单选题 Few people doubt the fundamental importance of mothers in child-rearing, but what do fathers do? Much of what they contribute is simply the result of being a second adult in the home. Bringing up children is demanding, stressful and exhausting. Two adults can support and make up for each other's deficiencies and build on each other's strengths. Fathers also bring an array of unique qualities. Some are familiar: protector and role model. Teenage boys without fathers are notoriously prone to trouble. The pathway to adulthood for daughters is somewhat easier, but they must still learn from their fathers, in ways they cannot from their mothers, how to relate to men. They learn from their fathers about heterosexual trust, intimacy and difference. They learn to appreciate their own femininity from the one male who is most special in their lives. Most important, through loving and being loved by their fathers, they learn that they are love-worthy. Current research gives much deeper—and more surprising—insight into the father's role in child-rearing. One significantly overlooked dimension of fathering is play. From their children's birth through adolescence, fathers tend to emphasize play more than caretaking. The father's style of play is likely to be both physically stimulating and exciting. With older children it involves more teamwork, requiring competitive testing of physical and mental skills. It frequently resembles a teaching relationship: come on, let me show you how. Mothers play more at the child's level. They seem willing to let the child direct play. Kids, at least in the early years, seem to prefer to play with daddy. In one study of 2.5-year-olds who were given a choice, more than two-thirds chose to play with their father. The way fathers play has effects on everything from the management of emotions to intelligence and academic achievement. It is particularly important in promoting self-control. According to one expert, "children who roughhouse with their fathers quickly learn that biting, kicking and other forms of physical violence are not acceptable." They learn when to "shut it down." At play and in other realms, fathers tend to stress competition, challenge, initiative, risk-taking and independence. Mothers, as caretakers, stress emotional security and personal safety. On the playground fathers often try to get the child to swing even higher, while mothers are cautious, worrying about an accident. We know, too, that fathers' involvement seems to be linked to improved verbal and problem-solving skills and higher academic achievement. Several studies found that along with paternal strictness, the amount of time fathers spent reading with them was a strong predictor of their daughters' verbal ability. For sons the results have been equally striking. Studies uncovered a strong relationship between fathers' involvement and the mathematical abilities of their sons. Other studies found a relationship between paternal nurturing and boys' verbal intelligence.

单选题{{B}}Passage Two{{/B}} There have been several claims to have cloned humans over the past few years. Most have been bogus. But the announcement made this week by Woo Suk Hwang, of Seoul National Uni- versity in South Korea, and his colleagues, is serious. It is the first to achieve the accolade of publication in a peer-reviewed scientific journal. Dr. Hwang's work appears in Science. The terminology of human development has become slippery over the past few years, in the hands of both "life-begins-at-conception" propagandists who want to stop this sort of research, and publicity-seeking scientists who have claimed more than they have really achieved．What Dr. Hwang and his team have created is not what developmental biologists would normally refer to as an embryo. But it is a genuine scientific advance. South Korea's researchers have taken egg cells from volunteer women, removed the nuclei from those cells (which contain only half of the genetic complement required to make a human being, since the other half is provided by the sperm), and replaced each nucleus with one taken from one of the volunteer's body ceils (which contains a full genetic complement). Given a suitable chemical kick-start, such re-nucleated cells will begin dividing as though they were eggs that had been fertilised in the more traditional manner. Since they have all of the mother's genes, they count as clones. Then the team cultured the dividing eggs until they had formed structures called blastocysts, with a few dozen cells each. This is the significant advance. At this stage the structure, though still just a featureless ball of cells, has started to differentiate into the body's three basic cell types (known as endoderm, mesoderm and ectoderm). The researchers were able to extract cells from some of their blastocysts, and grow tissues containing all three cell types. These are so-called stem cells, which can be directed to form a wide variety of the specialised cells from which organs are built. That, not the creation of new human beings, is the stated reason for this sort of research, since specialised ceils made this way might be used to replace the cells lost in diseases such as Parkinson's and type-I diabetes. This process is known as therapeutic cloning. No doubt Dr Hwang's scientific success will sharpen the debate between those who see therapeutic cloning as a potential force for good, and those who see it as a step on the road to a cloned human being. The former have been queuing up to praise the scientist's work. It is "a major med- ical milestone" that could help spur a "revolution", said Robert Lanza, a cloning expert. But opponents of therapeutic cloning should not worry too much yet. The road from a blast cyst to a baby is a long and complex one. Nevertheless, the South Korean breakthrough makes it more urgent than ever that legislation be passed differentiating clearly between therapeutic and reproductive cloning—permitting the former and prohibiting the latter.

单选题As with any work of art, the merit of Chapman Kelley's "Wildflower Works I" was in the eye of the beholder. Kelley, who normally works with paint and canvas, considered the twin oval gardens planted in 1984 at Daley Bicentennial Park his most important piece. The Chicago Park District considered it a patch of raggedy vegetation on public property that could be dug up and replanted at will like the flower boxes along Michigan Avenue. And that's what happened in June 2004, when the district decided to create a more orderly vista for pedestrians crossing from Millennium Park via the new Frank Gehry footbridge. If you're looking for evidence that the rubes who run the Park District don't know art when they see it, all you have to do is visit what's left of Kelley's masterpiece. The exuberant 1.5-acre tangle of leggy wildflowers is now confined to a tidy rectangle, restrained on all sides by a knee-high hedge and surrounded by a closely cropped lawn. White hydrangeas and pink shrub roses complete the look. We don't know who's responsible for the redesign, but we'll bet the carpet in his home doesn't go with the furniture. Still, you'd think the Park District was within its rights to plow under the prairie. Wrong. Kelley just won at lawsuit in which he argued that the garden was public art and therefore protected by the federal Visual Artists Rights Act. Under that law, the district should have given him 90 days'notice that it intended to mess with his artwork instead of rushing headlong into the demolition, a la Meigs Field. That way Kelley could have mounted a legal challenge, or at least removed the plants. Park District officials said they never considered the garden a work of art, even though it was installed by an established artist and not, say, Joe's Sod and Landscaping. We can understand their confusion. Just recently, we figured out that the caged greenery directly south of Pritzker Pavilion is supposed to be an architectural statement and not a Christmas tree lot. All that's left is for the district to compensate Kelley for his loss. Whatever price the parties settle on, let's hope the agreement also provides for the removal of the rest of "Wildflower Works I". If it wasn't an eyesore before—and plenty of people thought it was—it sure is now.
