【初中英语】初中英语语法大全之状语从句时态类型
【—之状语从句时态类型】下面是老师为同学们带来的对状语从句的时态说明及常态类型,供同学们参考。
1、时态说明
1)在时间和条件状语从句中,通常必须用通常现在时则表示将来意义,而无法轻易采用将来时态:
iwon’tgoifitrainstomorrow.要是明天下雨,我就不去。
(不能用willrain)
2)有时也可以看见ifyouwill这样的观点,但那不是将来时态,而是则表示意愿或直截了当的命令(此时的will就是情态动词):
ifyouwillwaitamoment,i’llfetchthemoney.请等一下,我就去拿钱。
2、常用类型

初中英语主句从句时态关系例句
初中英语主句从句时态关系例句宾语从句中,从句谓语动词的时态要与主句谓语动词的时态相呼应,主要体现在三个方面:1.主句的谓语动词是一般将来时、一般现在时或主句是祈使句时,从句的谓语动词根据实际情况选用具体的时态。
例如:It’s reported that Nanjing South Railway Station at the end of this month. (2011南京)A.has been completedB.is completedC.was completedD.will be completed此题中,从句的时间状语表示将来at the end of this month,主句又为现在时,故从句用将来时。
2.主句的谓语动词是一般过去时,从句的时态要相应地使用与过去相对应的时态,即一般将来时与过去将来时,一般现在时与一般过去时,现在完成时与过去完成时相对应。
例如:The woman asked the policeman where__.(2011重庆)A.the post officeB.the post office wasC.is the post officeD.was the post office 这道考题中,主句动词时态用了过去时,故从句应由原来的一般现在时改为一般过去时。
另外,有必要注意两个特殊的词would和could,它们常出现在中考题中。
would和could 经常用于表示客气、委婉的语气,不表示过去,从句时态应根据实际情况而定。
例如:(1)—Excuse me,I want to go to the 21st National BookExpo(展览会).Could you tell me__?—Sure.It is at No.3 Changjiang Road in Harbin.(2011哈尔滨)A.where it isB.where it wasC.where is it(2)—Would you please tell me__?—At 10:00 this evening.(2010福建晋江)A.when will the train leaveB.when the train will leaveC.when does the train leave3.如果从句反映的是科学事实、客观真理、名言警句时,时态一律都是一般现在时,不管主句用什么时态。

初中英语重点语法三大从句总结初中英语中,主要有三大从句,即宾语从句、定语从句、状语从句(包括时间、条件、结果、目的、原因、让步、地点、方式等)。
1宾语从句在句子中起宾语作用的从句叫做宾语从句。
that: I think that you can pass the exam. Whether/if: I don’t know what the word means. “Wh”: I don’t know what the word means.I don’t know where he found the book.只用whether的情况:1. 与or not连用:I don’t know whether it’s raining or not.2. 与动词不定式连用:He doesn’t know whether to accept the invitation.3. 连接词前有介词时:It depends on whether he is coming.1. 主句是一般现在时态,从句根据实际情况而定(各种时态均可)She wants to know what he has done for the exam.2.主句是一般过去时态,从句用相应的过去的时态。
1)She said that she was a student.2)She said that she would fly to Japan in a week. 3)She said that she had finished her homework already.3. 如果宾语从句说的是客观真理、自然现象或事实时,这时宾语从句要用一般现在时态。
The teacher said that the earth goes round the sun.2定语从句在复合句中修饰名词、代词的从句叫定语从句。
先行词指人 who /that先行词指物 which/ that定语从句一般紧跟被修饰的名词或代词(即先行词)后关系代词代替先行词在句子中担当成分,所以从句中不可再出现其他代替先行词的代词Whom: 先行词指人,则代替先行词在定语从句中充当宾语(包括介词的宾语), 与who的区别是如果前面带介词则必须用whom1. This is the teacher whomwho we like best.2. I don’t like the boy to whom you are talking.Whose :指人或物,作定语,表示“…的”eg: Harry is the boy whose mother is our math teacher.关系代词只能 that 的特殊情况:1.先行词前有序数词修饰时:This is the first gift that my parents bought me.2.先行词前有形容词最高级修饰时:This is the most exciting film that I have ever seen.3. 先行词是不定代词something, anything等时.e.g. Is there anything that you want i n this shop4. 先行词是人和物时, 用that.e.g.He talked about some writers and books that were unknown to us all.5. 先行词被all , little , the only , the very(就是,正是), the last 等词修饰时,只能用thate.g. This is the last place that I want to visit.6. 特殊疑问句以who 或which 开头,只能用that引导.Who is the girl that is making a speech on the platform?当关系代词前使用介词时:物+介词+which ; 人+ 介词 + whom当关系代词前使用介词时:e.g. 1. This is the train by which we went to Beijing.2. This is the teacher to whom my mother is talking.3状语从句在复合句中由从句表示的状语称作状语从句,它可以用来修饰谓语(包括非谓语动词)、定语或状语,或是整个句子。
初中英语复合句中主、从句的时态问题
1一般过去时went2一般现在时go/ goes3一般将来时will go4过去进行时was/were going5现在进行时is /am /are going6过去完成时had gone7现在完成时have/has gone很多同学对英语复合句中的主、从句时态的一致性问题搞不清楚。
今天,我们就来谈谈这个问题。
相信同学们看了这篇文章之后,再遇到复合句中的主、从句的时态问题,就不会感到困难了。
主从复合句中时态的一致主要有以下几种情况:1.主句用一般现在时,从句可用任意时态。
2.主句用过去时,从句用过去某个时态。
3.主句用过去时,从句是客观真理时,只用一般现在时一、在以when,after,as soon as等引导的时间状语从句以及以if,unless 等引导的条件状语从句中,如果主句是一般将来时,从句则用一般现在时。
例如:二、在含有宾语从句的主从复合句中,当主句的谓语动词为过去时态时,从句须用表示过去的某种时态。
例如:He asked when they would go to the party.他问他们什么时候将去参加聚会。
Miss Green said she had been to Beijing before.格林小姐说她以前曾经去过北京。
三、在宾语从句中,当主句的时态为一般现在时、现在进行时、现在完成时等时态时,后面从句时态不受主句限制,可根据情况,选用各种适合的时态。
例如:Do you know when we'll have a football match?你知道我们什么时候举行足球赛吗?You know he has gone to Shanghai.你知道他已去上海了。
四、当宾语从句表述的是客观事实、科学真理、现在的习惯动作以及格言等时,其时态不受主句限制,而用一般现在时。
例如:The teacher told us that light travels faster than sound.老师告诉我们光速比音速要快。

初中英语--条件状语从句的时态有哪些,时间状语从句的引导词用法
条件状语从句的时态有哪些,时间状语从句的引导词用法由引导词if或unless引导的状语从句叫做条件状语从句。
在英文中,条件是指某一件事情实现之后(状语从句中的动作),其它事情(主句中的动作)才能发生,通常译作“假如”。
条件状语从句的时态1 关于条件句有一条语法规则:条件状语从句中通常不用将来时或过去将来时,而用相应的现在时或过去时代替。
然后只要不违背逻辑,条件从句和主句可以根据需要任何可能的时态,因为从句和主句可以是同一个时间,也可以是不同的时间。
2 这个句子中从句和主句都是过去形式,有两种可能:1)虚拟语气,表示与现在或将来事实相反的假设(即实际并没有人要求你解释。
) 2)陈述语气,表示对过去一种可能出现的情况的假设。
根据主句和从句表示的内容来看,虚拟语气的可能性更大一些。
译文:如果连最简单的步骤你都得解释,你会很郁闷的。
(实际你不必对此做解释。
)时间状语从句的引导词用法引导条件状语从句的连词主要有if, unless, as [so] long as, in case 等。
如:If he gets any worse, we must phone for an ambulance. 要是他情况恶化,我们就得打电话叫救护车了。
Unless there is any other business, we can end the meeting. 如果没有别的事情,我们的会议可以结束了。
As long as you’ve paid in advance we won’t charge you for delivery. 只要你预先付款,我们就不收你送货费。
If case I forget, please remind me about it. 万一我忘记,请请醒我一下。
注意,在条件状语从句中,通常要用一般现在时表示将来意义,而不能直接使用将来时态。
不过,有时表示条件的 if之后可能用 will,但那不是将来时态, 而是表示意愿、委婉请求或执意等,此时的will为情态动词。

初中语法 从句中的时态问题
初中语法从句中的时态问题从句中的时态问题从句作为一个句子的组成部分,承担着为主句提供更多信息的任务。
在从句中,时态的使用是十分重要的,正确的时态可以保证句子的准确表达,避免歧义。
在初中语法中,对从句中的时态问题的理解和运用是非常关键的。
本文将介绍从句中常见的时态问题,并提供相应的解决方法,帮助同学们更好地理解和掌握初中语法。
一、宾语从句中的时态问题宾语从句是指在一个句子中作为宾语的从句。
宾语从句一般由连接词that引导,也可以由疑问词(如what, where, when, how等)引导。
宾语从句中的时态与主句的时态有紧密的联系。
1. 当主句的谓语动词是一般现在时、一般将来时或一般过去时时,宾语从句的时态要根据实际情况来选择。
例如:He says (that) he is a student.(现在时态)She said (that) she would go shopping tomorrow.(将来时态)They knew (that) she had finished her homework.(过去时态)2. 当主句的谓语动词是一般过去时,表示客观的事实或真理时,宾语从句要使用一般现在时。
例如:He said (that) the earth revolves around the sun.(过去时态)3. 当主句的谓语动词是过去时的某种特殊形式(如过去进行时、过去完成时等)时,宾语从句的时态要根据实际情况选择。
例如:He said (that) he was watching TV when she arrived.(过去进行时态)二、条件从句中的时态问题条件从句表示条件和结果之间的关系,通常由if引导。
1. 当条件从句表示的是与现在或将来相反的情况时,谓语动词要使用虚拟语气,即过去时态。
例如:If I were you, I would study harder.(与现在相反的情况)2. 当条件从句表示的是与过去相反的情况时,谓语动词要使用过去完成时。
