根据材料，回答问题。Ford's Assembly Line
When it comes to singling out those who have made a difference in all our lives, youcannot overlook Henry Ford. A historian a century from now might well conclude that it wasFord who most influenced all manufacturing, everywhere, even to this day, by introducing anew way to make cars -- one, strange to say, that originated in slaughterhouses (屠宰场).
Back in the early 1900's, slaughterhouses used what could have been called a "disassemblyline". Ford reversed this process to see if it would speed up production of a part of anautomobile engine called a magneto. Rather than have each worker completely assemble amagneto, one of its elements was placed on a conveyer, and each worker, as it passed, addedanother component to it, the same one each time. Professor David Hounshell of the Universityof Delaware, an expert on industrial development, tells what happened.
"The previous day, workers carrying out the entire process had averaged one assemblyevery 20 minutes. But on that day, on the line, the assemble team averaged one every 13minutes and 10 seconds per person. "
Within a year, the time had been reduced to five minutes. In 1913, Ford went all the way.Hooked together by ropes, partially assembled vehicles were towed (拖,拉) past workers whocompleted them one piece at a time. It hasn't long before Ford was turning out several hundredthousand cars a year, a remarkable achievement then. And so efficient and economical was thisnew system that he cut the price of his cars in half, to $ 260, putting them within reach of allthose who, up until that time, could not afford them. Soon, auto makers the world over copiedhim. In fact, he encouraged them to do so by writing a book about all of his innovations,entitled Today and Tomorrow. The Age of the Automobile has arrived. Today, aided by robotsand other forms of automation (自动化), everything from toasters to perfumes is made onassembly lines.
