It is not unusual to act as if owning all that is the very latest and most expensive is a sure way to happiness.

【翻译】表现出似乎拥有一切最新潮、最昂贵的东西，才是一条通往幸福的必由之路，这不足为怪。

【分析】as if owning all that is the very latest and most expensive is a sure way to happiness，是act 的方式状语。

1. owning all that is the very latest and most expensive：动名词短语作主语。

2. 在上面的动名词短语中，包含一个定语从句that is the very latest and most expensive，修饰all。owning all that...“拥有一切”，that 定语从句说明了“什么的一切”。

3. is a sure way to happiness：系表结构。to happiness 作定语修饰way。
