当然，有些事实证据是有效的，比如玛雅人的确有一个长记历的历法，地磁反转理论也的确存在，太阳活动的确在减弱等等。
Certainly, some of the facts at hand are valid; for example, the Maya did have a Long Count calendar, pole-shift theory does exist, and solar activity does wax and wane.
实际上，我用得还相当上手，我会做一些关键的系统改进，比如电脑启动时自动加载本地磁盘，创建页面文件，改变GRUB的启动菜单等。
In fact, I was working flawlessly at the terminal, did critical system modifications such as auto-mounting local hard drives on start-up, creating a Pagefile, and changing the GRUB boot menu.
如果只需要查询本地磁盘上的XML文档(也是本文的重点)，连接的设置非常简单。
When you're just querying XML documents on a local disk (which is what this article focuses on), setting up a connection is pretty straightforward.
