Draw a story about the race between the tortoise and the hare.

A. The story of "The Tortoise and Rabbit Race" is very familiar to students. The line segment OD and the dotted line OABC in the figure represent the relationship between distance and time in the "tortoise-rabbit race". Please.

Solution: (1) rabbit; Turtle; 1500;

(2) According to the picture, the rabbit ran back at a speed of 700 meters per minute at first.

1500÷30=50 (m)

The tortoise climbs 50 meters per minute;

(3)700÷50= 14 (minutes)

It took the tortoise 14 minutes to catch up with the sleeping rabbit.

(4) ∫ 48km = 48,000m

∴48000÷60=800 (m/min)

(1500 ~ 700) ÷ 800 = 1 (minutes)

30+0.5- 1× 2 = 28.5 (minutes)

It took the rabbit 28.5 minutes to stop to sleep.

B the picture shows the displacement-time image drawn according to the story of the race between the tortoise and the rabbit. The following statement is true: () A. The race between the tortoise and the hare comes from different places.

A. The tortoise and the rabbit started from the same place, but not at the same time, so A was wrong.

B, in the time of 0-t 1, the displacement of the tortoise and the rabbit is different. From the intersection of the two graphs, we can know that they met once, and B is correct.

C during t 1-t2, the displacement of the tortoise is greater than that of the rabbit, so the average speed of the tortoise is faster than that of the rabbit, so c is correct.

D. As can be seen from the picture, the displacement of the rabbit is greater than that of the tortoise at a certain moment in the middle, but in the end, the tortoise has reached the finish line and the rabbit has not arrived yet, so D is correct.

Therefore: alkaline catalytic decomposition ..

C. Draw a picture to describe the story of the race between the tortoise and the hare.

The first race between the tortoise and the rabbit. The tortoise stepped up training before the game and made full preparations. The rabbit doesn't think so, and doesn't look at his opponent at all. The game has started. The rabbit ran forward and looked back from time to time. Seeing that the tortoise was still crawling slowly, he thought, "The champion is mine. It's okay to have a rest first." So he fell asleep under a tree by the roadside. The final result must be familiar to everyone. The tortoise persisted and won the victory.

Enlightenment: When the enemy is strong and we are weak, don't be discouraged, persevere, seize the opportunity when the opponent makes mistakes and win the final victory. Similarly, for enterprises, in the start-up stage, most enterprises are at a disadvantage in terms of capital accumulation, talent reserve, core technology and brand service. , do not have the strength to compete with large enterprises and well-known enterprises. Therefore, these enterprises must first recognize themselves in the competition with large enterprises.

D. Do you have a complete story and pictures of the tortoise and rabbit race to do your homework? ! !

The rabbit boasted about his speed to the animals and said, "I have never failed," he said. "When I run, no one is faster than me."

The tortoise said quietly, "I want to compete with you." "This is a joke. I can race with you while playing. " Said the rabbit.

The game has started. In a blink of an eye, the rabbit had already disappeared, but he thought he was running fast, so he took the race lightly and fell asleep on the side of the road.

The tortoise walks slowly, but keeps walking. When the rabbit woke up, he saw that the tortoise was near the finish line. The rabbit lost the game.

Moral: Pride goes before a fall; Only by perseverance can we achieve our goal.

It is said that a rabbit races with a fast tortoise. Who will win? It is a turtle, because as I said, it is a very fast turtle. So who will win, the rabbit or the tortoise with sunglasses? The answer is a turtle with sunglasses. Because when the tortoise wearing sunglasses ran to the finish line, the rabbit saw that it was the tortoise that ran very fast. It was a joke, that's all.

E. how to draw the story of the race between the tortoise and the hare?

Draw a running black turtle first, and then a sleeping rabbit. The specific steps are as follows:

1. First draw the outline of the tortoise's head on the far left of the picture, then draw the tortoise's eyes and mouth, and the mouth opens to make a frightened expression.

Precautions:

Beginners suggest to draw with a pencil first, so that mistakes can be easily corrected, and then use neutral strokes after drawing.

Mingming told a story about a race between a tortoise and a rabbit. According to Mingming's story, Cong Cong drew the displacement images of rabbits and turtles as shown in the picture. Please.

(1) The rabbit and the tortoise in the story start from the origin, but not at the same time. The rabbit started later than T 1.

(2) The displacement image of ebony turtle is a straight line. According to the fact that the slope of the displacement image is equal to the speed, we can know that its speed is constant and it is moving in a straight line at a uniform speed.

(3) At t 2 and t 4, the displacement of the rabbit and the tortoise is the same, which means they met in the same place, so they met twice in the competition.

(4) Read from the picture that the rabbit hasn't arrived when the tortoise reaches the finish line, so the tortoise reaches the finish line first.

Answer: (1) The rabbit and tortoise in the story are in the same place, but they don't start at the same time. The rabbit started late.

(2) The tortoise moves in a straight line at a uniform speed.

The rabbit and the tortoise met twice in the competition.

(4) The tortoise reached the finish line first.

G. The complete story of the race between the tortoise and the hare

One day, the rabbit and the tortoise raced. The rabbit laughed at the tortoise for crawling slowly, and the tortoise said that he would win one day. The rabbit said, let's start the game now. The rabbit ran quickly and the tortoise crawled desperately. Soon, the rabbit and the tortoise are far away.

Rabbit thinks this game is too simple. It needs to sleep for a while, thinking that even if it wakes up, the turtle may not be able to catch up with it. On the other hand, the tortoise has been crawling. When the rabbit woke up, the tortoise had reached the finish line.

(7) Painting Story: Tortoise and Rabbit Race Extended Reading:

Moral:

Modesty makes people progress, while pride makes people lag behind. Do things in a down-to-earth manner, don't give up halfway, and you will succeed.

Zhi Nuo, a famous ancient Greek philosopher, did ask such a question and thought that "Achilles could not catch up with the tortoise". Achilles is the fastest fast leg in Greece. It is said that after hector, the general in the Trojan War, killed Patrockler, Achilles stabbed hector, who was defeated and fled, to avenge his friend.

It is such a "fast tortoise", but Zhi Nuo thinks he can't catch up with the tortoise. Zhi Nuo suggested that the tortoise came first, and Achilles had to reach the starting point of the tortoise before he could catch up with it. When he caught up with the tortoise, it had been crawling for a long time.

So Achilles had to catch up with this road again, when the tortoise climbed forward for a while. In this way, he kept chasing. Although the distance is getting closer and closer, Achilles still can't catch up with the tortoise.

Aristotle once brilliantly analyzed Zhi Nuo's argument. He said: "It is wrong to think that the leader in sports can't catch up, because it can't catch up when it is ahead, but if it is allowed to cross the prescribed limited distance, it can also be caught up."

Aristotle pointed out a key problem of Zhi Nuo's viewpoint, that is, he first gave a premise that the fastest distance should not exceed the specified limited distance. In fact, the fastest can cross a limited distance, thus surpassing the slowest.

Obviously, Zhi Nuo only recognized two different time and space points that were separated from each other, but denied the mutual connection between them, thus denying the authenticity of the movement. This undoubtedly emphasizes the infinite separability of time and space one-sidedly, which is a metaphysical view.

H. Make up a fairy tale of the race between the tortoise and the hare in 300 words.

In the race between the tortoise and the hare, the hare was defeated by the tortoise for being sleepy. The rabbit was worried and thought, am I really not as good as the tortoise? From then on, the rabbit made up his mind not to sleep and planned to have a second race with the tortoise.

On this day, the rabbit looked for the tortoise and wanted to have another race with it. Suddenly, the tortoise jumped out of nowhere and frightened the rabbit. The rabbit said to the tortoise, "Tortoise, let's have another game!" " The tortoise heard this and thought, "The rabbit lost, but I won the previous game." He proudly said to the rabbit, "well, let's have another game." The rabbit heard this and thought, "The tortoise is sure to lose this time." They came to the place where the competition was held, and prepared to do it according to the original method. The game is about to start. The tortoise found something was wrong and said to the rabbit, "Rabbit, who?" The rabbit, eager to compete, had a brainwave and thought of his neighbor's pony. So they invited the pony. The enthusiastic pony shouted, "Are you ready ... go." Just as he shouted, the rabbit had run far and the tortoise was still crawling slowly.

After a long time, a big "?" Appear in the turtle's mind. No, why did the rabbit run far away and didn't see the original tree? The tortoise shouted, "Rabbit, why didn't you see the original tree after running so far?" When we used to compete, the trees weren't that far away? "The rabbit listened and thought: Will the tortoise cheat me? But its voice seems to be in a hurry. So the rabbit stopped and shouted to the tortoise, "Yes, I haven't seen a tree after running so far!" "What's the matter?" The confused rabbit had to turn around and look for the shadow of the tree with the tortoise. After searching for a long time, they didn't even see a small tree, but they found dead stumps one by one. It turns out that all the trees have been cut down by humans. They had to leave their familiar places sadly and go home separately.

In this way, there is no competition between the tortoise and the rabbit, so you can't see the difference. But they made up and decided never to compete, but to protect every tree in the forest together.
