Galileo Galilei was born on February 15, 1564 in Pisa, on the west coast of Italy, to a Florentine family of noble families. Galileo's father was an aspiring man, fluent in Greek and Latin, and also quite accomplished in mathematics. As a result, Galileo received a good home-schooling from an early age.

Galileo Galilei (1564-1642) was a great Italian astronomer, mechanic, philosopher, physicist, and mathematician of the late Italian Renaissance. He is also a pioneer of modern experimental physics and is known as the "father of modern science". He is an indomitable fighter for the truth.

Engels called him "one of the giants who, despite any obstacles, was able to break with old theories and create new ones, regardless of any obstacles." He was born in Pisa on February 15, 1564 and died in Pisa on January 8, 1642. The Galileo family name was Galilei, and his full name was Galileo Galilei, but it is now common to call him by his first name, Galileo, rather than his last name.

Because of the translation problem, there are different opinions on the surname, and Galileo Galilei prevails.

Aristotle (384-322 BC), a native of Skitara, was one of the greatest philosophers, scientists, and educators in the ancient history of the world.

Aristotle was a student of Plato and a teacher of Alexander. In 335 BC, he founded a school in Athens called Lyceon, known as the School of Escape. Marx once called Aristotle the most learned figure among the ancient Greek philosophers, and Engels called him ancient.

My hometown is in Gangnam. The small river in my hometown is like a line of blood, which is spread on the body of Mother Earth.

The river is long, and there are many bridges. Bridges connect one village to another, connecting one family to another. If you carry a basket and go to the market, it will be strange if you don't go through eight or ten small bridges!

Most of the bridges in my hometown are stone bridges, but they have a variety of shapes. The simplest is the transfer bridge, a long stone slab rests at both ends, connecting the two households; The most beautiful, the most magnificent number of single-arch bridges, the bridge hole and its reflection image are a very big round cake, dozens of stone steps on both sides are embellished, forming a big "eight" figure, a pair of stone lions stand majestically on the stone pillar. At night, you hold a small boat to shuttle through it, and the scene will make you wonder if you have entered the house of Granny Moon!

The name of the hometown bridge is also beautiful. Chitose Bridge, Ruyi Bridge, Zhenlong Bridge, Yuanbao Bridge, Niangniang Bridge, Camel Bridge ......The adults told me that the Yuanbao Bridge and the Camel Bridge were called out by people according to their different shapes; The Zhenlong Bridge and Niangniang Bridge are related to folklore; As for the Ruyi Bridge, it is extracted from the poem of the Tang Dynasty poet Wang Wei: "If the flowing water is intentional, the twilight birds are returned".

Interestingly, the name of the bridge carved on the bluestone is also different, or seal or subordinate or Kai or grass, some are elegant and chic, some are strong and vigorous, and the bridge contrasts with each other, and adds a bit of interest. I remember one year, during the Qingming Festival, I took a boat with my grandmother to visit the tomb, and every time I crossed the bridge, I read the name of the bridge aloud, and then I listened to my grandmother tell a story about the bridge. Dozens of miles of waterways and hundreds of bridges, grandma's story is enough to fit a boat!

The bridge in our hometown is our paradise. Throughout the hot summer, we played chess and riddles at the bridgehead to tell stories; We use the bridge as a diving platform, compare diving skills, and practice courage; We fished by the bridge to touch the snails, and by chance, we even caught a pair of hairy crabs from the bridge hole! I'm really tired of playing, swing a boat into the bridge hole, stretch your limbs and lie flat, the cool wind, gently rippling water waves, in a blink of an eye, you will be sent to sleep ......

Memories of appearance, the bridge that remembers his hometown the most.

25."Reading for the Rise of China".

"Reading for the Rise of China".

When he was 12 years old, *** left his hometown and came to the Northeast. At that time, Northeast China was the focus of contention among the imperialist powers in China. He got out of the car in Shenyang, and his uncle, who came to pick him up, pointed to a prosperous and lively place, and said to him:

Don't go to that place if it's okay! ”

Why? *** asked puzzled.

It's a foreign concession, and it's bad if you get into trouble, and there's nowhere to make sense! ”

So why? "*** Break the casserole and ask in the end.

Why? China is sluggish! Uncle sighed and said nothing more.

Soon, *** entered Dongguan Model School to study. He never forgot what his uncle said when he picked him up, and often thought: "What is the concession like?"

Why can't Chinese go there while foreigners can live there? Isn't this the land of China......A series of questions puzzled ***, and curiosity drove him to see for himself.

On a sunny Sunday, *** broke into the concession with an uncle on his back and a good classmate. Hey! This area is really different from other places:

The streets are brightly lit and lively, and most of the people walking on both sides of the streets are yellow-haired, white-haired, big-nosed foreigners and patrolmen who show off their might.

Just as *** and his classmates were looking around, they suddenly found a group of people around the front of the patrol police station, shouting loudly. They hurried over, and saw a ragged woman crying in the crowd, and a large foreigner standing triumphantly. When asked, she found out that the woman's relatives had been run over by a foreigner's car, and she had hoped that the Chinese Patrol Police Bureau would support her and punish the foreigner.

Who knew that the Chinese patrol police not only did not punish the foreigner who caused the accident, but reprimanded her. The Chinese onlookers clenched their fists. But in a foreign concession, who would dare to do anything?

Only the unfortunate woman can be admonished. At this time, *** really realized the meaning of "China is sluggish" that my uncle said.

After returning from the concession, the students often saw *** alone pondering, and no one knew what he was thinking about while studying. It wasn't until in a self-cultivation class that I listened to ***'s speech that I solved this mystery.

In the self-cultivation class that day, Principal Wei asked the students a question: "May I ask what the students are studying?" ”

I sat there quietly all the time, not rushing to speak. Principal Wei noticed, gestured to calm everyone down, and asked him to answer by name. Stood up and replied clearly and firmly:

"Reading for the Rise of China".”

Principal Wei was shocked when he heard this! He never thought that a twelve or thirteen-year-old child would have such ambition and mind! He opened his eyes wide and asked again: "You repeat, what are you studying?" ”

"Reading for the Rise of China".”

The sonorous and powerful words won the applause of Principal Wei: "Wow! For the rise of China! Those who have aspirations should follow Zhou Sheng! ”

Yes, the young *** had already realized at that time that if the Chinese wanted to be free from imperialist bullying, they had to revitalize China. To read, this is the goal.

Comrade is the beloved prime minister of the people of all ethnic groups throughout the country. He devoted his life to the country and the people, and then died.

When he was a teenager, he was full of revolutionary ideals and was determined to study for the rejuvenation of China.

In the summer of 1910, at the age of 12, he followed his uncle to Fengtian in Northeast China and studied at Tieling Yingang Academy for half a year.

Later, he was transferred to the Fengtian Kanto Model School to study.

And studying", some said "to study for the glory of the ancestors", and another student said, "to help my father keep accounts."

Reading for the rise of China. It fully expresses the macro that young people should be angry and learn for the independence and prosperity of the motherland.

Great ambition. In October 1912, the Kanto Model School held a grand ceremony to commemorate the second anniversary of its founding. At the time, 14 years old ***.

I was so moved that I wrote an essay on the second anniversary of the Kanto Model School. He is in the text.

It is clearly written: "Students should take it as their responsibility to take on the "arduous responsibilities of the country in the future". This excellent essay was included in the book "Chinese Language Achievements of the Fengtian Education Exhibition".

Later, *** transferred to Tianjin Nankai Middle School to study. He and his classmates initiated the organization of the "Dedication and Happiness Club".

Taste the guts, dare to rest on the shoulders of moral struggle? It expressed his feelings of worrying about the country and the people and striving for strength, and expressed his determination to reform.

The noble ideal of life to the end.

In 1917, at the age of 19, in order to seek the truth of saving the country and the people, he traveled to Japan to study. Pro.

When he was leaving, he gave a poem to his classmates and wrote: "Dajiang Song turned his head to the east, and the rich and the rich helped the world." Facing the wall for ten years, it is difficult to reward the heroes of the sea. He expressed his determination to delve into the social sciences and save the country from peril, in the same way that the ancients did.

Ten years of hard work, to transform the society at that time, even if the ambition is difficult to pay, and the sea is dead, it is worthy of being in the middle.

The sons and daughters of Hua fully demonstrated the lofty ambitions of his youth.

This is a model of reading for the rise of China, in fact, the revolutionaries and scholars of that era probably have such a determination and sense of historical mission, but *** This sentence is a teenager's saying, it is well documented, and his life can better confirm this sentence. I think that in addition to reviewing history, such a speech needs to ask about the purpose of our learning today. For personal achievement, for the sake of family, for life is not wrong, but boys should have a sense of mission for the country and the nation, because the rise of the Chinese nation is a difficult and long process, which may take hundreds of years, and there is a long way to go.

Grade 4 Assignments:

Composition is the embodiment of a person's ability to understand things and express themselves in language and writing. We must be able to write down what we have seen, heard, felt and imagined clearly, so that the content is concrete, the feelings are real, the sentences are smooth, and the writing is neat. Be careful not to make typos and use common punctuation.

Develop the habit of paying attention, thinking carefully, being diligent in writing, and seriously revising your composition.

Whether it is a propositional essay, a semi-propositional essay, a free essay, etc., it is nothing more than writing about people, notes, activities, scenes, objects, pictures, expansions, abbreviations, rewriting, continuations, application essays, imaginative essays, etc. We can pay attention to writing a good essay from the following aspects:

1. Clarify the topic. Including the subject of the review (the writer?) Writing? Writing an event? Writing? ）；scope of review (time, place, quantity, person, etc.); Review the key points (grasp the key words of the topic, that is, the topic).

2 Clarify the center. One is that the title itself stipulates the center of the essay (e.g., "A Classmate Who Studied Assiduously"); The other is to only stipulate the scope of writing, what to write, and determine what center is up to you (remember the most impressive classmate of yourself).

3 Select the material. The material should reflect the central point of the article; The material should be authentic; The material should be representative and typical. The selection of materials takes several rounds and repeated thoughts.

You can first list the materials that can be used, and then choose the most expressive, specific and fresh materials according to the needs of the topic, and arrange the priority and details.

4 Tissue materials. This requires us to make an outline before writing an article, and clarify in what order to write, what to write first, then what to write, what to write last, how to divide paragraphs, and how to connect and transition; which ones are written in detail and which ones are abbreviated; How to start and end, etc., list them one by one, and the written article will be organized.

Of course, depending on the type of article, the specific requirements when writing are also different. For example, when writing about people, they should grasp the events to write, write about the appearance, language, behavior and mental activities of the characters, and write specific details that can express the characteristics of the characters. In the composition of the memorization, the cause, process, and result of the event should be clearly written, and the main part of the matter should be written specifically and appropriately.

The key to writing an article about an event is to write a few scenes from the event. The writing of scenery should be in a certain order, and the characteristics of the scenery should be written concretely, vividly, and vividly, and the scenery should be used to express lyricism. The key to looking at pictures and writing is to see the meaning of the picture clearly and imagine reasonably.

The key to imagination composition is to imagine boldly, which is not only imagination and fantasy, but also has meaning to reality, expressing one's own ideals and pursuits. Practical essays need to master a certain format, clarify the purpose of writing, and so on.

Find the central sentence and talk about it in a nutshell.

The fish swam to the paper.

There are many places to watch fish in West Lake. I like the flower port, and I prefer the jade spring where the "spring is as white as jade".

The water in the Yuquan pond is crystal clear. Sitting in the tea room by the pool, brewing a pot of tea, leaning against the railing and watching the fish swim freely is really pleasing to the eye. There are more than a dozen tanks of goldfish in the backyard of the tea room, and there are many fish lovers gathered there

There are old people, there are children, and there are young people.

It was by the goldfish bowl that I met a young man with a peculiar manners. He was tall and delicate, with a pair of big eyes as bright as the water of a jade spring.

When I say "know", I don't know him, but I've only met him a few times. He is said to be "special" because he loves fish to the point of selflessness. He always stood alone by the goldfish tank, quietly watching the goldfish swim in the water, and never said a word.

One Sunday, I arrived at Yuquan a little later than usual. The goldfish bowl was already crowded with people, most of them innocent and lively children. The children were dressed in bright clothes, as if they were more beautiful than goldfish.

Yo, the goldfish has swam to his paper! A girl cried out in amazement.

I squeezed over to take a look, and it turned out to be the young man who was quietly drawing. He sometimes drew every part of the goldfish meticulously, as meticulously as a girl embroidered a flower; Sometimes, he sketches with a stroke of his pen, and quickly draws the dynamics of the goldfish, as if the goldfish is swimming on paper.

There were more and more onlookers, everyone admired and discussed, and the only one who didn't react was himself. He seems to have become one with the swimming fish.

I still went to the tea-room to drink tea, and when the sun was almost down, I got up and walked back, and when I passed by the backyard, I saw the young man still painting by the goldfish bowl. He seems to have lost track of time, and he has forgotten himself.

You're so attentive! I couldn't help but ask him softly. I didn't expect him to raise his head or ignore me.

What a proud young man. I was thinking about it, when my eyes fell on the factory emblem on his chest, and my heart couldn't help but chuckle! "Welfare factory", it turned out, he was deaf and dumb!

We started talking with a pen on paper. He told me that he had only been studying painting for more than a year, and in order to paint goldfish, he came to Yuquan every Sunday, and he looked at it all day, often forgetting to eat and go home.

I wrote to him what the girl had said: "The fish has swam to your paper!" ”

He smiled, so sweetly. He took the pen and added another sentence on the paper: "First it swims to my heart." ”
