請回答第 47 題至第 50 題:
Physical contact is an important factor in an infant’s overall development. Infants usually satisfy this very basic need
in the course of an ordinary day spent with their parents. The meaningful 47 between the parents and the infants
includes feeding, kissing, bathing, and so forth. 48 , if a baby is neglected or even mistreated by being deprived of a
touch, his or her development will suffer on all levels—physical, intellectual, and emotional. Some children have
49 been known to die from this lack of tactile stimulation; many doctors think that many unexplained “crib deaths” are
directly related to lack of touch and its various consequences. Children given up for adoption at a tender age and placed in
50 run orphanages, children brought up by unaffectionate parents, and children whose parents touch them only to beat
them—all these types of children run the risk of never reaching their potential as fully developed adults.
