我想在 Exam 类中避免问题和答案选项之间的分页符。对于如何避免答案选项内的分页符问题，有一个很好的解决方案这里，但该问题并未解决如何防止问题和答案之间出现中断。
答案1
添加以下行
\usepackage{etoolbox}
\BeforeBeginEnvironment{checkboxes}{\par\nopagebreak\minipage{\linewidth}}
\AfterEndEnvironment{checkboxes}{\endminipage}
到序言中提出问题，并将复选框放在一起。

答案2
由于\question不是环境，因此没有很好的方法在每个问题\minipage之前和之后插入。但before可以做得很好。正如\endminipage\filbreak\questionFrank Mittelbach 对另一个答案的注释，\filbreak插入低水平的拉伸（被克服\fill）和强烈的分页建议。如果 LaTeX 坚持在问题词干和其选项之间进行分页，minipage仍然可以在其周围进行硬编码。（注 1）
下一个挑战是该\question命令未在类的顶层提供exam。它仅在questions环境内。幸运的是，\questionshook提供了一个在此环境内扩展的命令。因此，将其放在序言中似乎可行：
\usepackage{etoolbox}
\appto{\questionshook}{\preto{\question}{\filbreak}}
这是一个完整的工作示例，可能不是最小的，但足够长，可以延伸到几页。（注 2）

笔记：
LaTeX 允许你将命令假装成环境。
\begin{question}启动一个组并扩展\question，并且（由于\endquestion未定义）\end{question}结束该组并且不执行任何其他操作。如果你喜欢使用环境，那么这很不错。
