13.Not until his parents criticized him to realize his mistake.( )A. | does Tom begin | B. | did Tom begin | C. | Tom began | D. | had Tom began |
分析 直到Tom父母批评了他,他才开始意识到他的错误.
解答 答案:B.
分析句子结构可知,本句为not until位于句首,可知,后面的句子谓语部分要用部分倒装的结构,可排除C;时间状语从句中的时态criticized为一般过去时,所以主句的时态也应该是一般过去时,可排除A和D;故选B.
点评 对于倒装句式要熟练掌握几种基本的结构,灵活运用部分倒装和全部倒装的用法.
