What first seemed like a luxury的句子成分分析

问题描述

What first seemed like a luxury, crawling from bed to computer, not worrying about hair and  clothes and face, has become an avoidance, a lack of discipline. 

译文：开始时让人觉得这是一种享受生活——从床上爬到电脑前，不必顾忌发型、衣服以及表情，后来逐渐成为一种回避，一种懒散。

我的疑问：What first seemed like a luxury 中的句子成分分析是怎样的？请老师指教，谢谢！

老师答疑

黎老师：

What first seemed like a luxury = The thing that first seemed like a luxury ，后面的 crawling from bed to computer, not worrying about hair and clothes and face 表示 a luxury 的具体情况。 that first seemed like a luxury 是定语从句，修饰 The thing。可以把 What first seemed like a luxury 看作主语从句，在该主语从句中， What 是主语，seemed 是系动词， like a luxury 是介词短语作表语。
