您可以手动添加这样的块
\documentclass{beamer}
\usetheme{Warsaw}
\begin{document}
\begin{frame}
\begingroup
\centering
\begin{beamercolorbox}[sep=12pt,center,colsep=-4bp,rounded=true,shadow=true]{section title}
\usebeamerfont{section title}Introduction\par
\end{beamercolorbox}
\endgroup
\end{frame}
\end{document}
或者你可以告诉 beamer 自动添加章节页面:
\documentclass{beamer}
\usetheme{Warsaw}
\AtBeginSection[]{
\begin{frame}
\sectionpage
\end{frame}
}
\begin{document}
\section{Introduction}
\end{document}
