He should be wiling to work on his own,often at high speeds,but should be humble enough to consult others______his own knowledge not always prove adequate to the task in hand.
A.should B.when C.because D.if
为什么不能选其他三项,最好能说一下如果要选B/C/D 句子要怎么改,
第一个should,是“竟然”的意思
第二个should,是本义,应该
第三个should,是助动词,没意思的,作用是帮助构成虚拟,而且是将来的虚拟
本来应该是if his his own knowledge should not be always prove adequate to the task in hand.
表示将来的情况,变成省去if 的虚拟条件句,以部分倒装（疑问句的形式）出现
这种结构比原来if引导的从句要正式
再问： if his his own knowledge should not be always prove adequate to the task in hand. =should his own knowledge not be always prove adequate to the task in hand. 原句should his own knowledge not always prove adequate to the task in hand.没有be 啊
再答： should prove ,多打了个be
再问： 为什么不加be呢，不是被动吗
再答： prove这个词是系动词，不用被动的 It proves right
