itemize我需要在 中的项目之间添加引号beamer frame。如果我itemize在引号附近停止并重新开始，结果根本不会缩进：
\documentclass{beamer}
\usetheme{CambridgeUS}
\usefonttheme{serif}
\setbeamerfont{quote}{shape=\upshape,family=\rmfamily}
\beamerdefaultoverlayspecification{<+->}
\begin{document}
\begin{frame}{Frame}
\begin{itemize}
\item Lorem ipsum dolor sit amet, consectetur adipiscing elit.
\end{itemize}
\begin{quote}Sed vitae purus facilisis, blandit odio eget, tincidunt nisi. Aliquam pulvinar, ipsum ac aliquet facilisis, neque quam tincidunt lacus, at eleifend ante lorem quis neque. Suspendisse potenti. \end{quote}
\begin{itemize}
\item Nulla vel bibendum ligula. Sed imperdiet felis lacus, a vulputate urna egestas at.
\end{itemize}
\end{frame}
\end{document}
但如果我不重新启动，引文就会缩进太多：
\documentclass{beamer}
\usetheme{CambridgeUS} \usefonttheme{serif} \setbeamerfont{quote}{shape=\upshape,family=\rmfamily}
\beamerdefaultoverlayspecification{<+->}
\begin{document}
\begin{frame}{Frame}
\begin{itemize}
\item Lorem ipsum dolor sit amet, consectetur adipiscing elit. \smallskip{}
\begin{quote}Sed vitae purus facilisis, blandit odio eget, tincidunt nisi. Aliquam pulvinar, ipsum ac aliquet facilisis, neque quam tincidunt lacus, at eleifend ante lorem quis neque. Suspendisse potenti. \end{quote}
\item Nulla vel bibendum ligula. Sed imperdiet felis lacus, a vulputate urna egestas at.
\end{itemize}
\end{frame}
\end{document}
我猜我必须quote从 重新定义环境beamerbaselocalstructure.sty。那该怎么办？它可能在beamer用户指南中，但我找不到它。

使用changepage环境adjustwidth来调整引文周围的边距：
\documentclass{beamer}
\let\Tiny\tiny% http://tex.stackexchange.com/a/94159/5764
\usepackage{changepage}
\usetheme{CambridgeUS}
\usefonttheme{serif}
\setbeamerfont{quote}{shape=\upshape,family=\rmfamily}
\beamerdefaultoverlayspecification{<+->}
\begin{document}
\begin{frame}{Frame}
\begin{itemize}
\item Lorem ipsum dolor sit amet, consectetur adipiscing elit. \smallskip{}
\begin{quote}
Sed vitae purus facilisis, blandit odio eget, tincidunt nisi. Aliquam pulvinar, ipsum ac aliquet facilisis, neque quam tincidunt lacus, at eleifend ante lorem quis neque. Suspendisse potenti.
\end{quote}
\begin{adjustwidth}{1em}{1em}
Sed vitae purus facilisis, blandit odio eget, tincidunt nisi. Aliquam pulvinar, ipsum ac aliquet facilisis, neque quam tincidunt lacus, at eleifend ante lorem quis neque. Suspendisse potenti.
\end{adjustwidth}
\item Nulla vel bibendum ligula. Sed imperdiet felis lacus, a vulputate urna egestas at.
\end{itemize}
\end{frame}
\end{document}
您可以使用（例如）对quote环境进行完全替换adjustwidth
\renewenvironment{quote}[1][1em]
{\begin{adjustwidth}{#1}{#1}}
{\end{adjustwidth}}
上述重新定义提供了
\begin{quote}[<margin>]
<quote>
\end{quote}
带有一个可选<margin>参数，用于调整左边距和右边距。
