单选题{{B}}TEXT B{{/B}} Last summer, some twenty-eight thousand homeless people were offered shelter by the city of New York. Of this number, twelve thousand were children and six thousand were parents living together in families. The average child was six years old, the average parent twenty-seven. A typical homeless family included a mother with two or three children, but in about one-fifth of these families two parents were present. Roughly ten thousand single persons, then, made up the remainder of the population of the city's shelter. These proportions vary somewhat from one area of the nation to another. In all areas, however, families are the fastest-growing sector of the homeless population, and in the Northeast they are by far the largest sector already. In Massachusetts, three-fourths of the homeless now are families with children; in certain parts of Massachusetts--Attleboro and Northhampton, for example--the proportion reaches 90 percent. Two-thirds of the homeless children studied recently in Boston were less than five years old. Of the estimated two to three million homeless people nationwide, about 500,000 are dependent children, according to Robert Hayes, counsel to the National Coalition for the Homeless. Including their parents, at least 750, 000 homeless people in America are family members. What is to be made, then, of the supposition that the homeless are primarily the former residents of mental hospitals, persons who were carelessly released during the 1970s? Many of them are, to be sure. Among the older men and women in the streets and shelters, as many as one-third (some believe as many as one-half) may be chronically disturbed, and a number of these people left mental hospitals during the 1970s. But in a city like New York, where nearly half the homeless are small children with an average of six, to operate on the basis of such a supposition makes no sense. Their parents, with an average age of twenty-seven, are not likely to have been hospitalized in the 1970s, either.

单选题Imagine that the world consists of 20 men and 20 women, all of them heterosexual and in search of a mate. Since the numbers are even, everyone can find a partner. But what happens if you take away one man? You might not think this would make much difference. You would be wrong, argues Tim Harford, a British economist, in a book called The Logic of Life. With 20 women pursuing 19 men, one woman faces the prospect of spinsterhood. So she ups her game. Perhaps she dresses more seductively. Perhaps she makes an extra effort to be obliging. Somehow or other, she "steals" a man from one of her fellow women. That newly single woman then ups her game, too, to steal a man from someone else. A chain reaction ensues. Real life is more complicated, of course, but this simple model illustrates an important truth. In the marriage market, numbers matter. And among African-Americans, the difference is much worse than in Mr. Harford's imaginary example. Between the ages of 20 and 29, one black man in nine is behind bars. For black women of the same age, the figure is about one in 150. For obvious reasons, convicts are excluded from the dating pool. Removing so many men from the marriage market has profound consequences. As imprisonment rates exploded between 1970 and 2007, the proportion of U. S.-born black women aged 30-44 who were married plunged from 62% to 33%. Why this happened is complex and furiously debated. The era of mass imprisonment began as traditional mores were already crumbling, following the sexual revolution of the 1960s and the invention of the contraceptive pill. ① It also coincided with greater opportunities for women in the workplace. These factors must surely have had something to do with the decline of marriage. But jail is a big part of the problem, argue Kerwin Kofi Charles, now at the University of Chicago. They divided America up into geographical and racial " marriage markets", to take account of the fact that most people marry someone of the same race who lives relatively close to them.②, Then, after crunching the census numbers, they found that a one percentage point increase in the male imprisonment rate was associated with a 2.4-point reduction in the proportion of women who ever marry.③ Could it be, however, that mass imprisonment is a symptom of increasing social malfunction, and that it was this social malfunction that caused marriage to wither?④ Probably not. For similar crimes, America imposes much harsher penalties than other rich countries. Mr. Charles and Mr. Luoh controlled for crime rates, as a substitution for social malfunction, and found that it made no difference to their results. They concluded that "higher male imprisonment has lowered the likelihood that women marry...and caused a shift in the gains from marriage away from women and towards men. /
