When Emma Yang was seven years old, her grandmother became forgetful. Over the next few years, those memory problems, caused by early Alzheimer's disease, worsened. Yang, who learned to write computer programs at an early age, decided to create an app to help. "When I was about 11, I got really interested in using technology for social good to help other people around the world ," says Yang, who is now 14.

In her app called Timeless, Alzheimer's patients can look through photos of friends and family, and the app will tell them who the people are and how they're related to the patients. The app also includes a simple reminder screen that lists appointments for the day, along with a simple contacts screen that shows photos of family members along with names. If a patient tries to call a contact repeatedly, the app will flash a quick reminder: "You just called less than five minutes ago." A "me" page shows the patient's own name, age, phone and address.

"There are no apps that really help Alzheimer's patients with their daily lives, "Yang says. "A lot of times people think that the elderly can't really use technology,but in fact,if you introduce it to them carefully,it can really benefit their lives. "

Catherine Possin,an associate professor at the UCSF Memory and Aging Center,agrees. "It can be hard for somebody who has a lot of memory problems to learn a new technology,"Possin says. "But if the app is simple enough,they can learn to use it through practice. "

Looking through the photos,Possin says,can be a type of social activity for the patient,helping keep family members and friends in mind. It also could strengthen memory. "I think it can be very helpful for patients to exercise memories and make them stronger and make them more resilient(可迅速恢复的)in the face of the disease."

1.What is the "contacts screen" made for?

A.To show the list of appointments for the day.

B.To show the patient's own information.

C.To show photos of family members.

D.To show the changes in the patient

2.The underlined word "them" refers to "______".

A.old people B.Alzheimer's patients C.apps D.technologies

3.What can we learn from Katherine Possin?

A.It is easy for Alzheimer's patients to learn to use apps.

B.The app can help Alzheimer's patients strengthen their memory.

C.The UCSF Memory and Aging Center is helping Yang develop the app.

D.Social activities can help Alzheimer's patients remember things about themselves.

4.What is the best title for the passage?

A.A Perfect App for the Patients-Timeless

B.Young Developer of an Alzheimer's App

C.New Medicines to Cure Alzheimer's

D.A Talented Student-Emma Yang
