四、阅读与回答问题。〔人与社会——社会服务与人际沟通〕
Worldwide，millions of people are waiting for calls from strangers. Some of them consider themselves introverts(内向的人). Some say they hate talking on the phone. But as volunteers for Be My Eyes，they all have a kind heart.
Be My Eyes was created in 2015 by Hans Jorgen Wiberg from Denmark. This free app connects blind people with sighted volunteers through video calls for help with everyday tasks. Wiberg used to worry about finding enough volunteers. But today volunteers outnumber blind users by ten to one.
It's not easy for volunteers to get a call. Zhang Yanfei joined Be My Eyes in 2019 but didn't receive her first call until four years later. Calls go out to many volunteers at the same time. If one doesn't respond immediately，another volunteer will take the call.
He Yanyan，a stage actress，hesitated(犹豫) to join at first. She feared missing calls during rehearsals(排练). After learning that other volunteers would cover missed calls，she signed up at once. She received her first call the very next day. A young man nervously asked，“Can this app really help?” Feeling nervous herself，she realized the man was also new to the platform. She described the objects around him. The caller was relaxed and asked if he looked tidy. After she told him that his clothes were spotless，the conversation continued for a few more rounds until the call was suddenly cut off. The volunteer wondered if she had sounded unfriendly.
Cao Zhenxiang was also nervous during his first call. After he helped an elderly man check the expiration date(有效期) on his bread，the two thanked each other repeatedly. “I was so nervous that I didn't even know why I was thanking him，” he said.
Now，Cao feels much more confident. He recently helped a blind person cross the street while working on his computer. “It just felt like chatting with a friend，” he said.
