关于until的使用方法

And I know that if we put our heads and our hearts into this company,we will deliver, I know that. Now, I love challenges. I love hard work. I look forward to sitting at this very table tossing ideas around until what I fear will be the wee hours of the morning. But most importantly, I want the work we do to say something about who we are, how we think, what we feel. So, as our friends in Hollywood say, “Let’s cut to the chase.”How are we gonna turn this company around?

这里的until是修饰谓语动词look forward to 还是非谓语动词sitting 还是tossing around？ 我该怎么分辨？ 另外这个until后跟的是个名词还是句子？我判断不出until在这里是介词还是连词，提前感谢各位老师，第一天注册，还没鲜花，深表歉意!

I look forward to sitting at this very table tossing ideas around until what I fear will be the wee hours of the morning.

1. 本句，until 是连词，引导的是时间从句，是一个“主系表结构”。不是介词。

2. what I fear （主语）will be （系动词）the wee hours of the morning（表语）：我担忧的事儿是凌晨时分的到来。

3. tossing ideas around（反复考虑），目前分词作 sitting 的随着状语。

4. 关于until 从句，到底是修饰谓语动词look forward to，还是目前分词sitting，还是 tossing around，这需要依据语义判断。

（1）look forward to 表示，期待的结果是 sitting，该动作到 sitting 即结束，所以 until 不是修饰 look forward to。

（2）until 从句应该同时修饰 sitting 和 tossing 两个动作，它们是同时进行的，而且是持续的。

【翻译】我期待着坐在这张桌子旁，反复思量，沉思冥想，直到我担忧的凌晨时分的到来为止。
