【导读】这篇文章是一篇记叙文。青少年创造家Gitanjali Rao从10岁初步就一向在为处置世界疑问而想出各种立异处置方案。这篇文章介绍了她的三种创造和她所获得的荣誉。
Most teenagers are still trying to 
find their passion and purposes in life. However, not Gitanjali Rao. The 15-year-old girl has been coming up with innovative solutions to worldwide problems since she was ten. It is, therefore, not surprising that the teenager has won the honor of “America's Top Young Scientist”．
In the third grade, Rao was inspired to build a device after witnessing the shocking story unfold in Flint, Michigan, where cost-cutting measures led to the use of a polluted river as the city's primary water supply and incredibly high levels of lead made their way into people's drinking water.
After two months' research, Rao designed a small and portable device that used sensors to instantly detect lead in water. Called Tethys, after the Greek Goddess (女神) of freshwater, it attaches to a cellphone and informs the residents via an app
if their drinking water contains lead. The design earned her the 3M Young Scientist Challenge in 2021. She is currently working with scientists and medical professionals to test Tethys' potential and hopes the device will be ready for commercial use.
Later, Rao took on another social issue-drug addiction. Her app, called Epione, which won the Health Pillar Prize at the TCS Ignite Innovation Student Challenge in May 2021, is designed to catch drug addiction in young adults before it's too late.
More recently, the teenager has developed an app named Kindly, which uses artificial intelligence technology to detect possible signs of cyberbullying (网上欺负). When users type in a word or phrase, Kindly is able to pick it up if it's bullying, and then it gives the option to edit it or send it the way it is. It gives them the chance to rethink what they are saying so that they know what to do next time.
All kinds of awesome, Gitanjali Rao has been selected from 5,000 equally impressive nominees (被提名人) for TIME Magazine's first-ever “Kid of the Year”．
