Module6Unit3语法专项if条件状语从句九年级英语上册精品讲义(教师版)
Module 6 ProblemsUnit 3 语法专项if条件状语从句知识精讲1.什么是if条件状语从句（概念梳理）一个句子做整句话的状语，这个句子就叫做状语从句。
根据状语从句在整句中表示的含义不同又可细分为时间状语从句、地点状语从句、原因状语从句、结果状语从句、目的状语从句、让步状语从句、条件状语从句等。
外研版英语九年级上册Module2、3、4已经系统复习了时间状语从句，原因、结果和目的状语从句，让步状语从句。
Module 5、6学习条件状语从句。
条件状语从句就是在复合句中表示主句动作发生的条件的一种状语从句。
和大多数状语从句一样，掌握条件状语从句最重要的依然是掌握连词。
条件状语从句的常用连词有：if, unless（除非）, as long as（只要）, only if（只有）, in case that, on condition that等。
初中阶段要求必须掌握的是if引导的条件状语从句。
if是引导条件状语从句最常用的连词，意为“如果”。
从句主句If you study hard, you will pass the exam.如果你努力学习，你就会通过这个考试。
主句动作：you will pass the exam前提条件：you study hard （完整句子做状语，表示主句动作发生的条件，这个句子就是条件状语从句）然后还需要用if这个连词来引导这个条件状语从句。
所以，if条件状语从句就是if引导的状语从句在复合句中作条件状语。
2.if条件状语从句的位置if引导的条件状语从句既可以放在主句之前，也可以放在主句之后。
if从句在主句前时常用逗号隔开，在主句后通常不用逗号隔开。
✧If you ever go to London, make sure you visit the Science Museum. =✧Make sure you visit the Science Museum if you ever go to London.如果你去伦敦，一定要确保去参观科学博物馆。
初中条件状语从句-精讲和练习含答案
初中英语：条件状语从句一．条件状语从句的概念条件状语从句，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做条件状语从句。
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。
二.条件状语从句的引导词1.If conj . 如果，假如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。
2.unless conj.除非,若不,除非在……的时候（if ...not...）You will fail to arrive there in time unless you start earlier. 如果你不早点动身,你就不能及时赶到那儿。
Unless it rains, the game will be played. 除非下雨,比赛将照常进行。
3.so/as long as conj.只要You may borrow my book as long as you keep it clean.只要你保持书的清洁，你就可以把我的书借去。
三．关于条件句的时态，常见的有以下三种情况：1、条件状语从句的主句是一般将来时，那么从句常常用一般现在时。
When I grow up, I’ll be a nurse and look after patients. 我长大后要当一名护士，照顾病人。
2、如果主句是祈使句，那么从句通常要用一般现在时。
If you want to have a chat ,call me up. 如果你想聊天，打我电话。
3、如果主句是含有情态动词时，根据需要从句多用一般现在时。
