D.would be increasing
◆特定引导词及句式的时态◆
Ⅰ.since
since引导的时间状语从句为一般过去时，主句中的时态用现在完成时或现在完成进行时。
e.g.

I have been learning English since I was in Grade3.自从上三年级以来，我一直在学英语。The girl told her father she had been ill since she came home.那个女孩告诉她父亲，自从回到家她就一直在生病。
Note:It+be+一段时间+since…中，若主句为一般现在时或现在完成时，从句常用一般过去时；如果主句为一般过去时，从句则常用过去完成时。
e.g.
It is more than three years now since I saw her last.从我上次见到她我们已有三年多没见面了。It has been three years since I was in Beijing.我不在北京已经三年了。(1988全国)
They asked me to have a drink with them.I said that it was at least ten years since I____a good drink. A.had enjoyed B.was enjoying C.enjoyed D.had been enjoying Ⅱ.before

A.before
B.since
C.till
D.after
Ⅲ.by the time
by the time指到某一点时间为止，主句常用完成时态。一般情况下，如果从句表示的是过去时间，主句常用过去完成时；如果从句表示的是将来时间，主句则常用将来完成时。e.g.

真实条件状语从句与非真实条件状语从句的三个不同
if既可引导一个真实条件状语从句又可引导一个非真实条件状语从句，二者主要在以下三个方面有所不同：
一、意义及谓语动词形式不同
如果该条件纯属假设，谓语动词用虚拟语气，有可能实现的条件则使用动词通常的陈述形式：
非真实条件状语从句（非真实过去）的谓语动词，用动词过去式来表示与现在事实相反或难以实现的愿望，主句则用/"would+动词原形/"；
而真实条件状语从句的谓语动词，用动词的一般现在时表示一般或未来情形下的条件，主
试比较：
If my husband were a woman,he would understand my feelings a bit better.如果我丈夫是个女人的话，他就会更好一点儿理解我的感情了。(丈夫不可能是女人)
Oil floats if you pour it on water.如果你把油倒在水上，它就漂浮在上面。（能实现的事实）非真实条件状语从句的谓语动词用/"had+过去分词/"表示与过去的事实相反，主句用/"would have done/"；
真实条件状语从句用一般过去时指过去的事实或用于间接引语中（可表示过去将来的情况），主句用一般过去时或过去将来时。
If I had been a teacher at that time,I would have argued with him.当时我要是老师的话，就和他争辩了。（事实上当时不是老师）
If Mike was a liar,it was for my sake.如果麦克曾经是个撒谎的人，那也是为了我。（当时麦克极有可能是撒了谎）
He said he would go there if it was fine the next day.他说，如果第二天天气好他就去那里。二、从句所接的情态动词的含义不同
1．if I(we,you,he...)+/"should+动词原形/"或/"were to+动词原形/"或动词过去式，表示对将来情况的虚拟假设，即某事不会或不太可能发生，具有较大的试探性。如：
If you should run into Peter,please tell him he owes me a letter.假如你碰见皮特，告诉他他该给我写信了。
What would you do if war were to break out?如果战争爆发，你会怎么办？
2．if引导的真实条件状语从句一般很少使用将来时态，但有时也可用情态动词will或would 来表示/"愿望/"（如果......愿意......），甚至可用这种方式提出请求。如：
It/'ll make me very happy if you/'ll accept it.如果你愿意收下它我会很高兴的。
If you will wait a moment,I/'ll go and tell the manager that you are here.如果你愿意等一会儿，我就会去告诉经理你来了。
If you will hold my bag,I/'ll open the door(i.e.please hold my bag).如果你愿意替我拿包，我就开门（即，请替我拿包）。
三、与其他句型的转换不同
1．非真实条件状语从句中的if可省略，从句可以用倒装语序；而真实条件状语从句一般不可以。如：
If he were my son,I would beat him.如果他是我的儿子我就打他。→Were he my son,I would beat him.(√)
If you touch me again,I/'ll call the police.你再碰我，我就叫警察。→Do you touch me again,I/'ll call the police.(×)
2.真实条件状语从句可以转换为/"祈使句+and+陈述句/"，而非真实条件状语从句则不可以。如：
If you touch me again,I/'ll call the police.→(You)Touch me again and I/'ll call the police.(√)
3.真实条件状语从句的否定式可与unless...转换，而非真实条件状语从句的否定式却不能。如：
If it doesn/'t rain tomorrow,I/'ll plant the flowers.如果明天不下雨，我就把花栽上。→I/'ll plant the flowers unless it rains tomorrow.(√)
If it hadn/'t been for you,I would have failed in the exam.如果不是你的话我就不会通过考试了。→Unless it had been for you,I would have failed in the exam.(×)

名词性从句、定语从句、状语从句时态问题
一、名词性从句 （一）在宾语从句中主句和从句之间的时态的一致关系,通常由主句谓语的时态决定从句谓语的时态. ⒈若主句谓语动词是现在时或将来时,如：一般现在时,现在完成时,一般将来时,将来完成时等,从句可以根据需要使用任何时态. 如:He says that he is doing well in his lessons.you will miss a lot of lessons.the boy is lazy.XiaoWang was late for school yesterday.Jim has been back for two days. ⒉若主句谓语动词是过去时态(一般过去时,过去进行时,过去完成时,过去将来时,过去将来完成时),从句谓语动词也必须是过去时态. 如:He said he enjoyed himself last Sunday.he hadn’t bought any present.the would come back the next day.he was doing his homework· ⒊当从句表示客观事物或真理,或人们已经公认的道理时,其时态不受主句谓语动词的时态的影响.即使主句谓语动词使用了过去时的某种时态,从句的时态仍然是现在的某种时态. 1)The teacher said the earth goes around the sun。 2)He said the sun rises in the east. 3)His father said he gets up at six o'clock every morning. 4)He told me the light travels faster than the sound. ⒋当从句表示并未出现或尚未实现的愿望时,必须用过去时态. ⒌（可包含在1/2中）有些形容词后面可跟有从句,这种从句一般可看作宾语从句,其谓语也应与主句谓语的时态保持一致.可跟这种宾语从句的形容词有：afraid,glad,sure,confident,sorry, certain,conscious,aware等.一致的原则与宾语从句相同. 例如： I'm confident that I'll pass the exam.我有信心通过考试. He was lucky that he wasn't killed.他很幸运没有被杀死. （二）在主语从句,表语从句和同位语从句中,主句和从句之间的时态一致关系所遵守的法则和宾语从句相同. 例如： It appears that some little trouble was caused by a woman,whose name has not been ascertained.看来这件小小的麻烦是由一个至今尚不清楚其姓名的女人所引起的. It was known long ago that Professor Einstein played a key role in the development of the theory of relativity.人们早已知道,爱因斯坦教授对相对论的发展起了关键作用. It was proved centuries ago that the speed of light is186,000miles a second.几世纪前就证实了光的速度为每秒186,000英里. The fact[that man would soon be able to visit the moon]built up new scientific interest in earth's nearest neighbor.人类不久可以游览月球的事实,引起了对地球最近邻居的新的科学兴趣.二、定语从句与主句的时态一致关系 定语从句的时态不受影响意思就是定语从句的时态是根据事物真实发生的情景决定不受主句影响,因为定语从句的作用只是在修饰句子中的名词之类的,和句子本身的时态没有关系.比如： He is a man whose telephone was stolen.他是那个手机被偷的那个人. 主句一般现在时,从句过去时,因为手机真实被偷是在过去发生. I went to the apartment in which Mary lives in.我去过Mary现在住的房子. 主句过去式,从句一般现在时,因为我去过的那个房子,Mary确实现在在住. ⒈若定语从句的谓语表示的动作和主句谓语表示的动作同时发生,则要求使用同样的时

名词性从句精讲(讲解+练习)
名词性从句精讲 在句子中起名词作用的句子叫名词从句(Noun Clauses）。名词从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语等，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。That he will come h ere surprises me. I know that he will come here. The news is that he will come here.The new that he will come here surprises me. 一、名词性从句的相同点：1.结构 2.连接词 引导名词性从句的连接词可分为三类： 从属连接：that, whether, if（不充当从句的任何成分） 连接代词：what, whatever, who, whoever, whom, whose, which. 连接副词：when, where, how, why 二、四大名词性从句的剖析 1.主语从句 作句子主语的从句叫主语从句。主语从句通常由从属连词that，whether，if和连接代词what，who，which，whatever，whoever以及连接副词how，when，where，why等词引导。that 在句中无词义，只起连接作用；连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用，在从句中充当从句的成分。例如： That he suddenly fell ill last week made us surprised. 上星期他突然生病了让我们很惊讶。 Whether he will be able to come remains a question.他是否能够来仍然是一个问题。What he wants to tell us is not clear. 他要跟我们说什么，还不清楚。Where the English evening will be held has not yet been announced.英语晚会将在哪里举行，还没有宣布。 有时为避免句子头重脚轻，常用形式主语it代替主语从句作形式主语放于句首，而把主语从句置于句末。主语从句后的谓语动词一般用单数形式。常用句型如下： （1）It + be +形容词+主语从句It is very interesting that he likes such kind of books. （2）It + be +名词+主语从句It is a pity that he missed the lecture. （3）It + be +动词的过去分词+ that从句It is said that they have won the game. （4）It +不及物动词+ that从句It seems that something is wrong with the computer. 另注意在主语从句中用来表示必须、理应如此、建议、要求等语气时，谓语动词要用虚拟语气“(should) +do”，常用的句型有： It is necessary (important, natural, strange, etc.) that … It is suggested (requested, proposed, desired, etc.) that… 2.宾语从句 名词性从句用作宾语叫宾语从句，在句中可以作谓语动词或介词的宾语。引导宾语从句的连接词与

中考英语语法：状语从句时态类型 1、时态说明 1）在时间和条件状语从句中，通常要用一般现在时表示将来意义，不能直接使用将来时态： I won’t go if it rains tomorrow. 要是明天下雨，我就不去。(不能用will rain) 2）有时也可见到if you will 这样的说法，但那不是将来时态，而是表示意愿或委婉的请求(此时的will是情态动词)： If you will wait a moment, I’ll fetch the money. 请等一下，我就去拿钱。 2、常见类型 状语从句即指在主从复合句中用作状语的从句。状语从句根据其用途可分为时间状语从句、地点状语从句、原因状语从句、结果状语从句、目的状语从句、条件状语从句、方式状语从句等： He was angry because I was late. 他很生气因为我迟到了。(原因状语从句) He was so angry that he couldn’t speak. 他气得话都说不出来。(结果状语从句) Although he is poor, he’s happy. 虽然穷，但他仍很快乐。(让步状语从句) Put it where you can reach it. 把它放在你可以拿到的地方。(地点状语从句) Speak clearly so that they may understand you. 讲清楚些，以便他们能理解你。(目的状从) 中考英语语法复习：主谓语法一致的原则 谓语受主语支配，须和主语在人称和数上保持一致，这叫做主谓一致。主谓一致一般遵循三条原则：语法一致原则，意义一致原则和就近一致原则。 1. 语法一致的原则 （1）以单数名词或代词，动词不定式短语作主语时，谓语动词要用单数;主语为复数时，谓语用复数，例如： He goes to school early every morning. The children are playing outside. To work hard is necessary for a student. （2）由and或both……and连接的并列成分作主语时，谓语动词用复数。例如：Both he and I are right. Mr Black and Mrs Black have a son called Tom. 但并列主语如果指的是同一人，同一事物或同一概念，谓语动词用单数。例如： His teacher and friend is a beautiful girl. The poet and writer has come. （3）由and连接的并列单数主语之前如果分别由each, every修饰时，其谓语动词要用单数形式。例如： In our country every boy and every girl has the right to receive education. Each man and each woman is asked to help. （4）主语是单数时，尽管后面跟有but ,except, besides, with 等介词短语，谓语动词仍用单数。例如： The teacher with his students is going to visit the museum. Nobody but two boys was late for class. Bread and butter is a daily food in the west. （5）一些只有复数形式的名词，如people, police, cattle, clothes等作主语时，谓语动词要用复数。例如： A lot of people are dancing outside.

高中名词性从句教案
高考热点语法教案--名词性从句 知识要点： 1、熟悉并掌握各个连接词、关系代词和连接副词的用法。 2、熟悉并掌握复合句即名词性从句（主语从句、宾语从句、表语从句、同位语从句），定语从句和状语从句。 什么叫复合句 由一个主句和一个或一个以上的从句构成的句子叫复合句。在复合句中主句是全句的主体，从句是全句的一个成分，不能独立。 从句通常是用关联词来引导的。在这里关联词还起联系从句和主句的作用。 主从复合句（Complex Sentences） 一、从句的种类： 注：以it作形式主语，把主语从句后置的常用的句型有： （1）It + be + 形容词+ that从句 （2）It + be + 名词词组+ that从句 （3）It + be + 过去分词+ that从句 （4）It seem, happen等不及物动词+ that从句 二、常用的关联词
1、主语从句： 2、宾语从句：
3、表语从句：
4、同位语从句： 名词性从句包括四种从句即主语从句、表词从句、宾语从句和同位词从句。名词性从句的特点：that 、who、whom、what 、whether及when、where引导名词性从句时必须是陈述句词序： 1、主词从句： That light travels in straight line is known to all . (That 引导主语从句不可省） When the plan is to take off hasn’t been announced ． 主语从句通常以it 做形主语出现
It was my fault that I had him play football all afternoon. It is important that we should go to the school to talk with the teacher. 2、表语从句，即名词性从句放在表语位置就是表语从句，需要注意的，主语 是reason时，表语要用that引导而不是because． The reason why he was late was that he missed the train by one minute this morning . 3、宾语从句that 常可以省略，并且注意时态呼应，当主句为过去时时，从句 时态一定往前推移，不可出现现在时或现在完成时。 The teacher told us that Tomo had left us for America． 4、同位语从句注意与定语从句区别，同位语从句对前一名词做补充说明，在 从句中无语法位置，而定语从句所修饰词在从句中占一语法位置如： The idea that one can do the work without thinking is wrong．( 同位idea在从句中 无位置，而从句只是具体说明idea的内容）。 The idea that you put forward at the meeting is wrong ．(定语从句，idea做put forward 的宾语)。 【专项训练】 1．I wonder how much ． A．cost these shoes B．do these shoes cost C．these shoes cost D．are these shoes cost 2．Nobody knew ． A．where he comes B．where he was from C．where he is from D．where does he come from 3．Excuse me ,would you please tell me ． A．when the sports meet will be taken place ． B．when was the sports meet going to be held． C．when is the sports meet to begin ． D．when the sports meet is to take place ． 4．Computers can only give out has been stored in them . A．that B．which C．what D．anything 5．She wanted to know ．
状语从句的时态特点
1. “主将从现”原则 即若主句为一般将来时，时间和条件状语从句通常要用一般现在时表示将来，而不能直接使用将来时态。如： I’ll give her the telex when she comes. 她来时把电传交给她。 I’ll return the book as soon as I have read it. 这书一看完我就送还。 He’ll have four years at university after he leaves school. 他中学毕业后要上四年大学。 2. since与完成时 since 引导时间状语从句时，其主句通常要用现在完成时，有时也用现在完成进行时。如： She has had another baby since I saw her last. 从上次我见到她以来，她又生了一个孩子。 He has grown an inch since I saw him. 我上次见到他以后他已长高了一英寸。 注：当主句为“It + be + 一段时间”时，则通常用一般现在时代替现在完成时。如：It’s more than three years now since I sa w her last. 我们已有三年多没见面了。 3. 特定句式的时态 由no sooner. . . than, hardly [scarcely]…when引出的时间状语从句，其主句通常用过去完成时，从句通常用一般过去时。如： Hardly had he arrived when she started complaining. 他刚到她就抱怨起来。 No sooner had he gone to sleep than the telephone rang. 他刚睡着电话铃就响了。 We had no sooner set out than a thunderstorm broke. 我们刚出发就下起一阵雷暴。 No sooner had she agreed to marry him than she started to have terrible dou bts. 她刚同意嫁给他她就开始产生可怕的疑虑。

A．because B．if C．although D．after 【答案】C 【解析】 【详解】 句意：许多大学生去中国西部帮助当地人，尽管他们可能在大城市找到一份好工作。A. because因为；B. if如果；C. although尽管；D. after在……之后。句子Many college students go to West China to help local people和句子they may find a good job in big cities.之间存在着转折关系，因此选择although尽管；故选C。 2．---Would you like to go bike riding with us tomorrow? ---Sure, ____ I am busy. A．since B．unless C．when D．until 【答案】B 【解析】 试题分析：句意：----你想要明天和我们一起去划船吗？好的，如果我不忙我就去。A自从；B如果不；C当……时候；D直到……才。根据句意，应选B。 考点：考查连词。 3．—Tom wants to know if you ___ a picnic next Sunday. —Yes. But if it ___， we'll visit the museum instead. A．will have; will rain B．have; rains C．have; will rain D．will have; rains 【答案】D 【解析】 试题分析：句意：汤姆想知道下周你是否要去野餐。——是的，但是如果下雨，我们就会去参观博物馆。结合语境可知上文是宾语从句，描述的是将来发生的动作，故用一般将来时态。下文是条件状语从句，当主句为一般将来时态时，条件状语从句中用一般现在时态表示将来的动作，结合语境可知选D。 考点：从句中的时态 点评：英语宾语从句的时态和主句没有必然的联系，需结合语境进行具体分析。而英语状语从句的时态与主句有比较紧密的联系，若主句为一般将来时，时间和条件状语从句通常要用一般现在时表示将来，而不能直接使用将来时态。 4．Pandas are facing danger!The situation won’t change humans stop killing. A．unless B．though C．if D．after 【答案】A
