Tony is from New York. His father has a store there. And his mother is a reporter. He's six years old now and begins to go to school this year. It's very near their shop and his father doesn't drive a car to take him to school. He walks to school early every day. So he's not late for class and his teachers like him.

    It's Tuesday today. Miss White is teaching them to count from one to ten. Tony is studying hard. Soon he can count them. Miss White is happy and asks, "How many people are there in your family, Tony?"

    Tony stands up and begin to count with his fingers, and then says, "Two, Miss White."

    "Who are they?"

    "My father and my mother."

    "Oh?" Miss White is surprised, "Two people in your family?"

    "Because now I'm not at home."

    As a rule, we have a test about some usual things in our life every two months. During my second month of nursing school, our teacher gave us a pop test as usual.

    I was a serious, hard-working and careful student, so I passed the questions easily until I read the last one, "What is the first name of the woman who cleans the school?"

    I thought this was sure some kind of joke. I saw the cleaning woman several times. She was tall, dark hair and in her 50s, but how would I know her name? I handed in my paper, leaving the last question blank.

    Before the class ended, one student named Nancy asked our teacher if the last question would count toward our test grade. This was also all the students' question. We all wondered why he gave this question in the test, because we all felt it meaningless.

    "Certainly," said our teacher. "In your life you will meet many people. All of them are important. They should get your attention and care, even if all you do is smile or just say an easy 'hello' ." We all kept silent after hearing this.

    I've never forgotten that special lesson. I also learned her name was Dorothy.

    Alice Lee is a high school student studying at a private school. She is doing some voluntary work at an after-school program to help students from poor families.

    On the first day of her work, she noticed that many kids were lining up for free sandwiches and fruits. She was surprised. One of the organizers explains that many of these students don't get enough to eat at home. So a school lunch or an after-meal might be the most food they would get all the day. She has also been told that some hungry kids can receive free lunches, but others are only allowed reduced-price meals, and those students' families have to pay for the part of their food.

    Lee was shocked, she decided to offer help to those who are suffering from hunger, "I want other kids to understand that if you see a problem, you don't have to wait to be an adult to fix it," says Lee. She and a group of friends are using their programme skill to create a new app called Food of Thought, which will allow parents, students, and even kind-hearted strangers to donate money to lunch accounts for students in a nearby school.
