放弃所有手动进行的页面相关设置，只使用geometry，甚至在\documentclass水平上。也就是说，摆脱手动设置

\textwidth
\textheight
\hoffset
\voffset
\oddsidemargin
\evensidemargin
\topmargin

乃至

\special{papersize=8.4375in,11in}

只需使用

\usepackage{geometry}
\geometry{
  paper = letterpaper,
  left = 1.5in,
  right = 1in,
  vmargin = 1in% (similar to top=1in and bottom=1in)
}
