along...with采用的是就远原则。
就远原则也叫就前原则，具体就是:主语后有with,together with,along with,except,besides, as well as等介词或介词短语时，谓语动词的数和人称要与这些词或短语前面的名词的单复数保持一致，也就是就前原则，也即和离谓语较远的名词决定。
例如: Mr. Green together with his children goes to the park every Sunday.
谓语动词之所以用goes,因为离他远的名词，或者说在together with之前的名词为Mr. Green,主语为三人称单数，所以谓语用goes.
若交换顺序，成下面的句子，谓语又不一样了:
His children together with Mr. Green go to the park every Sunday.
其实这个原则的原理是因为with, along with等词和短语为介词或介词短语,后跟的名词只能是介宾结构,不可能充当主语。
