美高环境科学衔接手册

《美高环境科学衔接手册》是一本写给中国学生的环境科学入门书。它要解决的问题很具体：中国的高中课程表里根本没有'环境科学'这门课。相关的碎片当然存在--地理课讲过大气环流和水循环，生物课讲过生态系统和食物链，化学课讲过酸雨的成因--但这些碎片分散在四五门不同的课里，彼此之间没有被串起来，也从来没有被当成一门有自己方法论的学科来教。所以，当一个中国学生第一次坐进美高的 Environmental Science 课堂时，他面对的不是'学过但不会用英文说'，而是'压根没系统学过'。这本书就是为这一步准备的。全书按九个单元展开：生态系统、生物多样性、种群与人口、地球系统与资源、土地与水资源利用、能源资源与消费、大气污染、水与陆地污染、全球变化。每一章都从零讲起--先给定义，再讲机制，最后落到计算与英文表达。书里有三样东西是特意为'衔接'设计的：一是双语术语桥，每个重点术语都给出'用英文表达为......'，让学生在课堂上听得懂、说得出；二是美国语境导览，把 Clean Air Act、Clean Water Act、Superfund、Dust Bowl、Montreal Protocol 这些美国课堂默认你知道、而中国学生完全陌生的背景，用独立的板块讲清楚；三是把每一道计算题的思路、步骤、单位和自检过程全部写出来，不跳步。A Bridge to U.S. High School Environmental Science is an introduction to environmental science written specifically for Chinese students entering American high schools. It addresses a concrete problem: Chinese high schools do not teach environmental science as a subject at all. Fragments of it exist - atmospheric circulation and the water cycle appear in geography, ecosystems and food chains in biology, the chemistry of acid rain in chemistry - but those fragments sit in four or five separate courses, are never connected, and are never taught as a discipline with its own way of thinking. So when a Chinese student walks into an American Environmental Science classroom for the first time, the difficulty is not 'I know this but can’t say it in English.' It is that the subject was never systematically learned in the first place. This book is built for that gap.The book covers nine units: ecosystems, biodiversity, populations, Earth systems and resources, land and water use, energy resources and consumption, atmospheric pollution, aquatic and terrestrial pollution, and global change. Every chapter assumes zero background - it defines before it explains, explains the mechanism before it applies it, and ends in calculations and English expression.Three features are designed specifically for the transition. A bilingual terminology bridge gives the English phrasing for every key term, so students can follow the lecture and speak up in it. Standalone U.S.-context sections explain the background an American classroom simply assumes you know - the Clean Air Act, the Clean Water Act, Superfund, the Dust Bowl, the Montreal Protocol. And every calculation is worked out in full: the reasoning, each step, the units, and a self-check.
