听力原文: In the earliest times, men considered lightning to be one of the great mysteries of nature. Some ancient people believed that lightning and thunder were the weapons of the gods. In reality lightning is a flow of electricity from high above the earth.
The American scientist and statesman, Benjamin Franklin, was the first to show the connection between electricity 'and lightning in 1752. In the same year he also built the first lightning rod. This device protects buildings from damage by lightning.
In the United States alone lightning kills an average of one person every day. The safest place to be in case of an electrical storm is in a closed car. Outside, one should go to low ground and not get under trees. Also, one should stay out of water and away from metal fences. Inside a house, people should avoid opening doors and windows and touch wires or metal things.

The young man asked, "How, Mr. Addison, can you invent so many things and achieve your fame?"
The scientist said, "It seems that you have been thinking of becoming famous every day."
The young man nodded, "Yes. I have been dreaming of being a person as notable as you. Every minute I am thinking of how to become reputable. I don' t know when I can achieve my fame."
Addison told him, "Don't worry, young man. If you want to be a famous man this way, you will have to wait until you die!"
"Why should I?" the young man was puzzled.
Addison said, "What you dream is actually a high building. You never think of how to build it with bricks. Thus the building will never come into reality. However, your story can serve as a mirror. People will remember you because of your illness and laziness. They will often speak of your name while they give warnings to their children. Aren't you a notorious person by then?"
What happened to Addison when he was on his way home?
A.A beggar stopped him
B.A robber stopped him
C.A man wanted to speak to him

M: Yes, well, I've been looking into the ability of certain animals to freeze themselves for a certain amount of time, and then to come back to life when the circumstances around them change. And, what I've been working on over the past two years is the particular process that enables them to do this.
W: What have you actually discovered?
M: I think it's a particular chemical in the animals' bodies which begins to work under certain circumstances. And I'm now experimenting with this chemical to see if I can get other animals that wouldn't normally be able to freeze themselves to be able to do this.
W: Have you had any success?
M: I have so far. It's been going very well. And I'm reasonably confident that perhaps within ten years from now I'll be able to freeze human beings for as long or as short a time as I would like to, and then bring them back to life again in exactly the same state that they were in before they were frozen ... just as you can do with animals.
W: And what's the main application of your research?
M: I think the main application of this for human beings would be for people with terminal illnesses, such as certain types of cancer, AIDS. we could freeze them, find a cure for the illness and then bring them back to life again and administer the cure.
W: I see. Well, this obviously is going to create great debate I would think as to the rights and wrongs of whether we should be actually doing this.
What does Professor Morgan do?
A.He is a film director of Science Fiction.
B.He is a writer of Science Fiction.
C.He is a scientist who researches on how to freeze a body and bring it back to life later.
D.He is a doctor who treats terminal illnesses.

A scientist helped to wire the school, He says, "Here is a plan to connect 12 thousand California schools to the Internet."
Wiring schools in California can cost a lot of money. It needs to be done by volunteer effort or schools will not be able to afford it. They think that it will cost as much as fifty billion dollars.
Some people say that the money should be spent on teachers instead of computers. Some people say that it would be worth it to wire all of classrooms.

听力原文: Some of the most interesting buildings in the world are the pyramids. Thousands of years ago in Egypt, kings built the pyramids. They used to build them as tombs. They thought pyramids would help them find life after death. They also wanted the world to remember them as important people. There are many pyramids along the Nile River. The largest is the pyramid of Khufu. It is made of 2,300,000 huge stones, most of which are higher than a person. It is about 144 meters high. To build this pyramid,100,000 men worked for twenty years.
The people of Mexico also built pyramids. They didn't build the pyramids for tombs. They used to build a pyramid and then build a temple on top of it. The pyramids of Mexico are not as high as those of Egypt, but they are big. Each pyramid has a stairway that goes from the bottom to the top. The biggest pyramid in Mexico is almost 2,000 years old. Scientist's think it took 10,000 men more than ten years to build. On top they built a temple to the sun. The temple is no longer there, but people call it the Pyramid of the Sun.
Scientists have studied the pyramids, but nobody can say just how the people of the ancient days built the pyramids and how they carried and lifted the huge stones. Each stone fits so well and they didn't have our modern machines Z.
(33)
A.They built the pyramid in honor of the gods.
