Summarize the reasons for space exploration mentioned in the article. Reasons for space exploration 1 2 3 4 5 It is in our nature to satisfy humans’ curiosity. It enables us to learn more about the origin, evolution , and likely future of the universe.

Discussion 1. The article talks about the advantages and disadvantages of space exploration. Do you agree or disagree with the author’s opinion? Why? s,write novels, translate foreign languages and do many other things. From this point of view, AI can be friends with humans. Discussion 1. The article talks about the advantages and disadvantages of space exploration. Do you agree or disagree with the author’s opinion? Why? Possible answer I agree with the author’s opinion. One of the key advantages mentioned in the article is that the exploration of space has brought us technologies that we use in our everyday lives. For example, the small cameras that we find on our mobile devices were first developed so that they could be used on the spacecraft. Another important advantage the author mentions is that space exploration inspires young people to study hard and build careers in science and engineering. These fields are absolutely crucial for the future of humanity, and space exploration plays a vital part in this. Discussion Possible answer I do not agree with the author’s opinion because I believe that the focus should be on developing technology to keep the Earth and all its inhabitants safe and healthy. This planet is our home. Whether or not we might one day travel to and live on another planet, I am sure the technology and knowledge we have today would still exist. Besides, I think that preventing climate change is more important than hurrying to make advances in technology that are not necessary for living well on the Earth. Discussion 2. Our exploration of space has already taught us many things. What do you the future of space exploration holds for human understanding? Give reasons for your opinion and support your reasons with evidence. Possible answer The future of space exploration will expand our understanding of our role as humans. As space exploration reveals more mysteries, our perspective of our planet and ourselves will change. Past space exploration raised awareness of the need for global solutions to challenges. Furthermore, space exploration requires global cooperation, which is already practised on the International Space Station. Hopefully, future knowledge will help us understand the importance of working together to solve other problems on the Earth, such as poverty, hunger and war. 04. Project Project As a class, discuss the seven planets and the Moon in the solar system, where humans could possibly move to live.Then in groups,choose one to research. Mercury Jupiter Uranus Mars Venus Saturn Neptune Moon Project As the closest planet to the Sun , Mercury is also the smallest planet in the solar system. Its surface is rocky and covered with craters(火山口). Without an atmosphere, it has no liquid water and suffers from extreme temperature swings—dropping to -173°C at night and rising to 427°C during the day. Mercury (水星) Project Similar in size to Earth, Venus is about 108.2 million kilometers from the Sun. It has a thick, toxic(有毒的) atmosphere mostly made of carbon dioxide, which makes its surface temperature reach up to 462°C and atmospheric pressure 92 times that of Earth. There is no liquid water on Venus, and acid rain(酸雨) is common. Venus (金星) Project Mars is about 227.9 million kilometers from the Sun, known for its red, rocky surface with volcanoes. It has a thin atmosphere mostly composed of carbon dioxide, with an average temperature of -63°C. While there is no liquid water, small amounts of frozen water exist on the planet. Mars (火星) Project Jupiter is the largest planet in the solar system. As a gas giant, it has no solid surface(固体表面). Its thick atmosphere is filled with storms (such as the Great Red Spot), and it has strong gravity (2.5 times that of Earth) along with extreme pressure and temperature. Jupiter (木星) Project As another gas giant, Saturn is famous for its beautiful rings made of ice and rock. It has no solid surface, a thick atmosphere, strong gravity (1.1 times that of Earth), and an average temperature of -140°C. Saturn (土星) Project Uranus is classified as an ice giant. It has a thin atmosphere, an extremely cold average temperature of -195°C, and no solid surface. Strong winds are also a feature of this planet. Uranus (天王星) Project The farthest planet from the Sun, Neptune is an ice giant with a thick atmosphere and supersonic(超音速的) winds. It has an extremely cold average temperature of -200°C, no solid surface, and is dark most of the time. Neptune (海王星) Project The Moon is Earth’s natural satellite, smaller in size than Earth. Its surface is dry, rocky, and covered with craters. Without an atmosphere to protect it, there is no liquid water on the Moon, and it experiences extreme temperature changes, ranging from -173°C to 127°C. Moon Project As a group, research your chosen heavenly body and brainstorm the challenges it will present. Try to think of solutions to the challenges. Use the ideas below to help you. Basic information (size,distance from the Sun/Earth, surface features, climate, water, atmosphere, etc.) Challenges(resources, food supply, cold, radiation, communication with the ground, etc.) Solutions Project Make a a profile Read the sample in Part C on Page 27 to learn how to make a profile on how to live beyond the Earth. and answer the following questions. 1. What does the sample mainly focus on? 2. What are the challenges people have to overcome on Mars? 3. What solution does the sample give? 4. What do you think of the sample? Project Project 1.What does the sample mainly focus on? 2. What are the challenges people have to overcome on Mars? 3. What solution does the sample give? It mainly focuses on how to live on Mars. Radiation and dust storms. We should find permanent shelter that offers long-term protection,such as building a special structure near Mars’ freezing north pole.We could also take advantage of the solar energy or construct nuclear power stations to satisfy your energy needs.

In the future, Mars will be a good place for people to live in, because people will produce enough air and water on Mars. What life will be like on Mars in the future? Just like they’re on the earth, people will be busy with working and studying on week-days. At weekends, they will relax by going to the park. During a long holiday, they’ll return to the earth by spaceship to visit their families and friends. Life on Mars will be very interesting. Homework With the increasing population on Earth, human beings have been trying to find another planet in space to live on. It is reported that liquid water has been found on Mars, which provides necessary conditions for all living things. To some extent, the climate on Mars is quite similar to that on Earth, which makes it possible for humans to live on Mars. Therefore, it is quite probable that humans will live on Mars one day. As far as I am concerned, I would be willing to live on Mars if I got the chance in the future. Since it is a completely new place, I think it will be magical.
