[单项选择]Children in the United States are exposed to many influences other than that of their families. Television is the most significant of these influences, because the habit of watching television usually begins before children start attending school. And, by the time that the average child finishes high school, he or she will have spent 18,000 hours in front of a television set as opposed to 12,000 hours in a classroom.

The gift of being able to describe a face accurately is a rare one, as every experienced police officer knows to his cost. As the Lancet put it recently: " When we try to describe faces precisely words fail us and we resort to identikit(拼脸型图)procedures."
Yet, according to one authority on the subject, we can each probably recognize more than 1,000 faces, the majority of which differ in fine details. This, when one comes to think of it, is a tremendous feat, though, curiously enough, relatively little attention has been devoted to the fundamental problems of how and why we acquire this gift for recognizing and remembering faces. Is it an inborn property of our brains, or an acquired one As so often happens, the experts tend to differ.
Thus, some argue that it is inborn, and that there are "special characteristics about the brain’s ability to distinguish faces". In support of this they note how much better we are at recognizing a face after
