Body:

What is life? Some people say that life is a time that never stops, a beating heart, an endless war, and their own ideas. But there is more to life than that, because everything in the world has life, even if it is an animal, a tree, or a small grass.

Life is only once, and life is fragile, but at the same time tenacious.

Leaving the grass on the plain, one year old and one withered. Wildfires burn inexhaustibly, and spring breezes blow and regenerate. "Yes, the vitality of the grass is so tenacious, but how inconspicuous it is!

You don't see, the cold of the year, where to ask for fragrant grass. I don't see it, Song Qiao, Qingqing Fu Jiao", that is the famous poet Li Fangying of the Tang Dynasty praising the strong vitality of Cangsong.

They always grow in the toughest places, such as in the crevices of the rocks, but if you look closer, you'll always find some "little guys" under their roots. Ah, it was a weed, it was an inconspicuous weed, a weed that no one would pay attention to, an obscure weed!

People will not be overjoyed to find a weed in a crevice of a rock, but will become accustomed to it. Because they are everywhere, on the beach, in the cracks of the rocks, on the rooftops, and even in the crevices of the roadside! They are not afraid of being bitten by animals, crushed by stones, burned by fire, or even cars running over their heads!

It never cares about being discovered and not being discovered.

It doesn't like to show off, unlike the proud peony; It doesn't seek to be tall, unlike the strong pine ......However, it only chooses to be a small grass, an obscure grass. But that's the beauty of it!

Have you ever seen a small grass grow under rubble and rocks? In order to yearn for the sunshine and achieve its meaning of life, no matter how heavy the stones on it are and how narrow the distance between the stones is, it must twist and turn, but it will be tenacious and unyielding to the ground.

Its roots dig into the soil, and its buds push into the ground, which is an irresistible force! The rocks that stop it will be moved, overturned, and even split!

Xiaocao has such a strong vitality, it is so tenacious, not afraid of twists and turns! He yearns for life and sunshine and has great goals, yes! Powerful beings all have a purpose, and they all have a great purpose!

Let us learn from Xiaocao together, no matter how difficult and arduous the road ahead is, we must strive for our goals, not afraid of setbacks, and advance in the face of difficulties!

Example: Cactus.

On the windowsill of my house is a pot of turquoise cactus, which was given to me by the old man who sold flowers when my parents accompanied me to buy Yunzhu last year.

The cactus is the result of the cactus, and it has many different colors, all of which are genetically transformed, but I still like the original body of the cactus - the green body, the yellow arms.

Cacti grow in sandy soil, unlike other plants that grow on my way. The sand is very dry, so why does it survive? It's spirit!

It is a spirit of unremitting self-improvement and tenacious struggle! In the desert, as long as it rains a little, then the cactus ball will not hesitate to seize the opportunity, work hard to grow, burst out of amazing vitality and motivation, it is by this spirit that it can survive!

However, now take out pots of cacti and cacti to buy them, and water them, fertilize them, and bask in the sun on time, because they are strong by nature, they are lazy and lazy, and completely rely on other people's parasites!

Let's bring plants back to nature! Heroes who grow up in greenhouses have no resolute character, only heroes who have experienced hardships and setbacks are real heroes!

The expository text describing the plant is as follows:

There are a few begonia trees near my house. Spring is coming, the flowers are blooming, begonias are no exception, they have many pink flowers on the trees, delicate and colorful, very cute, I put my nose up to smell it, and there is a refreshing fragrance of flowers.

However, one begonia tree was "sick". The other trees are vibrant, lush, and blooming very luxuriantly, but this one has only a few flowers, and the flowers are not luxuriant. What's going on here?

I decided to take a good look at this "sick" little tree.

I looked at the tree from head to toe, and there was nothing out of the ordinary. I compared this tree to the other trees - oh, it turns out that this "sick" begonia tree is surrounded by bushes of dwarf bushes, while the other begonia trees are not surrounded by dwarf shrubs.

I found a flaw, but a big question mark arose in my mind: why did the trees surrounded by low bushes not grow? Is it because the bushes of dwarf bushes have affected the begonia trees, well, it is possible.

I looked at the bushes and there was nothing unusual about them. I scratched my head and thought about it for a long time, but I still hadn't figured it out. Looks like I'm going to have to ask for a computer.

As soon as I got home, I turned on my computer and looked for answers to my questions. It turns out that it is dwarf shrub trees and begonia trees that rob nutrients; The nutrients of the plant are the organic salts in the soil. Dwarf shrubs are planted around the begonia trees, "robbing" the nutrients needed by the begonia trees, and the begonia trees lack nutrients and of course do not grow luxuriantly.

On the contrary, the begonia tree, which is not surrounded by dwarf bushes, has no one to compete with it for nutrients, and it does not lack nutrients, so it grows luxuriantly. Oh, I see.

Grape. There is a vine in front of my house that grows on the wall of the backyard and loves to climb. Its trunk is brown Qingming, which is the kind of dark brown that at first glance, it is reminiscent of an old grandfather.

Its foliage is very lush. From a distance, it looks like a green cloud. He has many hands, always touching this and that, and in summer I like to sit under the vines in the shade, sit on the little maza, and listen to the cicadas.

In September, you can also pick some and invite friends to taste them.

Isn't that fun? It's just that the branch is a little thin, and it's not good if it is torn off by a friend who comes and goes, and the whole cloud begins to shake. It's inseparable.

Therefore, the grandmother who lives next door always says that planting grapes in front of the door can hope that her children will come back to reunite.

Grapes are also divided into many kinds, oval-shaped beauty fingers, round giant peaks, sour and sweet, unique flavor, very refreshing to eat in summer. Grapes contain a lot of vitamin C, which can boost the vitamins you need and are a healthy food. If you don't want to eat freshly picked grapes, you can also choose to make raisins or make wine.

When you make good wine, the whole village will smell the fragrance of grapes, and the aroma of grapes is rich and intoxicating. Flavor.

Sweet and sour with a wine aroma, you will be intoxicated after a few sips. Good wine is not only delicious, but also very good for the human body, for people who often stay up late, grapes can soothe physical and mental fatigue, slow down aging, and can also strengthen the heart.

Grapes have many other functions, grapes also have the wonderful effect of beautifying the skin and cleaning the face, so girls should eat more. The vine in front of the door has gone through five springs, autumns, winters and summers, but in summer, it will still flourish.
