【优质文档】if引导的条件状语从句和宾语从句

If的用法if 的条件从句分为真实条件从句和虚拟条件从句。

真实条件从句：真实条件从句适用于主将从现，是假设有可能发生的。

一．位置在if 引导的条件状语从句中，既可以放在主句之前，也可以放在主句之后。

若if 条件句放句首，从句后面要加逗号，和主句隔开。

You will catch the bus if you get up early. = If you get up early, you will catch the bus.二．时态1.（主祈从现）主句：一般现在时态（包含祈使句和含有情态动词can, may, must等的句子）从句：一般现在时态2. （主将从现）主句：一般将来时态从句：一般现在时态3.从句:现在进行时，主句: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。

4．if从句用现在完成时，主句用一般将来时If you have finished dinner I’ll ask the waiter for the bill. 如果你吃完了，我就叫服务生来算账5.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.三．注意事项1.在if 引导的条件状语从句中，当主句是一般将来时态时，不能使用be going to 结构，而要用will.2.在if 引导的条件状语从句中,不能使用some,而要用any.四．同义句转化1.借助于祈使句+and∕or+简单句转化，and表示顺承，or表示转折。

例如：(1)If you work hard, you’ll pass the exam.Work hard, and you’ll pass the exam.(2)If you do n’t hurry up, you’ll be late.Hurry up, or you’ll be late.2.借助于介词with或者without 来转换例如：If you help me, I’ll finish my job soon.With your help , I’ll finish my job soon.if 条件句不一般,几个要点记心间条件句,放在前,逗号要放句中间。

【初中英语】虚拟语气专项练习题及答案详解

【初中英语】虚拟语气专项练习题及答案详解一、初中英语虚拟语气1． ---What if I have to go there and know nothing about it?--- If I______ you, I would try to find some information about it on the Internet.A．am B．was C．will be D．were【答案】D【解析】试题分析：句意：——倘若我必须去那儿而且对那里一无所知，该怎么办？——如果我是你，我会在网上查找一些有关那里的信息。

根据I would try to find可知主句用的是would+do,可知这是对现在事实的假设的虚拟语气，因此If引导的条件状语从句用一般过去时，根据虚拟语气的用法be动词在If引导虚拟语气中用were .故选 D。

考点：考查虚拟语气的用法。

2．If I _____ you, I _____ late for school this morning.A．were, wouldn’t be B．were, wouldn’t C．was, won’t be D．am, will【答案】A【解析】试题分析；句意：如果我是你，今天早晨我上学就不会迟到。

与现在事实相反，故从句用过去时态，主语用过去将来时态。

选项B缺少谓语动词。

故选A。

考点：if引导的条件状语从句点评：虚拟语气是一种特殊的动词形式，用来表示说话人所说的话并不是事实，而是一种假设、愿望、怀疑或推测。

判断是真实条件句还是非真实条件句。

只有在非真实条件句中才使用虚拟语气。

通过句子意思，看假设的条件是否能够实现，能够实现是真实条件句，不能使用虚拟语气；假设的条件不能实现则是非真实条件句，要用虚拟语气.判断这个假设是与哪个事实相反。

1、与现在事实相反若与现在事实相反，条件从句的谓语用过去式（be通常用were），主句谓语用“should （would, could, might）+动词原形”2、与过去事实相反若与过去事实相反，条件从句的谓语用过去完成时（had+过去分词），主句谓语用“should （would, could, might）+have+过去分词”3、与将来事实相反若与将来事实相反，条件从句的谓语用过去式（be通常用were），主句谓语用“should （would, could, might）+动词原形”。

动词的时态专项练习(附答案)

考点：考查完成时态的用法。
15．---Where is Mr. Wang?
---He together with his students _______ Haibin Park．
A．have gone to B．has gone to C．has been to D．have been to
【答案】B
2．Ken, can you turn down the music a little? I _________ to study for my test.
A．am trying B．try C．tried D．have tried
【答案】A
【解析】
句意：Ken，你能把音乐调小一点吗？我正在设法为我的考试学习。根据语境可知用现在进行时，其结构是be doing的形式，短语try to do sth.表示设法做某事。根据题意，故选A。
4．— I’m not sure if my sister Vivian ____________ the driving test next week.
— Please let me know if she ____________ it.
A．has passed; passes B．passed ; will pass C．passes; has passed D．will pass; passes
【答案】C
【解析】句意：-嗨，Lily，我昨晚八点给你打电话了，但是没人接电话。-哦，我当时在洗澡。具体到了过去某个时间段，描述过去那段时间里进行的动作用过去进行时，结构是was/were doing，这里表示的是“我当时正在洗澡”，故选C。
12．--Look! There____ so many noisy kids in the room!

if引导的条件状语从句讲解和练习(答案)编辑整理：尊敬的读者朋友们：这里是精品文档编辑中心，本文档内容是由我和我的同事精心编辑整理后发布的，发布之前我们对文中内容进行仔细校对，但是难免会有疏漏的地方，但是任然希望（if引导的条件状语从句讲解和练习(答案)）的内容能够给您的工作和学习带来便利。

同时也真诚的希望收到您的建议和反馈，这将是我们进步的源泉，前进的动力。

本文可编辑可修改，如果觉得对您有帮助请收藏以便随时查阅，最后祝您生活愉快业绩进步，以下为if引导的条件状语从句讲解和练习(答案)的全部内容。

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’t 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。
