我目前正在使用考試班写下家庭作业考试的答案，但当我的答案太大而无法容纳一页时，我遇到了问题。我的论文中要么有很大的空白，要么答案溢出页面而无法进入下一页。所以我需要找到一种方法将答案\fbox分成多个框。
我不介意手动调整每个解决方案框的内容，但如果可以自动完成那就更好了。如果包含相同解决方案的框可以“开放式”，以显示它们属于同一类，我也非常喜欢。
为了完整起见，这里有一些额外的信息：
我尝试手动拆分解决方案，只是添加类似的东西，但
\end{solution}\newpage\begin{solution}无济于事。我也尝试阅读
exam.cls（我有版本 2.4，2011/05/22）以查看我是否可以自己破解它，并且看到一条评论（第 70 行）分页符实际上应该在解决方案环境中可用，但它们似乎对我来说不起作用。这个问题报告了同样的问题，但由于没有解决方案，而且我的评论可能不会引起任何关注，所以我决定重新发布重新表述的问题，包括以下 MWE：
\documentclass[a4paper,12pt,answers]{exam}
\usepackage{amsmath,amssymb,amsthm}
\begin{document}
\begin{questions}
\question Let $A \in \mathbb{R}^{n \times n}$, possibly singular. Show there exists $\epsilon \neq 0$ such that $A+\epsilon I$ is n.
\begin{EnvFullwidth}

\end{EnvFullwidth}
\end{questions}
\end{document}
非常感谢您的关注！
答案1
用它没有这
\begin{EnvFullwidth}
...
\end{EnvFullwidth}
或者定义一个\SetTotalwidth执行相同操作但允许分页的命令
\documentclass[a4paper,12pt,answers]{exam}
\usepackage{amsmath,amssymb,amsthm,lipsum}
\makeatletter
\def\SetTotalwidth{\advance\linewidth by \@totalleftmargin
\@totalleftmargin=0pt}
\makeatother
\begin{document}
\begin{questions}
\question Let $A \in \mathbb{R}^{n \times n}$, possibly singular. Show there exists $\epsilon \neq 0$ such that $A+\epsilon I$ is n.
\SetTotalwidth
\begin{solution}\noindent
\lipsum
\end{solution}
\end{questions}
\begin{questions}
\question Let $A \in \mathbb{R}^{n \times n}$, possibly singular. Show there exists $\epsilon \neq 0$ such that $A+\epsilon I$ is n.
\begin{solution}
\lipsum[5]
\end{solution}
\end{questions}
\end{document}
