Studies over the past decade at the University of Utah show that hands-free cellphones are just as harmful to drivers as hand-held ones because it is the conversation, not the phone, that is distracting(分散)their attention. "Even though your eyes are looking right at something, when you are on the cellphone, you are not as likely to see it," says Professor David Strayer. "Ninety-nine percent of the time, it’s not that critical(危急的), but that 1% could be the time a child runs into the street," he adds.
Dr. Strayer’ s studies have also found that talking on a cellphone is far more distracting than talking with a passenger. Listening to the radio, to music or to a book on tape also isn’ t as distracting, because it doesn’ t require the same level of interaction as a conversation. But even drivers may miss some details of a book on tape if their attention is focused on driving tasks. Some people can train themselves to pay extra attention to things that are important—like police officers learn to search faces in crowds.
And the Utah researchers have found a rare group of "super-taskers"—about 2. 5% of the population—who seem able to attend to more than one thing with ease.
Many more people think they can effectively do several things at the same time, but they are really turning their attention rapidly between two things and not getting the full effect of either. Clearly, it is easier to put some tasks together than others. " Not all distractions are the same," says Dr. Strayer. Things like cleaning and working out can be done automatically(自动地)while the mind is focused elsewhere. But doing homework and texting at the same time isn’ t possible. Even talking and watching TV is difficult. "Just try talking with your wife while watching football. It’s impossible," jokes Dr. Strayer.
What does the example of police officers in Paragraph 2 show?
选项
A、Searching for faces require more attention than driving.
B、Talking to a crowd calls for a high level of attention.
C、One’ s attention can be easily distracted in crowds.
D、The ability to attend to two tasks can be trained.
答案
D
解析
推理题。题干意为“第二段中警官的例子说明什么?”。从文章第二段最后一句话“Some people can train themselves to payextra attention to things that are important——like police officers learnto search faces in crowds.”可以得知,这种能力是通过“train themselves”获得的。故D正确。
