单选题Observe the dilemma of the fungus: it is a plant, but it possesses no chlorophyl. While all other plants put the sun's energy to work for them combining the nutrients of ground and air into body structure, the chlorophylless fungus must look elsewhere for an energy supply. It finds it in those other plants which, having received their energy free from the sun, relinquish it at some point in their cycle either to other animals (like us humans) or to fungi. In this search for energy the fungus has become the earth' s major source of rot and decay. Wherever you see mold forming on a piece of bread, or a pile of leaves turning to compost, or a blown-down tree becoming pulp on the ground, you are watching a fungus eating. Without fungus action the earth would be piled high with the dead plant life of past centuries. In fact, certain plants which contain resins that are toxic to fungi will last indefinitely. Specimens of the redwood, for instance, can still be found resting on the forest floor centuries after having been blown down.

单选题How"s this for unintended consequences? Some of the biggest beneficiaries (受惠者) of the women"s movement have been married men. According to a new study by the Pew Research Center, married men have a 60% higher average household income than they did in 1970, even adjusted for inflation. Unmarried men, on the other hand, only got a 16% bump. One reason for the rise is that more men are marrying women who make more money than they do, mainly because there are more high-income women to go around. In 1970, just 4% of men at the age of 30 to 44 had wives who brought in more money than they did. By 2007, more than a fifth of men in that age range had wives who out-earned them. Members of this thriving demographic (人口统计学的) are effectively doubling their income or more when they wed, without doubling their costs. Aside from the increase in white-collar women, the other trend summed up by the Pew Research Center is that marriage rates have declined most sharply among the least educated men and women, which helps explain why the average household income figures for married men have pulled even further ahead of those for their single counterparts. More of the least rich are unmarried than before. The study, which drew on household income data from the Decennial Census and the 2007 American Community Survey, showed that the biggest gainers were married college-educated men. The biggest losers were unmarried men who did not complete high school or who only had a high school diploma. After adjusting for inflation, the 2007 unmarried low-income men and women had lower household incomes than their 1970 counterparts. "The steeper decline in marriage among the less educated has contributed to a steeper decline in their income," says one of the study"s authors, D"Vera Cohn. The trend has a dark side, says Dalton Conley, social sciences dean at New York University. "High-income women marrying high-income men is one of the drivers of inequality," he says. "It affects the distribution of income between families." He notes that among college-educated high-income couples, the divorce rate is getting lower, while unmarried low-income men and women tend to partner up and then uncouple more rapidly. "This leads to family instability and a cycle of disadvantage," says Conley.
