# Change abstract page position to top in report format

My document type should be report and I need to start my abstract at the top of the page. But with the below code, the abstract is centered on the page. What do I need to do? (I cannot change the type of document.)

\documentclass[12pt,a4paper,oneside]{report}
\begin{document}
\begin{abstract}
.................
\end{abstract}
\end{document}

With the titlepage class option (which is the default in report), the start of the abstract environment contains \null\vfil which (together with a corresponding \vfil\null at the end) vertically centers the environment. Remove \null\vfil, e.g. with the help of the etoolbox package.

\documentclass{report}

\usepackage{etoolbox}
\patchcmd{\abstract}{\null\vfil}{}{}{}

\usepackage{lipsum}

\begin{document}

\begin{abstract}
\lipsum[1]
\end{abstract}

\end{document}
