“注意look at之间可以插入一个方式状语，Look carefully at this. 但 look after之间不能插入方式状语：Look after the baby carefully.”

在上面中look at分析为动状，look after整体分析为短语动词，不能插入方式状语。

然而在词典中：depend on/upon [phrasal verb]

depend on/upon (someone or something)

: to need (someone or something) for support, help, etc.依赖；依靠

 They depend heavily/largely/solely/entirely on her income to pay the bills. [=without her income they would not be able to pay their bills]他们在很大程度上/仅仅/完全依靠她的收入来支付账单。

depend on/upon被词典里列为短语动词，但是例句中间为什么却可以插入heavily/largely/solely/entirely呢？depend on仍分析为短语动词还是动状结构？
