2017届高考英语二轮复习课件：《科普知识型阅读理解》

　　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 US government agency DARPA. Engineer Richard Mason of the RAND Corporation helped design driverless vehicles for DARPA challenge races. 返回目录专题二十五　科普知识型阅读理解新题预测 “Cars have become much more fuelefficient, and new electronic features are making Hondas safer，”

　　said Angie Nucci of Honda America.“A camera on the passengerside 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. 返回目录专题二十五　科普知识型阅读理解新题预测 “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 cutting down the cost for driverless vehicles from thousands of dollars to something more affordable. He said this will happen as the technology is improved. 返回目录专题二十五　科普知识型阅读理解新题预测 1．What can we learn from Paragraph 1? A．Driverless vehicles are now legal in the whole USA.

But not at the gas pump or electric battery charger—at the air pump! That's not hot air, either! The next generation of cars may run on thin air. Wouldn't that be an incredible way to cut both pollution and dependence on foreign oil? 返回目录专题二十五　科普知识型阅读理解新题预测 If you've ever inflated a balloon and then let it go, you've got the basics to testdrive the amazing MiniCAT, currently being developed by Moteur Development International (MDI), headquartered in Luxembourg. Invented by Formula One racing car designer Guy Negre, this experimental vehicle is unlike any car you've ever seen. While your family's traditional car or SUV draws its horsepower using combustion, the only fuel that MiniCAT needs(CAT stands for Compressed Air Technology) is the air we breathe. 返回目录专题二十五　科普知识型阅读理解新题预测 Start with about 25，000 gallons of air. Now, press it all into a space smaller than your school locker—because that's the size of two superstrong, highpressure air tanks, made from fibre and fixed beneath the air car. Confining that much air inside those small tanks generates an internal pressure of over 4，000 pounds per square inch. That's over 300 times normal air pressure. 返回目录专题二十五　科普知识型阅读理解新题预测 When this cold and highpressure air enters MiniCAT's unique engine, it interacts(交互作用) with warmer air to create pressure waves that pump the engine's engineered pistons(活塞) to move the car. MiniCAT's projected top speed is 60 miles per hour, with a range of 120 miles on a full air supply. 返回目录专题二十五　科普知识型阅读理解新题预测 5．What is the passage mainly about? A．Ways to cut down air pollution.
