She with her parents is going there 这里的介词后不能作主语 为什么Listening to music is good 可以做

listensting to music 是固定搭配 做主语
she with her parents 强调主语she

这个句子的主语是：She with her parents....
但谓语动词的“数”与最远的 She 保持一致，这只是语法规则。
She with her parents is....
= Her parents with her are....(Her parents ....are...)
She and her parents are...(A and B + are...)
Listening to music is....不是介词 to 在做主语，而是整个动名词短语: Listening to music

介词永远不可以做主语.这个句子的主语是：She with her parents.但谓语动词的“数”与最远的 She 保持一致,这只是语法规则.She with her parents is.= Her parents with her are.(Her parents .are...)She and her p...

第一句with her parents 是状语。此句可以理解为：She is going there with her parents 。
第二句：Listening to music is good ，是动名词做主语，不是介词，只能说：此短语中，to是介词。
