[2023·西藏] The “Great Green Wall of China” project is over forty years old. In this project, people plant trees in Northern China. Why are trees so important to us? Because it is healthy to live around trees. They can keep us healthy, just like doctors. So we call them “doctor trees”.
Trees can clean the air. For people in large cities with air pollution, trees can be very important. Workers are planting trees not just in city parks. They are also planting trees along streets to help clean the air.
Some scientists think that trees not just help clean the air. They are also good for our health. A study shows that people in hospitals feel better when they can see trees from their rooms. And people with trees near their homes usually exercise more.
Scientists are also studying the healthy effects (作用) of trees on human minds. One effect of trees is that they make people feel happy and relaxed. When people go through the neighborhood with more trees, they will walk slower and talk more often with each other.
