状语从句重难点讲解

状语从句重难点讲解经验案例：一、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,ourgrandparentswerepleasedtogetourphonecall.(副词)

2.Weworkedhard,fromsunrisetosunset.(介词状短语)

3.Tohelpmydisabledaunt,Ispendanhourworkinginherhouseeveryday.(不定式)

4.Seenfromadistance,thefarmhouselookeddeserted.(过去分词)

5.IknowhowtolightacampfirebecauseIhaddoneitbefore.（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。

二、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

1.状语从句的省略

状语从句同时具备下列两个条件:①主句和从句的主语一致，或从句主语为it；②从句主要动词是be的某种形式。从句中的主语和be动词常可省略。例如：

When(themuseumis)completed,themuseumwillbeopentothepublicnextyear.

He’llgototheseasideforhisholidayif(itis)possible.

2.时间状语从句中when的用法，一…就…的倒装和时态问题
