Question

英语语法问题请教。。。谢谢了？

请大家帮忙分析一下这句话的成分和结构（越细越好），谢谢大家。
As if this were not enough to reduce you to tears, your husband arrives, unexpectedly bringing three guests to dinner.
好像这一切还不足以使你急得掉泪，你的丈夫接着回来了，事先没打招呼就带来3个客人来吃饭。

Answer 1

as if 引导的让步状态从句好像……，your husnand artives ,主谓结构，是主句。unexpectedly bringing three guests to dinner 动名词短语作伴随状语。

Answer 2

As if this were not enough to reduce you to tears状语从句, your husband主语 arrives谓语, unexpectedly状语 bringing three guests to dinner状语.
As if引导词 this主 were系 not enough表 to reduce you to tears状语
