it is more flattery than praise.这里more和than后不是加形容词/副词原级吗?怎么会是加名词和动词

这就有点象名言啦，看吧
这与其说是褒扬不如说是谄媚。
She is more a singer than an actress. 与 其说她是个演员，不如说是个歌唱家。 It was more a cross-examination than an interview. 与其说这是一次面试，不如说是 审讯。 It’s even more a poem than a picture. 与 其说它是一幅画，不如说是一首诗。

孩子这里的 flattery ,praise都是名词,不是所有more than 都接形容词副词.这里more flattery 还原成原级是much flattery ,就跟much water ,more water一样,many people,more people一样.不过这里flattery不可数名词,这样说能明白吗
