中考英语难点语法条件状语从句：“主将从现”&巩固练习
相信大家对于“主将从现”这一说法并不陌生，中学老师给我们的例子“如果明天不下雨，那么我们就去野炊吧”从我念初中开始至今还仍然在使用，但是说到底你是否了解其中的用法呢？下面就由我来给大家一一详述。
首先我们知道一个句子的成分包含，“主谓宾定状补”，那么在句中作状语的从句称为状语从句。状语从句由从属连词引导，它可以表示时间、地点、原因、目的、结果、条件、让步、比较和方式。今天给大家详细讲解其中的一种条件状语从句，它常由if，unless，as long as等引导。
一、由if引导的条件状语从句，意为“如果”
1.He will come if you invite him.
---如果你邀请他的话，他将会来的。
2.They won't go to the beach if it rains.
---如果下雨的话，他们将不会去沙滩。
3.Your parents will be happy if you study hard.
---如果你学习努力的话，你的父母将会很开心。
主句用一般将来时，if引导的条件状语从句用一般现在时。
这就是我们经常听到的“主将从现”，那么除了“主将从现”以外还存在“主情从现”“主祈从现”。
主句有情态动词，从句用一般现在时。
1. If you are hungry, you should eat something.
2. If you feel tired, you must have a rest.
主句是祈使句，从句用一般现在时。
1. Come with me if you have time
2. Don't be sad if you fail the exam.
接下来我们来做几个小练习吧！检测一下自己是否真正掌握知识呢！

3. I get up late. Don't wait for me.

重点拓展：if从句还可以表示不可实现的条件或不存在的条件，即一种虚拟条件或者假设，从句多用一般过去时或过去完成时。
1. What would you do if you had a million dollars 如果你有100万美元你会做什么？
2. If I were a boy --- Beyonce
除了if以外，还有unless，as long as等引导条件状语从句，它们同样遵循“主将从现”的规则，在这里就不加以赘述了，下面就以这些词的用法以例句的形式进行一下简单总结。
二、由unless引导的条件状语从句，意为“除非”，unless 等于if... not...
1.如果明天不下雨，我们就去远足。
If it doesn't rain tomorrow, we'll go hiking.
=We'll go hiking unless it rains tomorrow.
2.如果你不把肉存放在冰箱，它就会变质。
If you don't keep the meat in the fridge, it goes bad.
=Unless you keep the meat in the fridge, it goes bad.
三、由as long as 引导的条件状语从句，意为“只要”
1. As long as you love me. --- Justin Bieber
2. We'll go as long as the weather is good.
---只要天气好我们就去。
3. But I think friends are like books --- you don't need a lot of them as long as they're good.
