To produce the same food, we use twice as much water as the United States.

According to Zhang Chunyuan, Vice Minister of the Ministry of Water Resources, agricultural water accounts for the bulk of my country’s water consumption, accounting for about 72% of the total water consumption, but the water that is actually effectively used accounts for about 1/3 of the total agricultural irrigation water. . Cherish the water around you Shuangliu Experimental Primary School Luo? There are endless emerald green water, clear water, cool water and sweet water... Water is the most precious and hard-to-get gift given to us by nature.

Drops of water, trickles, rolling waves, and surging rivers, we can never do without water, but on that crisp autumn day yesterday, on the bank of the already turbid Baihe River, I saw something that made me extremely angry and furious - someone threw garbage into the river! Someone actually threw garbage into the river! At that time, my heart was suddenly burned with raging anger, and my hands were itchy. I wanted to go forward and beat the person who threw the garbage, to avenge the fish that died due to the pollution of dirty water; for the fish The anglers who died one by one without being able to catch fish vented their anger; they scolded the people in drought-stricken areas who could not drink water; they felt sorry for China, a country with severe drought and water shortage. But in the end, when I saw the person who littered the river consciously picked up the garbage he had thrown away through evil hands from the river under the guidance of others, the anger in my heart was extinguished a lot by the fire extinguisher.

Today, I went home and observed boiling water composition. My lips were split with thirst. But it happened that there was no water to drink at home. I was so anxious that I boiled some water myself. I waited for a while and the water boiled. I poured the water into the kettle and just finished pouring all the water. Suddenly a few small water drops jumped to the edge of the kettle. First there were one or two, then dozens, and slowly more and more, like little girls wearing beautiful white wedding dresses, crystal clear and very beautiful.

Part 1: Continuous Observation Diary of Daffodils Saturday, October 16, 2014 Weather: Sunny Today, the sky is clear, Teacher Zhou gave us a Each classmate was given two daffodil bulbs, and I was very happy.

Narcissus is called the Lingbo Fairy and is one of the top ten famous flowers in my country. Every New Year, people like to make daffodils and decorate them as new year flowers.

Its bulb looks big, like a white garlic, wearing a gray-brown dress. I didn't notice it at first, but then I took a closer look and found a small milky white bud on the head of the bulb.

Daffodils can be cultivated in soil or water. You can also cut off the outside, so that they will bloom earlier. However, do not cut off the center of the flower, otherwise it will be useless. My father and I first brought a basin of water, then a knife, and peeled off the gray-brown skin on the outside of the narcissus, then cut off half of the narcissus bulb, and finally soaked it in the water.

After a while, I found that the water in which the daffodils were grown gradually became sticky and turned brown. My father said that only cut daffodils have mucus, and it would be fine if the water was changed a few times. In order to protect the cut area of ??the daffodils, Dad also put some cotton balls on it.

Thursday, October 22, 2014 Weather: Sunny After a week, the daffodil bulbs I raised slowly grew up and sprouted many roots like bean sprouts. The roots used to be just a little bit long, but now they have become much longer, about 5-6 centimeters. When turned upside down, they still look like hanging hairs. It’s so interesting! The daffodil bulbs not only grow roots, but also sprout small green shoots! The buds are green and about 2-3 cm high. I found that my daffodils grow faster than others because I cut off part of a bulb, so the buds grow higher than others.

I hope the daffodils will grow up quickly and bloom into beautiful flowers. Weather on Tuesday, December 1, 2014: Sunny. Many new buds sprouted from the daffodils I raised, all green and shiny. It seemed like they were saying to me: "I want to absorb as many nutrients as possible."

< p> There are also many very long buds. I measured them with a ruler and they were about 21 centimeters! I touched the top of the bud with my hand and felt something hard. I didn't know what it was. The peeled daffodil bulb has grown almost as high as the unpeeled one. Originally, the peeled daffodil bulb grew taller, maybe because it didn't absorb enough water! Wednesday, December 2, 2014 Weather: Sunny Today is a sunny day. Teacher Zhou asked us to go to the flower bed next to the school garden to observe the daffodils.

I found that the daffodils I planted have undergone tremendous changes in this month. The daffodil leaves have grown much taller.

Originally, it had just sprouted a head, less than 2 centimeters tall. Now it has grown very tall, from the original 2 centimeters to 20 centimeters, revealing a tall and straight figure. The leaves are bright green in color, and there are many new shoots sprouting next to them.

The new shoots look short and very cute against the long leaves. The branches of the new buds are round, with a hard-to-the-touch bud at the top. Beautiful flowers are gestating in it. When the time comes, white flowers will bloom at the top.

My flowers and leaves are not the tallest, the tallest ones are more than 30 centimeters long! It should be allowed to absorb more nutrients so that it can grow taller. I also noticed that my daffodil bulbs were getting smaller, this is because the nutrients inside were being released and they were getting smaller.

Some flower buds also cracked a hole, I think this indicates that they are about to bloom! The roots of my daffodils don't seem to be very long, they are still short, like bean sprouts. The one raised by Teacher Zhou is different. It is 10 centimeters long, dense and dense, and looks very strong.

I should learn from Teacher Zhou and try to make my flowers grow taller. I hope my daffodils will grow taller and bloom quickly, bringing everyone a beautiful enjoyment.

Sunday, February 7, 2015 Weather: Cloudy Oh, after 3 months of careful cultivation, my daffodils have bloomed, and the stamens are slightly trembling, exuding bursts of quiet fragrance, which is refreshing.

The slender leaves of the narcissus are delicate, moist, and green, as if they are the arrows of spring sent by the goddess of flowers.

Its six snow-white petals stretch out in all directions, and a circle of bright yellow petals in the middle stands playfully upright on the snow-white petals. Every day, as soon as I walked into the classroom, I saw countless daffodils blooming. The flowers were as delicate and beautiful as a little girl, white, lovely, and graceful.

The daffodils shine brightly in the sun and exude a fragrant fragrance, which makes us feel extremely comfortable. At the same time, the daffodils also make our classroom extraordinarily beautiful! Chapter 2: Observation Diary of Narcissus Before the Chinese New Year, my father bought a pot of narcissus from the flower and bird market. Daffodils are served in a red plastic bowl.

Its roots are like tender white garlic, but there are some short "beards" in the center. Those "beards" are yellowish in color, slightly darker at the top.

The bottom of the narcissus leaves are tender green. After a few days, the color of the leaves gradually becomes thicker and darker.

The feel is also smoother, the thickness is thicker, the top is semi-circular, and the color is lighter. After a while, I discovered that some thinner flower stalks were covered with blooming daffodils and flower bones clustered together.

The bottom of the narcissus petals is light green, similar in color to the leaves, and the stamens are yellow. Each flower has about 4 stamens, 3 pistils, and 1 stamen. At the outer bottom of the petals, there is something like an umbrella without a handle inserted upside down on the flower. After checking the information, I found out that it is the receptacle and the flower handle.

The petals of narcissus are very beautiful: white, tender, and very soft, as if they will fall off when touched. The flower bones are like small green beads clustered together, bulging and full.

And it exudes fragrance from time to time. It smells so good! Through this observation, I found that as long as the daffodils are given some clean water, they can grow vigorously. The daffodils are so vital! Chapter 3: Observing Narcissus This afternoon, my father bought me a small potted plant.

It turned out that there was a beautiful daffodil inside. Today I just have to complete the composition assigned by the teacher and write an observation diary.

I think it’s better to take a good look at this pot of daffodils and then complete this observation diary. The pot of narcissus that caught my eye was very elegant and delicate in appearance. When I smelled it with my nose, the fragrance was overflowing, which made people feel a little intoxicated.

The petals of narcissus are all upright, the center of the flower is yellow, the petals are white, and its root is tuber-shaped, like a large brown onion. 5. Please write an observation essay of 150 words

One day, I took a few grains of rice to lure ants out of their holes. After a while, the ants really came out. They were covered in black and looked like heroic fighters. Their appearance made them look particularly mysterious. A pair of tentacles were their communication tools, connecting them with their great spirit. It’s simply amazing! It smelled it, as if it didn't know what it was. When it repeatedly observed and confirmed that it was food, it went back to the hole and called more ants out. After the ant leader learned about it, he called out the army. Some of them took a bite and took it back to the hole first, while others moved it together. In less than 20 minutes, they all moved away the rice I gave me. I was stunned.

Ants are so powerful. It seems that we should also learn from ants

’s spirit! 6. A 150-word essay about waterways

During the Chinese New Year, I came to my grandma’s house. It's time to take advantage of this opportunity - go for more walks in the mountains. On this day, my sister happened to be there, so we agreed that they would go to the depths of the mountain to find out what was going on.

At 1 o'clock in the afternoon, we put on our coats, put on our travel shoes, and set off towards the mountains along the small alley. After walking a few steps, there was a vast open space in front of us. My sister and I happily embarked on the rugged mountain trail while humming a little tune. Time flies faster and faster, and before we know it, we have gone very far, and the road under our feet is getting smaller and smaller, leaving only countless weeds. The wind blew in waves, but the creek beside the road was still flowing. My sister and I suddenly came up with a unique idea - to take the "water route". The creek is not particularly deep. You should be able to return by stepping on the rocks. Without saying a word, we started.

Stepping on the stone road, we retreated from the path with a height difference of 2 meters to the creek. The large stones in front of us seemed to be specially designed for us. The gap was just right. We held hands and turned over every stone carefully and down-to-earth, fearing that we would step on water. The road ahead was smooth sailing. Then a big trouble fell from the sky. What was in front of us was a The steep slope is 90 degrees, with a difference of nearly 1 meter between the top and bottom. Coupled with the rushing water, the rocks are covered with moss. Looking back, I have walked a long way and it is too late to go back. Now we are in a dilemma, what should we do? My sister and I stared blankly at these silent stones without saying a word.

I tried my best to plan the walking route in my mind. Is it faster or safer to walk this stone first? A minute later, I jumped from the 1-meter-high pile of stones, stood on tiptoe behind a dry stone with only a corner exposed, subconsciously jumped to the left, and finally landed narrowly. I waved her over. Likewise, she "bout" me with ease.

We were so excited that we clapped our hands and splashed water to express our great celebration. The road ahead became easier and happier as we walked, and we kept moving forward with great strides. When we arrived at the deep pool, we saw a pool half a meter deep and 3 meters long in front of us. Knowing the past is impossible. I had no choice but to climb over the 2-meter-high rock with my sister. Hey, little case, we climbed over the rock wall easily and dexterously like two little monkeys. We are back to the familiar trail.

The wheat on the edge of the field smiles, and the flowers in the bush bloom. It was warm and cozy, filled with our bright smiles and sweet songs along the way.

Let’s take the “waterway” together! You can shrink it yourself 7. Observation Diary: Salt Water Floating Eggs 150 words

Today, after I finished my homework, I had nothing to do, so I did an experiment of eggs floating in water.

I first prepared some experimental equipment: a transparent glass cup, a spoon, raw eggs and a large jar of salt.

I first scooped half a large cup of water into the cup, and then put the eggs into the cup. I saw the egg sinking to the bottom of the cup all of a sudden. Then, I put salt into the cup and carefully stirred it to speed up the dissolution of the salt in the water. I stirred and stirred, and suddenly I found that the egg left the bottom of the cup, but after a while, the egg sank again. At this time, I put some salt into the cup. When I was about to put it away, my mother came back. When she saw the scene spread out on our table, she immediately started nagging: "You see you are making trouble again and don't do serious things." "No, I am doing an experiment, I am doing how to make the eggs float in the water." But when my mother heard what was going on, she quickly handed me a bag of fine salt and said, "Fine salt dissolves faster than coarse salt." So I added a few spoons of fine salt. Salt, mix it lightly, the eggs really float, and they even come to the surface. I shouted happily: "The experiment was successful, the experiment was successful!"

When I was dancing for joy, my mother asked me seriously and seriously: "Do you know the reason why eggs float? ?" My mother's question made most of my joy disappear. I was really speechless at the time and couldn't make any sense. But my mother "forgave" me and gave me time to look up information and find answers on my own. Later, I found the answer on the Internet: when the weight of an object is greater than the buoyancy of water, the object sinks; when the weight of the object is less than the buoyancy of water, the object floats. Water has specific gravity. When we add salt to water, we increase the specific gravity of the water. When it increases to a certain value, the specific gravity of water is equal to the weight of the egg, and the egg will be suspended in the water; if the specific gravity of water is greater than the weight of the egg, the egg will float to the surface. It turns out that my mother asked me to constantly add salt to the water in order to increase the specific gravity of the water, so the eggs floated to the surface.

By using your hands, doing experiments, using your brain, and looking up information, you can really learn skills and gain knowledge. How interesting! 8. Write a 100-word essay on the topic of water

The association of water In ancient times, when the first energetic breath was injected into the chaotic primitive ocean, life was born.

Later on, water, with its vast and broad mind, pure and transparent quality, and the special charm of a meat-heavy oil tank, moved the pens of many literati throughout the ages, and wrote many soul-stirring fierceness, evocative and tragic. Bo Da The autumn wind is bleak, the waves are rising, and the rolling water of the Yangtze River is passing eastward, unable to wash away the melancholy and helplessness in my heart.

"Since Yu is born, harmony is bright?" The straw boat borrowed arrows and the east wind, and the raging fire of the Battle of Chibi burned away a lot of Zhou Gongjin's pride and arrogance. How are the vast rivers and winding rivers like this ever-turning intestine? Without the broadness of water, you do not have the magnanimity to accept all rivers. You are jealous of the virtuous and capable, and cannot tolerate the birth of Yu Liang.

If you are angry and ashamed, you will eventually die. Maybe in heaven, there will be a clear spring to wash away your jealous heart. I wonder if you will feel the familiar and magnanimous relief when looking at the water on the blue planet.

Water teaches people tolerance, just like the endless sea, selfless, broad and broad. Pure "The towering mountains are shouting, and the soup is like flowing water."

This section of the Feijian treats each other with sincerity and the harmony of music and theory has been fixed as an eternal story. It's hard to find a close friend. Boya playing the qin is a child, and breaking the qin is also a child.

This affection is so touching. "The towering mountains are shouting, and the soup is like running water."

This moment of treating each other with sincerity and harmonious music and discussion beside the Feijian has become an eternal legend. It's hard to find a close friend. Boya playing the qin is a child, and breaking the qin is also a child.

This affection is so touching. Nowadays, it is no longer easy to find a soulmate who has worked hard and worked hard.

Just because people have too little purity. Without the purity of water and a transparent and open mind, there would be no sincerity in the world.

Why not accept the hypocrisy and show sincerity. Looking at this water as transparent as crystal, how can our hearts, which have been buried for too long in the dust of the world, not have the urge to see the sky and breathe sincerity.

Embrace innocence, embrace sincerity, achieve a noble friendship like Marx and Engels, and make a sworn friend who will never betray you or forget the years, as long as you know each other heart to heart, hold hands, and have the same intention. Water teaches people sincerity, just like the drops of rain and dew on the tips of leaves, which are transparent and pure, reflecting the rays of the sun.

Power “There is nothing softer in the world than water.

"The dripping that persists day and night gives water infinite power.

Being ignored because of its insignificance, it secretly accumulates strength because of its neglect, until it wears away the rock of ten thousand years little by little, and in the eyes of the world's astonished With the feat of walking through rocks, Zhu Kezhen learned about perseverance, observing and recording weather conditions for decades, and finally became a world-famous meteorologist. Knowing how to persevere, Beethoven played the symphony of destiny with his heart in the silent world. The majestic song, with the power of water's hardness and softness, makes the world more persistent and persistent.

Water teaches people to be persistent, just like water dripping through stone, falling, falling, and finally achieving success. Joy. Water, this is water. Water moves me with its broadness, purity and strength, and I will use its broadness, purity and strength to write my own life. I dare not expect to have a glorious life, I only hope - -No regrets in this life.

(Example 2) Let me tell you gently that I am a natural spirit, the darling of life, and my brothers and sisters are everywhere on this blue planet. I gently tell you my happiness, my sorrow, my secret.

I was wandering in the air, and Miss Chun asked me to send spring greetings, so the lightning flashed and the thunder came. The sound is rumbling, they are playing gongs to clear the way for me. I bring green clothes to the earth, colors to flowers, and joy to people. Look at our masterpieces: spring light, green grass, gurgling streams, clusters of flowers, colorful The butterflies are fluttering, the milk is dancing, and I am intoxicated. People take off their thick wrappings and play in my arms. Their smiles are charming and intoxicating.

Their praises make me happy: "Good. Rain knows the season, and spring will happen. "-Those who know me; "In the drizzle, fish come out, and in the breeze, swallows slant. ”

“The snow disappears outside the door, thousands of green mountains, flowers bloom by the river and it is sunny in February. —I got a little carried away with my picture album.

Yun'er became ill with worry, so I shared her worries and solved her problems. The land was thirsty and unbearable, so I gave her a cup of glycol. Cao'er was wronged and asked me to help her vent.

Dewdrops, that’s me. It was also her tears.

I am truly proud and happy for all of this. Sometimes, I am also very sad. I have come all the way to bring good news to people to defeat the officials and promote the ancient rules and regulations, but what greets me is a sky full of yellow sand; people do not cherish me and let me go with the dirt, which makes me even more sad. Scared, people kept telling me to eat dirty food, many of my brothers and sisters were changed beyond recognition, what was going on.

I was angry, lazy, and let the earth’s endless calls never come. I caught a cold and kept sneezing. I set off huge waves that reached the sky, breaking through people’s shackles. Unfettered, I set off houses. It flooded the grain fields and displaced people. You must know that this was not my original intention. If I had known this, why would people harm me in every possible way.

This is a lingering heartache in my heart, and I don’t know when it will heal. "When the great river goes eastward, its waves are swept away, and there are all the romantic figures of the ages."

My life is with history, let me polish the lens of history: Zu Di struck the middle stream and shouted for the restoration of the Central Plains. The flames of war in Chibi shone across the world, freezing the moment in history.

Zheng He traveled to the West to spread Chinese civilization. The People's Liberation Army crossed the Yangtze River and supported the backbone of New China.

The deceased is like me, never giving up day and night. It contains many changes in the land of China, and carries many "shaking the world, weeping ghosts and gods" deeds of the Chinese people.

This is the "sacred" secret in my heart. Let me tell you gently, I am very happy, but also sad.

I will be with you. (Example 3) Pin Shui occasionally flipped through a magazine and glanced at it casually: "Young people like to drink soda, which is sweet and varied, because young people don't know the taste of sorrow; young people like to drink coffee, which is bitter but sweet, fragrant and astringent, and has a very mature taste* ** Feeling; middle-aged people like to drink tea because it is fragrant and refreshing; old people like to drink boiled water because it is very light. ”

However, as a young person, I love this boiled water very much. . ——Written in front As clear as the wind.

As light as clouds. There is no reason to love drinking water.

Keep quiet alone. Enjoy a kind of peace and quiet.

Happiness ripples all over the world. I'm a very plain person.

Maybe this is why you love drinking water! A person, quietly, holding a glass of water, putting aside all distracting thoughts and all work. Maybe just for a "quiet".

But let your heart run wild and dream a "girl's dream" alone. And only. 9. Write an observation diary of 150 to 200 words

Six items in the observation diary Tuesday, March 14th. The weather is sunny. My family has seven lively koi carps.

Some are bright red, like little swimming suns; some are orange, like big oranges; and some are colorful, like chameleons. The shape of the small fish is streamlined, and the body length is between 6 and 12 centimeters.

I fed them fish food and hanajaki powder at the same time, and they seemed to prefer the hanajaki powder. When they breathe and eat, their mouths open and close like a trumpet, using suction to bring food into their mouths.

Wednesday, March 15th, the weather was cloudy. Today, my little koi is very lively and cute! When I was feeding, I found that they were all swinging their long white tail fins and fins on the abdomen, using their streamlined bodies and flexible tails to grab food at a speed of 50 to 60 cm/second. They are also very timid and will run around in the pond whenever there is any movement or sound.

Sometimes when two fish collide, they will swing their tails and hit each other's dorsal fin, as if to convey some message. When they swim, their tails swing between 98 and 180 degrees.

When they are very leisurely, they will "lie" in the corner of the fish pond to rest one by one, as if they are afraid of affecting their companions; when they are angry or scared, they will quickly "hide" among other fish, as if I'm afraid that others will see me. Thursday, March 16, the weather was sunny. Today, I had just finished feeding the fish food when I saw a spotted koi carp with a body width of 2 cm and a body length of 7 to 8 cm spit out a dark green object of 2 to 3 cm from its mouth.

After it finished spitting, it took a few breaths through its mouth and swam away. Several other fish also vomited such secretions one after another.

I think this white and dark green discharge could be food they don’t want to eat, or it could be stomach acid or bad bacteria in the water…. It seems that exploring nature is impossible without a wealth of knowledge! March 17, Friday, the weather turned cloudy from rain. Today, I put the fish food on a hook and stayed in the water for 5 minutes. A greedy little fish swam over.

Suddenly, I lifted the small hook, and the small fish swung its tail at an angle of 180 degrees, and its two belly fins shook back and forth vigorously. In the blink of an eye, it jumped 2 to 4 centimeters away from the water surface, and then fell into the water, stirring up circles of water vortices.

I searched for information: Carp (koi) can indeed jump, and can jump up to 1 meter. Carp in rivers and lakes often jump out of the water to play when the sun goes down.

There is also a folk legend of "carp jumping over the dragon's gate". March 18, Saturday, sunny weather. Today, I am going to change the water for the fish.

Before changing the water, the fish were all quiet, as if they were afraid of being discovered by someone, and "hided" below the water depth of 8 to 9 centimeters. Even if there is something delicious, just sit back and wait for it to sink by itself.

But the water has just been changed, and the fish are swaying their fins, chasing each other and playing. When feeding, everyone scrambles to eat.

Why is there such a big change? I personally think that although carp grew up in rivers and lakes, they are accustomed to living without changing water for a long time. But just like people like a clean home, fish also like clean water.

Clean water is not only "fresh air", but also does not fill the pond with excrement. Of course the fish like it! Sunday, March 19 The weather is sunny and cloudy. Fish love to play! Sometimes they pounce upward, sometimes they attack downward, and sometimes they chase each other in the water. However, these are all fish swimming forward, don't they "walk backwards"? Through observation, my answer is yes.

If you don’t believe it, look at my koi. When the little guy swims forward, its belly fins move backwards, and its body and tail move left and right, creating a vortex to push the fish forward.

So sometimes they can glide for a while using the current. When swimming backward, the belly fins paddle forward, generating a driving force just like we row a boat. In addition, the tail only swings to the right or left, and the fish naturally "reverses".

Two observations from the observation diary Wednesday, September 27, 2006 Weather: Sunny I had nothing to do today and saw a few snails. I started observing them.

The snail has straight antennae on its head. Its round eyes appear to be on straight antennae.

It carries a round and big "house" on its back, and the pattern rolled into a circle is printed on the snail's big "house". It has no legs that can jump around, so it can only crawl forward slowly.

I plan to have all the snails compete in a crawling race, only two tiles apart. The snail's sense of direction was okay at first.

But after a while, the snails began to move in different directions. One snail crawled to the left, and accidentally fell down the steps. I ran down quickly, worried about it: Will it die? When I got to the edge of the steps, I saw it clinging to the edge of the steps mischievously.

I slowly picked them up, put them in bottles, and put them into the small pool. It was getting late, so we went to bed together.

Saturday, January 7, 2006 Weather: Sunny Today, I came to observe the snail again, and the snail has gradually grown up. The last time I saw it it was as small as the fingernail of my middle finger, now it's as big as the fingernail of my thumb.

I organized them to have a crawling race. I want to see if they get faster as they grow up? I observed them for a long time and felt that their speed was still so slow.

I think the snail may be too hungry and unable to run fast. So I brought plenty of food - vegetable leaves and bread crumbs. The snail crawled slowly and ate very slowly. It took a long time for the food to decrease.

After finally waiting for them to be full, they slowly got up again. So I came to a conclusion: the snail has grown up, but its speed has not become faster.

Observing the things around you is so interesting and fun! If you don’t believe it, you can experience the fun of observation for yourself. Two Observation Diaries Wednesday, September 27, 2006 Weather: Sunny Today I had nothing to do and saw a few snails.

I started observing them. The snail has straight antennae on its head.

Its round eyes appear to be on straight antennae. It carries a round and big "house" on its back, and the pattern rolled into a circle is printed on the snail's big "house".

It has no legs that can jump around, so it can only crawl forward slowly. I'm going to have all the snails compete in a crawling race, only two tiles apart.

Snail’s sense of direction was okay at first. But after a while, the snails began to move in different directions. One snail crawled to the left, and accidentally fell down the steps.

I ran down quickly, worried about it: Will it die? When I got to the edge of the steps, I saw it clinging to the edge of the steps mischievously. I slowly picked them up and put them in.
