Step Ⅰ: 状语从句的定义及分类
比较以下句子
1. I used to carry some water for him three years ago.(有一个主谓结构和时间状语,简单句)
2 When I lived in the countryside, I used to carry some water for him (从句为时间状语从句,表示整个句子的时间,复合句,连接词为when)
3. Don't drive so fast,or/otherwise you'll have an accident.(有并列连词or/otherwise为并列句)
4. You can use my bike on condition that you return it by Friday.(______句,连词________)
5. We’ll make a trip even if/though the weather is bad. (______句,连词________)
小结:有连接词连接两个及两个以上的句子统称为复合句,从句修饰主句中的谓语动词、形容词、或副词的为状语从句。按照所作的状语和意义可分为时间、地点、原因、目的、结果、条件、让步、方式和比较等九种状语从句。
