Unit 9: The power of nature

Tape Script

Amena : We’ve been learning that some people are afraid that the light from the sun might go out permanently during an eclipse.
Professor: Really? Well, that couldn’t happen, of course. But people are right to think that the sun’s very important.
Shahd : Yes that’s right. If we didn’t get heat and light from the sun, there would be no life on Earth, would there?
Professor: Definitely not! Human beings have always understood this.
Shahd : So, what exactly is the sun, Professor?
Professor: It’s a giant ball of hot gases, which is 150 million kilometres from the Earth.
Amena : Wow! As far as that! Do we know how hot it is?
Professor: Yes, we do have this information. The surface of the sun is about 6,000 degrees centigrade, but if you took the temperature at its centre, you’d find it was more like 15 million degrees.
Shahd : That's incredible.
Professor: The sun gives us heat and light, which we eat, but it also gives out x-rays and ultraviolet rays, which can be very harmful to life.
Shahd : Really? Can you explain why they don’t harm us, then?
Professor: I’ll try and explain. Most of these rays are absorbed in the atmosphere, so they aren’t able to affect us. But I ought to warn you about one very important thing.
Shahd : What that?
Professor: The sun is incredibly strong and you should never look straight at it. If you look at the sun, you’ll damage your sight.
Shahd : Is it OK if you look at the sun wearing sunglasses?
Professor: No, I’m afraid it’s not. A friend of mine thought that, but he now has problems with his eyes. If he hadn’t looked at the sun, he wouldn’t have damaged his sight. Just remember, never look at the sun.

Reading: The Power of Nature

 For most people, the word weather means the sun, rain, wind or snow. If you live in southern Europe or Africa, you know that temperatures are higher and there is less rain than if you live in northern Europe or Canada. It is unusual for a weather forecast to surprise us.
 However, strange weather can occur all over the world. For example, people have seen giant pieces of ice falling from the sky. And what would you think if you saw a ball of light as big as a football on a plane, or floating through your home? Weather experts called these ball lightning.
(1)
 Some storms are very unusual and may cause terrible damage. The English town of Dunwich was once an important port, but in the fourteenth century, high waves and violent storms hit the area and most of the town disappeared beneath the sea. The worst storm in Britain, in 1703, killed more than 8000 people. The worst flood in history was in 1887 in China when the Yellow River flooded and killed around a million people.
 Unusual weather is becoming more common, with very high or low temperatures and very heavy rainfall all over the world. This causes serious droughts in some places and floods in others. However, this is not a modern phenomenon: in Europe in the eighteenth century, there was a Little Ice Age when rivers like the River Thames in England froze.
 What will happen to our weather in the future? No one really knows, but one day ‘unusual’ weather may not be unusual anymore.

5-Read the following passage, then answer the questions:
We may know there's a scientific explanation for solar eclipses, but they continue to have a magical power over us. During a total solar eclipse, people can go blind by the tempting sight of an eclipsed sun. We don't beat drums, fire arrows into the sky, and stand up to our necks in water to appease يهدئ the gods as did the ancient Chinese and Indians. They thought a snake attacked the sun during an eclipse. Noise making was an effort to scare the creature away. The earliest recorded eclipse was in China on October 22, 2134 BC. Then two court astrologers lost their heads because they had failed to predict it. In the fourteenth century B.C., an eclipse was described by a Chinese seer as three flames eating the sun.
Eclipses have been seen as evil omens whose presence changed the course of battle. In the eclipse of 585 B.C., the one Thales is said to have predicted - five years of fighting ended between the Medes and Lydians as a result of an eclipse. The Babylonians were the first to calculate the regular intervals at which eclipses occur. It was through contact with the East that Thales of Miletus was able to make the prediction that marked the beginning of the Greek scientific era. Thales predicted a total solar eclipse in the midst of the battle between Media and Lydia. There is some doubt as to whether Thales accurately predicted the eclipse because he didn't fully understand all the cycles necessary to calculate the date.

6-Read the following passage, then answer the questions:
Hibernation السبات الشتوى is one of the main adaptations تكيفات that allow certain northern animals to survive long, cold winters. Hibernation is like a very deep sleep that allows animals to save their energy when there is little or no food available. The body functions of ‘true hibernators’ go through several changes while they are hibernating. Body temperature drops, and the heart rate slows. For example, a hibernating woodchuck’s body temperature drops by more than 30 degrees Celsius, and its heart rate slows from 80 to 4 beats per minute! Other true hibernators include the jumping mouse, little brown bat, eastern chipmunk, and several ground squirrels. Other animals, such as the skunk and raccoon, are not considered true hibernators, as they wake up in the winter to feed, and their body functions do not change as much. Since they only sleep for a little bit at a time, the term dormancy or ‘light sleeping’ is used to describe their behavior. Hibernating animals have a special substance in the blood called hibernation inducement trigger, or HIT. This substance becomes active in the fall, when the days become cooler and shorter. When HIT becomes active, the animals start preparing for winter. Some animals store food so that they can eat when they wake up, and some animals eat a lot in late summer and fall to add excess fat to their bodies. This fat keeps them warmer and acts as a source of energy while they are sleeping. Some animals also make changes to the places where they will sleep. They add leaves and grasses to keep them warm.

A) Give short answers to the following questions:
1- What changes occur in the functions of an animal’s body when it hibernates?
2- Why are raccoons and skunks not ‘true hibernators’?
3- How do animals prepare for hibernation?

a) in the winter b) in the summer c) in the spring d) in the fall

a) hibernation b) dormancy c) deep sleeping d) true hibernators
