Ⅲ. 阅读下面语篇，从每小题所给的A、B、C三个选项中，选出一个最佳选项。
Why Do We Explore Space?
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. For example, by studying Mars’ climate and surface, we can learn more about how Earth’s environment changes over time.
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. They can monitor global temperatures, track natural disasters, and provide data for weather forecasting. Space technology has also led to improvements in medical imaging, GPS, and many other daily tools.
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.
