修改代码功能：到最后一个学生以后，还能重新启用打分功能，避免重复的去开始运行，写出需要修改的代码和需要修改的位置内容：需要修改的代码：

在 stop_program 函数中添加以下代码，以重新启用打分功能：

self.start_score_button.config(state='normal')
self.start_score_button_2.config(state='normal')
self.start_forum_button.config(state='normal')

在 score_program_100、score_program、forum_score_program 函数中添加以下代码，以判断是否到达最后一个学生：

if "已经到最后一个学生" in self.browser.page_source:
    self.update_running_label('已到最后，请手动保存后重新开始！')
    break

需要修改的位置：

stop_program 函数的最后
score_program_100、score_program、forum_score_program 函数的 while True 循环中的最后一个 else 分支中
