Xunzi said in the "Persuasion of Learning": If you don't accumulate steps, you can't reach thousands of miles; If you don't accumulate small streams, you can't become rivers and seas. In other words, the road of a thousand miles is carried out step by step, and it is impossible to complete the journey of a thousand miles without the accumulation of small steps.

By extension, it is necessary to do things in a down-to-earth manner, step by step, not afraid of difficulties, not afraid of twists and turns, and perseverance in order to finally achieve the goal. As the top priority of Chongqing's "Six One Project", the paid internship activities for college students lie in their true meaning.

People are shaped by their own world, and we can't change the world, but we can change ourselves. Sometimes, what people are looking for is just the past in their memory, what they didn't think they thought about back then, but they will never forget it in the future, just because, the youth of the past, we can never go back, reminiscing like water, but the years have become water. We can't go back to the past, we can't see the future, but we can hold on to the present.

Looking at the flowers from the other side, it is better to smell the fragrance in the close-up hole, and those who have the courage to wait and attack, everything will come in time.

Internship is an experience that every Nanaran college student must have, because he understands the society in practice, allows me to learn a lot of knowledge that I can't learn in the classroom, and also opens my horizons and grows insight, which lays a solid foundation for me to further go into the society in the future. I think it's time for me as a college student to build my own 10-year development plan.

All in all, the January experience brings the harvest of January, spring and autumn, I came here in order to learn to be a man, and in order to be a better man, I will go back to school to continue to study, slowly accumulate, I believe I will continue to grow strongly. Just because there is no accumulation of steps, there is no way to thousands of miles; If you don't accumulate small streams, you can't become rivers and seas.

Many things happened during this summer vacation, both good and bad, and they all had a necessary impact on the development of society. There are many such things all around us.

For example, the place where we live: the clear river water has become smelly and dirty, the river behind the elementary school is a typical example, every day from morning to night is full of smelly and dirty water, people no longer go to the river to play as before, but do not want to pass by there every time, gradually, fewer and fewer people cross the bridge, the river is crying; Even the roads we usually walk have become filthy, on the streets, this mouthful of phlegm, that stall of shit, people have to walk cautiously, and the road is crying.

Recently, the environment has also become very bad: the first rain is acid rain, and in some places there are sandstorms and floods every few months, and there is soon to be a typhoon, and the earth is getting weaker and weaker. Since the 80s, China has successively formulated the "Standard Methods for Environmental Monitoring", "Environmental Pollution Analysis Methods" and "Environmental Monitoring and Analysis Methods", etc., but why are there still all kinds of signs?

Acid rain is extremely harmful to living organisms, known as the "air death", such as acid rain can make chemical changes in the composition of the soil, so that it can not be absorbed and utilized by plants; Acid rain can acidify rivers and lakes, which can affect the growth and development of aquatic organisms such as fish and shrimp, and cause death in severe cases. Acidified water threatens people's health and affects drinking; Acid rain directly harms the buds and leaves of plants, and in severe cases, kills patches of plants. There is also a need to control waste batteries, especially those containing mercury or cadmium, which is also good for the environment.

Acid rain is mainly caused by man-made discharge of large amounts of acidic substances into the atmosphere and exhaust fumes emitted by various motor vehicles, while sandstorms and floods are also caused by people cutting down trees in large quantities, and people throw dirty things into the river water when the river water becomes dirty, and people throw away batteries and things on the street.

From this point of view, these deadly "killers" that pollute the environment are all made by human beings, and if the earth becomes like this is caused by human beings, this sentence is not false at all, can't the cry of the river and all this make people wake up?

With the country's attention to environmental pollution and the improvement of public awareness of environmental protection, environmental chemistry has a long way to go. We should also start from now, start from small things, take the protection of the environment as our own responsibility, do our part for the social environment, and pay our own responsibility for the weakening of the earth!
