目前我必须做这样的事情：
此外，当重新引入问题时，学生的\linebreak知识保留率也增加了近12％。
否则，知识将在 pdf 中分离，例如：知识。
请问有什么帮助吗？
答案1
示例文件：
\documentclass[twocolumn]{article}
\begin{document}
Some words words words.
In addition, the knowledge retention rate of the students also
increased by almost 12\% when questions were reintroduced.
\end{document}
该twocolumn选项旨在显示换行符，而不会产生太长的句子。
根据韦伯斯特词典，knowl-edge是美式英语中正确的连字符。
英式英语的连字符似乎有所不同（很常见）：
\documentclass[twocolumn]{article}
\usepackage[british]{babel}
\begin{document}
Some words words words.
In addition, the knowledge retention rate of the students also
increased by almost 12\% when questions were reintroduced.
\end{document}
现在，您需要决定使用美式英语还是英式英语连字规则和拼写。如果您想覆盖连字规则并仍然使用美式英语，请添加
\hyphenation{know-ledge}
到您的文档序言中。
\documentclass[twocolumn]{article}
\hyphenation{know-ledge}
\begin{document}
Some words words words.
In addition, the knowledge retention rate of the students also
increased by almost 12\% when questions were reintroduced.
\end{document}
输出将与上面第二张图片相同。
