请帮我看一下这个英语考研真题翻译：这个句子成分是怎样的，请英语高手帮我看看：

Question

Since our chief business with them is to enable them to share in a common life we cannot help considering whether or not we are forming the powers which will secure this ability.

这句“we cannot help considering whether or not we are forming the powers which will secure this ability. ”这在句子是什么成分？谢谢你！
在新东方的真题解析中，是这样说的：其实这是两个不同的句子，加上一个逗号就容易理解了，
Since our chief business with them is to enable them to share in a common life ，we cannot help considering whether or not we are forming the powers which will secure this ability.
是这样的话，考试中心真能出题。

Answer 1

这是一个复合句。Since our chief business with them is to enable them to share in a common life 是since引导的原因状语从句，we cannot help considering whether or not we are forming the powers which will secure this ability是主句，其中which will secure this ability是定语从句，修饰先行词powers。

因此，断句如下：

Since our chief business with them is to enable them to share in a common life既然我们的主要任务在于使他们参与共同生活；

we cannot help considering whether or not we are forming the powers我们禁不住考虑我们是否在形成这种力量；

which will secure this ability获得这种能力的。

句子翻译：

既然我们的主要任务在于使他们参与共同生活，我们禁不住考虑我们是否在形成获得这种能力的力量。

Since our chief business with them is to enable them to share in a common life 原因状语从句
we cannot help considering whether or not we are forming the powers which will secure this ability. 原因状语从句的主句
whether or not we are forming the powers which will secure this ability 为cannot help considering 宾语从句
which will secure this ability 为powers的定语从句
