About This Practice关于本训练系统

Historic Dates trains memory athletes to associate fictional historical events with four-digit years. The events are fictional and do not require historical knowledge.本训练通过将虚构历史事件与四位数年份建立联系，训练选手的关联记忆能力。事件均为虚构，不需要真实历史知识。

Each practice randomly selects 100–500 Chinese events from a fixed bank of 5,000 and pairs them with unique random years from 1000 to 2026. Memorisation and recall each show 100 events per page; recall order is shuffled again.每次从固定的5000条中文事件题库中随机抽取100—500条，随机配对1000—2026年之间不重复的年份。记忆和回忆均每页显示100条，回忆时再次打乱事件顺序。

Correct answers earn one point, incorrect answers deduct half a point, and blanks score zero. The final score is rounded up, with a minimum of zero. All answers can be reviewed after practice.答对一条得1分，答错一条扣0.5分，未填写得0分；最终得分向上取整且最低为0分。训练结束后可核对全部答案。
