题目

从18世纪中叶开始，主要资本主义国家在生产领域出现了一系列技术发明和革新，大机器生产逐步成为工业生产的主要方式，人类开始步入“蒸汽时代”或工业化时代。这一变化称为（   ） A．文艺复兴         B．新航路的开辟          C．工业革命           D．明治维新 答案：C An Australian company, Smart Car Technologies, has developed a system that lets drivers know when they're speeding. When the technology becomes commercially available, it could help lead-footed drivers avoid tickets and also save lives. The company that developed the product hopes to convince Australian government agencies to put the technology into use in their automobile fleets.The product, called Speed Alert, links real-time location data and speed obtained with the help of GPS to a database of posted speed limits stored in a driver's PDA or programmable mobile phone. The setup of the product does not need to be hooked up to a car's speedometer. In fact, it is entirely portable. It will also work with newer phones and PDAs that have built-in GPS receivers. If a driver exceeds the speed limit, the speed is shown and an alert sounds.Michael Paine, an Australian vehicle design engineer and traffic safety consultant, was hired to analyze the product. He told Live Science that his colleagues in the road safety field are “very enthusiastic” about what they're now calling “intelligent speed alert.” Other research, according to Paine, shows that 40 percent of all traffic deaths involve speeding. There is also a potentially controversial future use: “Since the system is so portable, it would be easy to make it a requirement for teenage drivers to always use a speed alert device when driving,” Paine said. “The system even has the capability to record speeding violations, so parents can monitor their teenage drivers.”The product will soon go on sale in Sydney.63．What's the purpose of the new product?A．To introduce some improvement in cars.B．To inform us of the new car system.C．To popularize the built-in car system.D．To limit certain drivers to safe driving.64．“Lead-footed” in the first paragraph probably refer to the ones ________.A．who drive too carelessly     B．that drive too slowly C．who are partly disabled      D．that drive extremely fast65．The second paragraph mainly talks about ________.A．how the product is programmed     B．why the system becomes popularC．the functions of GPS in cars      D．the project of the built-in product66．Which of the following would be the best title for the passage? A．Future Speed Alert             B．New In – Car Device Against Speeding C．Warning for Adventurous Drivers   D．Progress in Car – making Science
