How do you get money? From your parents or your work? Do you spend it or save it?

Let’s check out how four teenagers in Britain get money and do with it.

Bob, a ten-year-old boy, was playing on the grass in a garden. He enjoyed the singing birds, colorful butterflies and the lovely squirrels. It was their own free kingdom. Bob felt like an outsider. He decided to give them space to enjoy freely.

He lay on the grass, feeling like sunbathing on a beach. As he enjoyed the blue sky, he couldn’t help thinking, “What a wonderful world it is!”

Bob was always ready to help others, whether animals or humans. He thought of keeping water in a bowl for watering the birds and animals. Bob stretched out his hands and saw some squirrels. He fed the squirrels some biscuits.

Suddenly, a small bird fell to the ground before his eyes. Being a crazy animal lover, he couldn’t stand seeing the little bird’s pain.

He remembered his teacher’s advice to do a good deed (行为) every day, and he decided to take care of the bird. He picked up the bird and rushed to his room, where he found some cold ice in the fridge and sprinkled (喷洒) water on the bird. The bird woke up after being given water.

Then Bob said that he had done a good job for the day, as his teacher, Miss Green, had taught in the class.

Overjoyed by Bob’s kindness, his mother and his teacher praised him for his good deed. Bob smiled, feeling proud of himself and knowing that he had done something good in the world. He felt a sense of peace and enjoyment. He knew that he had made a small difference in the world. He looked up at the sky, feeling thankful for the beauty of the world and the kindness in people’s hearts.

Do you often ask questions? Children are known for wanting answers to many questions, because curiosity (好奇心) is part of human nature. Books and TV shows often depend on curiosity. People keep reading or watching because they want to find out what happens.

As we know, curiosity provides many advantages. Many of history’s greatest discoveries were made by curious people. People wondered how things worked and how work could be done more quickly. Thanks to their curiosity, people now know far more about the world and have useful technology to help them. Even if you don’t plan to be an inventor or researcher, curiosity can still help you in the classroom. If you develop the curiosity of learning, classes will become more interesting. You will be good at them because you enjoy the process of learning. Even if you’re no longer a student, curiosity will make you an able worker.

What will you do if you’re not already curious? Luckily, curiosity is a skill that can be improved. Often, the more you learn about a topic, the more interesting it becomes. To improve your curiosity, get information from as many sources (来源) as possible when you learn about a topic. At the same time, read all kinds of books, watch or listen to speeches and ask questions. Don’t always get information in the same way. Instead, learn to understand the facts that different people know.

Don’t assume you already know everything. Instead, search for other possibilities and opinions. Remember, everyone knows something that you don’t know. Find out what it is, and ask about it. This lets you learn something and makes the other people happy by letting them show off their knowledge. Let’s try to become people who are full of curiosity.
