U3 A 课时同步训练-Presenting ideas & Reflection-【初中必刷题】2026-2027学年八年级上册英语同步课件（外研版·新教材）

该初中英语课件聚焦八年级上册Unit 3“Make it happen !”主题，核心内容为如何在家制作气压计及通过其测量气压、预测天气的原理。课堂导入以“Home Lab#3”实验步骤（如制作橡胶盖、固定吸管指针）为引导，通过实验器材清单、步骤分解图示等学习支架，帮助学生衔接动手操作与科学原理，理解说明文体裁的语言逻辑。 其亮点在于融合科普实验与英语阅读，以268词的说明文（科普知识与现代技术题材）呈现实验过程，通过图示理解题（如步骤3线条绘制）和原理分析题，提升学生语言能力（说明性文本理解）与思维品质（实验逻辑分析）。采用“实验操作+阅读理解”的教学方法，学生能增强英语应用与科学探究能力，教师可借助同步训练资源高效开展课时教学。

Spread the left part. Pull it tight over the jar top. Press the balloon to make it smooth and tie it with a rubber band. Cut one straw end at 45° for a sharp point. Tape the straw’s other end to the balloon’s centre. Ensure it points straightly—it’s your “pointer”! 3 Draw the Lines _______________________________ Put an A4 sheet of paper in front of the straw’s sharp end. Mark the straw-pointing spot with a pencil.Use a ruler to make 4 lines each above and below this spot, 0.5cm apart. 续表 刷能力 返回目录 9 4 Name the Weather Signs Draw a sun next to the top mark, a cloud with raindrops next to the bottom mark. Place the whole device （装置） in a corner where it won’t be disturbed （打扰）. 5 Observe and Record Check straw position daily at set times, record where it points. If the straw points to the top mark, the weather will probably be dry and sunny. If it points to the bottom mark, it may rain. If it’s in the middle, it will probably stay the same. 续表 刷能力 返回目录 10 How it works： Warm air rising causes low pressure （common in rainy weather）, and inside air pushes the balloon lid （盖子） out, and then, the moving straw pointer goes down. Sunny days opposite.#3.4.1 阅读理解·语篇导读 本文介绍了如何自己在家做气压计以测量气压并预测天气。 刷能力 返回目录 11 1. 图示理解 Among all the following objects, which are needed in Step 1?( ) B A. B. C. D. 【解析】细节理解题。根据“Scissor off 1/3 of the balloon’s bottom. Spread the left part. Pull it tight over the jar top. Press the balloon to make it smooth and tie it with a rubber band.”可知，必须用到广口瓶、 气球、剪刀和橡皮筋。故选B项。 刷能力 返回目录 12 2. 图示理解 According to the underlined part in Step 3, which of the following pictures is correct?( ) D A. B. C. D. 【解析】细节理解题。根据“Use a ruler to make 4 lines each above and below this spot, 0.5 cm apart.”可知，用尺子在这个点的上方和下方各画4条 线，每条线相距0.5 cm。故选D项。 刷能力 返回目录 13 3.How does the barometer work on sunny days?( ) D A.Low pressure outside→Balloon lid out→Pointer up B.Low pressure outside→Balloon lid in→Pointer down C.High pressure outside→Balloon lid out→Pointer down D.High pressure outside→Balloon lid in→Pointer up 【解析】细节理解题。根据“Warm air rising causes low pressure （common in rainy weather）, and inside air pushes the balloon lid out, and then, the moving straw pointer goes down. Sunny days opposite.”可 知，雨天时暖空气上升导致低压，内部空气将气球盖推出，然后移动的吸管指针 下降，反之是晴天。故选D项。 刷能力 返回目录 14 4. 文章出处 In which section of a magazine can we read this passage?( ) A A.Science. B.Space. C.Sports. D.News. 【解析】推理判断题。根据“Let’s make your own barometer. Then you can measure air pressure at home and predict the weather yourself!”可推知， 我们可以在杂志的科学部分阅读这篇文章。故选A项。 刷能力 返回目录 15 $
