Global Reading Detailed Reading After Reading Supplementary Reading Detailed Reading Before Reading Unit 2 Smart Cars A century later, with automakers and auto buyers expanding globally, automaking became the world’s largest manufacturing activity, with more than 53 million new vehicles built each year worldwide. Automobile manufacturers are among the largest companies in the world. These corporations are often multinational. These companies often share parts, or use parts made in foreign factories. The U.S. automobile industry produced 16.8 million vehicles in 1999. The three major automobile manufacturers in the United States—General Motors Corporation, Ford Motor Company, and Daimler Chrysler AG—provide three fourths of the industry’s total direct employment in the United States

GPS provides users with accurate information about their position and velocity, as well as the time, anywhere in the world and in all weather conditions. GPS determines location by computing the difference between the time that a signal is sent and the time it is received. GPS satellites carry atomic clocks that provide extremely accurate time. As of March 1994, 24 GPS satellites were in operation. Replenishment (补给) satellites are ready for launch, and
