问题补充：

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

答案：

A. one

(答案→)B. it

C. him

D. himself

解析：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。
