Senior one expository composition 1 Snow-white body exudes fragrance. Besides our loveliest gardenia, which other flower has this feature? Every year in the middle and late May, we can see one or two petite and beautiful gardenias in the hands of men, women and children.
We like gardenia because it is beautiful and fragrant. However, do you know other characteristics and functions of gardenia? Next, I'll introduce it to you!
Gardenia, also known as peony, likes a warm and humid environment with sufficient light and good ventilation, but it is suitable for living in a slightly cloudy place, resistant to semi-shade, afraid of stagnant water and relatively cold-resistant. There are eight main types of gardenia, gardenia, gardenia, gardenia, gardenia, gardenia, gardenia, gardenia, gardenia, gardenia, gardenia, gardenia. What we often see is gardenia. The branches are green and the young branches have scaly hairs. Leaves opposite or 3-bladed; Oblong-lanceolate or ovoid-lanceolate, 7 ~14cm long and 2 ~ 5cm wide, with tapering or short top, whole margin, white edge, smooth edge and leathery; There is a short handle; Stipules are membranous, and a sheath is synthesized at the base. Flowers are large, solitary in branches or leaf axils, about 7 cm in diameter, white and very fragrant; Calyx lobes 6, linear; Corolla lobes broadly oblanceolate; Stamens 6, anthers linear; The ovary is inferior, with cells 1, thick style and rod-shaped stigma. The fruit is obovate or oblong, 3 ~ 7 cm long and 1 ~ 1 in diameter. 5 cm, yellow, with high longitudinal edges, thick pericarp and persistent calyx. The flowering period is from May to July. Distributed in central and southern China. Variety characteristics: Different from the original variety, the flowers are big and heavy and do not bear fruit.
Gardenia is not only small and exquisite, but also can be used as medicine, which has the effects of purging fire and relieving annoyance, diminishing inflammation and reducing fever, clearing away heat and diuresis, cooling blood and detoxifying. This shows that gardenia really plays a great role.
Gardenia is luxuriant in foliage, evergreen in all seasons, elegant in fragrance, with green leaves and white flowers. It is particularly beautiful and lovely, and it is an excellent landscaping material in the courtyard. Suitable for terrace, Chi Pan, roadside configuration, can also be used as a flower fence, potted plants, bonsai viewing, flowers can also be used for flower arrangement, wearing decoration. The peel can be dyed yellow, and the wood is hard and meticulous, so it is a good carving material.
China lunar calendar divides a year into four seasons, and each season is divided into three parts: Meng, Zhong and Ji. July, August and September of the lunar calendar are autumn, and August 15th is just in the middle of autumn, so it is called "Mid-Autumn Festival", also called "Mid-Autumn Festival".
There are three main theories about the origin of Mid-Autumn Festival. This is a famous legend of the Goddess Chang'e flying to the moon. After the Goddess Chang'e flying to the moon, Hou Yi missed him day and night, so he asked the maid to offer a table under the moonlight, with all kinds of fruits that Chang 'e loved most. Neighborhood villagers also put tables and fruits in their own yards to bless the beautiful and kind Chang 'e.
Since then, it has been like this every year, handed down from generation to generation. On August 15th every year, everyone goes to the moon to worship Chang 'e, because this day is the Mid-Autumn Festival, so people designate this day as the Mid-Autumn Festival.
Second, the Mid-Autumn Festival originated from the activities of offering sacrifices to the land gods in ancient autumn. In the traditional farming society, spring sowing, summer harvest, autumn harvest and winter storage are the main labor activities. The situation of land harvest is very important for people who make a living from it. Therefore, people still have deep awe of the land. Every spring when sowing seeds, people will sacrifice to the land god and pray for a bumper harvest. This activity is called "spring prayer".
Autumn is the harvest season, and we should also offer sacrifices to the land god. Thanks to God's protection, it is called "Autumn Newspaper". August 15 is the autumn harvest season, and every household should offer sacrifices to the land god. Therefore, the Mid-Autumn Festival may be a custom passed down from the ancient Autumn Newspaper.
Third, the Mid-Autumn Festival is related to the ancient custom of offering sacrifices to the moon. Worship the sun at vernal equinox and the moon at autumnal equinox. Since ancient times, the autumnal equinox has been the traditional "Festival of Sacrificing the Moon". According to historical records, as early as the Zhou Dynasty, ancient emperors had the custom of offering sacrifices to the sun at the vernal equinox, to the earth at the summer solstice, to the moon at the autumnal equinox, and to heaven at the winter solstice. Today's Mid-Autumn Festival evolved from the traditional Mid-Autumn Festival.
According to the exact historical records, the original Mid-Autumn Festival was set on the day of the Autumn Equinox. However, because this day in August of the lunar calendar is different every year, there may not be a full moon. It is a great failure to sacrifice the moon without it. Therefore, the Mid-Autumn Festival was later moved to August 15 every year, thus giving birth to the Mid-Autumn Festival.
August 15th is the Mid-Autumn Festival, so it is called Mid-Autumn Festival or Mid-Autumn Festival. The moon on August 15 is rounder and brighter than the full moon in other months, so it is also called "moonlit night" and "August Festival". On the eve of Mid-Autumn Festival, people try to reunite with their families, which means bimonthly. August 15 is also called "Reunion Festival".
Mid-Autumn Festival is a traditional folk festival of Han nationality and ethnic minorities. As early as the Three Dynasties, China had the custom of "Twilight in Autumn". The moon at night is to worship the moon god. In the Zhou Dynasty, every Mid-Autumn Festival night, activities to welcome the cold and offer sacrifices to the moon were held. In the Tang Dynasty, it was quite popular to enjoy and play with the moon in the Mid-Autumn Festival. In the Southern Song Dynasty, people gave mooncakes to each other as a symbol of reunion. There are activities such as enjoying the moon and visiting the lake in the evening. Since the Ming and Qing Dynasties, the custom of Mid-Autumn Festival has become more popular. Many places have formed the custom of burning incense, planting Mid-Autumn trees, lighting tower lanterns, putting sky lanterns and walking on the moon. Dragon dancing and other special customs. Nowadays, the custom of playing under the moon is rare. However, feasting and enjoying the moon are still very popular. People drink alcohol in the middle of the moon to celebrate a better life, or wish their distant relatives health and happiness and spend a good time with their families.
In ancient times, there were sacrifices to the moon and Yue Bai. Put up a big incense table, with moon cakes, watermelons, apples, pears, grapes and other sacrifices, among which moon cakes and watermelons are absolutely indispensable. Watermelons are also cut into lotus shapes. Under the moon, the moon god is placed in that place of the moon, and the red candle burns high. The whole family takes turns in Yue Bai, and then the housewife cuts the reunion moon cakes. The chopping people count the number of people in the family in advance, and they can't chop more or less. The connection between moon cakes and Mid-Autumn Festival was in the Ming Dynasty. According to relevant information, there was a kind of mooncake filled with fruit in Beijing at that time. People made mooncakes for their own use during the Mid-Autumn Festival, and they could also be given to relatives and friends as gifts to express reunion and congratulations. At that time, moon cakes were irregular in size and shape, with great differences and special names. For example, in the Mid-Autumn Festival in Jiexian County, Shanxi Province, local people have the custom of having their families sit around and eat reunion moon cakes. They make many moon cakes, which are also very interesting, such as crescent moon cakes for men, gourd moon cakes for women, and moon cakes such as "Monkey King" and "Male Prostitute" specially prepared for children. Many names, and so on.
Today is Christmas Eve. Let me tell you the reason for Christmas Eve.
Singing Christmas songs on Christmas Eve is an ancient tradition. According to incomplete statistics, there are thousands of Christmas songs recorded in the world; There are more than fifty songs that have been sung for a long time. The most famous Christmas song is Silent Night. This song has six bars, and three bars are usually popular (the first, second and sixth bars in the original text). The main idea of the first paragraph of lyrics is: Christmas Eve, Christmas Eve! Let's rest in peace and wake up alone. Good curly-haired son, sleep, sleep peacefully, sleep peacefully. The first sentence is Silent Night, so the song is also called Silent Night. From then on, Christmas Eve was named "Christmas Eve"
China is not a traditional country. However, Hong Kong and Macao were influenced by Britain and Portugal respectively during the colonial period. Christmas Eve is a day that young people, children and even everyone will celebrate. Hundreds of thousands of Hong Kong people will go to East Tsim Sha Tsui to enjoy Christmas lighting and enjoy a buffet in the hotel. Many people will exchange gifts on Christmas Eve. Young couples will go to Tsim Sha Tsui to enjoy Christmas lights and hold Christmas parties, or go to Lan Kwai Fong and other places for revelry. Catholics will attend religious gatherings such as good news.
Christmas Eve also allows many young people to "taste the forbidden fruit for the first time" on this night, so there is a local saying that "Christmas Eve, the night of virginity", and every year, organizations such as the Hong Kong Chamber of Commerce and Mother's Choice receive a lot of help. In Macau, every time you step into the streets of1February, you will be decorated with a strong European Christmas atmosphere. Christmas trees, Christmas trees, ribbons and colored lights can be seen everywhere. On Christmas Eve, young people go shopping with friends in the Central District. They also like to go to the discussion pavilion and St. Paul's archway to enjoy the good news of Christmas organized by the Catholic Church and organizations respectively.
At midnight, Catholic churches in various parishes in Macao hold Christmas midnight mass, especially the cathedral with the largest number of people, and Christmas bells are ringing all over the city. Even non-Catholic citizens like to go to church to feel the religious atmosphere of Christmas. Macau's Imperial City is also a sea of people, and young people go to bars to celebrate the holidays.
After listening to my introduction, do you know anything about Christmas Eve? Then let's have a happy Christmas Eve together!
Now flooding, air pollution, noise and other problems seriously endanger human health, such as demons attached to human beings, and some people died at their hands. As the saying goes, "the magic is one foot high and the road is one foot high." The solutions to these problems boil down to two words: greening. Don't underestimate it, it has many benefits.
Greening means planting trees and grass. Planting these plants containing chlorophyll is of great help to improve air quality.
First of all, green plants can carry out photosynthesis in the sun, absorb carbon dioxide and release oxygen. Studies show that plants can produce 5 tons of oxygen per growth 1 ton. Each hectare of forest can absorb 1 ton of carbon dioxide every day and produce 0.735 ton of oxygen; Each hectare of grassland can absorb 0.9 tons of carbon dioxide and produce 0.6 tons of oxygen every day. Adequate and clean oxygen can keep people healthy.
Secondly, the forests on the earth can emit 654.38+700 million tons of terpenes into the atmosphere every day, which has unparalleled bactericidal ability and exciting effect.
Then, green plants have a good filtration and absorption effect on dust and dust in the air, which can prevent working dust from spreading into the air. According to the measurement, when the atmosphere passes through the forest belt, the amount of dust and floating dust can be reduced by 32%-52% and 30% respectively.
Do you know that?/You know what? Do you know that?/You know what? Forest negative oxygen ions can reach10-100000. Negative oxygen ions can regulate the excitation and inhibition of nervous system and improve the function of cerebral cortex. Medical experts simulate the magical effect of forests and introduce negative oxygen ions into wards. The results show that when the ratio of negative oxygen ions to positive oxygen ions in the environment is controlled at 9: 1, it can promote the treatment of patients with asthma, burns, ulcers and trauma.
In addition, greening can also absorb noise and reduce soil erosion. Contribute to the greening of China, and that touch of green will slowly tell you its benefits. Experts pointed out that the fragrance of flowers can cure diseases and protect health, but it can also cause diseases and harm the body. The fragrance of flowers in the air is too strong, and the oxygen content is relatively reduced, which will stimulate people to hyperventilate, reduce the oxygen content in the blood, and cause symptoms such as headache, dizziness and nausea. Some people with allergic constitution will be stimulated by some pollen, resulting in allergic asthma and allergic rhinitis. For example, orchids can help relieve hot cough, and may also play a catalytic role. The smell of orchids is too strong, which makes people feel too excited and dizzy The fragrance of lilies is exciting, but if it lasts too long, it will make people dizzy and may also make people insomnia.
The total solar eclipse on July 22nd provided an excellent viewing opportunity for the public in the Yangtze River valley of China. Cao Jun, an engineer from Beijing Planetarium, introduced five highlights of the total solar eclipse that should not be missed.
Bailey beads flashed instantly during the total solar eclipse.
Look at Bellevue. The phenomenon of Bailey beads will appear twice, once before food appears and once after the birth of light. Cao Jun said that the phenomenon of Bailey beads is that the sun is gradually obscured, leaving the last point, like a small bead. This is because the moon itself is not a particularly smooth sphere, with mountains, plateaus and valleys on it, so the edge is undulating, so it is impossible to cover the whole photosphere at once, and the rest of the light finally survives through the gap in the valley. This is a very beautiful sight, which usually causes cheers from the audience.
Sun chromosphere during the total solar eclipse.
Second, look at chromosphere. During the total solar eclipse, the very bright photosphere is blocked, and a relatively weak chromosphere will be seen. Cao Jun said that the colored ball itself is rosy and very beautiful. It can only be seen within ten seconds before and after the food-eating stage and the luminous stage. Usually we don't have a chance to see chromosphere unless we use expensive equipment, such as prominence mirrors.
Prominences photographed during the total solar eclipse
Third, look out. Cao Jun said that the prominence is actually on the chromosphere, but it fluctuates like a flame. Prominences are not fixed, sometimes there are, sometimes there are not. But generally speaking, we can all see a flaming prominence during a solar eclipse.
Corona taken during total solar eclipse
Fourth, look at the corona. The corona is the atmosphere outside the sun, and it is a very white color. Cao Jun said that during the total solar eclipse, the sun was like a black hole, but the circle around it was white, which was the corona. You can see the corona with the naked eye without any special equipment.
Look at the sky and the environment. Cao Jun said that during the total solar eclipse, many bright stars could be seen in the sky. After the eclipse, the sky will darken quickly, and Venus and Mercury will appear in turn, which is very bright. At this time, it is not completely dark, especially on the horizon. Generally speaking, it will be orange and orange-red, which is very beautiful.
Life has all kinds of bridges. On passages, stone bridges and footbridges; In the park, covered bridges, flower bridges and zigzag bridges; In this way, "heart bridge" and "magpie bridge" can be formed.
A bridge between land and water. When roads and roads are cut off by water. Intelligent human beings stand by and watch the water. So the bridge came into being. A bridge is the connection between land and land. Bridge is the love between river and road. The bridge is a post road for ships and vehicles to nod. This bridge is where rowers wave goodbye to pedestrians. Humans who have suffered from trekking. Thanks to this bridge.
Bridges not only facilitate people to cross the river, but also make the scenery more beautiful and even develop into places of interest. Some bridges are surprisingly built, some have no piers at all, some are made entirely of marble, and some are even designed in an X shape. This must be incredible for those who invented the wooden bridge because of a brainwave at that time.
Every time I walk through the overpass, I can't help but want to stop and look at the passing vehicles and pedestrians, which makes me feel the rhythm of the rapid development of the city, and the face of the city is changing dramatically day by day. Especially at night, against the background of street lamps and advertising neon lights, cars with lights on under the bridge are like meteors passing by. Really beautiful!
In Shenzhen, in order to see the viaduct more clearly, I boarded the footbridge parallel to the viaduct on Shennan Road in Hengjia. Looking at the speeding train from the south, I was filled with emotion: the builders of the special zone built overpass after overpass on their own. I want to be proud of this railway bridge and the people of Shenzhen!
Composition 8 is the only diving seabird that can't fly. * * * There are 17 varieties, distributed in the southern hemisphere, with a large number in the South Pole.
Penguin's head, neck, back and wings are all black, but its chest and abdomen are white, and it looks like a gentleman in a tuxedo.
The average height of adult penguins is 70-80 cm; Weighing 4-6 kilograms. Penguins less than one meter tall weigh only 4-6 kilograms, but look at their chubby bodies ... I can't believe they are still good swimmers!
I didn't know where penguins lived before. Who are their natural enemies? Later, I checked the information and understood everything.
Penguins are butterfly-shaped pits made of small stones on the flat ground, with a diameter of about 40-50 cm. This is the penguin's home, which professionals call a "nest".
Penguins have two natural enemies, one is some animals, the other is the weather. Skua is the main natural enemy of penguins on land. When penguins leave their nests to hunt, penguin eggs in their nests can easily become food for skua. Little penguins, who have just been able to make a living independently, have also become prey of skua on land because of their lack of life experience. In addition, young penguins are often swallowed by fierce seals after entering the sea.
Weather is another natural enemy of penguins. Snowstorms that often occur in summer often freeze penguin eggs or chicks.
From this point of view, little penguins are really helpless to natural enemies, and the mortality rate is as high as 50%!
Nowadays, after human beings landed at the South Pole, they brought more misfortune to penguins. Tens of thousands of penguins died because of the virus brought by humans. Have humans become natural enemies of penguins?
Humans always observe and know penguins blindly, but they often ignore their protection and love, which disturbs their normal life.
It's good to like it, but if you like it, you have to make them live better. If these lovely animals are "extinct" by human beings, not only those of us who like penguins will be heartbroken, but all mankind will regret it.
Not only penguins, we should love every kind of animal. Don't "cherish it when you lose it".
If you like it, you have to make them live better.
In our daily life, the necessities of our life are nothing more than daily necessities, but they can also be found in strange nature.
In some areas of North China and Northwest China, there is a kind of "vinegar tree". The fruit of this tree is spherical. When the fruit is ripe, the local people squeeze the fruit of the "vinegar tree" into juice, which can be used instead of vinegar after concentration.
There is another seasoning that people like very much, that is monosodium glutamate. There is a kind of "monosodium glutamate tree" growing on Gongshan Mountain in Yunnan. This kind of tree is about 25 meters high, its bark is dark brown, just like Cooper's, and its leaves are like a human palm. This kind of leaves is very thick, and the so-called "monosodium glutamate" is hidden in these leaves. When local people cook, they pick a few leaves of "monosodium glutamate tree" from the tree and put them in the dish, which tastes as delicious as monosodium glutamate.
Get dressed. What if there is no main course?
If someone says that rice grows on trees, do you think it's incredible? There is a tree growing in Malay Peninsula, Indonesia Islands, Malaysia and other places. This tree is more than 20 meters high and belongs to Palmae. Its service life is about 10-20 years. Its trunk is hollow and soft, mostly starch. This tree blooms only once in its life and dies soon after it blooms. The local people cut down the tree before it died, took out the starch in the tree and soaked it in clear water. This kind of rice is almost the same as rice, so a tree can produce 200-400 Jin of rice!
There is also a very interesting tree-"Egg Tree". As the name implies, the fruit of this tree is like an egg. The skin of this egg is hard and smooth. Unlike real eggs, this kind of "egg" tastes like a melon and can be directly picked and eaten. In some countries in Europe and America, many people plant this kind of "egg tree". Imagine there are "eggs" on the tree, isn't it interesting?
Having said that, do you have an impulse to plant them all at home?
Senior one expository composition 10 The sea is boundless because of tolerance; The sky is beautiful because of tolerance and continuous clouds; The reason why the mountain stands tall is because of tolerance and the collection of fine soil, dust and sand. People-to learn tolerance, can shine brilliantly.
Tolerance is like water. Tolerance means forgiving others' mistakes, not complaining about others, not haggling over every ounce, and being kind and generous. Tolerance is like water, and encountering contradictions is often more effective than excessive retaliation. It is like a clear spring, slowly erasing each other's temporary hostility and making people calm and sober.
Tolerance is like fire. Because further tolerance not only means not caring about personal gains and losses, but also means warming others' hearts with your own love and sincerity. Calm as water tolerance is rare; The tolerance of giving charcoal in the snow is even more commendable and moving. Tolerance can melt the freeze in each other's hearts and shoot the heat of love into each other's hearts. Isn't this tolerance exactly what people need in this competitive era? Choosing tolerance means choosing care and warmth, and also choosing the vastness of life.
Tolerance is poetic. Tolerance is a poem of life. The highest state of tolerance is not only manifested in the handling of something in daily life, but also sublimated into a life attitude towards others. The meaning of tolerance is not limited to the understanding and care between people, but the tolerance and fraternity of all life between heaven and earth.
Tolerance is a science. For small mistakes, small mistakes, you can happily tolerate each other. But for big mistakes, big mistakes must be considered clearly. Tolerance is not shielding or hiding, but helping.
Of course, tolerance should be "strict with yourself and lenient with others". Forgiving yourself easily is not tolerance, but cowardice. "Be lenient with others" depends on the object, and those who are tolerant and do not cherish tolerance are promiscuous. Tolerance to those who are not worthy of tolerance is tolerance; It is indulgence to tolerate unforgivable people. Therefore, tolerance itself is also a science.
Because of tolerance, complex life becomes pure; Because of tolerance, monotonous life is beautiful. What a beautiful color tolerance has given life!
The world is so wide, but there is something wider than him-the human heart. Let's learn tolerance!
Tolerance is the virtue of human cultural inheritance. The sea has become vast because of tolerance; The sky is beautiful because of tolerance and continuous clouds; The reason why the mountain stands tall is because of tolerance and the collection of fine soil, dust and sand. The world has eternal beauty because of tolerance.
