为什么 \parbox 会使单词间距变得很宽以及如何修复它？

Question

如何保留\parbox并同时消除单词之间过多的间距？

\documentclass[varwidth]{standalone}
\begin{document}
    \parbox{40mm}
      { \everypar{\parshape 2 0mm 40mm 5mm 35mm}
        This is sentence 1. This is sentence 2.
        This is sentence 3. This is sentence 4.
        This is sentence 5. This is sentence 6.
        \par
      }
\end{document}

Answer 1

因为你的右对齐框很小。句子的性质，你的长单词sentence不能很好地换行，而且没有其他地方可以换行，这意味着结果只能是其他方式。你还能在哪里换行？你不能在其他地方换行，所以为了实现对齐，你只能这样做。如果你有对齐和窄列或页面或其他东西，这种情况总是会发生。有什么替代方案？不是\parbox，如果你将边距设置得非常宽以给文本提供相同的空间，也会发生同样的情况

您想删除默认的右对齐吗？

\documentclass[varwidth]{standalone}
\begin{document}
    \parbox{40mm}
      { \everypar{\parshape 2 0mm 40mm 5mm 35mm}\raggedright
        This is sentence 1. This is sentence 2.
        This is sentence 3. This is sentence 4.
        This is sentence 5. This is sentence 6.
        \par
      }
\end{document}

Answer 2

\parbox 在其初始化代码中调用 \sloppy。您可以将其重置为 \fussy，但这很容易导致行过满。（我删除了句号，因为句号后面的空间较大，很难看出区别）：

\documentclass{article}

\begin{document}
    \parbox{40mm}
      {\everypar{\parshape 2 0mm 40mm 5mm 35mm}
        This is sentence This is sentence 
        This is sentence  This is sentence 
        This is sentence This is sentence 
      }

\bigskip        
    \parbox{40mm}
      {\everypar{\parshape 2 0mm 40mm 5mm 35mm}
        \fussy
This is sentence  This is sentence 
        This is sentence  This is sentence 
        This is sentence  This is sentence 
      }
\end{document}
