四、阅读理解，本大题共5小题，每小题3分，共15分。阅读下列短文，根据短文内容选择最佳选项。

①Recently, a great scientific discovery surprised the world. Chinese scientists found a new method to produce water on the Moon. It could change how we think about living on the Moon in the future!

②In the past, missions to the Moon showed that there might be ice at the Moon’s north and south poles （极地）. However, there isn’t much water in lunar soil—only a little, like 0. 0001 percent to 0.02 percent. This makes it hard to find and use water there. So it’s difficult for people to expect to live on the Moon.

③The researchers, however, found something exciting after studying the rocks and soil from the Moon brought back by the Chang’e-5 spacecraft （嫦娥五号月球探测器）. One of the exciting things they discovered is that lunar soil melts （融化） when it reaches over 1,000℃. When it begins to melt, it produces water vapor （蒸汽）. 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!

④All 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 one day. 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!

26.What is the discovery about?

A．Ice at the Moon’s north and south poles.

B．A new way to travel to the Moon safely.

C．A new method to produce water on the Moon.

D．Rocks and soil are building materials on the Moon.

27.Why does the writer speak of the earlier research in Paragraph 2?

A．To show that the earlier research was wrong.

B．To compare it with the new scientific discovery.

C．To prove that there is no running water on the Moon.

D．To find out why people wanted to live on the Moon before.

28.How much water may scientists get if they have 1,000g of lunar soil?

A． B． 

C． D．

29.What’s the writer’s attitude towards the dream of living on the Moon?

A．Positive. B．Worried. C．Surprised. D．Unclear.

30.The passage is trying to tell us that ________.

A．humans are the builders of the moon. 

B．mistakes often help scientists find the truth.
