[填空题]Companies are jazzing up plant tours and store visits to build a customer loyalty. Visitors to Ford Motor Co.’s new truck plant are shaken as a multi-ton metal-41 stamping press slams being shut. Heat rains down from welding sparks, followed42 by the cooling mist of a paint shop. At Ford’s historic Rouge manufacturing43 trucks complex Dearborn, Mich. , many tourists will watch the assembly of F-15044 pickup from the safety of a mezzanine with 16 feet above the factory floor. They45 will also get up a much more personal feel for the action through multi-sensory46 special effects spilling out of 360-degree screens in an accompanying video tour.47 The $14 for admission price also buys a history lesson about the 87-year-old48 Rouge property, in where Henry Ford once cranked out the Model A and baffled49 union activists, and a display of Ford vehicles is through the ages. The finishing50 touch: an 80-foot tower from which it’s possible to look out over a 10-acre lawn51 that covers the complex’s "living roof", as well as the surrounding it crab-apple52 orchard, bee-hives, and solar panels. Ford’s fancy $30 million visitor center is the latest example of what experts call "experiential" marketing.

Kin Narita and Gin Kanie, Japanese twins who are national longevity icons, celebrated their 105th birthday last week by planting trees and playing golf for the first time. Kanie suggested that activity might be a key to their long lives. "At this age I walk for two hours each morning for exercise," she said.
