在逐字文本上叠加红色矩形

我正在使用 Beamer 准备演示文稿。我需要在某张幻灯片中打印大量逐字文本，还需要在其上绘制一些红色矩形。

最直接的方法是什么？ 我正在为 fancyvrb 和 tikz 而苦苦挣扎。

\documentclass[pdf]{beamer}
\usepackage{semiverbatim}

\begin{document}

\newsavebox\myv
\begin{frame}[fragile]

\begin{lrbox}{\myv}\begin{minipage}{\textwidth}

这是我希望图像显示的方式（请注意红色矩形）：

有一种可能性是：

\documentclass[pdf]{beamer}
\usepackage{listings}
\usepackage{tikz}
\usetikzlibrary{tikzmark}

\lstset{
  basicstyle=\ttfamily\small,
  columns=fullflexible,
  escapeinside={/@}{@/}
}

\newcommand\DrawBox[2]{%
\begin{tikzpicture}[remember picture,overlay]
\draw[red] 
  ([yshift=1.7ex,xshift=-2pt]pic cs:#1) rectangle ([yshift=-.25ex,xshift=2pt]pic cs:#2);
\end{tikzpicture}%
}
\begin{document}

我们的想法是切换到listings包，因为它可以逃逸到 LaTeX，然后使用该tikzmark库在适当的位置放置一些标记；然后使用这些标记使用简单的\DrawBox命令来绘制框架；该命令的两个参数是每个框的开始和结束标记。

该代码需要运行两到三次才能稳定下来。

答案2

这里我使用verbatimbox包将逐字内容放在一个框中，以\scriptsize适合页面大小。然后我使用 3 个嵌套的\stackinsets 将红色矩形放在其上。
