将一段文本与两列页面的左下角对齐

Question

我正在尝试将一段文本对齐到双列文档的左下角。这段文本应填满左列的宽度，并应向上流动以获得所需的空间。当到达这段文本时，双列格式应从第一列溢出到下一列。我使用“带框”和“阴影”将文本放入单独的框中，但这似乎只是与正常文本一起流动。

这样做的目的是在大学提交的论文正面加入一份声明。位置很重要。

\documentclass[a4paper,10pt,english]{article}   

\usepackage{framed}
\usepackage{xcolor}
\usepackage{lipsum}

\definecolor{shadecolor}{rgb}{0.95,0.95,0.95}
\definecolor{frameborder}{rgb}{0,0,0}

\begin{document}
    \twocolumn
    \section{Introduction}
        \lipsum[3-5]

        \begin{shaded*}

It is also declared that this report has not previously been submitted, in whole or in part, as part fulfilment of any module assessment requirement.\\ \\

        \end{shaded*}

        \lipsum[6]

\end{document}

Answer 1

我不确定这是否足够，但我使用了浮点环境（在本例中figure为 ，尽管float可以创建一个新类型）和[b]说明符将其放置在第一列的底部。但是，我发现环境shaded干扰了这种方法，所以我用 代替shaded了\colorbox{\parbox{}{}}。
