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!

When 47-year-old volunteer Susan Boyle stepped onto the stage of Britain’s Got Talent and announced she was unemployed, had never been married and “never been kissed, actually”, few in the audience would have wondered why. This Ms Boyle, looking unfashionable, from a village in Scotland, shocked the three judges and the audience with the song I dreamed a dream from the musical Les Miserables on a show of Britain’s Got Talent, one of the hottest reality shows in Britain.

She couldn’t hide the awkwardness when walking to the center of the stage in a housedress, and everyone — including the judges — seemed laughing at her when she said she wanted to be as successful as Elaine Paige. As soon as she began singing, however, everyone in the auditorium fell silent, then rose within seconds to applaud her incredible voice as the celebrity judges sat open-mouthed, and remained standing to the end.

After her performance, one of the judges Piers Morgan said, “Without doubt that was the biggest surprise I’ve had in three years of this show. When you stood there everyone was laughing at you. No one is laughing now. That was amazing.” Actress Amanda Holden followed, “I’m so thrilled because I know that we everybody were against you. I honestly think that we were all being very cynical (愤世嫉俗的) and I think that’s the biggest wake up call ever.”

Susan obviously won over the hearts of millions around the world with sensation spreading across the Atlantic. Hollywood actors Ashton Kutcher and Demi Moore — who between them have nearly 1.5 million followers — speak highly of her. Kutcher posted a link to the video clip (片段). The Scottish talent made her live American debut via satellite connection on CBS’s The Early Show, doing an interview and singing live from her room. And she already accepted an invitation from talk show host Oprah Winfrey.

Now Boyle has become one of the world’s hottest celebrities. The video clip of her performance has been viewed more than 50 million times on Youtube, becoming a hit on the Internet.

When I was a child, I often dreamed of the time when I could leave home and escape to the city. We lived on a farm. In the winter especially, we were quite far away from the outside world. As soon as I left school, I packed my bags and moved to the capital. However, I soon discovered that my life has its problems too.

One big disadvantage is money. It costs so much to go out, not to mention basics like food and housing. Another disadvantage is pollution. I suffer from asthma (哮喘), and the air is so serious polluted that I am afraid to go outside. Then there is the problem of traveling round. Although I have a car, I seldom use it because of the traffic jams. One choice is to go by bicycle, but that can be quite dangerous.

Of course there are advantages. First, there is so much to do in the city, whatever your tastes in culture or entertainment (娱乐活动). Besides, there are wonderful jobs and greater chances of moving to a more important job or position. Finally, if you like shopping, the variety of goods is very surprising — and , what is more, shops are often only a short walk away.

Is life better then, in the city? Perhaps it is, when you are in your teens (十几岁) or twenties. However, as you get older, and especially if you have small children, the peace of the countryside may seem preferable. I certainly hope to move back there soon.

What was the writer always thinking about when he was a child?

A. Staying on the farm.                      B. Leaving home for the city.

C. Moving to the countryside.             D. Running away from the school.

Which of the following is true about the writer?

A. He lives in the city now.           B. He is in good health.

C. He prefers driving a car.                D. He is very old now.  

In the passage, the writer tries to __________.

A. persuade the reader to live in the city         B. describe his life in the countryside

C. show an interest in the outside world           D. express his opinions about the way of life

How is the passage mainly developed?

A. By inferring.                B. By listing examples.       

C. By comparing.          D. By giving explanations.

 When I was 17，I read a quote that went something like：“If you live each day as if it were your last，someday you’11 most certainly be right．”It made a deep  36  on me．and since then。for the  past 33 years，I have  37  in the mirror every morning and asked myself：“If today were the last day of my life，  38  I want to do what I am about to do today?”And whenever the answer has been“No”for too many days in a  39  ，I know I need to change something．

    Remembering that I’ll be  40  soon is the most important tool I’ve ever known to help me make the big  41  in life because almost everything falls away in the face of death，  42 only what is truly important

    About a year ago I was  43  with cancer My doctor even advised me to go home and get my affairs  44  order，which is a doctor’s way of telling people to prepare to die．I  45  with that diagnosis all day．  46  ，at last an advanced test showed that i。。t was a very rare cancer that is  47  with surgery．I had the surgery and I’m fine now

     48  wants to die．Even people who want to go to heaven don’t want to die to get there And yet death is the destination we all  49  ．No one has ever escaped it. And that is as it should be，because death is very likely the single best invention of  50  ．It is life's change agent It clears out the old to  51  for the new．Right now the new is you．but someday not too  52  from n6w，you will．gradually’become the old and be cleared away．Sorry to be so dramatic，but it is quite true．

    Your time is  53  ，so don’t waste it living，someone else’s 1ife．Don’t be  54  by dogma（教条） —which is living with the results of other people’s thinking．Don’t let the noise of others’opinions drown out your own inner  55  ．And most importantly，have the courage to follow your heart
