Question

以下这个句子是什么意思?
He should be willing to work on his own,often at high speeds, but should be humble enough to consult others should his own knowledge not always prove adequate to the task in hand.
第二个should在句中是什么意思？

Answer 1

这是should带有虚拟语气用法的一个倒装,实际上是if引导的条件状语从句
原句是 He should be willing to work on his own,often at high speeds,but should be humble enough to consult others,if his own knowledge (should) not always prove adequate to the task in hand
