I went to a group activity, “Sensitivity Sunday” which was to make us more1the problem faced by disabled people, We were asked to “ 2a disability” for several hours one Sunday. Some members 3chose the wheel chair, Others wore sound-blocking earplugs(耳塞)or blindfolds .

    Just sitting in the wheelchair was a4experience, I had never considered before how5 it would be to use one .As soon as I sat down my6 made the chair begin to roll ,Its wheel were not7Then I wondered where to put my 8.It took me quite a while to get the metal footrest into 9 ,I took my first uneasy look at what was to be my only means of10for several hours, For disabled people, Using a wheelchair is not a temporary(临时的) 11 

    I tried to find a12position and thought it might be at ease, 13a little nice to be 14around for a while. Looking around, I 15 I would have to handle the thing myself! My hands started to ache as I 16the heavy wheels, I came to know that controlling the 17 of the wheelchair was not going to be a (an)18task.

    My wheelchair experiment was soon 19. It made a deep impression on me. A few hours of “disability” gave me only a taste of the 20 , both physical and mental, that disabled people must overcome.

    When I first entered university, my aunt, who is an English professor, gave me a new English dictionary. I was 1 to see that it was an English-English dictionary, also known as a monolingual (只用一种语言的) dictionary. 2 it was a dictionary intended for non-native learners, none of my classmates had one 3, to be honest, I found it extremely 4 to use at first. I would look up words in the dictionary and5 not fully understand the meanings. I was used to the 6 bilingual dictionaries, in which the words are 7 both in English and Chinese. I really wondered why my aunt gave me such 8 to make things so difficult for me. Now, after studying English at university for three years, I 9 that monolingual dictionaries are 10in learning a foreign language.

    As I found out, there is, 11, often no perfect equivalence (对应) between two 12 in two languages. My aunt even goes so far as to 13 that a Chinese “equivalent” can never give you the 14 meaning of a word in English! 15 she insisted that I read the definition (释义) of a word in a monolingual dictionary when I wanted to get a better 16 of its meaning. 17, I have come to see what she meant.

    Using a monolingual dictionary for learners has helped me in another important way. This dictionary uses a(n) 18 number of words, around 2,000, in its definitions. When I read these definitions, I am19 exposed to the basic words and learn how they are used to explain objects and ideas. 20 this, I can express myself more easily in English.

    My car needed some mechanical work that I could not do myself. Since the garage I had been taking my car to had 1, my friend Dave gave me a recommendation: D's Auto Repair.

    I was pleasantly 2 to discover that the owner of D's was a mechanic who had worked on my car several years earlier. 3 he was an employee at a gas station near my house. I knew that his work was good.

    I 4 the paperwork for the repair and 5 while D took a phone call from another customer. As I sat there, I looked around the small office to keep myself 6 A framed newspaper article caught my attention. The headline 7: "Local Dairy Farmer Kills Whole Herd.” The article was about the 8 of a fifth-generation dairy farmer during the polluted milk scare in Michigan several years earlier. Dairy cows were becoming 9 a disease that was affecting the milk supply. The fifth-generation dairy farmer paid to have all of his cows 10. It was found that out of the entire herd, only a few were were infected. Because no one could 11 that the other cows were totally 12, he had the herd killed and buried to make consumers feel rest assured(放心). The farmer's insurance did not cover his 13 because the state had not issued a(n) 14 for him to get rid of the herd. Asked why he did it, the farmer replied "Because it was the right thing to do.

    I asked D why he 15 the article on the wall. I thought that he might be related to or 16 knew the farmer. He said he had never met the man, but that the farmer was a(n) 17 to him and set a standard for integrity(正直), trust and honesty. He said that is how he 18 his auto Repair business.

    I was now doubly 19 by both the farmer and D. The next year, 20 my recommendation, my son started a nine-month mechanics apprenticeship(学徒) at D's Auto repair.

    You never know how far a kind act can go. You don't know who it can 1, either. When Gloria Porter and Jeff Reick began 2, they had no idea how much it would 3 others to shower (大量给予) people with kindness.

    89-year-old Gloria Porter was lying in hospital. She couldn't leave her ward. So to 4 boredom, she would often stare outside her window to watch construction workers building the new front entrance to the hospital. She wasn't expecting one of the 5 to wave to her. She couldn't help but wave back at the kind 6. This was only the start of a special 7 between the two.

    Jeff Reick knew Porter was 8, so he decided to send a kind 9 to her by finding some chalk and writing "Get Well" on one of the beams (梁) facing her 10. "I just thought that was 11," Porter said. "So I should do something to 12 that."

    When Porter saw construction workers working high above the ground one cold, windy day, she grew 13. She wrote "Stay safe" on a piece of paper, which she then 14 on the window for the workers to see. "When I saw 4 Stay safe' on a piece of paper, I 15 and said to my coworkers, 'Did you see that?'" Reick said.

    The hospital staff took photos of that and 16 them on social media. The simple acts of kindness 17 and many people were employed in similar acts, including one woman who delivered 18 pizza to the construction workers.

    "I just try to lead by example and never expect so much 19," Reick said. "If everybody 20 does things like that, the world will be a better place."

    Yuan Longping, a great Chinese agriculturalist, was born in a poor farmer's family in Qianyang, Hunan Province in 1930. He 1 from Southwest Agriculture College in 1953 and has since devoted himself to agricultural education and research. Since his graduation, 2 ways to grow more rice has been his life goal. As a young man, he saw the great need for 3 the rice output. At that time, hunger was a 4 problem in many parts of the countryside. Yuan Longping searched for a way to increase rice harvests without expanding the area of the fields. 5 his help, Chinese farmers now produce more rice and these increased harvests mean that 22% of the world's people 6 from just 7% of the farmland in the world. Yuan Longping, 7 considers himself a farmer, is now circulating his knowledge in some less developed countries to increase 8 rice harvests. Thanks to his research, the UN has more tools in the battle to rid the world of hunger. 9 his hybrid rice, farmers are producing harvests twice as large as before. Dr Yuan 10 5-million-yuan State Supreme Science and Technology Prize for his high hybrid rice species. This award is viewed as "Chinese Nobel Prize".

    About rice, he always has a dream…

Pooja Rai was a young architecture student in 2014 when she went with a friend to give food to a local orphanage. She was surprised at what she saw.

Kids were playing with anything they could get their hands on. One group was rolling around a broken metal pipe. Two boys were trying to play badminton, using old shoes as rackets. "Play shouldn't just be part of a rich kid's lifestyle. All kids have a right to enjoy their childhoods." Rai says.

Over the next few weeks, she talked with friends about collecting money for a playground. And that's when she thought of old tires. Around 100 million tires are thrown away in India every year. Could they reuse them as playground materials and help the environment, too?

That idea became a reality in 2015, using old tires—all cleaned, carefully looked over to make sure they are safe to use, and painted in bright colors. The following year, she created Anthill Creations, which has built 275 playgrounds across India —celebrating the power of play in public spaces. orphanages, and schools.

"Our work always begins with talks with kids about what they want from this space." says Rai. Sometimes it can take a few hours, or a few visits, until children are ready to open up. She also draws on her experience as an architect. "I found that spaces are powerful in shaping people's behavior." she says.

Most of the play spaces Rai designs feature large tire sculptures of cars, buildings, or animals, paired with more classic elements of swings and jungle gyms.

In one girl's school in Bengaluru, the children wanted their play space to be shaped into a boxing ring, with tires doubling up as punching bags. "Their teacher was unsure about it." Rai remembers. "But the girls said they didn't want people to see them as weak. They wanted to practice self-defense and grow stronger." In December 2019, this playground became a reality.
