We may _______ ______________________________. us better understand Earth's geology, history, and relationship with other planets benefit us here on Earth find new resources in outer space 10 What does the study of other planets help us understand about Earth? It helps us understand Earth's geology / history / relationship. 2. What example is given for the benefits of space technology? What problem does it help with? Satellites. They help us deal with problems caused by climate change. 3. Why might we need a new home in the future? Earth may run out of resources. 11 Improve our knowledge of Earth and its place in the universe ● Earth’s formation: Studying the moon, Mars, and other planets helps scientists learn how Earth formed, how it has changed over time, and why it can support life. ● Ancient history: Other planets and the moon preserve (保存) old surfaces better than Earth, so they provide clues (线索) about the early history of the solar system. For example, the moon still shows impact (影响) marks from billions of years ago. 12 Technology developed for space can benefit us ● Weather forecasting: Satellites help track storms, droughts, and climate change. ● Communication: Space technology supports TV, phone, and internet signals. ● Medical technology: Space research has led to better medical tools and equipment. Find new resources in outer space ● Scientists search the moon, Mars, and asteroids (小行星) for useful resources such as water ice, metals, and helium-3. ● Water ice on the moon could help provide drinking water, oxygen, and rocket fuel. ● Mars may contain water and minerals that could support human life and future space missions. 13 Host: Our question today is: Why do we explore space? Let’s talk to space scientist Dr Yang. Welcome, Dr Yang! Dr Yang: Thank you very much. Well, there are three good reasons to explore space. First, to improve our knowledge of Earth and its place in the universe. Host: Could you explain that a bit more? Dr Yang: Sure. The study of other planets helps us better understand Earth’s geology, history, and relationship with other planets. Host: Oh, right. Dr Yang: Second, technology developed for space can benefit us here on Earth. Host: Could you give our listeners an example? Dr Yang: Of course. Some satellites, for example, help us deal with problems caused by climate change. Host: Yes, that’s very useful. And the third reason? Dr Yang: Well, at some point in the far future, we may find new resources in outer space. It might sound crazy, but our Earth may run out of resources. In that case, a new home for us human beings will be needed. Host: Wow, interesting! Maybe Mars will be turned into our new home in the future. Function: Ask for clarification Function: Ask for an example Function: Make comments / responses Function: Move to next point What are the functions of these sentences? 14 Host: Our question today is: Why do we explore space?

First,… Second,… Third,… 18 Why do we explore space? To understand ourselves and the universe Exploring space helps us learn more about the universe and our place in it. It helps answer some basic questions such as: Why are we here? How did it all begin? Are we alone? What comes next? How can we make our lives better? 19 To protect Earth No matter how much social or environmental progress we make, everything could still be at risk if Earth were struck by a large asteroid. By exploring space, we can find, track, and study asteroids and comets near our planet. This helps us protect Earth and prepare for possible dangers in the future. To inspire people Space exploration inspires people, especially young students, to dream big and develop skills in science, engineering, medicine, and many other fields. To encourage international cooperation Space projects often bring different countries together. By working together, nations can share knowledge, build trust, and promote peaceful cooperation. 20 Work with a partner to discuss your reasons for space exploration. A: Why do you think people want to explore space? B: I think there are several reasons. First, scientists might discover new planets and stars. A: Oh, right. It also helps us learn more about the universe. B: Second, exploring space inspires young people to study science and technology. 21 A: That's true. Many students become interested in science because of space. B: Third, space missions might find other life in the universe! A: Maybe they will. I think space missions can help countries work together too. B: Wow, interesting! I like that idea. 22 Host: Our question today is: Why do we explore space? Let’s talk to space scientist Dr Yang.
