如何分析这句话的语法结构?谢谢It is possible we are unconsciously sending m

It形式主语 is系动词 possible表语 we are unconsciously sending messages with every action,messages that are unconsciously picked up by others and used in forming opinions.实际主语；
实际主语中,we主语 are unconsciously sending谓语 messages宾语 with every action,messages状语 that are unconsciously picked up by others and used in forming opinions（前面sending messages 中messages的）定语从句.
定语从句中,that主语 are unconsciously picked up谓语 by others状语 and used并列谓语 in forming opinions状语
翻译：我们正在不知不觉中通过每一个行为、信息发出信息,这些信息正不知不觉的被其他人接收到并被用于改变他们的观点.

主句：It is possible +（that 从句）. It做形式主语
从句1：that 从句，是整句的真实主语，其内部主干是we are doing sth。
逗号后的messages到最后是前面的messages的同位语。
从句2：定语从句，同位语messages后面that引导的部分，用来修饰messages。其内部主干是 ...

前面是it is possible （that）+一个句子，后面是补充逗号前message，that定语从句啊…

it代指“潜意识无意识发送的行为和信息被他人在形成观点的过程中无意识的接收”--结构it is possible +that从句。从句结构：sth was pickup and used in forming opinion(unconsciously).
