C is sometimes referred to as a 'high -level(66)language'. Some people think that's an insult, but it's actually a deliberate and significant aspect of the language. If you have(67)in assembly language, youll probably find C very natural and comfortable(although if you continue to focus too heavily on machine - level details, youll probably end up with unnecessarily non- portable programs). If you havent programmed in assembly language, you may be frustrated by C 's lack of certain higher - level features. In either case, you should understand why C was de- signed this way: so that seemingly - simple constructions expressed in C would not expand to arbitrarily expensive(in time or(68))machine language constructions when(69). If you write a C program simply and succinctly, it is likely to result in a succinct, efficient machine language executable. If you find that the(70)resulting from a C program is not efficient, it's probably because of something silly you did, not because of something the compiler did behind your back which you have no control over. In any case, there's no point in complaining about C's low - level flavor: C is what it is.

A．assembly

B．combination

C．grouping

D．compounding

听力原文：To extinguish different kinds of fires, several types of fire extinguishers have

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.

(30)

A．Separating the fire.

B．Reducing the heat.

C．Removing the fuel

D．Cutting off the oxygen.
