前言
该代码实现了一个基于PyQt5的单词记忆软件，支持高考、四级、六级和考研四个级别的词库。程序提供四种学习模式：拆分模式（将单词拆分为片段重组）、填空模式（选择正确字母填空）、输入模式（手动输入单词）和测试模式（评估单词记忆效果）。软件界面包含单词释义显示、交互练习区域和反馈功能，支持单词级别切换、结果统计和保存功能。采用随机算法打乱单词顺序，确保学习效果，具有错误提示和自动跳转下一题功能，适合不同英语水平的学习者使用。
目前存在的问题和优化思路，目前还没实现：
- 拆分模式再次点击已经被选择的单词片段可以取消锁定，但是要按单词拼写的倒序取消（原本是没锁定的，但是那样会导致一个字符可以重复点击，导致单词拼接不正确，而且还没法判断正误）。
- 模式之间切换会导致窗口卡死，这个还没找到是什么原因。
- 测试模式可以结合其他三种模式来进行选择。
- 当保存的时候点击那个词书就会保存什么，比如我是测试的"高考"，但是在保存的时候点击了"考研"，保存名字默认是"考研"。
- 单词太少了，完全是deepseek生成的，自己目前还没看到错误的，也可以是因为本人英语不好所以还没发现。
拆分模式
- 显示单词的释义
- 将单词拆分成若干片段并打乱顺序显示
- 用户按正确顺序点击片段拼出完整单词
- 系统检查是否正确，提供反馈

self.correct_word = word
self.user_answer = ""
填空模式
- 显示单词的释义
- 显示带有空缺的单词（部分字母被下划线替代）
- 提供4个选项（1个正确，3个干扰项）
- 用户选择正确选项填补空缺
- 系统检查是否正确，提供反馈

self.mode2_options_layout.addWidget(btn)
self.option_buttons.append(btn) # 保存按钮引用
输入模式
这个当时最大的问题就是那个错误信息和文本信息没有清空，导致再次输入还可以看到提示信息，那岂不是可以照着输入。
- 显示单词的释义
- 用户输入框中输入对应单词
- 系统检查是否正确，提供反馈
- 可回车提交答案

测试模式
- 点击"开始测试"按钮
- 系统随机选择词库中的单词
- 显示单词释义，用户输入对应单词
- 记录错误次数
- 测试完成后显示统计结果（正确率、错误最多的单词等）
- 可保存测试结果到文件
