“老坛酸菜”在古籍《周礼》中称“zn”。 (1) 酸菜常采用大白菜或芥菜腌制而成,在种植白菜时,若发现其易倒伏,易感染虫害,则需施加适量的肥,还能保证各种代谢过程的顺利进行; (2) 腌酸菜时,要将食盐撒在白菜上,日常生活中的食盐是食用加碘精制盐。碘是人体必需的微量元素之一,其原子结构示意图如图所示则其质子数为:。 (3) 酸菜炖肉香而不腻,含有丰富的营养素,瘦肉中主要富含构成细胞的基本物质的。 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
