新素养·思维品质 We can see all kinds of trees in schools, communities and parks. As an important part of nature, trees have a close relationship with human beings.
Why are trees helpful?
Humans depend on trees. First, trees provide wood for building houses, making sofas and producing paper. People also use the leaves and other parts of trees as medicine to treat illnesses.
Trees play a key role in ecosystems. Trees can take in carbon dioxide（CO₂）and make oxygen（O₂）to make the air clean. Trees can protect water and soil. Besides, they are home to some wild animals. The fruit and leaves of trees are food for cows and sheep.
Paper products made from trees are part of our daily lives. Let's take the family of Li Hua, a 15 - year - old middle school student, as an example.
How much paper does Li's family use every year?
Printing paper 800 pieces
Toilet paper 150 rolls(卷)
Kitchen paper 225 rolls
※One tree can make 750 rolls of household（家用的）paper.
※ One tree can make 4,000 pieces of printing paper.
How do trees make us feel?
When we have a lot of stress, we can go into the forest to breathe and touch the trees' lives. The growing process of trees makes us relaxed and hopeful. Trees are also part of human culture. Many works about history, fiction and poems have something to do with trees. These works express people's praise for nature and carry humans' feelings and memories.
As though a gust of spring wind swept it past overnight, bringing thousands upon thousands of pear trees into bloom(开花).
