This passage tells the story of street trees giving up the virgin forest and happiness and standing on the roadside of two lanes. The only decoration is a shaking dust. They never feel sad about it and never give up their lives, because they think it is a sacred cause. Street trees play their own talents, tenaciously creating freshness and not being cherished for the city every day, giving people shade in summer and welcoming sunshine and light at dawn. They have been making contributions to mankind all their lives.
The spirit of street trees' obscurity, selfless dedication and perseverance is really admirable and touching.
There are such "fools" in our lives. Take the cleaner as an example. They get up earlier than ordinary people every day, so they put on their work clothes, pick up their big brooms and go to the street to change clothes. That's what they did. They work hard every day, sweep the streets silently, never complain or be lazy. They do this to beautify the urban environment, prevent garbage from invading the city, and let people breathe fresh air every morning and walk on a clean road, which makes people feel comfortable and happy. Cleaning workers work hard, asking for nothing in return, and don't need praise from others, because there is always one sentence in their hearts that inspires them: serving the people.
Einstein once said: "A person's value lies in what he has contributed to the whole mankind and society, not what he has taken from society." Street trees and cleaners are like this.
In fact, a person living in this world should not only think for himself, but also for others, and think about whether what he is doing now has brought confusion to others. Serving the people like street trees and cleaners is a meaningful life.
