题文
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 aged fifteen to twenty．Ryan's father, Thomas Didone, is a police captain in Montgomery County, Maryland．He said, "It was an inexperienced, immature driver who felt that he was invincible(不可战胜的), 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 upsetting experiences and tragedy for the rest of the community."
Jim Jennings from the Allstate Insurance Company said "The number one cause of distracted-driving accidents is the mobile phone．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．
Reaching for a cell phone when it's going off, you're nine times more likely to get into an accident than normally driving," The insurance industry recently held a safety event near Washington 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．
Debbie Pickford from the Allstate Insurance Company said, "Teens are especially at risk from distracted driving—and not just because they lack experience on the roads．What we know from research on teen brain development, is that teens don't really have fully developed brains until they are twenty-five years old. You put those two things together and you get a much, much higher risk.”

答案
小题1:A
小题2:B
小题3:D
小题4:B
解析
试题分析: 在美国车祸是青少年的头号杀手，而且大多数的车祸都是由于开车时分心，没有留意路况造成的。在本文中作者通过讲述Ryan Didone的死亡以及保险公司所做的实验说明了开车时打手机或发短信是造成车祸的主要原因，人们应该对此高度注意。
小题1:A 细节理解题。根据文章第三段可知手机是造成分心的头号原因，再由后文中的If you're texting while driving, you are twenty-three times more likely to get into an accident than somebody who isn't可知在四个选项中编辑短信是最可能导致交通意外的，故答案选A。
小题2:B推理判断题。本文主要讲的是开车时玩手机的危害，然后作者在文章倒数二、三段介绍了保险公司所做的安全测试，证明了开车时候用手机的危害，由此判断他们的目的是让人们对分心，注意力不集中的驾驶提起高度注意，故答案选B。
小题3:D推理判断题。本文介绍了开车打手机，发短信的危害。开头提出美国青少年的死亡多数是由于车祸，也就是提出问题；然后进一步分析，并且用做的实验进行证明，即分析问题，由此判断文章接下来要解决问题，也就是要提出解决的方法或者应采取的措施，故答案选D。
小题4:B主旨大意题。本文讲述了绝大多数青少年所遭遇的车祸都是由于开车时打手机，发短信造成的。并且对此进行了详细的介绍，由此判断作者的目的是要提醒人们避免开车时候分神，故B选项内容更能够反应文章中心，答案选B。
