Safer Internet Activities
To help schools promote safer internet messages to families, the Education Safeguarding Service's Online Safety Team has worked with Kent Children's University to produce a Safer Internet Day Challenge pack for children aged 5 to 14.
This pack contains 10 key challenge activity ideas, as well as useful resources for children, schools and families to access. The Challenge will run until 31 March so there is plenty of time to get involved.
The Safer Internet Day Challenge starts with schools and families today and you can find the resources here. So why not send the activities home to your parents or caregivers so families can get involved?
Young people who are part of Kent Children's University can earn a varying number of Learning Credits for each activity completed outside normal school time.

B
When Stanford University student Ellen Xu 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 (肿胀) 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 previously seen similar symptoms (症状) in a patient diagnosed with Kawasaki disease (川崎病). Though rare, it's the leading cause of heart disease in babies and young children, and its causes remain unknown.
The doctor knew how to treat it: He gave medicine to Kate, and finally she recovered without any damage to her heart.
Xu remembers being curious about her sister's illness 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 a 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 data to detect (检测) Kawasaki 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 of their child, and the technology will scan the picture for symptoms of Kawasaki disease, which often have strong visual features, such as a swollen tongue.
Xu's invention has been used as a web app. "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.
4. Why did the author mention Kate's illness? ()
A. To explain who treated Kate's illness.
B. To prove how serious Kate's illness was.
C. To show how much Ellen loved her sister.
D. To tell why Ellen wanted to solve the puzzle in her mind.
5. Why did Ellen design the program? ()
A. To save her sister.
B. To earn a prize.
C. To detect a rare disease.
D. To identify birds and plants.
6. Which of the following can best describe Ellen according to the text? ()
A. Determined and careful.
B. Creative and helpful.
C. Diligent and selfless.
D. Active and easy-going.
7. Which is the best title for the text? ()
A. A Girl's Road to Invention
B. An Invention Helping Doctors
C. A Girl Recovering from a Disease
D. A New Method to Treat a Disease
C

语篇解读 本文是一篇记叙文。文章讲述了女孩Ellen Xu利用人工智能技术创建了一个应用程序用以检测川崎病,帮助人们快速获得诊断,改善健康状况。
4. D 推理判断题。前三段叙述了Ellen在5岁时经历了妹妹Kate得川崎病的情景,以及Kate被治愈的过程;第四段介绍因为妹妹的病情,Ellen萌生了想要解决如何检测川崎病这个问题的念头。由此可推知,作者提到Kate的病是为了说明Ellen想解开心中难题的动机。故选D。
5. C 细节理解题。根据第五段中"So she created just that: using AI, Xu designed a program that uses visual data to detect(检测) Kawasaki disease based on five physical symptoms."可知,Ellen设计这款程序是为了检测这种罕见病。故选C。
6. B 推理判断题。根据第五段中"So she created just that:using AI, Xu designed a program ..."可知,Ellen创建了一个可以检测川崎病的程序,所以她是有创造力的;根据倒数第二段中她所说的"I want to use AI to help people live happier and healthier lives."可知,Ellen想用人工智能帮助人们改善生活,所以她是乐于助人的。故选B。
7. A 标题归纳题。通读全文可知,文章主要围绕女孩Ellen Xu发明了一款检测罕见病的应用程序这一经历展开——先是讲述了她这个想法的由来,再描述了她在十年后利用人工智能技术创建了一个程序,可以根据症状检测该疾病并已投入使用。由此可知,A项概括了Ellen的经历,是本文的最佳标题。故选A。
