【题目】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.
【1】If a fire breaks out on a bus, which of the followshould 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 _______.
A.separating the fire B.reducing the heat
C.removing the fuel D.cutting off the oxygen
【3】In choosing how to put out a fire, we should first be clear about_______.
A.when it breaks out B.how it comes about
C.what kind it is D.where it takes place
【4】What would the author probably discuss in the paragraph that follows?

【题目】Census Bureau (人口普查局) data released Thursday show that 48 of the 50 most populous (人口稠密的) U.S. cities have grown since 2010, compared with only 40 of the top 50 in the first two years after the 2000 Census. Of the top 100, 93 have grown since 2010, compared with just 72 a decade ago.
Many of the biggest, such as New York, Houston, Phoenix, San Antonio, San Diego and Dallas, are outpacing the nation’s 1.7% growth rate since 2010.
“Urban America is recovering faster than more remote places,” said Robert Lang, a professor of urban affairs.
Only two big cities - Detroit and Cleveland - lost population between 2010 and 2012.
The urban recovery is led by mid-sized cities including Austin and Fort Worth and Charlotte. Austin grew 6.6% in two years, becoming the USA’s 11th-largest city. In 2000, it was No. 17.
Other trends:
New York City grew 2%, adding about 161,500 people since 2010. By far it is the USA’s most populous city.
The population of New Orleans continues to grow. In 2005 a terrible natural disaster happened to the city, causing the population to decrease. Now it has a population of three hundred and sixty-nine thousand. The number has grown by 7.4% since 2010.
Government budget crunches (紧缩) have put state capitals in difficulty. Half are behind the growth rate of their regions.
Perhaps the biggest exception to the capital crunch is Austin. It has grown more than 26% since 2000. Population expert William Frey says Austin enjoys a number of qualities that make it attractive. It’s a high-tech city with a state university. And it’s in Texas, an attractive place for newcomers. “In some ways it’s a model of what other cities would like to become,” he says.
Frey notes that Charlotte, which grew 5.4% since 2010 has grown into a high-tech and financial center whose industries do business not just with those in other U.S. cities but with the rest of the world.
【1】The statistics in Paragraph 1 suggest that _____.
A. there were fewer cities in the USA a decade ago
B. remote areas in the USA have more people now
C. the population in the USA has grown since 2010
D. many big cities in the USA face population problems
【2】William Frey thinks Austin’s growth _____.
A. is due to its education
B. is the steadiest in the USA
C. attracts well-educated people
D. deserves the attention of other cities
【3】According to the text, Charlotte _____.
A. is a political center
B. has grown slowly since 2010
C. is the USA’s 11th-largest city
D. does business at home and abroad

Four Ways to Be a Great Roommate
Having a roommate can be one of the best experiences in college or, easily, one of the worst。 【1】 Follow these tips to avoid the common mistakes that turn good roommate relationships sour.
◇Talk things out.
Communication is key. If something happens, sit down with your roommate and have a face-to-face conversation. I've seen roommate relationships fall apart because something happens and ,instead of talking to each other, the two start complaining about their roommates behind their backs 【2】
◇Don't expect to be best friends.
Some roommates become the best of friends, and some don't. Don't put pressure on yourself or your roommate, especially when you first meet. 【3】 And if your roommate doesn't end up being your best friend, don't worry.
◇Ask before you take.
This applies to food, clothes and anything else. If you want to keep a relationship going, show your roommate that you have respect for what is his or hers by asking first. 【4】
◇Clean up after yourself.
This should do without saying. Don't be lazy. Or, at least, don't bury your roommate in your clothes and garbage. Most people I've come across in college are messy. 【5】 But being considerate with where you put your stuff will help you avoid conflict.
A. So you need to think twice before you help your roommates out.
B. This creates nothing but awkward. situations and unhappiness.
C. Even if you both agree to share
D. You don't have all the time to clean your room and keep it organized.
E. It all starts with you to have a good relationship with your roommate.
F. Sometime you get stuck with someone who has tons of negative energy.
G. Remember, you're trying to make a new friend, not to scare your roommate away.
