问题描述：
It has long been known that the hunting scenes depicted on walls were not simply a form of artistic expression.
麻烦讲解下为什么后面还有个were谓语 句子不久有2个V了吗
答
首先整个句子是it做形式主语，真正的主语是that the hunting scenes depicted on walls were not simply a form of artistic expression.
其次that the hunting scenes depicted on walls were not simply a form of artistic expression.
中，depicted on walls 是定语，修饰the hunting scenes
答
这里that引导了一个宾语从句
所以也是一个句子
答
不是两个谓语.the hunting scenes depicted on walls were not simply a form of artistic expression.
depicted on walls 是过去分词短语做定语修饰scenes
