When I was young, every Indian had at least three names during his lifetime. His first name was given to him at birth. It described something that had happened at that time. Each Indian was supposed to keep his birth name until he was old enough to earn money for himself. But his friends would always give him a name of their own. No matter what his parents called him, his childhood friends would use the name they had chosen. The Indian earned his real name when he was old enough for his first fight against the enemy. His life name depended on how he acted during this first battle. When he returned he would be given his tribal name by the chief. If he had done well, he would be given a good name. But if he had done poorly, he might be given a bad name. A man was given many chances to improve his name, however. If in a later battle he was very brave in fighting against the enemy, he was given a better name. Some Indians had as many as twelve names - all good and each better than the last. All names given to one Indian belonged to him for the rest of his life. No one else could use them. Even he himself could not give them away. This was because no man could pass on his name unless the chief and the tribe asked him to do so. According to passage, Indian names were important because they ______. A．described the character of a man B．described the appearance of a man C．were never used by other people D．told us his profession

The charity group Plan International says 600 million Asian children are deprived of one of the seven basic needs used to define poverty, including food, safe water, shelter, health and education. And it says 350 million children, equivalent to the population of the European Union, are deprived of two or more basic needs, classifying them as absolutely poor. The group's executive director, Tom Miller, compares these figures to those of the victims from the earthquake and tsunami that devastated parts of southern Asia eight months ago. "Those numbers are absolutely staggering. The world has focused very much on Asia through the tsunami. But in many ways, what we're talking about is, this is a silent tsunami that is happening every single day." The group, basing its figures on United Nations statistics, says some Asian countries, like China and parts of Southeast Asia, have considerably reduced their numbers of poor children. But it says significant populations of poor people remain in isolated rural areas and among ethnic minorities. According to the news, which of the following is not among the basic needs used to define poverty？ A．food B．health C．education D．freedom

It's known that two influenza viruses can recombine when both are present in an animal at the same time, the result of such recombination is a great variety of strains containing different H and N spikes. This raises the possibility that a human influenza virus can recombine with an influenza virus from a low animal to produce an entirely new spike. Research is underway to determine if that is the way that major new strains come into being, another possibility is that two animal influenza strains may recombine in a pig, for example, to produce a new strain which is transmitted to man. According to the passage, scientists have discovered that influenza viruses ______. A．cause ill health in wild birds B．do not always cause symptoms in birds C．are rarely present in wild birds D．change when transferred from animals to man

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.
