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.

A friend of mine, in response to a conversation we were having about the injustices of life ,asked me the question,“Who said life was going to be fair, or that it was even meant to be fair?” Her question was a good one. It reminded me of something I was taught as a youngster :life isn’t fair. It’s a disappointment, but it’s absolutely true .One of the mistakes many of us make is that we feel sorry for ourselves, or for others ,thinking that life should be fair, or that someday it will be .It’s not and it won’t be .
One of the nice things about surrendering (屈从)to the fact that life isn’t fair is that it keeps us from feeling sorry for ourselves by encouraging us to do the very best we can with what we have . We know it’s not “life’s job ”to make everything perfect :it’s our own challenge .Surrendering to this fact also keeps us from feeling sorry for others because we are reminded that everyone is dealt a different hand ; everyone has unique strengths and problems in the process of growing up, facing the reality and making decisions; and everyone has those times that they feel unfairly treated.
The fact that life isn’t fair doesn’t mean we shouldn’t do everything in our power to improve our own lives or the world as a whole. To the contrary , it suggests that we should .When we don’t recognize or admit that life isn’t fair ,we tend to feel pity for others and for ourselves .Pity ,of course ,is a self –defeating emotion that does nothing for anyone ,except to make everyone feel worse than they already do .When we do recognize that life isn’t fair, however ,we feel compassion (热情)for others and for ourselves. And compassion is a heartfelt emotion that delivers loving-kindness to everyone it touches .The next time you find yourself thinking about the injustices of the world, try reminding yourself of this very basic fact .You may be surprised that it can make you out of self-pity and into helpful action.The writer thought of his friend’s question as a good one because .
| A．he also wanted to know who held such an opinion |
| B．it made him recall something during his childhood |
| C．like his friend , he also thought life was unfair |
| D．he learned something from the question as a youngster |
The second paragraph of the passage mainly tells us that .
| A．it’s nice to accept the injustice of life | B．it’s nice to surrender to life |
| C．we should not feel sorry for everything | D．we should not surrender to life |
From the passage, we can learn that the author’s attitude to life is.
| A．negative | B．positive | C．self-pity | D．indifferent |
Which of the following could be the best title of the text ?
| A．A Helpful Action: Try to Feel Compassion | B．A Good Question: Why Life Isn’t Fair |
| C．Do Our Best to Improve Ourselves | D．Surrender to the Fact That Life Isn’t Fair |

There is, for many of us, a moment in life when we make a choice that changes us forever. This moment marks a turning point, when we realize that the life we're living is not a mirror of who we really are.
For some, the moment comes as a result of something dramatic: the sudden loss of a job, or the death of a loved one. For others, they have to deal with difficult situations, such as financial hardship. In these challenging times, it's more critical(关键时刻的) than ever for us to seize the possibility of positive change. As I travel and talk to people about their lives, I often see a distant, vacant look in their eyes -- a look that says “I’m so busy trying to survive my life that no soul left to live it”.
As a result, we end up feeling lonely. Yet we keep on going the way we've been going. We tolerate high levels of stress at work, take important relationships for granted, or put our health needs on hold. We get so caught up in the details of living that our busyness becomes an excuse from the inner voice that begs us to listen. When you finally pay attention to that little voice and begin to make even small changes, you will slowly improve yourself.
To start positive change, you need the power of your mind. I've come up with a five-step strategy that will help you. You will be able to identify what you want and then go after it. It's easier than you might think.
1. Reset your happiness set point. Don't limit yourself! When I decided that I wanted more control over my life, I set goals in physical, emotional, financial, professional, material, and play. I challenged myself to consider every possible choice. Imagine things you've never believed you could achieve. Don't let your past determine your future.
2. Trust your courage. Too often, when you're first learning to take control of your life, you doubt yourself. It's important to develop a strong connection with your inner guidance system. I've heard many stories about the persistent voice inside your head.
3. Take action. Once you have set goals, adjusted your beliefs, and got ready, you can start making things happen. Again, turn to those people you respect -- the ones achieving what you desire -- for support and guidance. They will both inspire you and give you practical advice on what steps you need to take.
4. Have faith. Believe that the positive energy of grace will support your efforts to improve your life. When you've done all you can, let go and trust that the right result will occur. When we have faith, we give up the need to be in control, and we set ourselves up to actually enjoy the process of change.
5. Be patient. This can be the toughest step. It's not easy to trust that your life will improve in a best way. Remind yourself of the benefits of patience. In my experience, those life changes are always worth the wait.What does the author intend to say in the second paragraph?
| A．The start of some turning points in one’s life is caused by crisis. |
| B．Loss of a job or the death of a loved one are all dramatic things. |
| C．No one can live a life without any turning points. |
| D．No one can predict his future of being good or not. |
In the author’s opinion, we should ______________.
| A．adjust our beliefs from time to time | B．always control ourselves for anything |
| C．keep on going the way we are going | D．seize the challenging times to live an active life |
The author suggests that when setting your happiness set points, you should _______.
| A．know the limitation of your set point | B．build self-confidence without doubt |
| C．limit your goals in different ways | D．consider every possible choice with care |
Which of the following is NOT true according to the passage?
| A．When you've done all you can, you may believe that the right result will occur. |
| B．When you set goals, and take action, it is possible to make things happen. |
| C．When you first learn to take charge of your life, you will always doubt yourself. |
| D．If things do not happen in a way that is best, patience is always worth the wait. |
