用简单的英语，“git reset”有什么作用？

问题：

I have seen interesting posts explaining subtleties about git reset . 我看到有趣的帖子解释了关于git reset微妙之处。

Unfortunately, the more I read about it, the more it appears that I don't understand it fully. 不幸的是，我读的越多，我就越不能完全理解它。 I come from a SVN background and Git is a whole new paradigm. 我来自SVN背景，Git是一个全新的范例。 I got mercurial easily, but Git is much more technical. 我很容易变得善变，但Git更具技术性。

I think git reset is close to hg revert , but it seems there are differences. 我认为git reset接近hg revert ，但似乎存在差异。

the strange notation you use with HEAD such as HEAD^ and HEAD~1 ; 与HEAD使用的奇怪符号，如HEAD^和HEAD~1 ;
