Section C(2016年6月英语四级卷三试题及答案)
Passage One
Questions 47 to 51 are based on the following passage.
Attitudes toward new technologies often along generational lines. That is, generally, younger people tend to outnumber older people on the front end of a technological shift.
It is not always the case, though. When you look at attitudes toward driverless cars, there doesn't seem to be a clear generational divide. The public overall is split on whether they'd like to use a driverless car. In a study last year, of all people surveyed, 48 percent said they wanted to ride in one, while 50 percent did not.
The face that attitudes toward self-driving cars appear to be so steady across generations suggests how transformative the shift to driverless cars could be. Not everyone wants a driverless car now and no one can get one yet but among those who are open to them, every age group is similarly engaged.
Actually, this isn't surprising. Whereas older generations are sometime reluctant to adopt new technologies, driverless cars promise real value to these age groups in particular. Older adults, especially those with limited mobility or difficulty driving on their own, are one of the classic use-cases for driverless cars.
This is especially interesting when you consider that younger people are generally more interested in travel-related technologies than older ones.
When it comes to driverless cars, differences in attitude are more pronounced based on factors not related to age. College graduates, for example, are particularly interested in driverless cars compared with those who have less education, 59 percent of college graduates said they would like to use a driverless car compared with 38 percent of those with a high-school diploma or less.
Where a person lives matters, too. More people who lives in cities and suburbs said they wanted to try driverless cars than those who lived in rural areas.
While there's reason to believe that interest in self-driving cars is going up across the board, a person's age will have little to do with how self-driving cars can be becoming mainstream. Once driverless cares are actually available for safe, the early adopters will be the people who can afford to buy them.
