Looking at home and abroad, looking at ancient and modern times, countless facts prove that doubt is not only the cornerstone of success, but also a stumbling block to progress. Therefore, it is necessary to "doubt its material" in order to benefit.

Doubt is the beginning of thinking and the end of learning. Newton should thank the apple that hit him on the head. Even if he can't be the golden apple pursued by Venus, he should be grateful for the doubts that arise from it, which create "gravity". If Copernicus learned and undoubtedly believed in authoritative saints, where would Heliocentrism come from? Doubt is accidental, but it is inevitable. In the accident of doubt, there are bound to be new discoveries. Only those who have the spirit of questioning and exploring have "doubt" about "no doubt" and make efforts to explore, can they find something, create something and invent something. Scientific research is to break the "doubt". Only by breaking the "doubt" can we create things and invent things. There is no doubt about the development of society, then it is breaking, then it is innovation and reform, and finally it is progress.

Doubt produces knowledge, doubt creates talents, and promotes social development and the progress of the times.

To be truly successful, bold questioning is the first step. Liu Xiang often asks himself: Can China people really fail in the world track and field? No, he started from doubt, worked hard, broke the myth of track and field in Europe and America with practical actions and perfect performance, and achieved remarkable success. Ceng Zi said: Think about yourself three times a day and be unfaithful to others. Don't believe in making friends? Can you pass it on? The ancients were able to reflect on themselves three times a day and doubted themselves, not to mention us modern people?

Doubt once gave birth to hope and success, but it may become a stumbling block and a roadblock on the way forward. Sometimes paranoia is the enemy of life. If the prince of Zhao doesn't listen to the intrigue of Qin and doesn't doubt that Lian Po and Li Mu will unify the six countries, it will take at least some time. Perhaps, there would be no ups and downs of "Jing Ke stabbing the king of Qin" and "Chu-Han hegemony". Countless heroes bend over to doubt, countless talents bend over to doubt. Since then, paranoia has become a crime and a magic.

Suffering from failure is often the first step to be suspected. If a person doesn't trust his subordinates, relatives and friends, classmates and people around him, he will die alone or even depressed. Some people doubt their abilities and miss many opportunities. It's a pity that the horse has no front hoof, so doubt yourself!

In short, there is nothing wrong with doubt, but it is too useful and useful for those who use it. "Suspicion" is two stones with the same texture, one is weathered stone, the other is bright jade, but it is chosen by different people with different results. Only by applying "doubt" to materials can we get the cornerstone, not the stumbling block.

Only because of the "doubt" of materials, rivers and seas become deep without choosing trickle, Mount Tai is big because of soil, and the wise master is not far from the flourishing age of talented people. Why not question the materials? Let doubt benefit mankind!

China people, what is it? It is a clear spring in my heart.

The first ray of sunshine in the morning is not in the treetops, let alone where the sea meets the sky, but at the moment when you open the Chinese book. Every day, regardless of study, work and life, we get together with our friend "China people" to nourish our body and mind and sublimate our souls.

When you read Chinese, you read heroes from generation to generation: Zhuge Liang, with extraordinary wisdom and courage; A generation of tianjiao Genghis Khan; Wu Zetian, the first female emperor; Tang Bohu, a romantic genius; Yue Fei loyal to the country; Fan Zhongyan, who is "worried about the world first, and happy after the world"; Huang Jiguang who blocked the enemy's muzzle with his chest; Qiu struggled in the burning fire without saying a word ... China people, a clear spring in my heart!

Open the language and open the scene of the war years. Language allows us to return to the palace of history and witness that painful and eventful time. Listen with your ears blocked and look with your eyes open: the gunshots are still ringing, like huge thunder; Enemy planes glided rapidly in the sky; Bullets fell from the sky in droves; There are fires everywhere, corpses everywhere, and the battlefield is immersed in the sound of sadness ... Nevertheless, our revolutionary martyrs have laid so many beautiful mountains and rivers. Turning over the language, turning over a page of hard struggle, let us know that happiness is not easy at all, and let us know how to cherish today's wonderful time. Language is a clear spring in our hearts!

You can't have your cake and eat it, and you have to give up your life for justice.

China people, a clear spring in my heart!

When I met a frog, I asked, "Brother Frog, how can I get to the river?" The frog pointed to the front and said, "Go straight ahead and you will reach the river in a moment." The crab walked for a long time, but it still didn't reach the river. Later, the crab met the frog and accused me of saying, "You made me suffer. After walking for a long time, I still can't see the shadow of the river."

In fact, many times, changing the perspective of things is to change the attitude of doing things. For example, in the face of a thing, do you see the dark side or the bright side?

(60 points) 65438+ 10 On the evening of May 5, Sun, the driver of Shanghai Volkswagen Taxi Company, received a guest who was going to Puxi for dinner. As soon as the car entered the tunnel, the guest suddenly asked to turn around.

Sun said, "You can't turn around in the tunnel, only when you get to Puxi." The guest said, "I went out to change my pants and didn't bring any money."

If you turn around in Puxi, you won't have time to eat. "It doesn't matter to Sun Dao with a smile, I can send you there for free. "

When the bus arrived at the hotel, Sun handed in three boarding passes of Volkswagen and said, "You have no money with you. If you go back later, you can call the above number and ask the Volkswagen taxi to pick you up. These three tickets can pay the fare in 30 yuan. Even if it is not enough, the Volkswagen driver will send you back. "

Two days later, new york Bank Shanghai Branch hired him as the president's driver. It turns out that this guest is the president of new york Shanghai Bank Branch.

In the future, Sun said to the reporter who interviewed him: "It's nothing to send guests for free. I just play cards according to the routine." Sun followed the rules and got a good job.

In life, some people break away from convention and seek opportunities for development. Different people have different understandings and practices of conventions in different environments.

Please use "often".

5. Write a short essay with the theme of picking up money. There are good and evil, beautiful and ugly in the world. What do I admire most? Of course, I admire change the most! What do you mean you can't hide money? As the name implies, "picking up" means picking up, "gold" means something similar to money and valuables, and "not knowing" means not taking it for yourself. If you don't pick up the money, you won't keep anything valuable for yourself. Not long ago, I experienced such a thing.

One Saturday morning, I walked home slowly from the outside. Suddenly, a stranger called me from a distance and heard that it was an uncle. Perhaps because teachers and parents told me too much, I couldn't help thinking that this person might be a bad person who abducted children. All kinds of ominous premonitions flashed in my mind, and my legs could not help speeding up. My uncle thought I didn't hear, so he stepped up. After a while, he caught up with me. So, my heart beat faster, and I said to myself, "It's over, it's over, and now it's completely over." At this time, my uncle said to me out of breath, "Little friend, have you lost money?" I felt in my pocket, and sure enough, the 20 yuan my mother gave me was gone. My uncle handed me the money and left. Looking at my uncle's wronged back, I was too ashamed to say "thank you"!

Whenever I recall this incident, that scene will come to my mind, not only because I got the lost money, but more importantly, I realized the valuable spirit of my uncle in finding it. Yes, can others be like that uncle when they encounter similar situations? Everyone has wealth. Although I got the money from 20 yuan, what I admire more is my uncle's noble behavior of helping others and having no money to change.

6. Write an essay outline with the theme of "there is no doubt about mountains and rivers, and there is no ignorance about a village", and write an essay outline with the theme of "there is no doubt about mountains and rivers, and there is no ignorance about a village":

Title: Every good thing has its day.

The beginning: the confusion of writing "mountains and heavy waters have no way to answer doubts"

Middle: you can write one thing, which is divided into three points. First, how to step into confusion; Second, how to get rid of or overcome it; Third, happiness after getting rid of or overcoming.

End: Deduct the topic or the corresponding beginning, write the happy feeling of "another bright future village" and express your inner feelings.

Note: to use rhetoric more, you can insert some famous sayings and epigrams, literary poems.

Example: There is always a time when a bright future comes out.

Wandering at the crossroads, indecisive, not knowing how to choose the road to success. At that time, I seemed to have lost myself and lost my way forward.

I remember it was physical education class that day, and the teacher asked us to practice two and a half layups. At that time, I was full of confidence and thought my cricket board was good. I didn't notice this so-called two-and-a-half-step layup. The teacher first asked us to run around the playground twice, and then did some preparatory activities and began to lay up. The teacher divided the students into two groups, male and female, and then the training was carried out in an orderly way.

I thought at that time, what's so hard about it? I'm sure I can make it once. It will be my turn soon. I picked up the basketball and began to throw the ball. I failed the first time. I thought: this must be a mistake. I am smugly making excuses for my failure. The second layup failed, and I suddenly felt that God had played a modest joke on me, which made me 1.7 meters tall, but even the basic movements such as layups were difficult to complete. Suddenly, I was very sad, so I left the basketball court in a gloomy mood and sat there watching my classmates lay up one by one. I feel very failed and lonely.

At this moment, my good friend Xiao Ya came over, looked at my sad face and asked me why. I just told him everything. He was very angry and said to me, "Are you knocked down by this sesame-sized setback?" If even this small hurdle? ? If you can't cross it, then you are a complete coward. "Yes, just imagine where there would be bright electric lights today without Edison's unremitting efforts; Without the perseverance of the Wright brothers, there would be no plane soaring in the sky today; Without the unexpected discovery of the alchemist in the Tang Dynasty, there would be no gunpowder today. Otherwise ... it is their optimism that "there is no doubt about mountains and rivers, and there is another village" that will become a bright star in the history of development! I am so weak and stupid. So I regained my confidence and stood on the basketball court again. I must succeed this time. ...

Only after experiencing wind and rain can there be a more beautiful rainbow; The mountains are heavy and the waters are complex.

7. Write a 600-word composition (imaginary composition) on the topic of "Moon".

With the continuous development of science and technology, people's interest in the moon cannot be higher. Now the moon is exactly the same as the earth. Let me introduce you first.

There are many clouds on the moon in the future, and there are all kinds of buildings on these clouds. Maybe you will ask, how can you go up and live like this? You don't have to worry about that. There is a beam of light on the cloud. As long as you go to the light, that light will take you there to live, so you don't have to worry about how to live there. Do you have any questions? If not, I'll go on!

There will be some necessary things in life in the future, such as banks and amusement parks, but they are all underground. There is an elevator underground, and there is a "commander" under the elevator. As long as you tell the commander where you want to go, the elevator will take you where you want to go. Besides, if you are a thief, you will be fooled by me, because the elevator has an automatic discriminator. As long as you want to steal, the elevator will transfer you to Venus through "time-space transformation", and when you don't want to steal, the elevator will transfer you back. There will be "tricolor trees" on the moon in the future. They are yellow trees, green trees and mangrove trees. Green trees are trees on the earth. Yellow trees can shine effectively and catch all those who steal fruit. Mangroves can bear more than 10 thousand fruits a second, so people don't have to worry about not selling them. With the "tricolor tree", the moon will make people live better.

It is convenient for people to walk on the moon. Because the shoes everyone wears are specially made, these shoes can generate gravity and let you walk directly. Save jumping around every day.

If you are thirsty, no problem! We have a rain every three hours, and all we get is drinking water. You can increase your water quantity. This can not only quench thirst, but also make plants drink enough water and grow healthily.

The safety performance of the moon in the future is also very good. Because we have prepared an alien harmful substance recycling machine for you, it can stop the danger when the asteroid runs to the moon and turn it into several daily necessities, which is also very helpful to human life. I believe that with the development of science and technology, this "second home" will definitely appear. Therefore, we should learn knowledge well from an early age and make our motherland's technology better and better in the future!

8. Flying down to thousands of feet, it is suspected that the Milky Way has set for nine days, and the incense burner in Rizhao gives birth to purple smoke.

Looking at the waterfall hanging in front of Sichuan.

Flying down from 3,000 feet,

It's been nine days since I suspected that the Milky Way had set.

This is a landscape poem written by the poet Li Bai when he lived in seclusion in Lushan Mountain at the age of about fifty. This poem vividly depicts the magnificent scenery of Lushan Waterfall and reflects the poet's infinite love for the great rivers and mountains of the motherland.

Interpretation of poetry

Ziyun smoke, the incense burner peak under the sun, fills the air, and the waterfall looks like a long white practice from a distance, hanging high between mountains and rivers. The agitated water column tumbled down thousands of feet from the cliff, in a trance like a galaxy falling from the clouds.

words explanation

Incense burner: censer peak is a peak in the northwest of Lushan Mountain.

Purple smoke: Under the sunlight, the clouds are purple.

Appreciation of poetry and prose

Three thousand flies, nine days in a row. With such boldness of vision and infinite imagination, I'm afraid Li Bai is the only one in ancient and modern times.

In this poem, three words are skillfully used: a word "Sheng" not only brings the incense burner peak to life, but also shows the scene of mountains and clouds rising; a word "Hanging" depicts the image of a waterfall pouring in Yuanwang; A word "falling" points out the majestic momentum of the waterfall. Through the integration of these three words, it seems that Lushan Waterfall is just around the corner. "Inside, the hair is outside. I want to fall from the sky, with both form and spirit. This is the ancient people's evaluation of this poem, which can be described as the best among many poems about waterfalls.
