单项选择题

In early 2004 eight tiny sensors were dropped from a plane near a military base in California. After hitting 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 sens6rs 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

问答题

阅读下列材料并回答问题。
材料1
通州之设纱厂,为通州民生计,亦即为中国利源计。通(通州)产之棉,力耕丝长,冠绝亚洲,为日厂之所必需,花往纱来,日盛一日,捐我之产以资人,人即用资于我之货以售我,无异于沥血肥虎,而袒肉以继之,利之不保,我民日贫,国于何赖下走(我)寸心不死,……今厂工已毕,纱机已开,凡我共事之人,既各任一事以专责成。
              ——摘自张謇《大生纱厂厂约》
材料2
謇意自今为始,凡隶属本部(指农商部)之官业,概行停罢,或予招商承办。
唯择一、二大宗实业,……为一私人或一公司所不能举办,而确有关于社会农、工、商之进者,酌量财力,规划经营,以引起人民兴趣,余悉听民办。謇对于官业之主张,至扩张民业之方针,则当此各业幼稚之时,舍助长外,别无他策。
                    ——摘自张謇《宣言就部任时之政策》(1913年10月)
材料3
中国内地风气尚未尽开,资本又不充裕,试问舍世界各国经济互助,有何别法互助之道无他,即合各国之利病共同,视线一致者,集一银公司,棉铁为主要,……凡有一地一矿一事视为可经营者,……详确其预算,等差其年度,支配其用数,程序其设施,检核其成绩,而又势以平等资本,公开昭布其条件,而互输产品保公司之利,以不犯土地尊主国之权。如是十五年小效,三十年大效,可以预言。
               ——摘自《张季子九录·实业录》卷七
请回答:

根据材料2、3说明为发展中国幼稚的民族工业,张謇提出的重要经济主张和政策。
