I was walking along the main street of a small seaside town in the north of England looking for somewhere to make a phone call. My car had broken down outside the town and I wanted to contact the AA Company. Low grey clouds were gathering across the sky and there was a cold damp wind blowing off the sea which nearly threw me off my feet every time I crossed one of the side streets. It had rained in
the night and water was dripping from the bare trees that lined the street. I was glad that I was wearing a thick coat.
There was no sign of a call box, nor was there anyone at that early hour whom I could ask. I had thought I might find a shop open selling the Sunday papers or a milkman doing his rounds, but the town was completely dead. The only living thing I saw was a thin frightened cat outside a small restaurant.
Then suddenly I found what I was looking for. There was a small post office, and almost hidden from sight in a dark narrow street. Next to it was the town’s only public call box, which badly needed a coat of paint. I hurried forward, but stopped in astonishment when I saw through the dirty glass that there was a man inside. He was
fat, and was wearing a cheap blue plastic raincoat. I could not see his face and he didn’t raise his head at the sound of my footsteps.
Carefully, I remained standing a few feet away and lit a cigarette to wait for my turn. It was when I threw the dead match on the ground that I noticed something bright red trickling from under the box call door

The temperature of the sun is over 5000 degrees Fahrenheit at the surface, but it rises to perhaps more than 16 million degrees at the center.The sun is so much h
otter than die earth that matter can exist only as a gas, except at the core.In the core of the sun, the pressures are so great against the gases that, despite the high temperature, there may be a small solid core.However, no one really knows, since the center of the sun can never be directly observed.
Solar astronomers do know that the sun is divided into five layers or zones.Starting at the outside and going down into the sun, the zones are the corona, chromosphere, photosphere, convection zone and finally the core.The first three zones are regarded as the sun's atmosphere.
But since the sun has no solid surface, it is hard to tell where the atmosphere ends and the main
body of the sun begins.
The sun's outermost layer begins about 10000 miles above the visible surface and goes outward for mllions of miles.This is the only part of the sun that can be seen during an eclipse(日食) such as the one in February 1979.At any other time, the corona can be seen only when special instruments are used on cameras and telescopes to shut out the glare of the sun's rays.
The corona is a brilliant, pearly white, filmy light, about as bright as the full moon.Its beautiful rays are a sensational sight during an eclipse.The corona's rays flash out in a brilliant fan that has wispy spikelike(一束束穗状) rays near the sun's north and south poles.The corona is thickest at the sun's equator.
The corona rays are made up of gases streaming outward at tremendous speeds sad reaching a temperature of more than 2 million degrees Fahrenheit.The rays of gas thin out as they reach the space around the planets.By the time the sun's corona rays reach the Earth, they are weak and invisible.
【小题1】Matter on the aim can exist only in fee form of gas because of the sun's ___.
| A.size | B.age | C.location | D.temperature |
| A.corona | B.chromosphere | C.photosphere | D.core |
| A.hotter | B.clearer | C.thinner | D.stronger |
| A.The remaining layers of the sun. |
| B.The evolution of the sun to its present form. |
| C.The eclipse of February 1979. |
| D.All the above. |
Batteries can power anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri(MU) researchers are developing a nuclear energy source that is smaller, lighter and more efficient.
“To provide enough power, we need certain methods with high energy density(密度)”,said Jae Kwon, assistant professor of electrical and computer engineering at MU. “The radioisotope(放射性同位素) battery can provide power density that is much higher than chemical batteries.”
Kwon and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro/nanoelectromechanreal systems (M/NEMS). Although nuclear batteries can cause concerns, Kwon said they are safe.
“People hear the word ‘nuclear’ and think of something very dangerous,” he said, “However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems.”
His new idea is not only in the battery’s size, but also in its semiconductor(半导体). Kwon’s battery uses a liquid semiconductor rather than a solid semiconductor.
“The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure(晶体结构) of the solid semiconductor,” Kwon said, “By using a liquid semiconductor, we believe we can minimize that problem.”
Together with J. David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery. In the future, they hope to increase the battery’s power, shrink its size and try with various other materials. Kwon said that battery could be thinner than the thickness of human hair.
【小题1】Which of the following is true of Jae Kwon?
| A.He teaches chemistry at MU. |
| B.He developed a chemical battery. |
| C.He is working on a nuclear energy source. |
| D.He made a breakthrough in computer engineering. |
| A.to show chemical batteries are widely applied. |
| B.to introduce nuclear batteries can be safely used. |
| C.to describe a nuclear-powered system. |
| D.to introduce various energy sources. |
| A.get rid of the radioactive waste | B.test the power of nuclear batteries. |
| C.decrease the size of nuclear batteries | D.reduce the damage to lattice structure. |
| A.uses a solid semiconductor | B.will soon replace the present ones. |
| C.could be extremely thin | D.has passed the final test. |
| A.science news report | B.book review |
| C.newspaper ad | D.science fiction story |

阅读下列短文,从每题所给的(A、B、C和D)四个选项中,选出最佳选项,并在答题卡上将该选项标号涂黑。
A
I was in a terrible mood. Two of my friends had gone to the movies the night before and hadn’t invited me. I was in my room thinking of ways to make them sorry when my father came in. “Want to go for a ride, today, Beck? It’s a beautiful day.” ks5*u
“No! Leave me alone!” Those were the last words I said to him that morning.
My friends called and invited me to go to the mall with them a few hours later. I forgot to be mad at them and when I came home to find a note on the table. My mother put it where I would be sure to see it. “Dad has had an accident. Please meet us at Highland Park Hospital”.
When I reached the hospital, my mother came out and told me my father’s injuries were extensive. “Your father told the driver to leave him alone and just call 911, thank God! If he had moved Daddy, there’s no telling what might have happened. A broken rib(肋骨)might have pierced(穿透)a lung...”
My mother may have said more, but I didn’t hear. I didn’t hear anything except
those terrible words: Leave me alone. My dad said them to save himself from being hurt more. How much had I hurt him when I hurled those words at him earlier in the day?
It was several days later that he was finally able to have a conversation. I held his hand gently, afraid of hurting him.
“Daddy… I am so sorry…”
“It’s okay, sweetheart. I’ll be okay. ”
“No,” I said, “I mean about what I said to you that day. You know, that morning?”
My father could no more tell a lie than he could fly. He looked at me and said. “Sweetheart, I don’t remember anything about that day, not before, during or after the accident. I remember kissing you goodnight the night before, though. ”He managed a weak smile.
My English teacher once told me that words have immeasurable power. They can hurt or they can heal. And we all have the power to choose our words. I intend to do that very carefully from now on.

At a meeting, a well-known speaker lifted up a bill of 20 dollars before starting his speech.
Facing 200 people, he asked, “Who wants this 20-dollar bill?” A great many hands were put up. Then he continued to say, “I intended to give it to any one of you, but allow me to do a thing before giving it to you.” Suddenly he crumpled (揉)it into a round mass. Then he asked, “Who wants it? ” Still some hands were lifted up.
He asked again, “Well, how could it be if I do it like this?” he threw the bill onto the ground, stepped on it and twisted it. As he picked it up, the bill had become not only dirty but wrinkled.
“Who still wants it?” Still a few people put up their hands.
“My dear friends, you have had a meaningful class. No matter how I treated this bill, you still want it, because it is worth 20 dollars. On your life road, you may be knocked down(击垮) or even broken into pieces by your determination or unfavorable situations. We may feel ourselves worth nothing, but, my darling, remember that whatever happens in the future, you should never lose your value(价值) in the God’s heart. You’re particular ---- never forget it.”
