为多项选择题创建新环境

Question 1

我是否可以建议exam 文档类？

示例文件：

\documentclass{exam}

\usepackage{lipsum}

\printanswers

\firstpagefootrule % Use a footer rule on the first page
\runningheadrule   % and so on
\runningfootrule   % and so on (note that this does not cancel out \firstpagefootrule

% define the header for the first page (left, center, right), and so on
\firstpageheader{MATH 351 -- Analysis}{\large \sc Fall 2012 Midterm}{\today}
\firstpagefooter{}{\thepage\ of \numpages}{}
\runningheader{MATH 351 -- Analysis}{Fall 2012 Midterm}{\today}
\runningfooter{}{\thepage\ of \numpages}{}

\begin{document}
Read each question carefully. % Preliminary instructions
\begin{questions}
    \question[50] How long should a man's legs be? % This question is worth 50 points
        \begin{solutionorlines}[1in] % If \printanswers is specified,
                                     % the solution will be printed.
                                     % Otherwise, a box 1 inch tall
                                     % will be printed instead.
            Long enough to reach the ground!
        \end{solutionorlines}
    \question[$\infty$] \lipsum[1]   % arbitrary symbolic point values
        \begin{equation}
        \int_0^{2\pi} \sin x\ \mathbf{d}x
        \end{equation}
        \begin{solutionorbox}[2in]
            \lipsum[2]
            \begin{equation}
            \int_0^{2\pi} \sin x\ \mathbf{d}x = 0
            \end{equation}
        \end{solutionorbox}
\uplevel{\lipsum[1-2]} % Perhaps a different part of the exam? More instructions?
\newpage
    \question \lipsum[4]
        \begin{parts}
            \part[10] \lipsum[5]
                \begin{solutionorbox}[2in]
                    \lipsum[10]
                \end{solutionorbox}
            \part[15] \lipsum[6]
                \begin{solutionorbox}[2in]
                    \lipsum[12]
                \end{solutionorbox}
        \end{parts}
\end{questions}
\end{document}

产生留有答案空间的文件，而添加\printanswers到序言中将产生相同的文件，但打印了答案。如果您想要自定义问题标签（而不是简单的增量），我为此编写了一些新命令：

% for the `exam` class
\newcommand{\xquestion}[1]{
    % Set the questionlabel to the user's choice
    \renewcommand{\questionlabel}{#1}
    \question % do the question thing
    % and reset it back to default
    \renewcommand{\questionlabel}{\thequestion.}
}
\newcommand{\xpart}[1]{
    % Set the partlabel to the user's choice
    \renewcommand{\partlabel}{#1}
    \part % do the part thing
    % and reset it back to default
    \renewcommand{\partlabel}{(\thepartno)}
}

与往常一样，文档类的完整文档位于CTAN。

希望这可以帮助！

Question 2

我认为在这种情况下（考虑到您的输出），使用标准enumerate环境最容易。可以使用以下方法操作/更改可能的对齐或计数器格式/交叉引用enumitem，如有必要：

在此处输入图片描述

\documentclass{article}
\usepackage{enumitem}% http://ctan.org/pkg/enumitem
\usepackage{lipsum}% http://ctan.org/pkg/lipsum
\begin{document}
\begin{enumerate}[label=\arabic*.]
  \item \lipsum[1-2]
  \item \lipsum[3-4]
  \item \lipsum[5-6]
\end{enumerate}
\end{document}

lipsum以段落形式提供一些虚拟文本，乱码风格。

优点：

可通过以下方式轻松修改enumitem；
跨越页面边界的分页；以及
标准接口/使用。

question对于全局采用专门创建的模拟/克隆的环境enumerate，enumitem的界面提供：

\newlist{question}{enumerate}{3}% Clone enumerate as question environment (depth of 3)
\setlist[question]{label=\arabic*.}% All labels are "\arabic."

现在您可以使用

\begin{question}
  \item \lipsum[1-2]
  \item \lipsum[3-4]
  \item \lipsum[5-6]
\end{question}

有关详细信息，请参阅enumitem文档（部分7 克隆基本列表，第 10 页）。
