An Observation and an ExplanationIt is worth looking at one or two aspects of the way a mother behaves towards her baby. The usual fondling, cuddling and cleaning require little comment, but the position in which she holds the baby against her body when resting is rather revealing. Careful studi es have shown the fact that 80 percent of mothers hold their infants in their left arms, ho lding them against the left side of their bodies. If asked to explain the significance of thi s preference most people reply that it is obviously the result of the predominance of right -handedness in the population. By holding the babies in their left arms, the mothers keep their dominant arm free for manipulations. But a detailed analysis shows that this is not t he casE True, there is a slight difference between right-handed and left-handed females。

b ut not enough to provide adequate explanation. It emerges that 83 percent of right-handed mothers hold the baby on the left side, but so do 78 percent of left-handed mothers. In other words, only 22 percent of the left-handed mothers have their dominant hands free fo r actions. Clearly there must be some other, less obvious explanation.The only other clue comes from the fact that the heart is on the side of the mother’ s body. Could it be that the sound of her heartbeat is the vital factor? And in what way? Thinking along these lines it was argued that perhaps during its existence inside the bod y of the mother the unborn baby get used to the sound of the heart beat. If this is so, th en the re-discovery of this familiar sound after birth might have a claiming effect on the infant, especially as it has just been born into a strange and frighteningly new worlD if t his is so then the mother would, somehow, soon arrive at the discovery that her baby is more at peace if held on the left against her heart than on the right.16 We can learn a lot by observing the position in which a mother holds her babya gainst her body.A RightB WrongC Not mentioned17 Most left-handed women feel comfortable by holding their babies in their left arm and keep the right arm free.A RightB WrongC Not mentioned18 The number of right-handed mothers who hold the baby on the left side exceeds t hat of left-handed ones by 22%.A RightB WrongC Not mentioned19 The fact that most left-handed mothers hold the baby on their left side renders th e first explanation unsustainable.A RightB WrongC Not mentioned20 The fact that the heart is on the left side of the mothers body provides the most convincing explanation of all.A RightB WrongC Not mentioned21 A baby held in the right arm of its mother can be easily frightened.A RightB WrongC Not mentioned22 The writers explanation of the phenomenon is supported by the fact that babies te nd to be more peaceful if held in their mothers left arms than in the right arms.A RightB WrongC Not mentioned三、概括大意与完成句子。
