Last year my sixth-grader daughter ,Elizabeth ,was forced to put up with science .Her education week after week ,contained mindless memorization of big words like “batholith” and “saprophyte” She learned by heart the achievements of famous scientists who did things like “improved nuclear fu-sion（核聚变） “—never mind that she hasn’t the least idea of what nuclear fusion means .Eliza—beth did very well (she’s good at memorizing things ). And now she hates science .My eighth-grader son ,Ben ,also suffered from science education . Week after week he had to perform lab experiments with answers already known .Ben figured out how to guess the right answers ,so he got good grades .Now he hates science ,too.
Science can provide an exciting way to develop children’s curiosity .Science education should teach ways to ask questions and week answers .But my children got the mistaken idea in school than science is difficult dull and has no relation to their everyday interests .
As a physicist ,I am saddened and angered to see “the great science turnoff” I know that science is important in our lives .Yet studies prove that our schools are turning out millions of graduates who know almost nothing about and have almost no interest in science .What’s gone wrong ?Who is to blame ?

To extinguish (熄灭) different kinds of fires, several types of fire extinguishers have been invented. They must be ready for immediate use when fire breaks out. Most portable (手提式的) kinds operate for less than a minute, so they are useful only on small fires. The law requires ships, trains, buses and planes to carry extinguishers.
Since fuel, oxygen (氧气) and heat must be present in order for fire to exist, one or more of these things must be removed or reduced to extinguish a fire. If the heat is reduced by cooling the material below a certain temperature, the fire goes out. The cooling method is the most common way to put out a fire. Water is the best cooling material because it is low in cost and easy to get.
Another method of extinguishing fire is by cutting off the oxygen. This is usually done by covering the fire with sand, steam or some other things. A blanket may be used do cover a small fire.
A third method is called separation, which includes removing the fuel, or material easy to burn, from a fire, so that it can find no fuel.
The method that is used to put out a fire depends upon the type of fire. Fires have been grouped in three classes. Fires in wood, paper, cloth and the like are called Class A fires. These materials usually help keep the fire on. Such fires can be stopped most readily by cooling with water.
