Rats eat our food or make it so dirty that it isn't fit for people at all. That's why people often kill them by laying down poison. After a day or two, they find the poison still there. The rats haven't touched it, even though it is near the food which they eat. People think they must be clever and cunning. Some scientists have been trying to find the best way to poison rats. They have watched to see just what a rat does day and night. They have found out that rats aren't so clever. They are just very shy.

　　Rats usually live in holes. They run from these holes to the places where they eat and drink. They have special paths on which they travel each time. So they know their paths quite well.

　　If anything new, such as stone or wood, is put in the path, the rats won't go near it at first as they are too frightened. It will take them many days to get over the fear. They are also frightened to go near a place that they know, where something has been taken away. If a path goes around a rock, the rats follow the same path around the rock each time. If the rock is taken away, they will still run round the place where the rock was! They won't cross the empty place, which is now open to them, even though it would be quicker.

　　Rats will always keep away from anything unusual to them. That's why they won't eat poison on the first or second night. They usually won't go anywhere near it for about four days until they get used to being there. Even then they only eat a little at a time.

　　If people want to kill rats with poison, all they have to do is to leave it out for a few days. Once the rats have got used to it, they will eat it and die.

　　A terrifying example of the sea's power saw about 200,000 people die in 12 different countries last week. The devastation (毁坏) was caused when a massive earthquake sent tsunamis (海啸) smashing into Indian Ocean coastlines.

　　Communities in Sri Lanka. Indonesia, Thailand, India, Malaysia and East Africa have been destroyed by the monster waves. Whole towns were imply swept aside by the power of the water. Cars, trains and buildings could not survive (幸免), let alone the people who stood in the way.

　　The earthquake measured 9.0 on the Richter scale (里氏震级) and occurred off the coast of Indonesia. It was recorded as the fifth strongest since 1900.

　　Scientists said the quake was as powerful as a million of the atomic bombs that were dropped on Japan during World War Ⅱ. “This may be the worst natural disaster in recent history because it is affecting so many heavily populated coastal areas," said Jan Egeland, a UN official.

　　Because such waves rarely happen in the Indian Ocean, there is no system in place to warn coastal communities they are about to be hit.

　　Tsunami is Japanese for “harbour wave.” They are usually caused by a sudden rise or fall of part of the Earth's crust (地壳) under the ocean. Tsunamis often happen in oceans and they are most common in the Pacific. Normally a tsunamis includes a series of waves.

　　Tsunamis can be very long-as much a, 100 kilometres-and be as far as one hour apart. They are able to cross entire oceans without losing much energy. One of the most striking facts about tsunamis is that an earthquake on one side of the Pacific Ocean can cause giant wave, and destruction on the other side.

　　When the ocean is deep, tsunamis can travel unnoticed at speeds of up to 800 kilometres per hour. They can cross the entire ocean in a day or less.

　　The wave may only be a few metres, high in the ocean but when it is near the shore and reaches shallow (浅) water, the wave builds up very quickly in height. Witnesses (目击者) in some areas of Indonesia reported seeing up to 10-metre high waves crash into the shore.
