老师，这个that引导的是什么从句？

问题详情老师，这个that引导的是什么从句？ 老师回复问题同学你好，that the drama was a form of literature是一个宾语从句。整个句子可以这样划分：no boy who went to a grammar school/ could be ignorant that the drama was a form of literature/ which gave glory to Greece and Rome/ and might yet bring honor to England.翻译为：但凡读过文法学校的孩子都不会忽视戏剧这种文学形式,它曾经给希腊和罗马带来荣耀,并且还可能会给英国带来荣耀。that前为定语从句，which 后也为定语从句。
