When Emma Yang was 7 or 8 years old, her grandmother got Alzheimer's disease（阿尔茨海默病）. It made her grandmother lose her memory. She couldn't even know her own family members.Yang, now 14, decided to create an app to help people with this disease.
Her app is called Timeless. It uses facial recognition technology. Alzheimer's patients can use the app to look at photos of their friends and family. The app will tell them who the person is and how they recognize（认出）someone in the same room; they can take pictures and the app will try to identify them.
Yang got the idea after seeing how facial recognition is used in different areas, especially in health care. She worked with a tech company to create the facial recognition software that her app used. She learned to code（编码）for the iPhone for the first time in the process.
The app is still in development. Yang is trying to raise money through crowdfunding（众筹）so that she can take the next step. Though some may think that the app is too hard for older people to use, Yang is hopeful. “If you introduce it to them right away, it's actually possible for them to use it and it can really benefit their lives,” she said.
Memory expert Katherine Possin agreed. Possin said looking at photos on the app can help patients feel more social. It can also improve their memory, she added.

Last summer, I went to a river trek（徒步旅行）with my mother and some British friends. The rocks in the river were so slippery （滑的） that it was hard for us to walk. We walked carefully, but the freezing water still flooded into our shoes and trousers. I was getting very cold and tired. I wanted to give up, but when I saw other kids moving so fast, I decided to follow them, even though I was far behind. It was even more difficult during the last part of the walk. I became so tired that I lost my footing and fell several times. But with the help of my mother and my friends, I got to my feet and kept going each time I fell.
At last, we arrived at a waterfall. Everybody jumped into the river from a high rock. When it was my turn, I was very scared and tried to hide around a corner. My friends noticed this and encouraged me, “Come on, Kevin! You can do this！” With my eyes closed, I jumped into the river.
Although I am not as strong as my British friends, I completed our trek. This experience made me realize that perseverance（坚持不懈）is, and will always be important to everyone in life!
