题目

With a local guide _____ the way ,they had no trouble ___ out of the forest.
With a local guide _____ the way ,they had no trouble ___ out of the forest.
A.leading;walking B.led:walked C.lead:walking D.leads;walking
我选的是A,请说明理由.第一个空可以填 to lead 请详细说明理由

答案

对的.第一句是with 的复合结构,with加不定式表示的是将要进行的事情,而从句意来看明显是已经发生过的.with接分词形式表示主动（ing）或者被动（-ed）,这里面是导游主动引导,所以leading;后面半句是had no brouble in doing sth,其中in可以省略,表示:做什么事情毫不费力.
