300-word explanatory composition: 1 year-old me, 15-year-old me, 15-year-old dream, 15-year-old harvest ... how long/5 years, I have learned a lot and lost a lot. Now we are in the season of youth. Although we are still a little playful and have not fully realized the importance of learning, we all have to cross the first step in life-the senior high school entrance examination. Moreover, we middle school students are in the stage of learning and seeking knowledge, and the road to life is still facing many first steps. Therefore, we should firmly remember the innocent teachings of our parents and teachers and study hard in the youth season. Although learning is a very boring thing, we should seize this season of youth and study hard, because now is the best time for us to learn knowledge. Otherwise, we will regret for a lifetime that the first step in life was not taken well.

Now we need to cherish time more. Time is gone forever. Now we have only one year to study hard and only one chance to take the senior high school entrance examination.

So we should seize the youth and study hard. Many people regret that they didn't seize the good times when they were young. Time flies, and the lost will never come again. We should cherish every day of our youth!

Explanatory article 300 words 2 "Books are the ladder of human progress." I think: Pay attention to reading, unlike some people who just look around and seek pleasure. The process of reading is an aesthetic process, so we should devote ourselves wholeheartedly and not be influenced by the environment. People who study, the more they read, the more they die; Only by studying can people read more and live more.

Books have thousands of uses: transplanting life, keeping memory, stimulating thoughts, spreading knowledge, exchanging information and expressing inspiration.

Reading is a pleasure. When I study, I feel like the dew after a long drought, which will make me feel relaxed and happy. Knowledge also needs books. Every time I finish reading a book, the rich and colorful content and knowledge in it will be screened in wisdom. Whenever I see newer and more scientific content, I will delete the content of the previous book and instill new knowledge. "With copper as a mirror, we can know the instrument; Take history as a mirror and know history; Taking the sky as a mirror, we can know its condition; Taking wood as a mirror can break the spring and autumn period; Take the book as a mirror and know your true self! "

"Reading American literature is like drinking. The more wine is brewed, the purer it is; Wen, the longer the fragrance. " This sentence comes from the classic selection of children's literature in the past 20 years. As the name implies, this book has honed a classic in 20 years of ups and downs. This is one of my favorite books. "Time goes by, feelings remain unchanged", which makes me feel the greatness of the book. Extensive and profound literature tells me the past writing methods and the changes of the times, and I am worthy of being the first in the group of books. In reading: laughter, sigh, pain, anger, bitterness and feelings are varied. Reading is an indispensable part of reading, profound and true.

Early in the morning, the small dewdrops gathered on the green leaves are crystal clear, like bright pearls scattered on green silk, beautiful! The breeze blew, the leaves shook gently, and a few small dewdrops jumped into the grass playfully, and they were no longer too lazy to show their little faces.

As soon as the sun lifted the clouds, it came with a pure gold smile, which was a greeting. It looked affectionately at the earth that had slept all night and saw the small dew in the cool morning breeze. The round head, shaking from time to time, is very cute, especially its golden light, which is really pleasing. Little dewdrop looked at herself curiously, why there are so many suns on her body, and each one is golden. So it looked up, oh, how dazzling! Little dewdrop frowned. The sun laughed loudly, and even Feng's mother was amused by it, patting its head fondly, and the little dew took the opportunity to roll.

The face of the sun is getting redder and redder. Xiaolu is missing. Hey! Where did it go? Are they all hiding? Unless you take Sun's hand and run to the Blue Palace? Otherwise, how can there be so many shiny little things in the dark sky at night? They will wink naughtily, just like dew!

Explanatory text 300 words 4 "Eat!" As soon as the voice fell, my mother brought me a big bowl of food. This bowl of big dishes covers rice, and vegetables account for half. The small bowl I used simply can't hold it, and I like to eat all the food on top of rice, so I have to use a big bowl instead. I saw half a bowl of rice covered with vegetables, peeled prawns, two pink steaks, oily and shiny shredded mushrooms, several spoonfuls of pale yellow egg custard and several vegetables. Really delicious, delicious and nutritious! My mother kept telling me to eat quickly, so I wolfed it down and didn't want to eat any more. Mom just came to coax me to eat. Seeing that I really couldn't eat any more, she said, "Don't eat rice. Finish all the dishes for me! " I often eat too much, my stomach is full, and the food reaches my throat.

My mother tries to make me eat more and eat better, but there is one reason: I grew up thin and small, and it is my mother's long-term goal to make me fat and strong! My mother always said: as long as I like to eat something good for my health, she will try her best to buy it for me. My mother also put down the "rhetoric": I am not afraid that I can't buy it, I am not afraid that I am poor, and I am afraid that you will not eat it! So it's not surprising that my mother eats a big bowl of delicious food every day!

Ha ha, a bowl of vegetables, my mother's love for me, can be seen in general!

My father bought me a flying machine a few months ago.

This plane is black and its fuselage is streamlined. There are four shafts around, each shaft has a blade, and there is a rigid protective cover under each blade, which can reduce the damage to the flying knife during collision. A camera can be hung on the front and lower end of the fuselage, and there are two legs on the lower side of the fuselage to prevent the fuselage from being broken when landing.

My father and I went to an open space in the corn building to play with flying machines. As it is controlled by radio, the code must be checked first. I checked the code, and then I pushed the accelerator forward, and it staggered and made a heavy "buzzing" sound. I continued to push the throttle lever upward to increase the throttle, and it flew upward for more than ten meters. I released the throttle lever and pushed the steering wheel forward for about five seconds. Because it was the first time I controlled it myself, it took too long to push it. The plane flew forward like an arrow and almost hit the wall. Fortunately, I pulled the steering rod back in time to avoid hitting the wall. I tried several times and got an experience: you can't pull the steering wheel for a long time at once, you just need to push it gently. Suddenly the light of the plane flashed, and I was startled: no way, I'm dying! I immediately pressed the landing button, and it flew while lowering its height, and slowly stopped at the ground. I packed my things and went home.

This is a flying machine. I like it very much.

In modern life, people invented various glasses, such as mirrors, vacuum glass, laminated glass, tempered glass and plexiglass. However, I don't think these can meet the needs of modern high-tech life. Today, I will introduce you to the new glass I invented!

The first one is called atmosphere glass, which can change the atmosphere at home with your mood. When you are happy, you can hear cicadas singing in the treetops, birds singing in the treetops, smell the fragrance of the soil in the fields and flowers blooming on the hillside. Just like being in nature; When you are depressed, you can listen to beautiful music, humorous stories, or tell a few jokes to make you happy and let you put aside all your troubles. Maybe this kind of glass will really come out in a few years! The second kind is called fresh glass. I have to ask the people who are about to move, paint is not only harmful to health, but also smells bad. This kind of fresh glass solves this problem well. As long as this kind of glass is installed, the pungent paint smell can be removed within 24 hours, because the glass itself can drive away all kinds of odors. And there is a gap under the glass. If perfume is added irregularly, it will give off a charming fragrance!

Don't you have a home as fragrant as nature?

My living room is six square meters. Although the sparrow is small, it is well equipped and particularly comfortable.

There is a photo of Qi Hong of China football team on the door of my living room, because I am an admirer of Qi Hong. On the right side of the door are two big purple wardrobes with my beautiful clothes in them. On the right side of the wardrobe is a blue desk with a book I like to read. These books not only give me happiness, but also give me knowledge. There is also an eye protection lamp and many stationery on the desk. Whenever I do my homework, the eye protection lamp will give off bright light. The thick dictionary seems to say to me, "Here is the knowledge you want."

Opposite the desk is a single bed, brown, and the sheets exude a fragrance. There are beige curtains on the bed with white Dalmatians on them. They are holding little balls. You throw one and I pick one, which is very interesting. On the right side of the bed is a toy box with many toys in it. There are many dolls and game machines on the box, as well as chess, military chess, checkers, gobang and poker. After finishing my homework, I will lie in bed and play with these interesting toys.

This is my little world, how about it? Not bad!

If I want to mention my favorite fruit, it must be pitaya.

It looks like an egg that is about to burst, or like a lotus flower that is about to open. You see, it is red and dandan, like a confident torch. You feel pricked with your hand. It feels like a massage.

Cut the pitaya with a knife, then scoop a spoonful of pitaya with a spoon. Taking a bite at the place where white pitaya is added with black sesame seeds feels like eating jelly.

Once, I got 88 points in math. This is something I don't believe for a girl who has been in the top five exams. I went home sadly, and my mother asked me what was wrong. I told my mother the test results. My mother gave me a pitaya and said, "Eat it!" I asked my mother, "Mom, I got 88 points. How can you give me pitaya? " "Because, pitaya is a kind of comfort fruit, longevity fruit!" Mom replied. Since then, I have never scored below 90 points.

I always remember what my mother said. Eat a pitaya when you are angry, and your anger will go away.

I like to eat pitaya.

There is a bridge in Yulin, my hometown-Yun Xiang Bridge. It is located on the Nanliu River in the south of Yulin City.

One Sunday, my mother took me to visit Yun Xiang Bridge. I was so happy! We set out from home and walked for about ten minutes until we came to a bridge. My mother told me that this is the "Yun Xiang Bridge".

I ran to the bridge as fast as I could. I just think this bridge is like a link, connecting the magnificent Yuntian Palace in the north and the modern gymnasium in the south. This bridge is about 100 meters long and 30 meters wide. There are many columns on the railings on both sides of the bridge. I counted 65 on each side, and the pillars were carved with exquisite clouds. There are five lampposts on the sidewalks on both sides of the bridge deck. There are nine lights on each lamppost. They look like blooming flowers. How beautiful! There are three arches and two rows of piers under the bridge, which makes the bridge look more stereoscopic and beautiful. The Nanliu River under the bridge adorns our city like a green ribbon. ...

Yun Xiang Bridge is so beautiful. Be sure to come again next time.
