Ye Shengtao, a famous educator, once said: "Life is like a source, and language is like a stream. The source is abundant and inexhaustible, and the stream flows naturally and lively. "

Continuous autumn rain, such as thread cutting. Looking at the drizzle in front of me, I fell into deep meditation: I almost racked my brains because I was trapped by a "roadblock", but I still couldn't figure it out. Just when I was dizzy and secretive, flying thoughts quietly reminded me of endless memories.

A few days ago, we just finished learning morton hunt's "Take One Step, Take Another Step", in which "I" was always sick. After climbing the narrow ledge two-thirds away from the cliff top, I was "scared" and "almost fainted" and dared not climb any more.

Finally, under the guidance and advice of my father, I bravely survived the difficulties. Thinking of this, I can't help but sigh from the heart: Yes! On the road of life, no matter what difficulties and obstacles you face, as long as you divide the big difficulties into small ones and solve them one by one, you will eventually overcome the huge difficulties and win the final victory.

Moreover, when Cao Xueqin was frustrated, I thought of A Dream of Red Mansions, one of China's four classical novels. On the basis of hard experiments, Edison finally invented the electric light bulb with his own intelligence, and later became a world-famous invention king; When the great writer Hawking was seriously ill, the doctor told him that it was only a few months, but he still didn't give up writing. Many things happen. In just a few months, Hawking wrote works such as Black Hole.

At the thought of this, a warm current suddenly flooded my whole body. Compared with them, my little difficulties in study are really insignificant.

So, I re-examined my thinking of solving problems, deliberated repeatedly, drew line drawings, reviewed the examples explained by the teacher in class, and finally overcame the difficulties.

This incident also made me further realize that some things can't be really understood without personal experience.

Unit 1 of Grade One, Unit 1 of Composition: This is my child facing the rising sun, an "urban" woman who pursues fashion and dares to think and do. This is me, a thirteen-year-old girl.

When I was a child, I was naive, lively and strong-willed. I am the apple of my family's eye and a veritable "Miss Jiao".

Now I have changed, become more competitive, and have stronger self-esteem and vanity.

Although I still have that unique personality, the laughter in the past has become quiet.

But be careful, it's not that you will stop laughing, but that you will become a "lady".

When I was a child, I was alive and kicking, and I was busy worrying my parents and carefree. I am addicted to eating, drinking and having fun all day. I can't forget that my father and I fought for a channel, and I blushed. If it hadn't been for my mother's clearance, the "Iran-Iraq" war would have started again. I can't forget playing games in front of the computer, being criticized by my mother for "forgetting to eat and sleep" and playing with my former friends.

Now, I have made a 180 degree turn, reliving the warmth of the past in the busy street where people come and go. Everything makes people want to stay, stick it on a notebook and turn over a new page, and there I am in a sparsely populated, eye-catching bookstore and attractive video store ... I am eager to swim in the sea of books, learn the essence and listen to the wonderful.

At this time, release all the charm and devote yourself to your hobbies.

This is me, a dazzling bouquet of tulips and a pot of Milan.

The pace of growth often cannot keep up with the good time. In a blink of an eye, my colorful childhood passed, and the arrival of 13 years old was like all the sudden "bad luck", which also awakened my sleeping heart. I am no longer an ignorant and mischievous person, and my parents are beginning to be wary. They have started to save money and pay close attention to their children's manners and behaviors. There are many commandments. What can't you give? No romance novels, and so on. Even extracurricular books are read by parents. I'm afraid that unhealthy content will defile your mind, but I still do whatever I want. Now I have lofty ideals. I will take this as a starting point, then go up, be admitted to key high schools and famous universities, and be an excellent host after graduation. Although far away and unfathomable, there are a series of fantasies.

Yesterday's me, today's me and tomorrow's me constitute a vivid and innocent self-portrait.

The morning sun is waving to me, and the grass is nodding. Let's work hard.

The composition of the first unit of Chinese in the first day of the People's Education Edition is all the sea, and I am a grain of sand.

I, hidden in the vast sea of people.

I have neither a soft figure nor bright eyes, but I have an enterprising heart, a watery dream and lofty ideals. I firmly believe that I am full of poems and books.

I don't want to go with the flow.

In The Road Not Taken, Frost once wrote: "There are two roads in the yellow forest, but unfortunately I can't set foot in them at the same time.

""and I chose a less traveled road, which decided my life path from now on.

"Only in front of the public can I become a real ordinary person.

I don't want to follow the vulgar old road of others and live the same vulgar life as others.

While stealing from others, you also deny yourself.

I don't want to go with the flow.

In The Road Not Taken, Frost once wrote: "There are two roads in the yellow forest, but unfortunately I can't set foot in them at the same time.

""and I chose a less traveled road, which decided my life path from now on.

"Only in front of the public can I become a real ordinary person.

I don't want to follow the vulgar old road of others and live the same vulgar life as others.

While stealing from others, you also deny yourself.

Me, humorous and tolerant.

I never like to see others pull a long face. I think other people's smiles are the most beautiful scenery in the world.

So every day I will become a pistachio and bring them joy as much as possible.

"The ocean is wider than the earth, the sky is wider than the ocean, and the human mind is wider than the sky.

"Tolerance makes the narrow mind embrace all the rivers, so I regard other people's faults as jokes.

I want to be myself.

Mr. Qi Baishi once said; "Learn my life, such as my death.

"Can't walk out of the framework of predecessors, nature also won't have their own world.

When bubble novels became popular, I felt I was wasting my time. When online games are popular, I feel that I am wasting my youth.

Be yourself, see the real me clearly, show 12 confidence and tell yourself: "I am who I am, why should I be like him?" ! "Throw away those artificial flashy carvings, show your trump card, pursue your own personality, be yourself, be the best yourself! Me, aggressive.

I am a small grain of sand, but I am not willing to lag behind and have nothing to do all my life.

I would like to be the master of life and an immortal tear.

There is a long way to go in Xiu Yuan, and I will go up and down.

I am eager to go to the tower of art, the top of culture, the house of career, and celebrate the edge of success. I will live up to this era of blooming flowers, leave a solid and steady footprint, and spread beauty and love to the world ... This is me. I am in the prime of my life and full of energy.

This is me, humorous and tolerant, unwilling to lag behind.

I am 1.63 meters tall, with a tall ponytail, a pair of bright eyes, a small round face and a sweet smile. This is me, a junior one student. I have a wide range of hobbies. I like reading, listening to music and reading English ... Zhang Haidi's experience taught me how to face misfortune calmly, and then I feel that my life is full of hope. I am happy and straightforward. I am full of confidence in myself. How many times have I participated in various elections with 1000% confidence, but I was defeated by 200% in the end. Facing the cruel reality, I feel disappointed and sad because my efforts have not been rewarded. However, I didn't collapse. Confidently let failure hone my will. Self-confidence is the first secret of success. I firmly believe that as long as I make unremitting efforts, there will be applause that really belongs to me one day. My persistent goal is to be admitted to Beijing Foreign Studies University, to become a diplomat in the future and to contribute my meager strength to the motherland. This is me, a little girl who likes reading, is full of confidence and has a goal. Because I didn't know it was the first volume.

Write down my beautiful sentence, what is youth? Youth is hope.

What does youth need? Youth needs to be grasped most.

Youth is like a poem, a dream and a fire.

Young life pursues a romance and seeks a trace of tranquility, which is poetic youth; A pure heart yearns for a bright future, designing one magnificent blueprint after another, which is dreamlike youth; Full of energy, we use that persistence and * * * no regrets to find the value of life. This is passionate youth.

Youth will go, but grasping youth in youth, cherishing her and loving her will not make you sad. At least when she leaves, I can say, "At least I cherish it!" "The heart of youth is so ups and downs that he needs a helmsman to sail this uncertain boat into the light.

Grasp the direction, don't be confused; Grasp yourself; Never be sad.

The footsteps of youth flow, and the road of life depends on yourself to explore.

Don't sigh, don't stop, think, struggle, and don't let the years pass.

The wind chimes of youth knock on my heart, the colored flutes of youth blow my dreams, and the notes of youth drive me to hope.

This beautiful youth season is the time for us to sow hope, cherish it, love it and seize it to make it shine in our hands.

Youth is not for waste, but for struggle.

Youth is full of vigor, we are full of vitality, and we dare to do it! Youth, we must do our best to do what we should do and reach a height that we can't even think about! Youth is not short-lived. As long as you have a young heart, as long as the words struggle and dedication are written in your life, you will have a bright youth like the sun.

What is the composition of the final exam of the first grade Chinese in People's Education Press? Hello, landlord, I'm glad to answer your question. 80% of this exam is a narrative composition.

So it must be very simple for us. If we guess, we can't guess. How much time is left in the exam? Read your composition more when you have time. The content of the composition does not need to be memorized. You have to look at the writing method. I often write a composition first, then the words, then the beginning (scenery description) and the end (topic description). This is very important, so you are sure to get high marks. The teacher said that because he also went home to give a reporter something, he just gave it to you depending on how your handwriting was and whether your beginning was beautiful or not.

What composition should I write in Unit 2 of the Junior One Education Edition? 1 Unit 2 Composition: Write about a person's mother's hands. There are industrious hands, lazy hands, rich hands and dexterous hands in the world. However, I wrote about her industrious hands.

Her hands are not that big. Long-term labor has made the cocoon skin climb on her fingers, and a layer of light black skin has grown on the back of her hand.

When the cock crows three times, mother's hands have already started to work: busy making breakfast.

Near noon, her hands began to work again: busy cooking lunch.

In the afternoon, her hands began to work again: busy cooking dinner.

At night, when the moon is high, my mother's hands are working again: busy washing clothes.

In short, my mother's hands have been working.

Mother's hands are hardworking and full of maternal love.

I remember a cold winter afternoon.

I am doing my homework and my mother is doing needlework.

It was late at night, and the weather became colder. My hands are shaking, I dare not write, for fear that I can't do my homework well.

At this time, my mother came up to me and said with concern, "Is it cold?" I gently clamped my hand in hers.

Suddenly, I felt extremely warm.

With her encouragement, I finally finished my homework seriously.

I remember another morning in the middle of winter, and it was very cold.

In order to keep out the cold, my friends and I went skating by the river.

I accidentally fell into the lime pit.

I tried to lift my feet, but my boots were stuffed with lime.

"I can't wear it." I resolutely took off my boots and prepared to let my mother wash them for me. Another thought: My mother will criticize me.

Finally, I came up with a way to kill two birds with one stone. I hid my boots under the door until it was warm.

The next day, the weather was a little warmer, so I went to wash my boots.

But there are no traces of boots under the door.

I was so anxious that I almost cried. After a while, I calmed down and went to look elsewhere.

No sooner had I found the back door than I heard the familiar sound of "wooshing, wooshing, wooshing".

Isn't that the sound of mom's hands working? I followed the sound. In the yard, I found my mother who was washing my boots.

Her hand was red with cold and cracked several times.

Although it was very cold, there were still a few glittering and translucent beads of sweat slipping from my mother's cheek. I walked up to her, grabbed the brush for brushing my boots and said, "Mom, I'll wash it.

"Mom said with concern," Zhen Zhen, I'll wash it.

"I didn't promise, but she has taken her boots and brushes.

Finally, mother washed it.

After washing, she carefully dried her boots. Tears blurred my eyes when I put them back on.

Ah! I want to praise, praise mother's hand, but also praise you-mother.

Syllogism: phoenix head, pork belly, leopard tail.

Start and end with some famous sayings, comparisons, metaphors and personification.

Write casually in the middle.

When you know each other, you can't do anything in an instant. You can't get to know each other at all. Let's just say you have a good relationship.

Instantaneous memory can only remember those special abnormal things, so you just need to write down its special features.

My most unforgettable teacher grew up with many teachers who taught me.

Some of these teachers are gentle and some are rude; Yes, but there are also; Some are always responsible for students, while others are never responsible for students.

My most unforgettable teacher is my sixth grade head teacher, Miss Lin.

Miss Lin is tall and thin, wearing a pair of glasses, and always has an amiable smile on her mouth.

Her smile seems magical. As long as we walk into the classroom and see her rising corners of the mouth, we can immediately enter the tense state of learning.

I remember when the sixth grade started last semester, I didn't know why I couldn't keep up with my study progress, and my homework error rate soared. Every time the teacher checks my homework, I complain.

After a while, the teacher found my situation and began to notice me.

One morning, as soon as I escaped from a bad Chinese class, the teacher stopped me: "Lin Runke, bring it to the office!" " "I thought: this is bad! My terrible homework came into view.

The autumn wind is blowing slowly, which should have taken away the heat in late summer, but now it has brought a lot of pressure, which makes me feel.

We walked slowly into the teacher's office.

Unexpectedly, the teacher changed the seriousness in class and gently said to me, "Lin Runke, your homework has made many mistakes these days." Is there anything you can't understand? " The teacher's voice flows like a clear spring on the mountain, clear and soft, and it sounds comfortable and cordial.

The pressure in my heart disappeared and I couldn't help relaxing.

Seeing that I was no longer nervous, the teacher smiled and pointed at me and said, "You didn't fully understand these topics. Let me tell you more.

"Then the teacher began to explain in detail.

The teacher spoke for half an hour this time.

This lecture helped me a lot and gave me a good feeling.

After another half hour, I have corrected all the questions by myself.

When the teacher saw that I had mastered all the problems, he smiled with relief.

This smile is like a spring breeze, which warms people's hearts and makes me unforgettable for a long time.

On the way of growing up, I taught a lot, which I can't forget in various ways.

Among them, the most unforgettable thing for me is this teacher Lin, whose smile will remain in my memory forever.
