John is the only one of the students in the class who never _____ a mistake even when it is poi...

A

试题分析：考查固定搭配和动名词用法。固定搭配admit doing sth承认做某事；本题的先行词是the only one在句中做主语，谓语动词用单数的形式。固定搭配admit doing sth承认做某事；句意：John是班级里所有学生中唯一的承认犯了错误的人。本句话不需要死于完成式。故A正确。 点评：固定搭配admit doing sth承认做了某事；在日常的学习中要加强记忆这样的固定词组，关于动名词要注意它有名词的特征，作用相当于名词。
