In Kansas City, Missouri, a computer helps firefighters. The computer contains information about every one of the 350,000 street addresses in the city. When fire-fighters answer a call, the computer will give them important information about the burning building: its position, size, type and so on. In ’fact, the computer system has almost unlimited ways of helping fire-fighters with the problems facing them. For instance, it can give medical information about invalid living in a burning building. (76)
With this information, the fire-fighters can take special care to these sick persons and remove them quickly and safely.
The Kansas City computer system also keeps a medical record of each of the city’s 900 fire-fighters. This kind of information is especially useful when a fireman is injured. With this medical information, doctors at the hospital can treat the injured fire-fighters more quickly and easily.
The fire-fighters themselves greatly appreciate the computer help. They know about possible dangers ahead of them and can prepare for them. Many times the computer information helps to save lives and property. Sometimes the lives are those of firefighters themselves!

选项
A、is badly burned or injured
B、is trapped by fire
C、has become very weak through illness or injury
D、is helped out by fire-fighters
答案
