3. Wonderful marine life: Coral

Coral, a seemingly ordinary but wonderful marine life, is a beautiful and precious gift given to us by nature. They not only add rich colors to our underwater world, but also are an important member of the marine ecosystem.

Coral is formed by the accumulation of calcareous shells secreted by a tiny marine organism-corals. These corals usually live in tropical and subtropical seas, live together in groups, and the shells secreted by them are constantly accumulating, forming the corals we see.

There are many kinds, shapes and colors of corals. Some corals diverge like branches, some bloom like flowers, and some are as hard as stones. In terms of color, corals can be white, pink, red, orange, green and so on. They shine in the sunlight on the seabed and are very beautiful.

the importance of corals to marine ecosystems cannot be ignored. First, they provide habitats for many marine life. Many fish, crustaceans and other marine life depend on coral reefs as their homes. In addition, coral reefs can also protect the coastline from wind and waves.

However, in recent years, coral reefs are facing serious threats due to global warming and marine pollution. Many coral reefs have begun to whiten, that is, corals die and their calcareous shells are broken down. This is a very serious problem, because the disappearance of coral reefs will have a huge impact on the marine ecosystem.

Generally speaking, coral is a wonderful and beautiful marine life, which not only adds color to the underwater world, but also is an important member of the marine ecosystem. However, we also need to realize that the importance of protecting coral reefs cannot be ignored. We should take measures to reduce carbon emissions and marine pollution in order to protect these precious marine creatures and their living environment.

4. Traditional cuisine in China: jiaozi

jiaozi, as a traditional cuisine in China, has a long history and unique flavor, and is deeply loved by people. It is not only a necessary food for festivals and celebrations, but also a common food in daily life.

Although the production process of jiaozi is simple, every link in it is full of unique skills and flavor. First of all, jiaozi's skin should be thin but not broken, which requires skilled skills and experience. Dumpling skin is usually made by mixing flour and water in a certain proportion, and then kneading and rolling to form a thin and tough skin.

The next step is the stuffing making in jiaozi. You can choose different fillings according to your personal taste, such as pork and green onions, chicken and leeks, fish and coriander. When making stuffing, it is necessary to mix meat stuffing and vegetables in a certain proportion, and add a proper amount of seasonings, such as salt, soy sauce, sesame oil, etc., and mix them evenly before use.

finally, the stuffing is wrapped in the dumpling wrapper to form a semicircular jiaozi. Jiaozi also pays attention to the wrapping method, so it is necessary to pinch the edge of the dumpling skin tightly to avoid the stuffing from leaking out when cooking. When jiaozi is cooked, it should be cooked with boiling water. After jiaozi floats, it should be cooked for a while until the dumpling skin becomes transparent.

There are many ways to eat in jiaozi. You can dip it in vinegar and Chili oil directly, or stir-fry jiaozi with other dishes to form different flavors. In addition, jiaozi can be made into fried dumplings, pot stickers and other different shapes and tastes.

generally speaking, jiaozi, as a traditional food in China, not only has a long history and cultural connotation, but also has a unique production technology and flavor. It is an important part of China's food culture and one of the indispensable delicacies in people's daily life. Jiaozi is one of people's favorite foods, both in festivals and daily life.

5. magical plants: mimosa

mimosa, a seemingly ordinary plant, hides many magical things. It is a common ornamental plant and is loved by people because of its unique touch and reaction.

mimosa is a perennial herb, which usually grows in a warm and humid environment. Its leaves are long and consist of many small leaves, usually light green in color. The most striking feature of mimosa is its tactile response: when the leaves of mimosa are stimulated by the outside world, the leaves will be closed immediately, as if shyly avoiding the outside world. This reaction is caused by the swelling and pressure changes of the cells in the leaves of mimosa, which is a natural defense mechanism.

besides tactile response, mimosa has many other magical features. For example, it can adjust its growth rhythm according to the light intensity and time. Under strong light, mimosa will slow down the growth rate to avoid excessive evaporation of water; In weak light, it will speed up its growth to make full use of light resources. In addition, mimosa has good adaptability and vitality, and can survive and reproduce even in harsh environment.

mimosa plays an important role in nature. It can be used not only as an ornamental plant to beautify the environment, but also as a medicinal plant. In traditional medicine, mimosa is used to treat headache, fever, stomachache and other diseases. In addition, mimosa also has the function of preventing insects, which can effectively control the number of some pests.

However, in recent years, due to excessive picking and environmental pollution, the number of mimosa is decreasing. This has aroused people's concern about the protection of mimosa and its ecological environment. In order to protect mimosa resources, we can take measures such as limiting picking, strengthening the protection of laws and regulations, and promoting artificial cultivation.

In general, Mimosa is a magical plant with unique tactile response and adaptability. It is not only a part of nature, but also an important element in human culture and medicine. We should cherish and protect this magical plant resource.
