2019年秋人教版八年级Unit 10 if引导的条件状语从句讲和练(含答案及解析)
2019年秋八年级上册单元语法讲与练if引导的条件状语从句语法精讲1.条件状语从句的含义由一个主句和一个或一个以上的从句构成的句子叫复合句。
在复合句中作状语的句子叫作状语从句。
状语从句根据它表达的意思可分为很多种，if引导的句子在复合句中表示条件，作主句的条件状语，因此称为条件状语从句。
If you don’t hurry，you’ll be late.如果你不快点，你将会迟到的。
If he comes，let me know.如果他要来，通知我。
2.if引导的条件状语从句的结构if引导的条件状语从句在句中的位置比较灵活，可以放在主句之前(这时要和主句用逗号隔开)，也可以放在主句的后面(不用逗号)。
条件状语从句的结构为：if+陈述句，主语+谓语(=主语+谓语+if+陈述句)。
意为“如果……就……”。
If you ask him，he will tell you the answer.如果你问他，他就会告诉你答案。
I hope to visit her if I’m free.如果我有空，我希望去看望她。
3.if引导的条件状语从句与主句时态的一致性在复合句中，从句中动词的时态在一定程度上受到主句动词时态的制约，英语语法中称为时态呼应。
（1）在含有条件状语从句的复合句中，如果主句是一般将来时，从句则用一般现在时代替一般将来时表将来。
If it rains，I will stay at home.如果下雨，我将待在家里。
If you study hard，you will pass the examination.如果你努力学习，就能通过这次考试。
（2）如果主句含有must，may，can等情态动词，从句也要用一般现在时。

You must stop if the traffic light is red.如果红灯亮了，你必须停下来。

if引导的条件状语从句讲解
条件状语从句在句子中做条件状语的从句称为条件状语从句。
通常置于句首或句尾。
一．条件状语从句通常由if（）, unless（），as long as（）引导。
例如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？尝试一下：（补全句子）If it rains tomorrow, we won’t go to the park.______________________________________。
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。
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.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. =_________________________________________.Hurry up, or you’ll be late. =__________________________________________________..考题(2010重庆中考)Work hard，________ you may catch up with your classmates soon.A.orB.butC.andD.yet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……”。

【中考英语总复习 考点专项练习】33 条件状语从句(解析版)
专项33 条件状语从句条件状语从句，即在某种条件下，一件事情可能发生。
在英语中由连接词if或unless 等引导的状语从句叫作条件状语从句。
条件是指某一件事情实现之后（状语从句中），一件事情（主句）才能发生，通常译作＂假如，只要，如果＂等意思。
条件状语从句中，主从句的时态要遵循＂主将从现＂的原则。
即，主句是将来时态时，从句用一般现在时代替将来时态。
引导条件状语从句的连词或词组有：if(如果)，unless(除非)，as long as(只要)等。
如果主句是将来时，条件状语从句也用一般现在时来表示。
如：I will stay at home if it rains tomorrow. 如果明天下雨，我就待在家。
You can’t learn English well unless you work hard.除非你努力学习，否则是学不好英语的。
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？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。
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。

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。 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
3. 只能用whether的情况 在动词不定式之前只能用 whether： I can’t decide whether to stay. 我不能决 定是否留下。 在whether …or not 的固定搭配中： I want to know whether it’s good news or not. 我想 知道它是不是好消息。 在介词后，只能用whether： His father is worried about whether he loses his work. 他的父亲担心他是否会失去工作。 用if会引起歧 义时： Could you tell me if you know the answer? 这句话 有两种意思： “你能告诉我你是否知道答案吗？”或“如果你知道答 案，请告诉我，好吗？”。 如用whether则可避免歧义。
中考英语条件状语从句单选题30题(带答案)
中考英语条件状语从句单选题30题(带答案)1.If it rains tomorrow, we ______ stay at home.A.willB.wouldC.shouldD.must答案：A。
解析：if 引导的条件状语从句，遵循“主将从现”原则，即主句用一般将来时，从句用一般现在时。
此句中从句是“it rains tomorrow”，主句是“we will stay at home”。
选项B“would”是过去将来时，不符合；选项C“should”表示应该；选项D“must”表示必须，都不符合条件状语从句的语法规则。
2.If I have time, I ______ help you with your homework.A.willB.wouldC.shouldD.must答案：A。
解析：同样是if 引导的条件状语从句，遵循“主将从现”。
从句“if I have time”，主句“ I will help you with your homework”。
选项B“would”过去将来时不对；选项C“should”应该和选项D“must”必须不符合条件状语从句的语法规则。
3.If you study hard, you ______ get good grades.A.willB.wouldC.shouldD.must答案：A。
解析：if 引导条件状语从句“主将从现”。
从句“if you study hard”，主句“you will get good grades”。
选项B“would”过去将来时不合适；选项C“should”应该和选项D“must”必须不满足此语法规则。
4.If he ______ early, he can catch the bus.A.gets upB.got upC.will get upD.would get up答案：A。
解析：“主将从现”，从句用一般现在时，he 是第三人称单数，所以动词用gets up。

初中条件状语从句(附答案)
初中条件状语从句(附答案)条件状语从句是由连接词if或unless引导的从句。
在含有条件状语从句的复合句中，如果主句是一般将来时态，从句要用一般现在时。
if和unless是常用的引导词。
if引导的条件状语从句有真实条件句和非真实条件句两种。
真实条件句表示在某种条件下某事很可能发生，而非真实条件句是虚拟语气的一种，表示与事实相反、不可实现的条件或根本不存在的条件。
在真实条件句中，if后面的从句要紧跟着，放在前面，逗号要放在句中间。
主句多用将来时。
在非真实条件句中，从句多用一般过去时或过去完成时。
unless是if。
not的固定搭配，意为除非、若不、除非在。
的时候。
例如，You will fail to arrive there in time unless you start earlier。
= If you don't start earlier。
you will fail to arrive there in time。
除非你早点动身，否则你就不能及时赶到那儿。
1.If you feel tired。
you have to have a rest.2.Where will he see the film if he has time?3.If there were fewer trees。

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。
