Today's human beings are the generation that has the richest life and the most convenient actions in history, all thanks to scientific progress and technological inventions. With the development of scientific and technological civilization, human beings have become more and more unscrupulous in accessing the earth's resources and doing whatever they want. Although it satisfies the needs and convenience of human life, it affects the life and activities of human beings and shakes the structure of the life community between man and the environment, causing the overall harmony to be greatly harmed and threatened. This is what modern scientific and technological civilization has paid the painful price. The most serious killers of nature’s ecology are global warming and deforestation. How countries in the world respond to this ecological crisis must rely on joint research and prevention. Due to the large-scale deforestation of forests and the process of obtaining arable land, humans have disrupted the original delicate balance formed by nature, especially the circulation of oxygen, which slowed down the circulation of oxygen even more. According to the survey, about 500 to 1 billion trees are cut down each year. In addition, the forest fires have caused a staggering number of global forest disappearances, and the speed of tree planting and afforestation lags far behind. The earth has begun to warm up, and mankind should actively plant trees, afforestation to open a window for the earth to prevent indiscriminate cultivation. And deforestation of forests and implement planned afforestation, planted a large number of trees to play its role in purifying the atmosphere. At the same time, research and development of clean and pollution-free alternative energy sources, such as solar energy, geothermal, wind, water power, tides, and hydrogen fuel, can effectively avoid the production of carbon dioxide and make full use of resources. You must also know how to save energy in your daily life. Try to walk, ride a bicycle or take public transportation. You must maintain good vehicle performance when driving, choose the most energy-efficient vehicle, and turn off the engine when parking and waiting. In summer, you should wear it. For clothes that do not absorb heat, install energy-efficient lighting and reduce the use of air conditioners. How do we prevent continuous global warming? We must consider the balance between economic development and environmental protection to slow down global warming. Specific measures include reducing energy waste, increasing energy efficiency, turning off lights or taking public transportation, and so on. That is what each of us can do as long as human beings have a sense of crisis, and at the same have the intention to maintain the natural landscape and delay the warming of the earth, so I believe that the goal will achieve. We know that the ecological environment is deteriorating. Actively protecting the natural environment is a global priority. In addition to preserving a place for wild and endangered species to survive, it also allows us to understand the importance of greening the environment more clearly. The generation has a comfortable and healthy growth environment. Therefore, it is necessary not only to promote the use of fewer products that produce global warming but also to promote the concept of greening to curb the effects of global warming and at the same time improve a high-quality and quiet living space.

A person’s life can’t always go smoothly and smoothly, and there will be a lot of unevenness. When the road ahead is flat, you keep smiling, and when the road is uneven you need to keep smiling. In this song, the musical form is A-B-A-C-Coda. A part is a peaceful part, no test, no pressure. B part is one of most stressful part, there are entrance examination, final examination, cram school tests, a lot of tests, but the scores are worse. The next A part is make a preparation on next tests and examinations, hope it could be better. C part is the tests and examinations begin. Finally, Coda part is I get the 1st place on every tests and examinations. This is my life.
