传染病
传染病（Infectious Diseases）是由各种病原体引起的能在人与人、动物与动物或人与动物之间相互传播的一类疾病。病原体中大部分是微生物，小部分为寄生虫，寄生虫引起者又称寄生虫病。有些传染病，防疫部门必须及时掌握其发病情况，及时采取对策，因此发现后应按规定时间及时向当地防疫部门报告，称为法定传染病。中国的法定传染病有甲、乙、丙3类，共40种。传染病是一种能够在人与人之间或人与动物之间相互传播并广泛流行的疾病，经过各种途径传染给另一个人或物种的感染病。通常这种疾病可借由直接接触已感染的个体、感染者的体液及排泄物、感染者所污染到的物体，可以通过空气传播、水源传播、食物传播、接触传播、土壤传播、垂直传播（母婴传播）、体液传播、粪口传播等。

Passage 1Every day 25 million U.S. children ride school buses. The safety record for these buses is much better than for passenger cars; but nevertheless, about 10 children are killed each year riding on large school buses, and nearly four times that number are killed outside buses in the loading zones. By and large, however, the nation's school children are transported to and from school safety.Even though the number of school bus casualties is not large, the safety of children is always of intense public concern. While everyone wants to see children transported safely, people are divided about what needs to be done particularly whether seat belts should be mandatory.Proponents of seat belts on school buses-many of them parents and medical organizations argue that seat belts are necessary not only to reduce fatality and injury, but also to teach children lessons about the importance of using them routinely in any moving vehicle. A side benefit, they point out, is those seats belts help keep children in their seats, away from the bus driver.Opponents of seat belt installation suggest that children are already well protected by the school buses that adhere to the Nation Highway Traffic Safety Administrations(NHTSA) safety requirements set in 1977. They also believe that many children won't wear seat belts anyway and that may damage the belts or use them as weapons to hurt other children.A new Research Council report on school bus safety suggests that there are alternate safety devices and procedures that may be more effective and less expensive. For example, the study committee suggested that raising seat backs four inches may have the same safety effectiveness as seat belts.The report sponsored by the Department of Transportation at the request of Congress, reviews seat belts extensively while taking a broader look at safety in and around school buses.According to the passage, the "school bus" is________.
