There is a lot of water in my hometown, and water footprints can be found everywhere. The water in my hometown is very clear. According to my mother, when she was a child, I could see fish swimming freely and happily in the water. These little fish are dancing in the water. It's fun to turn around. At that time, water was used for many purposes, and all domestic water was this river. In summer, go swimming in cold water, not to mention how happy you are; If you are thirsty, just run to the river and gently lift it with your hand to taste it, and you will taste sweet water. I don't know when it started, but my mother said that the water in my hometown has changed, which is what I see now. The muddy and dark river is full of rubbish, and it becomes a smelly river in summer. Fish also hate this environment and have moved away. We can't bathe and wash clothes in the river anymore. Why is this? This is because with the development of science, many factories secretly discharge a lot of sewage, and people also pour all kinds of domestic garbage into rivers, which destroys the water environment. We should protect the environment, start from ourselves and give us a clear river!

It seems that they will fall if they are not careful. After visiting such a beautiful Feng Guilin water, although I can't say a thousand words, I can always say these words clearly, that is, "Guilin, you are so beautiful, I love you!" "
The water in my hometown changes the most, and it will become more beautiful with the changes of the four seasons.
In spring, there are small fish in the river in my hometown, and the fish swim freely. Blue ducks and white geese swim in the river, catching small fish, and they are "the prophet of warming ducks on the riverside".
There are also small animals playing by the river on the mountain. When they are thirsty, they go to the river to drink water. Others went to the river in my hometown to see small fish, and they swam around like colorful stones.

4. Write a short composition about water, 120 words. Life was born when the first breath of vitality was injected into the chaotic primitive ocean.
Later, water, with its broad mind, pure and transparent quality and unique charm of heavy oil tanks, touched the brushstrokes of many literati in past dynasties and wrote many tragic stories.
Boda
The autumn wind is bleak, the waves are rough, and the Yangtze River is rolling eastward, which can't wash away the inner depression and helplessness. "Born in, is it clear?" The grass boat borrowed arrows, the east wind borrowed laws, and the raging fire in Battle of Red Cliffs burned a lot of pride and arrogance in Zhou Gongjin. Vast rivers, winding rivers, rivers, how can they be like this endless intestine?
Without the vastness of water, you don't have the tolerance of all rivers. You are jealous of virtuous people and can't tolerate Yu Liang being born in the world. Anger and shame will eventually kill you. Maybe in heaven, there will be a clear spring to wash away your jealous heart. I wonder if you will feel deja vu when you look at the water on the blue planet.
Water teaches tolerance, just like the endless sea, selfless, broad and broad.
spring scenery
"The mountains are high and the water is long, and the soup is flowing." The moment of being honest with each other and the harmony between music and theory next to the flying sword are fixed as eternal stories. A bosom friend is hard to find. Boya played the piano when he was a child, and piano wrestling was also a child. This feeling is not touching. "The mountains are high and the water is long, and the soup is flowing." The moment of being honest with each other and the harmony between music and theory next to the flying sword are fixed as eternal stories. A bosom friend is hard to find. Boya played the piano when he was a child, and piano wrestling was also a child. This feeling is not touching.
Nowadays, it is difficult to find bosom friends. Just because there is too little purity. Without the purity of water and a transparent and open mind, there is no sincerity in the world. Why not accept its hypocrisy and show sincerity?
Looking at this crystal clear water, how can our heart, which has been buried by secular dust for too long, not have the sincere impulse to see the sun and breathe? Embrace innocence, embrace sincerity, achieve the lofty friendship like Marx and Engels, be a sworn friend, never leave, never forget that year, as long as you know each other and hold hands, the meaning is the same.
Water teaches sincerity, just like a drop of rain on the tip of a leaf, transparent and pure, reflecting the light of the sun.

"The softness of the world is nothing more than water." Dropping water day and night gives water infinite power. Because of the small loss, because of the small loss, he secretly accumulated strength until the stone of ten thousand years was ground a little, which made a feat of piercing the stone in the amazing attention of the world.
Knowing perseverance, Zhu Kezhen observed and recorded the weather for decades, and finally became a world-famous meteorologist and learned perseverance.
Beethoven played the magnificent symphony of destiny with his heart in the silent world. With the strength of combining rigidity with softness, the world will have more persistence and persistence.
Water teaches people to persevere, just like dripping water through a stone, falling, falling, and finally having the joy of success.
Water, this is water. Water touched me with its broadness, purity and strength, and I want to write my life with broadness, purity and strength. I dare not expect a glorious life, but hope-no regrets in this life.
5. Look at the pictures and write words in the second grade. How to save water is a simple example:
On Sunday, when Qingqing, Dongdong and Heping were playing in the park, they saw that the water pipe with the words "Save Water" on the corner was not turned off and the water was rushing. What a pity! How precious water is! Now the land in southwest China is dry and people have no water to drink. The water shortage is very serious! We should cherish every drop of water, form the good habit of turning off water at will and protect water resources. Thinking of this, three people immediately ran over and tightened the faucet. Then he went to play football happily.
More examples:
1,
One day, Xiaoming passed by the bathroom after school. Suddenly he heard the sound of "Hua" and turned to look. Someone forgot to turn off the water pipe. Xiao Ming hurried over to turn off his phone.
Xiao Ming thought: What should I do in the future? Xiaoming suddenly came up with a good idea. Xiao Ming took a pen and wrote four big characters "Save water" on the paper. Xiao Ming stuck "four big characters" on the top of the water pipe, which was very eye-catching.
Xiao Ming thought: Everyone should save water in the future!
2,
As soon as the kitten got home, she found a small river in front of her house, and the river was swift. It wondered strangely, where did this river come from? Is there a flood in our house? The kitten hurried to the kitchen and looked, "Oh, something happened. It turns out that I forgot to turn off the tap when I was washing dishes at noon! The kitten jumped up and tightened the tap.
Looking at the water all over the ground, the kitten regretted it very much: I was careless and wasted so much water! You must be careful what you do in the future!

The above examples can be used for reference, but you still have to write them yourself to make progress.
6. The composition (written by myself) about 200 words about caring for rivers in the second grade. I used to be a happy little fish. In the past, this river was very clear, where children could play games, catch small fish and shrimp, and adults could chat by the river.
One day, I don't know who discharged the sewage into the river, so I couldn't laugh with the children. I can't swim happily with children, nor can I live easily in the river.
Therefore, we should do this:
1. You can't throw garbage into the river, you must throw it into the trash can.
2. Change the trash can on time.
It is best not to drive a car, ride a bike or take a bus when going out.
Don't discharge the sewage into the river.
I believe that as long as we follow the above points, the river will become as clear as before.
7. The water in my hometown is not a compliment to my hometown. There are many beautiful scenery in my hometown, such as the towering Mount Heng, the beautiful underground Dragon Palace, the crystal clear Dongting Lake and the Great Wall in the south. These beautiful scenery are really beautiful, which makes tourists linger. Speaking of which, everyone should know where my hometown is! Yes, my hometown is in Hunan, which has been one of the tourist attractions since ancient times. But what I like best is the stream in my hometown.
I remember when I was a child, whenever I went back from vacation, I always went to play in the stream in front of my grandmother's house. This stream is very clear, clear enough to see the sand at the bottom of the river. Not far from the stream, there are several towering mountains. Under the reflection of the mountains, the stream is so green, like a piece of jade. The most beautiful time is morning. In the morning, the sun rises quietly, scattering warm sunshine on the earth. The sun shines on the surface of the stream. The stream is as red as a girl's rouge, which is really poetic. The stream gradually merged with the red light, and the clear and transparent water reflected the colorful clouds in the sky, showing an intoxicating picture. The clear stream is beautiful against the blue sky. Like a quiet girl, the stream flows quietly every day, accompanied by continuous mountains and kind and simple people, forming a beautiful picture.
How can such a beautiful hometown and such a charming stream not make people fondle it? These beautiful scenery can only be felt and experienced quietly with your heart!
Ah! My beautiful hometown, I love you! Ah! Charming brook, I love you more!

9. My hometown is Nagong Village, Yazhen Town, Longlin County, Baise City. Surrounded by mountains, it is a typical dashi mountain area. Although there are no magnificent tall buildings around, there are no amazing places of interest. But our beautiful scenery here will definitely make you linger.
In spring, birds are singing and flowers are fragrant, and there is a vibrant atmosphere everywhere. At this time, the children who stayed at home ran out of the house, holding a long-cherished kite in their hands and running wildly in the fields. Kites in the sky are gently blown by the wind, and they dance. In the blink of an eye, many kites appeared in the blue sky. Kites are like the finishing touch, forming a beautiful scenery with the sky. In February, farmers' uncles carried hoes and planted seeds of hope in the farmland.
Summer is just a good season for fishermen's uncles to fish. Sometimes, a pile of fish in the river is black and spectacular. About June, it's time to harvest millet. Farmers' uncles went to the fields with sharp sickles to harvest millet. Soon, several farmers' uncles finished harvesting millet in a farmland, and colorful vegetables and fruits were planted in the field, like the decorations of Aunt Earth.
In autumn, there are bumper harvests everywhere in the fields. Purple eggplant, chubby pumpkin, carrot in red skirt and black vine, they ran out of the ground in groups and breathed fresh air. The whole field is beautiful!
In winter, covered with snow, the snowflake turned into a white coat for aunt earth to attend the ceremony, which was very beautiful. The seedlings are covered with snowflakes, quietly waiting for the arrival of spring in the ground.
This is the beauty of my beautiful hometown, and it will definitely make you linger.
10. Changes of water in life: When water freezes, it will become fixed ice, and when heated, it will soon become water.
Popsicles and ice cream have ice when they are hot. Eat them quickly, or they will melt quickly.
Water will turn into gas when it is too hot.
The cloud we see is water vapor formed by water evaporating into the sky and cooling.
Water vapor gathers and falls to form rain.
As we all know, water has three states: solid, liquid and gas.
But there are more than three states of water, including supercritical fluid, supersolid, superfluid, fermion condensed state and plasma state.
Usually a colorless and odorless liquid.

Freezing point: 0℃
Temperature at maximum relative density: 3.982℃
Specific heat capacity: 4.186 kj/(kg℃) 0.1MPa15℃ Evaporation latent heat: 2257.2 kj/(kg) 0.1MPa100℃.
Density: The maximum density of water is 1* 103kg/m3 at 3.98℃, water is 0.99987* 103 kg/m3 at 0℃, and ice is 0.9 167 * 65443 at 0℃.
Critical temperature: 374.2℃
Thermal conductivity: at 20℃, the thermal conductivity of water is 0.006 J/s cm k,
The thermal conductivity of ice is 0.023 Joule/sec cm g,
When the density of snow is 0. 1* 103 kg/m3, the thermal conductivity of snow is 0.00029 j/s cm k.
Buoyancy classification: suspension, floating, sinking, floating and sinking.
