Unit 5 Off to space Section 1 Experiencing and understanding language Reading Page 69 Read Li Jun's diary entry and think about what a trip to the Moon would be like. 1 October 2053. Flying to the Moon I'm so happy! Tomorrow I'll be one of the first students to travel into space. The spaceship will leave the Earth at 9:00 a.m. It'll take us to the Moon. I can't wait! The Moon is around 380,000 kilometers from the Earth, so it'll take us about three days to get there. The gravity in space is very weak, so we'll all be floating around in the spaceship. And we won't sleep in beds—we'll sleep in sleeping bags. We need to tie the sleeping bag to the wall so that we won't float away in our sleep! Because of the low gravity, our bodies may get weak, so we'll have to do exercise every day. When we arrive, I'm going to walk on the Moon. The Moon has much weaker gravity than the Earth. A person weighs much less on the Moon, so we can jump very high. I'll have to wear a spacesuit to help me breathe because there's no air on the Moon. That also means there is no sound there. We can only hear the sounds inside our spacesuits. The Moon is a strange and mysterious place. I'm going to take as many photos as I can. I'm sure that it'll be a wonderful trip! 飞往月球 我太兴奋了！明天我将成为首批学生中的一员，乘坐宇宙飞船前往太空。飞船将于上午9:00离开地球，目的地是月球。我迫不及待了！月球距离地球大约380,000公里，我们抵达那里大约需要三天的时间。太空中的重力非常微弱，所以我们在飞船内都会漂浮起来。我们不会睡在床上，而是睡在固定在墙上的睡袋里，以防止在睡眠中飘走。由于太空中的微重力，我们的身体可能会变得虚弱，因此我们每天都需要做锻炼来维持肌肉力量。 当我们到达月球时，我打算在月球上行走。月球的重力远远小于地球，因此在月球上我们的体重会很轻，可以跳得非常高。我需要穿着宇航服来帮助呼吸，因为月球上没有空气。这也意味着月球上没有声音，我们只能听到宇航服内的声音。 月球是一个充满神秘的地方。我计划尽可能多地拍摄照片。我确信这将是一次美妙的旅行！

Section 3 Expressing and communicating ideas Speaking. Talking about plans for a trip to space Page 75 Imagine that you are going to go on a trip to space. Talk in pairs about your plan for the trip. S1：Life in space is quite different from life on Earth. What will you prepare for your trip? S2: I will pack ... S1: What are you going to do when you are in the spaceship? S2: I'm going to. S1: Where will you travel, and what will you do there?

Section 4 Extending and developing competencies Focusing on cultures Page 78 Among all the planets in the solar system, Mars is the one that humans have been most curious about. Let's learn about Tianwen-1 and find out more about Mars exploration. 1. Read the article and find out how Chinese people have studied Mars. Exploring Mars On 23 July 2020, China's first Mars lander, Tianwen-1, was sent into space from Wenchang, Hainan Island. The spacecraft takes its name from an ancient poem by Qu Yuan (340-278 BCE). “Questions to Heaven” and expresses China's determination to explore the universe. Mars has interested people for thousands of years. Around 3,000 years ago in ancient China, people already knew about the planet and began to study how it moved in the sky. However, it was difficult to find out more about it before the 20th century. Thanks to the work of scientists, we have learnt a lot about Mars. Spacecraft like Tianwen-1 will help us find out more about our red neighbor. After travelling more than 470 million kilometres, Tianwen-1 reached the red planet on 10 February 2021. The craft circled around the planet for three months before landing on the surface on 15 May. There, it released a 240-kilogram rover named Zhurong. During the next 100 days, Zhurong drove 1,000 metres on the planet's surface and continued its travel.It took photos of Mars and studied different kinds of rocks. and then it sent the information back to the Earth. The success of Tianwen-1 is only the beginning of China's Mars exploration programme. Maybe one day Chinese astronauts will visit Mars.探索火星 2020年7月23日，中国首个火星着陆器“天问一号”从海南岛文昌发射升空。该航天器的名字取自屈原（公元前340年—公元前278年）的一首古诗。 “天问”意为“向天发问”，表达了中国探索宇宙的决心。 几千年来，火星一直吸引着人们的关注。大约在3000年前的中国古代，人们就已经知晓这颗行星，并开始研究它在天空中的运行规律。然而，在20世纪之前，人们很难进一步了解它。多亏了科学家们的努力，我们对火星已经有了很多认识。像“天问一号”这样的航天器将帮助我们进一步了解我们这颗红色的近邻。 经过4.7亿多公里的飞行， “天问一号”于2021年2月10日抵达这颗红色行星。在5月15日着陆火星表面之前，该航天器环绕火星飞行了三个月。在火星上，它释放了一辆重240千克、名为“祝融”的火星车。 在接下来的100天里， “祝融”号在火星表面行驶了1000米并继续前行。它拍摄了火星的照片，研究了不同种类的岩石，然后将相关信息传回地球。 “天问一号”的成功仅仅是中国火星探测计划的开端。也许有一天，中国宇航员将会造访火星。

Cross-curricular connection: Space science Page 80 For thousands of years, human beings dreamt of exploring the night sky. It took a lot of hard work to make this dream come true. 1.Read about different firsts in space below. Match the years and headings (1-6) with the paragraphs (a-f). Famous firsts in space. (1) 1957 the first satellite (2) 1961 the first manned space flight (3) 1965 the first spacewalk (4)1969 the first manned Moon landing (5) 1971 the first space station (6) 2019 the first unmanned spacecraft on the Moon's far side A. The Soviet Union sent the space station Salyut 1 into orbit. Later that year, three Soviet astronauts visited the space station. They spent 23 days there. B. The Chinese spacecraft Chang'e-4 landed on the far side of the Moon. The spacecraft brought with it the second Chinese lunar rover Yutu-2. C. The American astronauts Neil Armstrong and Buzz Aldrin landed on the Moon. They collected rocks and brought them back to the Earth. D. The Soviet astronaut Yuri Gagarin flew into space on the spacecraft Vostok 1. He travelled around the Earth once. The whole flight lasted 108 minutes. E. The Soviet astronaut Alexei Leonov went on a 12-minute spacewalk. F. The Soviet Union sent the satellite Sputnik 1 into space. It stayed in orbit for three months.
