17．Teenagers in America know that they'll possibly need technical skills to find good jobs，but a new survey reveals that interest in technology-related careers may be decreasing.
The percentage of boys aged 13 to 17 who are interested in science，technology，engineering and math or STEM careers dropped from 36 percent in 2017 to 24 percent this year，according to a survey by Junior Achievement USA.The amount of girls interested in STEM careers stayed unchanged.
But the 1，000 survey participants still named technology as one of two key skills that will be necessary to prepare them for their future careers.
"Kids don't understand how technology can be applied to careers in addition to computers，and maybe robotics，" said Tammera L.Holmes，president of aviation consulting firm AeroStar Consulting（航空咨詢公司）. "That's all they know，so they can't really translate that interest to career pathways."
When Holmes was in high school，her mom sent her to an event that featured（以……為專題）the pilots from World War Ⅱ.One of the pilots took her for a ride and let her take the wheel. "Immediately that was the career for me，" she said.
Women remain outnumbered（超過）by men in fields like technology.For people working to increase the number of women in these areas，the lack of growth in girls，interest in STEM careers is concerning.
Teenage girls are more interested than their male classmates in running after careers in which they can help others，said Ed Grocholski from Junior Achievement.Even with all the programs aimed at increasing girls' interest in STEM，"I don't think we really talk that much about how we improve people's lives through STEM，" Grocholski said.
Society needs to do better at making those connections for kids，said Katherine Latham，founder of an engineering firm.She used civil engineering as an example of a career that will continue to be important.
However，the fact that students know they will need tech skills in their future careers is encouraging.
The second skill they said they need is relationship-building.
"That's going to be the new type of engineers，" Latham said.

B．Teenage girls are interested in running after STEM careers.
C．The relationship between STEM careers and the improvement of people's lives isn't explained enough.
D．Teenagers don't know how to improve people's lives through STEM.

18．Alexa is a form of artificial intelligence，or AI for short.Many people start their mornings by asking Alexa for the weather forecast or the latest news.A device（設(shè)備）that houses Alexa can also play music from your favorite playlists，keep a shopping list，order takeout food，answer questions，send messages and even run "smart" home controls.
Training AI systems to respond to problems with human-like intelligence and learn from their mistakes can take months，or even years.Consider Alexa and similar software，such as Apple's Siri.To do the tasks its human owners ask，these systems must make sense of and then respond to sentences such as，"Alexa，play my Ed Sheeran playlist" or "Siri，what is the capital of India？"
Computers can't understand language as it is spoken by people.So AI researchers must find a way to help humans communicate with computers.The technology used to get computers to "understand" human speech or text is known as natural language processing.By natural language，computer scientists refer to the way people naturally talk or write.To teach an AI system a task like comprehending（理解）a sentence or responding to a person's last move in a board game，scientists need to feed it lots of examples.
AlphaGo is an AI system designed by Google that has beaten a human champion，Lee Sedol，at the strategy（策略）board game Go.To train AlphaGo，Google had to show it 30 million Go moves that people had made while playing the game.Then AlphaGo used what it learned to analyze those plays as it played against different versions （版本）of itself.During this practice，the program came up with new moves - ones never seen in games between people.
（1）What does the example of Alexa show？
A．AI may replace humans one day.
B．AI is playing a role in our modern life.
C．AI has been widely used around the world.
D．AI has totally changed people's bad habits.
（2）How do scientists train AI systems？
A．By testing them thousands of times.
B．By teaching them almost everything.
C．By giving them quite a lot of tasks to do.
D．By providing them with large amounts of data.
（3）What can we learn about AlphaGo？
A．It has become very skillful and intelligent.
B．It is the most convenient AI system.
C．It avoids making any mistakes.
D．It just follows human orders.組卷：12引用：1難度：0.5
