An old man lived in the village. He was one of the most unfortunate people in the world. The whole village was tired of him; he was always gloomy, he constantly complained and was always in a bad mood. The longer he lived, the more bile he was becoming and the more poisonous were his words. People avoided him, because his misfortune became contagious. It was even unnatural and insulting to be happy next to him. He created the feeling of unhappiness in others.

任何人都可以指导我获得预期的输出。
答案1
盒子就是盒子，不是单词。如果您使用 \showbox，例如：
\documentclass{article}
\usepackage[a6paper,footskip=0pt]{geometry}
\usepackage{lastpage,everypage}
\usepackage{fwlw}
\showboxbreadth10
\showboxdepth10
\newcounter{xpage}
\AddEverypageHook{%
\showbox\LastWordBox}%
\usepackage{lipsum}
\begin{document}
\lipsum[1-3]
\end{document}
您将在日志中看到类似这样的内容：

\hbox(6.94444+1.94444)x29.72229
