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。

(完整word版)初中英语If引导条件状语从句

初中英―― if 引的条件状从句在 if 引的条件状从句中， if 和条件句地点灵巧，可直接放在主句后边，若 if 条件句放句首，从句后边要加逗号，和主句分开。

要注意前后一致原 .引条件状从句的接主要有： if( 假如）、unless（除非）或 as long as（只需）等。

unless在乎思上等于 if...not。

一、条件状从句用法1、引条件状从句最常用的是if, 由 if 引的条件状从句表示在某种条件下某事很可能生。

如：If you ask him, he will help you.假如你他帮忙 ,他会帮你的。

If you fail in the exam, you will let him down.假如你考不及格 ,你会他绝望的。

此外 ,if 从句表示不行的条件或根本不行能存在的条件 ,也就是一种虚的条件或假 ,从句多用一般去或去达成。

如 :If I were you, I would invite him to the party.假如我是你 ,我会邀他参加聚会。

2、 unless = if...not. 除非 ,若不 ,除非在⋯⋯的候比如：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 ,比将照旧行。

二、在条件状从句中，要注意“主将从”的定，即主句用一般未来，从句用一般在表示未来。

例句：I will come to see you if I have time.我有，我就来看你。

三假如 if 条件句的是重复生和示要生的情形和事件，主从句大多用一般在。

如：If bears are in danger ,they attack people.区提示if 既能够引条件状从句，表示“假如”，也能够引从句，表达“是否”。

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。

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。
