Mysterious pond

I never get bored when I stare at the pond. In this little green world

In the room, I don't know how many busy little lives will be endless. By the muddy pool, piles of black can be seen everywhere.

Our tadpoles are playing and chasing in the warm pool water; Red-bellied salamanders also use their wide tails as rudders.

Swaying and moving slowly; In the reed grass, we can also find groups of silkworm larvae.

The children each hid their bodies in a small sheath made of dead branches-this small sheath was used to defend against natural enemies and various intentions.

For an unexpected disaster.

Deep in the pond, the water beetle is jumping briskly, with a bubble at the top of its front wing. This bubble

It is used to help it breathe. It has a chest wing on its chest, shining in the sun, like wearing a mighty big one.

The shining breastplate on the general's chest. On the water, we can see a bunch of shining "clam spiders".

Twisting happily, no, that's not a "clam spider". Actually, it was a black bean bug having a party! Stay away from here

Not far away, there is a team of pool rays swimming here, and their side strokes are like sewing needles in a tailor's hand.

So fast and powerful.

In this place, you will also see the water scorpion, which crosses its limbs and swims leisurely on the water.

That posture and expression seem to be the greatest swimmer in the world. And dragonfly larvae, dressed in mud.

There is a funnel at the back of the coat. Whenever it squeezes water out of the funnel at a very high speed,

With the reaction of water, its body will rush forward at the same high speed.

At the bottom of the pond, there are many quiet and stable shellfish. Sometimes, small snails walk along the pond.

The bottom of the sea climbed to the shore gently and slowly, carefully and slowly opened their heavy eyelids, blinked and was full of curiosity.

Look forward to this beautiful underwater paradise and enjoy breathing some land air at the same time; Leeches gave in to their conquest.

Things, constantly twisting the body, a smug look; Thousands of animals are rhythmic in the water.

Twisted ground, in the near future, they will become mosquitoes and bad people called by everyone.

At first glance, this is a stagnant pool. Although it is not more than a few feet in diameter, it is bred by sunlight.

At present, it is like a huge mysterious and colorful world. How to impress and stimulate children's curiosity.

Ah! Let me tell you how the first pond in my memory deeply attracted me and aroused my curiosity.

Heart.

My family was poor when I was a child. Except for a house inherited by my mother and an abandoned small garden,

There's almost nothing left. "How will we live?" This serious problem often hangs on my father.

Mom's mouth.

Have you heard the story of "Thumb"? Thumb hid under his father's low stool to eavesdrop on his father's speech.

Some embarrassing conversations about life that my mother said. I'm like that thumb. But I'm not like him

So I can hide under the stool. I pretended to be asleep on the table and eavesdropped on their conversation. lucky

Fortunately, what I heard was not as chilling as what Thumb Dad said. On the contrary, it is

This is a wonderful plan. After listening to this, I feel an indescribable joy and relief.

"If we keep a flock of ducklings," said mother, "we will certainly get a lot of money in the future. We can buy some.

When the grease comes back, let Henry take care of them and fatten them every day. "

"Great!" Father said happily, "Let's try."

That night, I had a good dream. I strolled to Chi Pan with a group of lovely ducklings. they

They are all dressed in bright yellow clothes, playing in the water and taking a bath. I smiled and watched them take a bath, and I was patient.

Wait for them to take a bath, and then walk home with them slowly. On the way, I found one of the ducklings tired.

Just pick it up carefully, put it in the basket and let it sleep sweetly.

Unexpectedly, just two months later, my dream came true: there are 24 furry ducklings in our family.

Son. Ducks can't hatch eggs by themselves. Hens often hatch eggs. The poor old hen can't tell whether it is her own flesh and blood.

Is another family's "wild child", as long as it is round and almost like an egg, it is happy to hatch, and

Treat the hatched little creatures as their own children. Two black hens are responsible for incubating our ducklings.

One of them belongs to our own family and the other is borrowed from our neighbor.

Our black hen plays with the ducklings every day and tirelessly plays games with them to make them

Grow up happily and healthily. I put some water into a wooden bucket about two inches high, and this wooden bucket became the ducklings'.

Swimming pool. As long as it is sunny, the ducklings always bathe in the warm sunshine while bathing in the wooden bucket.

The play is so beautiful, harmonious and comfortable that all the black hens next to it are envious.

After two weeks, the little wooden bucket gradually failed to meet the requirements of the ducklings. They need a lot of water,

In this way, they can turn around and jump freely inside. They also need many shrimps, crabs and bugs.

Class as their food. These foods are usually stored in a large number of intertwined aquatic plants, waiting for themselves.

Go hunting. Now I feel that getting water is a big problem. Because our family lives on the mountain, we brought a lot of water from the foot of the mountain.

It is very difficult to get up. Especially in summer, we can't drink water happily, so how can we care about those small ones?

Where are the ducks?

Although there is also a well near our home, it is semi-dry, and four or five neighbors take turns to use it every day.

Yes, and the donkey kept by the school principal always greedily gulps down the well water.

The water was quickly drained. It was not until a whole day and a night passed that I saw a well water gradually rising and gradually recovering.

Go back to the way it was. In such a difficult situation of water shortage, we poor ducklings naturally have no right to swim freely.

However, at the foot of that mountain, there is a gurgling stream. It's a natural paradise for ducklings. But from our home

To get to the stream, we must cross a country road, but we can't take that road because we are on that road.

I will probably meet some fierce cats and dogs, and they will not hesitate to break up the team of ducklings so that I can't put them away.

The children are together again. So, I have to find another way out. I remember there was a big one not far from the mountain.

Grass and a big pond. It is a very desolate and remote place, without any interference from cats and dogs, indeed.

It can be a paradise for ducklings.

On the first day as a shepherd boy, I was very happy and comfortable. But there is one thing that makes me uncomfortable, and that is * * * naked pairs.

My feet are getting blistered. I can't take the shoes out of the box because I run too much. Shuang Bao.

Expensive shoes can only be worn on holidays. My feet kept running in the rocky weeds, and there were more and more wounds.

It's huge.

Ducklings' feet don't seem to stand such a toss, because their webbed feet haven't fully grown out, and they are far from hard enough.

They are walking on such a mountain road, and from time to time they make a cry of "quack-quack-",as if asking me to allow them.

Give them a rest. At this time, I had to meet their requirements and call them to rest in the shade.

Otherwise, I'm afraid they will never have the strength to walk the rest of the way.

We finally reached our destination. The pool water is shallow and warm, and the mounds exposed in the water seem to be one after another.

An island. As soon as the duckling got there, he flew to the shore to look for food. After eating and drinking, they will

Take a bath by the water. When taking a bath, they often stand upright, with their forearms buried in the water and their tails pointing.

In the air, like ballet in diving. I like the graceful movements of ducklings. When I am tired, I look at the water.

Other scenery.

What is that? On the dirt, I saw several ropes intertwined, thick and loose, dark and smoky.

Full of soot. If you see it, you may think it is wool taken from some socks. So I thought:

Maybe a shepherdess was knitting a black wool sock by the water, and suddenly she found that she couldn't walk without a few stitches.

After editing and complaining for a while, she decided to tear it all down and start over. When she was impatient, she just

Just throw all the broken parts into the water. This speculation seems reasonable.

I went over to pick up a piece and put it in my palm to observe it carefully. I didn't expect this thing to be sticky and slippery, so I suddenly went from

I slipped through my fingers. I made great efforts, but I couldn't catch it, and some knots of the rope suddenly dispersed.

Then, from the inside, I ran out of the little bead, only the size of a needle tip, dragging a flat tail behind me, and suddenly I

I know them. They are the larvae of an animal I am familiar with. This is the frog's larva-tadpole.

I also saw many other creatures here. One of them has been spinning on the water, and its black back

The department sparkled in the sun. Every time I reach for them, they seem to foresee the danger.

I ran away without a trace before I touched them. I want to catch a few and put them in a bowl to study them carefully, but unfortunately I can't catch them.

For them.

Look! In the depths of the pool, there is a mass of green and dense aquatic plants. I gently pushed away a bunch of aquatic plants and saw Li.

There are many water droplets carved on it, scrambling to float to the surface to form a big bubble. I think it must be under this thick grass.

What strange creatures are hidden. I continued to explore and saw many shells as flat as beans, surrounded by several.

Vortex ring; There is a bug that looks like wearing feathers; There is also a small creature that dances with soft fins, just like wearing porcelain.

Li's skirt is dancing. I don't know why they keep swimming around like this, and I don't know their names.

I can only daydream about this mysterious pool.

The pool water slowly flowed into the nearby fields through small channels, where there were several alders, and I found them there again.

I saw a beautiful creature. It's a beetle, as big as a walnut, with some blue on it. That blue is very valuable.

Being convinced reminds me of a beautiful angel in heaven. Her dress must be such a beautiful blue. I'm pregnant.

I piously picked it up gently, put it in an empty snail shell and stuffed it with leaves. I'm going to put it

Take it home and enjoy it.

Then my attention was attracted by something else. Clear and cool spring water keeps flowing down from the rocks.

Come down and moisten the pond constantly. The spring water first flows into a small pool and then flows into a stream. I see

It suddenly occurred to me that it would be a pity to let the stream flow quietly. Consider it a little bit.

Waterfall, mill. So, I began to make a small mill. I made a shaft out of straw and two small stones.

Building blocks support it, and it will be finished soon. This mill was very successful, but unfortunately I didn't take my little friend with me at that time.

Yes, only a few ducklings came to appreciate my masterpiece.

This small success greatly stimulated my creative desire, which was out of control. I'm going to build another small water.

Dam, there are many rocks that can be used. I patiently selected the stones that can be used to build the dam. Suddenly, I

However, I found a miracle, which made me unable to continue to build the dam.

I opened a big stone, and there was a hole as big as a small fist, and clusters of auras emanated from the hole.

It's like a string of diamonds shining in the sun, and it's like hanging down from the lights in the church.

A string of glittering and translucent beads.

What a splendid and beautiful thing. Reminds me of the legend of the dragon told by the child lying on the hay in the threshing floor.

This story. The dragon is the guardian of the underground treasure house. They guard countless treasures. Now it flashes in front of my eyes

Will these light things be the crowns and jewels mentioned in the myth? Are they hidden in these bricks?

Did you win? Among these rubble, I can collect a lot of shiny rubble, which is a treasure given to me by the dragon.

Treasure! I seem to feel that the dragon is calling me and giving me countless gold. I saw a lot under the gurgling spring.

Golden particles, they all stick to a piece of fine sand. I leaned down and observed carefully, and found that these gold grains followed in the sun.

Is this really gold, jumping around with the spring water? Is it really gold that can be used to make twenty francs gold coins? For a poor man,

How precious this gold coin is for a poor family!

I gently picked up some fine sand and put it in my hand. There are many luminous gold particles, but the particles are very small.

You must soak straws with saliva before you can touch them with it. I have to give up this troublesome job. I think it must be.

There is a large piece of gold hidden deep in the rock, which can wait until I blow up the mountain later. These little gold particles

It's so obscene, I'm not going to pick them!

I continued to break the masonry to see what was inside, but what I saw was not a jewel, but a stone.

A bug crawled out of the ruins. Its body is spiral, with scars from one part to another, just like a snail in the rain.

The ancient sky wall climbed out of the wall, and the knotted place was particularly vicissitudes and strong. I don't know about them.

Sample into these bricks, also don't know what they are doing.

In order to commemorate the "treasure" I found, driven by curiosity, I put bricks in my pocket and stuffed them full.

It is full. At this time, it was getting dark and the ducklings were full, so I said to them, "Come, come with me, we want it."

Go home. "

My mind is full of fantasies, and the pain in my heel has long been forgotten.

On the way back, I thought of my blue beetle, the beetle like a snail, and those dragon houses.

A present. But as soon as I stepped into the house, I woke up, and my parents' reaction made me very disappointed. They saw it.

My bulging pocket is full of useless bricks and stones, and my clothes are almost torn by bricks and stones.

"Son, I told you to watch the ducks, but you just went to play. Are you picking up too many bricks and stones?

Aren't there enough stones around our house? Throw these things out quickly! "My father shouted at me.

I had to obey my father's orders and put all my treasures, gold grains, horn fossils and sky-blue beetles.

Throw it in the gangue pile outside the door, my mother looked at me and sighed helplessly.

"Son, you really embarrass me. I won't blame you if you bring some vegetables back, at least.

You can feed it to rabbits, but this kind of gravel will only damage your clothes. This poisonous insect will only sting your hand. they

What benefits can it bring you? Idiot! Something must fascinate you! "

Poor mother, she's right. One thing really fascinates me-the magic of nature. number; amount; how many; how much

Many years later, I realized that the "diamond" by the pond was actually a crystal; The so-called "gold particles" did not exist originally.

But that's mica, not a treasure that the dragon gave me. Still, for me, that pond has always been

Keep it attractive, because it is full of mystery. In my opinion, those things are far more attractive than diamonds and gold.

Glass pond

Is there a small pond in your house? In that small pond, you can observe the creatures in the water at any time.

Every part of life. Not as big as the outdoor pond, and there are not many creatures, but these are just for viewing.

Inspection provides favorable conditions. Moreover, there will be no pedestrians disturbing your focused observation. Actually, it's nothing

Arabian nights, this is easy to achieve.

My indoor pond was built with the cooperation of a blacksmith and a carpenter: first, I made a pool frame with iron bars and put it in wood.

On the pedestal. The pool is covered with a movable board, and the bottom of the pool is made of iron with a row on it.

A small hole in the water. The pool is surrounded by glass. This is a well-designed glass pool, which is placed in my window.

Its volume is about ten to twelve gallons.

I put some greasy things in the pool first. It is a heavy thing with many small holes on its surface.

It looks like a coral reef. The lump is covered with a lot of green and fluffy moss, which can keep the water clean.

Why? Let's have a look.

Animals in the pool, like us in the air, have to breathe in fresh smells, and at the same time, they have to emit waste gas (carbon dioxide).

These waste gases are uncomfortable to breathe. On the other hand, plants inhale carbon dioxide. So the water plants in the pool

Absorb this kind of non-breathable waste gas, and release oxygen that animals can breathe after certain work.

If you stay in a sunny pool for a while, you can observe this change. On coral reefs with aquatic plants,

The shining starlight is like little pearls dotted on the lawn, and green seedlings are everywhere. these

Pearls disappear and appear one after another, and suddenly fly away on the water, as if they were underwater.

There was a small explosion and a series of bubbles came out.

Aquatic plants decompose carbon dioxide in water to get carbon, which can be used to make starch. Starch is a biological cell.

Something indispensable. The waste gas emitted by nutritious aquatic plants is fresh oxygen. Part of the oxygen is dissolved in

In the water, the creatures in the water breathe, and some of them leave the water and run into the air. What you see outside is like pearls.

Bubbles are oxygen!

I looked at the bubbles in the pool and daydreamed: many, many years ago, the land just left the ocean.

At that time, grass was the first plant. It spit out the first breath of oxygen and provided breathing for living things. So all kinds of animals came out.

Now, generations of reproduction and changes have formed today's biological world. My glass pond seems to

Tell me a story about a planet sailing in space without oxygen.
