我必须写一篇论文，我应该使用脚注，但有些脚注表现得很奇怪，并且没有明显的原因就留了太多空格。这是我的代码：

a lot of text\footnote{Thompson, N., \& FRED Vogelstein, F., INSIDE THE TWO YEARS THAT SHOOK FACEBOOK—AND THE WORLD, wired.com, \url{www.wired.com/story/inside-facebook-mark-zuckerberg-2-years-of-hell/} , Retrieved May 30, 2018.}

我得到以下脚注：
最后一个，以里佐尤其如此，我不知道为什么，我也尝试过启用/禁用该包url，但没有帮助。我必须使用此布局，所以我无法更改它来解决问题，有人可以看看并告诉我问题可能是什么吗？

您应该在开始文档之前使用此命令
\makeatletter
\g@addto@macro{\UrlBreaks}{\UrlOrds}
\makeatother
你发现下面的源代码

\emph{Past}
a lot of text \footnote{Barnett, W., \& Han, A, "Facebook in 2011", Case. No. E-406, May 12, 2011, pp. 1-28.}.\\
a lot of text\footnote{Thompson, N., \& FRED Vogelstein, F., INSIDE THE TWO YEARS THAT SHOOK FACEBOOK—AND THE WORLD, wired.com, \url{www.wired.com/story/inside-facebook-mark-zuckerberg-2-years-of-hell/} , Retrieved May 30, 2018.}
\bigskip
\emph{Present}
a lot of text\footnote{Rizzo, S., \& Kelly, M., Fact-checking Mark Zuckerberg's testimony on Facebook and data collection., washingtonpost.com, \url{www.washingtonpost.com/news/fact-checker/wp/2018/04/13/fact-checking-mark-zuckerbergs-testimony-on-facebook-and-data-collection}, Retrieved May 30, 2018. }
\end{document}
编译结果：
如果您想强制使用脚注的第一段文字，您可以使用如下美元表达式：
a lot of text\footnote{$\text{Rizzo, S., \& Kelly, M., Fact-checking Mark Zuckerberg's testimony on Facebook and data collection., washingtonpost.com,}$ \url{www.washingtonpost.com/news/fact-checker/wp/2018/04/13/fact-checking-mark-zuckerbergs-testimony-on-facebook-and-data-collection}, Retrieved May 30, 2018. }
结果 ：
或者像这样使用 href{}{} ：
\footnote{Rizzo, S., \& Kelly, M., Fact-checking Mark Zuckerberg's testimony on Facebook and data collection., washingtonpost.com, \href{www.washingtonpost.com/news/fact-checker/wp/2018/04/13/fact-checking-mark-zuckerbergs-testimony-on-facebook-and-data-collection}{www.washingtonpost.com/..../fact-checking-mark-zuckerbergs-testimony-on-facebook-and-data-collection}, Retrieved May 30, 2018.}
