500-word composition in grade five

All the rivers on earth have dried up! Due to the increase of population on the earth, human consumption of water is also increasing. In addition, human beings have built many factories and cars, and discharged a lot of waste gas and dust into the air for a long time, which caused the warm winter on the earth and the destruction of the ozone layer, and the sea level kept falling ... Finally, one day, people ushered in this terrible day!

Once in the forest, there was no rain, and the trees dried up. The dried-up forest caused a fire and swallowed up the whole forest. Many small animals were burned to death, and those who survived quickly died of thirst. The originally dense and prosperous forest was desolate.

The grassland is bare, and there are countless holes in the ground, like broken glass plates. Some cracks still emit white smoke! There are corpses everywhere, antelopes, lions and zebras everywhere ... these hungry animals make the original vibrant grassland terrible.

In the city, the workshops stopped production and the streets became empty. People suffer from lack of water. How eager they are to get a glass of water!

Without water, animals, plants and human beings will become "Zhang Tianshi is trapped by ghosts-nothing can be done", and they can only wait silently for death to come to earth!

The earth finally rose from the dead and became a lonely ordinary planet in the universe. At the same time, what disappears is the infinite vitality that was once full of vitality!

Water is the source of life, and everything in the world is inseparable from water. Grass is moistened by water, making the earth green, and flowers are cared for by water, adding color to the world. Small fish are nourished by water and swim freely in the water ... The beautiful world is full of vitality because of water. What would the world be like if all the rivers in the world dried up?

If all the rivers dry up, we will have no drinking water. If you say, won't we drink water purified from seawater? But the cost is so high that many people have no money to buy it. Even if you buy water, your stomach may not be able to stand it. Besides, if there were no rivers, where would the sea come from? Although the sea is wide, it will run out one day and dry up one day!

If all the rivers dry up, there will be no green on the earth, let alone colorful flowers. When a tree dies, all its leaves fall off. Some trees will be uprooted as long as they hold the trunk with both hands. The grass is dead, and even the hay is gone in some places; I can't find the shadow of small flowers, nor can I see chrysanthemums, plum blossoms, lotus flowers and peach blossoms. This land has become a desert.

If all the rivers dry up, animals will flee everywhere. What a cruel reality it is to be able to chew, eat and even fight for a grass or a leaf. Because there is not a drop of water, the animals are very thirsty. Perhaps, before they die, they fantasize about drinking a full stomach of water.

If all the small rivers dry up, there will be only a few bouncing fish and countless fish and shrimp bodies left in the swift, clear and flowing river. The remaining fish breathed painfully and struggled for the last time.

If all the rivers dry up, we will not worry about eating, wearing and drinking, and the overlord of the earth will face extinction.

……

If all the rivers dry up, the world will be a dead world, a desolate world and a dead ocean. If all rivers dry up, the last drop of water will be human tears! Therefore, we should start from small things, from now on, protect and save water, so that these things will never come true!

6 14 I'm hungry for the Spring Festival. My grandfather and I have a New Year's Eve dinner and talk about our childhood. Grandpa said, "When I was a child, I was not as rich as your children now. Our happiest game in the past was catching birds, especially in snowy days. At that time, we were very naughty and didn't know how to protect those innocent birds. Some friends and I found a long nylon rope, tied it to a small stick and supported it with a small stick. Sprinkle some rice and wheat on the sieve, then grab the other end of the nylon rope and hide in the distance and stare intently. In a short time, several sparrows who were already hungry slowly approached the trap. A bold one jumped on the food first, and then several sparrows entered the trap one after another, just as they were eating crazily. We pulled the rope so hard that the sparrows became turtles in a jar.

Grandpa said, "To catch cicadas in summer, take a long bamboo pole and tie a plastic bag with lead wire at one end to make a net bag. When you hear cicadas chirping in the tree, you aim at them gently, put them in your pocket, then quickly put away the bamboo pole and catch cicadas with your hands. If it goes well, we can catch 20 cicadas in an hour. However, we didn't have enough food at that time. You can't wear cotton trousers directly in winter. The only things that can be played are homemade toys (origami planes, origami bags, slingshots). " As for you, you have a good meal, with chicken, duck and fish, and you can eat all kinds of vegetables in winter. You can eat almost anything you want, so should you be picky about food? There are also toys, such as cars, planes, submachine guns, scooters, roller skates and many other things that can be played. "Hearing this, I feel guilty. However, hearing this, I really want to go back to my grandfather's childhood and play all kinds of interesting games with them.
