最近在学习SEO（searching engine optimization）的时候受到启发，想到能用Google大数据挖掘出英语中最常见的单词。
其实方法很简单，去Google找stop word list。什么叫stop words呢？Stop word就是搜索引擎在搜索算法中忽略掉的词。为什么要忽略掉这个词呢？是因为这些词太太太常见了，以致于搜索引擎需要禁止自己的爬虫抓取这些词以节约缓存和增加搜索速度。这些常用搜索词源自大数据分析的结果。
举个例子，用百度搜索一些带”的“的词，百度就会自动省略”的“，比如你搜索”的字开头诗句“，搜搜结果会自动忽略到”的“（有点悲催）。因为“的”字太常见了。
同样道理，你用google搜索英文关键词，也会省略一些很常用的英文单词。而反过来，这些被google程序算法排出的stop word的list，自然就是我们这些学英语的人最最需要学习的单词了，而且，由于源自大数据，这可能是世界上最最精确的英语常见单词了。
当然这些单词呢，也有不足，那就是他们主要会以介词为主。不过，无论如何，这是特别好的一个单词表啦，毕竟全英语世界的人都在不自然地搜它们！！
下面是我找到的stop word list，六百个词
仅供自我学习和大家学习交流之用。
