无自动连字

Question 1

这microtype也有助于减少连字符，并更好地分配单词之间的空间，但请注意，shrink和stretch选项的滥用可能比连字符和过满的 \hbox 更糟糕。

\documentclass[draft]{book}
\usepackage[margin=0.5cm,paperwidth=5cm,paperheight=12
cm]{geometry}
\usepackage[english,showlanguages]{babel}
\usepackage[protrusion=true, expansion=true, shrink=55, stretch=55, 
tracking=true, kerning=true, spacing=true, 
final]{microtype}
\hyphenation{he-alth}
\newcommand\zz{%
A pandemic is an event in which a disease spreads over a very large
area, often crossing national borders. Pandemics often infect large
numbers of people, can cause many deaths, and have negative effects
on trade and the world economy. It is due to the large scale of the
negative effects of pandemics that pandemic preparedness is seen as an
important public health activity, despite the low frequency of
pandemics in comparison to other disease outbreaks. Factors implicated
in pandemic risk include travel, high population density, and changing
agricultural practices.}

Question 2

TeX 可以将文本设置为如此窄的列，但您必须进行一些调整，特别是允许更多的空白拉伸，因为即使使用连字符，在标准空白限制下也没有足够的断点。以下是三种可能性。

\documentclass{book}
\textwidth=4cm
\oddsidemargin=.1cm
\evensidemargin=.1cm
\usepackage[english,showlanguages]{babel}
\hyphenation{of-ten}
\usepackage{ragged2e}
\pdfpagewidth=8cm
\newcommand\zz{%

Question 3

由于\tolerance = 1您要求 TeX 只生成超漂亮的行 — 比它通常能生成的文本更好的行。因此它会一次又一次地失败，而且当它失败时，您不会得到很好的输出。如果您添加草稿选项，您\documentclass[draft]{book}将看到它失败了哪些行。这是我得到的：

（顺便说一下，请注意那里确实有一些连字符。）如果您只是删除您的设置\tolerance，\hyphenpenalty您将获得更好的结果，会有更多 OK 线，但仍然有几条失败的线，这些非常窄的线：

一开始不错，但后来就太难了。你确实会看到更多带有你定义的例外模式的连字符，因为它们添加了一些 TeXs 算法找不到的连字符点。例如，它只连字符大流行并且不连字符旅行。

因此，也许这种解释对您开始遇到的问题没有任何帮助，因为当尝试修复该问题时，无论是什么问题，您添加的设置都无法正常工作。
