空格填not knowing,为什么?
____(not know)his telephone number,(接上)she had some difficulty getting in touch with Bill.空格填not knowing,为什么?
因为没有连接词.,原来前半句是原因状语从句,原句是 because she didn't know his……
去掉连接词,主语也省略,谓语变成非谓语knowing 当然助动词也没有了 那么否定词还原成not 就是not knowing了
本来应该是(because she don't ) know his telephone number 不过也可以用现在分词来引导原因状语。 所以是not knowing
就是-ing形式,因为是她不知道,可以还原成句子
Because she didn't know his telephone number, she had some difficulty getting in touch with Bill.
因为没有他的电话号码,她联系不上Bill
not knowing是现在分词作原因状语的用法,由于句子主语是she, 那么这个知道的动作就是she主动发出的,所以用现在分词not knowing
