The most important energy for human existence-solar energy
① Energy is one of the foundations of human survival and development. Since the 20th century, global population growth and economic development have greatly increased the demand for energy. Among all kinds of energy sources, petroleum and natural gas in fossil fuels are the main primary energy sources in the world today. According to the statistics of the World Energy Committee, according to the output of 1992 countries, the proven recoverable reserves of oil and natural gas can only be mined for 44 years and 60 years respectively. Although there may be new discoveries in recoverable reserves, the social demand is also increasing, especially considering the economic development of third world countries, the time for oil and gas fuel exploitation will not be long. Among fossil fuels, although coal is the most abundant, the serious pollution caused by coal combustion makes it unlikely to become the main energy source in the world. Although nuclear fusion reaction can provide clean energy, the main substance of nuclear fusion is deuterium, which is 4.2 trillion tons, but the research of nuclear fusion reactor is very difficult, and it is estimated that the commercialization of nuclear fusion power station will not be realized until the end of the next century. Therefore, when looking forward to the prospect of energy problems in 2 1 century, we may face a period when oil and gas resources are exhausted and nuclear fusion power generation has not been commercialized. In order to ensure that human beings have sufficient clean energy supply during this period, it is an inevitable choice to use solar energy to generate electricity.
Solar energy is the most important renewable energy, and all kinds of energy on the earth are closely related to it. In fact, the sun has played an extremely important role in the evolution of the earth, the reproduction of organisms and the development of mankind, and has also provided inexhaustible energy for mankind. The continuous high-temperature nuclear fusion reaction in the sun releases huge radiant energy with a power of 3.8× 1026 MW, of which only one billion reaches the upper atmosphere of the earth; When passing through the atmosphere, about 30% is reflected, 23% is absorbed, and less than half of the energy (8× 10 16 MW) reaches the earth's surface. Nevertheless, as long as we can use a few tenths of it, we can meet all the needs of human beings today.

[analysis]
This article is divided into two sections. The first paragraph explains that "using solar energy to generate electricity is an inevitable choice" from the perspective of other energy sources besides solar energy-fossil fuels and nuclear fusion power generation, which shows that solar energy is the most important energy source for human survival in a certain period of time (when fossil fuels are exhausted and nuclear fusion power generation has not been commercialized).
The second paragraph illustrates the content of "the sun provides inexhaustible energy for mankind" with specific figures.
There are more than two interpretation methods applicable to this article, and there are two main requirements in the title. What is the standard of this "master"? We know that the interpretation method serves the object, and the interpretation method that can directly and better reflect the object and its characteristics should be "main".
In the first paragraph, in order to explain the present situation and prospect of various energy sources, we use the methods of classification, examples and charts, but these methods can not directly explain the center of this paper. In the second paragraph, concrete figures are used to illustrate that "solar energy is an inexhaustible source of energy", thus illustrating the importance of solar energy to human survival today. Therefore, enumerating numbers is a main explanation method. Generally speaking, the first paragraph lists the shortcomings and limitations of various energy sources other than solar energy, and the second paragraph lists the advantages of solar energy. In stark contrast, the inexhaustible solar energy and exhausted oil and gas fuel, the cleanliness of solar energy and the serious pollution of coal, the utilization value of solar energy today and the failure to commercialize nuclear fusion power generation fully illustrate the center of this paper, so comparison is a major explanation method.
(2) This article is an expository article explaining things, which generally adopts a logical order.
(3) The content explained in the first paragraph is generally the shortcomings and limitations of various energy sources other than solar energy, but it is not the center of this article. The purpose of explaining these contents is to explain that "using solar energy to generate electricity is an inevitable choice", thus highlighting the importance of solar energy to human survival, so the central sentence of this paragraph should be the last sentence.
From this topic, we can realize that the content explained in the explanatory text must be related to the object of explanation, so we must contact the center of the article when looking for the central sentence and summarizing the meaning of the paragraph and the meaning of the level.
The advantages of solar power generation are not concentrated in this paper, but by comparing with other energy sources, we can know that solar energy is inexhaustible, clean and can be used today.
⑤ This little problem involves the language of expository writing, which is based on accuracy, some plain and some vivid. Combining the two words "possible" and "most important" given in this paper, we can see that these two words reflect the characteristics of accurate language and cannot reflect the vivid side, so the language expression in this paper is characterized by rigor and accuracy.
If there are similar topics in other articles, we should also take accuracy and vividness as the basis of analysis, and both can be reflected, otherwise it will show accurate characteristics.
The light of faith
week
Faith means believing that there are some things in life that are much more important than your own life, even the most important thing in life, worth living for and dying for if necessary. This kind of thing must be higher than our daily life, shining above our heads like the sun, moon and stars. We believe in it and look up to it, so it's called faith. But it is not as visible as the sun, the moon and the stars. It is just an idea in our hearts, so it is also called faith.
When it comes to faith, people often think of religions, such as Christianity, Buddhism, Islam and so on. In human history, in real life, religious belief is indeed the most common form of belief. However, the two are not exactly the same thing. In fact, having faith does not mean having faith, and people with faith do not necessarily believe in a certain religion. Once, I traveled to Putuo Mountain, a Buddhist resort. In a big temple on the mountain, monks were doing things for a benefactor. During the break, a young monk came to chat with me. I asked him, "It's so tiring to do things!" He casually replied, "Yes, it's not easy to make money." In a word, he doesn't really believe in Buddhism, and converting to Buddhism is just a means of making a living. After all, this little monk is cute and straightforward. Temples around the world are full of incense, but if you can hear the wishes of those who burn incense and worship Buddha, you will know that almost all of them are asking for very specific benefits from Buddha, and few people really have faith. On the same trip, I met another little monk. At that time, I was sailing by boat. The cabin is sweltering, and passengers squeeze into the only tap water pipe in the cabin to wash their faces. Holding a towel, he waited quietly. Finally it was his turn, and another passenger stepped forward and pushed him away. With a blank face, he retreated to one side and politely motioned with his hand, "Please, please." I witnessed this scene and my heart was in awe. I believe this young monk in blue-gray cassock is a true believer. Later, through conversation, this has been confirmed. I found that he is very talkative and has a deep understanding of Buddhism and life.
In fact, true faith does not lie in believing in Buddhism, God, God or other gods, but in believing that life should have lofty pursuits and ideal goals beyond the secular world. If religion is really valuable, it only provides a simple way to popularize this pursuit. But once it is popularized, it will easily become a superficial form, but it will weaken or even lose the spiritual connotation of pursuit. Therefore, people who really value faith will never blindly believe in a popular religion or other ideas, but seek and establish their own beliefs through independent thinking. Two thousand four hundred years ago, Socrates was executed by the Athenians for not believing in God. He doesn't believe in God, but he has his own firm belief that the value of life lies in loving wisdom and examining life with reason, especially moral life. At the trial, the court allowed him to die on the condition that he must give up his faith and publicize it, but he refused. He said that an unexamined life is not worth living, and life is worse than death. He gave his precious life for his beliefs.
Faith is the inner light that illuminates a person's life path. A person without faith is like walking in the dark, having no direction and no goal, drifting with the tide and living in a daze for a lifetime. Of course, it is not easy for a person to truly establish his own beliefs. It requires not only independent thinking, but also considerable experience and comparison. On the long road of life, it is not surprising that things that change faith often happen. In my opinion, a sincere attitude is really important on the issue of faith. The so-called sincerity, the first is serious, neither indifferent, dispensable, nor blindly believe with the crowd; The second is to be honest and never deceive yourself. With this sincere attitude, even if you can't find a clear ideology as a belief, you can still be regarded as a person with faith, because you are at least believing in a realm of life with sincere pursuit. In fact, in an era when faith is generally lost or even ridiculed, perhaps only among these sincere seekers and lost people can we find people with true faith.
1. How does the second paragraph prove the view that religion and belief are not exactly the same thing? Please analyze it in detail. (4 points)
Answer: the second paragraph lists two examples: the young monk who does things on Mount Putuo does not really believe in Buddhism, but only uses Buddhism as a means to plan his life; On the other hand, the humble and courteous young monk on board is a devout Buddhist who can deeply understand Buddhism and life. Both of them are Buddhists, but the former has no faith and the latter has faith, which is in sharp contrast and strongly proves that religion and faith are not the same thing.
2. The underlined sentence in the third paragraph is about the belief in underground sudra. What point does the article use it to prove? (3 points)
Answer: People who really value faith (never blindly believe in a popular religion or other ideas, but) seek and establish their own beliefs through independent thinking.
3. The author said: "What is really important is to have a sincere attitude on the issue of faith." How to understand the role of sincere attitude in building faith? (4 points)
Answer: having a sincere attitude is the premise of establishing faith. Only when a person has a sincere attitude towards faith, takes faith seriously, and honestly examines the faith he pursues in his heart, will he tirelessly seek faith, find the true faith, and gradually clarify the ideological form of his belief.
