本文将详细解释状语从句的定义、功能和常见类型，并给出一些例句以帮助读者更好地理解和运用状语从句。
状语从句是一个从句，它在句子中充当状语的角色，用来说明动作发生的时间、地点、原因、方式、条件等情况。
状语从句通常由连词引导，常见的引导词包括when（当...时候）、where（在...地方）、why（为什么）、how（如何）等。
通过使用状语从句，我们可以使句子更加丰富、具体和准确。
首先，让我们来看一下状语从句的功能。
状语从句可以用来表示时间关系。
例如，“I will call you when I arrive home.”（当我到家时，我会给你打电话）这个例句中的状语从句“when I arrive home”说明了动作“call”发生的时间。
其次，状语从句可以表示地点关系。
例如，“She looked around to see where the noise was coming from.”（她四处看看，想知道声音是从哪里传来的）这个例句中的状语从句“where the noise was coming from”说明了动作“look around”的地点。
此外，状语从句还可以表示原因、条件和方式等关系。
例如，“He couldn't go to the party because he was sick.”（他因为生病所以不能去参加聚会）这个例句中的状语从句“because he was sick”表示了动作“couldn't go”的原因。
在使用状语从句时，需要注意一些语法规则。
首先，状语从句通常放在主句之前或之后，具体位置取决于需要强调的内容。
其次，状语从句的谓语动词通常使用一般现在时，而不受主句的时态影响。
例如，“I will call you when I arrive home.”（当我到家时，我会给你打电话）中的“arrive”使用的是一般现在时。

状语从句3．1 方式状语从句方式状语从句通常由as, (just) as…so…, as if, as though引导。
1）as, (just) as…so…引导的方式状语从句通常位于主句后，但在(just) as…so…结构中位于句首，这时as从句带有比喻的含义，意思是"正如…"，"就像"，多用于正式文体，例如：Always do to the others as you would be done by.你希望人家怎样待你，你就要怎样待人。
As water is to fish, so air is to man.我们离不开空气，犹如鱼儿离不开水。
Just as we sweep our rooms, so we should sweep backward ideas from our minds.正如打扫房屋一样，我们也要扫除我们头脑中落后的东西。
2）as if, as though两者的意义和用法相同，引出的状语从句谓语多用虚拟语气，表示与事实相反，有时也用陈述语气，表示所说情况是事实或实现的可能性较大。
汉译常作"仿佛……似的"，"好像……似的"，例如：They completely ignore these facts as if (as though) they never existed.他们完全忽略了这些事实，就仿佛它不存在似的。
（与事实相反，谓语用虚拟语气。

so 还可与表示数量的形容词many, few, much, little连用，形成固定搭配。
so foolish such a foolso nice a flower such a nice flowerso many / few flowers such nice flowersso much / little money. such rapid progressso many people such a lot of people（so many 已成固定搭配，a lot of 虽相当于many，但 a lot of 为名词性的，只能用su ch搭配。
）so…that与such…that之间的转换既为so与such之间的转换。
