单选题 Scarcely ______ those words when suddenly the monster was transformed into a very handsome youth.
A. had he uttered B. did he utter C. he had uttered D. he did utter

【正确答案】 A
【答案解析】这道题是典型的否定副词提前的倒装结构，这类的结构有Hardly...when和No sooner...than。第二点要注意的是，当从句是过去时态时，主句应使用过去完成时。考生经常找对了倒装结构而忽视了时态的问题，平时一定要注意。
