【难点解疑】什么是状语？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。
