Beamer 首页

Question

我正在尝试使用在互联网上找到的模板在 Beamer 中创建首页幻灯片。我不知道在模板或 TeX 文件中要更改什么才能获得我想要的效果；我的目标是获得图像中的高光部分

我的 TeX 文件如下：

\documentclass[english]{beamer}

\mode<article> % only for the article version
{
  \usepackage{fullpage}
  \usepackage{hyperref}
}


\mode<presentation>
{
  %\setbeamertemplate{background canvas}[vertical shading][bottom=red!10,top=blue!10]
  \setbeamercovered{transparent}
  \usetheme{progressbar}
  \usefonttheme{serif}
  \usecolortheme{crane}
}

\usepackage{pgf,pgfarrows,pgfnodes,pgfautomata,pgfheaps,pgfshade}
\usepackage[latin1]{inputenc}
\usepackage{colortbl}

\setbeamercovered{dynamic}

\setbeamertemplate{items}[circle]

\title[]{{\LARGE {\sc Title 1}} \vspace*{0.5cm}}

\author{{\bf Title 2} \\ {\it Title 3}}

\date{Author}

\begin{document}

\begin{frame}

\maketitle

\end{frame}

\begin{frame}
\vfill \centering Title 4 \vfill
\end{frame}

\begin{frame}
This is my first slide...
\end{frame}

\end{document}

编译需要5个样式文件，我无法上传这些文件，因此我将在下面贴出相应的代码。
