unit6 space exploration-grammar学案条件状语从句
在复合句中，由从句表示的状语叫做状语从句。它可以用来修饰主语中的动词.形容词.副词等。根据它表达的意思，状语从句可以分为时间状语从句，地点状语从句，条件状语从句，比较状语从句，目的状语从句，结果状语从句和让步状语从句等。由连接词if或unless引导的状语从句叫做条件状语从句。（注意：在含有条件状语从句的复合句中，如果主句是一般将来时态，从句要用一般现在时[主将从现原则])
经典语句：if it doesn"t rain tomorrow, we will go to the zoo.
if you open the door，i will come in.
条件状语从句就是用以表示“在某种条件下,会……”。常用if ,in case , on condition等词来引导，连接词主要有 if, unless, as/so long as, on condition that, provided, suppose, supposing 等。主句用一般将来时，if或unless引导的条件状语从句用一般现在时。
固定搭配：unless = if...not.
e.g. 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.
if 引导的条件句有真实条件句和非真实条件句两种:
真实条件句，
如：if it rains tomorrow, we won’t go on a picnic.
非真实条件句是虚拟语气的一种，表示与事实相反，如：
if i were you, i would go with him.
so/as long as只要
由as (so) long as, in case引导。
so long as you’re happy, it doesn’t matter what you do.
只要你高兴，你做什么都没有关系。
