[单项选择]
The twenty-third Olympic Games, held in Los Angeles, were very much a contest of mind, muscle, and athletic determination. However, high technology, especially in the computer field, played an increasing role in both the staging of the event and the race for the gold. Computers were used to keep track of schedules, accounts, transportation, and ticketing for more than 43,000 Olympic employees and volunteers.

During the first two months of a baby’’s life, the stimulus that produces a smile is a pair of eyes. The eyes need not be real: a mask with two dots will produce a smile. Significantly, a real human face with eyes covered will not motivate a smile, nor will be the sight of only one eye when the face is presented in profile. This attraction to eyes as opposed to the nose or mouth continues as the baby matures. In one study, when American four-year-old were asked to draw people, 75 percent of them drew people with mouths, but 99 percent of them drew people with eyes. In Japan, however, where babies are carried on their mother’’s back, infants do not acquire as much attachment to eyes as they do in other culture. As a result, Japanese adults make little use of the face either to encode or decode meaning. In fact, Argyle reveals that the "proper place to
A. not to wear dark spectacles
B. not to glance away from each other
C. not to make any interruptions
D. not to make unpredictable pauses
