Unit 1 第4课时 Section B (1a-2b)（教学课件）英语鲁教版五四学制2024七年级上册

Why do we have different time zones? Our earth rotates on its own access. Due to this rotation, different parts of the year received different amounts of sunlight, thus causing morning, good evening and night. Now, if we had one time zone, then twelve ym would be new. Next some places, but IT would be night or evening at other places, which would be in convenient. Hence, scientists made different time zones according to the earth rotation with respected the sun. But how the . earth makes one, four, three hundred and sixty degree rotation in twenty four hours, this means in one hour the earth moves by fifteen degrees. Using this information, scientists divided the planet into twenty four sections or times. Each section or region was about fifteen degrees wide and had a specific standard time. This helps us know the proper time of the day in that part of the year. 什么是时区？由于地球自西向东自转，东边会比西边先看到太阳，这就导致东边的时间比西边的时间要早。如果把当地经线的时间作为当地时间，就会给人们的生活带来不便。为了克服时间上的混乱，1884年在华盛顿召开的一次国际经度会议上规定将全球划分为24个时区。英国格林尼治天文台旧址为中时区，又称临时区，东意到十二区，西1到12区，每个时区横跨经度15度，时间正好是一小时。最后的东西第十二区各跨经度7.5度，以东西经180度为界，每个时区的中央经线上的时间就是这个时。区内统一采用的时间称为区时，相邻两个时区的时间相差一小时，我国东西相跨五个时区，为了节约公共资源，方便工作和管理，我国采用首都北京所在的东八区的区时北京时间作为全国统一使用时间。 null Here and Now Section B 1a-2b UNIT 1 01 情 景 导 入 03 应 用 实 践 05 回 顾 总 结 07 随 堂 小 练 02 学 习 理 解 04 迁 移 创 新 06 考 点 速 递 08 家 庭 作 业 Contents Learning Objectives 1.能够通过观察重庆、内罗毕、纽约的城市图片和时钟图，理解三个城市的时间差异，并能根据这些线索对不同城市的人们的生活作出合理猜测。（学习理解） 2.能够通过感知三座城市的生活片段，发现不同国家不同地区人们生活的相似和不同之处，表达自己的兴趣，理解生活的意义所在。（应用实践） 3.能够正确运用现在进行时来描述公园图片中不同人物正在进行的活动。能够模仿阅读文本撰写视频脚本，有条理地描述周日公园的生活片段。能够以全球视野看待世界、思考问题，主动了解不同国家、不同地区的生活和文化。（迁移创新） 01 情景导入 Scenario import How do we share our lives with others?

Lavf58.29.100 Packed by Bilibili XCoder v2.0.2 Lavf59.14.100 $$踏上肯尼亚首都内罗毕，你准备好迎接一场自然风光、历史文化和现代文明交织的奇妙之旅了吗？内罗毕这座位于肯尼亚中南部的城市，东非高原的绿意盎然，让人仿佛进入了一个天然氧吧。街道两旁绿树成荫，城市各处公园绿地遍布，悠闲的生活节奏和人们的热情友好让人倍感宁静和谐。来到内罗毕，怎能不体验自然风光？内罗毕国家公园，世界上唯一一个位于首都城市内的野生动物保护区，狮子、大象、犀牛、长颈鹿等野生动物在这里自由奔跑，展现大自然最真实式的一面。国歌里亚湖的火烈鸟，粉红色的羽毛在阳光下熠熠生辉，构成了一幅美丽的画卷。除了自然风光，内罗毕的文化底蕴同样深厚。肯尼亚国家博物馆收藏了丰富的文物和艺术品，让人仿佛穿越时空与古人对话。肯尼亚柏马斯民俗文化村重现了肯尼亚传统村落的风貌，游客可以亲身体验肯尼亚的民俗文化和手工艺制作。当然提到内罗毕，不得不提的就是这里的美食，烤肉、海鲜、咖啡等地道美食让人回味无穷，carnivore烤肉餐厅的摆寿宴更是让人大饱口福。Karen likes on coffee、garden and咖啡的咖啡和环境更是让人流连忘返，是走出非洲忠粉们的必打卡之地。在住宿方面，内罗毕同样提供了多样化的选择，豪华的五星级酒店到经济实惠的旅馆和民宿应有尽有。我选择的内罗毕塞利纳酒店位于交通便利的基利马尼区，设施齐全且服务周到。游泳池和水疗中心更是让我在紧张的行程中得到了充分的放松和恢复。这次肯尼亚内罗毕之旅你收获了哪些美好回忆呢？快来评论区分享你的旅行故事和感受。 nullnull令人头疼的时差。现在是几点了？现在是5点30分，现在是11点30分，我这现在是0点30分. 现在几点了？为什么在地球上会出现这么多答案？难道时间不是一致的吗？这就是那个让很多人头疼的问题，时差。当然我可以保证，如果没有时差的设定，会有更多的人头疼。要想弄清楚这个问题，首先要知道我们每天都要关注的时间是怎么设定的。由于地球大多数地区天亮和天黑的时间是随着季节而改变的，比如在北京夏天天亮得早黑得晚，冬天则正好相反。所以我们把太阳经过某地天空的最高点时定为此地的地方时12点。当太阳再一次经过某地天空的最高点时，时间过去了24个小时。那么我们按照地球自转来计算一下，大概是每小时自转15度，也就是说经度每间隔15度，地方时相差1个小时，每间隔一度时间差四分钟，这就是时差。那么时差怎么计算呢？1884年在华盛顿召开国际经度会议时，为了克服时间上的混乱，规定将全球划分为24个时区，相邻15度经线内所用的同一时间是区时。比如北京所在的东八区就是从东经112.5度到东经127.5度，采用东经120度的地方时为区时。全世界所用的同一时间是世界时。零度经线的地方时，各地的标准时间为格林威治时间GMT加上或减去时区中所标的小时和分钟数时差。两个地区的时差可以采用同区相减，异区相加的方法，即两地同为东时区，西时区则相减。一个东西时区，另一个西东时区则相加。东时区的时间总比西时区要早，东时区的数值越大，时间越早，西时区的数值越大越晚。例如，北京属于东八区，纽约处于西五区，两地的时差是13小时，北京比纽约要早13个小时。如果是美国实行夏令时的时期，则相差12小时。大多数国家会在国内使用统一的标准时间，比如我国使用标准时间的就是北京时间。这就会出现一些有趣的现象，北京的同学们在早晨八点钟上第一节课时，而在我国西部，新疆同学才刚刚起床，他们将会在上午十点钟上第一节课。不要羡慕新疆的同学们，其实那就是新疆地区地方时的八点，他们在晚上还要晚睡觉。
