单选题. It is generally acknowledged that young people from poorer socioeconomic backgrounds tend to do less well in our education system. That is observed not just in New Zealand, but also in Australia, Britain and America. In an attempt to overcome that educational underachievement, a nationwide program called "Headstart" was launched in the United States in 1965. A lot of money was poured into it. It took children into preschool institutions at the age of three and was supposed to help the children of poorer families succeed in school. Despite substantial funding, results have been disappointing. It is thought that there are two explanations for this. First, the program began too late. Many children who entered it at the age of three were already behind their peers in language and measurable intelligence. Second, the parents were not involved. At the end of each day, "Headstart" children returned to the same disadvantaged home environment. As a result of the growing research evidence of the importance of the first three years of a child's life and the disappointing results from "Headstart", a pilot program was launched in Missouri in the US that focused on parents as the child's first teachers. The "Missouri" program was predicated on research showing that working with the family, rather than bypassing the parents, is the most effective way of helping children get off to the best possible start in life. The four years pilot study included 380 families who were about to have their first child and who represented a cross section of socioeconomic status, age and family configurations (结构). They included single parent and two parent families, families in which both parents worked, and families with either the mother or father at home. The program involved trained parent educators visiting the parents' home and working with the parent, or parents, and the child. Information on child development, and guidance on things to look for and expect as the child grows were provided, plus guidance in fostering the child's intellectual, language, social and motor skill development. Periodic checkups of the child's educational and sensory development (hearing and vision) were made to detect possible handicaps that interfere with growth and development. Medical problems were referred to professionals. At the age of three, the children who had been involved in the "Missouri" program were evaluated alongside a cross section of children selected from the same range of socioeconomic backgrounds and family situations, and also a random sample of children that age. The results were phenomenal. By the age of three, the children in the program were significantly more advanced in language development than their peers, had made greater strides in problem solving and other intellectual skills, and were further along in social development. In fact, the average child on the program was performing at the level of the top 15 to 20 percent of their peers in such things as auditory comprehension, verbal ability and language ability.1. Who has more opportunity to be admitted to involve in "Headstart" programme?

单选题. Birds that are literally half asleep—with one brain hemisphere alert and the other sleeping—control which side of the brain remains awake, according to a new study of sleeping ducks. Earlier studies have documented half brain sleep in a wide range of birds. The brain hemispheres take turns sinking into the sleep stage characterized by slow brain waves. The eye controlled by the sleeping hemisphere keeps shut, while the wakeful hemisphere's eye stays open and alert. Birds also can sleep with both hemispheres resting at once. Decades of studies of bird flocks led researchers to predict extra alertness in the more vulnerable, end-of-the-row sleepers. Sure enough, the end birds tended to watch carefully on the side away from their companions. Ducks in the inner spots showed no preference for gaze direction. Also, birds dozing at the end of the line resorted to single hemisphere sleep, rather than total relaxation, more often than inner ducks did. Rotating 16 birds through the positions in a four duck row, the researchers found outer birds half asleep during some 32 percent of dozing time versus about 12 percent for birds in internal spots. "We believe this is the first evidence for an animal behaviorally controlling sleep and wakefulness simultaneously in different regions of the brain," the researchers say. The results provide the best evidence for a long standing supposition that single hemisphere sleep evolved as creatures scanned for enemies. The preference for opening an eye on the lookout side could be widespread, he predicts. He's seen it in a pair of birds dozing side by side in the zoo and in a single pet bird sleeping by a mirror. The mirror side eye closed as if the reflection were a companion and the other eye stayed open. Useful as half sleeping might be, it's only been found in birds and such water mammals(哺乳动物) as dolphins, whales, and seals. Perhaps keeping one side of the brain awake allows a sleeping animal to surface occasionally to avoid drowning. Studies of birds may offer unique insights into sleep. Jerome M. Siegel of the UCLA says he wonders if birds' half brain sleep "is just the tip of the iceberg (冰山)." He speculates that more examples may turn up when we take a closer look at other species.1. A new study on birds' sleep has revealed that ______.
