To compare distances between the Earth and other stars. Read the title and the text quickly. Where would you find an article like this? Reaching for the Stars Since the beginning of human history, people have looked up at the stars and wondered what they were like. Many ancient cultures believed that these points of light were from gods or other mysterious worlds. However, as science and technology developed, we learnt the truth about stars. They are real places like our own sun, and they are farther away than anyone imagined. This raises the question: Can we visit the stars one day? The man-made object which has travelled farthest from Earth is Voyager 1. This spacecraft was launched in 1977. In case Voyager 1 is found by alien life, a special record with sounds and pictures from Earth is carried on board. It shows who we are and where we are from. By 2025, Voyager 1 was over 25 billion kilometres from Earth, but that is still a long way from Earth's second-closest star, Proxima Centauri. That star is 4.2 light years away — about 40 trillion kilometres! Read the title and the text quickly. Where would you find an article like this? The challenge of visiting the stars gets even bigger for space flights with humans. The farthest that any human has travelled in space is only about 400,000 kilometres, to the far side of the moon. Time is a big problem. At present, even a journey to the planet Mars will take around six to nine months. What will the astronauts eat and drink during this period? And how about their health and safety? These problems grow when we talk about visiting another star. It might take hundreds of thousands of years to get there! Scientists, however, believe that visiting the stars is not a completely wild dream. One idea is to have the astronauts sleep during their journey, like some animals do in winter. Another is to develop much faster spacecraft. While this is not possible right now, with nations and scientists cooperating with one another, there is hope that the necessary technology will be developed. Humans have photographed other galaxies, set foot on the moon, and even successfully landed rovers on Mars. It seems likely that one day we will reach the stars. Read the title and the text quickly.

Taking more food and finding new planets first. Think and Share. 1. What is one big problem for humans to visit other stars? The huge distance is a big problem. It will take hundreds of thousands of years to get to another star. Besides, astronauts' food, health and safety are also serious problems. 2. Why does the writer think humans may reach the stars one day? Because nations and scientists are cooperating with each other. Humans have already made great achievements in space, such as setting foot on the moon and landing rovers on Mars. We hope new technology will be developed in the future. Discuss the questions. Find more information to support your answers. 1. What did some ancient cultures think about the stars? Why? Some ancient cultures believed that stars were from gods or other mysterious worlds. The reason is that they knew little about science and technology at that time, so they explained the unknown stars with myths and beliefs. 2. What is carried on board by Voyager 1? Why? A special record with sounds and pictures from Earth is carried on board. The reason is that in case Voyager 1 is found by alien life, this record can show who we are and where we are from. Discuss the questions. Find more information to support your answers. 3. What is the farthest trip that a human has travelled from Earth? Do you know any details about it? The farthest trip that a human has travelled from Earth is to the far side of the moon, about 400,000 kilometres. This record was set in April 1970, when an oxygen tank explosion forced the Apollo 13 crew to loop around the far side of the moon. 4. What do you think about the future of space exploration? I think the future of space exploration is very hopeful. With the development of science and technology, and international cooperation, we can expect more exciting discoveries and explorations in space. 04 Vocabulary mysterious adj.神秘的，难以解释的，诡秘的 例句：There are many mysterious things in outer space. 外太空存在很多神秘的事物。 a mysterious place 一处神秘的地方 a mysterious stranger 一位神秘的陌生人 mysterious power 神秘的力量 mysterious events 离奇神秘的事件 mystery n. 神秘，奥秘，谜 solve a mystery 解开谜团 mysteriously adv. 神秘地，莫名其妙地 易混辨析：mysterious /magical/secret mysterious：侧重“神秘的，难解的”，事物原因、真相不为人知，让人感到好奇、疑惑，不一定带有魔力。可以形容事件、地点、人。 magical：“有魔力的，奇妙的”，侧重奇幻、魔法般的，带给人美妙梦幻的感觉。 secret：“秘密的”，侧重人为刻意隐瞒、不打算告诉别人。 in case 以防，以备，万一，假使 例句：Take some water in case you get thirsty. 带上一些水，以防你口渴。 拓展短语：in case of + 名词 / 代词 万一，倘若 in that case 如果那样的话 易混辨析：in case /in case of /in any case /in no case in case + 完整句子：以防，万一（接从句） in case of + 名词 / 名词短语：万一……，后不能接句子。 in any case：无论如何，不管怎样 in no case：决不（放句首句子要部分倒装） 易混辨析：in case /if in case：预防，“以防某事可能发生”，这件事不一定会发生。 if：如果，引导条件，假设事情发生之后，再做后面动作。 考试易错提醒：in case 从句不用 will 表将来，使用一般现在时代替将来。 completely adv.完全地，彻底地 例句：I completely agree with your opinion. 我完全同意你的观点。 completely different 完全不同 completely forget 彻底忘记 completely change 彻底改变 completely wrong 完全错误 complete adj. 完整的，完全的，全部的；v. 完成，使完整 completion n.完成，结束 易混辨析：completely /entirely/totally completely：侧重“彻底地”，强调事物达到完全的状态，常修饰形容词、动词，可用于否定含义。 entirely：侧重“全部地”，强调整体，把事物当作一个完整整体来看待，书面色彩略重。 totally：口语使用频率很高，强调“全然、简直”，主观语气更强。 💡易错提示：complete 是形容词 / 动词；completely 是副词，修饰动词、形容词。 cooperate v.合作，协作，配合 cooperate with sb 与某人合作 cooperate in (doing) sth 在某事上合作 cooperate to do sth 合作去做某事 cooperation n.合作，协作 in cooperation with… 与…… 合作 cooperative adj. 合作的；协作的 n. 合作社 a cooperative team 善于协作的团队 易混辨析：cooperate /work together /collaborate cooperate：正式用词，侧重互相配合、协同行动，为共同目标通力合作，可用于人、组织、国家，考试高频。 work together：普通口语表达，含义就是“一起工作”，口语化，没有 cooperate 正式。 collaborate：较正式，多指科研、艺术、创作方面的协同合作，共同产出成果。也可表示勾结（贬义）。 要点提示：cooperate 是不及物动词，不能直接接宾语。 imagination n.想象力，创造力，想象，空想，幻想出来的事物 例句：Space exploration needs plenty of imagination. 太空探索需要丰富的想象力。 have a good imagination 想象力丰富 have no imagination 缺乏想象力 use one's imagination 发挥想象力 beyond imagination 超乎想象 imagine v. 想象，设想 imagine sth 想象某事 imagine doing sth 想象做某事 imagine that‑clause 想象... imaginative adj. 富有想象力的（形容人） imaginary adj. 虚构的；假想的（形容事物） 易混辨析：imagination /fantasy imagination：中性词，指人的大脑的想象能力，可以用于科学创造、艺术创作，也可以指幻想。既可以产出现实可行的想法，也可以是空想。 fantasy：多指脱离现实的幻想、白日梦，常常难以实现，偏虚幻。 高频考点提醒：动词 imagine 后面固定搭配imagine doing sth，❌imagine to do。 expectation n.预料，期待，期望，指望，盼望 meet /live up to one's expectations 达到某人的期望 beyond (one's) expectations 出乎意料 against all expectations 完全出乎意料 in expectation of 预料到；期待着 expect v.预料；期待；指望 expect sth 期待某事 expect to do sth 期待做某事 expect sb to do sth 期待某人做某事 expected adj. 预期的；预料之中的 unexpected adj. 出乎意料的 易混辨析：expectation /hope/wish expectation：侧重基于现实做出的预料、预估，心里认为某事大概率会发生；也可指对他人的要求期待。搭配：expect to do /expect sb to do hope（名 / 动词）：主观的希望，渴望好事发生，但没有十足把握。搭配：hope to do；hope that‑从句；不能说 hope sb to do wish（名 / 动词）：愿望，多指很难实现的空想；也常用于祝福。搭配：wish sb sth；wish to do；wish that（从句常用虚拟语气） cooperate with 与……合作，和……协作，配合某人 例句：Several space agencies cooperate with one another. 多家航天机构互相开展合作。 拓展相关搭配：cooperate in sth 在某方面合作 cooperate to do sth 合作做某事 易混辨析：cooperate with /work with /team up with cooperate with：偏正式书面用语，强调为共同目标主动协作、配合，多用于国家、机构、科研等正式任务。侧重协同完成较重大的事情。 work with：普通通用表达，含义宽泛：和……一起工作；共事。可以是简单共事，不一定强调 “齐心协力合作” 这个目的，口语书面都常用。 team up with：口语化短语，多指临时组队、结成搭档一起做事。 易混辨析：cooperate with /collaborate with cooperate with：普通正式“合作、配合”，中性，范围广，国家、团队、日常任务等都能用。 collaborate with：侧重科研、文艺创作方面合作共创成果；也可贬义表示“勾结”。 set foot on 踏上，登上，进入（某地） 例句：Humans first set foot on the moon in 1969. 人类于 1969 年首次登上月球。 拓展变体：set foot in + 场所（多为封闭空间、国家城市）踏入，进入 易混辨析：set foot on /step on /land on set foot on：强调人踏上、登上某块陆地、星球，侧重“抵达、来到这片土地” 这个经历，带有感情色彩。主语一般是人。 step on：踩在……上面；踩到。侧重脚踩在物体表面这个动作，不一定是抵达某地。 land on：（人、飞行器）降落于、着陆于。主语可以是人，也可以是飞船、航天器，强调降落这个过程。 ⚠️易错提醒 ❌ set feet on（错误） ✅ set foot on（固定，foot 单数） 否定常用搭配：never set foot on…从未踏上…… 05 Homework Review the words learned in this class.
