be meant to be doing如何分辨是不定式是进行时还是系表结构

I was meantto be workingon Sunday, but I just fooled around all day.

We are meantto be operatingas team.

我不了解以下问题提的对不对：

问题1：当看到to be doing时，除去是不定式的进行式，这里的be有没可能是系词，然后doing是动名词或分词？如何分辨？

问题2：meant也可以是形容词，那I was meant 和we are meant是被动语态还是系表结构？如何分辨？

I was meantto be workingon Sunday, but I just fooled around all day.

We are meantto be operatingas a team.

be meant to do 应该做；照理该做，按规矩该做

网友考虑得过于复杂。黑体部分，都是不定式的进行体，跟一般体没太大差别。其他不需要考虑。
