Question

Knowing office rules—whether______or not—is critical,especially for young job seekers.
A．written \x05B．writing
C．being written \x05D．having been written
A　考查非谓语动词.句意：懂得职场规则是很关键的,不论该规则是不是写成文字的,尤其是对年轻的求职者.whether后省略了office rules are,因此用过去分词.我想问的是句子结构,whether在这里引导一个什么句子,

Answer 1

whether引导条件状语从句,只是这里是省略形式,省略了office rules are,这里whether or not 也是whether的固定短语
