设计了四个问题要求同学们对中国古代四个重要时期的人类生活的习惯进行讨论，包括他们所使用的工具，他们的饮食，房屋，及房屋内的装饰品以及他们的娱乐和不同时期具有典型代表的艺术品。

这部分的目的在于呈现本单元的中心话题——考古学，及引起同学门对考古学的兴趣，形成一个有关于考古学的信息包，对考古学及中国古代所取得的成就有初步的了解和印象，并引入相关的词汇。

“听力”（listening）部分提供了一段师生对话，要求学生在听的基础上完成细节，根据录音的描述绘画出古代所使用的工具的形状。

本部分的目标在于训练同学们获取细节知识的能力；另一方面有助于加强学生对古代所使用的工具的了解，进一步激发同学们对本单元中心——考古学的兴趣。

“口语”（speaking）部分结合本单元的中心内容，提供了为了获取有效信息，如何表达自己的愿望的句型，要求学生以双人对话的形式，按照例子，用所提供的句型和话题进行对话。

对考古学以及考古学的重要发现提出自己的意见和看法。

本部分的目的在于促进同学们对考古及考古学的思考，又促进同学在陈诉观点过程中的口头表达能力和语言组织能力。

“读前”（Pre-reading）部分提供了三个与本单元的主题有关的问题，通过启发学生对中国皇帝陪葬的猜测和思考，运用自己已有的文化背景知识和语言知识，来猜测英国史前巨石柱王的情况，并且通过阅读验证自己的猜测。

“阅读”（Reading）部分介绍了人类考古史上的一个重大发现the King of Stonehenge in England。

这个发现使得考古学家相信那个时期的人们已经和欧洲其他地区有贸易和文化交往。

“读后”（Post-reading）部分设计了三个问题。

第一题考察学生对文章内容的理解，要求学生在课文中找出在坟墓里挖掘出来的objects 和materials。

第二题要求学生根据课文信息找出青铜器时代的英国人民和欧洲其他国家和地区的文化和贸易交往。

第三题要学生讨论建造the Stonehenge所需的技术，科技，发明和工具。

“语言学习”（Language study）分词汇和语法两部分。

词汇部分提供了两组习题，第一题要求学生将词汇和解释相对应，考察学生对词汇的理解和区分能力。

第二题要求学生掌握同一单词的不同功能，让学生在语境中应用词汇。

语法项目是复习it作为形式主语，形式宾语，和在强调句中的用法。

本部分为学生安排了句型转换，情景操练，完成句子等练习，旨在使学生能自如地运用“it”。

“综合技能”（Integrating skills）部分由阅读和写作两方面内容组成。

阅读材料介绍了金沙和三星堆两个古文化遗址，旨在告诉世人我国拥有神秘而博大精深的文明。

通过对这两个遗址的发掘，对研究我国历史文化具有极其深远的意义。

写作部分让学生们讨论在发现古文物时，该做什么，不该做什么。

为写作埋下伏笔。

通过这些练习，学生不仅对文中提到的内容能够有进一步的理解，而且还能让学生对文物保护有更深的认识。

“学习建议”（Tips）部分提供了如何创作一张flow chart的步骤和资料，以帮助学生更好地完成“综合技能”的写作任务。

“复习要点”（Checkpoint）部分简要总结了本单元的语法重点——it作为形式宾语，形式主语和在强调句中的应用，并给出了一些例句，帮助同学举一反三。

同时通过让学生寻找能够描述文物发现的词汇，引导学生对本单元所学的词汇作一次小结。

Work in groups to talk about the inventions and kinds of science they must have had, based on the reading passage.Step V AppreciationShow some pictures of Stonehenge.What do you think of Stonehenge? (students maybe say that it is wonderful, beautiful, mysterious, etc.)Teachers should point out the fact:Construction took place in three phases, over 25 generations. Most of it was the result of human muscle and a system of ropes and wooden levers used to transport themassive stones. To drag the sarsen stones, weighing up to 45 tones, or the weight of six elephants, from Marlborough Downs, 30 kilometres to the south of Stonehenge, would have been quite a feat. The bluestones, in contrast, were about four tones but are believed to have come from much farther -- the Preseli Mountains nearly 385 kilometres away. Popular theory suggests the stones were rolled to the Welsh shore, carried on raft around the coast and into the River Avon, at Bristol. They would have then been transported through local rivers and then back to land, where they were once again rolled to Salisbury Plain.Then draw a conclusion:The construction of Stonehenge is a process of blood, sweat, and tears.Step VI. Discussion1.Why was the Stonehenge built or the purpose of the construction?The main theories of the purpose existed and accepted in the world today:Execution ground(刑场) space station（宇宙太空港）Hunting ground（狩猎场）an astronomical calendar（天文历法仪）temple（宗教寺庙）2.Suppose your hometown found an ancient grave, and some people suggestdigging it up, while others have different opinions.

Summary and homeworkIn this class, we’ve learnt about the King of Stonehenge by reading the passage and also learnt some useful expressions and sentence patterns. After class, you need to domore exercises to master them freely. Studying archaeological discoveries can help us learn about he life of people during different periods, so if you have time, go to visit the local museums or surf the Internet to learn more about archaeology. At last, don’t forget to prepare for the next period----language study. So much for today.Period 4 Language StudyGoals:1) revise some new words.2) Enable the students to recognize word form3) Enable the students to use “it”.Difficulty: “it” is used as the subject position taking the place of “to do”/ “a clause”.
