Dear teachers and students:
Hello everyone!
Not long ago, I read a fairy tale, The Giant's Garden, written by the British writer Wilde. This story is about a giant who was angry when he saw children playing in his garden. He built a high wall around the garden to keep the children out. Since then, the garden has been deserted, with flowers blooming and birds singing silently. It refuses to come in spring, summer and autumn, and only stays here forever in winter. One day, the children climbed in from the hole in the wall, and spring followed them, and the garden immediately became full of vitality. When he drove the children out of the garden again, the garden was covered with snow and ice. Later, inspired by the little boy, the giant woke up and immediately pulled down the wall, and the garden became a paradise for children. The giant lives among the beautiful gardens and children and feels very happy. ...
Oscar Wilde's happy story has disturbed my heart for a long time. The giant's two selfishness and ruthlessness brought the winter of ice and snow to the garden, which made the children lose their joy, and he was lonely and didn't enjoy the beautiful scenery in the garden! We often say, "Give someone a rose, and your hand will smell fragrant". In fact, happiness is the same. Give others happiness and you will be happy.
I still remember this famous saying: "share your pain with others, and your pain will be reduced by half;" Share your happiness with others, and your happiness will double. "Yes, sharing happiness won't cost you anything, but it can make the world warm. On the contrary, with happiness, a person will be happy and will not be happy in the end.
Sharing happiness with others is a virtue, because happiness is contagious. In fact, many times, sharing happiness with others not only gives others a chance, but also gives themselves a chance; Not only gave others a good mood, but also left a good mood. In this case, please open your heart and sincerely share with others-you are a fire, so you must try to light others; If you are a basin of water, you must try to wash others; If you are a grain of rice, you must try to grow bigger ears of rice; If you are a crescent moon, you should try your best to send light to the night walkers ... You will be happier if you are happy with others!

Dear teachers and students:
Hello everyone!
Confucius in the Spring and Autumn Period was a great thinker, politician and educator in China, and was regarded as the most learned "saint". Why did Confucius have such profound knowledge? The story of Master Confucius in the textbook of Chinese studies tells us that in our daily life, there are people everywhere who are our teachers, and we should ask questions with an open mind like Confucius.
I remember one day when I was in kindergarten, I saw my parents playing chess. One moment my father won, and the next my mother won. I was curious and asked them what they were playing. Dad told me that it was called gobang, and whoever arranged five pieces in a straight line first won. So I asked my father to teach me chess. From losing at the beginning to winning one or two games occasionally, I gradually mastered the game of gobang. Now, my mother and I are neck and neck at chess, and often all the pieces are finished, so we can't decide the outcome. Father praised me as a "chess player"
You see, there is always something in life that you don't understand, so you must ask. Please don't let vanity block your mouth. To block your mouth is to block the door of knowledge. "Sensitive and eager to learn, not ashamed to ask questions", with the open-minded spirit of life, will benefit for life.

Dear teachers and students:
Hello everyone!
The topic of my speech today is "If you want to succeed, you must persist".
First of all, I want to share an interesting story with you: I remember that once, the great philosopher Socrates said to the students, "Today, we only learn the simplest and easiest thing: everyone puts his arm forward as far as possible." Socrates said and demonstrated it again. "Starting today, do it 300 times a day. Can everyone do it? " The students all laughed. What can't be done with such a simple thing! After a month, Socrates asked the students, "Who insists on throwing 300 times a day?" 90% of the students raised their hands proudly. After another month, Socrates asked again:
This time, only 80% of the students persisted. A year later, Socrates asked everyone again, "Please tell me, who else insisted on doing the simplest cutting exercise?" At this time, only one person in the whole classroom raised his hand. This student is Plato who later became another great philosopher in ancient Greece. The profound meaning contained in this short story is obvious.
Buffon, a great French enlightenment thinker, once said, "Genius is long-term perseverance." China mathematician Hua once said: "Learning and research must be persevered." Indeed, unremitting efforts and perseverance are essential to success in what we do. There are many such examples at all times and in all countries. Balzac works hard for 16 or 17 hours every day. Even though his arms are sore and his eyes are watery, he refuses to waste a moment. This is why he can finish a masterpiece. What is his inspiration to us? I think he has injected a strong spiritual power into each of us, that is, clear goals, perseverance, and ultimately success! The easiest thing in the world is persistence, and the most difficult thing is persistence. This is easy, because everyone can do it as long as they are willing to do it; This is difficult, because only a few people can really do it.
Persistence is a belief, persistence is a quality, and persistence is a noble quality.
Now some of our students cheat in exams for short-term benefits without making long-term plans. This practice does not conform to the spirit of Xinhai High School, which not only shames the school and teachers, but also loses the opportunity to test themselves. Losing this opportunity is tantamount to giving up on yourself and ultimately achieving nothing.
Success and failure are often only one step away. If you want to succeed, you must persist. This is a secret that is not mysterious. But it is sad to persist in diligence and choose the wrong direction. "Diligence" has no value as long as it exists. Deviated from the right direction, the direction is wrong. It's just that an express train has derailed. Whether it's sweat, tears or blood, the end point is "out of reach". If we beautify persistence as a sorcerer's stone, we think that no matter what kind of decay is touched by it, it will become magical. In fact, it is like turning a stone into a brocade and beating a bunch of silk threads into beautiful jade. Maybe the strength and method are suitable, but the wrong object is chosen.
When difficulties hinder your success; When failure dampens your enterprise; When you are overwhelmed, don't back down, don't give up, you must stick to it, because only persistence can lead to success!

Dear teachers and students:
Hello everyone!
Today is the time for my speech, three minutes before class. Three years before the birth of Christ, there was a great politician and orator in ancient Greece. He is a real pervert. If you don't believe me, please allow me to introduce you one by one with his real experience!
Demosthenes was born with a weak voice, lisping and panting. (As you can imagine, he is really poor! ) especially the letter "r", he can't speak clearly, and his pronunciation is worse than that of a child who just learned to speak!
It is said that in order to overcome these defects of lips and teeth, he has been practicing pronunciation with stones in his mouth. He stood by the sea and practiced, trying to calm the rough waves. Do you think he is abnormal?
When he stood on the stage and spoke to the audience, he experienced countless failures, especially when he tried to speak for the first time. His words were all confused and the audience laughed loudly. In order to improve his speaking ability, he deliberately dug a hole, practiced his voice and speaking posture in it every day, and shaved half his hair to control his desire to go out on the street. Demosthenes's persistence finally paid off, and he became one of the greatest orators in ancient Greece.
This story tells us that a person's shortcomings are sometimes hints of success information given by God. A person's weakness can be an incentive factor in his life, and it can also be an excuse for your depression and timidity. When Demos had pebbles in his ruler, when he was at the seaside and in the cave, he must still be thinking, I want to be abnormal! I want to go beyond normal. Decades later, he will say, "How can such a pervert not succeed? !
Edison experienced 1 10,000 failures in the process of inventing the light bulb. The Coca-Cola Company sold 400 bottles of Coca-Cola in its first year of operation. Walter Disney, the founder of Disneyland, was fired for "lack of creativity" while working in a newspaper. Superstar Jordan was removed from his middle school basketball team; River Johnson, the decathlon champion, has a congenital deformity of one foot.
When they achieve great things, they will definitely say: How can such a pervert not succeed? !

Dear teachers and students:
Hello everyone!
In the process of growing up, everyone has experienced joys and sorrows, ups and downs. Of course, I am no exception. Some make me laugh, others make me unforgettable. ...
It turns out that we can also hide the fun of childhood in our hearts, record it with a pen, or share it with you. Today, I will tell you a little math story when I was a child.
This is a sunny weekend. In the early morning, I finished my homework assigned by the school and sat there watching TV with nothing to do. Seeing that I was not studying, my mother gave me a task-helping her buy food.
As soon as I heard this, I suddenly became nervous and didn't know if I could finish the task. I say this because I have never been to the vegetable market alone, let alone buy food, but I thought that if I could share something with my mother today, I might get praise from my parents and exercise me, so I had to bite the bullet and promise my mother. I took the 30 yuan cash my mother gave me and went to a side dish market not far from my home. Although the vegetable market is small, it sells a lot of things. At first, I was so nervous that I didn't even have the courage to say hello to others But careful observation shows that it is not so difficult, and the courage is getting bigger and bigger. So I'm going to buy my favorite chicken leg. The original price was one from 3 yuan, but the boss thought I was a child, so he said to give you a special price of two from 5 yuan, 1 yuan. As soon as I heard it, it was quite cost-effective. I said, "Good.
Hearing this, the boss nodded and took two warm chicken legs. After I gave him 10 yuan, he left. He went to the vegetable area to buy a catty of vegetables, spent 3 yuan, bought a catty of mushrooms for 5 yuan, and bought two jins of edamame for 6 yuan, but after buying them, he always felt that the money in his hand was wrong. After calculation, he really lacks 5 yuan. Think about it. By the way, he forgot it the first time. I'm still a little embarrassed to buy chicken legs here. The boss saw me and said, "I called you just now, but you didn't hear me." Be careful next time. " I nodded and said thank you. When I got home, I gave my mother the rest of the change and told her how much these dishes cost. My mother was very happy when she saw two dishes in my left hand and two dishes in my right hand. She also told my father that I could help her when I grew up. But she knew from there that I almost made a mistake.
