Introduce a composition

In study, work and life, many people have had the experience of writing and are familiar with it. By writing, we can gather scattered thoughts together. In order to make your writing easier and more convenient, the following is my 202 1 composition to introduce something for reference only, hoping to help you.

202 1 Introduction composition of a thing 1 In the fruit industry, there is a long "not very beautiful" fruit-kiwifruit. One end of kiwifruit is pointed, and the other end looks flat and hard. She has a thick dark khaki short Mao Mao, like a monkey. Although his appearance is not amazing, he has the title of "king of fruit"! Don't underestimate it.

Why is kiwifruit called "the king of fruits"? You should ask the right person. Fruit pulp contains a lot of vitamins. Every100g of fresh fruit actually contains 420mg of vitamin cl00, which is higher than that of sweet orange 1-7. Five times! Than. It is 5- 10 times higher than citrus and 20-30 times higher than apple. In addition, each kilogram of kiwifruit also contains 56 mg of calcium, 240 mg of potassium and 7 mg of sodium. Can't it be called the "king of fruits"?

Because kiwifruit has such high nutritional value, it has been applied to medical treatment in some cities. What do you mean it's not magical? Kiwi can stimulate appetite, even if many people who have no appetite may eat the "king of fruit", their stomachs will be wide open. Kiwifruit can not only help digestion, stimulate appetite, quench thirst, relieve fever and treat urinary calculi, but also increase intestinal peristalsis. It can also prevent cancer and treat diseases such as hypertension. Eating kiwi ornaments for three-month-old children can also promote intellectual development.

Just look at the gradual improvement of living standards. Rice and peaches have been included in most people's essential foods.

There are countless kinds of dinosaurs. In short, it can be divided into two categories: one is carnivorous dinosaurs, and the other is vegetarian dinosaurs, which are relatively docile.

I am a desert planet, full of sand dunes and rocks, and the atmospheric density is about 1% of the earth. There is no stable liquid water on me. I am dry and have a low fever. The average surface temperature is 55 degrees below zero.

202 1 Introduction of a thing Composition 8 Earthworms can be said to be the most common worms in the world. Dig in the cool and humid mud for a while and you will find a slender earthworm. Earthworms have different body colors due to different species and environments, and the most common one is the red earthworm.

Earthworms are annelids, and their bodies are made up of many different parts or small segments from beginning to end. Therefore, the life of earthworms can be prolonged. Because no matter how you cut the earthworm, it can grow, just like the gecko's tail. Earthworms can generally grow to 30cm long, and the longest is the giant earthworm, which is more than two meters long. Earthworms are invertebrates with very soft bodies. They wriggle in the waves.

Earthworms like dark and humid places. Live in a mud hole during the day and go out at night. Usually go out for food from 8 pm in summer and autumn to around 4 am the next day. The optimum temperature for earthworm reproduction is 22℃-26℃.

202 1 Introduction composition of a thing 9 Speaking of snakes, it seems that everyone will not be too strange. From the white snake god to the grass snake in the countryside, there are all twelve zodiac signs.

Most people think that snakes are just poisonous snakes, pythons, grass snakes and so on. Or they look like miniature dragons. They have scales all over their bodies, long tongues, delicate eyes and even look cute. Some people keep them as pets, but if possible, a boa constrictor can completely wrap around your upper body, turn your skin purple and then eat you alive. They are cold-blooded animals and don't have much feelings. The so-called peace with their owners is just in the crowd.

Snakes usually hibernate from March to June. Only China South China snakes don't hibernate. Snakes during hibernation are very fragile, so many snakes die unfortunately during hibernation.

Since the snake met this world, it has become a carnivorous cold-blooded killer. Their top speed can reach 20 kilometers per hour and they can attack from 2 meters away. Their stomachs are so big that pythons can easily swallow an adult.

There are many kinds of snakes, about 3000 kinds, many, many, but many are not in the majority. In the harsh environment and rising temperature, people also think that snakes are harmful. When they saw them, they took up arms and attacked them, which made the number of snakes drop sharply.

I like juicy grapes and red tomatoes ... but my favorite is golden orange.

An orange is shaped like a small lantern. The pedicels and umbilicus of oranges are a little concave inward, but the pedicels of some oranges are convex outward. Some orange skins are smooth, while others are rough. Rough skin is much sweeter than smooth skin! I peeled off the orange peel, and a smell came to my nose, which really made my mouth water! Orange petals in a circle, really like a dozen brothers and sisters get together and say an important thing! I opened the orange petals and saw that this curved and interesting Clementine musician really looked like a crescent moon! Tear off a thin, white and orange net. At this point, the pulp put on a transparent "coat". Take off my "coat" and see the golden, countless, raindrop-like pulp tightly together and take a bite, which really makes me memorable!

Oranges are not only delicious, but also orange peel can be made into dried tangerine peel, used as medicine, porridge and mutton stew to remove the fishy smell ... Oranges are treasures, so how can I not like them?

202 1 Introduction composition of a thing 1 1 White goose is a beautiful and arrogant little animal. Their whole bodies are white, their mouths are black, and the macules on both sides of the mouth base extend forward along the edge of the mouth under the nostrils. Two black bean-like eyes hung on my face.

White geese like to swim around in the water and occasionally flap their wings when they land. The great white goose lives in a big lake full of reeds.

They are 120- 160 cm long and 2 18-243 cm long. They often walk leisurely on the grass with measured steps, and when they are hungry, they stop to eat a few bites. That elegant long neck and beautiful voice are really as beautiful as dancing fairies.

Goose has the ability to look after the house. When a stranger enters the yard, the goose will hold its head high and shout loudly. Goose's gait is calm and grand, which looks like a clean corner in Beijing opera; The duck's pace is fast and awkward.

Goose is very arrogant. If someone comes fishing while playing in the water, it will definitely let out a cry and come to the shore to drive people away, as if the lake had been opened by itself.

This is a beautiful and arrogant little animal, white goose.

202 1 Introduction composition of a thing 12 "I'm all yellow, sweet and sour, and busy. The fruit only grows on trees, and everyone tastes it when squeezed into juice. " What kind of fruit is this riddle about? Have you guessed? Yes, it is mango.

Mango is a typical tropical fruit, belonging to Lacqueraceae. The varieties are Guiqimang, Qingpimang, Taijia 1, Guifeimang and so on. Mango has various shapes, some like pebbles, some like curved boats, some like ivory, and some like horns. ...

Its skin is very soft. If you peel it off gently, you will see golden yellow flesh with a big flat core in it. Take a bite of the pulp, and the sweet and sour taste will be directly secreted into your heart, with endless aftertaste. People can't help but give a thumbs up and say "delicious!"

Mango is not only delicious, but also nutritious! It contains vitamin B6, which is very important for the normal operation of the nervous system and brain. Mango can also improve people's memory; Mango contains a lot of strong oxidants, which helps to clean the poisons in the dirty. Dietary fiber and pectin in mango can help to lower the cholesterol level in serum.

Although mango has high nutritional value, people who are allergic to it can cause dermatitis. Compared with bananas and oranges, mango is not very convenient to eat, because its pulp is soft and contains a lot of fiber and water, so it is very easy to slip away when eating, just like a naughty loach, which can't be caught. Remember to wash your hands after eating.

Even so, I still love this fragrant mango.
