People in several American states may be surprised to see cars on city streets without a driver. Experimental driverless vehicles now are legal in Florida, Nevada and California. They are pointing the way to a future that is not far down the road. The high-tech company Google has a number of self-driving cars, which had covered 480,000 kilometers by August. Volvo is among the companies doing road tests and says it plans to sell driverless cars by 2020.

In September, California Governor Jerry Brown signed an act to allow autonomous vehicles on the roads of his state. " Today we're looking at science fiction becoming tomorrow's reality-the driverless car. " The technology for these cars includes cameras, radar and motion sensors. The systems have been improved through competitions sponsored by the U. S. government agency DARPA. Engineer Richard Mason of the Rand Corporation helped design driverless vehicles for DARPA challenge races.

Cars have become much more fuel-efficient, and new electronic features are' making Hondas safer, said Angie Nucci of Honda America. " A camera on the passenger-side mirror actually engaged on your guiding screen so you can safely change lanes. " Other safety features include warning systems on the front and the sides of the cars. These systems help drivers , but don't replace them. Curator Leslie Kendall of the Petersen Automotive Museum said autonomous cars will make the high ways safer.

"By taking out drivers, you also remove most risks of an accident," Kendall said. He said consumers, however, may be unwilling to lose control. "It may take them time to come to realize that the technology is indeed reliable, but it will have to prove itself first. "

Mason said the technology already works and the biggest challenge now is getting down the cost for driverless vehicles from hundreds of thousands of dollars to something more affordable. He said this will happen as the technology is improved.

(20分)春节期间,中央电视台派出几十路记者“新春走基层”,在各地进行“家风是什么”海采。节目播出后,引发人们对家风的热议。阅读材料,回答问题。

家风,又称门风,是指一个家庭或家族的传统风尚或作风。家庭作为社会的细胞,家风不仅是民风社风的组成要素,也是中 * * 传统价值观的重要组成部分。家风正,则民风淳;家风正,则政风清;家风正,则党风端。例如,晚清重臣、湘军的创立者和统帅曾国藩在治家与治军实践中概括了“八本八宝"的曾氏家训。所谓“八本”,就是“读书以训诂为本,诗文以声调为本,事亲以得欢心为本,养生以少恼怒为本,立身以不妄语为本,居官以不要钱为本,居家以不晏起为本,行军以不扰民为本”。所谓“八宝”,就是“书、蔬、鱼、猪、早、扫、考、宝”。“八本八宝”的曾氏家训,即便放在今天,对提高个人素质和形成良好社会风尚仍有很大的借鉴意义。

(1)结合材料,分析中央电视台进行“家风”海采,引发人们热议家风的文化意义。(8分)并为弘扬一个家庭或家族的传统风尚提出两条建议。(4分)
