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.

Modem science had discovered that one lightning contains over 15 million volts. A spark between a cloud and the earth may be as long as 13 kilometers, and travel at a speed of 30 mil lion meters per second.

Scientists estimate that there are about 2,000 million flashes of lightning per year. Lightning hits the Empire State Building 'hi New York J0 to 48 times a year. In the United States alone it 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 under a tree. Also, one should stay out of water and away from metal fences. Inside a house, people should avoid opening doorways and windows and not touch wires or metal things.

听力原文:W: Did you see today's newspaper? That building over in Centerville was just stru
ck by lightning for the fourth time.

M: I didn't read the article, but I'm not surprised. The old proverb says lightning never strikes twice in the same place. But it seems to me that if the conditions for lightning to strike are right one time, they might be just as good another time.

W: Well, I don't take any chances. If I'm caught in a thunderstorm, I look for shelter in a building or a closed car since lightning is supposed to be attracted to the tallest or sharpest object in the area. Also, I was told that if you're stuck outdoors, the best thing you can do is to keep yourself close to the ground and avoid bodies of water. Apparently, lightning is especially attracted to water.

M: To tell you the truth, even when I'm at home I don't take baths or showers during a thunderstorm. I unplug my television and I don't use any appliances or talk on the telephone. I just avoid using anything that works electrically. Maybe I'm too nervous about these things though.

W: I wouldn't say that, According to the article, lightning starts thousands of fires every year in the United States alone. Hundreds of people are injured or even killed by lightning, and millions of dollars worth of property gets damaged. I think you're just being sensible.

What are the man and woman discussing?

A.A weather forecast.

B.Information in a news article.

C.A friend's experience.

D.Details from a recent lecture.

听力原文: Many thousands of years ago, people lived only in hot countries. They did not li
ve in cold countries because they could not keep warm. At first men did not know how to make a fire. Sometimes lightning hit a forest and started a fire. The people took some of this fire to make a fire near their homes. A fire was very important for three reasons. It kept them warm. It frightened wild animals, because they did not attack when they saw a fire. And then another thing was discovered: if you cook food, it tastes much better!

Men still did not know how to make a fire. When they had a fire they did not let it stop burning. If it went out, they could not start it again. They had to wait for lightning to start another fire! Sometimes they had to wait for years.

Later they discovered how to make a fire. If you rub pieces of wood together, they become hot and burn. You have to rub very fast! One way of doing it is to make a little hole in a piece of wood. Pieces of wood or dry leaves are put into the hole. Then you put the end of a stick into the hole. You rub the stick between your hands. This makes it turn very quickly. The end in the hole becomes very hot. The small pieces of wood and dry leaves begin to burn.

Another way of making a fire is to knock two stones together. This makes a spark. You can use this spark to start a fire. Nowadays we have matches. We can carry them in our pockets and make a fire when we want to. We also have cigarette lighters. They are, perhaps, handier and more useful than matches. There are, of course, other advanced methods of making a fire. Many people use heaters to keep warm. Oil heaters bum oil. Gas heaters burn gas. Electric heaters use electricity. We also use oil, gas and electricity for cooking.

How was fire first made?

A.Lightning hit a forest and started a fire.

B.People rubbed two pieces of wood together to make a fire.

C.People knock two pieces of stone together to make a fire.

D.People rubbed a stick between their hands to make a fire.
