请给我LaTeX一些建议，说明如何将单词Chapter 1显示在目录中，而不是仅1在下一章中显示等等。以下是我们大学论文的模板：

我建议您使用该tocloft包来实现您的格式化目标。请注意仅有的下面的代码所做的就是在章节号前插入单词“Chapter”（和空格）。特别是，section目录中的 -level 条目的外观没有被修改。
\documentclass{book}
\usepackage{calc} % for '\widthof' macro
\usepackage[titles]{tocloft}
\renewcommand\cftchappresnum{Chapter }
\cftsetindents{chap}{0pt}{\widthof{\large\textbf{Chapter 1}}}
\begin{document}
\tableofcontents
\chapter{AAA}
\section{A1}
\section{A2}
\chapter{BBB}
\section{B1}
\section{B2}
\end{document}
