状语从句中的时态对应

状语从句中的时态对应

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；

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。

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。

◆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. I will call you as soon as she arrives.

当她来的时候，我就打电话给你。

主从句的时态问题

主从句的时态问题

从句和主句中谓语动词的时态 在复合句中，主句和从句的谓语动词时态一般遵循以下的规律： 一① 在以下三种主语从句中，主语从句的谓语动词要用“should+动词 原形”， should可省略。 (1)It is+形容词+that…句型。常见的形容词有important, necessary, natural, funny, strange, surprising, astonishing(令人惊讶的)等。 (2) It is +名词+that…句型。常见的名词有pity, shame, advice, suggestion, proposal(提议，建议)， requirement, request, desire, order 等。 (3) It is+动词的过去分词+ that…句型。常见的动词有advise, order, propose, request, suggest, demand, require等。 ②在insist(坚持)， urge (催促)， order(命令)， command(命令)，suggest(建议)，advise(建议)，recommend(建议，推荐)， request(请求，要 求)， demand(要求)，require(要求，需要)等动词后的宾语从句中，谓语动词用“should+动词原形”， should可省略。 ③ 在含有advice, order, demand, proposal(提议)， requirement, suggestion等名词的表语从句、同位语从句中，谓语动词用“should+动词原形”，should可省略。 ④在一些表示惊讶、意志等感情色彩的名词性从句中，谓语动词用“should+动词原形”或“should +have done”，译为“竟然，居然”。例如： I am surprised /shocked that you should speak in such a way。 I find it astonishing that he should be so rude to his mum。 It is strange /surprising that she should not have been invited。 I am glad that your story should have won the first prize。

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

状语从句。主谓一致。几种时态转换

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.

初中英语状语从句知识点总结

初中英语状语从句知识点总结(一） 用来修饰主句中的动词，形容词或副词等而充当状语的从句叫做状语从句。状语从句常用从属连词来引导,与主句连接起来。若置于句末,则前面不加逗号。根据意义和作用，状语从句可分为时间原因条件等几种。下面我们就来分析一下这几种状语从句。 1时间状语从句 时间状语从句常用从属连词wheｎ,aｆtｅｒ，unｔil,as soon as，等来引导。 当主句是祈使句或谓语动词是一般将来时态或情态动词时,其时间状语从句中的谓语动词常用一般现在时态表示将来发生的动作或存在的状态。这就是我们常说的“主将从现”。 如:Ｐlease cａll me ｗheｎ yｏu ｇeｔｔｈere．当你到那时,请给我打个电话。 I ｗill write tｏ you ａs ｓｏｏn as I arrｉｖe in Beｉjing.我一到北京就给你写信。 <温馨提示>siｎce引导时间状语从句表示“自从…以来”，从句中的动词一般表示动作的起点，用过去时;而主句的动作延续的情况则用一般现在时或现在完成时。常用的句型为： It hａs beｅn/is+一段时间+ｓｉnｃe+过去时。 如：I hａs ｂeｅｎ/is three yeａrs since ｗe meｔ laｓt ｔｉｍe.自从我们上次见面,已经三年了。 2条件状语从句 引导条件状语从句的连词或词组有：if(如果),unless(除非),as ｌｏnｇ as(只要）等。如果主句是将来时，条件状语从句也用一般现在时来表示。 如：I will ｓtａy at home ｉf it raiｎs tomorrｏｗ.如果明天下雨,我就待在家。 You can’t learn Englisｈweｌl unｌess you woｒk ｈard． 除非你努力学习，否则是学不好英语的。 <温馨提示>由ｉf引导的条件状语从句，若从句表达的是与现在事实相反的事实,则常用虚拟语气,即用过去时态表示(如果涉及到ｂe动词，一律都用wｅre)。此时,主句则用过去将来时。

状语从句的时态特点一般情况下

状语从句的时态特点一般情况下，时间和条件状语从句的谓语动词一般用“一般现在时”表示“一般将来时”，用“现在完成时”表示“将来完成时”。例如： I will call you as soon as I arrive in Beijing. 我一到北京就给你打电话。（这是由as soon as引导的时间状语从句，从句中的谓语动词arrive是一般现在时，表示一般将来时，决不可用will arrive） As soon as I have finished this work, I will go home. 我一完成此工作，就回家。（从句中的谓语动词用现在完成时have finished，表示将来完成时,决不可用will have finished）If he comes back, please let me know.如果他回来了，请通知我。（从句中的谓语动词用comes back,表示一般将来时，决不可用will come back） 状语从句讲解和练习 状语修饰动词、形容词、副词或整个句子。通常由副词、介词短语、动词不定式、分词和从句等担当。例如： 1. Naturally , our grandparents were pleased to get our phone call . (副词) 2. We worked hard , from sunrise to sunset . (介词状短语) 3. To help my disabled aunt , I spend an hour working in her house every day . (不定式) 4. Seen from a distance , the farmhouse looked deserted . (过去分词) 5. I know how to light a camp fire because I had done it before .（原因状语从句） 状语的位置比较灵活，可以位于句首、句末或句中。enough用作状语修饰形容词和副词时必须后置。 状语从句主要用来修饰主句或主句的谓语。一般可分为九大类，分别表示时间、地点、原因、目的、结果、条件、让步、比较和方式。尽管种类较多，但由于状语从句与汉语结构和用法相似，所以理解和掌握它并不难。状语从句的关键是要掌握引导不同状语从句的常用连接词 和特殊的连接词即考点。现分别列举如下: 1．时间状语从句 常用引导词：when, as, while, as soon as, before, after, since , till, until 特殊引导词：the minute, the moment, the second, every time, the day，the instant, immediately , directly, no sooner … than, hardly …when, scarcely … when I didn’t realize how special my mother was until I became an adult. While John was watching TV, his wife was cooking. The children ran away from the orchard(果园) the moment they saw the guard. No sooner had I arrived home than it began to rain. Every time I listen to your advice, I get into trouble. 2．地点状语从句 常用引导词：where 特殊引导词：wherever, anywhere, everywhere Generally, air will be heavily polluted where there are factories. Wherever you go, you should work hard. 3．原因状语从句 常用引导词：because, since, as, for 特殊引导词：seeing that, now that, in that, considering that, given that.

主从句的时态问题

从句和主句中谓语动词的时态 在复合句中，主句和从句的谓语动词时态一般遵循以下的规律： 一① 在以下三种主语从句中，主语从句的谓语动词要用“should+动词 原形”， should可省略。 (1)It is+形容词+that…句型。常见的形容词有important, necessary, natural, funny, strange, surprising, astonishing(令人惊讶的)等。 (2) It is +名词+that…句型。常见的名词有pity, shame, advice, suggestion, proposal(提议，建议)， requirement, request, desire, order 等。 (3) It is+动词的过去分词+ that…句型。常见的动词有advise, order, propose, request, suggest, demand, require等。 ②在insist(坚持)， urge (催促)， order(命令)， command(命令)，suggest(建议)，advise(建议)，recommend(建议，推荐)， request(请求，要 求)， demand(要求)，require(要求，需要)等动词后的宾语从句中，谓语动词用“should+动词原形”， should可省略。 ③ 在含有advice, order, demand, proposal(提议)， requirement, suggestion等名词的表语从句、同位语从句中，谓语动词用“should+动词原形”，should可省略。 ④在一些表示惊讶、意志等感情色彩的名词性从句中，谓语动词用“shou ld+动词原形”或“should +have done”，译为“竟然，居然”。例如： I am surprised /shocked that you should speak i n such a way。 I find it astonishing that he should be so rude to his mum。 It is strange /surprising that she should not have been invited。 I am glad that your story should have won the first prize。
