请分析一下这句话的语法结构，谢谢

这里是独立主格结构。
Time is one of the two elements that Americans save carefully,the other being labor(and the other is labor).

独立主格结构本身不是句子，在句子中作状语，表示时间、原因、条件、伴随等。常见的独立主格结构有如下几种：
1. 名词/主格代词+现在分词。名词/主格代词与现在分词之间主谓关系。如：
Time permitting (= If time permits), we will go for an outing tomorrow. 如果时间允许的话，我们明天去郊游。
2. 名词/主格代词+过去分词。名词/主格代词与过去分词之间的动宾关系。如：
The problems solved (= As the problems were solved), the quality has been improved. 随着问题的解决，质量已经提高了。
3. 名词/主格代词+不定式。名词/主格代词与不定式之间是主谓关系，且强调的是一次具体性的动作。如：
He is going to make a model plane, some old parts to help. 借助于一些旧零件，他要做一个飞机模型。
4. 名词/主格代词+形容词。如：
An air accident happened to the plane, nobody alive. 那架飞机遭遇了空难，无一人生还。
5. 名词/主格代词+副词。如：
The meeting over, they all went home. 会议一结束，他们就都回家了。
6. 名词/主格代词+介词短语。如：
The boy goes to the classroom, book in hand. 那男孩手里拿着书去教室。

如果表达的清楚一点便是：Time is one of the two elements that Americans save carefully,and the other is labor.
为了表达简练，句子用非谓语的形式表达了后一句。就成了the other being labor。
例如：There was nobody in the large room, so i felt scared.
There being nobody in the large room , i felt scared.

语法结构就是one.......the other
"一个是......另一个是............”
其中之一是"时间",另一个是"劳动力"

全句译为

时间是美国非常节省的两个要素之一,另一个就是劳动力

前面的that引导定语从句，即Americans save carefully修饰the two elements，由于一个句子不能有两个谓语动词，故后面不能用is而用being，作同位语。

Time is one of the two elements . Americans save the two elements carefully,the other being labor.

the other being labor. 本应该是: the other one of the two elements that Americans save carefully is labor. ,在这里,把这句当成了状语,所以要将系动词IS去动词化,就变成了BEING
