The hot Xia Feng blew into the window, and the sunshine outside the window was giving a speech. With the irritability of summer noon, I leaned my head against the window and closed my eyes slightly.

The bus hobbled along like a heavy worm. The car stopped at a stop sign. I opened my eyes and moved my body. A figure came along and I opened my eyes wide. It turned out to be a white-haired and faltering old man. At this time, the workshop was crowded with people, and he moved slowly in the crowd. Are you willing to give up your seat? I muttered in my mind. However, there are still miles from the destination! Don't let it! That's immoral. I don't forget the teachings of my elders at all. Jane. No? In this argument, my conscience overcame my selfishness.

So, I turned to look for the figure of the grandfather. I saw him. He was looking at me. I immediately stood up and stood aside. The old man came over, as if with my heart. He grabbed the handle of the chair and put it down slowly. After he made up his mind, he turned around and gave me a grateful look. I seem to see the corners of his mouth rise and hear him say "thank you". That look, that smile, how kind and beautiful. I looked out of the window and felt sleepy. Instead, it is the joy of the soul. The old man's eyes are like a clear spring, which makes me feel a little cool in the hot summer. I see the scene from time to time, as if I were enjoying a famous painting. However, there are some discordant colors in this painting.

If only I hadn't stood up gloomily. After seven years of school education, these basic ethics of being a man have been branded in my mind. However, why are you so hesitant when taking action? The traditional virtue of respecting the old and loving the young continues to this day. As a descendant of the Chinese people, I should put it in place. If this happens again, I will definitely give in without hesitation.

Now, I really understand what "helping others and being happy" means. While giving, we get happiness and a grateful heart. Compared with this, what we give others is simply insignificant. In the future, I will be happier because I will help more people. I will be a useful boy! Thought of here, my mouth slightly rises, and the sunshine gently holds my face.

Unforgettable things

On my way of growing up, there is one thing I will never forget. After that, I seem to have grown up a lot.

It was last year's New Year's Eve, and students sent cards to each other after class. Red and green greeting cards are given to good friends, who have their own hearts. Everyone was talking and laughing, and their faces were filled with joy. The classroom is full of laughter and excitement.

I was also infected by this happy atmosphere. I took out a stack of written greeting cards and prepared to join this happy crowd. Suddenly, I saw a classmate sitting there alone. Isn't that the famous "naughty king" Liu Kai? Before, he was either running on the playground or talking in the classroom, and he couldn't even control himself in class. Forget the positive energy. But now, he seems to be a different person. What happened to him?

Suddenly, I woke up. It must be because no one sent him a card, and no one said a blessing to him. I can't help feeling sorry for him. Put yourself in his shoes. If I am abandoned by the group and forgotten by my classmates, I will feel a sense of loss.

Thinking of this, I took out the most beautiful greeting card from my schoolbag and thought about it a little. It neatly said, "Liu Kai, I wish you a happy New Year, academic progress and a new level!" Then, I folded the greeting card gently, walked up to him and smiled and said to him, "Happy holidays, Liu Kai!" As I spoke, I took out the greeting card from behind and handed it to him. He looked at me, then at the greeting card and said happily, "Thank you!" " His eyes were filled with new joy. He stood up, raised the card and rushed into the crowd, shouting, "I have a beautiful card too!" " "Looking at him, I also smiled. How important the group is! Everyone can't live without the collective, and everyone needs the warmth of the collective.

Until now, Liu Kai's surprised eyes and sweet smile often appear in my mind.

Mathematical square difference formula calculation problem! Help me, heroes! Solution:

Original formula = 1× (3+2) (3? +2? )(3^4+2^4)(3^8+2^8)

=(3-2)(3+2)(3? +2? )(3^4+2^4)(3^8+2^8)

=(3? -2? )(3? +2? )(3^4+2^4)(3^8+2^8)

=(3^4-2^4)(3^4+2^4)(3^8+2^8)

=(3^8-2^8)(3^8+2^8)

=3^ 16-2^ 16

Detailed process!

Hope to adopt!
