由于某种原因，我的“语言”章节没有正确显示：就好像它的某些部分不符合我的页面布局（参见屏幕截图中的 A）。
此外，这可能与此相关，现在“第 1 章”后面紧接着出现了一个空白页，而“第 2 章”应该出现在那里（参见屏幕截图中的 B）。
任何帮助都将不胜感激。谢谢。

答案1
好的，我会尝试一下：
所有分段命令都不允许在其后立即出现分页符，以防止它们单独存在。一旦将文本添加到相应的部分，将自动出现分页符后文本。
因此，添加任意文本，或 \mbox{} 作为大卫建议可以解决你的问题。
对于背景我自己做了一些研究，并将尽力根据命令进行解释\section：
命令\sectionbook班级定义为
\newcommand\section{\@startsection {section}{1}{\z@}%
{-3.5ex \@plus -1ex \@minus -.2ex}%
{2.3ex \@plus.2ex}%
{\normalfont\Large\bfseries}}
其中的\@startsection命令实际上是一个低级的 TeX 命令：
\def\@startsection#1#2#3#4#5#6{%
\if@noskipsec \leavevmode \fi
\par
\@tempskipa #4\relax
\@afterindenttrue
\ifdim \@tempskipa <\z@
\@tempskipa -\@tempskipa \@afterindentfalse
\fi
\if@nobreak
\everypar{}%
\else
\addpenalty\@secpenalty\addvspace\@tempskipa
\fi
\@ifstar
{\@ssect{#3}{#4}{#5}{#6}}%
{\@dblarg{\@sect{#1}{#2}{#3}{#4}{#5}{#6}}}}
这里我们有一个\if@nobreak \everypar{}，它延迟\nobreak命令直到文本添加完毕，以防止该文本与分段命令分离（来源)。一旦 (La)TeX 遇到文本，就会\nobreak插入。
现在，我认为，原文\nobreak是由\@xsect命令插入的，定义在latex.ltx
\def\@xsect#1{%
\@tempskipa #1\relax
\ifdim \@tempskipa>\z@
\par \nobreak
\vskip \@tempskipa
\@afterheading
\else
\@nobreakfalse
\global\@noskipsectrue
\everypar{%
\if@noskipsec
\global\@noskipsecfalse
{\setbox\z@\lastbox}%
\clubpenalty\@M
\begingroup \@svsechd \endgroup
\unskip
\@tempskipa #1\relax
\hskip -\@tempskipa
\else
\clubpenalty \@clubpenalty
\everypar{}%
\fi}%
\fi
\ignorespaces}
它又被\@sectever 中使用的宏调用@startsection
\def\@sect#1#2#3#4#5#6[#7]#8{%
\ifnum #2>\c@secnumdepth
\let\@svsec\@empty
\else
\refstepcounter{#1}%
\protected@edef\@svsec{\@seccntformat{#1}\relax}%
\fi
\@tempskipa #5\relax
\ifdim \@tempskipa>\z@
\begingroup
#6{%
\@hangfrom{\hskip #3\relax\@svsec}%
\interlinepenalty \@M #8\@@par}%
\endgroup
\csname #1mark\endcsname{#7}%
\addcontentsline{toc}{#1}{%
\ifnum #2>\c@secnumdepth \else
\protect\numberline{\csname the#1\endcsname}%
\fi
#7}%
\else
\def\@svsechd{%
#6{\hskip #3\relax
\@svsec #8}%
\csname #1mark\endcsname{#7}%
\addcontentsline{toc}{#1}{%
