Inscription: I am Ann krylov (1769- 1844) is the most outstanding Russian fable writer. Krylov wrote 203 fables in his life. Krylov believes that fable is a popular and popular literary genre. The metaphorical nature of fables allows the author to easily express the views that the rulers are not allowed to say. Belinsky, a great Russian literary critic, said: "krylov's fable is not a simple fable, but a novel, a comedy, a humorous close-up and a bitter satirical literary work. In short, this is not a simple fable. " Starting today, read krylov's fables as your daily homework. Starting with the most familiar swans, barracuda and prawns, this fable was once included in the primary school Chinese textbook with the title Swan, Barracuda and Shrimp.

Krylov's fable reads as follows:

If the partners are inconsistent, the cause will be bad; Although I have been worried, I still haven't made any progress.

One day, Parker, Shrimp and Swan went out to tow a car on the road, and the three guys shouldered the burden together. They push hard with their feet, and the veins stand out. No matter how they dragged, pulled and pushed, the car was still in place and did not move a yard. It's not that the car is too heavy to move, but there are other reasons: the swan is trying to lift it to the sky, the shrimp is dragging backwards step by step, and the pike is pulling to the pond again. I don't know which is right or wrong, and I don't want to delve into it; All I know is that the car is still parked in the old place.

Fables are generally reasonable. The truth of this fable is clearly stated at the beginning: "If the partners are inconsistent, the career will be bad."

Barracuda, shrimp and swan are working together to drag a car off the road. None of them cheated and played tricks, they all tried their best, but why didn't the car move at all? I'm not going anywhere! One pulls up, one pulls back and one pulls down. According to the principle of mechanics, the resultant force formed by forces not in the same direction is less than that formed by forces in the same direction, so the car naturally cannot move.

Deep thinking, since the three initial goals are the same, why do they act in their own way?

Swan, pike and shrimp are three kinds. Swan flies in the sky, but can't fly in the water. Barracuda and shrimp swim in the water, but they can't swim to the sky. The living environment of pike and shrimp is similar, but their habits are different. The fish swims forward by swinging its tail fin, while the shrimp swims backward by rowing its legs like wooden paddles frequently, and its body is slowly pushed forward. Moreover, when the shrimp is frightened, its abdomen will flex flexibly and its tail will paddle down and forward, so that it can keep jumping back.

Birds of a feather flock together, different species get together, and their ways of thinking and action are very different. How to coordinate?

So some couples live together and break up, and some partners go their separate ways.

There is some doubt about why the word "Parker" in the title has become the word "Parker" in the text. Both pike and pike are fish, but they have different personalities. "Parker" is fierce, while Parker is gentle.
