Introduce a description of something.

When it comes to composition, everyone is certainly familiar with it, especially expository writing, which occupies an important position. The purpose of expository writing is to give people knowledge: or to explain the state, nature and function of things, or to clarify things. So what problems should we pay attention to when writing this kind of composition? The following is a description of some things I collected. Welcome to share.

We are all familiar with the appearance of lips, but what is lip flower? It turns out that this is a strange flower, named after the outermost two bracts resemble sexy lips. This kind of plant is bright red in color and strange in shape, which makes people marvel at the ingenuity of nature.

Let's take a look at the appearance and distribution area of lip flowers first. Lipflower is a shrub or small tree, and its plant height is about 1 m. The red part shaped like lips is actually not a petal, but a bract of a flower. True flowers are in bracts, very small, yellow or white, and the flowering period is 65438+February to March of the following year. This exotic flower and grass is mainly found in broad-leaved forests, hillside forests or shrubs in tropical forests at an altitude of 350-1300m. It grows in the rainforests of some countries in Central America or South America, such as Colombia, Costa Rica, Panama and Ecuador.

Then, let's learn about the planting essentials of lip flowers. The feeding of lip flowers is more complicated. Feeding it needs to pay attention to the following points: first, the soil for planting lip flowers should be fertile. Second, pay attention to keep the soil moist, because the lip flower originally lives in the rainforest, so it is more suitable for an environment with sufficient water. Third, the planting environment of labiatae should be above 20 degrees Celsius as far as possible. Fourth, pay attention to pruning the branches of lip flowers. Fifth, we should illuminate the lip flower. Six, fertilization once a month. After hearing this, do you also want to try planting lip flowers?

Finally, let's take a look at the current situation of labiatae. Due to uncontrolled deforestation in some countries, the beautiful lip flower is on the verge of extinction. For the growth of exotic flowers and plants such as Labiatae, we must cherish trees and protect forest resources!

I have a special aquarium pet friend. Guess what this is? Fish? Turtle? Crab? Haha, neither, but a crayfish. My crayfish wears dark red armor, and often patrols everywhere with two scissors-like pliers, with two long tentacles swinging from side to side, just like a commanding general. Its conical head has two small round black eyes, like two black gems, and the most amazing thing is that it can stretch freely. It has eight thin legs and crawls with a body, as if dragging several carriages forward.

Crawfish are aggressive by nature. When I poked it with a stick, the prostrate crayfish immediately raised its upper body and waved two large pliers, as if to say: Who dares to mess with me? My pliers are not vegetarian. Look, I'll give you an invincible shrimp fist! It's so cute that you can run your teeth. When I put the stick into the water, it immediately lifted the stick with its big claws, sometimes horizontally, sometimes horizontally, sometimes high above my head, as if doing broadcast gymnastics, which really made people laugh.

In addition to grabbing things with big claws, crayfish also like to play the game of "prison break". It often erects itself, brandishes the big aojiang, and climbs with both hands and feet, as if eager for the wonderful world outside. But the smooth wall can't climb out. It tried again and again, failed again and again, and the box banged. It's really imposing without hitting the south wall and looking back.

Crayfish is an omnivore, eating everything, such as vegetables, fruits, rice, steamed bread and so on. Really a "good baby" who is not picky about food. Every day, I like to feed it and watch it eat. I put the washed leaves in the box, and I saw the crayfish immediately pouncing on the vegetables. First, it carefully picked up the leaves with its two claws, and then skillfully sent them to its mouth. The sharp mouth clattered at them, and while eating, it proudly shook its tentacles on its head, as if to say: delicious, delicious, delicious! . Soon, a large leaf of vegetables was wiped out. Sometimes, when I feed it watermelon, it will eat all the red pulp, leaving only the chewed melon skin. It seems that boiling jiaozi is also a teapot-know fairly well.

My red general has brought me countless happiness.

Introduce something to describe that the third folded-ear cat was born in Scotland and later crossed with the American shorthair cat.

Folding cats, mammals, carnivores. As the name implies, the ears are folded, and the two ears hang down beside the face. Round face, round and big eyes, many colors, gradient gold, gradient gray-black, tiger pattern, white chest, black and gray. Fat, medium build. The adult folding ear cat is about 6 kg, with short limbs and long tail, which is softer than the tiger's tail, shorter and more hairy than the lion's tail. The folded-ear cat looks like a beautiful S-shape from the side, with a body length of about 50 cm. The female cat with folded ears has a slightly pointed face, and the whole cat looks slightly like a tiger.

Just because a folded-ear cat likes to lie quietly doesn't mean it's not lively. Cats are desert animals. They prey on their prey and extract water from fresh meat without drinking water. However, when raising a family, we should pay attention not to feed dry cat food all the time, and supplement chicken, duck and fish appropriately. And feed insect repellent to the folded ear cat every month. Folding ears change their long hair in winter, and folding ears are used to sleeping in straw baskets in winter. Folding cats like to look out of the window and occasionally go out hunting. It likes to move things, so it's better to prepare a small animal to play with it. Folding cat is very docile, does not fight with other animals, and gets along well with its owner. The activity of folding ear cat can reach about three kilometers, and taking it out to play can be much bigger than dogs, chickens and ducks.

I suggest you keep a folding cat, which can be your companion.

The introduction of something Explanatory article 4 Looking at the fresh fruit in the fruit bowl, my mouth water suddenly flew to the sky in thousands of feet. Especially those red, moist, sweet and crisp apples always make my appetite big.

Apples look much better than those dried oranges beside them. Like a lovely princess. A thin coat with bright red and light blue is very suitable for wearing. Two small emerald leaves, like a bow, are firmly worn on the head, really like the little queen among many fruits in a fruit bowl.

Thirst, hunger, greed, fatigue ... Pick up an apple and take a bite, and the juice will immediately pop out of your mouth. The meat is crisp and tender without slag. Sweetness permeates the whole mouth and impacts your taste buds. When you slowly taste and swallow, your insides will be filled with that wonderful taste, urging you to take another bite quickly. Juicing is also a good choice.

Apples are not only delicious, but also have high nutritional value. This is one of the reasons why people like it. Its vitamin c content is extremely high. An apple a day supplements essential vitamins. "An apple a day keeps the doctor away." So eating apples often has many benefits.

It is said that the biggest and heaviest apple in the world is an apple in Kent, England, weighing 1. 67 kilograms. Although I haven't seen it with my own eyes, I know it must be much bigger than other apples. You know, the average weight of apples is only about 0. About 25 kilograms! Equivalent to the weight of several apples! Really worthy of being a veritable Apple champion.

Oh, stop it. The more you write, the more greedy you become. I went to wash my hands and eat apples.

My bodyguard was praised by the teacher in the composition class.

Its legs are pink, conical, soft and have excellent elasticity. The head is round, soft and yellow. My head is as big as table tennis, I turn a blind eye, my mouth is like a number "3", and there is a red heart on my face, which makes people laugh and cry. Hands are rosy and fingers are as round as plum blossoms. Looks like a stick figure.

After I got the trampoline, I was very happy and began to play. If you want it to bounce, you must first press its head with your hands, and your legs will be deformed from conical to cylindrical. Release your hand again and it will fly. When flying, its hand will swing up and down, like a bird spreading its wings and flying. When it flies down, it doesn't land smoothly, but falls at will. If it is a real bird, it will definitely break into pieces. Look at it lying on the ground, its head and legs still swinging back and forth. It's really like a bird blindfolded and flying to stand up. It is really interesting!

I like this trampoline very much because it is very interesting.

With the continuous progress of science and technology, many high technologies appear in our lives. Today, I will talk about our washing machine.

The washing machine is an indispensable thing in the family, and it helps us a lot. My washing machine, square body, wearing silver-gray clothes. There may be a scene in some movies where a person walks from one side of the washing machine to the other and comes to a magical world. Although our washing machine is not as powerful as the washing machine on TV, it is not bad.

My washing machine can be reserved or pre-washed, as well as Eco, rinse+,soaking and other functions. I don't know what these mean, but they should be very powerful. There are many different washing methods: such as children's washing, color washing, healthy washing, night washing and so on. As long as you turn on the power, pour in the laundry detergent and find the right washing method, you don't have to worry. Is it convenient?

My washing machine has been used for at least three years and hasn't broken down. Unlike my old washing machine, it can't be used after a few days, and it has to be repaired. Thanks to the progress of science and technology, we have been given a convenient and practical home washing machine.

The introduction of one thing shows that the seventh onion is a very humble plant. It is so common and ordinary, but its function is great, and people like it very much.

This common plant can grow anywhere, just like a weed. In order to facilitate picking, people always plant it on the wall, in the corner of the garden, in the old foam box ... As long as there is soil, it can flourish.

The lower part of onion plant is milky white, but the upper part is blue-green. Its unique shape is always incompatible with other plants. Its leaves are closed tubes of different lengths, but they are all magical and have the function of regeneration. Every time I pinch off its upper body, a few days later, the broken part actually grows new green seedlings, which is even more magical than magic.

The roots of onions are milky white, thin and long, and deeply rooted in the soil. If uprooted, the soil will also be uprooted, like an onion follower, which can't be separated for a moment.

Although onions are inconspicuous, they are all delicious. Onion eggs and onion cakes are all fragrant. Sprinkle a handful of chopped green onion on the ribs soup; Braised fish are decorated with onions ... As far as I know, onions are added to these foods because they can refresh and make the food more delicious and beautiful.

This is onion, an ordinary plant, which can help people create delicious food, although it is unremarkable and unsightly. They are endless, emitting fragrance with their own bodies and serving our beautiful life. I read the truth of being a man from onions. We can't be decent people who are useless to others.

The introduction of things shows that the tails of the eighth animal are all different, long and short, thick and thin ... all kinds, and their functions are different. Some can keep balance, some can master the direction, and some can drive away mosquitoes.

Kangaroo's tail is about 120cm to 130cm long. Its tail is about the length of a skipping rope. When resting, this tail can support the body, and when jumping, it can help it jump more than 10 meters. And when in danger, kangaroos can also attack enemies with their tails.

Gecko's tail is slender and slender. When it is pulled by external force or hurt by the enemy, the tail muscles will contract strongly, which can make the tail break immediately and save the day. Its tail plays an active role in vertical climbing and sliding, and can also store fat.

The tail of a fish is as important as the rudder of a ship. When swimming, you can master the direction and speed by your tail. On the other hand, tuna is the fastest in the ocean. The speed can reach 70 kilometers per hour, which is similar to the speed of a car.

The tiger's tail is colorful and very beautiful. Seen from a distance, it looks like a yellow and black ribbon. But when this tail is put on the tiger, it becomes a hunting weapon. The bones in the tiger's tail are hard and can be used as whips, about half a meter long. If you hit them at once, you can directly tear off the spine of small mammals.

The leopard's tail looks like a yellow scarf. Leopard is famous for its fast running speed, and its explosive power can soar its speed to 300 kilometers per hour, which is faster than ordinary cars. The role of the tail is reflected. Its tail can help keep balance. If the leopard breaks its tail, it may starve to death because it can't run fast, resulting in no food.

Animal tails are really strange, and there are many mysteries in nature waiting for us to explore!

There is a special practical class today-coffee.

The color of raw coffee beans will change with picking time, luster, water content and so on. It's usually cyan, and there are some white ones. As the raw beans are roasted and fried into our common brown coffee beans, take a bite and have a taste. The taste is slightly bitter, but the bitterness recedes and gradually becomes a little sweet.

The packaging of coffee beans is also very distinctive. There will be several small holes in its outer packaging bag. The teacher said that these are air holes, which are used to prevent moisture. The packaging bag also indicates the taste of coffee beans and the factory date when the coffee beans are made.

Next, it is the process of making coffee by hand. First, we have to grind coffee and grind coffee beans into powder. In the process of grinding, we use a manual bean grinder, which is difficult to grind at first, and gradually becomes easy. After the coffee beans are ground into powder, put the coffee powder into the filter cup, then slowly pour in warm water, and slowly leave the water in the filter cup into the coffee cup.

After that, the teacher poured some coffee juice into each of our cups for us to taste. I tasted it and felt bitter to death, but gradually it became bitter and sweet, which made me want to drink a few more. ...

This is coffee, just like the coffee of life.

This paper introduces a description of things, bookmark 10, which can help people remember where all kinds of books are and can also be used as decoration. With it, people can read more conveniently.

Making bookmarks can be divided into the following steps:

The first step is to prepare white paper, colored lead, sequins of various shapes, pencils, ribbons or thinner textiles, scissors, transparent plastic paper and other materials and tools.

Step 2, cut the transparent plastic paper into 10~ 13 cm long and 3 cm wide for later use.

Step 3: Draw the white paper as big as the transparent plastic paper, and draw a gradient color on it with colored lead. You can also fill in your own name or some alphanumeric characters on it, or draw some small animals and plants (stickers will do) that are similar to gradient colors, stick them together with the transparent plastic paper that was put aside before, and then open them.

Step 4, put some small sequins and small animal patterns on the mouth of the bag, then glue the mouth of the bag, cut a small hole under the glued place so that the ribbon can pass through, and finally tie a bow.

This makes a simple and beautiful bookmark.

Who is the smallest mammal in the world? It's the Etruscan shrew.

Etruscan shrews are very small and light. It is only about 4-6 cm long, and its tail is 4-5 cm, which is almost as big as two knuckles of an adult. Etruscan shrews generally weigh 1 to 5 grams, which is lighter than a Lego villain.

At present, the smallest Truglia shrew found in the world is only 5cm in length, 2.5cm in tail length and only 1 g in weight.

The main food of Etruscan shrews is earthworms and insects. Because it's too small! So when it preys on earthworms, it is like a mouse hitting a snake. How do Etruscan shrews prey? It will bite its prey first, then spray venom with its fangs, and then drag it into its burrow after it loses consciousness.

The shrew eats a lot, eating two to three times its own weight every day. Eat whatever you see. If you put the mouse and the shrew in the same cage, after a long time, you will find that the shrew is staring at the shredded body of the mouse, so the shrew is also called "the man with a big belly".

Although a shrew looks like a mouse, if you think a shrew is like a mouse, you are all wet. Science has proved that shrews are not related to mice. Even the relationship between man and shrew is closer than that between shrew and mouse. From the appearance, the mouth of the shrew is sharper than that of the mouse; From the food point of view, shrews eat pests and mice eat crops; From the perspective of combat effectiveness, shrews are fierce predators with strong combat effectiveness, and their combat effectiveness is relatively weak compared with rats.

The life span of shrews is only 14 to 15 months, and the gestation period is about 24 to 25 days. Every year, shrews have 1 to 2 babies, and each baby has 4 to 8 babies.

I have a small alarm clock with a red gradient. She is exquisite and small, round, with a small bell on each side of the round head and a small hammer that can knock out the sound. Her belly is a transparent round glass cover with a slender second hand, a slightly shorter and thinner minute hand and a short and fat hour hand, just like three little brothers. In the orderly race against time, by the way, there is also a needle, which is used to set the time. Usually, it is always motionless. The small alarm clock looks nice and cute as a whole.

There are three buttons on the back of the clock. A button is used to adjust the time. Whenever the time is incorrect, the knob will be adjusted immediately. There is also a button, which can be pressed once every time to set the time, and can execute the time setting I ordered. Like a guard who strictly follows orders.

It has been with me since the first grade. As long as it's time for school, it will ring a sweet bell on time and wake me up from my dream. When I wake up, I will turn it off, then pack up and go to school happily. For almost five years, it watched me go out and come back every day. It witnessed and reminded me of all the important moments in the past and became my closest friend.

When I do my homework, it accompanies me, when I draw, it accompanies me ... for a long time, I like this little alarm clock more and more. Although it is not as easy to use and bright as before, I think it will always be the little sun in my heart. It will continue to grow with me, do my homework, play games, share the joy of victory and the quiet companionship of failure. Lovely friend, I hope you.

I believe you must have eaten eggs. The eggs you see are nothing, but they are very useful. Let's listen to the mystery of eggs today.

Eggs are one of the nutritious foods, much better than those junk foods. Eggs have a thin skin outside, which is also called thin shell structure. Although the shell of duck eggs is not so hard, the nutrition of eggs is not better than that of duck eggs. Standing still is much better than duck eggs.

The eggshell is also wearing a white and thin suit. Some people didn't believe it at first, such as me. Well, if you want to see that suit, you can do it in two ways. First of all, you can take the eggs that your parents are going to throw away after beating, touch them and stick them on the surface of the eggshell. You will find that it is like touching a thin layer of things, which is the egg suit. Method two, you can ask your parents to boil an egg for you. You will find that some eggshells are connected together, which is also an egg suit.

There are many nutrients in eggs. Egg white contains protein, double protein and so on, not to mention egg yolk. The body also contains more nutrients such as protein and double protein than egg white.

In short, there is too much nutrition without eggs.
