The composition of frog heart.

We frogs are amphibians, adults have no tails, eggs are laid in water, fertilized in vitro, hatched into tadpoles, and breathed through gills. After the mutation, adults mainly breathe through the lungs.

We are slim, with inconspicuous necks and no ribs. The claws can't turn flexibly, but the limbs are muscular and jump far.

Because we frogs feed on insects and other invertebrates, we must live by water. We are almost all experts in eliminating pests in forests and farmland, so we are good friends of mankind. Please love and protect us and the water we live on, and we will try our best to eat more pests. This is the voice of our frog.

Xiaoqing duckling revealed how to protect frogs in this fairy tale of frogs. One day, I saw a stall on my way home, surrounded by many people, so I leaned in curiously to see it.

I don't know if I didn't see it, but I was shocked when I saw it.

There are more than a dozen big nets on the ground! Each net contains a big frog and a small frog. The frog in the net looks listless, with his mouth wide open, his head hunched, and his protruding eyes half narrowed.

Seeing this scene, I remembered the alert frog that I saw by the pond before, which was very different from the frog I saw today.

I looked at their dull and frightened eyes and felt that they were asking us for help, as if to say to us, "I am a beneficial animal, let me go!" " "When the stall owner saw me standing here for a long time, thinking that I wanted to buy a frog, he solemnly said to me," Little friend, do you want to buy a frog? Very fat, the meat is fragrant and tender, and it is still wild. I'm sure you want to eat it again after the first time.

"When people around me heard that it was wild, they reached out to buy frogs. In a short time, all the frogs in a dozen nets were robbed.

Seeing this, I have a big question in my heart: Why do we have to kill frogs because they have contributed to us? Frogs are experts in catching pests. Frog catches pests with its long and wide tongue. The root of the tongue grows in front of the mouth, and the tip of the tongue diverges backwards. There's a lot of mucus on it. Whenever small flying insects fly by, they rush.

Jump up, open your mouth, quickly stick out your long tongue and eat the pests at once.

Frog is a hero to protect farmland, and we should all take good care of it.

I am a little frog who lives by a stream in the suburbs.

Look, how beautiful my home is! It is sunny and beautiful here, and there is a crystal clear stream nearby, singing and running forward; There are several tall and straight willows on both sides of the stream. Miss Liu's hair is thin and long, and there are many green hair clips. Wild flowers and weeds on the grass are enjoying the moisture of nature leisurely ... "Hmm!" I took a deep breath. "And this fresh air!" However, the good times did not last long.

This land is beautiful, and many people come here for picnics.

They eat, drink and have fun here, and don't throw empty cans and peels.

Over time, it becomes, there is an unpleasant smell in the air, the stream becomes smelly and muddy, and it becomes a world full of mosquitoes and flies. All the animals living here have jumped away, and the flowers and trees are all sick ... no, I can't stand it, so I have to pack up and move.

As soon as I left home, I quickly covered my nose and jumped carefully.

Suddenly, I saw a small umbrella moving forward in the stream, covering my nose and mouth and shouting at it: "hello!" " Who's in the water? "I saw the little red fish with a small umbrella, slowly exposed, immediately cover your mouth and try very hard to breathe.

"Oh, it's a little red fish! Are you moving too? " I asked.

"Yes, you see how serious the pollution here is! It's hard to live here! How beautiful it used to be here! The stream is clear, the trees are lush, the air is fresh, the birds are singing and the flowers are fragrant, but ... but now ... "The little red fish sobbed.

"Little red fish, don't cry.

Who is to blame for this? This is not their human masterpiece! Human beings only know how to be good to themselves, how can they consider the consequences? Come on, little red fish, let's leave this destroyed place! Say that finish, we left together.

How I hope that mankind can realize the seriousness of environmental pollution and take effective measures.

Don't kill animals, care for flowers and trees, protect animals, and start from the little things around you.

Give the earth a thorough "big bath" and put on clean and beautiful new clothes.

Give us a green, free and beautiful home! ...

What does the little frog reveal in this fairy tale? What does the little frog confide in this fairy tale: protect the frog and care for the environment.

I have lived in a beautiful river since the frog's voice became sensible. The river is clear and cool and the sand on the beach is thin and soft.

The grass on the river bank is lush, and colorful flowers are quietly blooming in the grass.

Sister Butterfly and Sister Bee often come here to play happily with us.

By the way, there are aunt fish and aunt shrimp. We sang together, played hide-and-seek and lived a carefree life.

Mom and dad go out early and come back late every day to help farmers catch pests, which has won unanimous praise from farmers' uncles.

In summer, many naughty children swim barefoot and naked in the river and have a water fight. Happy laughter echoed on the river for a long time.

However, I don't know from which day on, the water in the river gradually turned black and gave off an unpleasant smell.

One day, I just put my head out of the water to get some air, and a plastic bottle flew in front of me and knocked me unconscious.

I woke up slowly and found a lot of rubbish floating around, including white lunch boxes, packaging bags of various colors, and stems and leaves of some vegetables. Usually bright rivers become turbid.

I hurriedly jumped to the shore. I couldn't believe my eyes when I saw all this.

Since then, I have never seen Sister Butterfly and Sister Bee again, and even my favorite children often pass by here with their noses covered.

Many of my friends died slowly because they drank this unclean water.

My parents had to take me to a small puddle to take refuge.

Soon, people who are usually gentle and kind also came to arrest us and said that they would sell us to hotels as snacks.

Poor mom and dad were taken away by them on the way to find food. It is said that they are kept in iron cages, waiting to be eaten as delicacies.

I live alone now, and I have to be on tenterhooks every day ... alas! I have to hide, but where can I hide?

I like small animals very much, especially frogs.

Frogs are chubby, but they are also very long, and some are seven or eight centimeters long.

They were dressed in yellow-green clothes, showing their white bellies.

Their heads are wide and flat, like a triangle.

It has a pair of big round eyes, a big mouth and a small nose on its head.

Frogs like eating pests best.

Flies, mosquitoes, sandflies, grasshoppers.

It likes to eat everything.

Frogs are always squatting by the pool with big eyes, waiting for a good meal.

As long as there is a bug flying in front of his eyes, it will suddenly jump up, stretch out its tongue and roll it into its mouth.

Then crouch there and wait for the next prey to appear.

Frogs are really good at catching insects. I heard the farmer's uncle say, "According to statistics, a frog can kill at least 10,000 pests a year.

"Frogs are our good friends and farmers' uncles' good helpers.

I like frogs.

...

Frogs like to live in ditches, ponds, streams, rice fields and swamps. They have two long and strong hind legs and can jump 20 times their own length. They are famous long jump champions. This frog has two big eyes, like two crystal clear glass balls, bulging high, blinking and very smart. When the frog entered the water, it swam happily. It has long webbed feet. It really looks like a swimmer. In the rice field, frogs are contending enthusiastically, as if holding a lively concert. Frog kicks and jumps on its hind legs, quickly curls up its hind legs, jumps high, sticks out its tongue and sucks flying insects like a vacuum cleaner. In the field, frogs croak together, quack quack quack quack quack quack quack quack quack quack quack quack quack quack quack quack quack quack quack. Drum after drum. Wow, jujube, jujube, jujube, jujube, jujube, you will often hear this charming voice on summer nights. This is the song of the tireless musician Jujube Frog. Frogs jump in every field, and their mouths are like talking and singing. There are many kinds of them, some are green on their backs, some are flowers, and some are brown, but the skin under their stomachs is uniform white. Some frogs are as big as adults' fists, while others are as small as children's fingers. They shouted impudently in rice fields, ponds and roadsides, so that at least one-third of their bodies were blistered under their mouths. They have been hiding in the soil for a winter, and they have too many emotions to vent. People in the village don't call them frogs, they call them frogs. The tadpoles turned from frog eggs have infinite attraction for some children. They crouched beside them. Look at the way they swim in the water. It's silly. They ignore their own existence, but their faces are dumber than tadpoles. They fished them in their hands and looked around, but they never understood that when it was dark, they would change color, legs would grow under their stomachs and their long tails would disappear. They asked the adults, who vaguely said that they were originally fish in the water because they wanted to see the world on the water. My appearance has changed. Environmental protection composition: I am a happy little frog, and my home is in a clear stream. Water is as clear as a mirror. I have many lively and lovely friends who come to play in the stream every day, and some children on the shore often come to the river to wash their feet and play. There are more than a dozen frog families in this stream, and they have to help farmers catch insects every day. Life is very comfortable! However, suddenly one day, I found that the water in the river became more and more dirty and smelly. When people were walking by the river, they strode by, covering their noses, and even the crickets that had dug holes under the trees ran away. The originally clear water became turbid. I was wondering why the river suddenly became dirty. I saw many partners wrapped up and a huge mineral water bottle floated head on. It's too dirty here! I heard that your mom and dad were treated as snacks! I'm so sad! I've looked for a place for me everywhere. I'm still in a small pond that can only hold one frog. I don't know what to do yet! Gung! Gung! Now I know that it is those ignorant people who throw confetti, mineral water bottles and other rubbish in the river. I want to say to mankind: "Please stop littering, because it will pollute more rivers.". If the water in the world is polluted, you humans will have no water to drink. You will die of thirst if you don't drink water. So please protect the environment!

Little Frog's Idea A little frog was born in a dark and wet well. He wants to jump out and see the world there and find an outside friend, but he can't. Why? It can't jump because the well is too deep. One day, a bird flew to the bottom of the well to drink water. After drinking the water, the bird chatted with the frog. The bird asked in surprise, "Who are you?" Why haven't I seen it? "The little frog said listlessly," I'm a frog, and you? The bird said, "I am a bird." You live in such a terrible place. Don't you feel lonely? "The little frog shook his body and said," Lonely. The bird flapped its wings and said, "Otherwise, I'll take you out to have a look." "When the little frog heard that he was going out, he jumped around happily. He quickly said to the bird, "OK, OK." So the little frog went to a new home-the pond under the bird's tree. He lived for a few days and found that the bird had lived for a few days. The bird tells it that there are lions and tigers here, and one day they want to eat a small animal. Because everyone can't help it, they will all be eaten. The little frog thought about it, rolled his eyes and told the bird a way. The way is this: the rabbit spreads some grass on the wellhead where the little frog lives as a disguise, and then puts a big piece of meat on the wellhead. Then the rabbit said to the lion, "I have a lot of meat, all you have to do is." "

Just get rid of the tiger in the same way.

"Everyone tried, and it really worked. The small animals all praised the frog as a clever boy.

Hearing this, the little frog felt that My Sweetie was in his heart.

Please listen to my heart and write 800 words. ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ... communication is a bridge between hearts, and communication is that two people listen to each other's voices.

With the growth of age, the communication between us and our parents is less and less, replaced by the door closing sound that shakes our hearts after dinner, which is the silence and quarrel between us and our parents.

Without communication with parents, there will naturally be a "generation gap" between parents, an invisible gap.

Some people say, "The older generation will never understand what the younger generation did, and the younger generation will never understand what the older generation said.

"Different times, different thoughts and different ages have caused differences between us and our parents. I think everyone is deeply touched by this? My parents have always attached great importance to my academic performance. In fact, I know they are also good for me, but sometimes I need a space of my own.

I want to have my own study time, I want to have my own rest time ... but my thoughts are just hidden in my heart, and I didn't tell my parents that I was afraid they would be angry, saying that I didn't want to study hard and wouldn't listen when my wings grew hard ... Mom and Dad, I have learned to arrange my own time. You can rest assured that I know what my task is. As a student, I certainly know that my first task is to study, but I also need to rest and play. After all, I'm still a child ... Mom and Dad, just because I didn't do well in the exam once doesn't mean I'll never do well. I know I'm in a bad mood, so don't blame me again. Don't give me a straight face just because I didn't do well in the exam once. My mood will only get worse, mom and dad. Just find me a cram school. I know you want me to learn better, but I hope you can listen to my thoughts. I need you to listen patiently ... mom and dad, I will be a good boy, I will do everything carefully, and I will honor you well. Just mom and dad, I hope you can trust me more, give me more opportunities and have enough time to prove it to you. Let you see how great your children are ... mom and dad, in fact, I am also very good, but you didn't find it. Please don't talk about what the children of the Zhang family have achieved in front of me. I know you want me to be as good as others, but you know what? You broke my heart by accident. What I need is your encouragement! Mom and Dad, I hope that one day we can sit face to face and talk about our feelings calmly. However, every time, you say that you won't do your homework right away. You don't know how many nights I hid in the corner and cried silently. Your expectations and requirements for me are like a boulder, which makes me breathless ... It is said that communication is a bridge between hearts, but why? Why is there a "generation gap" between us and our parents? Let's sit down and talk to our parents, tell them what we think, let them know what we think, let them know about us, let us go into their hearts and listen to their thoughts.

I believe we can make friends with our parents, and our parents can also change! Mom and Dad, please listen to my heart.

One day, I went out to play alone and suddenly found a frog catching insects. Suddenly, the frog put out its long tongue and aimed at the target. The bug was caught in the frog's mouth.

After watching this scene, I was surprised and funny, so I wanted to help the frog catch insects! I looked around and found some grasshoppers in the grass ahead. I crept up to the grasshoppers and covered them with my hand. I ran away. Once again, I saw the grasshopper and covered it with my hand. Unexpectedly, the grasshopper was trampled to death by me. I thought: Being dead is the same as being alive! I threw the grasshopper in front of the frog and stole a look at it. Five minutes passed and ten minutes passed, but the frog just wouldn't eat the grasshopper I gave him. I was curious and ran home to ask my father.

Dad said, "Frogs have strange eyes. He is keen on seeing moving things, but he turns a blind eye to still things. Scientists got inspiration from frogs and invented "electronic frog eyes". With the help of "electronic frog eye", the airport commander can command the plane to land more accurately! " Through this discovery, I understand a truth, pay attention to learning everywhere, seemingly ordinary nature actually has many mysteries waiting for us to explore and discover! I am proud of my little discovery!
