1、状语从句 （Adverbial Clause） 状语从句指句子用作状语时，起副词作用的句子。它可以修饰谓语、非谓语动词、定语、状语或整个句子。根据其作用可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等从句。状语从句一般由连词(从属连词)引导，也可以由词组引起。从句位于句首或句中时通常用逗号与主句隔开，位于句尾时可以不用逗号隔开。I will give you the information as soon as I get it.Once you start to smoke, it is hard to give it up.在时间和条件状语从句中，通常要用一般现在时表示将来意义
2、，而不能直接使用将来时态：Tell him as soon as he arrives. 他一来就告诉他。(不能用 will arrive)I wont go if it rains tomorrow. 要是明天下雨，我就不去。(不能用 will rain)有时也可见到 if you will 这样的说法，但那不是将来时态，而是表示意愿或委婉的请求(此时的 will 是情态动词)：If you will wait a moment, Ill fetch the money. 请等一下，我就去拿钱。状语从句即指在主从复合句中用作状语的从句。状语从句根据其用途可分为时间状语从句、地点状语从句、原因
