请教各位专家：下面这个句子对吗？假如对，它的成分应怎么样剖析？主如果 we arrive there 是什么从句？是定语从句吗？引导它的词汇是什么？是被省略了吗？
The earliest we arrive there is about three days later.
▲The earliest we arrive there is about three days later.
= The earliest time that we arrive there is about three days later.
= The earliest time when we arrive there is about three days later.
1. we arrive there 是定语从句，先行词是The earliest ，省略了关系副词when 或that。
2. 不过，这个句子的时态有问题，应该是谈论过去的事情。建议改为：
The earliest we arrived there was about three days later.
▲除此之外，我还遇见另外一个句子，跟你的句子类似，但更复杂一些，跟网友推荐。
The closest that Herpin came to resting was to sit in a rocking chair and read some newspapers.
这个句子的核心是：comeclosetodoing意为“接近做某事”，引申为“可能做某事”。
本句close用最高级形式：comeclosesttodoing，“最可能做某事”。
【翻译】埃尔潘最大概的休息方法，是坐在摇椅上读报纸。
本句是一个特例：副词的最高级之前加 the，用作名词提到句首，如此that Herpin came to resting充当了定语从句。
