题目列表(包括答案和解析)

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 the star begins to die ______.

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

C. a huge explosion will happen                         D. it doesn’t give off light any longer

Which of the following doesn’t help produce a black hole?

A. The gravity inside the star is very strong.        B. The light can’t go out of the star.

C. The star becomes smaller and smaller             D. The dying star shines very brightly.

The black hole ______.

A. continues becoming smaller and smaller all the time

B. goes into another universe and becomes a white hole

C. can pull in everything we know of in the world

D. will appear at another place at a different time

What’s the best title for this passage?

A. A New Scientific Discovery: Black Holes

B. How Do Black Holes Come Into Being?

C. What Are Black Holes?

D. Travel Through A Black Hole

From E-mail to online shopping, you may think you’ve heard everything there to know about the electronic frontier (新领域).But with hundreds of thousands of Web pages being added weekly, there are plenty of surprises out there.Here are some of the most intriguing (有迷惑力的).

……

Put your kid on a greeting card.Here is how: simply take some pictures with a regular camera, and then ask the photo service to develop them digitally (数字化).For a small fee, you’ll receive your photos on a desk.Put that into your computer and, with a few clicks of the mouse, you can view your photos on the screen.With a few more keystrokes, you can attach the photos to email and send them to friends and relatives worldwide.

  Sign on to one or several greeting card’s Websites (http://www.cardcentral.net/ is an index of more than 1200 electronic card sites) and create an electronic birthday or holiday card.Using your digital photos, you can paste your grandchildren onto the cover.

  If you don’t want to use your own photos, go to cards.amzon.com to browse (浏览) hundreds of images in over 30 categories…all of which you can attach to an electronic greeting card for free.For a nominal fee(很低的费用)you can choose from a library of 75,000 images at http://www.phontodisc.com/.

  Call Australia for free.To have a telephone conversation over the Internet, the person you want to talk to no longer needs a computer.Now all you need to talk to someone in Sydney is one computer with speakers, a microphone, a sound card and some software (available at http://www.vocaltec.com/ or Mricrosoft.com).Typically, you’ll pay a monthly fee (usually under $20) to a service provider, but after that, the calls themselves are local.Sound quality is the same as that of a cell phone.

  Even if you don’t have a computer, you can still use the Web to reduce your long distance phone costs.Some companies offer a service that lets you use an ordinary phone to call another ordinary phone, but charge only a few cents per minute for US calls, because they send them through the Internet.

  Today 48 percent of American homes have computers…a figure that is expected to climb to 60 percent by 2003.And by the end of the next decade, Americans will likely be spending more time shopping, banking, investing and learning on the Internet than in the real world.If you can’t do or find something on the Net today, you probably can tomorrow.

60.Over the Internet, you ________.

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.

Well! I looked around for a “Candid Camera!” Wouldn’t you? I could not believe the service I was receiving! I took the opportunity to say, “Obviously you take great pride in you work. You must have a story to tell.”

“You bet,” he replied, “I used to be in Corporate America. But I got tired of thinking my best would never be good enough. I decided to find my right position in life, somewhere I could feel proud of being the best I could be.

I knew I would never be a rocket scientist, but I love driving cars, being of service and feeling like I have done a full day’s work and done it well. I evaluated my personal property and, I became a taxi driver!

One thing I know for sure, to be good in my business I jus have to meet the expectations of my passengers. But, to be GREAT in my business, I have to EXEED the customer’s expectations! I like the sound of being ‘great’ better than just being ‘average’. ”

Did I tip him big time? You bet!
