我们知道，形容词是用来表示人或事物的属性或特征的一类词，用来修饰名词或代词，在句子中主要可以用作定语、表语和补语。例如：

（1）用作定语：This is an interesting book. 这是一本有趣的书。

（2）用作表语：This book is interesting. 这本书很有趣。

（3）用作补语：We found this book interesting. 我们发现这本书有趣。

在例（3）中，单个形容词（interesting）作宾语（this book）的补语。而除了单个形容词，很多形容词词组也可以可以作补语。我们今天就来认识一下，有哪些形容词词组可以作补语。它们主要有以下几类：
