单选题If gender conflicts continue at their current rate, my partner gloomily observed, men may fade into extinction and women will manage fine without them. What with test-tube babies, cloning, a falling birth-rate, and have-it-all career women prevailing like never before, it seems as if old-fashioned, instinct-driven sexual selection was totally out of fashion. But a study from four British universities suggests it is alive and well, and busy shaping the next generation. In spite of emancipation, the feminist movement, gender equality, and consistent efforts to avoid gender-stereotyping, men still prefer to marry women who are not too brainy. In the study a high IQ hampered a woman's chance of getting married, with a 40 percent drop in marital prospects for every 16-point rise. The opposite was true for their male class-mates. Top-earning men were 8 per cent more likely to be married than their low-earning peers. How interesting that we automatically assume that men are put off by cleverness in women. Perhaps the brainy women did not wan to get married. Possibly they could not find men clever enough to satisfy them. But these interpretations hardly merit more than a passing thought because this study simply reinforces what we know to be broadly true: that most women do want a committed partner and that most stable marriages occur in a power relation, with the man being the center. We usually think of competitiveness as a male activity, and so it is mainly, which is all the more reason for it causing stress in a marriage. Our ancestry certainly included a long phase when the males competed for the alpha role, in which the top male took all the advantages and most of the group matings. Most men nurse secret dreams of being "benign" dictators. No man likes his wife to earn more than he does. We see how fragile are the marriages of those in which the female has the whip hand in the shape of fame, success, and wealth. In contrast, marriages where the female status is obviously inferior, including arranged marriages, there is a greater stability. Women have to accept that coming into our own and achieving the full potential of our (seemingly superior) capacity to use education will undoubtedly make us more inaccessible as partners. More choosy, and therefore less successful.

单选题{{B}}Passage Two{{/B}} Genetic engineering holds great potential payoffs for farmers and consumers by making crops resistant to pests, diseases, and even chemicals used to kill surrounding weeds; but new research raises concerns that altering crops to withstand such threats may pose new risks--from none other than the weeds themselves. This is due to the weeds' ability to acquire genes from the neighboring agricultural crops. Researchers found that when a weed cross-breeds with a farm-cultivated relative and thus acquires new genetic traits--possibly including artificial genes engineered to make the crop hardier--the hybrid weed can pass along those traits to future generations. "The result may be very hardy, hard-to-kill weeds," said Allison Snow, a plant ecologist at Ohio State University in Columbus who conducted the experiments over the past six years along with two colleagues. They presented their results last week at the annual meeting of the Ecological Society of America in Madison, Wisconsin. The findings suggest that genetic engineering done with the aim of improving crops--growing the new genetic traits such as resistance to herbicides or pests-- could ultimately have unintended and harmful consequences for the crops if weeds acquire the same trait and use it to out-compete the crops. "Gene movement from crops to their wild relatives is an ongoing process that can be ultimately harmful to crops," said Snow. The results of the experiments challenge a common belief that hybrids gradually die out over several generations, Snow explained. "There has been an assumption that crop genes wouldn't persist in crop-weed hybrids" because hybrids are thought to be less successful at reproducing, she said. However, Snow's research contradicted this assumption: Hybrid wild radishes survived in all six generations that were grown since the study began. Although the genetic traits the scientists monitored were natural and not genetically engineered, the findings nonetheless suggest that artificial improvements introduced into crops through genetic engineering could spread to weeds and become permanent traits of the weed population. So strengthened, the weeds may pose a serious risk to the long-term health of agricultural crops. The danger exists in a number of crop plants--including rice, sunflower, sorghum, squash, and carrots--that are closely related to weeds with which they compete. Snow is concerned that the transfer of genes from crops to related weeds could rapidly render many herbicides (chemicals which kill weeds) ineffectual. That situation, she said, would be much like bacterial diseases acquiring resistance to antibiotics. Because plant hybrids arise in a single generation, however, it could happen much more quickly; "Modern agriculture is heavily dependent on herbicides," she said, "so people will notice when those don't work anymore."
