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? 15 Read the text. 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! 16 Read the text. 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! 17 Read the text. 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. 18 Language Focus 01. since the beginning of human history 自古以来 = since ancient times | 例：Since the beginning of human history, people have looked up at the stars with awe. 02. look up at 仰望 例：She looked up at the twinkling stars and wondered what secrets they held. 03. wonder what... be like 想知道……是什么样 例：I often wonder what life on Mars will be like for future generations. 04. as science and technology developed 随着科技发展 = with the development of science and technology | 我们探索宇宙的能力也在不断增强。 05. learn the truth about 了解……的真相 例：After years of research, scientists finally learnt the truth about the origin of the universe. 06. raise the question 提出问题 例：This strange phenomenon raises the question: Are we alone in the universe? 07. in case 以防万一 例：Take a fully charged power bank with you in case your phone runs out of battery. 08. on board 在船/飞机/航天器上 例：There are currently seven crew members on board the International Space Station. Language Focus 01. at present目前；现在= now / currently 例：At present, we can only travel to the moon for a short time. 02. take around 6-9 months花费约6到9个月的时间 例：The journey to Mars will take around six to nine months by spaceship. 03. during this period在此期间；在这一阶段 例：What will you do to keep healthy during this long journey? 04. hundreds of thousands of数十万的；成千上万的(近义: thousands / millions of) 例：It might take hundreds of thousands of years to build such a city. 05. not a completely wild dream并非完全的空想/天方夜谭= not impossible 例：Living on another planet is not a completely wild dream today. 06. cooperate with one another相互合作；彼此协作= work together 例：All countries should cooperate with one another to fight climate change. 07. there is hope that...有希望……；有望实现…… 例：There is hope that we will find a solution to the environmental problem. 08. set foot on登上；涉足；踏上（某地）= visit / arrive at a place 例：Humans first set foot on the moon in July 1969. Language Focus 01. It seems likely that... (似乎有可能……) 例：It seems likely that one day we will reach the distant stars. 拓展：同义替换 → It is possible that... / It is likely that... 02. One idea is to... Another is to... (一个是…另一个是…) 例：One idea is to sleep during the journey. Another is to develop faster spacecraft. 解析：用于并列列举方案，结构工整，强调对比或补充。 03. While this is not possible right now...
