you will have a great time. you will be late.

If they have it today, half the class won 'come

If we ask people to bring food, they will just bring potato chips and chocolate. 以上几个句子中“ if ”有相同的含义“如果”，引导条件状语从句逗号后面的句子是主句。整个连起来的大句子叫主从复合句。

注意主句和从句的时态有什么特点。

总结：If 引导的条件状语从句用一般现在时，主句用一般将来时。

简称“主将丛现”一

练习：(1) If you _______ (come)here, you ____________ (be) happy.

(2) If it _______ (ra in) tomorrow, we ____________ (not, go) to the park.

(3) If he ________ (come) here, I ___________ (call) you.

(4) If it _________ (n ot rai n), we _________ (have) a pic nic 野餐).

(9) If he _____ (take) a taxi, it ________ (be) too expensive.

(10) If I _______ (go) to the movies, I ____________ (fini sh) my homework.

条件状语从句的引导词还有“ unless 除非(否则)，如果不”

You won't pass the exam uni ess you study hard.

、观察下面的句子 you do,

you will be sorry. you go to the party,

you do ,

Un less you deal with(处理)your problems, you will be un happy.

二、同样when可以引导状语从句“主将从现”也适合

也就是说：when引导的时间状语从句也是一般现在时，

主句也是一般将来时。

What are you going to be whe n you grow up?

What is he going to be whe n he grows up?

三、“主将从现”的含义扩充

主：表示主句

将：(1)主句是一般将来时

Y ( 2)主句是祈使句

<-(3) 主句含有情态动词can、may、must/have to

从：表示状语从句

现：表示状语从句是一般现在时

例句：

(1) D on't go and play football if your homework ____________ (not fini sh).

(2) lf it __________ (not rai n) tomorrow, we _____________ (go)to climb the hill.

(3) He wo n't leave until you _______________ (agree)with him.

2 / 4

A. don't rain

B.w on't rain

C. does n't rain

D. is n't rain 3 / 4

四、if 翻译成“是否”，引导宾语从句，时态是：一般将来时。例如： I don 'know if he will come tomorrow.

, , ■ _ _ J - I - 4-1 _ ■ -I".? * - "I" -I".- ■- ■ .1 "1 ■ "J" ■.

He asks me if I will be free .

They want to know if they will have a party next week.

注意把if 的两个意思放在一道题中考试。（主将从现宾将）

Mary wants to know if Tom will come If he comes I will call Mary. 练习：

1」don't know if it ____ t omorrow. If it ____ , we'll go out for a pic nic.

A. will rain; does n't rai n

常考的引导词 when 、 as soon as 一）、

4 / 4

2、第二种情况：主句和时间状语从句都是一般过去时态（要过去都过去）

初中英语语法——If引导的条件状语从句(讲解及练习)

条件句从句主句真实一般现在时一般将来时情态动词+动原祈使句非真实一般过去时 be动词用（were） would/could+动原初中英语――条件状语从句（讲解&练习） Ⅰ条件状语从句的定义 Ⅱ条件状语从句的引导词 1.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。 If we pay much attention to the earth, we'll have a better world. 如果我们多关爱地球，就会拥有一个更美好的世界 If it rains tomorrow, what shall we do? 如果明天下雨，我们怎么办？注意：if还可以引导虚拟条件句，表示不可实现的条件，从句中多用一般过去时或过去完成时。 What would happen if there were no water ? 如果没有水会怎样？ 2.unless引导的条件状语从句，unless的意思是如果不，除非。可与if...not互换。 You will fail in English unless you work hard. 你英语考试会不及格的，除非你更加努力。 3.as /so long as引导的条件状语从句：as /so long as意思是“只要” So long as you're happy,i will be happy. 只要你高兴，我就高兴。 Ⅲ条件状语从句的种类 Ⅳ条件状语从句的时态原则用法例句 ①主句为一般将来时态，if从句用一般现在时态（即主将从现）。We will stay at home if it rains tomorrow. 如果明天下雨，我将要呆在家。 ②主句中含有情态动词，if从句用一般现在时态。If you finish your homework, you can go home now.如果你做完了作业，你现在可以回家了。 ③主句为祈使句，if从句用一般现在时态。Don’t jump into the river if you feel very hot. 如果你感到很热，不要跳入河里。 ④主句为过去将来时，if从句用一般过去时态（如果涉及到be动词，一律都用were）。此时，表达的是和现实相反的推测，用虚拟语气。If I were you, I wouldn’t do it like that.如果我是你，我就不会那么做的。 If you gave me some money, I would be very happy. 如果你给我一些钱，我就会很高兴的。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. (2)“祈使句 + and (or)+ 陈述句”

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。

(完整word版)初中英语If引导的条件状语从句

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 。

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.

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.

If引导的两种从句(宾语从句和条件状语从句)

重点、难点 1. 含有if引导的条件状语从句的复合句中主从句的时态。 2. If引导的宾语从句与条件状语从句的区别。考情分析通常在单项选择、完形填空或补全、完成句子等题型中考查，分值约3—4分。知能提升（一）知识讲解【认知讲解】 I. if引导的宾语从句 if 引导宾语从句时，意思为：是否，从句的时态通常要和主句保持一致。【例句】 I want to know if he lives there. 我想知道他是否住在那儿。 He asked me if I could help him. 他问我是否能帮他。【考查点】if、whether引导的宾语从句的区别 1. if或whether引导宾语从句时，作“是否”讲，常放在动词ask、see、say、know和find out等后面。一般情况下，两者常可换用，在口语中多用if。【例句】 Nobody knows whether / if it will rain tomorrow. 没有人知道明天是否下雨。 Lucy asked whether / if they had a cotton sweater. 露西问他们是否有棉制的毛衣。 2. if或whether引导宾语从句时，要注意三个方面，即连词、语序和时态。 if或whether既不能和that 或其他连词（副词）同时使用，也不能省略。【例句】我不知道他今天是否会来。 [误] I don’t know that if(whether) he will come here today. [正] I don’t know if(whether) he will come here today. 他走过来看看猫是否出了毛病。 [误] He came to see what if (whether) there was anything wrong with his cat . [正] He came to see if (whether) there was anything wrong with his cat . if或whether引导宾语从句时，虽具有疑问的意义，但其从句应用陈述句的语序。【例句】 Did you know the way to the hospital The old woman asked me. The old woman asked me if / whether I knew the way to the hospital. 老妇人问我是否知道去医院的路。 if或whether引导的宾语从句应和主句的时态保持一致。即主句为一般现在时，从句用任一种时态；主句为一般过去时，从句则用过去时中的任一种时态。【例句】 I don’t know if (whether) he has come here. 我不知道他是否来过这儿。

If引导条件状语从句的用法

◆if引导的条件状语从句条件状语从句是在复合句中作条件状语的句子。表示假如有从句的动作发生就会有主句的动作发生。条件状语从句常由从属连词if引导。 ◆if引导的条件状语从句使用须知：一、位置 if引导的条件状语从句，既可放在主句之前也可放在主句之后。当从句置于主句之前时，常用逗号与主句隔开。例如： You will catch the bus if you get up early. =If you get up early, you will catch the bus. 如果你早起的话，就能赶上公共汽车。二、时态应遵循主、从句时态呼应的原则。当主句是一般现在时(包含祈使句和含情态动词can, may, must等的句子)，从句也用一般现在时。例如： You must see the doctor if you are ill. 如果你生病了，你必须去看医生。 If you want to go skating, wear warm clothes. 如果你想去滑冰，穿上暖和点的衣服。一．选择正确答案。 1.
