When you look out your front door, you can probably see your next-door neighbor, the end of the street, or perhaps a store or park in your neighborhood. But what would you see if you were in a spaceship? Watching Earth From Space will tell you exactly what you might see-and show you with amazing photographs! This book will also inform you about what scientists learn by being able to see our planet from space and how that information helps all of us.

当您从前门向外看时，您可能会看到隔壁邻居、街道尽头，或者您附近的商店或公园。 但是，如果您在宇宙飞船中，您会看到什么? 从太空观看地球将告诉您您可能会看到的确切内容，并向您展示令人惊叹的照片! 这本书还将告诉您科学家通过从太空看到我们的星球而学到的东西，以及这些信息如何帮助我们所有人。

RAZ本身有着非常严密的分级体系：根据全文词汇数、高频词词汇数与比例、低频词词汇数与比例、句子长度、句子复杂度、句式、插图信息量、思想深度、主题等多个角度，将整个阅读体系分为aa，A-Z共27个级别。

AA—C这4个级别对应幼儿园阶段; D—J这7个级别对应美国小学一年级;K—P这6个级别对应美国小学二年级;Q—T这4个级别对应美国小学三年级;U—W这3个级别对应美国小学四年级;X—Z对应美国小学五六年级(相当于国内高中毕业)。

N级已经达到初中毕业的水平，词汇量超过600个，语法上涉及国内初中重要的所有语法(各种时态，灵活的副词和形容词，形象的动词词组，定语从句，宾语从句，状语从句等)。
