[单选题]The forty years from the 1930s to the 1970s was an important period

根据材料，完成下面的题目。Air Transportation1. Airplanes are used to carry passengers, cargo and mail. Air transport companies operate scheduled airlines and non-scheduled services over local, regional, national, and international routes. The aircraft operated by these companies range from small single-engine planes to large multiengine jet transports.2. The first air passenger services began in 1910, when dirigibles began operation between several German cities. The first scheduled airplane service to carry passengers began in the U. S in 1914. Several experimental airmail flights took place in India, Europe, and the United States before World War I, but air transport service did not become a true business until after the war.3. During World War Two, intercontinental air transport became firmly established. After the war the new long-distance transports with advanced facilities were increasingly able to avoid storms and strong wind and make flights more economical and consistent. A new generation of "jumbo-jet" transports began operations in 1970, and the supersonic transport entered passenger service in 1976.4. During the 1970s the number of domestic passengers on U. S airlines increased about 78%, and during the 1980s the figure was up about 58%. In 1990 there were 41.8 million international passengers, the figure was a 75% increase over 1980. The total cargo flown by U. S airlines almost doubled during the 1980s, from 5.7 billion to 10.6 billion ton-miles in 1990.5. Major airports provide a wide range of facilities for the convenience of millions of travelers. These range from such basic services as ticket-sales counters and restaurants to luxury hotels, shopping centers and play areas for children. International airports must also have customs areas and currency exchange counters and so on.Paragraph 2__________.

[单选题]阅读材料，回答{TSE}题。The New Technology ApplicationOn a more mundane level, third-generation mobile telephones, despite all the delays and the billions squandered on 3G licenses by telecom firms, are still expected to offer consumers high-speed, always on mobile internet access, complete with video, in the next few years.Rapidly proliferating "WiFi" networks already offer wireless access on a local basis. Tiny tracking chips called radio-frequency identification devices are being used as pet passports.Soon they will be small, powerful and cheap enough to be implanted into everything form humans to milkcartons recording and transmitting real-time medical data, or serving as a form of inventory control.Sensors of every kind, including video cameras, should also become much smaller and cheaper.Forrester Research, a technology consultancy, predicts that 14 billion such devices will be connected to the internet by 2005.How rapidly such new technology is introduced will depend on a number of factors the state of the economy, the supply of investment capital and the appetite of consumers for new products or services ! Fortunes will be made and lost many times over.But whatever happens, the power of computing and communications look set to continue to grow, and its price to fall, at a steady rate for the next few decades.That will make it possible, at least in rich countries, to record most human interactions, wherever and whenever they take place, and to store and analyze this ocean of data at low cost.For the sake of argument, this survey will assume that we are heading towards a networked society of ubiquitous, mobile Communication capable of constant monitoring.Whether this arrives in 20,30 or 40 years does not really matter.The point is that the destination seems not merely possible, but probable, so it is not toosoon to ask: What do we want this technology to do?The internet has already thrown up a host of legal and political conundrums, but, these are only a small foretaste of the dilemmas about privacy, security, intellectual property and the nature of government itself that will have to be faced over the coming decades.The debate has already begun. This survey will outline some of main issues, and speculate on the way they are likely to go.{TS} Radio-frequency identification devices__________.

ale expected to be used as a means to control inventory

解析：【答案】D【解析】本题答案在原文第一段。“Soon they will be small．powerful enough tO be implanted into everything from humans to milk cartons，…0r serve as form ofinventory control．”由此可见，D“无线电频率识别装置将可用来控制存货”为正确选项。
