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 paasengar-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 1m high can graduate to a booster seat that elevates her so that the standard shoulder and lap belt fits properly.x

阅读理解:阅读下面的短文,根据文章内容从A、B、C三个选项中选出一个最佳选项。
Car crashes are the top killer of American teenagers. Most of the crashes result from distracted driving—not paying attention to the road.
Ryan Didone was a fifteen-year-old passenger in a car that hit a tree. He was one of the nation's more than thirty thousand victims of traffic crashes in 2008. Nearly four thousand deaths, about twelve percent involved drivers age fifteen to twenty.
Ryan's father, Thomas Didone, is a police captain in Marylan. "It was an inexperienced, immature driver driving at night with a carload of kids. He was distracted, he was going too fast, and it ended up causing one death and some seriously injured." He shares the story of his son's death to help educate teens and their families about distracted driving.
Jim Jennings from the Allstate Insurance Company says the number one cause of distracted-driving accidents is the mobile phone. He says talking on the phone or reaching for it is like drinking four beers and driving. "If you're texting while driving, you are twenty-three times more likely to get into an accident than somebody who isn't."
Government and private groups are using public service announcements and events to bring more attention to the problem. For example, the insurance industry recently held a safety event for teen drivers. At first, nineteen-year-old Kevin Schumann easily avoided large, inflatable dolls thrown in front of the car to represent children. He also avoided orange cones representing the edge of the road. Then, as part of the test, he started texting. He hit several cones and at least one doll. "That's what really opened up the experience for me to prove how bad it is to really text and drive."
Debbie Pickford of Allstate Insurance says teens are especially at risk from distracted driving —and not just because they lack experience on the roads. "According to the research, teens don't really have fully developed brains until they’re twenty-five years old. You put those two things together and you get a much,much higher risk." A new law proposes a graduated driver licensing system. Graduated means teenagers start with restrictions like on night driving and numbers of passengers. They could not get a full driver's license until age eighteen.

According to the U. S. National Highway Traffic Safety Administration (NHTSA) , car crashes are the leading cause of death among children between 5 and 14 years of age. Says NHTSA: "【61】50% of children who die in crashes are unrestrained. In addition, 4 out of 5 children are【62】restrained. "
The NHTSA offers a number of safety【63】and cautions for those who are accompanied by children while driving. 【64】laws vary from country to country and even from state to state, these guidelines may serve as food for【65】to many parents and guardians of children.
The safest place for all children is in the back seat. Infants should be placed in a rear-facing child safety seat in the baekseat of the car. A child【66】a year old and weighing at least 20 pounds may be placed in a forward-facing seat. At 40 pounds, the child can use a "booster seat(儿童案例椅) ",【67】is secured by one of the car's lap and shoulder belts. At approximately 80 pounds and a【68】of about four feet nine inches, the child may begin using an adult safety strap.
Children should not sit in the front passenger seat【69】they are at least 13 years of age. Front- passenger air bags can cause serious【70】to younger children and babies.
When a booster seat is used, a lap belt alone will not provide【71】protection if the booster seat does not have a【72】.
Do not think that a shoulder belt alone will protect a small child; in the【73】of a crash, the belt may【74】the neck of the child, causing serious injury or even death.

Sleepy Students Perform. Worse
A Staying up an hour or two past bedtime makes it far harder for kids to learn, say scientists who deprived youngsters of sleep and tested whether their teachers could tell the difference. They could. If parents want their children to thrive academically, "Getting them to sleep on time is as important as getting them to school on time," said psychologist Gahan Fallone, who conducted the research at Brown Medical School.
B The study, unveiled Thursday at an American Medical Association science writers meeting, was conducted on healthy children who had no evidence of sleep--or learning-related disorders. Difficulty paying attention was among the problems the sleepy youngsters faced—raising the question of whether sleep deprivation could prove even worse for people with attention deficit hyperactivity disorder, or ADHD. Fallone now is studying that question, and suspects that sleep problems "could hit children with ADHD as a double whammy."
C Sleep experts have long warned that Americans of all ages don't get enough shuteye. Sleep is important for health, bringing a range of benefits that, as Shakespeare put it, "knits up the raveled sleave of care." Not getting enough is linked to a host of problems, from car crashes as drivers doze off to crippled memory and inhibited creativity. Exactly how much sleep correlates with school performance is hard to prove. So Brown researchers set out to test whether teachers could detect problems with attention and learning when children stayed up late—even if the teachers had no idea how much sleep their students actually got.
D They recruited seventy-four 6- to 12-year-olds from Rhode Island and southern Massachusetts for the three-week study. For one week, the youngsters went to bed and woke up at their usual times. They already were fairly good sleepers, getting nine to 9.5 hours of sleep a night. Another week, they were assigned to spend no fewer than ten hours in bed a night. The other week, they were kept up later than usual: First- and second-graders were in bed no more than eight hours and the older children no more than 6. 5 hours. In addition to parents' reports, the youngsters wore motion-detecting wrist monitors to ensure compliance.
E Teachers weren't told how much the children slept or which week they stayed up late, but rated the students on a variety of performance measures each week. The teachers reported significantly more academic problems during the week of sleep deprivation, the study, which will be published in the journal Sleep in December, concluded. Students who got eight hours of sleep or less a night were more forgetful, had the most trouble learning new lessons, and had the most problems paying attention, reported Fallone, now at the Forest Institute of Professional Psychology.
F Sleep has long been a concern of educators. Potter-Burns Elementary School sends notes to parents reminding them to make sure students get enough sleep prior to the school's yearly achievement testing. Another school considers it important enough to include in the school's monthly newsletters. Definitely there is an impact on students' performance if they come to school tired. However, the findings may change physician practice, said Dr. Regina Benjamin, a family physician in Bayou La Batre, who reviewed the data at the Thursday's AMA meeting. "I don't ask about sleep" when evaluating academically struggling students, she noted. "I'm going to start."
G So how much sleep do kids need? Recommended amounts range from about ten to eleven hours a night for young elementary students to 8.5 hours for teens. Fallone insists that his own second-grader get ten hours a night, even when it meant dropping soccer the season that practice didn't start until 7:30—too late for her to fit in dinner and time to wind down before she needed to be snoozing. "It's tough," he acknowledged, but "parents must believe in the importa
