为什么 natbib 包找不到作者?

为什么 natbib 包找不到作者?

我有一个如下的 .bib 文件:

%% This BibTeX bibliography file was created using BibDesk.
%% http://bibdesk.sourceforge.net/
%% Saved with string encoding Unicode (UTF-8) 

@book{marcu2000theory,
    Author = {Marcu, Daniel},
    Date-Added = {2013-02-12 04:56:47 +0000},
    Date-Modified = {2013-02-12 04:56:47 +0000},
    Publisher = {MIT Press},
    Title = {The theory and practice of discourse parsing and summarization},
    Year = {2000}}

我的乳胶文件:

\documentclass{article} % For LaTeX2e
\usepackage{graphicx}
\usepackage{url}
\usepackage{natbib}

\title{T}

\begin{document}
\maketitle
\cite{marcu2000theory}
\citeauthor{marcu2000theory}

\bibliography{DPSurvey}
\bibliographystyle{plain}

\end{document}

然而,我总是收到警告:

Author undefined for citation`marcu2000theory' (natbib) on page 1

有人能指出错误吗?

使用natbib替换plain style, plainnat.bst。若要获得数字引用,请使用numbers选项。

\usepackage[numbers]{natbib}
\bibliographystyle{plainnat}
