问题     More than 30 000 drivers and front seat passengers are killed or seriously injured each year. At a speed of only 30 miles per hour it is the same as falling from a third floor window. Wearing a seat belt saves lives; it reduces your chance of death or serious injury by more than half.
    Therefore drivers or front seat passengers over 14 in most vehicles must wear a seat belt. If you do not, you could be fined up to £50. It will not be up to the drivers to make sure you wear your belt. But it will be the driver’s responsibility to make sure that children under 14 do not ride in the front unless they are wearing a seat belt of some kind.
    However, you do not have to wear a seat belt if you are reversing your vehicle; or you are making a local delivery or collecting using a special vehicle; or if you have a valid medical certificate which excuses you from wearing it. Make sure these circumstances apply to you before you decide not to wear your seat belt. Remember you may be taken to court for not doing so, and you may be fined if you cannot prove to the court that you have been excused from wearing it.
Wearing a seat belt in a vehicle______.

选项 A、reduces road accidents by more than half
B、saves lives while driving at a speed up to 30 miles per hour
C、reduces the death rate in traffic accidents
D、saves more than 15 000 lives each year

答案C

解析 本题是一道具体细节题,主要考查学生是否读懂了第一段的内容。文章第一段最后一句话指出,系安全带能够挽救性命,使死亡率或严重受伤率减少一半以上。由此我们可以看出,驾驶员和前排乘客系上安全带在发生交通事故时可以大幅度地减少伤亡,即选项C是正确的。系不系上安全带并不能减少交通事故,也不能保证汽车时速30英里时不发生交通事故,从而拯救性命。文章只是提到驾驶员和前排乘客每年死伤人数超过3万,并未说系上安全带每年就可以挽救1.5万多人的生命。因此,选项A、B和D都是错误的。
