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 shining stars.

You can see even more with the help of new inventions. You might see stars where before you only saw dark space. 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. You can find out more about those objects.

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 can't be seen. They're the mysterious(神秘的)dead stars called black holes.

You might find it hard to imagine that stars die. But stars do burn out and die after billions of years.

As a star burns, it gives off light and heat. But when the star burns out, it begins to die.

As the star cools, the outer parts of the star pull in toward the center. The star squashes into a smaller and smaller ball. If the star was very small, the star ends up as a cold, dark ball called a black dwarf(黑矮星). If the star was very big, it keeps squashing inward until it's packed together tighter(紧的)than anything in the universe.

Imagine if the Earth were squashed until it was the size of a tiny ball. That's how tightly this dead star, a black hole, is packed. What pulls the star in toward its center with such power? It's the same force(力量)that pulls you down when you jump—the force called gravity(重力). A black hole is so tightly packed that its gravity sucks(吸收)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 look up into the night sky, remember: there's more in the sky! All over in the darkness are black holes—the great mystery of space.

1.From the passage we know a black hole is .

A. a huge hole in the universe

B. a group of stars packed together

C. a dead star that is packed tightly

D. complete silent darkness in space

2.When a star squashes it will .

A. turn into a ball B. suck in everything

C. get smaller and smaller D. become darker and darker

3.The passage is mainly about .

A. how stars burn out

B. what dead stars are

C. how we can see more stars

D. why stars give heat and light

When you work long hours and Sundays are no longer a day to rest, feeling overworked can become the new normal. Take sportsmen as examples and do the same yourself, so you’ll know if you’re overworking.

Check your resting heart rate (率). Every day, before you get out of bed, take your pulse (脉搏). Usually your heart rate will stay within a few beats every minute. But when you’re overworked, the rate increases. If your heart rate is up in the morning, get a little more rest or sleep that night.

Check your emotions. Getting angry easily? If you can’t put your finger on a clear reason, there may be something wrong with your emotions. Hoping to change the condition won’t help. The only way out is a break.

Check your weight. If you lose or increase more than 1% of body weight from one day to the next, something is wrong. Maybe yesterday you were too busy and failed to notice you didn’t eat and drink enough. Or maybe you failed to notice that you were eating too much.

1.How many ways are mentioned to check if we’re overworking?

A. Two. B. Three.

C. Four. D. Five.

2.When should we check our heart rate?

A. In the morning. B. In the afternoon.

C. At noon. D. At night.

3.What is the best way to deal with the problem of overwork?

A. Doing more sports.B. Drinking more water.

C. Having more rest.D. Eating less food.

Hershey chocolate has become famous around the world. But did you know that the Hershey chocolate factory is only about one hundred years old? And did you know that the founder(创办人)of Hershey Chocolate, Milton Hershey, had many failures (失败)in business before he started his famous company?

Milton Hershey grew up in a farm country of Pennsylvania. Before he started making chocolate, Milton Hershey was a printer. He worked for a small newspaper and then he decided to change a job.

Later he got a job at a candy factory. After working a few years at the factory, he decided to open his own little candy business, His first business had to close down because it was not making money. After that, he traveled to Denver, Colorado, to learn how to make caramels(焦糖).

He took his new skills back to New York and worked selling candies on the street. But this second business also failed.

Finally, Milton Hershey moved back to the farm country where he grew up. He then experimented(试验)with all sorts of different candies and chocolates. The area where he lived had lots of dairy farms, so he could get plenty of fresh milk easily.

And he could get other supplies(原料), such as sugar, from nearby Philadelphia. By 1893 he was selling a million dollars worth of caramel candy every year. Since his chocolate-flavored(巧克力风味)caramel was the best-selling, he decided to make chocolate himself.

By experimenting, Milton Hershey learned how to make delicious chocolate by using fresh, sweet milk. His milk chocolates were so popular that he sold his caramel factory and made chocolate only. In 1903, Milton Hershey built a huge chocolate factory and the town of Hershey.
