2 . A 15-year-old scientist and inventor has been named as Time's first ever Kid of the Year.
Rao is a high school student from Colorado. She was chosen from 5,000 U.S.-based nominees ( 提 名 ). Time said in a statement that Rao stood out for her ability to apply scientific ideas to real-world problems and her efforts to motivate other kids to take up their own causes. Rao told the Associated Press that the prize is “nothing that I could have ever imagined. And I'm so grateful and just so excited that we're really taking a look at the upcoming generation and our generation, since the future is in our hands.” She insists that starting out small doesn't matter, as long as you're enthusiastic about it.
It's just the latest recognition for the teenager, who was named last year to the Forbes 30 Under 30 list. Rao won praise in 2017 after she developed a portable device（设备） to detect lead (铅) in water. She went on to cooperate with scientists in the water industry to try to get the device on the market.
The young scientist has also developed an app called Kindly that uses artificial intelligence to help prevent cyberbullying (网络欺凌). It allows teens to type in a word or phrase to find out if the words they're using are hurtful and amount to（等于）bullying, and thus should be avoided.
In an interview with Time, Rao said that her pursuits（追求） in science started early as a way to improve conditions in society. In a world where science is increasingly questioned or challenged, Rao insists that its pursuit is an important act of kindness. It is the best way that a younger generation can better the world. Science and technology are being employed as never before to handle various issues, such as global warming, the outbreak of disease and so on, she noted.
“We have science in everything we're involved in, and I think that's the biggest thing to put out there, that science is cool, invention is cool, and anybody can be an inventor," Rao said.“ Anybody can do science.
