如何建议段落后多栏分隔符

Question

您如何建议段落后的多列分隔符？我想要一些类似多列环境的参数，而不需要手动的\columnbreak。

\documentclass{article}

\usepackage{multicol}

\begin{document}
\begin{multicols}{2}
  This is a first paragraph 
  This is a first paragraph 
  This is a first paragraph

  \textbf{This is a second paragraph
  This is a second paragraph
  This is a second paragraph
  This is a second paragraph
  This is a second paragraph
  This is a second paragraph}

  This is a third paragraph
  This is a third paragraph
\end{multicols}
\end{document}
