However, the flower with the most blooms and the richest colors is the sunflower. As the saying goes: "Good flowers don't bloom often."

Sunflowers are also good flowers, including red, yellow, white, purple, crimson, orange... The petals of sunflowers are single-layered and shaped like plum blossoms. There are red and black filaments with yellow spots. The stems of sunflowers are long, thin, soft, and curved.

Its branches are very thin, the leaves are dense, and there are many flowers. Sunflowers bloom only when they see the sun. Every day when the sun rises slowly from the east, sunflowers rush to open their smiling faces.

When the breeze blows away, the sunflowers "shake their heads and shake their heads" as if they are reciting poetry, and they seem to nod to pedestrians. The flower buds of sunflowers are red and about the size of a soybean.

Different from other flower buds, they are short and round. The flower seeds of sunflowers are surrounded by several small leaves.

The flower seeds are as big as sesame seeds. When the small flower seeds are ripe, they are scattered in the arms of Grandpa Earth. After being moistened by the sun and rain, they will grow and bloom into more beautiful sunflowers in the second year. . The vitality of the sunflower is very strong. She sucks the nectar given to her by Grandma Lantian to her heart's content. She greedily absorbs the nutrients from Grandpa Earth.

Sunflowers thrive under the care of Grandpa Earth and Grandma Blue Sky, making the motherland more beautiful and adding to the beauty of nature. At night, the sunflowers are like children who have been playing all day, falling into a sweet dreamland tired but relieved.

Although sunflowers do not have the nobility of roses, the fragrance of chrysanthemums, the purity and elegance of magnolias, or the fragrance of plum blossoms, sunflowers have the spirit of selfless dedication. I love sunflowers.

After being put in the cage, he didn't eat or drink all day long, he couldn't sing any more, and he fell asleep every day.

His head was flying around in the cage, and sometimes he was banging his head against the cage like a crazy bison. However, one day, he suddenly heard the cry of a bird and ran out. Look, it turned out to be an old bird talking to the little bird! They would also hold the iron cage with their mouths from time to time... When Xiao Ming saw this, he immediately understood what the old bird meant. It turned out that the reason why the little bird stopped singing every day was because it was homesick, and no matter how delicious food was given to it, it would not work. , no matter how nice a house you give it.

Domestic cats can live in human resting places. What about feral cats? Wild cats generally live on the grassland, relying on the grass on the grassland to shade themselves. Cats are agile. In the wild, cats rely on their agility to catch birds flying in the grass. In fact, domestic cats are also trained by wild cats.

Many people say that cats are afraid of water and dare not go into the water. In fact, cats dare to go into the water and swim.

But that’s just a cat living in the wild. Cats are very clean little animals. No matter where they go, their bodies are always clean and slippery.

The smallest cat in the world is only as big as a piano key, only two centimeters. The fattest cat in the world weighs fifteen kilograms.

The feathers around the eyes are arranged in a round face shape, and with the pointed ears on both sides of the head, it looks very like a cat. Its eyes are like copper bells, its mouth is like a sickle, and its claws are like sharp iron The hook looks very majestic. Since ancient times, the owl has always been regarded as an unlucky animal, and it is even called a "mourning bird". This is a huge injustice.

In other words, one owl protects 1,000,000 kilograms of grain for humans in one summer, which is worth A year's ration for three people. The owl can accurately catch cunning mice in the dark night. Because its retina is mainly composed of cylindrical cells, the sensitivity at night is a hundred times greater than that of human eyes. The owl can It detects high-frequency sound waves that oscillate more than 8,500 times per second. The sound waves generated when wild mice move happen to be in this high-frequency range, so no mice can escape the hunting of owls. Now, you should know why I like owls, right? I hope you will fall in love with the owl after reading this article, protect it, cherish it, and do not catch or eat it illegally, because it is the pride and resource of our motherland.

The baboon is a large monkey, as smart as a chimpanzee. It After eating wild fruits, his lips will be stained with juice, so he picks up a stone as a "napkin" and wipes his mouth and nose repeatedly. In the Chicago Zoo in the United States, a large baboon tried to eat the juice from the food plate outside the cage. To get food, ask a small baboon to fetch a hook-shaped tool, and then hook the food plate close to eat together. Farmers in southwest Africa use baboons to guard their flocks, with good results.

According to the season, it can be divided into spring radish and autumn radish; according to the size of the root, it can be divided into three types: large, medium and small; according to the color of the radish, it can be divided into white radish, green radish and red radish.

Although many households in rural areas grow radish, many people do not fully understand its wide range of uses. Radish contains many nutrients.

It contains large amounts of glucose, fructose, sucrose, various vitamins and minerals. The vitamin C content is eight to nine times more than that of pears and apples.

If radish is used instead of fruit, its vitamin content will only be even worse. The pungent flavor of radish is also a useful substance.

Together with the digestive enzymes in radish, it helps the gastrointestinal tract digest food, especially fat. After people eat greasy food, eating some radish will relieve the greasiness.

If people overeat during meals, they can also eat some radishes. Before liberation, there was a man in our village who liked to bet with others.

"Sure enough, less than an hour after he went out after dinner, he swaggered into the door of the house again. People were vying to ask him what "miracle medicine" he had taken to avoid being strangled to death. Under people's questioning, he had no choice but to Said: "After I went out, I picked two radishes from the field and ate them, so I can stand here well now." ”

Why can radish help digestion? Because radish contains a lot of mustard oil, fiber and a variety of digestive enzymes, these substances can promote intestinal peristalsis and help digestion.
