It was the day of the big cross-country run. Students from seven different primary schools in and around the small town were warming up and walking the route(路线)through thick evergreen forest.

I looked around and finally spotted David, who was standing by himself off to the side by a fence. He was small for ten years old. His usual big toothy smile was absent today. I walked over and asked him why he wasn’t with the other children. He hesitated and then said he had decided not to run.

What was wrong? He had worked so hard for this event!

I quickly searched the crowd for the school’s coach and asked him what had happened. “I was afraid that kids from other schools would laugh at him,” he explained uncomfortably. “I gave him the choice to run or not, and let him decide.”

I bit back my frustration(懊恼). I knew the coach meant well—he thought he was doing the right thing. After making sure that David could run if he wanted, I turned to find him coming towards me, his small body rocking from side to side as he swung his feet forward.

David had a brain disease which prevented him from walking or running like other children, but at school his classmates thought of him as a regular kid. He always participated to the best of his ability in whatever they were doing. That was why none of the children thought it unusual that David had decided to join the cross-country team. It just took him longer—that’s all. David had not missed a single practice, and although he always finished his run long after the other children, he did always finish. As a special education teacher at the school, I was familiar with the challenges David faced and was proud of his strong determination.

7 . Alice Moore is a teenager entrepreneur(创业者), who in May 2015 set up her business AilieCandy. By the time she was 13, her company was worth millions of dollars with the invention of a super-sweet treat that could save kids’ teeth, instead of destroying them.

It all began when Moore visited a bank with her dad. On the outing, she was offered a candy bar. However, her dad reminded her that sugary treats were bad for her teeth. But Moore was sick of missing out on candies. So she desired to get round the warning, “Why can’t I make a healthy candy that’s good for my teeth so that my parents can’t say no to it?” With that in mind, Moore asked her dad if she could start her own candy company. He recommended that she do some research and talk to dentists about what a healthier candy would contain.

With her dad’s permission, she spent the next two years researching online and conducting trials to get a recipe that was both tasty and tooth-friendly. She also approached dentists to learn more about teeth cleaning. Consequently, she succeeded in making a kind of candy only using natural sweeteners, which can reduce oral bacteria.

Moore then used her savings to get her business off the ground. Afterwards, she and her father secured their first business meeting with a supermarket owner, who finally agreed to sell Moore’s product—CanCandy.

As CanCandy’s success grows, so does Moore’s credibility as a young entrepreneur. Moore is enthusiastic about the candy she created, and she’s also positive about what the future might bring. She hopes that every kid can have a clean mouth and a broad smile.

Meanwhile, with her parents’ help, Moore is generally able to live a normal teenage life. Although she founded her company early on in life, she wasn’t driven primarily by profit. Moore wants to use her unique talent to help others find their smiles. She donates 10% of AilicCandy’s profits to Big Smiles. With her talent and determination, it appears that the sky could be the limit for Alice Moore.

Ali and his younger sister, Zahra, lived with their parents in a poor neighborhood. Their mother was very sick and their father was struggling to find a job, and they had only a little money with which to buy food. As they had not paid the rent for several months, the landlord was breathing down their necks.

One day, Ali took Zahra's shoes to a shoe repairman to be fixed, but he lost them on the way home. It wasn’t until he got home that he realized he had lost the shoes. He was afraid that his parents would be angry and disappointed, so he begged his sister to keep it a secret. Zahra agreed and the two decided to share Ali’s running shoes. Zahra's school hours were in the morning, so she would wear them first. After school, she would rush back and give them to Ali. He could then run to his school, which began in the afternoon. Although he ran as fast as he could, Ali often arrived late and was warned by the school.

Ali heard about a long distance race that was held for the boys in the city.When he learned that the third prize was a new pair of shoes, he decided to take part. He ran home excitedly and promised his sister that he would win her the new shoes.

The day of race arrived. Ali had a strong start, but halfway through the race he began to get tired and his legs began to ache. Getting more and more exhausted he thought only of Zahra and his promise to her. Dreaming of the new shoes he would win for his sister gave him strength, and he stayed right behind the two fastest runners, determined to finish third. Suddenly, as the finish line drew near, another runner collided(碰撞) with Ali from behind and he crashed to the ground.

Ali looked up and saw the other boys rushing ahead.

Filled with delight, Ali walked home quickly.
