In Kansas, Missouri, a computer helps firefighters. The computer contains information about everyone of the 350,000 street addresses in the city. When a firefighter answers a call, the computer gives him important information about the burning building. The computer can give the location of the building and its size, type and content.In fact, the computer system has almost unlimited ways of helping firefighters with their problems. For example, it can give medical information about invalids (老弱病残) living in a burning building.The speed of a computer is amazing (惊人的). Within 2 or 3 seconds after a call is received, the computer provides necessary information for the firefighters. The information is then sent to them by the radio from the computer center in the city hall.The Kansas City Computer System also contains a medical record of each of the city’s 900 firefighters. This kind of information is especially useful when a firefighter is injured. With this medical information, doctors of a hospital can treat the injured firefighters more quickly and easily. The firefighters themselves greatly appreciate the help of the computer. They know about possible dangers ahead of them and can prepare for them. Many times the computer information helps to save lives and property, and sometimes the lives are those of the firefighters themselves. How many firefighters are there in Kansas City（）

The strange, close understanding between twins is a familiar enough phenomenon. Often they seem to understand each other and share each other’s emotions to such an extent that one suspects some kinds of thought communication.What is not so widely known is that this special relationship often acts as a brake (障碍) on twins’ intellectual development. As they are partly isolated in their own private world, twins communicate less with adults than do other children. The verbal (口头的) ability of a four-year-old twin is typically six months behind that of a non-twin. The problem can be particularly severe in a deprived home, a one-parent family for example, where there is little stimulation for children anyway.Such children, while capable of mutual comprehension in a private language, often remain incomprehensible to outsiders and thus at a severe educational disadvantage. The only solution to the problem, cruel though it may seem, is to separate the twins, thus forcing them to acquire ordinary speech helped and guided by sympathetic (富有同情心的) parents and teachers. The writer mentions all of the items listed below EXCEPT（）
