矿俗称的瓦斯则是在煤层中以甲烷为主要成分的非常规天然气，热值与常规天然气相当，是通用煤气的2～5倍，燃烧后很少产生污染物，属于优质洁净气体能源。瓦斯爆炸的破坏力，源于它能产生巨大的能量。于是，一个比较直接的减灾措施就是把瓦斯利用起来。这样，不但对人类的危害减小了，同时还可以为人类造福。 对这段文字中“瓦斯”概念的理解，准确的是()

A．是根据英文“GAS”音译而来的、宝贵而洁净的气体能源

B．是能产生巨大的能量，爆炸时具有很大破坏力的气体

C．是蕴藏在煤层中以甲烷为主要成分的非常规天然气，属于优质洁净气体能源

D．是一种燃烧后很少产生污染物的优质洁净气体能源

Radar (雷达)

1. Children enjoy shouting at a high wall and hearing the sound come back to them. These sounds are called echoes (回声). Echoes have given us a number of 'valuable tools.

2. Echo sounding devices were early used in making maps of the ocean floor. Sounds or Ultrasonic (超声的) sounds make good tools for determining how deep the water is under ships. Sometimes echoes from ultrasonic distance finding devices were prevented from working by fish swimming past or by the presence of large objects. So ultrasonic devices have been replaced by other tools.

3. Radar is now a familiar tool. Like many others it was ah unexpected discovery. It was first observed by two researchers, who were studying sound communication. They were sending signals from a station on one side of a river in Washington, D .C. to a vehicle across the river. They discovered that their signals were stopped by passing ships. They recognized the importance of this discovery at once.

4. All this was of course just a start, from which our present radar has developed. The word "radar," in fact, gets its name from the term "radio detection (检测) and ranging." "Ranging" is the term for detection of the distance between an object and the radar set. Today, in our scientific age, it would be difficult to manage without radar.

5. One of the many uses of radar is as a speed control device on highways. When a person in an automobile is driving faster than the speed limit, radar will show this clearly and the traffic police can take measures to stop him.

6. A pilot cannot fly a plane by sight alone. Many conditions such as flying at night and landing in dense fog require the pilot to use radar. Human eyes are not very good at determining speeds of approaching objects, but radar can show the pi lot how fast nearby planes are moving.
