副词作状语通常修饰动词,有时修饰整个句子.程度副词作状语则修饰形容词或副词,作程度状语.副词作状语常表示事情发生的时间、地点、方式、条件、原因,或者表示让步、程度等.（例子就省了吧.）
形容词充当状语多表示主语的状态.如：
The man was lying on the ground,dead.
He came back home,tired and hungry.
After hours of walking,she arrived home safe.
Mr Black came back drunk that night.
以上句子中的dead,tired and hungry,safe,drunk都是形容词充当状语,它们都表示主语的状态.形容词的这种用法也有人认为不是充当状语,而是主语补足语.
