Answer 1

您可以定义一个\makenonemptybox宏：

\documentclass[addpoints]{exam}

\newcommand{\makenonemptybox}[2]{%
  \par\nobreak\vspace{\ht\strutbox}\noindent
  \fbox{%
    \parbox[c][\dimexpr#1-2\fboxsep][t]{\dimexpr\linewidth-2\fboxsep}{
      \hrule width \hsize height 0pt
      #2
    }%
  }%
  \par\vspace{\ht\strutbox}
}
\makeatother
