Ⅰ. 阅读理解

A

(2025·江西景德镇期中)When Stanford University student Ellen Xu，now 18，was a five-year-old in San Diego，California，she clearly remembers that her parents rushed her little sister to the hospital.Three-year-old Kate had fallen seriously ill; she had a fever，reddened eyes，and some swelling in her hands and tongue.

At first，the puzzled doctors thought she had flu，but when her condition didn't improve，the Xus returned to the clinic room，where a doctor by chance had a similar earlier experience with such symptoms in the blood known as Kawasaki disease.Though rare，it's the leading cause of the heart disease in babies and young children，and its causes remain unknown.

The doctor knew how to treat it: He ordered some medicine for Kate，and finally she shook off

the illness without suffering damage to her heart.

Xu remembers being curious about her sister's illness condition and was amazed that the grown-ups couldn't answer her questions about why it was so hard to check.“In my mind，it was this puzzle I wanted to solve，” she says.

Ten years later，wanting to enter a high school science fair，she had an idea：“What if we had a doctor in our pocket？”So she created just that: Using AI，Xu designed a program that uses visual facts to check the disease based on five physical symptoms.

The technology works the same way as apps that can identify birds and plants with photos you've taken on your cellphone.Worried parents can upload a photo that they have taken of their child，and the technology will scan the picture for symptoms of the disease，which often have strong visual factors，such as a swollen tongue.

Xu's invention has been applied as a web app on the website.“The technology could also be developed for recognizing some other diseases，” she says.“It means a lot to me.I want to use AI to help people live happier and healthier lives.”

Xu says that her sister Kate，now in her third year of high school with dreams of becoming an environmental engineer，is strong and healthy.
