★请大家举例状语:
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。
★复合句之一 状语从句（Adverbial Clause，在句子中起状语作用的从句）。状语从句根据它在句子中的作用分为：时间状语从句、条件状语从句、地点状语从句、原因状语从句、目的状语从句、让步状语从句、结果状语从句和比较状语从句。判断下列句子的类型：
1．I fell asleep when ( as , while ) he was doing his exercises . 他正作练习时我睡着了。（时间状语从句）
2．Where there is a will，there is a way . 有志者，事竟成。（地点状语从句）
