1．8 Checkpoint 2是本单元语言知识的反馈和强化。分为谓语形式和单元话题词汇与句式复习两个部分，此项内容可以作为反馈练习来强化单元知识。
1．5 LANGUAGE STUDY 分词汇和语法两部分。其中，Word study的前两个练习序列性很强，两个练习设计注重词性拓展和运用。任务中基本涉及到本单元重点词汇和常见词汇，但是对学生而言，仅依靠这样两个任务设计是不能够达到熟练的目的，因此应该适当的在Homework或者Integrating Skills部分运用恰当的任务设计来达到使学生能够熟练运用这些词汇的目标。Word Study的第三个练习训练学生在语境中运用词汇的能力，材料内容补充了本单元话题的背景知识。Word Study基本上呈现出了本单元的重点词汇，任务形式以训练为载体，强调了语言知识的运用能力，因此教学中要细处理。Grammar 则分成两个Parts. Part 1要求学生要学会识别和判断Predicate；Part2强调了Predicate在语篇中的运用。由于是复习内容，所以两个Task的内容设计显得简单，可以适当补充一些Tasks来强化学生在写作过程中准确运用Predicate的能力。
1．4 READING部分包括Pre-reading, Reading 和Post-reading三个部分。 Pre-reading以Silk Road为主题，输入背景知识，促进学生对Reading的深刻理解。Reading讲述了海上丝绸之路开辟的背景、发展和繁荣，文章的后半部分重点记叙了郑和下西洋的过程和意义。Reading的主题内容明确，此主题是培养学生民族自豪感的好材料。Reading的语言材料不难，但是由于文章所记叙的内容时间跨度很大，关系略显复杂，学生不易把握文章的结构。教学中处理好背景知识输入和读懂文章整体结构的任务设计，就基本可以很好地完成教学任务。Post-reading是对Reading内容的熟练和主题的拓展，最后一个任务升华了主题。这些任务设计都要求学生跨越段落寻找信息，因此教学设计中要适当补充和重新设计Tasks，以使得大多数学生都能读透文章。
1．3 SPEAKING 部分包括三个Situations。三个Situations都是以科学发现和探测为主题，提出问题情境，旨在培养学生对问题情境的判断能力和运用语言解决问题的能力。问题的情境设计具有思辨性特征，学习者只有对问题情境的深刻理解，才能做出准确的判断，在此基础上形成决策。
1．2 LISTENING包括Pre-listening, While-listening和Post-listening三个部分。Pre-listening的目的是培养学生听前预测的能力，这就使得听的过程目的性很强。Post-listening的两个任务设计各有侧重，任务1强调对听力内容的整体理解，任务2则侧重对话题思想的理解，重在培养学生解决问题的能力。整体上来看，Listening的设计旨在培养学生预测、选择、判断和深层加工信息的能力。
1．1 WARMING UP 以4位中外航海家的图片为引线，引出了本单元人物和话题。4个任务设计层层深入，首先由人物事迹逐渐导向单元话题——Exploration。最后一个任务把话题引向具体的单元话题的目标语言。
1． 教材分析
本单元的话题是Crossing limits，话题涉及的历史和地理知识庞杂，给学生理解文章带来了较大难度。Pre-reading, Reading和Post-reading部分涉及了许多背景知识，这会给学生精读文章带来障碍。Warming Up, Listening和Integrating Skills部分涉及到Exploration话题的空间跨度很大，因此解决好中外、过去和现在Exploration的关系可以促进学生理解话题——跨越极限。Speaking和Writing以判断和劝诱为主题，旨在通过理解和学习话题，发展学生理解观点和形成自主判断，促进学生的自主决策能力。
