hello this is a quote

> fonts
---\bf Bold fonts
---\it Italy fonts
---\rm Roman fonts
---\sl Slanted fonts
> {} mean a group like in C/C++.
> % ignores everything following it untill end of line.
> Something should be noted:
---A <return> is like a space.
---Two spaces in a row seem as one space.
---A blank line denotes the end of a paragraph
> In mathematics, '\$'->$, '\}'->}, '\%'->%, '\&'->&, '\#'->#.
> '\char<number>' stand for the symbel ( 0~255 )
> Must know '\S' '\dag' '\ddag'
> Unit of measure:
---pt point (baselines are 12pt)
---pc pica (1pc = 12pt)
---in inch (1in = 72.27pt)
---bp big point (72bp = 1in)
---cm centimeter (2.54cm = 1in)
---mm millimeter
---dd didot point
---cc cicero
---sp scaled point
> Should use \/ when shifting from a slanted font to unslanted one.
> symbel '~' or '\ ' donates a normal space.
> '\indent' does a indentation in horizontal mode.(\noindent)
> '$$(a+b)$$' would interrupts an paragraph.
> '\par' denotes an end of a paragraph.
> '~' seems as a space except don't broken by TeX.
> In mathematic mode, TeX will ignore any spaces between $'s.
> $$\alpha,\beta,\gamma,\delta;$$
> Note the difference: ${x^y}^z$, $x^{y^z}$
> Some important mathematic characters:

$\sqrt{a+b}$
$\overline{a+b}$
$\x^{a+b}$
$\root n \of x$
$\bar a$
$\vec a$

 > $q_i^e$ == $q^e_i$
> Backslash: $\backslash$ or \textbackslash
> Note the difference: $(f+g)'$ and ${(f+g)}'$
> Some More Infomation about Math

$$a+b\over c+d$$
$$k\choose n$$
$$a+b\atop d+c$$
$$\sum x_n$$

 > The Size of Pairs: \bigl,\Bigl,\biggr,\Biggr
> If you want use Roman type in formulas: {\rm roman}
> Use \quad \qquad  in the formula of blank.
> \ldots,\cdots,\vdots,\ddots
> Macros: \def\REP{for}

> insert a figure:

\usepackage{graphicx}
\usepackage{subfigure}
\begin{document}
\begin{figure}
\centering
\subfigure[foo]{
　　\label{Fig.sub.1}
　　\includegraphics[width=0.4\textwidth]{1.jpg}
}
\subfigure[bar]{
　　\label{Fig.sub.2}
　　\includegraphics[width=0.4\textwidth]{2.jpg}
}
\end{figure}
\end{document}

> use columns in beamer

\begin{columns}
\begin{column}{0.4\paperwidth}{
	\begin{itemize}
	\item foo
	\item bar
	\end{itemize}
}\end{column}
\begin{column}{0.4\paperwidth}{
	\begin{example}
	\item hello
	\item world
	\end{example}
}\end{column}
\end{columns}

 > multiple authors list in beamer

\documentclass{beamer}
\begin{document}
\title{aaaa}
\author{\begin{tabular}{lll}
　　A & B & C\\
　　123 & 234 &456
\end{tabular}}
\maketitle
\end{document}
