1.New Scientist 这本杂志被用到的频率最高，如剑四中的Lost for Words, Play is a Serious Business，剑五中的What’s So Funny?, Flawed Beauty: the Problem with Toughened Glass，和剑六中的多篇文章 Australia’s Sporting Success, Climate Change and the Inuit, Graying Population Stays in the Pink, Do Literate Women Make Better Mothers?

2.The Economist 列居其次，如剑五中的The Truth about the Environment, 剑六中的Delivering the Goods

3.还有American Scientist和Scientific American这两个主要的美国学术期刊，例如剑五的Disappearing Delta和剑六的The Search for Anti-aging Pills

4.当然还有National Geographic。但是值得注意的是，因为这是休闲杂志，所以只作为了G类的阅读，如剑六中的Pterosaurs
