Dr. J. Robinson found out about the phenomenon of self-controlled pain almost by accident. He was studying the effects of analgesics used to control pain during childbirth and as part of the experiment made it possible for women having their child to press a button which gave an automatic injection—instead of having all injections made by the doctor. Afterwards these women did not say that they had less pain than other women in childbirth, but they did use considerable less of the drug. J. Atkins, a dental surgeon, has observed a similar phenomenon. As part of their efforts to make dentistry painless, Atkins and researchers at Aston University in Birmingham offered patients a switch they could flip to turn off the dentist's drill whenever they chose. But, after trying the switch on 50 patients Atkins gave up; none of the patients had ever flipped the switch. Perhaps the extra endurance was because the Aston team also use other methods to make dentistry painless. Apparently few other dentists are so considerate. The end result, according to the Birmingham survey, is that British people avoid going to the dentist, with the consequence that almost 30% of people in England and Wales have lost all their teeth, and more than seven out of ten have lost at least six teeth. Less than half of the public pay regular visits to the dentist. To find out why, Atkins and psychologist Cumberbatch interviewed a sample of patients attending a dental hospital. The most common reason people gave for not having dental check-ups were fear and pain. By using a little care and taking time to explain what will happen, Atkins feels, dentists could overcome these fears. There are techniques for giving injections without pain, and a "calm unhurried approach" to drilling can make that painless, too. Sadly, few dentists seem to take much trouble with their patients. "I am not nervous when I go to the dentist, and I do not have any pronounced sympathy for those who are, " said one dentist. "I tend to take the point of view that they are being unreasonable at my expense." The passage most possibly comes from______. A．a medical textbook B．a psychology textbook C．a popular magazine D．a serious magazine

Other members of the autoworker’s family, however, might be less inclined to trade the present for the past. His retired parents would certainly have had less economic security back then. Throughout much of the 1960s, more than a quarter of men and women age 65 and older lived below the poverty level, compared to less than 10 percent in 2010. In most states, his wife could not have taken out a loan or a credit card in her own name. In 42 states, a homemaker had no legal claim on the earnings of her husband. And nowhere did a wife have legal protection against family violence. Most black workers would not want to return to a time when, on average, they earned 40 percent less than their white counterparts (职位相对的人), while racially restrictive agreements largely prevented them from buying into the suburban neighborhoods being built for white working-class families. Today, new problems have emerged in the process of resolving old ones, but the solution is not to go back to the past. Some people may long for an era when divorce was still hard to come by. The spread of no-fault divorce has reduced the bargaining power of whichever spouse is more interested in continuing the relationship. And the breakup of such marriages has caused pain for many families. The growing diversity of family life comes with new possibilities as well as new challenges. According to a recent poll, more than 80 percent of Americans believe that their current family is as close as the one in which they grew up, or closer. Finding ways to improve the lives of the remaining 20 percent seems more realistic than trying to restore an imaginary golden age. 61. What do we learn about American autoworkers in 1950？ A) They had less job security than they do today. B) It was not too difficult for them to buy a house. C) Their earnings were worth twice as much as today. D) They were better off than workers in other industries. 62. What does the author say about retired people today？ A) They invariably long to return to the golden past. B) They do not depend so much on social welfare. C) They feel more secure economically than in the past. D) They are usually unwilling to live with their children. 63. Why couldn’t black workers buy a house in a white suburban neighborhood？ A) They lacked the means of transportation. B) They were subjected to racial inequality. C) They were afraid to break the law. D) They were too poor to afford it. 64. What is the result of no-fault divorce？ A) Divorce is easier to obtain. B) Domestic violence is lessened. C) It causes little pain to either side. D) It contributes to social unrest. 65. What does the author suggest society do？ A) Get prepared to face any new challenges. B) Try to better the current social security net. C) Narrow the gap between blacks and whites. D) Improve the lives of families with problems.
