Ethnic Vietnam with four thousand year history of building and defending the country, during his long history with the good traditions handed down from generation to generation. One of them is the traditional loving human spirit of solidarity is expressed through the proverb: "aches tear".
As noted above, traditional human love, the spirit of solidarity, mutual assistance difficult times is one of the oldest traditions of our nation.
About proverb, this question has two layers of meaning, in terms of class layers literally means that we can see that it is right in every word that we do not need to infer anything. This class can understand the meaning of a tree, the fresh leaves can "cover" for the leaves do not heal torn to jointly overcome a rain storm that leaves do not fall off the other tear. From this literal class, we can infer the metaphoric layers proverb - a layer that is not shown directly, and the reader must infer based on class literally. With this proverb one can understand its allusions are talking about love, the spirit of solidarity to help each other when in trouble, tribulation. The rich shall help the poor, incomplete, help the needy.

There are many animals around us, most of them are useful. The closest to us, the dog helps us keep the house, or the cat helps us catch rats. And the birds indirectly created a daily meal for us, because it ate worms, ate rats that were harmful to leaves, and fed rice. And abroad, camels help us safely cross the arid deserts. And beyond that, fish, shrimp, crab provide us with aquatic resources, help enrich our country. And do you know, it is these little fish that eat harmful animals in the water, helping us to have a clean source of water to consume. And in the mountains, the elephants helped the natives a lot. Animals are very beneficial to us, but right now, they are decreasing in number, due to over hunting by humans. So we must have timely preventive measures to protect the animals. Objects are very beneficial for us, so please protect them
Advantages of renewable energy
The first advantage of renewable energy is that it can be renewable, has an extremely large reserve, can be endless. Forms of energy such as solar, wind, geothermal, ocean waves, rain... are available and free to use, without fuel costs. Biomass energy also has large reserves and low fuel costs. Compared to traditional energy sources such as coal, oil, natural gas, which are increasingly depleted, only meeting human energy needs for about 50-70 years, this advantage is a strength. outstanding.
The second advantage of renewable energy is that it is abundant and can be widely exploited in all different areas of the earth. For example, with solar energy, people can exploit it anywhere, as long as there is sunlight, it can be used to generate heat to make hot water, heating, and generating electricity through the system. Solar power with solar panels… Or with wind energy, this energy source has been used for hundreds of years to move sailing boats, hot air balloons, windmills for irrigation systems. … or the current trend is to produce electricity from wind in many countries around the world.
Despite many great advantages, renewable energy also has some disadvantages, such as:
Due to the influence of nature, renewable energy is less stable than traditional energy sources. Solar energy can only be exploited during the day on sunny days, and at night or on cloudy and rainy days, the system will not work. Or with wind energy, wind turbines can only generate electricity at times when the wind speed is in the range of 4-25 m/s. Wind speed must be at least 4 m/s for the wind turbines to start running smoothly and generate electricity, but if it exceeds 25 m/s, the turbines will stop working to avoid damage in windy conditions. strong.
Requires advanced technology and high cost is also a drawback of renewable energy. To take advantage of renewable energy sources to generate electricity, it requires advanced technology and relatively high investment costs. Currently, the cost of electricity generation from renewable energy is generally higher than the cost from fossil energy. However, the development of renewable energy in the global trend has helped to reduce costs and increase efficiency, gradually improving this shortcoming.
Serving the community is a community affair, so I would love to paripate in the job market. Last year, I paripated in the "Companion" organization. We have donated clothes, books to poor children in mountainous areas. We also organize evening classes for street children. In addition, we raise money for those in need. I feel very happy doing my job because I can see how happy the poor are when they receive these small gifts.
