Scientists have also discovered many other galaxies in the universe. Their light has to travel for many years to reach us. So how large is the universe?Well, it is impossible to 8 .
Scientists have sent 9 to Mars to take photos. Some of their probes have even travelled beyond the solar system. However, no spacecraft has travelled far enough to 10 planets beyond our solar system.
When we see stars twinkling(闪耀) in the sky at night, we may think a lot. With so many stars in the universe, is there life out there in space?

情境二 王强分享了中国科学家的一项突破性研究。
阅读理解(A)
Recently, a great scientific discovery amazed the world. Chinese scientists have 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. Their discovery shows that by using lunar soil, 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. 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 when it reaches over 1,000℃. When it begins to melt, it produces water vapour(蒸气). They learnt that just 100g of lunar

between 51kg and 76kg of water. That’s enough to give drinking water to 50 people for one day!
In general, the research opens up new possibilities(可能性) for finding water on the moon. It’s important for future trips to the moon and also important to 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!

阅读下面短文,并用英语回答问题(请注意每小题的词数要求)。
On 8 April 2024, millions of Americans put on their special glasses to watch a total solar eclipse. A solar eclipse is when the moon passes between the sun and Earth. As the moon shortly covered the sun, cities went into darkness.
There are five stages in a total solar eclipse.

Partial eclipse begins: The moon can be seen over the sun’s disk(日轮). It looks like the moon has taken a bite out of the sun.
Total eclipse begins: The moon covers the
entire disk of the sun, and people are now within the moon’s umbra(本影).
Totality and maximum(最大极限的) eclipse: The moon completely covers the disk of the sun. Only the sun’s bright ring can be seen. This is the most amazing stage of a total solar eclipse. At this time, the sky goes dark, and temperatures can fall.

Total eclipse ends: The moon starts moving away, and the sun reappears. Those lucky enough to be in the moon’s umbra can see the sun shine like a bright diamond(钻石) ring.
Partial eclipse ends: The eclipse ends as the moon leaves the sun’s disk.
Although we can’t watch the view this time, a total solar eclipse may take place in China in 2035. If you love watching the sky, _________________________.
