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.

1.Friction is a force which opposes motion. Much of the energy supplied to a complicated machine with many moving parts is wasted in overcoming this opposition. The energy is converted into useless heat. The amount thus lost can be considerably reduced and the life of the machine prolonged by careful lubrication. This reduction improves the efficiency of the machine. Another way in which friction is reduced is to substitute roller or ball bearings for the earlier type of bearing, in which the surfaces in contact move by sliding. Bearings of these later types are used very extensively in many kinds of modern machinery.It must not be assumed, however, that friction is always a disadvantage. In many instances it is highly important. Belts are often used in conveying power from one machine to another. In the absence of friction, this could not be done. The driving wheel would not run the belt, neither would the belt run the wheel to driver. Without friction, then, belted machinery could not be used. Again in the case of all motor vehicles, friction is essential in the operation of the brake. Were there no friction, there could be no brake. But even this illustration does not give an adequate picture of the importance of friction. The vehicle could not even be started if it were not for the friction exerted between the tires and the road. Nails hold in wood, and screws hold in either wood or metal by reason of friction, without which they would be useless. Walking is difficult enough on an icy pavement, but it would be wholly impossible if there were no friction at all between the shoe and the pavement.(5分)1.1 Friction arises when____.(1分)A. an opposing force of motion exists B. the energy is wastedC. everything is motionlessD. a complicated machine is supplied with energy
