该脚本使用Selenium自动化操作浏览器，实现以下功能：

1. 登录‘内蒙古开放大学’网站
2. 遍历所有待批改的题目
3. 统计每个题目对应的分值元素数量
4. 根据分值元素数量，随机对部分分值进行减分
   • 如果分值数量小于等于1，则随机减去1-2分
   • 如果分值数量大于等于1，则随机选择2-5个分值元素进行减分，每个元素随机减去1-2分

注意：

• 该脚本需要先安装Selenium库
• 在使用脚本之前，请确保已经打开了Chrome浏览器，并开启调试端口（例如：start chrome --remote-debugging-port=9222 --user-data-dir="D:\评阅用"）
• 脚本中的部分代码需要根据实际情况进行调整

使用该脚本需要谨慎，请勿用于恶意目的！
