课文翻译大明：嗨，托尼。
在忙什么呢？托尼：大明。
我刚刚做完了我们学校项目要求的宇宙飞船模型。
大明：我还没有开始呢，真不知道怎么做，你能帮我吗？托尼：当然可以以，没问题。
你听说最新的消息了吗？科学家已向火星发射了一个航天器，它在太空中已经行驶了好几个月了。
大明：它到达火星了吗？托尼：已经到了，所以新闻才报道了嘛。
大明：那他们在火星上发现生命了吗？托尼：还没有。
大明：航天器上有宇航员吗？托尼：没有。
大明：为什么没有呢？宇航员都到过月球了。
托尼：是的，但是还没有人到过火星。
火星离我们很远，比月球远多了。
现在有好多科学家都在认真研究，希望有朝一日能将宇航员送往火星大明：有意思！我怎么才能找到有关太空旅行的信息呢？托尼：你可以到网上检索。
大明：我会的，谢谢你，托尼！科学家认为地球上的生命已有亿万年的历史然而，我们却没有在其它任何星球上发现生命地球是行星，围绕太阳运行围绕太阳运转的还有其他七颗行星没有一颗行星拥有与地球一样的环境，所以科学家认为其他星星上都不可能存在生命太阳和围绕它旋转的行星组成太阳系，我们的太阳系是一个更大的星群里的一部分，这个星群叫银河系，或者银河银河系里有无数颗恒星，我们的太阳只是其中一颗科学家已经在宇宙中发现了很多其他星系他们离我们很远，他们发出的光要在宇宙中经过很多年才抵达地球那么，宇宙到底有多大？我们无从想像科学家发射了航天器到火星上拍摄图片甚至发射航天器到太阳系以外进行探索然而，还没有任何航天器到达银河系里的其他恒星科学家们一直在问这些问题：宇宙中有这么多星球，只有地球上有生命吗？或者，宇宙中还有其他生命存在？是否有来自其他行星的人造访过地球？为什么没有任何人与我们联络过？目前我们还无从知晓这些问题的答案【重点短语】1. What are you up to? 你在干什么？2. the latest news 最新消息3. get information 获得信息4. search for 寻找，搜索5. in order to 为了6. much+比较级...得多7. on earth 在世界上，在人间，究竟，到底8. communicate with sb 与某人交流9. hundreds of 数以百计的10. go around 绕着......走11. billions of 数十亿的12. take photos 拍照13. send...to... 把...送到...14. no problem 没问题15. be far away（from) 离...远16. go online 上网17. search for 搜索18. more than 超过；多余19. look for 寻找20. look like 看起来像21. finish doing sth 做完某事【重点句型】1. 还没有人过去火星。
Module3Journeytospace大单元整体教案
1.理论介绍：首先，我们要了解太空探索的基本概念。太空探索是指人类利用航天器对地球以外的宇宙空间进行探索和研究。它是人类科技进步的重要标志，有助于拓展我们对宇宙的认知。
2.案例分析：接下来，我们来看一个具体的案例——阿波罗11号登月任务。这个案例展示了太空探索在实际中的应用，以及它如何帮助我们解决问题。
4.学习能力：激发学生探索宇宙的兴趣，培养自主学习、合作探究的能力，提高解决问题的能力。
三、教学难点与重点
1.教学重点
-词汇：本模块的核心词汇，如astronaut, spaceship, lunar module, alien, planet, solar system, gravity, space station等，是学生需要掌握的重点，以便于在讨论太空探索时能够准确表达。
四、教学流程
（一）导入新课（用时5分钟）
同学们，今天我们将要学习的是《Module 3 Journey to Space》中的“Visiting the moon”章节。在开始之前，我想先问大家一个问题：“你们是否想过成为一名宇航员，探索神秘的月球？”这个问题与我们将要学习的内容密切相关。通过这个问题，我希望能够引起大家的兴趣和好奇心，让我们一同探索太空的奥秘。
举例解释：
-在学习“Looking for life”单元时，难点在于如何使用一般现在时态描述外星生命的可能存在，如“Scientists believe that there may be aliens on other planets in the solar system.”
-在学习“Space travel”单元时，难点在于理解并使用一般将来时态来谈论未来的太空旅行，如“SpaceX plans to send people to Mars in the future.”
