问题     Believe it or not, optical illusion(错觉)can cut highway crashes. Japan is a case in point. It has reduced automobile crashes on some roads by nearly 75 percent using a simple optical illusion. Bent strips, called chevrons(人字形), painted on the roads make drivers think that they are faster than they really are, and thus drivers slow down.
    Now the American Automobile Association Foundation for Traffic Safety in Washington D.C. is planning to repeat Japan’s success. Starting next year, the foundation will paint chevrons and other patterns of strips on selected roads around the country to test how well the patterns reduce highway crashes.
    Excessive speed plays a major role in as much a one fifth of all fatal traffic accidents, according to the foundation. To help reduce those accidents, the foundation will conduct its tests in areas where speed-related hazards are the greatest curves(弯), exit slopes, traffic circles, and bridges.
    Some studies suggest that straight, horizontal bars(水平障碍物)painted across roads can initially cut the average speed of drivers in half. However, traffic often returns to full speed within months as drivers become used to seeing the painted bars.
    Chevrons, scientists say, not only give drivers the impression that they are driving faster than they really are, but also make a lane appear to be narrower. The result is a longer lasting reduction in highway speed and the number of traffic accidents. [br] On roads painted with chevrons, drivers tend to feel that______.
选项 A、they should avoid speed-related hazards
B、they are driving in the wrong lane
C、they should slow down their speed
D、they are approaching the speed limit
答案 C
解析 本题为事实细节题，提问的是在道路上喷涂人字形会使得驾驶员产生什么样的视觉错觉。根据第一段最后一句话“Bent strips，called chevrons(人字形)，painted on the roadsmake drivers think that they are faster than they really are， and thus drivers slowdown．”可知，会让驾驶员以为自己乍速过快从而减速。所以答案为C)。
