长难句分析教案
一、教学目标:
1. 帮助学生掌握英语长难句的基本分析方法。
2. 使学生能够识别并理解长难句中的主干和修饰成分。
3. 提升学生的阅读理解能力,特别是在处理复杂句子结构时的能力。
二、教学重点:

2.掌握长难句分析的方法:找主干和括号法。
三、教学难点:
1. 如何快速准确地找出长难句的主干。
2. 如何运用括号法将修饰部分清晰地区分出来。
四、教学过程:
Step 1 Reviewing and thinking
1. 回顾英语的五大基本句型和三大句子结构。
2. 观察并思考
是什么让句子变得又长又难?
句子修饰成分:“三长两短两语”_________________________________________
“一并列”____________________________________________
【设计意图】:通过回顾英语句子结构和句型,激活已知,为下文分析句子铺垫。同时,通过观察感知长难句的构成特点。
Step 2. Explanation
长难句分析的微技能方法:① 找主干 ②括号法
(一)找主干
1. 讲解找主干的方法:先找出句子中的所有动词,然后往前找是否有并列连词或引导词,最后顺藤摸瓜找出主语、宾语等主干成分。
示例分析:利用PPT上的例句进行演示,如We’ll explore beautiful park sites while (we are) conducting invasive plant removal, winter planting, and seed collection.[2024新课标I卷阅读理解A篇]
2. 通过教师演示、小组合作并展示找句子主干过程,指导学生思路方法:
1 [2024新课标I卷阅读理解C篇]According to this theory, people approach digital texts with a mindset suited to social media, which are often not so serious, and devote less mental effort than when they are reading print.
步骤:①找出所有动词 ②往前找是否有并列连词或者引导词 ③顺藤摸瓜
主干是:__________________________
② [2024新课标I卷阅读理解D篇]Using a global dataset of 1.9 billion records of plants, insects, birds, and animals, Daru and his team tested how well these data represent actual global biodiversity patterns.
主干是:__________________________
3. 练习巩固。
【设计意图】:通过教师讲解—演示—团队合作学习—个人练习的模式,让学生逐步掌握找主干的方法。
(二)括号法
1. 介绍括号法的定义和步骤:将修饰部分用括号括起来,使句子结构变得清晰。先找连词明句子,再做标记明主干,然后进行直译(先主干后修饰),最后调整语序。
2. 识别“三长”“两短”“两语”“一并列”修饰成分
3. 括号法应用示例分析:利用PPT上的例句进行演示:
Biodiversity apps can use our study results to inform users of oversampled areas and lead them to places — and even species — that are not well-sampled.
并列连词是_____, 并列部分是__________ 和__________, ______ 和______
该句是( )简单句( )并列句 ( )复合句
做标记:将修饰部分用括号括起来。
主干是:________________________________
翻译句子:_______________________________________________________
4. 小组合作括号法分析句子:
The goal of this book is to make the case for digital minimalism (数字极简主义), including a detailed exploration of what it asks and why it works, and then to teach you how to adopt this philosophy if you decide that it’s right for you.
5. 真题练习:
①阅读理解:“Quite a lot,” Daru explained. “Biodiversity apps can use our study results to inform users of oversampled areas and lead them to places — and even species — that are not well-sampled. To improve the quality of observational data, biodiversity apps can also encourage users to have an expert confirm the identification of their uploaded image.”
What is Daru’s suggestion for biodiversity apps?
A. Review data from certain areas. B. Hire experts to check the records.
C. Confirm the identity of the users. D. Give guidance to citizen scientists.
②语法填空:Further, the Silk Route Garden around the greenhouse _60_______ (walk) visitors through a journey influenced by the ancient Silk Road, by which silk as well as many plant species came to Britain for __61(the)__ first time.
