if引导的条件状语从句讲解和练习(答案)

t 条件状语从句 一、 条件状语从句通常由 if (如果), unless (除非),as long as (只要)引导。 例如:If it rains tomorrow, we won ’go to the park. 如果明天下雨,我们就不去公园了。 Unless weather stops me, I go for a walk every. 我每天都会去散步,除非遇上坏天气。 Our parents will be pleased with our performance as long as we try our best. 小试牛刀:1、只要我们竭尽全力,父母就会满意我们的表现。 Our parents will be pleased with our performance _____ _____ ______ we try our best. 2、如果人人为保护环境做出贡献,世界将会变得更美好。______ ______ ______ _____ _______ to protecting the environment, the world will become much more beautiful. 二、if 引导的条件状语从句 (1)“if 从句+祈使句”的句子。其实,if 作为一个连词,主句也可以是其他形式的句子。 例如:If you want to go, please let me know. If the green light isn ’t on, wait for a minute. (2)“祈使句 + and (or)+ 陈述句” 在意思上相当于一个带有条件状语从句的复合句。 注意:A. “祈使句 + and + 陈述句”可以转化为 if 引导的肯定条件状语从句,而且主语是第二人称。 B. “祈使句 + or + 陈述句”可以转化为 if 引导的否定条件状语从句,而且主语是第二人称。 例如:Study hard and you will pass the exam. =If you study hard, you will pass the exam. Hurry up, or you ’ll be late. =If you don ’t hurry up, you ’ll be late. 考题 (2010 重庆中考)Work hard ,________ you may catch up with your classmates soon. A.or B.but C.and D.yet 思路解析:本句是“祈使句+and”的句型,句意为“努力学习,你会很快赶上其他同学的”,and 在句中表示承接 关系,所以选 C 项。答案:C 黑色陷阱:本题的陷阱是句型,本句型区别于“祈使句+or”,这个句型的含义是“……,不然的话/否则……”。 绿色通道:祈使句后面既可以加 and ,也可以加 or ,所以要全面分析句意,再作决定。 小试牛刀:用 if 连接下列句子 1、Go to bed early and you will have a good rest. 2、Hurry up, or you ’ll miss the bus. 三、if 从句与主句具有以下特点: 1.If 从句中用一般现在时,表示未来的一种条件,从句中可以加时间状语。 e.g.If yo u can’t come tomorrow, we can hold the party a little later.明天你如果不能来,我们可迟一点举行宴会。

If引导条件状语从句的详细用法解答

If引导条件状语从句的详细用法解答 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。 另外你还要注意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.

初中英语知识点总结:方式和地点状语从句

一、方式状语从句 1、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: Please do as what I told you.请按照我告诉你的做。 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: He looks as if (as though) he had been hit by lightning. 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 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。 2、其他的引导词 1)the way:Please pronounce the word the way I do.请照我这样,读这个单词. 2)口语常用的like:He sit there smiling like it was his birthday.他面带微笑坐在那儿,像是过生日似的. (这里用了虚拟语气,值得注意的是be动词用的was,而表示虚拟as if引导的be动词则只能是were。) 地点状语从句表示地点、方位,这类从句通常由where,wherever引导。例如: Where there is a will, there is a way. 有志者,事竟成。 They will go where they are happy. 他们想到他们觉得快乐的地方去。 二、地点状语从句 1、地点状语从句类型 1)Where+地点从句。此句型通常译成“哪里……哪里就……”或“····的地方”。例如:Where there is no rain, farming is difficult or impossible.在没有雨水的地方,耕作是困难的,或根本不可能的。 They were good persons. Where they went, they were warmly welcomed. 他们都是好人。因此他们走到哪里都受到热烈欢迎。 You should have put the book where you found it. 你本来应该把书放回原来的地方。We must camp where we can get water. 我们必须在能找到水的地方露营。 2)Anywhere/ wherever+地点从句,+主句。 anywhere本身是个副词,但是,常可以引导从句,相当于连词,意思相似于wherever, anywhere 引导的从句可位于主句之前,也可以位于主句之后。而wherever本身就是个连词,表示“在何处,无论何处”。例如: Wherever the sea is , you will find seamen.有海就有海员。 2、地点状语从句与定语从句的区别 二者区别在于分句在句中作什么成分。作状语,则是状语从句;作定语修饰名词,则是定语从句。where引导定语从句时,从句前应有一个表示地点的名词作先行词;而状语

高中英语语法---条件状语从句讲解

条件状语从句 概念定义 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”。(注意:在含有条件状语从句的复合句中,表示将来时态,主句是一般将来时态,祈使句或情态动词,从句要用现在时态,[主将从现原则](主将从现,将并非指将来时,还指表示将来含义的,跟着if后的那句话是从句。) 类型 条件状语从句 语法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: 1) If you ask him,he will help you. 如果你请他帮忙,他会帮你的。 2) 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引导的条件状语从句既可以将从句放前面也可以将从句放后面 (如果天下雨,我们就不玩了)If it rains,we will stop playing.‘ 转为We will stop playing if it rains. if引导的条件状语从句

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。I would have arrived much earlier if I had not been caught in the traffic.如果没有堵车,我会到的早一点儿。 那么,除了if之外,是否还有其他连词也可以引导条件状语从句呢?回答是肯定的,不仅有,还有很多。这些词由于出现的频率较小,且用法较复杂一些,所以不如if为大家所熟知罢了。下面就这些词的用法以例句的形式进行一下简单总结。 1、unless conj.除非,若不,除非在……的时候 You will fail to arrive there in time unless you start earlier.如果你不早点动身,你就不能及时赶到那儿。 Unless it rains,the game will be played.除非下雨,比赛将照常进行。 2、on condition(that)...在……条件下,如果 on condition (that)...引导的条件从句是主句事件发生的前提条件或唯一条件。 I can tell you the truth on condition that you promise to keep a secret.我可以告诉你真相,条件是你答应保密。 You can go swimming on condition (that) you don't go too far from the river bank.你只有在不远离河岸的条件下才可以下水游泳。 3、supposing conj.如果,假如 supposing引导的条件从句表示一种假设条件。 Supposing it rains,shall we continue the sports meeting?倘若下雨,我们的运动会还要继续举行吗?

状语从句用法讲解和练习

第章状语从句 学习指导 状语从句在句子中作状语,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。现分别列举如下: 状语从句分九类: 在这一章节的学习中,要求同学们掌握各类状语从句基本概念,并能够灵活应用。 第一节时间状语从句 时间状语从句用一般现在时表示将来。连接时间状语从句的连接词有:2.when,while,as均可表示“当……的时候”。 when强调“特定时间”,表示主句谓语动词的动作与从句谓语动词的动作是同时发生的,或从句的动作发生在主句的动作之前;while表 示的时间是一段,而不是一点,as多用在口语中,强调“同一时间”或“一前一后”,有时还有“随着”的含义。 When spring came, he felt like a trip.春天来了,他想去旅游。 As spring warms the good earth,all flowers begin to bloom.(as有“随着”的含义) as, when, while都表示主、从句的动作或状态同时发生,但三者也有

区别。as和when引导的从句既可表示一点时间,也可表示一段时间,从句中的谓语动词既可以是持续性动词,也可以为短暂性动词,经常可以互换使用;while引导的从句通常表示一段时间,从句中宜用持续性动词作谓语。当从句中的谓语动词为持续性动词时,这三者可以通用(前面例句中已有体现),再如: 1 / 18 Mother was worried because little Alice was ill, especially as / when / while father was away in France.妈妈担心,因为小艾丽思病了,特别是当父亲远在法国的时候。 如果从句和主句要表示一个人的两个动作交替进行或同时完成时,则多用as,可译为“一边......,一边......”。例如: He looked behind from to time as he went.他一边走,一边不时地往后看。 As time goes on, it's getting warmer and warmer..随着时间的推移,天气变得越来越暖了。 I thought of it just as you opened your mouth.你一张嘴我就知道你要 说什么。(若表示两个短促动作几乎同时发生时,用as的场合多于when.) 当主从句之间表示转折或对比关系时,多用while, 不用as或when。如:

总结好的:if引导的条件状语从句

if引导的条件状语从句 if 1) 用法: (1)条件状语从句通常由连词if引导,意为“如果、假如”,主句不能用be going to表示将来,而应该用shall,will。 If you leave now, you are never going to regret it. (错误) If you leave now, you will never regret it. (正确) (2)if “如果”,引导条件状语从句,主句用一般将来时,从句则用一般现在时,如: If it rains tomorrow, I shan’t climb the hills. (3)另外,主句是祈使句或含有情态动词,从句也用一般现在时。如: Please call me if he comes next Sunday. Can you call the policeman if you are in the trouble. 注意宾语从句中的if与条件状语从句if的区别。宾语从句中的if“是否”相当于whether,引导宾语从句,时态需根据语境确定。如果主句用一般现在时,从句可以根据具体情况选用时态,如果主句用一般过去时,从句必须用过去式的某种形式。 I don't know if it will rain tomorrow. 我不知道明天是否会下雨。 Our teacher said there was going to be a football match the next month.我们说下月将有场足球比赛。 【边学边做】用括号内所给词的正确形式填空。 1.
