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.If a fire breaks out on a bus, which of the follow should be ready there for you to use?
A.Sand B.Water C.A blanket. D.An extinguisher.
【 小题2】 To cover a small piece of burning wood with a basin in order to stop the fire is an example of _______.

Glynis Davis:
I first piled on the pounds when I was in the family way and I couldn’t lose them afterwards. Then I joined a slimming(减轻体重的) club. My aim was 40 pounds and I lost 30 pounds in six months. I felt great and people kept saying how good I looked. But Christmas came and I started to slip back into my old eating habits. I told myself I’d lose the weight at slimming classes in the new year…… but it didn’t happen. Instead of losing the pounds, I put them on. I’d lost willpower and tried to believe that the odd bag of fish and chips didn’t make any difference but the scales don’t lie.
Roz Juma:
To be honest, I never weigh myself any more---I’ve learned to be happy with myself. It seemed to me that I would feel sorry about every spoonful of tasty food that passed my lips. My idea is simple. You shouldn’t be too much thinking about food and dieting. Instead, you should get on with life and stop dreaming of a super-thin body. This is obviously the size I meant to be and , most of all, I’m happy with it.
Lesley Godwin:
I was very happy about winning Young Slimming of the Year. I’d look in the mirror unable to believe this slim lady was me ! That might have been my problem—perhaps from then on I didn’t pay any attention to myself. Winning a national competition makes everything worse, though, because you feel the eyes of the world are fixed upon you. I feel a complete failure because I’ve put on weight again.
Ros Langford:
Before moving in with my husband Gavin, I’d always been about 110 pounds, but the domestic bliss(福佑) went straight to my waist and I put on 15 pounds in a year. Occasionally I try to go on a diet…I’m really good for a few days, then end up having the children’s leftovers(吃剩的食物) or eating happily chocolate—my weakness. I’d like to be slim, but right now my duty is the children and home. I might take more exercise when my kids are older.What do you think the four women were all talking about ?

Proverbs(谚语) are quite common in spoken English. We do not normally put them in a composition or letter. Sometimes it is helpful if you know what common proverbs mean. Here are a few examples:
Once bitten, twice shy. If a dog bites me, I shall be twice as careful in future when I see it. This proverb is also used to apply to many things and not only to dogs. If you have been cheated at a shop, you will not go to the same shop again.
A bird in the hand is worth two in the bush. If I am a hunter, trying to catch birds, it is better to catch one bird than to see two birds in a bush but not be able to catch them. Thus this means that what you have already got is better than the chance of being able to get something bigger in the future.
Too many cooks spoil the broth(soup). When too many people do something together, they get in each other’s way and cannot do a good job.
To pour oil on troubled waters Is to try to calm things down. Oil is lighter than water. If a ship is in trouble at sea, another ship may come to help it. The second ship can send small boats to rescue people. However, it may first pour oil on the sea to make the sea less rough.
Don't be a dog in a manger(马槽). Means “ Don’t be selfish.” In a stable(马厩), the manger is the place where the horse’s food is put. Sometimes a dog will sleep in the manger and bard when a horse comes to get its food. The dog does not want to eat the hay in the manger but it will not let the horse eat it.
He’s sitting on the fence. Means that somebody will not say whether he is in favour of a plan or against it. He is sitting on a fence between two opposing sides, perhaps waiting to see which side will win.
He who pays the piper calls the tune. A piper is a musician . The man who employs or pays a musician can say what tunes the man will play. Thus this means that if a man provides the money for a plan, he can say how it will be carried out.
You can’t get blood out of a stone means that you can’t get something out of a person who has not got any of the things you want. For example, you cannot get a million dollars from a poor man.Peter had a bicycle which was much too small for him but he did not want to let his younger brother ride on it.

I am Sergey Brin! I was born in Moscow. In 1979,when I was 5, my family immigrated to California, USA . I remember that on my 9th birthday, I got my first computer “Commodore 64”.
Later I graduated with honors in the University of Maryland in Mathematics and IT. The main field of my science research was the technologies used to collect data from unsystematic sources as well as large quantities of texts and science data. I was the author of dozens of articles in leading American academic magazines.
The greatest event in my life happened when in 1998 I was preparing for the defense(论文答辩) of my Doctor’s degree in the Stanford University. There the fate made me meet Larry Page—a young computer genius. Larry belonged to the intellectual society. I and Larry quickly became friends when we were working together.
We were searching day and night on the Internet. We were finding a lot of information but with the feeling we still couldn’t find enough of what we were looking for . Naturally the idea for a search engine that would allow specific information to be found in the endless pool of data was born like it came to us. It wasn’t our plans but we gave up the education at the university. You know the next part ,maybe—we managed to turn an ordinary garage in Peplo Park, California , the USA into our first office, in which Google was born. With excitement we typed the name of the thing which we created with love on September 14th,1998—www.Google.com. Now after those years we bought this garage. As a symbol it will always remind us that everything is possible. Which of the following would be the best title for this passage?
| A．The Birth of Google | B．The Founder of Google |
| C．The Importance of Cooperation | D．The Great Contribution to the Internet |
From the passage we know that Larry Page________.
| A．was born from a rich merchant family |
| B．was once a student in the Stanford University |
| C．published some academic articles when young |
| D．was Brin’s important partner in starting Google |
Why did they found Google ?
| A．Because they loved working with the Internet so much. |
| B．Because they wanted to make a lot of money through the Internet |
| C．Because they hoped to make it easy to find specific information online |
| D．Because they believed everything is possible. |
Which is the right order of what happened ?
a. My family moved from Russia to the USA
b. I met Larry Page
c. I was given a computer as a present on my 9th birthday.
d. google was born in an ordinary garage in California.

Dear Alice,
You really have two different questions here, so we’ll discuss them one at a time. Your problems at school may be a result of a number of things . You don’t say much about how these classmates get along with each other. It’s possible that all the students are feeling a little cautious(谨慎的) in the first term.
It’s also possible that the others are unkind. If this is so, you have to find out why you are the class “outsider”.
In your letter you say you often offer to help others with their work. Is it possible that your classmates don’t understand your offers? Could it seem that you were trying to “ buy” friends with these offers?
Is it possible that you took no notice of your classmates when you had your good friends near you ? They may have felt hurt at that time. It may take a time for them to believe in you if so. Try to ask one classmate directly what the problem is. If you hear a negative answer, at least you’ll know what to do.
Yours truly,
SheliaFrom the letter we know that Alice was very _______.
| A．lucky | B．unkind | C．clever | D．unhappy |
