Latex : Extra page remove

Question

I am new to LaTeX. I have no idea about it at all and I am facing a problem. When writing a report the NEW CHAPTER always starts with odd page causing an empty page on my report. How can I remove it? I have read other answers on stackoverflow but could not make out what to be done.

\documentclass[12pt]{report} 
\usepackage[top=1in, bottom=1in, left=1in, right=1in]{geometry}
\usepackage{graphicx} 
\usepackage{times} 
\begin{document} 
%\pagestyle{empty} 
\input{first} 
\pagestyle{plain} 
\pagenumbering{arabic} 
\newpage 
\input{declaration} 
\newpage 
\input{acknowledgement} 
\newpage 
\input{abstract} 
\tableofcontents 
\listoffigures 
\input{chapter1} 
\include{chapter2} 
\include{chapter3} 
\include{conclusion} 
\include{references} 
\pagestyle{plain} 
\pagenumbering{arabic} 
\addcontentsline{toc}{chapter}{References} 
\end{document}

first.tex

\begin{titlepage}
\begin{center}
   Some title text
\end{center}
\end{titlepage}

Answer 1

So I solved my problem. What i did was i remove \begin{flushleft} from all the chapters and used RaggedRight at the main tex file.
