Unit2 第2课时 Reading（课后作业）-【教与学·学导练】2025-2026学年八年级上册英语同步课件（沪教版·新教材）

该初中英语课件聚焦“数字（零）的文化内涵与应用”核心知识点，通过汉译英句子填空复习词汇语法，自然过渡到阅读文本，从零的历史起源（印度数学家发明符号“0”）到日常多场景含义（体育比分、冰点温度等），搭建“词汇-语篇-应用”的学习支架，帮助学生衔接前后知识。 其亮点在于融合语言能力与思维品质培养，设计词义猜测（如“struggled”释义）、细节提取（“zero degrees Celsius”含义）等阅读任务，引导学生分析推理。同时结合生活实例（二进制代码、“starting from zero”习语）渗透文化意识，学生能提升语言理解与表达能力，教师可借助结构化练习与语篇素材优化教学流程。

Around 500 AD，Indian mathematicians first created the symbol“0” to represent“nothing”. Before zero，people struggled to explain empty places in numbers. For example，the difference between 5 and 50 was unclear without zero. Today，zero is important in maths，science and technology. Without it，computers，calculators，and even smartphones could not work in the correct way. 教与学 学导练 英语 八年级 上册 配上海教育版 In daily life，zero has many meanings. In sports，a score of zero means no points earned. In weather reports，zero degrees Celsius is the temperature at which water freezes. Some people think zero means“nothing important”，but scientists and engineers know it holds great power. For example，zero helps create the binary code (二进制代码)，which runs all digital devices. Zero also appears in idioms. Phrases like“starting from zero” mean beginning with no advantages. Despite its simple shape，zero shapes our modern world in big ways. 教与学 学导练 英语 八年级 上册 配上海教育版 (　 　)1.
