A black hole is created when a large star burns out. Like our sun, stars are unbelievably hot furnaces(熔炉) that burn their own matter as fuel. When most of the fuel is used up, the star begins to die.

The death of a star is not a quiet event. First there is a huge explosion. As its outer layer is blasted off into space, the dying star shines as brightly as a billion suns.

After the explosion gravity pulls in what’s left of the star. As the outside of the star sinks toward the center, the star gets smaller and smaller. The material the star is made of becomes tightly packed together. A star is so dense that a teaspoon of matter from it weighs billion of pounds.

The more the star shrinks, the stronger the gravity inside it becomes. Soon the star is very tiny, and the gravity pulling it in is unbelievably strong. In fact, the gravity is so strong that it even pulls light into the star! Since all the light is pulled in, none can go out. The star becomes black when there is no light. Then a black hole is born!

That’s what we know about black holes. What we don’t know is this: What happens inside a black hole after the star has been squeezed into a tiny ball? Does it keep getting smaller and smaller forever? Such a possibility is hard to imagine.

But if the black hole doesn’t keep shrinking, what happens to it? Some scientists think black holes are like doorways to another world.They say that as the star disappears from our universe, it goes into another universe. In other words a black hole in our universe could turn into a “white hole” in a different universe. As the black hole swallows light, the white hole shines brightly — somewhere else. But where? A different place, perhaps, or a different time — many years in the past or future.

Could you travel through a black hole? Right now, no. Nothing we know of could go into a black hole without being crushed.So far the time being, black hole must remain a mystery.

Black holes are a mystery—but that hasn’t stopped scientists from dreaming about them. One scientist suggested that in the future we might make use of the power of black holes. They would supply all of Earth’s energy needs, with plenty to spare. Another scientist wondered if a black hole could some day be used to swallow earthly waste—a sort of huge waste disposal (处理) in the sky!

       A.there is no fuel left in it B.its outer layer goes into space first

A week ago, I had the great pleasure of reading an e-book, When Money Talks, Listen! By Rich Ezzo.It took only about an hour to read.

   When I first received a copy, I thought it was a Get Rich Quick type of publication.Nothing is wrong with Get Rich Quick, but my mind just doesn’t chase after dreams of wealth.I think that if God ever wants me to be rich, he knows where to find my purse.

   When I began reading When Money Talks, Listen!, I was overjoyed to find that Rich Ezzo isn’t money hungry either.He, too, is hungry far more important than money.

Since I love this e-book so much, why wait a week to write the review? Simple.I wanted to see if the effect it had on me was a keeper.After reading the last word of the e-book, I totally agreed with the subtitle which promised to forever change the way we thought about money.I had so many thoughts running around my mind that I had to install(安装) a stoplight to stop some while others made their way into the picture, then I yielded(让路) them as a few ones arrived in town.I had a mental traffic jam, which only goes to show how slow the traffic usually is

   It has been a week and the effect is the same.I truly do look at money differently and have even done a few things differently this week.This is an e-book you’ll want to read, I promise.I often recommend books to my daughter, and this is one that I didn’t just “suggest”---I left it open at the bottom of the computer and told each one, “Read it, you’ll love it.”

   I would never point someone in a direction I wouldn’t go myself.I urge you to visit the author’s website, Myster Money, and to download the e-book.You won’t regret it.

       A.strongly recommend an e-book.

     B.he was not sure whether he did well
