Music and Driving
Listening to loud music while driving can seriously hamper reaction times and cause accidents, new research suggests.
A Canadian study found people took．up to 20% longer to perfer,physical and mental tasks to loud music．If motorists were delayed that long at the wheel they could suffer a fatal crash, warned the RAC Foundation, a British motoring organization．Edmund King,the RAC Foundation's executive director, said the study showed that "not only is loud music a nuisance to others, it could also be the cause of accidents".
Earlier research by the RAC Foundation found drivers were twice as likely to skip a red light while listening to music．In the Canadia/a study volunteers carried out tasks while listening to levels of noise varying from 53 .decibels (equivalent to an office environment) to 95 decibels (equivalent to an oil rig)．Researchers found reactions to be significantly decreased at higher noise levels for both physical and mental work．At 95 decibels reaction
times to tasks that involve decision making plummeted (骤然减少) by 20%．Edmund King said: "The findings of the Canadian study are bad news for decibel-loving drivers, as they prove that not only is loud music a nuisance to others, it could also be the cause of accidents on the roads．" Drivers are at even greater risk if they listen to music with a pounding beat rather than more relaxed tunes, according to experts.
Conrad King, consultant psychologist to the foundation, said.．"It is important that drivers choose their music carefully when driving, as up-tempo music has been shown to cause drivers to have double the amount of accidents as those listening to slower music．"In general, if music is above 60 beats per minute, listeners experience a faster heart rate and increased blood pressure．"It doesn't matter if you listen to opera, classical or the latest rave music．It's the speed of the beat that counts．"

Ford
Ford's great strength was the manufacturing process, not invention.Long before he started a car company, he was an inveterate (契而不舍) tinker (喜欢小修小补的人),known for picking up loose scraps (碎片)of metal and wire and turning them into ma-chines.He's been putting cars together since 1891.Although by no means the first popu-lar automobile, the Model T showed the world just how innovative Ford was at combining technology and market.
The company's assembly line alone threw America's Industrial Revolution into over-drive(加速挡).Instead of having workers put together the entire car, Ford's cronies(密友), who were great tool and die (金属模具)makers from Scotland, organized teams that added parts to each Model T as it moved down a line.By the time Ford's sprawling(占地巨大的)Highland Park plant was humming along in 1914, the world's first automatic con-veyor belt(传送带)could turn out a ear every 93 minutes.
The same year Henry Ford shocked the world with what probably stands as his grea-test contribution ever, the $5-a-day minimum wage scheme.The average wage in the auto industry then was $2.34 for a 9-hour shift.Ford not only doubled that, he also took an hour off the workday.In those years it was unthinkable that a guy could be paid that much' for doing something that didn't involve an awful lot of training or education.The Wall Street Journal (《华尔街日报》)called the plan "an economic crime," and critics everywhere heaped "Fordism" with equal scorn.
But as the wage increased later to daily $10, it proved a critical component of Ford's quest to make the automobile accessible(易取得的)to all.The critics were too stupid to comprehend that because Ford had lowered his costs per car, the higher wages didn't mat-ter except for making it feasible(可行的)for more people to buy cars.
