21. The Crying GameAll normal human infants cry, although they vary a great deal in how much. A mysterious and still unexplained phenomenon is that crying tends to increase in the first few weeks of life, peak in the second or third month, and then decrease. Some babies in the United States cry so much during the peak period-often in excess of three hours a day-and seem so difficult to soothe that parents come to doubt their nurturing skills or begin to fear that their offspring (子孙后代) is suffering from a painful disease. Some mothers discontinue nursing and switch to bottle-feeding because they believe their breast milk is insufficiently nutritious and that their infants are always hungry. In extreme cases, the crying may provoke physical abuse, sometimes even precipitating (使发生) the infant's death.A look at another culture, the Kung San hunter-gatherers of southern Africa, provides us with an opportunity to see whether care-giving strategies have any effect on infant crying. Both the Kung San and Western infants escalate (使增强) their crying during the early weeks of life, with a similar peak at two or three months. A comparison of Dutch, American, and Kung San infants shows that the number of individual crying episodes are virtually identical. What differs is their length: Kung San infants cry about half as long as Western babies. This implies that care-giving can influence only some aspects of crying, such as duration.What is particularly striking about child-rearing among the Kung San is that infants are in constant contact with a caregiver; they are carried or held most of the time, are usually in an upright position, and are breast-fed about four times an hour for one to two minutes at a time. Furthermore, the mother almost always responds to the smallest cry or fret (烦躁) within ten seconds.I believe that crying was adaptive for our ancestors. As seen in the contemporary Kung San, crying probably elicited a quick response, and thus consisted of frequent but relatively short episodes. This pattern helped keep an adult close by to provide adequate nutrition as well as protection from predators. I have also argued that crying helped an infant forge a strong attachment with the mother and-because new pregnancies are delayed by the prolongation of frequent nursing-secure more of her care-giving resources.In the United States, where the threat of predation has receded (降低) and adequate nutrition is usually available even without breast-feeding, crying may be less adaptive. In any case, care-giving in the United States may be viewed as a cultural experiment in which the infant is relatively more separated-and separable-from the mother, both in terms of frequency of contact and actual distance.The Western strategy is advantageous when the mother's employment outside of the home and away from the baby is necessary to sustain family resources. But the trade-off seems to be an increase in the length of crying bouts.

23.The dog has always been considered man’s best friend. Always noted for being particularly faithful in watching over children, he also has his place by the fireside, in the cow pasture (牧场), on the sheep range, and beside the hunter in forest or the blind. He is easy to train, works hard, and often performs wonderfully. And in the frozen polar regions he was once the principal motive power, before being largely displaced by the plane and helicopter.Because he howls (吼叫) in the presence of approaching death, the dog was once thought to have supernatural powers and believed to be capable of seeing gods and ghosts invisible to people. Actually, the basis for these beliefs lies in the dog’s sensitivity to people’s feelings and his superior hearing ability and sense of smell, which enable him to detect signs hidden from human observation. His record of saving lives is outstanding, for he often gives warnings of fire and other dangers not noticed by his master.The dog’s major contribution, however, has been to medical research. Both his food and his structure are comparable to those of human beings, and so he has been the subject of countless demonstrations and experiments. Open-heart operation has been made possible largely because of the dog. But his sacrifice has repaid his own species as well by safeguarding it from rabies (狂犬病), and other serious diseases.(10分)23.1 Which of the following is TRUE according to the passage?(2分)A. The dog is as faithful as cats in serving humans.B. The dog is much more clever in learning than the horse.C. The dog sometimes behave astonishingly and strangely.D. The dog is less useful in serving humans in the Polar Regions now.
