Lotus leaf
Long, long ago, there were no umbrellas in the world. At that time, it was inconvenient for people to go out In summer, the sun makes the skin ache. When it rains, I get wet. Lu Ban was anxious to help people solve this difficulty. He thought to himself, it would be nice to be able to make something that can shelter the sun and rain.
Lu Ban used a lot of brains. Later, he built a pavilion by the roadside with several carpenters. The top of the pavilion was sharp and supported by several pillars on all sides. Then, they built a pavilion every other way and built many pavilions. In this way, it is much more convenient for people to walk. When the rain comes, hide; The sun is uncomfortable, take a break and catch your breath.
Lu Ban did a good deed for everyone, and everyone was very grateful to him. But Luban himself was not satisfied. He thought, what should we do if it doesn't stop raining? People can't always stay in the pavilion.
we have to find another way! Lu Ban thought: If only we could make the pavilion small and let everyone take it with us! But in what way can we make the pavilion light and clever? For this matter, he eats badly and sleeps uneasily.
Lu Ban thought about it for many days, but he still didn't come up with it. One day, it was extremely hot, and he was sweating while working. Suddenly I saw many children playing by the lotus pond. After a while, a child picked a lotus leaf and put it upside down on his head.
Lu Ban thought it was fun, so he asked them, "What are you doing with a lotus leaf on your head?" The child said noisily: "Master Lu, look, the sun is like a big fire wheel. We are not afraid of the sun with lotus leaves on our heads."
Lu Ban grabbed a lotus leaf, looked at it carefully and looked at it again. The lotus leaf was round, with a vein on one side and a cover over his head, which was light and cool.
Lu Ban's heart lit up. He hurried home, found a bamboo, chopped it into many thin strips, and made a shelf according to the appearance of lotus leaves; I found another sheepskin, cut it round and put it on a bamboo shelf. "All right, all right!" He cried with joy, "This thing can not only keep out the rain and the sun, but also be clever."
Lu Ban's wife heard him yelling and ran out of the house and asked him, "What happened?"
Lu Ban handed the newly made thing to his wife and said, "Try this thing, and everyone will take it with them when they go out, so they will not be afraid of the rain and the sun."
Lu Ban's wife looked at it, thought about it, and said, "It's not bad, but it's inconvenient to walk with this thing after the rain stopped and the sun went down. It would be nice if we could put it away. "
"Yes, yes!" Lu Ban was very happy to hear this, so he started with his wife, changed this thing into a movable one, and when he used it, he spread it out, but when he didn't need it, he put it away. What is this thing? It's our umbrella today.
Question 2: Did Lu Ban make an umbrella or Lu Xun made an umbrella? Of course, Lu Ban made an umbrella.
When Lu Ban and his sister were playing in the West Lake, they couldn't enjoy the scenery in the rain. He was inspired by the lotus leaf playing on the child's head in the rain. After repeated experiments, he finally made an umbrella that could be opened and closed. Any invention is inseparable from observation and thinking. We should form the good habit of observing carefully and thinking more when things happen, and be a conscientious person in life. Maybe you will become an inventor. < P > Question 3: What does the story of Lu Xun making umbrellas tell us? We should be good at observing life and think more about Lu Ban's invention of umbrellas. According to the invention of lotus leaf, the story is as follows:

Question 4: Which of Lu Xun's invention stories should be Lu Ban's? Lu Xun is a writer, not an inventor. Lu Ban is an inventor.
Luban's invention of "planing"
Before Luban, carpenters only used axes and knives to level the wood used for construction, and the result was not only good, but also difficult and satisfactory. Later, through a long period of practice, Lu Ban found that the thinner the blade he used, the flatter the surface he made and the easier it was to dry. In this way, this kind of planer gradually evolved from Luban's practice, first with a thin axe blade, then with a blade fixed to a piece of wood and then across the handle, and finally with the blade fixed to the wooden trough-this is the planer we are familiar with today. Lu Ban's wife is also an inventor, who inspired her husband. When Luban planed the wood, she had to stand at one end of the wood and hold the rough thick plate. Because she has other obligations to do, it is not ideal to do such a thing, so she invented a wooden trough for the wood planing workbench to resist the impact pressure of Luban's wood planing, so that the wood planing can be done by one person. The wooden trough invented by her is called the wife of the class.
Mo Dou
Another very important tool invented by Lu Ban is the Mo Dou used by craftsmen (used to set up construction projects). This invention may be inspired by his mother. At that time, his mother was cutting and sewing clothes. Lu Ban watched all this and saw that she used a small powder bag and a thread to print out the desired cut shape first. Lu Ban transferred this practice to a Mo Dou, where he pinched both ends with a thread (soaked with Mo Dou) and put it on the material to be made to print the required lines. At first, Luban and his mother had to hold both ends of the thread. Later, his mother suggested that he make a small hook and tie it at one end of the line, thus freeing her from such chores and making it possible for her to do it alone. In memory of Luban's mother, craftsmen still call this Mo Dou Banmu.
ruler
Another symbol of Lu Ban's invention is that he can correctly draw a right-angled triangle, also known as a ruler, which can tell craftsmen which sizes are irregular and which ones are unlucky according to the rules of divination (geomantic omen). These rulers are still available in Hong Kong today. Saw attaches great importance to the invention of saw, Lu Ban. Or inspired by a blade of grass with a toothed edge cutting its finger, or seeing a cricket cut and eat food with its sharp teeth and leave. Anyway, most of them are described as follows. Luban and the craftsmen were asked to cut down a lot of wood. After cutting for several days in a row, they were exhausted and their axes were dull. At this time, Lu Ban suddenly cut his finger by a blade of grass, and he immediately thought: It must be a good way to make a tool to cut wood like this. He chose a piece of bamboo and cut a row of teeth on its edge with an axe. This new saw cuts the bark easily. When he saws the tree horizontally back and forth, the soft bamboo teeth are quickly polished. However, this proves the principle that saws can break wood. So Lu Ban put down his hand and went to the blacksmith to prepare an iron plate as hard and sharp as an axe, and then made it into a tooth shape. With this first saw blade made by hand, Lu Ban can cut wood accurately and effortlessly by using it on a wooden frame.
bolt
Another invention mark of Lu Ban is bolt. In ancient times, the bolt used by people was made into the shape of a fish and hung on the door. Needham pointed out that Luban replaced these bolts with keys shaped like rammers, which depends on the function of the exact matching parts. Lu Ban's skill can make such a device, and it is said that he also invented the tumbler of the lock, which is still used in many locks today. The symbols of other inventions of Lu Ban are drills, wedges, pulleys, shovels and stone mills for rice milling. The invention of the stone mill was when Lu Ban saw an old woman using a hammer and mortar with great effort. After much consideration, he made two thick stone pieces and cut them into columns, then made holes and hollows on their surfaces, one on top of the other, and put wheat and rice between them. When the columns on them turned, the powder (or flour) came out.
Umbrella
The invention was finally attributed to Lu Ban's wife. In ancient times, rainy days and hot summer troubled people, and people had to hide under small pavilions and could not go out. There is a legend that Lu Ban built many pavilions around his neighbors for everyone to use, but he still couldn't let people go out freely in the stormy season. Luban's wife then made a lightweight bamboo pavilion with oiled paper-an umbrella, of course, according to the style of the pavilion built by her husband. His wife said to Lu Ban, "The house you built can't be moved. My umbrella can take it around and provide protection in all seasons. " ...> >
Question 5: Lu Xun found that it was another rainy day in his umbrella composition. Looking at the falling raindrops in the sky, I thought of it when I saw the
umbrella that was propped up.
It was also a rainy day, and the sky was overcast. Soon, big raindrops
fell from the sky. The interest class was over, and the students were all picked up by their parents
, leaving me standing there alone, but my father still didn't come to pick me up. At this moment, a big
raindrop fell from the eaves and fell on my head. I was so cold that I felt a tingle. I ran to the store opposite
in the rain. In the storm, I felt the strong wind blowing towards me, and the raindrops hit my
head mercilessly. At that time, I cried, and tears flowed on both sides of my cheeks. I didn't wipe them, leaving them flowing on my face. Maybe this would make me feel better.
It's much warmer in the small shop than outside. I'll stay inside and wait for my father. Fortunately, the shopkeeper
didn't drive me away, otherwise I would have become a "drowned rat"! At this moment, a sky-blue umbrella came into my eyes. It was a very beautiful umbrella with a little lace on it. The animal on it was a rabbit that I dreamed my mother would buy for me. The umbrella handle
is purple, and I like it very much. But I know dad won't buy it for me.
Just then, someone called me, and I looked back. It was Dad!
"Dad, what can I do for you? You used to pick me up early. Why is it so late today?" " "Dad had a meeting in the company today, so he came a little late." "oh". I got on
Dad's battery car and went home. Since then, I haven't seen that umbrella again, and I'm heartbroken. It's another rainy day, and I saw a little blue dot in the distance slowly moving towards me < P > and approaching, and it turned out to be dad! He handed me the umbrella in his hand and said, "Shijia, this umbrella will be yours later!" " I took the umbrella from my father, and my heart was warm, because < P > it was my dream umbrella!
Now, this umbrella has been broken, but I put it in the most conspicuous place in the room. It has always been treasured by me, because it is not just an umbrella, but also contains my father's love for me.
Question 6: The story of Lu Ban's making an umbrella
Long, long ago, there was no umbrella in the world. At that time, it was inconvenient for people to go out In summer, the sun hurts the skin. On a rainy day, get your clothes wet. Lu Ban thought: How wonderful it would be to make something that can shelter from the sun and rain!
One day, the weather was extremely hot, and he was sweating while working. Suddenly I saw many children "plop plop" jumping into the lotus pond to play with water. After a while, a child picked a lotus leaf and put it upside down on his head.
Lu Ban thought it was fun, so he asked them, "What are you doing with a lotus leaf on your head?" The child said noisily, "Master Lu, look, the sun is like a big fire wheel. We are not afraid of the sun with lotus leaves on our heads."
Lu Ban grabbed a lotus leaf, looked at it carefully and looked at it again. The lotus leaf was round, with a vein on one side and a cover over his head, which was light and cool.
Lu Ban's heart lit up. He hurried home, found a bamboo, chopped it into many thin strips, and made a shelf according to the appearance of lotus leaves; I found another sheepskin, cut it round and put it on a bamboo shelf. "All right, all right!" He cried with joy, "This thing can not only keep out the rain and the sun, but also be clever."
Lu Ban's wife heard him yelling, so hurry up.
