九大状语从句50大连词

   状语和状语从句

   状语修饰动词、形容词、副词或整个句子。通常由副词、介词短语、动词不定式、分词和从句等担当。例如：
      1. Naturally , our grandparents were pleased to get our phone call . (副词)
     2.  We worked hard , from sunrise to sunset . (介词状短语)
     3.  To help my disabled aunt , I spend an hour working in her house every day .(不定式)
     4.   Seen from a distance , the farmhouse looked deserted . (过去分词)
     5.  I know how to light a camp fire because I had done it before .（原因状语从句）
    状语的位置比较灵活，可以位于句首、句末或句中。enough用作状语修饰形容词和副词时必须后置。

    状语从句主要用来修饰主句或主句的谓语。一般可分为九大类，分别表示时间、地点、原因、目的、结果、条件、让步、比较和方式。尽管种类较多，但由于状语从句与汉语结构和用法相似，所以理解和掌握它并不难。状语从句的关键是要掌握引导不同状语从句的常用连接词
