22.Fifty volunteers were alphabetically divided into two equal groups, Group A to participate in a 7 week exercise program, and Group B to avoid deliberate exercise of any sort during those 7 weeks. On the day before the exercise program began, all 50 men participated in a step-test. This consisted of stepping up and down on a 16-inch bench at 30 steps a minute for 5 minutes. One minute after completion of the step-test, the pulse rate of each subject was taken had recorded. This served as the pretest for the experiment. For the next 7 weeks, subjects in the experimental group (Group A) rode an Exercycle (a motor-driven bicycle-type exercise machine) for 15 minutes each day. The exercise schedule called for riders to ride relaxed during the first day's ride, merely holding on to the handle bars and foot pedals as the machine moved. Then, for the next 3 days, they rode relaxed for 50 seconds of each minute, and pushed, pulled, and pedaled actively for 10 seconds of each minute. The ratio of active riding was increased every few days, so that by the third week it was half of each minute, and by the seventh week the riders were performing 15 solid minutes of active riding.At the end of the 7 weeks, the step-test was again given to both groups of subjects, and their pulses were taken. The post-exercise pulse rates of subjects in the experimental group were found to have decreased an average of 30 heart beats per minute, with the lowest decrease 28 and the highest decrease 46. The pulse rates of subjects in the control group remained the same or changed no more than 4 beats, with an average difference between the initial and final tests of zero.22.1 How many people were in each group?____A. 100.

24. Today we remember a man who was considered one of the best teachers in the United States. Jaime Alfonso Escalante was born in 1930 in La Paz, Bolivia. Both his parents were teachers. He taught math and science in his home country for twelve years. In the 1960s, Jaime Escalante and his wife Fabiola came to the United States. During the next several years, he learned to speak English and repeated his college education and teacher training. In 1974, Mr. Escalante was hired at GarfieldHigh School to teach mathematics. The school was in a poor area of Los Angeles, California. Many of the students had serious problems with illegal drugs, gangs and violence. Many were the worst students at the school and thought to be “unteachable”. But Mr. Escalante pushed the group to work hard. He told them basic math was too easy and that they had the ability to do harder work. He told his students that he believed in them, but they must have the desire to be successful. Jaime Escalante started an advanced math program with a small group of students. Advanced Placement is a program of college-level classes and tests. In 1982, 18 of his students took the Advanced Placement test in calculus. They all passed. Officials at the testing company suspected the students of cheating. Mr. Escalante protested. He said the students were being rejected because they were Hispanic and from a poor school. He urged his students to take the test again. Twelve of the students repeated the test. And again, all of them passed. Five earned top scores. Mr. Escalante's students went on to become engineers, scientists and university professors. The advanced math program at Garfield became extremely successful over the next several years. Jaime Escalante received many teaching awards including the Presidential Medal of Excellence in Education. A movie about his success, “Stand and Deliver”, was released in nineteen eighty-eight. It influenced other teachers to use his methods.(10分)24.1 What did Mr. Escalante do after he came to the US?(2分)A. He taught math and science in a local school.B. He went to a college to learn calculus.C. He learned to speak English and got trained on teaching. D. He started an advanced math program in a college.
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.

Their parents lack nurturing skill.C. The reason is still unknown.D. Their parents abuse the infants physically.
