　　Section C

　　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.

　　Passage Two

　　Question 52 to 56 are based on the following passage.

　　In agrarian(农业的),pre-industrial Europe, "you'd want to wake up early, start working with the sunrise, have a break to have the largest meal, and then you'd go back to work," says Ken Albala, a professor of history at the University of the Pacific, "Later, at 5 or 6, you'd have a smaller supper."

　　This comfortable cycle, in which the rhythms of the day helped shape the rhythms of the meals, gave rise to the custom of the large midday meal, eaten with the extended family, "Meal are the foundation of the family,' says Carole Couniban. a professor at Millersville University in

　　Peensylvania, "so there was a very important interconnection between eating together" and strength-eating family ties.

　　Since industrialization, maintaining such a slow cultural metabolism has been much harder. With the long midday meal shrinking to whatever could be stuffed into a lunch bucket or bought at a food stand. Certainly, there were benefits. Modern techniques for producing and shipping food led to greater variety and quantity, including a tremendous, increase in the amount of animal protein and dairy products available, making us more vigorous than our ancestors.

　　Yet plenty has been lost too, even in cultures that still live to eat. Take Italy. It's no secret that the Mediterranean diet is healthy, but it was also a joy to prepare and cat. Italians, says Counihan, traditionally began the day with a small meal. The big meal came at around 1 p.m. In between the midday meal and a late, smaller dinner came a small snack. Today, when time zones have less and less meaning, there is little tolerance for offices' closing for lunch, and worsening traffic in cities means workers can't make it home and back fast enough anyway. So the formerly small supper after sundown becomes the big meal of the day. the only one at which the family has a chance to get together. "The evening meal carries the full burden that used to be spread over two meals" says Counihan

　　B.They were so busy working that they only ate simple meals.

　　C.Their daily routine followed the rhythm of the natural cycle.

　　B.It brought family members closers to each other.

　　C.It was characteristic of the agrarian culture.

　　D.It enabled families to save a lot of money.

　　【答案】B
