（一）状语从句归纳定义状语从句用作状语，是起副词作用的句子。

地址状语从句能够放在主句从前，也能够放在主句此后，时间、条件、原因和退步状语从句放在句首时需要用逗号和主句分开。

分类依照其作用能够分为时间、地址、原因、条件、目的、退步、方式和比较等状语从句。

作用它能够修饰谓语、非谓语动词、定语、状语和整个句子。

（二）状从句解1.状从句引用法when意“当⋯的候”。

When引从句的能够是延性，也能够是瞬。

并且when 有表示“就在那”while意“在⋯的候，在⋯ 的同”。

While 引从句的必是延性的，生，并主句和从句的作同生（也许相）。

While有能够表示比。

示例A liar is not believed when he speaks the truth.者真也没有人相信。

When he arrives , I’ll call you. When you laugh and smile, your body relaxes.While I was standing at the window, I saw several boys running along the street.While John was watching TV, his wife was cooking.as意“一⋯ 一⋯”。

As 引的作是延性的，生短，一般用于主句和从句作同生； as 也能够一前一后。

after意“在⋯此后”。

表示主句作生在从句作此后。

主句与从句的作关系与before 引的从句相反。

before意“在⋯从前”。

引的从句不用否定形式的，并且当 before 引的从句位于主句此后，有成“就，才”。

当主句用将来，从句是用在；若是 before 引的从句用的是去，主句多用去完成，以便体作的先后。

till意“直到”。

一般情况下能够和 until 互。

若是主句中的是瞬，必用否定形式；若是主句中的是The writer was angry as he was travelling on a train to London because someone had invaded his “ space ”.He smiled as he stood up.With many hungry visitors waiting, don’stay too long at your table after you have finished.If an early exit is necessary, you can leave after a scene is over.You can ’ t watch TV before you finish your homework.Before it ended, the theatrewas almost empty.My father had left for Canada just before the letter arrived.She didn ’event know that it was an earthquake till she saw a shaking ( moving from side to side) light.The fireman worked very hard延性，用必定和否定形式都能够，但表达的意思不相同。

八年级条件状语从句讲练(附答案)

8年级条件状语从句一、If引导的条件句*引导条件状语从句最常用的连词是if。

if 引导的条件句有真实条件句和非真实条件句两种（非真实条件句会在以后的虚拟语气中阐述），其引导的真实条件状语从句表示在某种条件下某事很可能发生。

1、“if从句（一般现在时）+主句（一般现在时）”的条件句----表达真理或事实（动作必然发生）。

If you heat ice, it turns into water.如果你加热冰，它就会变成水。

If you put suger into water, it disappears.如果你把糖放进水里，它就会溶解。

2、“if从句（一般现在时）+主句（一般将来时）”的条件句----谈论可能发生的的事情。

If it rains tomorrow, we’ll stay at home.如果明天下雨，我们会呆在家里。

If I don’t hear from him, I won’t go. 如果没接到他的通知，我不会去。

【注】这类条件句主句部分还可以用情态动词，如I may buy a car if I pass the driving test.如果通过驾驶考试，我可能会买一辆车。

If you go to another country, you must obey the local laws.如果你去另一个国家，就必须遵守当地的法律。

3、有时if引导的条件句可以与“祈使句，and/or…”相互转换，If you don’t hurry up, you will miss the bus.=Hurry up, or you will miss the bus.快点，否则你会错过这趟车。

If you use your head, you’ll find a way.=Use your head, and you will find a way.动动脑子的话，你就会想出办法。

二、unless引导的条件状语从句unless意为“除非、如果不”，用来引导否定意义的条件句，等于“if…not…”Let's go out for a walk unless you are too tired.= If you are not too tied, let's go out for a walk. 我们出去散步吧，除非是你太累。

英语中考专项条件状语从句

英语中考专项条件状语从句第一：条件状语是在句子中用来表达某种条件或前提的短语或从句。

它们通常用来描述一个事件或情况发生的条件。

条件状语可以使用各种不同的词或短语，以下是一些常见的条件状语及其定义：1. If（如果）：表示假设条件，并指明某事可能发生的条件。

例句：If it rains, we will stay at home.（如果下雨，我们将待在家里。

）2. Unless（除非）：表示除非某个特定条件成立，否则某事将发生。

例句：I won't go out unless it stops raining.（除非停止下雨，否则我不会出去。

）3. As long as（只要）：表示只要某个条件得到满足，就会发生某事。

例句：You can stay here as long as you keep quiet.（只要保持安静，你可以在这里待着。

）注意：紧跟着引导词的是从句，另一部分是主句。

1）引导词if：（如果当然，我可以给您提供三个使用引导词"unless"的例子，并对每个例子进行详细说明：2）希望以上解释对您有所帮助！如果您还有其他问题，请随时提问。

）好的，以下是三个使用引导词"if"的例子，并对每个例子进行详细说明：1. If I work hard, I will succeed.这个句子中的主句是一般将来时态（will succeed），从句是一般现在时态（I work hard）。

条件状语"If I work hard"表示假设或前提，指出只有当我努力工作时，才会取得成功。

主句表达了一个结果，即未来的成功。

因此，这个句子传达了如果我努力工作，我将会成功的意思。

2. If it rains, we can't go for a picnic.这个句子中的主句是含有情态动词的一般现在时态（can't go），从句是一般现在时态（it rains）。
