句子的类型
Grammar
状语从句（Adverbial Clause） 是指句子用作状语时，起副词作用的句子。 状语从句根据其作用可分为时间、地点、原因、条件、目的、结果等从句。 状语从句一般由连词(从属连词)引导，也可以由词组引起。
While John was watching TV, his wife was cooking. （时间状语从句）
当约翰看电视时，他的妻子正在做饭。
He didn’t attend classes yesterday because he was ill. （原因状语从句）
他病了，所以他昨天没有来上课。
He got up so early that he caught the first bus. （目的状语从句）
他很早起床以便赶上第一班公共汽车。
We’ll start our project if the president agrees. （条件状语从句）
如果总统同意，我们将开始我们的项目。
状语从句
Grammar
if引导的条件状语从句
在复合句中作条件状语的句子叫条件状语从句。 条件状语从句常用if来引导。If从句既可放在主句前，也可放在主句后。放在主句前，要用“,”与后面的主句隔开。
语法概述
Grammar
if条件句放在前，逗号要放主句前。
if条件句表如果，主将从现是关键。
if引导的条件状语从句
一.含条件状语从句的复合句中主从句的时态
主句为以下情况之一时，条件状语从句用一般现在时：
（1）主句是一般将来时。
If it doesn’t rain tomorrow, we will go to the zoo.
（2）主句谓语部分含有情态动词（may, might, can, must, should等）。
If you eat bad food, you may fall ill.
（3）主句为祈使句。
If the light is red, wait for a minute.
经典例句！
巧学妙记
Grammar
二. 有些句子可与含if条件状语句互相转换。
（1）祈使句 + and/or + 陈述句。
Hurry up, or you’ll miss the train. = If you don’t hurry up, you’ll miss the train.
You will be healthier if you eat well. = Eat well and you will be healthier.
（2）借助with或without。
You can’t drive the car with the door open. = You can’t drive the car if the door is open.
If there is no water, fish will die. = Fish will die without water.

if 条件句不一般，几个要点记心间；
条件句，放在前，逗号要居中间；
条件句表可能，主句多用将来时；
条件句表事实，主句常用现在时。
注意：
1.if还可以用于宾语从句中，表示“是否”，相当于 whether，引导宾语从句，时态需根据语境确定。
如：I don't know if he will come tomorrow. If he comes，I will tell you.我不知道他明天是否会来。如果他来，我就会告诉你。(前一个if表示“是否”，引导宾语从句； 后一个if表示“如果”，引导条件状语从句)
2.If条件句的同义句：
（1）借助“祈使句+and/or +句子（一般将来时结构）”这一句型来转换。其中，在句意上and表示顺承；or表示转折，意为“否则”。即祈使句，and /or+将来时态的陈述句。
Work hard ,and you will make great progress.（and 并且）
=If you work hard,you will make great progress.
如果你努力学习，你才会取得大的进步。
Hurry up, or you will be late.（or 否则）
=If you don't hurry up. you will be late.
如果你不快点，你就要迟到了。
（2）借助without或with来转换条件状语从句。
If there is no water, fish will die.=Fish will die without water.
