写在最前

在国内各类电子词典软件越来越毒瘤的趋势下，广告漫天飞舞，甚有会员+课程的捆绑式销售正在向你张开着血盆大口。我也很早就想和他们Say Goodbye了。

牛津出版社的Oxford Advanced Learner's Dictioneries（OALD）可谓是在词典当中最为权威的之一，在其网页版本词典中也提供了完备的查阅功能，还拓展性地展示了分类的单词表和语法内容介绍。

让我认为值得选择牛津OALD词典的一点是，不同于多数双语词典直接给你反馈中文结果，牛津词典的结果是全英文采用了简单的词汇来对这一个单词展开描述，以便让你理解。纵使直观的给出中文往往会让你快速理解，但却殊不知在记忆上形成一定的障碍。中文到英文的环境切换是跨度是远比英文到其他日耳曼语系语言的跨度大的。所以全英文的模式可以在一定程度上可以帮助你从英文语境上理解记忆单词的含义。

在Google Play上不难看到，官方早已上架了OALD的官方APP，然而当你安装后才会发现，它没有直接在play商店内让你付费购买，却是将会员资格和你的Oxford账户绑定，除非购买订阅每月$1.99或者每年$10.99美金的订阅会员，否则你在这款应用将无法查询单词。

于是我就采用FA重构了OALD网页版并封包为了安卓应用。从这里你可以简洁的浏览一切源自OALD词典上的内容，包括快速查询、每日一词、语法浏览、单词列表等，而无需观看广告内容并为此付费。

If you want to land a job in Amazon and you have heard that learning these leadership principles is extremely important to your interview's success, this is the right series of articles to follow.

Or, maybe you just are interested in how Amazon does things and want to learn from this global giant, in which case, this is also the right series of articles to follow.

Or you are just curious or bored — I guarantee you, you will find this series interesting.
Let’s start with some personal rant as a preface to this series, which is —
