本书采用国际上较为流行的多元大纲模式（multi-syllabus)，即吸收不同大纲模式的优点，博采众长，进行单元练习、任务和活动编排。编写团队在单元主题与输入性材料的选择上花费了很多精力，旨在语言输入材料的选择上满足以下要求：首先，单元主题需考虑到理工专业和英语学习的对接，在主题选择时不宜过分突出理工学科的专业性，材料选择方面也应以理工科普类内容为主，避免专业性较强的内容。其次，每个单元入选的2篇阅读材料紧密围绕单元主题，反映当代现实生活，内容相辅相成，以激发学习者兴趣和思辨能力。再者，输入性语言材料需要考虑到对接“一带一路”倡议对英语人才的需求，如：不仅关注发达国家的科技成就，也呈现第三世界国家的社会生活。最后，需要在材料长度和难度方面把关，文章长度介于500—750词之间，确保教材的语言知识和技能锻炼由浅入深、循序渐进，尊重语言学习规律。
教材单元架构介绍：教材中的单元由三个部分（PART）构成：
第一部分，以情景化听力任务为驱动的词汇扩展练习（Vocabulary Elicitation Driven by Listening Comprehension）。
第二部分，以知识小测验为导入方式的阅读理解任务（Reading Comprehension and Critical Thinking）。
第三部分，以第二部分文章相关段落的语言特点为范本，进行相应语法知识的输入，并服务于后续的写作练习（Grammatical Knowledge-based Writing Task）。
