【题目】After a talk with his mother, the little boy has seen to _____ that the same mistake doesn’t happen again．
A. one B. it C. him D. himself
在线课程【答案】B
【解析】试题分析：本题中的it是特殊用法，本题的it北称为模糊it，在句中没有意思，但是不能省略。如I hate it when it is hot。我讨厌天气太热。本句的it和例句的it是同一个用法。See to it that….务必做到…保证…。句义：和妈妈谈话以后，这个小男孩保证同样的错误不再发生。故B正确。
