            <h1>欢迎使用U校园学习时长脚本</h1><br>
            <h2>U校园学习时长计分规则：</h2>
            <p>学习时长大于等于20小时得满分；小于等于0小时不得分；学习时长在0小时至20小时之间，得分为学习时长/20*100*20%。</p>
            <h2>U校园学习时长统计规则：</h2>
            <p>各必修Task学习时长相加后的累计时长。PC端和App端同时在线学习时，系统只记录其中最近活跃一端的学习时间。</p>
            <h2>脚本使用方法：</h2>
            <p>打开U校园对应必修学习章节后挂机即可，本脚本会定时翻滚页面，防止出现“长时间未操作”而导致的学习时间无法计入的情况。</p>
            <h2>注意：</h2>
            <p>※本脚本目前仅支持U校园Reading comprehension和Reading in detail两个模块的挂机，二者任选其一即可。
            <br>※挂机时请勿最小化浏览器，防止脚本失灵。</p>
