单选题
As regards to the development of moral standards in the growing child, ______ is very important in parental teaching. To forbid a thing one day and excuse it the next is no foundation for morality.
【正确答案】
C
【答案解析】[解析] 名词词义辨析。persistence“坚持不懈；持续，留存”；regularity“规律性，规则性；整齐”；consistency“一致性，连贯性”；conformity“依照，符合，一致”。根据句中excuse it the next提供的信息，是指“父母教育的一致性很重要”。故答案为C。
