单选题. Car crashes are the leading cause of injury and death among U. S. children, and though most of us now think of car seats as standard baby equipment, about half of all children under the age of four who died in vehicle accidents last year were no restrained. It is calculated that only about two-thirds of children aged five to fifteen buckle their seat belts. Moreover, the traffic-safety agency estimates that even among parents who always strap their children in, 85% are not doing it properly. They often don't know where best to place the kids, don't use the proper restraint for their age and weight, or don't install the safety seats properly. Despite the reports about front seats collapsing onto back seats when certain car models get in accidents, the safest place in the car for any child up to the age of 12 is still the back seat. Babies up to 9 kg and one year old should ride in rear-facing infant seats. Never place a child under age 12 in the front seat with a working passenger-side air bag. These devices are discharged at 320 km/h and can be triggered by low-speed fender benders. They have killed 77 kids in the U. S. since 1993. If you must place a child in front, make sure the passenger-side bag is switched off. Children over age one should ride in forward-facing safety seats with a five-point harness system. A child who weighs at least 18 kg or at least I m high can graduate to a booster seat that elevates her so that the standard shoulder and lap belt fits properly.21.

单选题. Baekeland and Hartmann report that the "short sleepers" had been more or less average in their sleep needs until the men were in their teens. But at about age 15 or so, the men voluntarily began cutting down their nightly sleep time because of pressures from school, work, and other activities. These men tended to view their nightly periods of unconsciousness as bothersome interruptions in their daily routines. In general, these "short sleepers" appeared ambitious, active, energetic, cheerful, nonconformist (不动摇) in their opinions, and very sure about their career choices. They often held several jobs at once, or workers full-or part-time while going to school. And many of them had a strong urge to appear "normal" or "acceptable" to their friends and associates. When asked to recall their dreams, the "short sleepers" did poorly. More than this, they seemed to prefer not remembering. In similar fashion, their usual way of dealing with psychological problems was to deny that the problem existed, and then to keep busy in the hope that the trouble would go away. The sleep patterns of the "short sleepers" were similar to, but less extreme than, sleep patterns shown by many mental patients categorized as manic (疯人). The "long sleepers" were quite different indeed. Baekeland and Hartmann report that these young men had been lengthy sleeps since childhood. They seemed to enjoy their sleep, protected it, and were quite concerned when they were occasionally deprived of their desired 9 hours of nightly bed rest. They tended to recall their dreams much better than did the "short sleepers". Many of the "long sleepers" were shy, anxious, introverted (内向), inhibited (压抑), passive, mildly depressed, and unsure of themselves (particularly in social situations). Several openly states that sleep was an escape from their daily problems.1. The report suggests that ______.
