Grammar focus —I think I ' ll take the bus to the party. —If you do, you ' ll be late. If you take the bus to the party, you —I think I ' ll stay at home. —If you do, you ' ll be sorry.

一地点状语从句 地点状语从句通常由where, wherever 引导。 Where I live there are plenty of trees.我住的地方树很多。 Wherever I am I will be thinking of you. 不管我在哪里我都会想到你。 二. 方式状语从句 方式状语从句通常由as, (just) as…so…, as if, as though引导。 1）as, (just) as…so…引导的方式状语从句通常位于主句后，但在(just) as…so…结构中位于句首，这时as从句带有比喻的含义，意思是"正如…"，"就像"，多用于正式文体，例如：Always do to the others as you would be done by.你希望人家怎样待你，你就要怎样待人。As water is to fish, so air is to man.我们离不开空气，犹如鱼儿离不开水。 Just as we sweep our rooms, so we should sweep backward ideas from our minds. 正如打扫房屋一样，我们也要扫除我们头脑中落后的东西。 2）as if, as though 两者的意义和用法相同，引出的状语从句谓语多用虚拟语气，表示与事实相反，有时也用陈述语气，表示所说情况是事实或实现的可能性较大。汉译常作"仿佛……似的"，"好像……似的"，例如： They pletely ignore these facts as if (as though) they never existed. 他们完全忽略了这些事实，就仿佛它不存在似的。（与事实相反，谓语用虚拟语气。） He looks as if (as though) he had been hit by lighting. 他那样子就像被雷击了似的。（与事实相反，谓语用虚拟语气。） It looks as if the weather may pick up very soon. 看来天气很快就会好起来。（实现的可能性较大，谓语用陈述语气。） 说明：as if / as though也可以引导一个分词短语、不定式短语或无动词短语，例如： He stared at me as if seeing me for first time.他目不转睛地看着我，就像第一次看见我似的。He cleared his throat as if to say something.他清了清嗓子，像要说什么似的。 The waves dashed on the rocks as if in anger.波涛冲击着岩石，好像很愤怒。 三. 原因状语从句 比较：because, since, as和for 1）because语势最强，用来说明人所不知的原因，回答why提出的问题。当原因是显而易见的或已为人们所知，就用as或since。 I didn't go, because I was afraid. Since /As the weather is so bad, we have to delay our journey. 2）由because引导的从句如果放在句末，且前面有逗，则可以用for来代替。但如果不是说明直接原因，而是多种情况加以推断，就只能用for。 He is absent today, because / for he is ill. He must be ill, for he is absent today. 四. 目的状语从句 表示目的状语的从句可以由that, so that, in order that, lest, for fear that, in case等词引导，例如：
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

【英语】状语从句基础测试题 一、初中英语状语从句 1．She looked behind from time to time ________ she went in the dark. A．when B．as C．while D．before 【答案】B 【解析】 【详解】 句意：她在黑暗中走着，不时回头看看。考查连词辨析。when，while都可表示“…… 时候”；when引导的从句，谓语动词既可以是延续性动词，也可以是非延续性动词；while引导的从句，谓语动词必须是延续性动词，而不能是非延续性动词；as表示“在……期间”“随着”；before“在……之前”，常与过去时，一般现在时等连用。根据句意语境，可知她一边走一边回头看，as切合句意，故选B。 2．Tony has had to cook by himself ________ his mother went on business to Guangzhou. A．since B．after C．during D．when 【答案】A 【解析】 【详解】 句意：自从妈妈去广州出差以来，托尼不得不自己做饭。A. since从……以来；B. after在……之后；C. during 在……期间；D. when当……时候。since后跟时间状语从句时，表示的是到目前为止的时间段，从句时态为一般过去时，而主句的时态为现在完成时，故正确答案为A。 3．Our eyesight will become poorer and poorer we keep playing with phones. A．though B．unless C．if 【答案】C 【解析】 【详解】 句意：如果我们继续玩手机，我们的视力会越来越差。 A. though尽管，虽然； B. unless除非； C. if如果。这里是if引导的条件状语从句，遵循主句用一般将来时，从句用一般现在时态，根据题意，故选C。 4．WeChat Pay makes our lives confident. ______ we want to pay for something, we just need to scan a QR code（扫描二维码）.

初中英语If引导的条件状语从句演示教学
初中英语――if引导的条件状语从句 在if 引导的条件状语从句中，if 和条件句位置灵活，可直接放在主句后面，若if 条件句放句首，从句后面要加逗号，和主句隔开。还要注意前后时态一致原则.引导条件状语从句的连接词主要有：if(如果）、unless（除非）或as long as （只要）等。unless在意思上等于if...not。 一、条件状语从句用法 1、引导条件状语从句最常用的连词是if,由if引导的条件状语从句表示在某种条件下某事很可能发生。如： If you ask him, he will help you. 如果你请他帮忙,他会帮你的。 If you fail in the exam, you will let him down. 如果你考试不及格,你会让他失望的。 另外,if从句还表示不可实现的条件或根本不可能存在的条件,也就是一种虚拟的条件或假设,从句多用一般过去时或过去完成时。如: If I were you, I would invite him to the party. 如果我是你,我会邀请他参加聚会。 2、unless = if...not.除非,若不,除非在……的时候 例如：Let's go out for a walk unless you are too tired. =If you are not too tired, let's go out for a walk. Unless it rains, the game will be played. 除非下雨,比赛将照常进行。 二、时态问题 在条件状语从句中，要注意“主将从现”的规定，即主句用一般将来时，从句用一般现在时表示将来时。例句： I will come to see you if I have time. 我有时间，我就来看你。 三如果if 条件句谈论的是重复发生和预示要发生的情景和事件，则主从句大多用一般现在时态。如： If bears are in danger ,they attack people. 误区提醒 if 既可以引导条件状语从句，表示“如果”，也可以引导宾语从句，表达“是否”。辨别它在这两种从句中的时态是我们经常容易出错的地方。另外，if 和unless的用法也需注意。 典型例题：----I wonder if your wife to the party. ----If your wife _________, so will mine。. A. will go，go B. will go, goes C.goes, will go D. will go, will go 解析：第一句中if表示“是否”，引导宾语从句，用将来时will go；第二句“如果你的妻子去，我的妻子也去”，if引导条件状语从句，用一般现在时表示将来时。your wife，单三人称主语，所以用goes 。
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.

状语从句——条件状语从句 教案
一、复习预习 状语从句指句子用作状语时，起副词作用的句子。它可以修饰谓语、非谓语动词、定语、状语或整个句子。根据其作用可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等从句。状语从句一般由连词(从属连词)引导，也可以由词组引起。从句位于句首或句中时通常用逗号与主句隔开，位于句尾时可以不用逗号隔开。 二、知识讲解 知识点： 【考查点1】 引导条件状语从句最常用的连词是if，常见的if条件状语从句表示在某条件下，某事很可能发生，条件是可能存在的，主句中某种情况发生的概率也是很高的。如： If you ask him，he will help you．如果你请他帮忙，他会帮你的。 If you fail in the exam，you will let him down．如果你考试不及格，你会让他失望的。 If you have finished the homework，you can go home．如果你作业做完了就可以回家了。 另外，if从句还表示不可实现的条件或根本不可能存在的条件，也就是一种虚拟的条件或假设。从句多用一般过去时或过去完成时，表示对现在或过去的一种假设。如：
If I were you，I would invite him to the party．如果我是你，我会邀请他参加聚会。 I would have arrived much earlier if I had not been caught in the traffic．要不是交通堵塞，我本会来得早一些。 【考查点2】 另外要注意if 条件句的时态搭配 1．if从句用一般现在时，主句用一般将来时 If he runs he’ll get there in time. 如果他用跑的，他就会及时赶到那儿。 The cat will scratch you if you pull her tail. 如果你拉猫的尾巴，它就会抓你。 2．if从句用一般现在时，主句用may/might/can If the fog gets thicker the plane may/might be diverted. 如果雾在大一些，飞机可能就会改在别的机场降落。 If it stops snowing we can go out. 如果雪停了，我们就可以出去。 3．if从句用一般现在时，主句用must/should If you want to lose weight you must/should eat less bread. 如果你想减肥，你必须少吃面包。 4．if从句用一般现在时，主句用一般现在时 If you heat ice it turns to water. (也可用will turn)如果把冰加热，它就会化成水。 5．if从句用现在进行时，主句用一般将来时 If you are looking for Peter you’ll find him upstairs. 如果你是在找彼得，上楼就会找到他。 6．if从句用现在完成时，主句用一般将来时
