The world is full of amazing things. Today, I'm going to talk about something amazing. We have lots of things to do every day, so many of us will be tired after a busy day.

Holding doors open, picking up rubbish, thanking people ... these acts of kindness seem very small. But students at Tibbett Middle School know that it's the small acts that make the world a better place. Eighth-graders from New Mexico, US, took part in the Random Acts of Kindness Week from Feb 10 to 14. During the week, they tried their best to do kind things for others, or for the environment. Celeste Murray, an English teacher at the school, started the activity. "I believe the world is changed by little things," she told the local newspaper. Over the week, Murray said she has seen changes in her class. Previously, she asked her students to push the chairs in after class. Now, the students do it by themselves. "The teachers will have less work," said Elisa Castaneda, one of Murray's students. Jordan Marshall, another eighth-grader, spent the week giving out praise . "It makes that person's day ," she said. "Besides helping others, the activity made students feel that they can make a difference," Murray said. Eighth-grader Haley Echols decided to continue to do at least one act of kindness every week. She believes her acts could encourage others. Elisa thinks if students push in chairs after class, _ . A) teachers' work can be reduced B) the environment will be better C) other students' time can be saved D) no rubbish will be left

It was the Greek shopkeeper who taught me about the power of being kind. In 2008, I left Spain to study alone in London. My parents had to bring up my three younger sisters and two younger brothers, so I found three part-time jobs to pay for my studies. I worked early mornings and late nights, so I was tired, really tired, all the time. Unluckily, I got a cold and had a very high fever. Because I was new in London, I had no friends. Besides, I was too shy to talk with others and ask others for help. After sleeping on the bed for two days, I went out to get some food. Usually, I went to the supermarket, but this time I went into the Greek shop, a small corner shop, because it was closer. I picked up some food and gave it to the shopkeeper, who asked me, 'You look terrible, my boy! You are not feeling well, right?' I said YES in a low voice. She pointed at the salami and bread I was buying and offered, 'I can make you a sandwich, so you don't have to do it yourself.' I nodded without saying a word. So, she made the sandwich and asked me to wait a moment. She went into the back room and came again with a bowl of hot soup. 'It will warm you up,' she said with a friendly smile. What really warmed me up was not the soup. It was her smile that told me she cared me. Her kindness made me think of my mother. I was quite shy, but from that day on, I did not let shyness stop me from talking with and being kind to others. Now I work in a children's hospital in Africa. I love my work and people around me. I always bring my smile and kindness to them. Which of the following words can't describe the Greek shopkeeper? A) Friendly. B) Shy. C) Nice. D) Kind.
