There are two primary causes of traffic accidents, those that are caused by the driver and those that are environmental and outside the driver's control. {{U}} {{U}} 1 {{/U}} {{/U}}environmental issues like weather or poor road maintenance may cause an accident, statistically these are far less likely to do so. Driver distractions prove to be the main cause of accidents. The most {{U}} {{U}} 2 {{/U}} {{/U}}distractions are looking at traffic, crashes and roadside incidents. While it is widely believed that cell phones are a greater cause, cell phones only {{U}} {{U}} 3 {{/U}} {{/U}}sixth on the list. {{U}} {{U}} 4 {{/U}} {{/U}}, laws to limit cell phone use while driving do not decrease accidents. Hands-free phones are {{U}} {{U}} 5 {{/U}} {{/U}}than hand-held devices.
Alcohol was a factor in at least 41 percent of all fatal crashes. Alcohol {{U}} {{U}} 6 {{/U}} {{/U}}affects vision, reaction time and attention of the driver, and decreases overall driving performance. Fatigue {{U}} {{U}} 7 {{/U}} {{/U}}100,000 vehicle crashes per year, killing {{U}} {{U}} 8 {{/U}} {{/U}}1,500 people and injuring 71,000 people. Accidents caused by fatigue are particularly {{U}} {{U}} 9 {{/U}} {{/U}}for truck drivers and others taking long-haul driving trips. Speeding is another major cause of traffic accidents, particularly for younger or newer drivers. Teens are more likely to speed, and among male drivers aged 15 to 20 who were {{U}} {{U}} 10 {{/U}} {{/U}}a fatal crash in 2005, 37 percent were speeding at the time of the crash.
单选题
  • A. Because
  • B. If
  • C. While
  • D. However
【正确答案】 C
【答案解析】选择此题答案时要考虑该句中主句与从句的意义联系。从句讲环境因素可能引发事故，而主句说明根据统计数字，环境因素引发事故的概率要小得多。两句有转折关系，故选while。
单选题
  • A. disruptive
  • B. constructive
  • C. instructive
  • D. descriptive
【正确答案】 A
【答案解析】文章第四句空白处之后的词是distractions(走神，精力不集中，使人分散精力的因素)。修饰该词的形容词不可能是constructive(建设性的)或instructive(有指导作用的，有启发作用的)，而descriptive的含义是“描述的”，所以只剩下disruptive，其意义是“使……无法正常运行的”或“有破坏作用的”。
单选题
  • A. come across
  • B. come on
  • C. come about
  • D. come in
【正确答案】 D
【答案解析】come across：偶然遇到；come on：快点，快说；come about：发生；come in：比赛中获得……名次。
单选题
  • A. Even so
  • B. In fact
  • C. By contrast
  • D. For example
【正确答案】 B
【答案解析】此选项要考虑空白处前后两句的意义关系。前面讲的是司机使用手机引发事故的概率名列第六，后面讲限制司机使用手机的法律并不能减少事故。两句没有转折关系，因此排除了even so(即使这样)。两句都在谈手机，不是对比关系，选择by contrast不合适，而for example是“举例说明”。in fact常用于表示“进一步讲”。
单选题
  • A. no longer safe
  • B. not so safe
  • C. more safer
  • D. no more safe
【正确答案】 D
【答案解析】空白处后面是than，表明该句可能涉及比较级，因此排除了no longer safe，而not so safe和more safer不符合正确的语法结构。no more safe相当于no safer，可以与than连用，含义是“与……一样不安全”。例如：You can store thousands of books in a container no bigger than a washing machine．(像洗衣机一样小的容器中)
单选题
  • A. adversely
  • B. favorably
  • C. scarcely
  • D. affectionately
【正确答案】 A
【答案解析】众所周知，饮酒影响视力、反应时间和注意力。这样的影响都是“负面影响”，所以是adversely。favorably：有利地；scarcely：很少；affectionately：充满爱地。
单选题
  • A. stands for
  • B. runs for

单选题
  • A. as much as
  • B. as long as
  • C. as soon as
  • D. as many as
【正确答案】 D
【答案解析】英语中常用as...as表示强调，有“……达”的含义，如a couple that had as many as ten kids。因为后面的名词people是可数的，所以选as many as。
