我计划清理一个大型 TeX 文件，以便在电子阅读器上查看（因此页面尺寸较小），因为我对 TeX 还不熟悉，所以我在示例文件和以下这些说明。但是，我无法使用常见修复。给定以下 TeX（完整文档在末尾）：
\begin{enumerate}
\item {\small First Subpoint (Small Font)}
\item {\tiny Second Subpoint (Tiny Font)}
\item {\Huge Third Subpoint (Huge Font)}
\end{enumerate}
我尝试调整 \pretolerance，但没有效果，而 \sloppypar 也很马虎：
可能最好的外观就是“第三子点”的“常规”间距，左对齐，下一行有“（大字体）”。但我不确定使用什么间距或对齐设置来解决问题（或者为什么行宽“无效”而不凌乱）。任何建议都将不胜感激。谢谢！

\title{Sample \LaTeX ~File}
\author{David P. Little}
\maketitle
\begin{abstract}
This document represents the output from the file ``sample.tex" once compiled using your favorite \LaTeX compiler. This file should serve as a good example of the basic structure of a ``.tex" file as well as many of the most basic commands needed for typesetting documents involving mathematical symbols and expressions. For more of a description on how each command works, please consult the links found on our course webpage.

\subsection{Binomial Theorem}
\begin{theorem}[Binomial Theorem]
For any nonnegative integer $n$, we have
$$(1+x)^n = \sum_{i=0}^n {\binom{n}{i}} x^i$$
\end{theorem}
\subsection{Taylor Series}
The Taylor series expansion for the function $e^x$ is given by
\begin{equation}
e^x = 1 + x + \frac{x^2}{2} + \frac{x^3}{6} + \cdots = \sum_{n\geq 0} \frac{x^n}{n!}
\end{equation}
\subsection{Sets}
\begin{theorem}
For any sets $A$, $B$ and $C$, we have
$$ (A\cup B)-(C-A) = A \cup (B-C)$$
\end{theorem}
\begin{proof}
\begin{eqnarray*}
(A\cup B)-(C-A) &=& (A\cup B) \cap (C-A)^c\\
&=& (A\cup B) \cap (C \cap A^c)^c \\
&=& (A\cup B) \cap (C^c \cup A) \\
&=& A \cup (B\cap C^c) \\
&=& A \cup (B-C)
\end{eqnarray*}
\end{proof}
