Thales (about 624 BC-about 547 BC), a famous scientist, philosopher and politician in ancient Greece, was born in an aristocratic family that ruled Miletus, with high political status and rich family.
In order to seek knowledge, he traveled and studied in Egypt in the east, and continued to learn scientific knowledge after returning. In this way, he inherited little money.
One night, Thales walked on his back to a square. He is observing the stars in the sky wholeheartedly. He didn't notice that there was a pit ahead. When he slipped, his whole body sank in.
A businessman came up and sneered, "You claim to know things in the sky, but you don't know things under your feet. You have benefited a lot from learning knowledge. Falling into the pit is the benefit of your knowledge! "
Thales climbed out of the pit and calmly replied, "Only those who stand tall have the right and freedom to fall into the into the pit from a height. An ignorant person like you can't enjoy this kind of right and freedom. A man without knowledge is like lying in a pit, and he can never climb out. How did he fall into the pit from above? " His witty retort bored the businessman.
However, the businessman didn't want to give up and continued to dig at Thales: "But what can your profound knowledge bring you?" Gold or bread? "
Thales said, "We'll see!" He used a wealth of scientific knowledge such as astronomy and mathematics, and after careful prediction and calculation, he came to the conclusion that next year will be a bumper year for olives. So he sold his property and rented all the olive oil presses nearby at a fairly low rent. The next year, olives really got a bumper harvest, and people competed to rent oil presses. At this time, Thales turned to rent an oil press at a high price.
One day, Thales saw that the businessman who had laughed at him also came to ask for rent, so he came forward and said, "noble rich man, did you see it?" I used my knowledge to get these oil presses. Rich people like you can only turn to me for help. However, what I am after is not money, but to prove that scientific knowledge is of great use to people's lives. Knowledge is priceless and the greatest strength! "
An essay entitled "priceless knowledge", more than 600 words. It's best not to copy. I walked leisurely in the street. Suddenly, a scene of deja vu attracted me deeply: "Let's play together!" " A little girl warmly invited a little boy. "I don't want it, you go away!" The little boy rudely refused this warm invitation.
I can't help but stop. The scene that happened at the age of seven is still as clear as yesterday: "Let's play together!" " "I naively invited a little boy with a sad face and a ponytail." I don't want it, you go away! "The little boy sad face, rudely refused me.
In the big yard of the kindergarten, I am playing the game of "the eagle catches the chicken" with a group of children of similar age. We had a very dark time and got carried away. However, I always feel that something is out of tune with our excitement. So, taking advantage of the gap caught by the "eagle", I looked at it by feeling. I saw a little boy sitting alone in the corner, looking at us with envy. When he found me looking at him unscrupulously, he immediately withdrew his eyes, turned his face and looked away with a nonchalant expression.
His eyes convinced me that this was a lonely little boy. I can't concentrate on the next game. This little boy is like a magnet, which firmly attracts my attention. "Oh dear!" Absent-minded, I tripped over a child while avoiding the pursuit of the eagle. I was wearing a skirt and lying on the concrete floor, blood oozing from my knees.
I can only sit alone and watch them get excited. I turned my head and looked at the little boy who was in the same boat. He still stared at the children immersed in the game with envious eyes. I slowly, bit by bit moved to his side, gently pushed him, smiled and invited: "Let's play together?" I saw a trace of joy in his eyes, but it disappeared from his eyes before I caught it. "I don't want it, you go away!" He straightened up and looked gloomy. He spoke as if he was injured, and then walked away like a plague.
All the other children came to tell me not to play with him. His parents divorced and no one wanted him.
At that moment, I suddenly felt heartache and longed to be friends with him. The second time, the third time and the fourth time, he turned me down. Until the fifth time, I sent him a warm invitation. He hesitated, and I took the initiative to reach out and led him to the playground ... that day, his face was full of sunshine, and I saw the two lively and lovely little tiger teeth in his mouth!
Until now, we are still growing friends hand in hand.
Once, in a place where he seldom played, he told me that he was very grateful to me. I extended my hand of friendship to him, pulled him out of the lonely and dark corner, let him bathe in the sunshine and warm his heart.
After listening to this sentence, I feel happy: a simple hand can also get a friendship.
Full score decryption:
In fluent language, the article tells us a faint friendship story as fragrant as gardenia: a passionate little girl pulled a melancholy little boy out of a lonely corner with her own persistence, and their friendship was faint but long.

There is never a perfect life.
When you feel sorry for yourself and blame others in the face of adversity, have you ever thought that somewhere in the sky, there are a pair of wise eyes watching you silently?
Those are God's eyes.
God holds a magnifying glass in his left hand and a calculator in his right hand, constantly observing every move of the world and counting what everyone has paid, including sweat, strength, love and even blood and life. At some point in the future, God will return all that his children have done for them. I have never paid much because I particularly like someone, and I have never paid less because I don't like someone. In the eyes of God, everyone is equally lovely and naive. However, when God finds that someone is no longer clinging to his own ideals and looking forward to the future, God has to give up this person with regret.
Some people say, "It's God's humor, cruel humor."
God said, "Being strong and heartless is the sorrow of human beings and the sorrow of ignorance."
what do you think?
Are you willing to be abandoned by God?
When the glass of reality mercilessly scratches your tired face, do you still walk firmly against the cold wind?
When the pressure of reality shatters your remaining self-confidence, do you still cling to the seeds of your ideal and refuse to let go?
Friend, when you find it difficult to walk, please stop and pour the sand out of your shoes. Don't let the sand in your life hinder your progress.
My friend, when you shed tears of regret, please stop and wipe the tears from your cheeks. Don't let tears blur your signpost.
Don't believe that there is only wind, frost, rain and snow in life, and there is no clear sky in Wan Li.
You don't believe that others can sail the ideal boat to the other side of success, but your sculls will be ruthlessly shattered by the storm.
Don't hesitate, don't wander, stick to the road you think you should take, and remember that the most difficult time is the closest to success. Even if you are knocked down 100 times, you still need the courage to stand up and face 10 1 times. This is the persistence that a person should have, and it is the persistence of life.
There is never a perfect life.

Filial piety is priceless.
The shopkeeper stood behind the counter and looked out of the window bored, but he was thinking about the business that had been depressed recently.
A little girl came in, her whole face pressed against the window, looking for it carefully. After a while, she stared at a sapphire necklace with ecstasy.
"I want to buy it for my mother. Can you pack it beautifully? " She said.
The shopkeeper looked at the little girl suspiciously with clear eyes and asked, "How much money do you have?"
The little girl immediately took out a small bag from her pocket, opened it carefully, then spread the money in her palm and said excitedly, "Are these all right?" Without waiting for the shopkeeper to answer, she added, "Today is my mother's birthday, and I want to give it to my mother as a gift. I haven't seen my mother smile for a long time. I'm sure my mother will like this necklace. She will definitely smile beautifully, because the color of the necklace is just like her eyes. "
The shopkeeper listened carefully, took out the necklace, put it in a delicate little box, wrapped it in beautiful red wrapping paper and tied a green ribbon on it. Then he said to the little girl, "Take it and be careful." After patting the little girl on the head, she smiled and watched her go home happily.
At the end of the day's work, a young mother came to the shop, dressed simply but charming. She has big blue eyes. She put the opened gift box on the counter and asked, "Did you buy this necklace from here?" how much is it? "
"The price of our goods is a secret between the seller and the customer."
My daughter only has a few coins, but this sapphire necklace is real. She can't afford it. "
The shopkeeper smiled brightly, gently took the gift box from his mother, carefully repackaged it, tied a ribbon and returned it to her.
Mom was startled.
The shopkeeper said, "The price she gave is higher than anyone else, and filial piety is priceless. What's more, she gave everything she accumulated. "
"Thank you." The young mother finished with tears and smiled again. A tear flashed in the corner of her eye, crystal clear, like a sapphire.
Knowledge is priceless. Looking at the code direction, it is estimated that it is like this:
The main problem appears in the example of quadratic function in the next paragraph.
Look at the above paragraph first:
var a = " var sum"；
var b = " sum = x+y；" ;
Var c = "Returns the sum;" ;
Var square = new function ("x", "y", a+b+c);
alert ( square (2，3))；
At this time, it shows 5. No problem, then go on.
b = " sum = x-y；" ;
alert(square (2，3))；
At this time, 5 is still displayed, indicating that the program has referenced the value of b, and var b = "sum = x+y;" ; You don't look for b = "sum = x-y;" You just defined. ; That is, its existence is ignored.
So the program still presses the first var b = "sum = x+y;" ;
It is easy to explain the following situation.
var a = " var sum"；
var b = " sum = x+y；" ;
Var c = "Returns the sum;" ;
Var square = new function ("x", "y", a+b+c);
alert ( square (2，3))；
b = " sum = x-y；" ;
Var square = new function ("x", "y", a+b+c);
alert(square (2，3))；
When you instantiate this function again, it will look for this B.
As for why the bottom is a B and the top is not a B.
I think it may be that the program directly overwritten the original B value when it found another B value.
So, it's a little close to the principle.
The crux of the problem lies in this B.
It's a little messy I hope you can understand.
Such beauty is priceless.
I have many good friends, but my best friend is He Shiwei.
He Shiwei has dark complexion, short hair cut flush, watery eyes, a flat nose, a small mouth, as thin as bean sprouts, and a watermelon skin on his head. I don't think he can do anything.
I remember one exam, I suddenly found that I didn't bring a ruler and sat in a chair angry. At this moment, He Shiwei came over and asked me, "What's the matter? The exam is coming, what are you angry about! " I said, "Look at me, when I can't live without a ruler, this time." He smiled, returned to his seat, took out his newly bought ruler, twisted it hard and it broke. He handed it to me and said, "Hurry up, class will begin soon." Ding Lingling, class is on! I am very excited to have a ruler. After the exam, I walked alone on the road, smiling knowingly.
This is my good friend * * * (writing about his friends). When he was in trouble, he extended a hand of friendship. Friendship is priceless, and so is this American style. I am proud of having such a good friend.
