Lily loved school. However, there was one class Lily worried about more than any other—art. She didn't know why she just wasn't any good at drawing, painting, or cutting.

Ms. Clay, the art teacher, stood at the front of the room. "Class, next Friday our school is going to have an art competition," she announced. Ms. Clay was a great teacher, and Lily liked her a lot. But this announcement made Lily nervous. "Everyone in the school will create a piece of artwork to show in the library. You can use the different types of artwork we have been studying." Ms. Clay was quite excited when she spoke while Lily found herself sinking lower in her chair.

Lily had the whole weekend to work on her project, but she could not think of anything to do. On Monday, Lily felt frightened, so after school Lily asked Ms. Clay if she could write an art paper instead of doing an art project.

"I understand this project scared you, Lily," Ms. Clay said. "Just remember, you can create any kind of art you want." Ms. Clay smiled at her. "Art is a person's way of expressing his or her feelings—it isn't always painting, drawing, or cutting. I know you will think of something very creative, and I can't wait to see it."

When Lily arrived home, she took out a piece of paper and a pencil. She remembered Ms. Clay's words. "Art is a person's way of expressing his or her feelings." Lily wrote the word "terrified" on her paper. She crumpled (揉皱) the paper and threw it to the side of her desk.

Then Lily stared at the crumpled ball. Suddenly an idea struck her.

Paragraph 1：

Why not create something out of crumpled paper?

Paragraph 2：

On Friday, Lily carefully carried her project into the library.

One teacher had two students. One of them had a positive vision while the other had the 1 one.

One day, the teacher 2 for a park with both the students and while wandering in the garden, they 3 a mango tree from which some ripe and juicy mangoes were 4 . On seeing this, the teacher thought to 5 both of his students. Then, he asked the first one, "My dear child, what do you think of this mango tree?"

The student answered instantly, "Teacher, in spite of people 6 this tree with stones, it gives us sweet and juicy mangoes. It does 7 but still it gives us fruits. I wish all human beings learn this important 8 from the mango tree-to share their 9 even if they have to suffer for this."

After that, the teacher asked the other student the same question. The student 10 answered, "Teacher, this mango tree is no good and will not give mangoes by itself but only when we hit it with stones and 11 . Therefore, we should hit it hard to get sweet mangoes from it. That is the only way to 12 these mangoes. It is also clear from this tree that in order to get good 13 from others, we need to be violent and only when we become violent, then and only then will we get 14 ."

The teacher was delighted with the answer given by the first student because he had an admirable vision and 15 the tree with positive vision.

Rebecka Peterson, a high school math teacher, is the nation's 2023 Teacher of the Year. Her first year of teaching wasn't without its 1 ，but she remembered why she was there and wanted to bear those2 thoughts in mind. So she 3 the One Good Thing blog.

It was 4 and fun, really. Every evening, she would write on her blog, 5 "one good thing she experienced that day. She gave her blog the tagline; "Every day may not be good, but there is on good thing in every day."

She encouraged her 6 to do the same in their handwritten journals. Just a few minutes a day to7 something good that happened—that would be enough, she 8 . She believes that it will make them happier and more 9 to learn.

During her eleven years in teaching, Peterson has10 that some students find math difficult. But her efforts to make it 11 made her the 2023 Oklahoma Teacher of the Year. From there, she made the 12 to win the nation's 2023 Teacher of the Year.

Peterson has travelled around the country, talking to teaches about binging 13 back to Classrooms. Her goals include emphasizing the positive experiences students have not only with math but with learning 14 . She hopes her stories will attract new teachers to the profession and give 15 to current ones.

 "BANG!" I pulled the door heavily behind me. "Never set foot in this house again!" stormed father. I rushed out of the flat and ran along the street.

A young man who held a child in his arms walked past me. I felt as if I saw my childhood from another space: happy and carefree. But now...I don't know whether it is because I have grown up or because Dad is getting old. We differ in our ways of thinking. We are just like two people coming from two different worlds. It feels like there is an iron(铁制的) door between us that can never be opened.

I wandered in the streets, until I had only the street lights to keep me company. My heart was frozen on this hot summer night. When I finally reached the high-rise apartment block in which I lived, I saw that the light was still on.

I thought to myself, "Is Father waiting for his boy, or still angry with him?"

All the lights were off except Father's.

Dad was always like this. Maybe he didn't know how to express himself. After an argument he had the habit of tucking me underneath the covers(掖被子) while I was sleeping. This was how he always was. He had been a leader for so long that telling everyone else what to do had become his second nature.

The light was still on.

"Am I wrong?" I whispered, maybe... With the key in hand, I was as nervous as I had ever been. At last, I decided to open the door. As soon as I opened the door, tears ran down my cheeks. I suddenly realized that the iron door that I had imagined between us did not exist at all. Love——it's second to none.
