Unit 1 Learning About Language—语法·提升语言能力 （语法项目—非限制性定语从句）（课件PPT）-【新课程学案】新教材2022-2023学年高中英语选择性必修第一册（人教版2019）

Learning About Language—语法·提升语言能力 课时目标 1.巩固课文出现的重点课标词，在语境中理解单词的意义和功能，感知所填单词和前后单词之间的搭配关系，加深对语用的理解。 2.学会派生词的构词方法、特征和意义，并能运用目标词及其派生词描述卓有成就的人物。 3.掌握非限制性定语从句的语用功能，并能结合语境正确使用定语从句进行表达。 语法项目——非限制性定语从句 初识语法——在美文运用中体悟　 　　　 Nat, ①who was ten years old, lived in a small town in England.He always stayed in England for his holidays, but one day he decided to go to Spain, ②where all his friends liked to go for their holidays.First he went to Madrid, ③which is the Spanish capital, and stayed in a small hotel.On the first morning, he wanted to go out for a walk.④As we all know，in England, people drive on the left.But in Spain, they drive on the right, ⑤which he forgot.He put off the outing until next Sunday, ⑥when his friend wouldn't be so busy. ①who引导非限制性定语从句，修饰先行词Nat； ②where引导非限制性定语从句，修饰先行词Spain； ③which引导非限制性定语从句，修饰先行词Madrid； ④As 引导非限制性定语从句，指代后面一句话的内容； ⑤which引导非限制性定语从句，指代前面一句话的内容； ⑥when引导非限制性定语从句，修饰先行词next Sunday。 慧学语法——运用“形式—意义—使用”三维动态语法观　 一、限制性定语从句与非限制性定语从句的区别 [先感知] ①(教材P2典句)In the beginning, Tu Youyou went to Hainan, where malaria was more common, to study malaria patients. ②(教材P3典句)This medicine, which was called artemisinin, soon became a standard treatment for malaria. ③(教材P3典句)Later, the medicine was tested on malaria patients, most of whom recovered. ④In the last 500 million years, there have been five times when life on Earth has almost ended. ⑤This is the house which we bought last month. [会发现] 句是非限制性定语从句； 句是限制性定语从句。 ①②③ ④⑤ [明规则] 1．外在表现形式不同 限制性定语从句因与先行词关系密切，所以不可以用逗号将其与主句隔开；而非限制性定语从句与先行词关系不十分密切，所以可用逗号将其与主句隔开。 2．在句中作用不同 (1)限制性定语从句对被修饰的先行词有限定制约作用，使该词的含义更具体、更明确。限制性定语从句不能被省略，否则句意就不完整。 (2)非限制性定语从句与先行词的关系不十分密切，只是对其作一些附加说明，不起限定制约作用。如果将非限制性定语从句省去，主句的意义仍然完整。 3．关系词不同 关系词that和why可用于限制性定语从句中，通常不用于非限制性定语从句；在限制性定语从句中，关系词有时可省略，而在非限制性定语从句中关系词不能省略。 4．关系代词指代不同 限制性定语从句的关系代词一般指代一个名词或代词；非限制性定语从句的关系代词则既可指代一个名词或代词，也可以指代整个主句。　 [对点练] (1)单句语法填空 ①This is the place he used to live. ②Mr Zhang, came to see me yesterday, is an old friend of mine.
