Her class is so much fun?fan 和so much 在句中怎么解释?

"主语 ＋ be动词 ＋ so much " 是个固定表达的副词词组用法。意思是：XX 是如此地～；XX 是这么地～作用是：作为强调修饰前面的主语（这里的主语就是“Her class”）Her class is so much fun?她的课堂是那么地有趣。◎举几个类似句子的用法供你参考：He is so much attached to us。他和我们这样的要好。The news is so much music to our ears。这个消息真中听。There is so much for us to learn。我们要学的东西还有很多很多。
