这样就在每个小页面周围设置了 0.25 英寸的边距,使得小页面之间有 0.5 英寸的间隙。
\documentclass[twocolumn]{article}
\usepackage[margin=.25in, columnsep=.5in,noheadfoot]{geometry}
\usepackage{graphicx}
\usepackage{lipsum}% MWE only
\pagestyle{empty}
% set vertical gap to .5in
\newlength{\columnheight}
\setlength{\columnheight}{\dimexpr 0.5\textheight-.25in}
\setlength{\parindent}{0pt}% note that minipage resets these internally
\setlength{\parskip}{0pt}% so these only apply between minipages
\begin{document}
\begin{minipage}[c][\columnheight][t]{\columnwidth}
Top left.
\lipsum[1]
\end{minipage}\par% or just add a blank line
\vfill% add vertical gap between minipages
\rotatebox{180}{\begin{minipage}[c][\columnheight][t]{\columnwidth}
Bottom left.
\lipsum[2]
\end{minipage}}\par% LaTeX likes to break pages/columns between paragraphs
\begin{minipage}[c][\columnheight][t]{\columnwidth}
Top right.
\lipsum[3]
\end{minipage}\par
\vfill
\rotatebox{180}{\begin{minipage}[c][\columnheight][t]{\columnwidth}
Bottom right.
\lipsum[4]
\end{minipage}}\par
\end{document}
