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 TAXI driver taught me a million dollar lesson in customer satisfaction and expectation. Inspiring speakers charge thousands of dollars to give his kind of training to corporate directors and staff.  It cost me only a ＄12 taxi ride.

I had flown into Dallas just for the purpose of calling on a client. Time was important and my plan included a quick turn – around trip from and back to the airport. A clean taxi pulled up.

As be got in the driver’s seat, he mentioned that the neatly folded Wall Street Journal next to me for my use. He then showed me several tapes and asked me what type of music I would enjoy.

As a professor at a large American university, there is a phrase that I hear often from students: “I’m only a 1050. ”The unlucky students are speaking of the score on the Scholastic Aptitude Test (SAT), which is used to determine whether they will be admitted to the college or university of their choice, or even have a chance to get a higher education at all.  The SAT score, whether it is 800, 1 100 or 1550, has becomes the focus at this time of their life.

It is obvious that if students value highly their test scores, then a great amount of their self-respect is put in the number.  Students who perform poorly on the exam are left feeling that it is all over. The low test score, they think, will make it impossible for them to get into a good college. And without a degree from a prestigious university, they fear that many of life’s doors will remain forever closed.

According to a study done in the 1990s, the SAT is only a reliable indicator of a student’s future performance in most cases.  Interestingly, it becomes much more accurate when it is set together with other indicators——like a student’s high school grades. Even if standardized tests like the SAT could show a student’s academic proficiency（学业水平）,they will never be able to test things like confidence, efforts and willpower, and are unable to give us the full picture of a student’s potentialities（潜力）. This is not to suggest that we should stop using SAT scores in our college admission process.  The SAT is an excellent test in many ways, and the score is still a useful means of testing students.  However, it should be only one of many methods used.

A. strong will                                  B. academic ability

A few years ago, when I was still in high school, I met a wonderful and warm teacher. At that time in my life, there were many changes to adjust to, apart from the usual teenage troubles. My parents had divorced, so my elder brother and I had chosen to stay with my dad. Due to the fact that he was keeping the house, we didn’t have to move.

During this time, my teacher took a special interest in me. Being my English teacher, she encouraged my mind to travel to creativity I had long given up. She brought me out of the shell I built.

She became my mother, my older sister, my friend and my teacher. The one thing she couldn’t do though was to make me more girly as growing up with only my dad and brother made me a real tomboy.

Sometimes, I would be really immature（不成熟的）, especially if she was scoring me less than others on purpose. She knew I could do better than what I was handing in and so pushed me to extend further than limits.

When I finished school and then after college I was about to leave my hometowns she gifted me a watch that every second, with my pulse, should remind me of the one person who will forever wait and love me without reservation.

Time has passed and our friendship is distant, but in my heart, soul and mind, she is the closest I ever got.
