听力原文： To extinguish 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 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 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 to 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．Separating the fire.
B．Reducing the heat.

D．Cutting off the oxygen.
Question 37 to 46 are based on the following passage.
It's our guilty pleasure: Watching TV is the most common everyday activity, after work and sleep, in many parts of the world. Americans view five hours of TV each day, and while we know that spending so much time sitting(37)_____ can lead to obesity(肥胖症)and other disease, researchers have now quantified just how(38)_____ being a couch potato can be.
In an analysis of data from eight large(39)_____ published studies, a Harvard-led group reported in the Journal of the American Medical Association that for every two hours per day spent channel(40)_____, the risk of developing Type 2 diabetes(糖尿病)rose 20% over 8.5 years, the risk of heart disease increased 15% over a(41)_____, and the odds of dying prematurely(42)_____ 13% during a seven-year follow-up.

Some nuclear families, however, may add one or more grandparents to come to live with them, that is three generations. This kind of family with grandparents, parents, and grandchildren is called an extended family. This family type was not very common during the later half of the twentieth century, but it's becoming more common now as an elderly grandparent moves in to live with a son or daughter. This is more possible now that American homes have become larger. What is interesting, however, is that after the grandchildren move out of the home and start their own families, this extended family shrinks back to a nuclear family, with just two generations again living together, a grandparent and parents, with the grandchildren coming only for occasional visits.
Now, the fatherless or motherless family is one kind of what we call a single-parent family. In the fatherless family it's just the mother and her children. As I said, this can be the result of the husband's death, of an unmarried mother, of a separation or divorce. There are also a growing number of motherless families--where the father raises the children, for any of the same reasons. A motherless family may also be fatherless, but still a family with one adult. This is becoming more common in the big cities where a grandmother will raise her daughter's children while the daughter goes elsewhere to work.
One other new kind of family is becoming increasingly more common. A single parent with one or more children will marry again. Perhaps the other parent is also a single parent. Together they will start what is called a blended family, which blends together or combines the children from two other families.
An extended family usually has ______.
A．two generations
B．three generations
C．four generations
D．one generation
The means of sending communications are too numerous and varied for a systematic classification; therefore, the analysis must begin with the means of receiving communication. Reception of communication is achieved by our senses. Sight, hearing, and touch play the most important roles. Smell and taste play very limited roles, for they cannot receive intellectual expression from fully developed systems of signs and symbols.
Examples of visual communication are gesture and mimicry. Although both frequently accompany speech, there are systems that rely solely on sight such as those used by deaf and dumb persons. Another means of communicating visually is by signals of fire, smoke, flags, of flashing lights. Feelings may be simply communicated by touch, such as by handshaking or backslapping, although a highly developed system of hand stroking has enabled blind, deaf, and dumb persons to communicate intelligently. Whistling to someone, applauding in a theater, and other forms of communication by sound rely upon the ear as a receiver. The most fully developed form. of auditory communication is, of course, the spoken language.
The means of communication mentioned so far have two features in common: they last only a short time, and the person involved must be relatively close to each other. Therefore all are restricted in time and space.
Why does the author begin his analysis with the means of receiving communication rather than the means of sending communication？
A．Communication actually takes place when the message is received.
B．There are more means of receiving than of sending communications.
C．Reception of communications involves of the senses.
D．It is difficult to organize by type the means of sending communications.
