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 protectingthe 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。
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。
If you drive too fast，you may have an accident.如果你把车开得太快，你可能会出事故。
You must stop if the traffic light is red.如果红灯亮了，你必须停下来。

小学英语if 引导的条件状语从句讲解
if引导的条件状语从句（包含主将从现原则）一.if的位置：if“如果”，当引导条件状语从句时，既可以放在主句前面，也可以放在主句后面。
若if引导的条件句放在句首，从句后面要加逗号与主句隔开。
例如：My mother will take me to the park if she is free.如果我妈妈有空，她就会带我去公园。
If my mother is free, she will take me to the park.如果我妈妈有空，她将会带我去公园。
（此句if引导的条件状语从句位于句首，主句位于其后，所以要用逗号隔开）二.时态的运用注意：在if的条件状语从句中，主句为下列情形之一时，if条件状语要用一般现在时。
1.主句是一般将来时（主将从现）例如：If he comes, he will tell me all.如果他来了，他会告诉我所有（的事情）。
（这个知识点在初中阶段是常考题，简称“主将从现”——主句是一般将来时态，从句是一般现在时态。
本句中主句是由will引导的一般将来时态的句子，从句是由if引导的一般现在时态的句子，符合主将从现的法则。
）2.主句是含有情态动词may/might/can/must/should等句子。
例如：If you want to lose weight, you must eat less bread.如果你想减肥，你必须少吃面包。
（主句中含有情态动词must，所以if引导的条件状语从句要用一般现在时态。
）3.主句是祈使句例如：If you are not strong enough, please don't take part in such an activity.如果你不够强壮，请不要参加这种活动。
（主句是一个Do型的祈使句，所以根据原则，if从句要用一般现在时态。
——不清楚Do型祈使句的小伙伴可以查看冉老师历史发文记录）三．习题1.If you to be a rich man ,you should try hard.A. wantingB. wantedC. wantD.are want2. If you English, you can be an English teacher.A. likingB. likedC. likeD. are like3. If you like sports , you a PE teacher.A. areB. mustC. can beD. could。

may/might/can。
