选择题
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
答案：B
题目分析：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。
