英语鸭是一款专注输入式记忆的英语词汇 App。每天 20-50 个单词的固定学习量,配合透明的复习节奏,让你既能坚持,也不会被复习债务压垮。 为什么是输入式? 被动看选择题、点出正确答案——记得快,也忘得快。逼自己亲手把单词拼出来,调用主动回忆,这是认知科学里反复验证的「真正在学」的姿势。 核心特色 • 输入式练习:让你拼出来,而不是只认出来 • 透明的复习节奏:基于掌握等级(脆弱→熟悉→稳固→精通)与间隔规则,不靠复杂模型,但严谨可查 • 同日回炉:当天答错的词,今天再练一轮巩固 • 固定每日量:20 / 30 / 50 词三档计划,按自己节奏来 • 个性化难度:根据你在每个词上的真实表现自动调整复习时机 • 进度可视:掌握分布、层级进度、学习趋势一目了然 • 单词发音:答题后自动播放,听写一体 适合谁 • 想为四六级、考研、雅思、托福扎实打底的同学 • 工作日想持续提升英语词汇量的成年学习者 • 自学打卡过、但被复习累计压垮过的人 不会做的事 不主打游戏化排行榜,不卖课,不放广告,不要求通讯录或位置权限。专心做好一件事——把单词记住。 每天 10 分钟,词汇量在复利里慢慢长起来。
