The child broke the vase.

1. There are four children, only one has broken the vase, and only one is telling the truth. Lei Lei is telling the truth, and it's Jun Jun's fault.

Idea: This kind of reasoning is a rebuttal, and the hypothesis method can be used. If Mao Mao is telling the truth and Fangfang broke it, then it is also true that Jun Jun said he didn't break it, which is not true. Similarly, assuming that Fangfang is telling the truth is not true, because it will also become that Jun Jun is telling the truth. Now, assuming that Jun Jun is telling the truth, the remaining three people are all lies. If Lei Lei says Fangfang is lying, it will become that Fangfang is not lying. Jun Jun Fangfang's truth is inconsistent with the meaning of the question, so the exclusion method knows that Lei Lei is telling the truth. Of course, we continue to reason, Lei Lei is telling the truth, the other three are lies, and Jun Jun is also a lie, so Jun Jun broke it.

2. Look at the picture and write down the words about the broken vase. On Sunday morning, my father went to the factory to work overtime, and Komatsu did his homework at home alone. Suddenly, the phone at home rang, and Komatsu hurried to answer it. He accidentally knocked over the vase next to the phone and broke it. Komatsu was too scared to know what to do. He doesn't even know how to answer the phone.

After a while, the voice of "Ding Dong, Ding Dong" came from outside, and Komatsu knew it was time for his father to get off work. He walked softly to open the door for his father. As soon as I opened the door, my father saw the broken glass on the ground. He frowned and asked Komatsu, "What's the matter?" Komatsu lowered his head and whispered, "I accidentally broke the vase." Please forgive me. " Dad said, "well, go get the broom and clean up these pieces." Komatsu's father didn't mean to blame himself. He picked up the broom like a gust of wind and quickly cleaned up the debris on the ground.

A few days later, Komatsu made a delicate vase with Sprite bottle in the school handicraft class, inserted some paper flowers made by himself and put them in the original place. Dad called it "environmental protection vase" and "honesty vase".

3. One thing in the growth of the fourth grade composition is not less than 350 words. There are many things in life, including joys and sorrows, laughter and tears. Life is really colorful. Of course, I am no exception. In my life, there is one thing that I remember vividly.

I remember it was a scorching summer day, and the weather was so hot that even the clouds gave off strange light. I looked after the house at home that day. The room is stuffy, and my mood changes with the weather. I thought to myself, "It's too hot today. If I tidy up the room, not only will the room look brand-new, but my mood will also be suddenly enlightened. " After thinking about it, I ordered a basin of water and began to tidy up the house. When I was in a good mood, I accidentally bumped into my mother's favorite thing, the vase, and it fell to pieces. The broken sound of this vase came into my mind like a bolt from the blue, which made me look flustered and at a loss. I thought, "If my mother knew I broke something she loved, would she say me?" Scold me? Flat ... "I dare not think about it any more. Just when I was in a hurry, I was caught off guard and my mother came in from the outside. When she saw the vase broken, her knife-shaped eyebrows stood upright and she was shocked: "Who broke it?" "At that time, I wanted to tell my mother about it from beginning to end, but I didn't dare. Really answered that sentence-the heart is willing but unable to do so. I squeaked and said, "It was broken by my 5-year-old brother next door. "My mother is a child who is not sensible, and she will never pursue it again. But I could see from my mother's eyes that she was very unhappy, so I avoided her everywhere, and of course my interest in cleaning the house was forgotten.

At night, the storm had subsided and I came to the yard listlessly. I feel as if the moon is not as bright as usual, the breeze is not as gentle as usual, and the flowers and plants are not as lovely as usual. They all seem to accuse me of unrepentant behavior, and I feel ashamed. I went into the house in frustration, thought for a long time, and finally decided to confess it to my mother. I walked to my mother with my head down and admitted my mistake in a low voice. I thought my mother would scold me, but what I never expected was that my mother said a word to me very kindly: "Son, as long as you can boldly admit your mistake, it is more precious than thousands of vases ..."

My mother's words were deeply imprinted in my heart and benefited me for life.

There are three stories about the broken vase.

After the vase was broken, a ten-year-old boy accidentally broke his own vase. His mother came over and beat him up.

When a boy grows up, he is timid in everything and has no great promise. My mother sighed in her later years: Why are all the children raised by others promising? A ten-year-old boy accidentally broke his vase.

His mother came over and said with a smile, "As long as my son is happy, what is it to break a small vase?" "Later, the boy got into the habit of throwing things, especially bowls with gold edges. When he grew up, he completely lost all his wealth.

He is the son of Shen Wancai in folklore. A ten-year-old boy accidentally broke his vase.

His mother came up to the boy and said, "Can't you get some inspiration from the broken vase?" ? Our vase can't be broken in vain! "The boy thought about the vase for a long time, but he couldn't think of anything, so he had to pick up the pieces one by one. Later, whenever he broke something, he had to think and pick it up.

Finally, one day, the boy found that all broken fragments have their own rules, that is, the weight ratio of large fragments to second-largest fragments is 16: 1, the weight ratio of second-largest fragments to middle fragments is 16: 1, and the weight ratio of middle fragments to smaller fragments is the same. Later, the little boy applied his findings to astronomy and archaeology, and successfully restored the remains of cultural relics and meteorites to their original appearance.

The boy is Jacob Bohr, a famous great scientist.
