They did not find ____?to prepare for the worst conditions they might meet.
A.worth their while
B.it worthwhile?
C.it worth
D.it worthy
句意:他们发现为可能遇到的最差的条件做准备是不值得的.
为什么不选d 呢.worthy后面也可以跟to do.如：He said he was not worthy to accept such honour .

首先,worthy确实可接不定式to和介词of,但要注意,其搭配为“be”worthy to及“be”worthy of
题中的it为形式宾语,真正宾语为不定式短语to prepare for the worst conditions they might meet,worthwhile为补语.
若要用worthy,那么应表达为：
They did not find it a worthy thing to prepare for the worst conditions they might meet.
此时a worthy thing 做补语.
