我想在我的文章中引用一些参考文献。（我用了\cite{}。）然而，结果却出现了一些粗体字而不是引用编号。这是我的代码：
\usepackage{url}
\renewcommand{\UrlFont}{\small\tt}
\usepackage{graphicx}
\usepackage{epstopdf}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{tikz}
\usepackage{filecontents}
\usepackage[style=verbose]{biblatex}
\usepackage{graphicx}
\graphicspath{ {images/} }
\usetikzlibrary{automata,arrows,positioning,calc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{setspace}
\section{Data}
The data were collected from ITTF \cite{ITTF}.
\begin{thebibliography}{1}
\bibitem{J}
McGarry, T., and Franks, I.M.,
A stochastic approach to predicting competition squash match-play,
\emph{Journal of Sport Sciences}, 1994, 12, 573-584.
\bibitem{l}
Lames, M.
\emph{Leistungsdiagnostik durch Computersimulation. [Performance diagnosis by computer simulation]}.

由于您似乎完全是手动构建参考书目，因此加载biblatex包是没有意义的。相反，您应该加载一个引文管理包，例如cite，它可以生成数字引文调出。（如果您不想加载包cite，您可以natbib使用选项加载包numbers；但是，您还必须提供一个虚拟\bibliographystyle指令。）如果加载了这样的引文管理包，您将能够使用单个命令生成多个引文调出（如果适用，则进行排序和压缩）\cite。
