阅读下面短文，简略回答问题。
Will humans someday live and work on Mars? Many scientists think so. In fact, they are already working on plans to turn Mars into a new Earth.
Humans need three basic things to live: water to drink, air to breathe, and food to eat. Because of the shortage of those above, it is impossible to live on Mars right now.
Then how can we make Mars the right place for humans to live? The answer is to change the environment of the planet so that it is similar to Earth's.
On Mars, the temperature is about -60℃. So one of the main goals is to warm it up. One idea for warming Mars comes from a problem here on Earth — climate change. Most scientists agree that Earth is becoming warmer because of increased levels of greenhouse gases in our atmosphere (大气). We might create similar conditions on Mars by building factories that give off greenhouse gases. The gas will change the atmosphere on Mars. Rain will fall, and it may be possible to grow plants for food. There will be many difficulties in changing Mars. The program could take many centuries, and the cost will be high. We have some of the technology, such as the ability to create greenhouse gases, but not the money. Anyway, life on Mars is a real possibility for future people.
1. What are the three basic things humans need to live?
2. How can we warm up Mars according to the passage?
3. What may happen after the atmosphere on Mars changes?
4. What are the two main difficulties in changing Mars?
5. Do you think humans should try to make Mars a new place to live? Why or why not?

5. Do you think humans should try to make Mars a new place to live? Why or why not?
Yes, I think so. Because Earth has serious pollution and a large population, and Mars might be a good choice for the future. / No, I don't think so. Because it would take many centuries and cost too much money. We should spend more time protecting Earth instead.
