形容词最主要的功能是修饰名词，充当定语。形容词还可以作表语和宾补，如 ：
make sb angry,
leave sb homeless,
sb find it difficult/hard to do sth.
Sth make it possible for sb to do sth.
其实，形容词作状语的用法也是不少见的，多用来表达人物的心理状态。有人也称之为主语补足语，因为它们是补充说明主语的。掌握好以下两个句型，必将极大地助力于读后续写!
句型一:
主谓等……(简单句)，+形容词(短语).(与全句用逗号隔开，位于句子后面)

(Jane 起身时的状态是“又饿又渴”。为了表达这种状态，该句使用了形容词短语 hungry and thirsty 作伴随状语。)

He lay in bed and he was awake
