[EX Q]: Article: The 9.2magnitude earthquake which caused the tsunami in the Indian Ocean on Boxing Day last year occurred at 7:58 a.m.,95 miles off the west coast of Aceh, Indonesia. Eighteen minutes later.10-metre high waves crashed the ashore along a 500----mile-long stretch of Aceh. Two hours later the tsunami hit Thailand and Malaysia and then Burma, Bangladesh, India,the Maldives,Sri Lanka,Kenya and Somalia.The final death toll is thought to be about 280,000,with tens of thousands more listed as missing.More than l.8 million people lost their homes. *What Is Tsunami? A tsunami is a chain of fast moving waves caused by a sudden strong quake in the ocean.They can be caused by earthquakes,volcanic eruptions ,or even the collision of meteorites .Tsunamis are also incorrectly known as tidal waves,but unlike tidal waves they are not caused by changes in the tides. They are also most common around the edge of the Pacific,where more than half of the world's volcanoes are found.These fast moving waves can attack coastlines,often with little or no warning.Rocks weighing as much as 20 metric tonnes have been pulled from sea walls and carried l 80m inland. *Wave Power Atsunami can have a wavelength in excess of 1 00km and there may be an hour between them.They travel at great speeds across an ocean with hardly any energy losses and are barely noticeable out at sea. Over the deep Pacific Ocean,a tsunami travels at about 800kph.If an earthquake happened in Los Angeles.a tsunami could hit Tokyo quicker than you could fly between the cities by jet. *Strange Animal Behaviors Ten days before giant waves slammed into Sri Lanka and India coastlines,wild and domestic animals seemed to know what was about to happen and fled to safety. Elephants screamed and ran for higher ground. Dogs refused to go outdoors. Zoo animals rushed into their shelters and could not be enticed to come back out.

[EX Q]: Article: You have heard the expression "horse sense". As you may imagine, it came from the time when the majority of people traveled in vehicles drawn by horses. A horse does have a lot of common sense, and there are many true stories about horses having saved their drivers from danger of death. Today for the most part, people travel by train, ship, airplane, and car, but very little by the use of horses. Modern vehicles are _ by engines, and an engine does not have any sense. In case of danger, many horses could be depended on to help. Not so with the engine; the driver must do all the things. In recent years, the speed of travel has increased greatly. With the increased speed comes greatly increased danger. The driver of a powerful engine needs to be careful. A moment of being careless may cost a life. In order to drive today, a person must be able to see clearly, and he must learn and follow carefully the rules for safety on the road. Greater attention is the price we pay for using a machine instead of a horse.
