语篇研读
WHAT
主题
属于 “语言知识” 范畴,聚焦由 as soon as 和 while 引导的时间状语从句的用法,是对时间状语从句知识的拓展。
内容
包含两个主要部分,一是让学生阅读句子并划出时间状语从句,圈出连接词,如 “A new type of smart walking stick for blind people can detect any object as soon as the person gets close” 等;二是让学生总结 as soon as 和 while 所表达的时间关系,还配有相关练习,如用单词云中的词语和表达造句,以及看图讲故事等
WHY
传递意义
通过学习这两种连接词引导的时间状语从句,帮助学生更准确地描述事件发生的时间关系,提升语言表达的丰富性和逻辑性,为理解更复杂的语篇和进行更流畅的交流奠定语法基础。
HOW
文体特征
属于语法讲解与练习类文本,以规则阐述、例句分析和练习巩固为主,语言简洁、严谨,逻辑性强。
内容结构
按照 “例句感知 — 规则总结 — 练习巩固 — 综合运用” 的顺序展开,先让学生通过例句初步感知语法现象,再总结规则,最后通过不同形式的练习强化运用,符合语法学习的认知规律。
语言特点
包含用于引导时间状语从句的关键连接词 as soon as 和 while;例句多结合数字技术相关语境,如智能手杖、机器人等,使语法学习与单元主题相联系。
学情分析
学生在之前的学习中已对时间状语从句有初步接触,了解一些基本连接词的用法,但对于 as soon as 和 while 引导的时间状语从句的具体用法及所表达的时间关系理解不够清晰。他们在造句和叙事时,容易混淆这两个连接词的用法,且在从句位置摆放和时态配合上容易出现错误,需要通过具体练习加以巩固。

导入
Look at pictures of two actions happening (e.g., a robot sending video information while firefighters making a plan; a smart walking stick detecting an object as soon as a blind person gets close).
Discuss in pairs:
What is happening at the same time?
What happens immediately after another action?"
观察学生能否描述图片中动作的时间关系,评估其对 “同时发生” 和 “立即发生” 的认知。
结合单元主题相关场景,激活学生对不同时间关系的感知,为学习新语法点铺垫。

Read the sentences in 1 (1-171, 1-172).
Underline the adverbial clauses of time and circle the linking words (as soon as, while).
Then discuss: "What do these clauses describe?"
检查学生能否准确划出从句和连接词,评估其对新语法现象的初步识别能力。
让学生通过例句直观感知 as soon as 和 while 引导的时间状语从句,明确学习对象。
Work on 2 (1-173).
Match as soon as and while with their time relationships: "One thing happens immediately after another is complete" and "Two actions happen at the same time".
查看学生的匹配结果,评估其对连接词所表达时间关系的理解程度。
帮助学生明确 as soon as 和 while 的核心含义,为正确运用奠定基础。
练习
Do 3 (1-180).
Make sentences with words from the word cloud (e.g., 3D printer, laptop, while, as soon as).
Each sentence must contain as soon as or while.
检查学生所造句子是否正确,评估其对连接词用法的初步运用能力。
通过模仿练习,让学生初步尝试运用所学连接词造句,强化语法规则。

巩固
Complete the following sentences with as soon as or while: "______ the robot is moving, it sends video information." "The smart watch will call for help ______ it detects an emergency."
检查学生填空的正确性,评估其对连接词的辨析和运用能力。
进一步巩固学生对 as soon as 和 while 用法的掌握,区分不同时间关系。
