My favorite vegetable - cucumber
There are many kinds of vegetables in the world, but my favorite is The vegetable is cucumber. Do you know why? I'll tell you now.
My favorite vegetable is cucumber. Some cucumbers have curved shapes and some are straight. The cucumber is about one foot long when it grows up. It is emerald green all over, and its tail is relatively smooth. The remaining part has many small thorns, and it feels a little prickly to the touch! A small yellow flower blooms on the top of the cucumber. The flower has five petals, like a trumpet playing happily. In the past, we could only eat cucumbers in autumn, but now there are vegetable greenhouses that can be planted in February, erected in March, and will bloom and bear fruit in April and May for sale on the market. At this introduction, I remembered a riddle: a vine is crawling, with yellow flowers and green dragons. Do you know what it is? Then let me tell you the correct answer, it is cucumber.

It is tender inside, has a refreshing and slightly sweet taste, and has the effect of quenching thirst.

Cucumber is also a "good food for weight loss and beauty" and has been favored by people for a long time. Modern pharmacological research believes that fresh cucumbers contain a substance called propionic acid, which inhibits the conversion of sugar into fat.
There are many ways to make cucumbers, such as cucumber peeling, short rib cucumber soup, cucumber filling dumplings, knife-cut cucumber... But my favorite is small rib cucumber soup. By the way, I also want to tell you that cucumbers cannot be eaten with tomatoes, because the vitamin C inhibitor enzyme in cucumbers can destroy the vitamin C nutrients in tomatoes, and cucumbers cannot be eaten with celery.

At night, there are cars coming and going on the city streets, but the local people say that the noise is getting louder and louder. The more the merrier, why? It turns out that noise can allow people to enjoy wonderful music through a kind of glass. This music will also change songs and volume according to various situations. For example: when people sleep, the noise will turn into a lullaby, with a softer sound. Play at a high volume; when students are doing their homework, as long as the volume is adjusted to the lowest level, no matter how loud the sound is outside, nothing can be heard indoors.

For example: there are pines and cypresses trimmed like pagodas, but there is no military parade. Roadside trees, because according to the aesthetic point of view of Chinese painting, this is not desirable. The Nanpu Bridge is the first bridge across the Huangpu River in Shanghai. It was completed in November 1991.

7. Use the explanation methods such as listing numbers, giving examples, and making metaphors learned in this lesson to use "The Self of a Whale"
Hello everyone! , I am a whale from the sea. We are mammals. Some people say we are fish. That is wrong, because we breathe with lungs like cattle and sheep, and we are still viviparous. I weigh a lot, We weigh 30,000 kilograms and are 14 meters long. I am a baleen whale, and I mainly eat small fish and shrimps. But my brothers, the toothed whales, are different. They mainly eat big fish and sea animals, and sometimes they even eat us! It is most beautiful when we breathe. My nose is on the top of my head. After a while, we will exhale. When we exhale, a water column is formed, which is vertical, thin and high, like a fountain in the garden. We It can spray up to 15 meters high, but my brothers are completely different. The water column they spray is slanted, thick and short. Their water column is much shorter than ours, so experienced fishermen can judge based on the size of our water column. Determine our type and size. Sleeping is a compulsory course for us. We always gather together with our heads in and tails out, floating on the water like a circle. This is not only conducive to our escape, but also conducive to our breathing. .In fact, our temperament is very gentle. We will not take the initiative to attack humans. We would like to make friends with humans. If you want, you can go to the sea or a marine museum.

For example: Set Kedas Waterfall hung its head helplessly among the mountains. , like an old man on the verge of death, described as haggard and dying. 9. I want an explanatory essay about electrical appliances with listed numbers
Computers, which were regarded as mysterious by the Chinese a few decades ago, have gradually unveiled their hazy veil and entered the homes of Chinese people.
Computer is another name for computer. Because of this, people often associate it with addition, subtraction, multiplication and division, which makes students like us who have studied hard for sixteen or seven years full of expectations for it.
When I was in primary school, computers used written arithmetic. When I was in middle school, I learned abacus and reached the highest level of "seeing a few numbers without dividing them by nine." For speed, we had to use a logarithmic slide rule with poor accuracy. Participants were asked to perform calculations with high precision, and a hand-operated computer was used for multiplication and division calculations.
This kind of hand-cranked calculator lives up to its name and is specially used for "calculations" of multiplication and division. Although it was very noisy to use and its speed was far inferior to the calculators that are widely used today, it was a rare "treasure" at the time.
In the spring of 1979, the secretary of the party branch in my hometown saw me using a hand-cranked computer at work. After returning to my hometown, he really praised me and said that I could shake that wheezing foreign thing so well. Whispering, you can calculate a number of hundreds of thousands in the blink of an eye, it’s really amazing! The first computer knowledge enlightenment education for me came from relevant magazines in the 1960s and 1970s. In an introductory material about applied computers, I saw an introductory article about using computers to prove the four-color theorem outside the graph.
The four-color theorem is a truth recognized by the geography community. It states that only four colors are needed to draw a map, but the necessary proof was lacking at the time. With the help of computers, it took more than two hours to prove it.
If artificial proof is used, it will really require generations of successive generations. In the mid-1980s, computers, with their inherent mystery, entered the doors of some government agencies in provincial capitals. People welcomed the arrival of the first batch of computers like a new daughter-in-law.
At that time, many units stipulated that computers must be installed in special rooms, with wooden floors and appropriate elevation; operators must wear overshoes to enter, and their hands and faces must be clean; etc. At the leadership meeting of a certain unit, there was an oral decision that non-staff members were not allowed to enter the computer room to prevent "virus" infection.
The widespread application of computers is a manifestation of social progress. People's application of it started with general operations such as delivering reports and printing files, and gradually expanded to all aspects of application in the industry. The work efficiency is getting higher and higher, and the magic of computers is more and more displayed.
Our highway industry uses computer graphics, which eliminates many troubles such as base drawings, pencil drawings, tracing, and printing, etc., and is extremely fast. Moreover, computer graphics have high precision and beautiful pages, making them very popular among users.
People no longer need to print and mail materials when conducting business exchanges. They only need to send an email, which is convenient and trouble-free. A USB flash drive weighing tens of grams can record considerable and rich information and become a good helper for the carrier to use at any time.
Learning to use a computer requires hard work, otherwise it will be difficult to uncover its mystery. In 1998, when I was still on the job, my original employer equipped me with a computer, which gave me the opportunity to get in touch with and learn to use computers.
At that time, I was already a clumsy fifty-five years old. In order not to leave lifelong regrets, I started learning computers like a primary school student. It has been seven years.
In the past seven years, although I have never stopped learning and operating, and I can’t remember how many masters I have “obeyed”, I am still not very proficient in fingering, not to mention that there are still many fields that I have not yet explored. Computers will always remain a mystery to us unless we make the effort to explore them in depth.
Only then did I understand why people should "live and learn". Computers store rich knowledge and entertainment content.
There is nothing wrong with using computer games, but it should be done in moderation. There is an old saying that opening a book is beneficial, which means that when you read, you will always gain something.
Nowadays, it is not impossible to say that "turning on the computer is beneficial." In your spare time, when you are bored, it is also a kind of gain to turn on the computer and play, practice your fingering, and stimulate your intelligence.
Before the Spring Festival, I suddenly got two laptops. One was purchased and the other was "gifted" by my naughty little disciple: "Please put a laptop on the table. Then put your chin on the notebook. Okay, this is my Spring Festival gift to Master - a notebook for your head."
Computers and computer pads both make me happy. I believe that just like the popularization of color TVs, the popularization of computers will not be too far away, and it will be faster than the popularization of color TVs.
