非谓语5
______of his name,we had a lot of trouble in finding the patient. A.Not informed B.Not having informed C.Not having been informed D.Having not informed 应该选C，可是我觉得是省略的主语we主动记录他的名字呀...怎么解释呢？
______of his name,we had a lot of trouble in finding the patient. A.Not informed B.Not having informed C.Not having been informed D.Having not informed 正确答案:C 译文:由于没有被告知他的姓名,我们要找到这个病人费了很大的力气. 解析:we"我们"是这个句子的主语,"we我们"和 "inform告知"之间存在被动关系,所以用被动语态,前面部分是后面部分的原因,而且发生在后面一个句子谓语动作之前,所以我们用现在分词的完成式来表示,作原因状语.
单选我先选C， C和A的区别在于：C在强调非谓语动词在中心谓语动词之前发生。
______of his name,we had a lot of trouble in finding the patient. A.Not informed B.Not having informed C.Not having been informed D.Having not informed 应该选D.因为，这里的原句应该是Because we had not informed of his name ,...。这样才主谓一致。而C项是被动语态，原句很难恢复出来，所以，问题较大。
其实,A和C没有大区别,这两个答案都对.
