Today, I found an ant hole, just under the corner next to my grandparents' house.

I caught an ant, which is made up of three small sesame seeds. The head and belly are black, like two bulging sesame seeds, and the middle is yellowish brown, like a shriveled sesame seed.

The ant's body is about 0.5 cm long, and it is as bright as a layer of paint.

Ants have two tentacles on their heads, which often shake gently. The ant's mouth is like a little tiger pliers, which opens and closes one by one.

Ant's legs are thin and long, and there are six in one. Its legs are as brown as its body, so it runs fast because it is long.

I put a small piece of meat next to the ant hole, and an ant found it. It touched the meat and went back. After a while, it came to touch the meat and went back, and so on several times. At this time, three ants came again, and they also came to eat meat. One of them went back to the cave. Soon, several ants lined up from the hole and went straight to the meat. Then there are more and more ants.

An hour later, I came back to observe and found that the ants had transported the meat to the door of the cave, and the meat was covered with ants.

I spilled water on the ant hole. There used to be a pile of fine soil in the cave, but now it is wet and scattered. Then I saw many ants coming out. They kept pushing the soil out of the hole, and soon the hole was opened, and ants could go in and out at will. Through this observation, I think ants are United, hardworking and fearless animals.

I am a small observer.

At noon today, my grandmother and I were walking in the street and saw several sanitation workers sweeping the floor by the roadside. Some people risk their lives to pick up garbage on the road, and some sanitation workers are old. Although they have clips in their hands, some things can't even be clipped, and they have to bend down to pick them up, but most old people can't even straighten up, let alone bend down. I feel backache when I look at it. I went over to them and asked them, "Grandpa and Grandma, can you eat like this?" Is it hard? One of the grandfathers said, "For your clean city and your comfortable life, no matter how tired and hard we are, we will be happy." "He also said," I haven't returned to my hometown to keep the road clean for the holidays for three years, but I don't feel lonely at all, because you have long regarded us as one of our own. "This year I was rated as advanced by the Institute and got a bonus. I am so happy! " Looking at his smiling face reminds me of our hard-won title of "civilized city". Without the hard work and selfless dedication of thousands of grandparents in Qian Qian, it would not be so easy for Changzhou to be rated as a "civilized city", so I must respect them and talk about civilization everywhere in the future!

Today, the teacher brought some seeds of boat-fruited Sterculia for us to observe! As soon as I saw it, I couldn't help thinking: Can you still be called "Boat-fruited Sterculia" at such a young age? I think it can only be called Bo Hai.

So small, it's not what I expected at all.

Boat-fruited Sterculia looks like dried red dates. It feels wrinkled and uneven. I sniffed with my nose and smelled a faint smell of traditional Chinese medicine. I bit its shell with my teeth again,

Because its shell is not very hard, it cracks when I bite it! Boat-fruited Sterculia is almond-like, which tastes bitter in your mouth.

Then, the teacher soaked it in the cup with hot water. At first, Boat-fruited Sterculia didn't change much. In a short time, the skin of boat-fruited Sterculia "cracked". After a while, the original clear water changed.

Slightly yellow, after a while, the color of the water gradually turned dark yellow. At the same time, I don't know where the shell of Boat-fruited Sterculia went, but we found it after carefully observing the skin of Boat-fruited Sterculia.

It turns out that the skin of boat-fruited Sterculia is next to it! Like a cloud.

Boat-fruited Sterculia is a Chinese herbal medicine. It will take effect soon! Boat-fruited Sterculia is no exception. Its functions are: clearing fire, clearing lung and relieving cough.

Today, I not only know a Chinese herbal medicine-boat-fruited Sterculia, but also know something about boat-fruited Sterculia! By observing the boat-fruited Sterculia, I feel that no matter what I do, as long as I observe with my heart, there will always be unexpected gains and happiness!

4. Ginkgo biloba autumn yellow

There are five ginkgo trees in front of our school, about the same thickness and height, probably older than my father. I like ginkgo trees very much, especially ginkgo trees in autumn and ginkgo leaves in autumn.

When autumn comes, the green ginkgo leaves begin to turn yellow, especially in the cold dew season of the first frost, the ginkgo leaves gradually turn from green to yellow, and then from yellow to gold. At this time, Ginkgo biloba leaves decorate the ginkgo tree golden, noble and particularly beautiful. Autumn wind came, and ginkgo leaves began to fall, from few to many, about a month. Golden ginkgo leaves are floating in the wind, like handfuls of beautiful small fans, fanning away the heat in summer, the coolness in autumn and the cold in winter. Ginkgo biloba and ginkgo biloba are a family, just like a mother and a child. Without the permission of the big tree, the leaves will not fall by themselves. I think the falling ginkgo leaves should be alive. This year they left their mother in tears, and next year they will definitely return to their mother's arms in another way with a lovely smile.

Ginkgo biloba leaves also have high medicinal value. A medicine my grandmother takes is called Ginkgo biloba, which can improve cardiovascular and cerebrovascular circulation and prevent arteriosclerosis. My grandfather also wrapped a lot of ginkgo leaves and made a ginkgo leaf pillow.

Ginkgo biloba autumn yellow is a landscape, but the falling ginkgo leaves are sour and reluctant to go.

Praise the grassland

Grass is ordinary, but it is selfless dedication; It doesn't have a beautiful appearance, but it can purify the air ... grass is always ignored, but it never complains. Therefore, I like grass.

What lovely grass! You can step on it, but you never complain On the contrary, it brings many benefits to people-beautifying the environment, purifying the air ... it absorbs carbon dioxide and releases oxygen at night; Its vitality is very strong, and "the wildfire is not extinguished, and the spring breeze is high" is enough to make people respect it; It grows short on the ground, never shows off its benefits and doesn't ask people for it. It is small, but its green color makes people like it ... the grass has no beautiful voice, but it has been dedicated to people. It is selfless, it is simple, but its spirit is touching!

Whenever I want to draft the beautiful quality, I can't help but think of those people who are unknown and selfless. Just like the police uncle on the road, in the snowy and cold winter, they don't hesitate to observe in the ice and snow to prevent traffic accidents ... how grassy they are! For doctors, life is extremely precious. So they often stay up late to save patients, and their eyes are full of blood ... how much contribution they have made to people! And those unknown cleaners, you can already see their busy figure at dawn, but they haven't come home at night 10 ... shouldn't we learn from them?

I like grass, and I prefer grass that serves human beings but never asks for it. Because there are hundreds of millions of people in their hearts, their selfless dedication is touching. Their simple faces and beautiful qualities make people admire them very much.
