我无法将章节/小节与其对应的章节/小节对齐。请参见以下示例：
以下是迄今为止输入的所有代码：
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{amssymb}
\usepackage{comment}
\begin{document}
\section{Operational rules for constructing an upper line with a basic step motion}
\subsection{The basic step motion}
\begin{enumerate}
\item The final pitch in the basic step motion must be a tonic.
\item The first pitch in the basic step motion must be a tonic triad member a third, a fifth, or an octave above the final pitch.
\item These two pitches must be joined by inserting the pitches of intervening diatonic degrees to form a descending step motion.
\subsection{Beginning of Two-Voice Setting}
\end{enumerate}
\end{document}
我已经看到一些与边距和以英寸为单位移动文本相关的问题，但我很好奇是否存在我可能遗漏的更简单的方法。
谢谢。

在枚举环境中有第二个子节 (1.2)。更改如下：
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{amssymb}
\usepackage{comment}
\begin{document}
\section{Operational rules for constructing an upper line with a basic step motion}
\subsection{The basic step motion}
\begin{enumerate}
\item The final pitch in the basic step motion must be a tonic.
\item The first pitch in the basic step motion must be a tonic triad member a third, a fifth, or an octave above the final pitch.
\item These two pitches must be joined by inserting the pitches of intervening diatonic degrees to form a descending step motion.
\end{enumerate}
\subsection{Beginning of Two-Voice Setting}
\end{document}
答案2
前提：我怀疑这个解决方案虽然看起来可行，但有点复杂。也许一些大师可以找到一个优雅的解决方案。
我不明白为什么要把 放在\subsection里面enumerate，正如@Fran- 指出的那样。但是\subsection向右移动了\leftmargin。然后我们必须将 的缩进\subsection从修改\z@为-\leftmargin，但前提是命令是在列表中给出的。这可以通过 轻松完成etoolbox：
\pretocmd{\list}{\patchcmd{\subsection}{\z@}{-\leftmargin}{}{}}{}{}
平均能量损失
\documentclass{article}
\usepackage{etoolbox}
\makeatletter
\pretocmd{\list}{\patchcmd{\subsection}{\z@}{-\leftmargin}{}{}}{}{}
\pretocmd{\list}{\patchcmd{\subsubsection}{\z@}{-\leftmargin}{}{}}{}{}
\makeatother
