不能，高亮显示功能是高亮显示关键字、各种括号，自己定义的变量不是关键字，所以不能高亮显示，不光是在Vim，其他的文本编辑器也是一样的。

用vim很多年了。没明白你所说的高亮红和高亮绿是个什么情况。
常年用vim的人一般都会有为自己定制的vim。所以你说这种高亮、红、绿，估计很多人不会明白是什么意思。我的c语言里面就完全没有类似的。对应的Python配置里面倒是有块状红色，表示那一行代码逻辑或者语法上有明显错误。
在~/.vimrc中加入syntax on就行了。下面是我的配置文件，可以直接用，我也是在网上拼凑的
" All system-wide defaults are set in $VIMRUNTIME/debian.vim (usually just
" /usr/share/vim/vimcurrent/debian.vim) and sourced by the call to :runtime
" you can find below. If you wish to change any of those settings, you should
" do it in this file (/etc/vim/vimrc), since debian.vim will be overwritten
" everytime an upgrade of the vim packages is performed. It is recommended to
" make changes after sourcing debian.vim since it alters the value of the
" 'compatible' option.
" This line should not be removed as it ensures that various options are
" properly set to work with the Vim-related packages available in Debian.

" Uncomment the next line to make Vim more Vi-compatible
" NOTE: debian.vim sets 'nocompatible'. Setting 'compatible' changes numerous
" options, so any other options should be set AFTER setting 'compatible'.
