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? /ɡɒd/ n. 神 /mɪˈstɪəriəs/ adj. 神秘的；奇怪的 Humans have long been curious about the stars. 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! /ˈspeɪskrɑːft/ n. 宇宙飞船 以防万一 /bɔːd/ n. 板；牌子 /ˈbɪljən/ num. 十亿 /ˈtrɪljən/ num. 万亿；兆 /ˈvɔɪɪdʒə / 旅行者1号探测器 No spacecraft has travelled close to a star. 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! /kəʊˈɒpəreɪt/ v. 合作；协作 Long distance space travel is difficult for humans. 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. /kəʊˈɒpəreɪt/ v. 合作；协作 /ˈɡæləksi/ n. 星系 访问；踏上（某地） In the future, it may be possible to visit a star. 1c Read again and match each paragraph with its main idea. Paragraph 1 A. Long distance space travel is difficult for humans. Paragraph 2 B. Humans have long been curious about the stars. Paragraph 3 C. In the future, it may be possible to visit a star. Paragraph 4 D. No spacecraft has travelled close to a star. 1d Complete the mind map with the information from the text. You can use your own words. wondered truth 1977 record six to nine safety sleep develop /ɪˌmædʒɪˈneɪʃn/ n. 想象；想象力 /ˌekspekˈteɪʃn/ n. 期望；希望 1e 1.What did some ancient cultures think about the stars? Why? They thought stars were gods or important symbols, because they had no modern science to explain space. 2.What is carried on board by Voyager 1? Why? A golden record with sounds and pictures of Earth, to send messages to possible alien life. 3.What is the farthest trip that a human has travelled from Earth? Do you know any details about it? Astronauts travelled to the Moon, about 380,000 kilometres away from Earth. 4.What do you think about the future of space exploration? Space exploration will make great progress, and humans may travel to Mars or other stars one day. Discuss the questions. Find more information to support your answers.
