## 专家解析
### 【难点】
本句的难点在于括号中插入一个句子,而且从句数量也较多。解题的关键是找出从句。先不去管括号里面的东西,so that 表示“如此……以至于”,that 后面引导了一个结果状语从句。根据语义看,括号里面的句子相当于原因状语,表示主句的原因。Evidence 后面有个连接词 that, that 后面的从句成分是完整的,而且是对 evidence 的解释,解释证据是什么,所以 that 从句是同位语从句。
### 【子句拆分】
主句:However, the concept of number and the counting process developed so long before the time of recorded history.
状语从句1:There is chorological evidence.
同位语从句:Counting was employed by humans as far back as 50,000 years ago.
状语从句2:The manner of this development is largely conjectural.
### 【成分划分】
主句:However [状语], the concept of number [主语] and [连接词] the counting process [主语] developed [谓语] so long before the time of recorded history [状语]
翻译:但是,数字的概念和计算进程远在有历史记录之前就已经发展了。
状语从句1:There [表语] is [系动词] chorological evidence [主语].
翻译:有地域学的证据(存在)。
连接词:THAT
同位语从句:Counting [主语] was employed [谓语] by humans [状语] as far back as 50,000 years ago [状语].

连接词:SO THAT
状语从句2:The manner of this development [主语] is [系动词] largely [状语] conjectural [表语].
翻译:它发展的方式很大程度上是推测出来的。
### 【全句翻译】
但是,数字的概念和计算进程远在有历史记录之前就已经发展了(存在地域学证据表明五万年之前人类就已经运用计算了)所以它发展的方式很大程度上是推测出来的。
## 知识点梳理
