【单选题】{{B}}第二篇{{/B}}
JoeCoyne slides into the driver’s seat, stars up the car and heads to town. The empty stretch of interstate gives way to urban congestion, andCoyne 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.AndCoyne isn’t really driving.Coyne is demonstrating a computerized driving simulator that is helping researchers at OldDominion 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," saidCarylBaldwin, 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、
B．is designing an audio navigational information system
C．is designing an audio-visual navigational information system
D．want to determine the best ways of giving navigational information system
网考网参考答案：D
网考网解析：
[解析] 该题问及第6段的大意。注意到在该段中出现了navigational information，而“方法”这个词义在该段中重复出现了两次。(But the tradeoffs(交替使用)could be worth it，she said．The next step is to test different ways of giving drives navigational information and how those methods change the drivers mental workload．)因此判断“方法”是该段的主题词，因此判断D是答案。 document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
