B1U5 Discovering Useful Structures 教学设计教学设计主题语境：人与自我主题语境：人与自我语言学习语言学习授课时长：一课时（授课时长：一课时（20 分钟）分钟）教学内容分析教学内容分析本单元的语法结构是关系副词 when、where、why 和“介词+which”引导的限制性定语从句。关系副词 when、where、why 引导定语从句时，可用“介词+which”替换，而本单元主要涉及“in/on/at/during+which”引导的定语从句。教学目标教学目标在本课学习结束时，学生能够：1.理解关系副词 when,where,why 和“介词+which”引导的限定性定语从句的基本形式、意义及功能；2.辨析并掌握关系副词与关系代词在用法上的区别；3.在特定的语境中准确及恰当地使用关系副词 when,where,why 和“介词+which”引导的限定性定语从句。教学重点教学重点学生通过观察、思考、对比、归纳，理解关系副词 when,where,why,和“介词+which”引导的限定性定语从句的基本形式、意义和功能，并掌握其基本用法。在此基础上，通过观察和对比，辨析关系副词和关系代词在用法上的区别。教学难点教学难点学生学会在特定的语境中（课中的 micro-writing 及课后的 writing task）准确及恰当地使用 when,where,why 和“介词+which”引导的限定性定语从句，以力求语言更丰富、准确，在提高英语语言组织能力的同时发展逻辑思维能力。教学步骤教学步骤步骤步骤教学活动教学活动设计意图设计意图环节用时环节用时1.Explore&Practice1.1 Basic forms and meanings of RRCStep 1Ss observe the four target sentencesfrom the reading passageand figureoutthebasicformsofrestrictiverelative clauses starting with relativeadverbs.关注形式关注形式：通过观察目标语句，找出由关系副词引导的限定性定语从句，对其基本形式和构成成分形成一个初步认识，落实教学目标 1。2 minsStep 2On top of that,Ss proceed to work outthe question:“What do when,where,whyand on whichrefer toin each sentence?”After that,a tip forthe basic usages of relative adverbs isgiven.关注意义：关注意义：思考关系副词的具体修饰对象，理解限定性定语从句的表意功能。在此基础上，归纳关系副词的基本用法，落实教学目标 1。2 minsStep 3Ss look at more examples,find outrestrictive relative clauses and identifythe meanings they communicate in eachexample.通过练习，巩固和内化所学：关注限定性定语从句的基本形式和意义。2 mins1.2 Basic functions of RRCStep 4Ss observe and compare the four targetsentences with their counterparts(in theform of simple sentences)and figureout the question:“Why does the authorchoose to use restrictive relative clausesinstead of simple sentences?”.关注功能：关注功能：通过与简单句对比，理解目标语法结构在整合信息，使语言更丰富、准确，简洁，提高英语语言组织能力等方面的功能，落实教学目标 2。2 minsStep 5Ss practise connecting simple sentencesby using restrictive relative clauses.通过练习，巩固和内化所学,运用限定性定语从句整合信息，使语言更丰富、准确，提高英语语言组织能力，简洁，为后续的micro-writing 作铺垫。2 mins1.3 Difference between the usages of relative adverbs and relative pronounsStep 6Ss tell the difference between relativepronouns and relative adverbs,which isillustrated by a flow chart.关注用法区别关注用法区别：关系副词和和关系代词在用法上的区别，落实教学目标 3。2 minsStep 7Based on Step 6,Ss finish somefollow-up exercises.通过 follow-up练习，巩固和内化所学：关系副词与关系代词的用法区别，落实教学目标 3。2 mins2.ApplyStep 8Micro-writing:Ss read an interview talking about aChinese students experiences oflearning English and finish task 1 and2.Task 1:rewrite the underlined partswith restrictive relative clauses.Task 2:complete the missing part byusing restrictive relative clauses wherenecessary.基于以上所学，结合特定的语境（一位准大学生的高中英语学习经历的访谈），在语篇中准确及恰当地使用目标语法结构：关系副词引导的限定性定语从句，力求语言更丰富、准确，在提高英语语言组织能力的同时发展逻辑思维能力，落实教学目标 4。6 minsAssignment:1.Read a passage talking about another persons experience of learning German andcomplete the missing parts with relative adverbs or relative pronouns.2.Write a paragraph of your experiences of learning English.
