I'm sure many great people think about how they can make a difference in the world. In fact, sometimes little things can make a really big difference. I learned this 1 one day five years ago with my father, when I was just acting like myself—a nine-year-old kid.

    Papa came home late from work after 9 p.m. and he looked even more tired than usual. His eyes were already half-closed. I followed him to his bedroom. Papa 2 up the stairs, slowly lifting his feet one after the other. I was afraid that I would have to start pushing him. Fortunately, he 3 it to the bedroom on his own.

    Papa sat down on the bed and started removing his shoes and socks. "How was work?" I asked cheerfully.

    "Oh, it was OK," he replied. "It's just that I'm tired." "Oh, um……you want me to leave?"

    Papa gave me a tired 4 that made me more comfortable. I made me feel like he wasn't going to scold me, as he often did when I made some 5.

    "No," he said kindly, "of course I don't want you to leave."

    I opened my mouth and started 6 out the Disney movie Lilo & Stitch. Papa always loved it when I did that, and he started laughing loudly. I was happy that I had made my father laugh so much.

    "Did you like it?" I asked. "Of course I did," he said. "Did you know that 7you make me laugh, you make me feel a lot better?"

    I was  8that I could really do a thing like that.

①We usually think that garbage is dirty and useless. However, an art exhibition(展览) in 2022 proves that "useless" things can actually be helpful. 

②Dear Pretty Rubbish, an art event organized by the World Wide Fund for Nature (WWFN) and digital media art company Blackbow, was held in Beijing. It asked questions about the relationship between our lifestyles and our garbage. 

③"We hope that everyone who visited the show can think about how 'useless things' are produced, why they are tossed out and whether 'useless things' are really useless. " said Cao Yujia, the design director at Blackbow. 

④The organizers said that all the raw materials for the exhibition were collected from community garbage cans. 

⑤Artists Zhou Yuxuan and Liu Yifan collected nylon cable ties (尼龙扎带), LED lights and drink bottles from designers' workshops to create a work where plastics, in the shape of cells, "grow" in a corner. There, the lights blink (闪烁) to imitate (模仿) "breathing". When people walk near it, the work forms light patterns, as if communicating with the visitors. Speaking about the work, Zhou said, "It's like some kind of communication between humans and plastics. "

⑥Plastic has a life longer than almost any creature, taking centuries to break down. Though people blame plastics for damage (伤害) to the environment, they are a big part of our daily lives. 

⑦"So we want to ask the question: Although the damage continues, is there a way for humans to reconcile (和解) with plastics?" said Zhou. 

A student asked his teacher," Sir, I have a question. How many friends should a man have- one or many?"

" It is very easy," the teacher answered." Get me that red apple

from the highest(最高的) branch(树枝) of the tree." The student looked up and said," It's too high! I can't get it."

" Ask a friend to help." the teacher said.

 The student called a friend and stood on his shoulders(肩膀) for the branch.

"I still can't get it, sir," said the student sadly after the first try.

" Don't you have more friends?" the teacher smiled.

 The student asked more friends to come over. They stood on each other's shoulders, trying to make a pyramid(金字塔) to get higher. But the student still couldn't get the apple. Then one of the friends went home, brought a ladder(梯子) and the student finally picked the apple.

After getting the apple, the teacher asked," So, do you know how many friends a man needs?"

"I do," the student said." Many, so together we can work out any problem."

" Sounds good," the teacher said." You need as many friends as you can. Among (在…之中) them, there will be at least(至少) one clever man who can think of a good idea, like getting a ladder!"
