B

When I asked my daughter which item she would keep; the phone, the car, the cooker, the computer, the TV, or her boyfriend, she said “the phone”. Personally, I couldn’t do without the phone entirely, which makes me unusual, Because the telephone is changing our lives more than any other piece of technology.

Point 1 The telephone creates the need to communicate, in the same way that more roads create more traffic. My daughter comes home from school at 4:00 pm and then spends an hour on the phone talking to the very people she has been with at school all day. If the phone did not exist, would she have anything to talk about?

Point 2 The mobile phone means that we are never alone. “The mobile saved my life,” says Crystal Johnstone. She had an accident in her Volvo on the A45 between Otley and Skipton. Trapped inside, she managed to make the call that brought the ambulance to her rescue.

Point 3 The mobile removes our secret. It allows marketing manager of Haba Deutsch, Carl Nicolaisen, to ring his sales staff all round the world at any time of day to ask where they are , where they are going, and how their last meeting went.

Point 4 The telephone separates us. Antonella Bramante in Rome says, “We worked in separate offices but I could see him through the window. It was easy to get his number. We were so near——but we didn’t meet for the first two weeks!”

Point 5 The telephone allows us to reach out beyond our own lives. Today we can talk to several complete strangers simultaneously (同时地) on chat lines (at least my daughter does. I wouldn’t know what to talk about). We can talk across the world. We can even talk to astronauts (if you know any) while they’re space-walking. And, with the phone line hooked up to the computer, we can access the Internet, the biggest library on Earth.

45.How do you understand ‘Point 1 —The telephone creates the need to communicate,…’?

       A.People don’t communicate without telephone. 

B.People communicate because of the creating of the telephone.

       C.People communicate more since telephone has been created.

 D.People communicate more because of more traffic.

46.Which points do you think support the idea that phones improve people’s life?

a.Point 1.  b.Point2.   c.Point3.   d.Point 4.   e.Point 5.

A.c, d B.a, e   C.a, c   D.b, e

47.It is possible to talk to several complete strangers simultaneously through        .

       A.the TV screen               B.a fax machine     

       C.the phone line hooked up to the computer     D.a microphone

48.The best heading for the passage is .

       A.Phone Power                  B.Kinds of Phone 

C. How to Use Phones           D.Advantage of Phones

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
