Learning About Language—语法·提升语言能力 课时目标 1.开展“头脑风暴”，回顾已学词汇并适当拓展，构建一个以“标志性风物”为主题的词汇思维导图。 2.培养在相对复杂的语境中运用词汇的能力，巩固语篇知识、增强语篇意识。 3.复习非谓语动词中的过去分词，掌握其语法结构，并运用所学结构进行得体的口头表达。 语法项目——复习过去分词 初识语法——在美文运用中体悟　 Don't be ①worried, my friend. Follow the following advice I give you, and you may get your problem ②settled. First of all, what you must do is to smile at your classmates. A smile speaks louder about your wish to make friends than any words. Keep it in your mind that the colourful campus life ③created by yourself will make you feel at ease. Next ④absorbed in your hobbies, you will find that common interests are a shortcut to making friends.Having regained your confidence, you can make as many friends as possible. ①worried为worry的过去分词形式，在句中作表语； ②settled为settle的过去分词形式，在句中作宾语补足语； ③created为create的过去分词形式，在句中作后置定语； ④absorbed为absorb的过去分词形式，在句中作状语。 慧学语法——运用“形式—意义—使用”三维动态语法观　 过去分词通常是由“动词原形＋ed”构成的，部分动词的过去分词有不规则变化形式。过去分词无时态和语态的变化。及物动词的过去分词既表示被动，又表示完成；不及物动词的过去分词只表示完成，不表示被动。 一、过去分词(短语)作定语　 [先感知] ①(教材典句)Most of their musical instruments are really just sticks found on the ground. ②(教材典句)A skilled player can play for a long time without stopping to breathe. ③(2022·全国乙卷) It can help to build a community with a shared future for mankind. ④I think the scientific advances mentioned in your article are fantastic!
