/*  ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
*  优学院自动静音播放、自动做练习题、自动翻页、修改播放速率脚本v1.6.1由EliotZhang @ 2020/06/04 最后更新
*  特别感谢Brush-JIM (Mail:[email protected]) 提供的脚本改进支持！
*  使用修改播放速率功能请谨慎！！！产生的不良后果恕某概不承担！！！
*  请保持网课播放页面在浏览器中活动，避免长时间后台挂机（##有挂机检测功能），以减少不必要的损失
*  自动作答功能由于精力有限目前只支持单/多项选择、判断题、部分填空问答题，如果出现问题请尝试禁用这个功能!
*  如果脚本无效请优先尝试刷新页面，若是无效请查看脚本最后的解决方案，如果还是不行请反馈给本人，本人将会尽快修复
*  如果是因为网络问题，本人也无能为力
*  如果在使用中还有什么问题请通过邮箱联系EliotZhang：[email protected]
