Lesson 1: Focus On Language—语法·提升语言能力 课时目标 1.正确理解定语从句在句中的作用。 2.了解各种关系代词的功能。 3.掌握关系代词引导定语从句的用法，并能够在真实语境中运用。 语法项目—— Relative Clauses (1) 初识语法——在美文运用中体悟　 Lucy is my friend ①who/that has a hearing problem.When she first came to my school, she seemed lonely, but we soon became friends.At first it was difficult to communicate with her.So I learnt a new language ②which/that allows me to “speak” with my hands. Lucy is a smart girl ③whose ideas are always inspiring.I sometimes have problems ④which/that I can't solve.When this happens, I always ask Lucy for help.Lucy is a good listener ⑤who/whom/that I enjoy sharing moments of my life with. ①who/that引导定语从句，修饰先行词my friend，指人，在从句中作主语； ②which/that引导定语从句，修饰先行词 a new language，指物，在从句中作主语； ③whose引导定语从句，修饰先行词a smart girl，指人，在从句中作定语； ④which/that 引导定语从句，修饰先行词problems，指物，在从句中作宾语，可以省略； ⑤who/whom/that引导定语从句，修饰先行词Lucy，指人，在从句中作宾语，可以省略。 慧学语法——运用“形式—意义—使用”三维动态语法观 定语可以由形容词、名词、代词、数词、分词、不定式(短语)以及介词短语等来担任，也可以由一个句子来担任。在主从复合句中修饰某一名词、代词或整个句子，担任定语功能的从句，叫作定语从句，它所修饰的名词或代词叫作先行词。 一、引导定语从句的关系代词及用法　 [先感知] ①(教材P30典句)When we weren't playing on the court which was next to our building, we were watching a game on TV. ②(教材P30典句)Paul didn't know he'd soon get the chance that he'd been waiting for. ③(教材P31典句)And clearly, all the extra hours that he'd spent practising alone paid off. ④(教材P30典句)Paul's favourite player was Tyrone Bogues, a guy who played for the Charlotte Hornets, although we actually agree that they are both champions. ⑤(教材P30典句)Everyone knew Paul had real skills, and was someone who worked really hard and had a strong desire to play for the team. ⑥(教材P30典句)This week, The Lions were playing our main competitors, The Bears, a team whose record this season had been perfect.
