Write a composition.

(1) Twenty years ago, there were 505 classes in Longping Primary School and 58 boys and girls grew up together.

Twenty years later, on May Day, old classmates got together to greet the hotel and say goodbye.

At nine o'clock in the morning, the students greeted each other and talked in the conference room. The atmosphere is very warm. Judging from the conversation, most people have cars, houses and children, some people have stood up, and some people still keep their original figure. Interestingly, most girls are still young and beautiful, but boys have shown the appearance of middle age.

The students have changed so much. Liang Yuya, the best girl in her former class, is now the host of CCTV's legal report, and her glorious image often appears on TV. Zhang Jiehui, an old monitor, is now a section chief of the Municipal Public Security Bureau, contributing to people's peace; Zheng Haoru, a representative of the English Department, worked as a translator in the Ministry of Foreign Affairs, traveled around the world and made a splash. Liu Yaoda, the youngest, is now the boss of a company in Shenzhen, with an annual salary of more than 200 thousand; And my best friend Huang, now the president of an internet company in Hong Kong, with an annual salary of more than 300 thousand; Li, the most stable student at that time, is now a professor at East China Normal University in Shanghai. My deskmate Yang Huimin is already the director of Guangzhou Women's Federation; Everyone thinks I'm the most incredible. After successfully taking the national judicial examination, the iron rice bowl civil servants turned to the profession of lawyer. In fact, I think it is more challenging to safeguard the dignity of the law and the rights of victims! Surprisingly, the organizer of this gathering was Huang Yiting, who was honest in those days, and now she is the deputy mayor of Meizhou. Who would have thought that she was so active and full of organizational skills today? Our class is full of talents, winning glory for Longping Primary School!

After lunch, we took a luxury cruise, swam in the lovely mother river and enjoyed the beautiful scenery on both sides of Meijiang River. There are songs and laughter one after another, and the friendship of classmates overflows the cruise ship.

In these twenty years, how many stories, endless topics and endless friendships have happened to us, and we can't bear to leave after dinner until it is getting late!

(2) Suddenly, one day, a very big news came out from the scientific community. Newspapers all over the country published this amazing news on the front page: The Institute of Cosmology built a 20-story building called "Gemstone Building" in just eight hours.

As a reporter of the new journal, I certainly can't be idle. I took a special plane interview and brought a pair of special glasses with automatic recording function based on the principle of Edison's phonograph. This special tool is very convenient for news interview. Soon, the destination arrived. I let the plane spiral down from the top of the gem building. Through the glass window, I saw the top of the gem building, surrounded by a blue cloud, with a hill like a power plant in the middle. I am glad that the creator made full use of the principle of solar energy to make the roof.

The plane circled slowly around the building. I, eureka tower, was a thick and long cylinder, just like a big chimney. I was amazed by the designer's meticulous conception. In the hangar, I enjoyed the exterior wall of the building. It is all inlaid with a luminous decorative material, as elegant as a palace. No wonder it was named "Gem House".

When the plane approached the bottom of the building, I left my seat and stood at the door of the hangar. I am anxious to find the door. I saw the pilot point a lighter or something at the wall, and one wall of the building was lifted. A woman in a dress stood at the door to meet me. Before the plane stopped, the woman ran over, hugged me and whispered, "Quiet, I guess it must be you, big reporter, I didn't expect it." "Oh," non-success "I didn't say hello to you, just to give you a surprise. I'm here to see you, a great inventor. "

"Yunyun" took me into the building. I pointed to the wall and said, "The interior of the building is decorated with plastic plates." Before I finished, Yunyun shook his head and said with a smile, "No, no, you are wrong. No decoration outside the building, no decoration inside the building. It is a light, colorless, pollution-free and nonflammable decorative material developed by me in recent 20 years. With that, she took out a very beautiful little box from her pocket and handed it to me. When I opened it, I found a jewel-like thing, which was dazzling. I kept nodding and saying, "Cloud", you are really good! This invention fills a gap in the world's decorative materials. Unexpectedly, the little girl who was unknown in those days has become a great inventor today. It's amazing! "

After a short meeting, I can't help but admire: Yes! Chopin said it well ―― A wise man will not wait for opportunities, but will strive for them, make use of them and make them his slaves.

Twenty years later, I:

(1) Twenty years later, I am an expert in flower planting. In order to make the flowers in the garden bloom brilliantly and delicately, I tried my best, but my hard work was not in vain, in exchange for a bunch of admiring eyes and happy smiling faces.

One day, my neighbor Mrs. Ruth bought a batch of new roses, and I went to her house to look after them. This new kind of rose stands out from the crowd: it looks a bit like a star from a distance and a bit like the sun from a close look. It is golden, and it shines with dew in the morning. Really beautiful! I was deeply attracted by this beautiful flower and couldn't take my eyes off it. I wish I had this beautiful flower! But I know it's hard to find. Other people's things can't be yours.

Once, Uncle Burton bought a lot of black chrysanthemums and invited me to his house to enjoy the flowers. Walking into the garden, I felt as if I were in layers of black waves, like a silent girl's curly hair. How beautiful! I went to the flower and observed it carefully. I found that the only fly in the ointment was that the black chrysanthemum lacked natural luster and its leaves were a little sunken. I think: this black chrysanthemum must be short of water and fertilizer, and I must protect it. So, I picked up the watering can and gently sprinkled water on the flowers. The leaves absorbed water, raised their heads proudly and smiled gratefully at me. I brought fertilizer to fertilize the flowers. After a few days, the black chrysanthemum showed natural luster and reappeared beautiful colors. I jumped with excitement! This is me, an observant, diligent and selfless person.

In the 2026 China Expo, an oversized peony flower was displayed. This peony flower is more than 10 square meters in size, and there are hundreds of peony flowers: red, yellow, blue, green, purple and brown ... each flower is as big as a washbasin and exudes attractive fragrance. It's amazing! This is a new variety I cultivated. For it, I forgot to eat and sleep, read many books on flower planting, consulted dozens of experienced teachers, studied the growth process of thousands of flowers in the world, and cultivated them with the latest grafting technology, the most suitable sunshine, the most suitable humidity, the most suitable temperature and the most suitable fertilizer. This is me, who loves thinking, is not afraid of difficulties, dares to accept challenges and climbs the peak of science forever.

This is me 20 years later. In my ordinary post, I am brave and upright, able to withstand the temptation, good at observation, careful and hardworking, selfless dedication, love to use my brain, not afraid of difficulties, dare to accept challenges, climb the peak of science forever, surpass myself in the ordinary and achieve impressive results!

Time flies, the sun and the moon fly like a shuttle. In a flash, 20 years have passed and I have grown up. Looking back at my alma mater, I can't help but miss it deeply. I really want to go back and see it.

Do it. I had nothing to do this afternoon, so I went to my alma mater. When I came to the door, I looked, hey, why are there no robot guards? After that, the door opened automatically. Strange, how can it open automatically? Do you know me? This is, when Teacher Lu came over, I asked her. She told me, "This is because there is a hidden monitor above the door, which can tell whether you are a good person or a bad person. So even if there are no robot guards, there will be no bad people entering our school, and the school will feel safe. It suddenly dawned on me, so that's it. I can't help but admire: my alma mater has changed a lot.

At some point, we came to the classroom. I looked inside. Hey, why are there no students? It turns out that all students are invisible in class, because in this way, classes can be as interesting as watching movies, and they can also learn knowledge. This kind of movie-like learning is very popular with students, so all students love learning and their academic performance is among the best.

After that, I came to the playground. What I saw was a very beautiful garden with many flowers and trees, like an ocean, which made people feel relaxed and happy. I am intoxicated with it. After a while, I came to my senses and asked Teacher Lu, "Now the grass playground has become a garden. What should students do in class? " Teacher Lu didn't answer. He took me to the place where I sat on the flying carpet and took the flying carpet to the top of the school. I asked curiously, "What did you bring me here for?" Teacher Lu still did not answer. She pushed me forward, and I walked in, and suddenly it was like walking into another world. I saw the grassy playground, but there were still no students. I saw teacher Lu press the "playground" button and the playground came out. Besides, many students are having a good time. I asked the teacher, "Why didn't you see the students just now?" "Because what you just saw is an imaginary playground, the real playground will only appear when you press the button. There are also many buttons here. The playground is just a place where students do morning exercises and have classes. Press "football field" if you want to play football, and press "basketball court" if you want to play basketball. Teacher Lu proudly said to me. After listening to this, I nodded and couldn't help admiring: "The alma mater is really great and developing too fast. China's economy is amazing! "

Yes, China's economy is developing rapidly. As long as we study hard, we will certainly create more and better societies in the future!
