9、 阅读下面短文,根据短文内容选择最佳答案。
Recently, a great scientific discovery amazed the world. Chinese scientists have already found a new method to produce water on the Moon, which could change how we think about living on the Moon in the future. They wrote about their discovery in a science magazine called The Innovation. 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, which makes it hard to find and use water there. 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 brought back by the Chang'e-5 spacecraft. 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 vapour (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, the 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!
(1)、Why does the writer mention the earlier research in Paragraph 2?A、To show that it was totally 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.(2)、What condition is needed for lunar soil to produce water vapor according to the passage?A、It needs to be mixed with ice from the Moon's poles. B、It needs to be brought back to Earth by a spacecraft. C、It needs to reach a temperature over 1,000℃ and melt. D、It needs to be stored in a special box for a few days.(3)、How much water may scientists get if they have 1,000g of lunar soil?A、5.1g to 7.6g. B、51g to 76g. C、510g to 760g. D、5.1kg to 7.6kg.(4)、What's the writer's attitude (态度) towards the dream of humans living on the Moon?A、Hopeful. B、Worried. C、Surprised. D、Doubtful. -
10、 阅读下面短文,从各题所给的A、B、C、D四个选项中选出最佳选项。
Mars is the fourth planet from the Sun and the second-smallest planet of the solar system. It is1 than the Earth with a diameter (直径) of 6,792 kilometres. If you stand on Mars and 2 the Sun, it will appear about half the size as we see it on the Earth. Mars is widely known as the 3 planet. Its red appearance is caused by the iron oxide (氧化铁) in the ground.
In many ways, Mars can be considered as the Earth's brother. On Mars' surface, we have discovered the 4 mountain in the solar system. It is named Olympus Mons, and it is more than twice as high as the highest mountain on the Earth. A 5 on Mars is also a little longer than a day on the Earth. It lasts about 24.6 hours. A year on Mars, however, or the time that takes for the red planet to6 the Sun, lasts about 687 Earth days. That is almost7 as long as a year on the Earth!
In the 19th century, it was believed that8 existed on Mars. An astronomer said that he "found" straight lines on Mars's surface. Many people believed that 9 were the work of smart life as the straight lines were most likely to be canals for irrigation (灌溉渠). However, as more advanced telescopes were 10 , it was found that the straight lines were an optical illusion (视觉假象).
To this day, humans are still trying to find out whether life exists on Mars.
