The first robots were invented in the 1920s. Robots     1     (appear) in many American films. In some films, they are stronger, faster and     2     (clever) than people.

In real life, robots are     3     (main) used in factories. They do some dangerous and difficult jobs for humans.

Robots also help disabled people, for example, blind people. Today many blind people have a guide dog     4     (help) them. In the future, guide dogs might be robot dogs.

One kind of robot guide dog has wheels. It moves in front of the owner. It is very clever. It knows the speed of its owner. The owner     5     (wear) a special belt. This belt sends instructions to the owner     6     the dog, such as “stop here”, “turn left” or “turn right”.

In the United States, another kind of robot helps disabled people to take care of     7     (they) in their life. The robot hears the sound of its owner’s voice. It follows instructions such as “turn the page” or “make a cup of coffee”.

Robots are also useful in American hospitals. They can do simple jobs. At one hospital, for example,     8     robot takes meals from the kitchen to patients’ rooms. It never gets lost     9     this robot has a map of the hospital in its computer memory.

Though robots can help people in many different ways, they will never take the place of     10     (human).

5 . When a business owner, Alcide Dominique, found a helpless man sleeping in front of his office one morning, he decided to do something for him.

Dominique allowed the man to stay there and did not disturb (打扰) him. Dominique and one of his staff members, Sean, gave the homeless man a hot meal and paid for a night’s stay in a hotel. He formed a friendship with the man, 33-year-old Jim Brown.

“All we were doing was just being a friend, getting him something to eat and getting him a room,” he said. “That’s all that we wanted to do.” However, that isn’t all that happened.

Sean took a video of the conversation between Dominique and Brown and shared it online and the video became a hit very soon.

Many online viewers (观看者) were moved and they also wanted to help Brown.

A GoFundMe website was set up and it has raised more than $30,000 so far for Brown, who became homeless after his grandparents died a few years ago.

Dominique and Sean are trying to find low-rent (租金低的) housing, a part-time job and transportation, like a bicycle or a car for Brown so that he doesn’t stay homeless.

Brown thanks Dominique so much for all the help from him, as well as Sean and all the online viewers. “Without him and Sean, I’d be nowhere. Without you all, I would be nowhere,” he said.

    1     The delivery driver is Gao Zhixiao, who was on the cover of Time magazine for March 19.

Born in a poor family in Ningxia, Gao went to Beijing to get a job at the age of 19. He tried different jobs to make a living. He worked as a shopping worker before he finally became a delivery driver.

After the outbreak of the COVID-19, Gao and his wife decided to stay in Beijing rather than (而不是) come back to Ningxia.     2     Gao drives more than 161 kilometers on his motor-bike to finish 40 to 70 orders every day. And people need delivery services more than ever.

Gao once got an order that asked him to buy medicine for an old woman from a hospital far away.     3     Because he thought the old woman might be in great need of the medicine. The old woman lived by herself. Gao first drove to her home to get the prescription (处方) paper, and then he drove quickly to the hospital to get the medicine.     4    

“I think the reason why Time picked me is that I helped an old person in need. Although it is a warm story, I’m not different when helping anyone else,” he says.     5    

Different people like different festivals. For me, I like International Volunteer Day best. It’s on December 5th. Luckily, I was born on that day.

I once worked as a volunteer at a Children’s Hospital in a small Town in South Africa. My job was to help make the kids feel happy while they were staying in the hospital. It maybe sounds interesting. But some people can’t understand why I did it.

I did volunteering mainly because it could help build a better future for people, no matter who or where they are. In this big world, so many people are in need of help.

Look at the children in the hospital where I worked. They felt scared (害怕的) and lonely when they faced all the difficulties since their parents also had other kids to care for. So, why not try to help as many people as possible?

Volunteering in Africa and helping people there let me see other parts of this planet (星球). And volunteering at the hospital showed me a side of the world I did not know about before. I met people from all over the world who have their own ideas, experiences (经历) and dreams. We got to share so much with each other.

I really felt close to these people. We shared amazing memories (记忆) and grew together. I wanted to go back to my country with new experiences and ideas so that, together, we can help more people and make a better future for everyone.

If everyone can lend a helping hand, the world will be more and more beautiful!

10 . It was raining, but thousands of people were still running the marathon. The annual Toronto Marathon was on May 1st and it interested more than 14,000 runners worldwide. And     1    .

I got there at 6:30 in the morning to help set up a station. Volunteers filled up water in cups and passed them to the runners. As the runners were in a hurry, they would just throw the cups on the ground. So     2    . When I did that, so many people said “thank you”. I felt warm even though it was raining and very cold. But when I was picking up cups, a runner threw a cup at me,     3    , then I thought he might have just been trying to do me a favor.

After I worked for about an hour,     4    . I kept on picking up cups, but I didn’t feel tired at all. It was probably because all the runners were so energetic and excited. They encouraged me. I learned a lot from volunteering. I know that we should always think about things from another person’s perspective. Maybe what you saw is not what people actually wanted to do. Furthermore, we need to exercise more to keep fit.     5    . Let’s enjoy it and join it.
