如何调整答案环境以使其看起来像问题环境？

Question

我正在使用这些代码来生成我的试卷......

\documentclass[a4paper,addpoints]{exam}

\newbox\allanswers
\setbox\allanswers=\vbox{}
\def\qn{\question}

\newenvironment{answer}
{%
    \global\setbox\allanswers=\vbox\bgroup\large
    \unvbox\allanswers
}%
{%
    \bigbreak
    \egroup
}

\newcommand{\showallanswers}{{\begin{center}
\vspace{1cm}\large{\textbf{Class Test II(Test for Improvement)\\
Mathematics Foundation\\Answer Key\\
\hrule
%\\Sets and Relations, Matrices, Determinants \& \\Continuity and Differentiation
}}
\end{center}\par\unvbox\allanswers}}
% End Phil's answer

\begin{document}
\begin{questions}
\question First Question First Question First Question First Question First Question First Question First Question First Question First Question

\question Second Question

\end{answer}
\end{questions}
\showallanswers
\end{document}

通过这些代码我得到了这样的输出。

我的问题：

看看问题和答案，问题环境像枚举环境一样运行，但答案环境像手动一样工作。意思是说，我不想要答案中编号下面的单词。它应该像问题环境一样。就像这个图一样，

Answer 1

如果您希望这些答案的排版像枚举一样，那么最简单的方法是使用enumerate。

\documentclass[a4paper,addpoints]{exam}

\usepackage{enumitem}

\newbox\allanswers
\setbox\allanswers=\vbox{}

\newenvironment{answer}
{\global\setbox\allanswers=\vbox\bgroup\unvbox\allanswers
\begin{enumerate}[leftmargin=0pt]\item[\thequestion.]\ignorespaces}
{\end{enumerate}\egroup}

\newcommand{\showallanswers}{\par\bigbreak
\begin{center}
  \large\bfseries
  Class Test II (Test for Improvement)\\
  Mathematics Foundation\\
  Answer Key\\[1ex]
  \hrule
\end{center}
\unvbox\allanswers}

\end{answer}
\end{questions}

\showallanswers
\end{document}

我对你的代码的主要修改是答案的开头添加了

\begin{enumerate}
\item[\thequestion.]

最后加上结尾

\end{enumerate}

这样你就不必自己添加问题编号了。结果发现这给答案留下了很大的左边距，为了解决这个问题，我加载了enumitem并leftmargin=0pt在选项中设置了列表。这比使用低级 LaTeX 命令更容易。
