修改如下：

  1. 添加中英文语言资源文件，命名为lang_zh_CN.properties和lang_en_US.properties。

  2. 修改main方法中的语言选择和输出内容，使用ResourceBundle类获取对应的语言资源文件，并根据语言选择输出对应的内容。

  3. 在Question类中添加中英文资源文件，修改toString方法，使用ResourceBundle类获取对应的语言资源文件，并根据语言选择输出对应的内容。

  4. 修改register方法中的输出内容，使用ResourceBundle类获取对应的语言资源文件，并根据语言选择输出对应的内容。

  5. 修改startQuiz方法中的输出内容，使用ResourceBundle类获取对应的语言资源文件，并根据语言选择输出对应的内容。

修改后的代码如下：
