M：Are you just going to stand there and let me do all the digging
W：In a minute, Ming.I am just appreciating these pictures on the wall.
M：What's so interesting about those pictures Just some boring daily lives people had in the Tang Dynasty.
W：You don't sound like a historian, Ming.The pictures are touching and ...
M：Oh, my ... Come here, Claire! Look what I've found!
W：Is it ... a bottle ①Oh, it's a mask.But it doesn't look like something that belongs to the Tang Dynasty.
M：②It doesn't.I've seen something like this from a book. It's a typical item made in the Song Dynasty.
W：A Song Dynasty's mask was found in a Tang Dynasty's tomb ③That's so strange. How is that even possible
M：③You got me.I think we need to discuss it with other professors.

W：How do you know how old a star is
M：For most stars, we find its age from how big it is. We can know its size from the amount of light it puts out, and its color. Then the size tells us how long a star will live. Big stars live a short life while small stars live much longer.
W：I've always wondered if there is an end in space. Do you think scientists have found the answer
M：This is a difficult question. The truth is that we have no idea! We currently don't have a way of testing it. But some scientists will come up with a way in the future. I have faith in it.
W：The last question is from our readers: do you believe there's other life in different parts of the universe
M：There are so many planets in the universe. Life may exist on other planets. But will we ever find or research them I think that's very unlikely.

Researchers in China have shown an ancient skull to the world for the first time. The skull could belong to a completely new species of humans that lived in Asia over 146,000 years ago. It could be from a group of humans that are the closest relatives to us. The researchers have nicknamed the person the skull came from “Dragon Man”. It was originally found by a Chinese worker in the city of Harbin in 1933 but was kept hidden at the bottom of his family's well. It stayed there for nearly 90 years. The man recently told his family about the skull before he died. His family located it and gave it to scientists.
Scientists say Dragon Man could greatly change our understanding of human evolution. They say he looked more like today's humans than any other members of the human family tree. The species Dragon Man belonged to is probably closer to modern-day humans than Neanderthals were. Researcher Chris Stringer of the Natural History Museum in London described Dragon Man's group. He said, “From the winter temperatures in Harbin today, it looks like they were coping with even harsher cold than the Neanderthals.”

阅读下面短文，根据短文内容，回答文后的问题。
How many things can you see in the night sky A lot! On a clear night you might see the Moon, some planets, and thousands of sparkling stars.
You can see even more with a telescope. You might see stars where you only saw dark space before. You might see that many stars look larger than others. You might see that some stars that look white are really red or blue. With bigger and bigger telescopes you can see more and more objects in the sky. And you can see those objects in more and more detail.
But scientists believe there are some things in the sky that we will never see. We won't see them with the biggest telescope in the world, on the clearest night of the year.
That's because they're invisible.They're the mysterious dead stars called black holes.
You might find it hard to imagine that stars die. After all, our Sun is a star. Year after year we see it up in the sky, burning brightly, giving us heat and light. The Sun certainly doesn't seem to be getting old or weak. But stars do burn out and die after billions of years.
As a star's gases burn, they give off light and heat. But when the gas runs out, the star stops burning and begins to die.
As the star cools, the outer layers of the star pull in toward the center. The star squashes into a smaller and smaller ball. If the star is very small, it ends up as a cold, dark ball called a black dwarf. If the star is very big, it keeps squashing inward until it's packed together tighter than anything in the universe.
Imagine if the Earth were crushed until it was the size of a tiny marble. That's how tightly this dead star, a black hole, is packed. What pulls the star in towards its center with such power It's the same force that pulls you down when you jump — the force called gravity. A black hole is so tightly packed that its gravity sucks in everything — even light. The light from a black hole can never come back to your eyes. That's why you see nothing but blackness.
So the next time you stare up at the night sky, remember: there's more in the sky than meets the eyes! Scattered in the silent darkness are black holes — the great mystery of space.
Questions：
1．What happens after a star dies
It becomes invisible.
2．According to the article, what causes a star to die
When its gas runs out, the star stops burning and begins to die.
3．What do paragraph 6 and paragraph 7 mainly talk about
The formation of black holes.
4．Why can't you see light when you look at a black hole
Because the gravity of a black hole is so strong that it sucks the light inward.3 / 3
