Choose the ones that are true for you. A. Popular science magazines. B. Science fiction books. C. Online news. 1b Read the title and the text quickly. Where would you find an article like this? Identifying the text type Before you read, decide what kind of text it is. Is it a sci-fi story, popular science article, news report, or something else? 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 technology and science 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-closet star, Proxima Centauri. That star is 4.2 light years away—about 40 trillion kilometres! 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. On a popular science magazine.（仅供参考） 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. Can we visit the stars one day?
