Attitudes toward new technologies often fall along generational lines. That is, generally, younger people tend to outnumber older people in face of a new technology.
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 disagree 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 fact 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 included.
When it comes to driverless cars, differences in attitude are obvious 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 lived 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, a person’s age will have little to do with how self-driving cars can become mainstream. Once driverless cars are really available for sale, the early adopters will be the people who can afford to buy them.
1. What usually happens when a new technology appears?
A. It benefits society greatly.
B. The old are not happy with it.
C. People of different ages respond differently.
D. It will separate the old from the young.
2. What does the author say about the driverless car?
A. It makes people’s life more convenient.
B. It can lead to fewer road accidents.
C. It may start a change in the car industry.
D. It does not seem to create a generational divide.
3. What is likely to affect a person’s attitude towards the driveless car?
A. The field of his special interest.
B. The location of his living place.
C. The amount of his driving training.
D. The length of his driving experience.
4. Who are the most potential customers of the driverless car?
A. The seniors. B. The wealthy.
C. The educated. D. The car lovers.
IV.七选五
There have been a lot of comments recently surrounding 5G, the next generation of wireless technology. 1 How might it change our lives?
5G stands for the fifth generation, meaning the next step in the progression of technology to replace the current 4G system. Earlier “G” systems were designed to improve mobile communication operations. Each new technology brought major improvements in speed and greatly increased network capacity (容量). 2It is expected to permit more users to do more things at a faster rate.
However, technology experts say there is a major way that 5G is different from the earlier systems. 3 It will affect more devices and industries than other “G” versions.
5G will help fuel future “smart cities” by connecting sensor networks. 5G is also expected to connect self-driving cars and support new technologies involving virtual reality (虚拟现实). Higher 5G speeds could also permit doctors to commonly perform remote medical operations. Factories and businesses could use 5G technology to increase automation and improve the collection of information.
4The increased data flow across 5G networks would give Internet attackers a lot more possibilities to steal and misuse data. In addition, the wider use of a 5G wireless network means any breakdown of the system would have more widespread and severe results. Such difficulties could affect public safety. 5 or a network breakdown could cause self-driving vehicles to crash.
A. Why is 5G so popular?
B. What is this technology?
C. Every coin has two sides.
D. The new 5G system promises more of the same.
E. It will move beyond mobile network technology.
F. A breakdown of 5G networks may cause economic losses.
G. A failure during a doctor’s remote operation could lead to death.
