Fire can help people in many ways. But it can also be very harmful. Fire can make water hot and house warm, give light and cook food. But fire can burn (燃烧) things, too. It can make trees, houses, animals and other things catch fire (起火). If some people can't run away from fire, it can kill them. This happens in every country every year.

Sometimes big fire can burn forests. A month ago, a large forest fire broke out in Yunnan Province. It lasted nearly half a month. The forest in Heilongjiang Province and the grassland in Inner Mongolia caught fire in May, 2006. After more than ten days' fight, over 30,000 people and soldiers put out (扑灭) the fire at last.

Nobody knows clearly when people began to make fire, but there are many interesting stories about the first time a man or a woman started a fire. One story from Australia tells about a man who went to the sun and brought fire down a long time ago. Today people know how to make a fire with matches (火柴). Children sometimes like to play with them. But matches can be very dangerous. The match can burn a piece of paper and then it can burn a house. A small fire can become a big fire, and destroy many things. Fire kills many people every year. So you must be careful with fire.

Scientist Without Laboratories

When you hear the word “scitentist”, what do you think of? Many people think scientist are people in clean white coats who work in labs. And some scientists do work in labs. But there are   26   scientist who work in woods and jungles. These scientists are called “animal behavior (行为) scientists”, and they study animals as they live in nature.

Why don’t these scientists catch animals and study them in zoos? The   27   is in the word “behavior”. Animals behavior scientists want to learn   28   animal behave in their wild homes. When animals live in cages (笼子) or in zoos, they do not act the same as they do when they are   29  . They may fight   30   each other, or they may not eat, or they may not raise (抚养) their babies as they usually would. To see real animal behavior, scitentists must go where the animals   31  .

So animal behavior scientists go into the jungles, the woods or the desert. There , their most important   32   are their eyes and ears. They watch and listen to the animals very   33  . They write down everything that happened in notebook.   34 

they live near the animals, the scientists are careful not to frighten them. If the scientists are luncky, the animals will   35   no attention to them. Then the scientists can see how the animals really live.

The behavior scientists hope what they’ve learned about animal behavoir can provide clues (提供线索) to help people learn to live together more happily.
