Unit 4 Amazing Science Topic 3 Section A 课件 2025-2026学年仁爱科普版（2012）九年级英语上册

该初中英语课件围绕“中国航天”主题，聚焦定语从句（that/which/who）及航天词汇（manned spaceship, lunar probe等），通过中国载人航天任务时间线、嫦娥工程等真实情境导入，结合听力对话（如Michael和Kangkang在科技馆的交流）与信息总结表格，搭建“听说积累—语法讲解—练习应用”的学习支架，帮助学生从简单句过渡到复合句。 其亮点在于融合语言能力与文化意识培养，以神舟系列、嫦娥工程等真实任务为载体，设计信息总结表格（填写任务Name、What to do等）锻炼表达能力，通过四步合并法（找共同点、删重复点等）讲解定语从句，培养逻辑思维。学生在学习中提升跨文化沟通能力与家国情怀，教师可借助结构化素材优化语法教学效率。

火箭点火的瞬间，四个支撑架打开，载人火箭开始摆脱重力，缓缓上升。起飞约20秒后，游标发动机转动方向，使火箭向一侧倾斜，继续飞行。起飞两分钟后，为减轻重量，已无需要的逃生塔被抛向空中。此时助推器燃料也已用完，被抛弃后以旋转的十字形向下坠落，立即中央火箭继续加速。航天员们处于超重状态，身体重量是他们在地球上的3.5倍。飞行2分30秒后，火箭已飞出大气层，飞船保护罩已不需要而被抛弃。这时宇航员可以透过窗户看到美丽的太空飞行。五分钟后点火，二级火箭同时抛弃，一级火箭同时脱落，二级火箭发动机故障已露出发动机。飞行九分钟后，地面控制中心关闭三级火箭，并将它与载人飞船分离。此时，飞船内的毛绒玩具开始失重漂浮，表明飞船已到达预定轨道。现在，飞船的天线和太阳能电池板展开，以为飞船提供电力和动力，飞行轨道高度约为240公里，时速高达27000公里。之后，飞船进行速度微调，追上天宫空间站后，飞船将与空间站对接到此，载人飞船任务圆满结束。 On April twenty fourth nineteen, nineteen seventy, china launched its first man made satellite.

And I have a mere hair so I can kind of watch what i'm doing. Sometimes the water gets away from you, and you try and catch as much as you can. And I just worked . the water . up through to the end of my hair, and I take . my knowing shampoo and score IT also . on the sculp a little bit and relevant again. gonna working IT up to the end. And sometimes I actually . take my home to help . work with all the way to the end. And I like to take my tale while I have the shampoo o in . there and just kind of work IT. because without standing . underrunning water, you kind of need to use the towel a little bit to help get some of the dirt out.

I don't put IT back in a pony il while it's trying. And that is how washing hair in space on the international conditions. 中国空间站游泳池。 月球正在悄悄生锈，科学家发现这竟然是地球惹的祸几年前，月球表面惊现赤铁矿，但月球没有氧气，如何生锈？中国澳门科技大学通过实验模拟揭晓答案，原来月球生锈，地球背锅。每个月有几天月球会进入地球磁层尾部，地球泄露的氧离子趁机偷袭月球表面，同时太阳风、清流被地球阻挡，铁元素得以与氧结合，形成赤铁矿。更有趣的是，这种现象多发生在月球两极，说明地月之间可能已持续交换物质超过40亿年，地球一直在默默给月球送氧气，是不是很浪漫？ 也就意味着从2019年1月开始，玉兔二号服役六年多，仍然在工作当中，而它的设计寿命是三个月。这次拍摄的照片来自玉兔二号的桅杆全景相机。月球车位于月球背面南北45.42度，东经177点五六度。玉兔二号已经累计行驶里程超过了1640米。玉兔二号是随嫦娥四号一起着陆在月球背面的，开启了人类探测器首次在月球背面软着陆及巡视探测之旅。它长1.5米，宽1米，高1.1米，重约135公斤，采用六轮独立驱动的设计，能应对月面崎岖地形。六年多来，玉兔二号携带的全景相机拍摄了月球高分辨率的全景照片，帮助科学家了解月球背面的地形地貌。通过他的探测发现，月球背面的地质结构与正面有所不同，存在一些独特的岩层和矿物分布，为研究月球的形成和演化提供了新线索。它配备了测月雷达，在行驶过程中向月面下探测，获取了月壤的厚度以及浅层地下结构等信息。这些数据对于了解月球表面的物质循环以及月壤的形成过程具有重要意义。它还监测了月球表面的辐射环境、带电粒子等环境因素。可以说玉兔二号的探测填补了诸多科学空白，也展示了我国在深空探测领域的先进技术。这些技术经验为我国后续的月球探测任务点。
