China launched Chang'e 5 comprising an orbiter, a lander, ascender and a returner, and successfully landed on the near side of the moon and sent back images on Dec 1, 2020.
1. China’s other achievements:
The exploration of the moon (China's Chang'e Program)
2. What other major breakthroughs in space exploration do you know about?
I know about the first image of a black hole that was released in April 2019. In 2017 a network of linked radio telescopes around the world made observations of a distant galaxy that contained a massive black hole at its centre. No human had ever seen an actual picture of a black hole before, so these observations resulted in this historic image. It was the first time that we had been able to determine what a black hole might look like and the discovery also revealed more support for Albert Einstein’s general theory of relativity.

Read the passage quickly and get the main idea of the text.
Living in space is every would-be astronaut's dream. My six-month stay on a space station has come to an end, and it has been a challenging but magical adventure. I bet you'd love to know what daily life is like up in space and how it differs from that on the Earth—the low gravity definitely makes ordinary things strange!
During our leisure time, there's nothing we like more than to sit back with the rest of the crew and watch our remarkable planet go by, taking pictures for our family and friends back home. As the space station travels at a speed of about 17,500 miles per hour, we get to see the sunrise every 90 minutes. In these precious moments, all the challenges of life in space seem worth it.

What do spacesuits allow astronauts to do?
Spacesuits allow them to breathe in space and protect them from exposure to the cold and radiation.
Para. 4
How do astronauts eat and drink water or any other liquids?
They eat dried or freeze-dried food. They drink water or any other liquids out of a bag through a thin tube of plastic.
Para. 5
