Unit 5 Humans and nature Lesson 1 a sea story 语法教学设计-2023-2024学年高中英语北师大版（2019）必修第二册

教学设计 课题： Uni5 Lesson 1 grammar 主要内容 1、 课标 教学目标 关系副词引导的定语从句 重难点：关系代词与副词引导定语从句区别 2、本班学生学情：语法基础薄弱，不能识别定语从句 3、情景引入设计：复习关系代词定语从句 4、自探内容 下列句子，体会定语从句的用法。 ①But it was also a time when there were many great philosophers. ②Ancient China was a place where states were often at war with each other. ③Do you know the reason why he has been late? 发现：句中黑体部分的引导词是关系副词，分别在定语从句中充当时间、地点、原因状语。 5、合探内容 1）when引导的定语从句 I still remember the day when we met for the first time. 我仍然记得我们第一次相遇的那一天。 发现：是指时间的名词，如：time, day, year, month, moment, week, hour, minute等，when在从句中作时间状语。 2）where引导的定语从句 After living in Paris for fifty years he returned to the small town where he grew up as a child. 在巴黎生活了50年后，他回到了儿时成长的那个小镇。 发现：先行词是指地点的名词，如：place, factory, farm, station, town, meeting－room等，where在从句中作地点状语。 特殊情况： Today we’ll discuss a number of cases where beginners of English fail to use the language properly.(先行词是cases) 今天，我们将讨论一些英语初学者对英语使用不当的例子。 He wants to find a job where his skills can be put to good use.(先行词是job) 他想找一份能将他的技能派上用场的工作。 发现： 先行词表示抽象的地点或带有地点的意味且在从句中充当类似于地点状语的作用时，定语从句用where引导。 3）why引导的定语从句 We didn’t know the reason why he refused our help. 我们不知道他拒绝我们帮助的原因。 发现： 行词是reason时，定语从句的引导词需根据定语从句缺少的成分而定，如果缺少状语，用why；如果缺少主语或宾语，则用that/which。 关系副词可代替的先行词是时间、地点或原因的名词，在从句中作状语。定语从句中的关系副词有三个：when, where和why，它们在定语从句中分别作时间、地点和原因状语。 上述三个关系副词很多情况下都可以用介词＋关系代词来替换。where＝in/at/to＋which；when＝in/on/at＋which；why＝for＋which。 [巩固内化1]　单句语法填空 ①I can never forget the day when I first saw you. ②He came at the time when we needed him most. ③I’ll never forget the days that/which we spent together. ④Almost every teenager will experience a period in their life when they aren’t satisfied with their parents. ⑤We live in an age when more information is available with greater ease than ever before. 6、课堂小结 语法填空 ①The accident has reached to the point where both their parents are to be called in. ②You would get into a situation where you have to decide immediately. ③The next day, my brother and I went to the beach where we watched
