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.

A visually-challenged man from Beijing recently hiked (徒步) 40 days to Xi’an, as a first step     1     (journey) the Belt and Road route (路线) by foot.

On the 1,100 kilometer journey, the man Cao Shengkang,     2     lost his eyesight at the age of eight in a car accident, crossed 40 cities and counties in three provinces. Inspired by the Belt and Road Forum for International Cooperation     3     (hold) in Beijing, Cao decided to cover the route by hiking as a tribute (致敬) to the ancient Silk Road.     4     friend of his, Wu Fan, volunteered to be his companion during the trip.

Cao and Wu also collected garbage along the road, in order to promote environmental     5     (protect). Cao believes this will make the hiking trip even more     6     (meaning). The two of them collected more than 1,000 plastic bottles along the 40-day journey.

In the last five years. Cao     7     (walk) through 34 countries in six continents, and in 2016, he reached the top of Kilimanjaro, Africa’s     8     (high) mountain.

Now, Cao has started the second part of his dream to walk along the Belt and Road route. He flew 4, 700 kilometers     9     Xi’an to Kashgar on Sept. 20,     10     (plan) to hike back to Xi’an in five months.

The Meredith family lived in a small community. As the economy was in decline, some people in the town had lost their jobs. Many of their families were struggling to make ends meet. People were trying to help each other meet the challenges.

Mrs. Meredith was a most kind and thoughtful woman. She spent a great deal of time visiting the poor. She knew they had problems, and they needed all kinds of help. When she had time, she would bring food and medicine to them.

One morning she told her children about a family she had visited the day before. There was a man sick in bed, his wife, who took care of him and could not go out to work, and their little boy. The little boy -his name was Bernard-had interested her very much.

“I wish you could see him,” she said to her own children, John, Harry, and Clara. “He is such a help to his mother. He wants very much to earn some money, but I don't see what he can do.”

After their mother left the room, the children sat thinking about Bernard. “I wish we could help him to earn money,” said Clara. “His family is suffering so much.”

“So do I,” said Harry. “We really should do something to assist them.”

For some moments, John said nothing, but, suddenly, he sprang to his feet and cried, “I have a great idea! I have a solution that we can all help accomplish(完成).”

The other children also jumped up all attention. When John had an idea, it was sure to be a good one. “I tell you what we can do,” said John. “You know that big box of corn Uncle John sent us? Well, we can make popcorn(爆米花), and put it into paper bags, and Bernard can take it around to the houses and sell it.”

In ancient China lived an artist    1     paintings were almost lifelike. The artist’s reputation had made him proud. One day the emperor wanted to get his portrait (画像) done so he called all great artists to come and present their     2     (fine) work, so that he could choose the best. The artist was sure he would    3    (choose), but when he presented his masterpiece to the emperor’s chief minister, the old man laughed. The wise old man told him to travel to the Li River～perhaps he could learn a little from the greatest artist in the world.

Filled with     4     (curious), the artist packed his bags and left.     5     he asked the villagers on the banks of the river where he could find the legendary (传奇的) artist, they smiled and     6     (point) down the river. The next morning he hired a boat and set out     7     (find) the well-known painter. As the small boat moved,     8     (gentle) along the river he was left speechless by the mountains being silently reflected in the water. He passed milky white waterfalls and mountains in many shades of blue. And when he saw the mists rising from the river and the soft clouds    9     (surround) the mountain tops, he was reduced to tears. The artist was finally humbled (谦卑) by the greatest artist     10     earth, Mother Nature.

During this past year, I’ve had three instances of car trouble. Each time these things happened, I was sick of the way most people hadn’t bothered to help. One of those times, I was on the side of the road for close to three hours with my big Jeep. I put signs in the windows, big signs that said NEED A JACK (千斤顶), and offered money. Nothing. Right as I was about to give up, a Mexican family in a small truck pulled over, and the father bounded out.

He sized up the situation and called for his daughter, who spoke English. He conveyed through her that he had a jack but that it was too small for the Jeep, so we would need something to support it. Then he got a saw (锯子) from the truck and cut a section out of a big log on the side of the road. We rolled it over and put his jack on top, and we were in business.

I started taking the wheel off, and then, if you can believe it, I broke his tire iron. No worries: He handed it to his wife, and she was gone in a flash down the road to buy a new tire iron. She was back in 15 minutes. We finished the job, and I was a very happy man.

The two of us were dirty and sweaty. His wife prepared a pot of water for us to wash our hands. I tried to put a $20 bill in the man’s hand, but he wouldn’t take it, so instead I went up to the truck and gave it to his wife as quietly as I could. I asked the little girl where they lived. Mexico, she said. They were in Oregon so Mommy and Daddy could work on a fruit farm for the next few weeks. Then they would go home.

When I was about to say goodbye, the girl asked if I’d had lunch.

After they left, I got into my Jeep and opened the paper bag.
