Passage ThreeIn early 2004 eight tiny sensors were dropped from a plane near a military base in California. After hit ting the ground, the sensors—also known as smart dust sensors organized themselves into a network and quickly detected a fleet of military vehicles on the ground. They determined the direction, speed and size of a series of military vehicles traveling along the road and later transmitted the data to a computer at a nearby base camp.Smart dust sensors are minicomputers—as small as a grain of rice in some cases—that can monitor and evaluate their physical environment and can relay the information via wireless, communication. They can monitor elements such as temperature, moisture, humidity, pressure, energy use, vibration, light, motion, radiation, gas, and chemicals. These devices will soon have many applications, such as use in emergency rescue.Software has been developed to run these minicomputers. A key feature of the software is the ability of the sensors to automatically organize themselves into a communications network and talk to each other via wireless radio signals. If any one connection is interrupted, the sensors will self-correct and pass the information on to the next available sensor.Each sensor has a chip that does the computing work recording things like temperature and motion at its location. Each sensor also has a tiny radio transmitter that allows it to talk to other sensors within 100 feet or so. With a single network of 10,000 sensors—thought to be the biggest array (排列) of sensors currently possible, you could cover 9 square miles and get information about each point along the way. The data finally works its way to a base station that can send the information to a computer or to a wireless network.The scientists who are working with this technology say smart dust sensors can be used to detect the location or movement of enemy troops in areas too dangerous or remote for soldiers to operate. Scattering hundreds of self-networking sensors from a manned or unmanned plane onto the battlefield, in theory, could produce critical information and lead to strategic advantage. Sensors could also be used to detect the presence of chemical weapons and could give troops the time needed to put on protective gear. Smart dust sensors can do all the following EXCEPT ().
A. giving troops their protective gear
B. organizing themselves into a computer network
C. detecting the movement of military vehicles nearby
D. operating in remote and dangerous War zones
War may be a natural expression of biological instincts and drives toward aggression in the human species. Natural (1) of anger, hostility, and territoriality are expressed (2) acts of violence. These are all qualities that humans (3) with animals. Aggression is a kind of (4) survival mechanism, an instinct for self-preservation that (5) animals to defend themselves from threats to their existence. But, on the other hand, human violent (6) evidence of being a learned behavior. In the case of human aggression violence can not be (7) reduced to an instinct. The many expressions of human violence are always conditioned by social conventions that give (8) to aggressive behavior. In human societies violence has a social (9) : It is a strategy for (10) the powers of violence. We will look at the ritual and ethical patterns within which human violence has been (11) .The violence within society is controlled through (12) of law. The more developed a (13) system becomes, the more society takes responsibility for the discovery, control, and punishment of violence acts. In most tribal societies the only (14) to deal with an act of violence is revenge. Each family group may have the responsibility of personally carrying out judgment and punishment (15) the person who committed the offense. But in legal systems, the responsibility for revenge becomes depersonalized and (16) The society assumes the responsibility for (17) individuals from violence. In cases where they cannot be protected, the society is responsible for (18) punishment. In a state controlled legal system, individuals are removed from the cycle of revenge (19) by acts of violence, and the state assumes responsibility of their protection.The other side of a state legal apparatus is a state military apparatus. (20) the one protects the individual form violence, the other sacrifices the individual to violence in the interests of the state. Read the following text.
