Recently, a great scientific discovery amazed the world. Chinese scientists have already found a new method to produce water on the Moon. It could change how we think about living on the Moon in the future! Their discovery shows that by using lunar soil（月壤）, scientists can create a lot of water on the Moon.
In the past, missions to the Moon showed that there might be ice at the Moon’s north and south poles（极）. However, there isn’t much water in lunar soil—only a little bit, like 0.0001 percent to 0.02 percent. So it’s difficult for people to expect to live on the Moon.
The researchers, however, found something exciting, after studying the rocks and soil from the Moon. They were brought back by the Chang'e-5 spacecraft. One of the exciting things they discovered is that lunar soil melts when it reaches over 1,000℃. When it begins to melt, it produces water vapor（蒸气）. They learned that just 100g of lunar soil can give us 5.1g to 7.6g of water. So, if we had one ton of lunar soil, we could get between 51kg and 76kg of water. That’s enough to give drinking water to 50 people for one day!
All in all, this research opens up new possibilities for finding water on the Moon. It’s important for future trips to the Moon and people who might live there someday. As we learn more about how to make water from lunar soil, we get closer to the dream of humans living on the Moon. This discovery could help make that dream come true!
19. (
A. To show that it was completely wrong.
B. To compare it with the new discovery.
C. To prove that there is no running water on the Moon.
D. To explain why people wanted to live on the Moon before.

A. Hopeful. B. Worried.
C. Surprised. D. Doubtful.
