There are many ways of putting out a fire. You may have seen people put out burning cigarettes by stepping on them. Stepping on cigarettes shuts off the air and puts out the fire.
Many fires are put out with water. Water cools the materials that are burning. It helps make the fire die out. Some of the water is changed into steam when it strikes the hot fire. The steam keeps air from the fire and helps put it out.
Some fires can not be put out with water. Suppose a tank full of gasoline(汽油)is on fire. Gasoline is lighter than water. If you poured water into the tank of gasoline, the water would sink to the bottom of the tank. The gasoline would float on top of the water on the fire and flow over the edge of the tank. Then the fire would spread. Gasoline fires should be put out with sand or with chemicals of some kind, such as that used in some fire extinguishers(灭火器).

When Webster was young，he was a teacher. But he quickly became tired of the books he used in class. They were all about the English people and places. Since he wanted books that would be interesting to the American children，he wrote three books with many American examples.
Webster worked hard to change the spelling of American English. He wanted words to be spelled in the same way they were pronounced，for example，he thought the word “laugh” should be spelled “laf”. And he tried many ways to ask people to help him do this.
One day he walked into a print shop and gave the boy there a piece of paper. “Young man，”he said，“when you print any book in the future，please don't spell the words like the English people do. For example，when you see these words：theatre，centre, colour，and labour，please always print them as theater，center，color and labor.” The boy studied it and answered，“I agree with you，but I must ask my boss first.”
With the money he made from his books，Webster could start his great work，which took him more than twenty years to finish the first American English dictionary. And today，Webster's dictionary is thought to be the most important American English dictionary in the whole world.
1.Webster didn't like the books used in American schools because________
A．he was born in America

After a study showed that one in every ten meals in the country may be cooked in with dirty oil, the State Food and Drug Administration (SFDA) on Thursday issued an emergency notice （发布紧急通知）to restaurants nationwide, warning them against recycling oil.
The swill-oil is cooking oil refined from kitchen waste that has been recycled. Although it looks clean and clear, it’s actually so dangerous to people’s health that it may cause cancer.
According to a report, the swill-oil business is extremely profitable. Recycling one ton of kitchen waste will produce 130 kg of swill oil. With its price being half that of normal cooking oil, a profit（利润）of 1.5 to 2 billion yuan is produced in the whole swill-oil business in the country every year. The profit is almost 200%, so it’s easy to understand why the business is so hot.
He Dongping, a professor from Wuhan Polytechnic(WHPU) said, “To stop the use of dirty oil should start at its source, kitchen waste. And the first step is to find a good way of collecting kitchen waste.” “However, it might take about 10 years before China could solve the problem completely,” he added.
1.According to the study, ______ of us may have eaten the food cooked by dirty oil.
A. few B. nobody C. many
2.The underlined sentence “the swill-oil business is extremely profitable” means that the swill-oil business is really a ________.
A. big money-maker
B. common situation
C. terrible thing
3. We can infer（推断）from this passage that _______.
A. the biggest problem is that restaurants produce too much kitchen waste.
B. the way of dealing with kitchen waste isn’t good enough now.
