问题 Driven to Distraction
Joe Coyne slides into the driver’s seat, stars up the car and heads to town. The empty stretch of interstate gives way to urban congestion, and Coyne hits the brake as a pedestrian suddenly crosses the street in front of him.
But even if he hadn’t stopped in time, the woman would have been safe. She isn’t real. Neither is the town. And Coyne isn’t really driving. Coyne is demonstrating a computerized driving simulator that is helping researchers at Old Dominion University (ODU) examine how in-vehicle guidance systems affect the person behind the wheel.
The researchers want to know if such systems, which give audible or written directions, are too distracting—or whether any distractions are offset by the benefits drivers get from having help finding their way in unfamiliar locations.
"We’re looking at the performance and mental workload of drivers," said Caryl Baldwin, the assistant psychology professor leading the research, which involves measuring drives’ reaction time and brain activity as they respond to auditory and visual cues.
The researchers just completed a study of the mental workload involved in driving through different kinds of environments and heavy vs. light traffic. Preliminary results show that as people "get into more challenging driving situations, they don’t have any extra mental energy to respond to something else in the environment," Baldwin said.
But the tradeoffs could be worth it, she said. The next step is to test different ways of giving drivers navigational information and how those methods change the drivers’ mental workload.
"Is it best if they see a picture ’" that shows their position, a map kind of display?" Baldwin said. "Is it best if they hear it?"
Navigational systems now on the market give point-by-point directions that follow a prescribed route. "They’re very unforgiving," Baldwin said. "If you miss a tarn, they can almost seem to get angry."
That style of directions also can be frustrating for people who prefer more general instructions. But such broad directions can confuse drivers who prefer route directions, Baldwin said.
Perhaps manufacturers should allow drivers to choose the style of directions they want, or modify systems to present some information in a way that makes sense for people who prefer the survey style, she said.
Interestingly, other research has shown that about 60 per cent of men prefer the survey style,
while 60 per cent women prefer the route style, Baldwin said. This explains the classic little thing of why men don’t like to stop and ask for directions and women do, Baldwin added.
选项 A、If Coyne had stopped the car in time, he wouldn’t have hit the woman.
B、The woman would have been knocked over, if Coyne had followed the traffic regulations.
C、Coyne is not really driving so it is impossible for him to have hit the woman.
D、If the woman had not crossed the street suddenly, Coyne would not have hit her.
答案C
解析 注意到备选项中都涉及到了Coyne和the woman,所以重点注意包含这些词的句子。 Joe Coyne slides into the driver’s seat, stars up the car and heads to town. The empty stretch of interstate gives way to urban congestion, and Coyne hits the brake as a pedestrian suddenly crosses the street in front of him. But even if he hadn’t stopped in time, the woman would have been safe. She isn’t real.  (即使他没有及时刹车，那位妇女也是安全的)。根据划线句的肉容可以直接判断C是答案。
