如果你有一本书，它是用你所不懂的一种语言写的，你要做的第一件事是看看字母的顺序。在你能弄懂这种语言并且搞清它说的是什么意思之前，你还有许许多多的事情要做。

• If you have a book that is written in a language you don't understand,the first thing would be to look at the sequence of letters but there still would be a lot more work to be done before you could understand the language and what it is about.
