TeX 会尝试避免段落结尾之前的行有连字符。您可以通过更改以下内容来允许这样做\finalhyphendemerits
:
\documentclass{article}
\begin{document}
hippopotamus, hippopotamus, hippopotamus, hippopotamus, hippopotamus \dotfill
23 24 25
\finalhyphendemerits =0 hippopotamus, hippopotamus, hippopotamus,
hippopotamus, hippopotamus \dotfill 23 24 25
\end{document}
