摘要：放在宾语后面作宾语补足语， 例如，We should keep our dormitory clean every day。
一.形容词一般用法：作定语、表语、宾语补足语
形容词在句中常见的用法是：
修饰名词或代词作定语，例如，A beautiful girl ；
放在系动词后面作表语，例如，The dish tastes delicious；
放在宾语后面作宾语补足语， 例如，We should keep our dormitory clean every day。
像这样这样句子“The man spent five days in the heavy rain, hungry and cold”，在这个句子中“hungry and cold”，很明显这词组在这个句子中既不是作定语、表语，也不可能作宾语补足语，而类似这样的句子，大家经常在阅读文章中碰到，但不知道形容词在这样类似的句中作用与功能。其实上面这句话“The man spent five days in the heavy rain, hungry and cold”中的形容词“hungry and cold”在句中作状语修饰动词“spent”，“又冷又饿地度过了五天”。又如，Everybody is created equal (人生来就是平等的，这里形容词equal修饰create）。实际上高考中已经出现了类似考点。

形容词或形容词短语作状语的前提条件是表达主语的状态，否则形容不能用于作状语
例如，

注意：上面这两句中的tired and hungry，safe,都在句子中作状语，都表达主语的一种状态。
