Reading materials for animal mathematical geniuses
Many animals are not as dull as people think. They are not only clever, but also know how to calculate, measure or count. Some people even do math? Genius? .
② There are considerable mathematical principles in the living habits of animals. For example, when a snake crawls, it follows a sine function diagram. Its spine is like a train, connected from section to section, and there is a lot of room for activity between sections. If the plane coordinates of each node are fixed and the starting point is taken as the coordinate origin, it is found that the snake moves regularly according to the sine function curves of 30 degrees, 60 degrees and 90 degrees.
The counting ability of small ants is not inferior. Winston, an English entomologist, conducted an interesting experiment. He cut a dead grasshopper into small, medium and large pieces. The middle piece is bigger than the small piece 1 times, and the big piece is bigger than the middle piece 1 times. Put them next to the ant nest. B About 10 minute, 20 ants gathered around the small grasshopper, 5/kloc-0 ants gathered around the middle grasshopper, and 89 ants gathered around the big grasshopper. The distribution of the number and intensity of ants is consistent with the size ratio of grasshoppers, and its accuracy is amazing.
Scientists have found that cormorants can count. In some parts of China, cormorants fish, and their owners tie cormorants' throats with strings. When the cormorant catches six fish, there is a long-term agreement between the owner and the cormorant, allowing them to eat the seventh fish. Scientists have noticed that if fishermen occasionally make mistakes and do not untie the rope around the cormorant's neck, the cormorant will not move. Even if fishermen beat them, they won't go out fishing. They know that the seventh fish should be their own income.
(5) Spider knot? Gossip? Grid is a complex and beautiful octagonal geometric pattern, and it is difficult for people to draw a symmetrical pattern like a spider's web even with drawing tools such as rulers and compasses.
6. Dr. Hansel, an American animal psychologist, first gave the animals wrong information during the experiment, and then observed their reactions. He once distributed two bananas to 100 Caribbean wild monkeys every day for a month, and then suddenly it was reduced to 1 banana. At this time, 96% of wild monkeys will watch bananas once or twice, and a few monkeys will even scream in protest. American animal behavior researchers have done a similar experiment: first, let eight chimpanzees eat 10 banana at a time, and so on many times. One day, the researchers suddenly gave each orangutan only eight bananas. As a result, all the black gorillas refused to go away until the owner made up 10 bananas. It can be seen that both wild monkeys and chimpanzees have mathematical minds.
7. For a long time, everyone, including scientists, has always believed that only human beings have mathematical concepts and computing ability, but through observation and experiments, we know that the wisdom of animals can not be underestimated.
Mathematical geniuses read animal themes
Question 1 What animals with mathematical minds are introduced in the full text? What is the difference between them? Mathematical genius (5 points)
Question 2: How to explain the underlined sentences in the text? What's the role? (6 points)
For example, when a snake crawls, it follows a sine function diagram.
B About 10 minute, 20 ants gathered around the small grasshopper, 5/kloc-0 ants gathered around the middle grasshopper, and 89 ants gathered around the big grasshopper.
Question 3? Even if people use rulers, compasses and other drawing tools, it is difficult to draw a pattern as symmetrical as a spider's web? Just hit the nail on the head, okay Can it be deleted? Why? (3 points)
Question 4? The wisdom of animals should not be underestimated. ? After reading the above, I believe you have a new understanding of animals. Please write a propaganda slogan, calling on people to protect and treat animals well. (Rhetoric is required) (2 points)
Mathematical geniuses in animals read answers.
Question 1 When the snake crawls, take the sine function diagram; Ants have superb counting skills; Cormorants can count; Spider knot? Gossip? The grid is a complex and beautiful octagonal geometric pattern; Wild monkeys and chimpanzees have mathematical minds and can measure.
Sentence 2A: For example. The example of snakes shows that there are quite a few mathematical principles in the living habits of animals.
B: List the numbers. Specifically, the number and power distribution of ants are highly consistent with the proportion of grasshopper block size, which highlights the fast and accurate ant counting. (It is pointed out that the interpretation method is 1 and the interpretation function is 2).
Question 3 cannot be deleted. ? Even if? Used together, it represents a hypothetical relationship, makes a virtual comparison between people drawing with tools and cobwebs, and highlights the symmetry of cobwebs.
Example 1: Get close to animals and enjoy life. Example 2: There is only one earth for human beings, but there are not only human beings on the earth! (The answer is not unique)
