Here are some key ways trees help us: First, trees clean the air. Their leaves filter harmful particulate matter and absorb gases like ozone and carbon monoxide. This makes the air we breathe fresher and healthier. Second, trees help fight climate change. They take in carbon dioxide through photosynthesis and store it in their wood. Older, larger trees store more carbon than young ones, so protecting old-growth forests is crucial. Third, trees manage stormwater. They reduce runoff by letting water seep into the ground slowly. This helps prevent flash floods and keeps underground water supplies steady. Finally, trees support biodiversity. Forests are home to about 80 percent of the world’s terrestrial plants and animals. Without trees, many species would lose their habitats. 31.What do trees absorb to help fight climate change? A. Oxygen B. Carbon dioxide C. Ozone D. Particulate matter 32.How do trees help with stormwater? A. They collect water in their leaves.B. They let water seep into the ground. C. They stop rain from falling.D. They carry water to rivers. 33.What percentage of terrestrial plants and animals live in forests? A. 50% B. 60% C. 80% D. 90% Passage 2 Tea is one of the most popular drinks in the world, and its discovery has a special connection to trees. According to a Chinese legend, Shennong, a legendary ruler, discovered tea about 5,000 years ago. One day, Shennong was boiling water while resting under a tea tree. Some leaves fell from the tree into his pot of hot water. He noticed that the water turned a light yellow color and smelled fragrant. Curious, he took a sip. The drink was refreshing and made him feel energetic. Shennong realized the leaves had medicinal value. He began to study them and found that tea could help calm the mind and aid digestion. Over time, tea drinking became a tradition in China and later spread to other countries. Today, tea is grown in many parts of the world, from China and India to Kenya and Sri Lanka. The tea industry provides livelihoods for millions of people. But few people remember that this beloved drink all started with a simple tree and a happy accident. 34.Who discovered tea according to the Chinese legend? A. Confucius B. Shennong C. Laozi D.

Homes Passage 3 The “Trees for Life” project is a global movement to protect and plant trees. It started because more than half of the world’s trees have been destroyed in the last 200 years. For every tree planted today, 30 trees are cut down. The project has three main goals. First, it aims to plant 100 million trees in the next 10 years. Volunteers from all over the world take part in tree-planting activities. Second, it works to protect old-growth forests, which store large amounts of carbon. Third, it educates people about the importance of trees and how to protect them. In Kenya, the project has helped local communities plant trees to stop desertification. The trees prevent soil erosion and provide food and firewood for families. In Brazil, volunteers are working to protect the Amazon rainforest, which is home to thousands of plant and animal species. The project’s leader says, “Trees are essential for our survival. We can’t live without them. By planting trees and protecting forests, we are saving our planet for future generations.” 38.Why did the “Trees for Life” project start? A. Because trees are expensive. B. Because more than half of the world’s trees have been destroyed. C. Because people wanted to make money from trees. D. Because trees were taking over cities. 39.How many trees does the project aim to plant in 10 years? A. 10 million B. 50 million C. 100 million D. 1 billion 40.What has the project done in Kenya? A.

Passage 4 How to Protect Trees in Daily Life Trees are our friends, so we should do our best to protect them. Here are some simple ways to help: First, save paper. Paper is made from wood, so using less paper means fewer trees are cut down. You can write on both sides of the paper, use reusable notebooks, and recycle old newspapers and books. Second, don’t harm trees. Never carve words or draw pictures on tree trunks. This damages the trees and makes them vulnerable to diseases. Also, don’t pull leaves or break branches. Third, plant trees. You can plant a tree in your backyard, school, or community. Choose tree species that are suitable for your local climate. Water the tree regularly and take care of it as it grows. Fourth, support forest protection. Don’t buy products made from illegal logging. You can also join local environmental groups that work to protect forests. Spread the word to your family and friends about the importance of trees. Remember, every small action counts. By protecting trees, we are protecting our own future. 42.Why should we save paper? A. Because paper is expensive. B. Because paper is hard to find. C. Because paper is made from wood. D. Because paper causes pollution. 43.What should we never do to trees? A. Water them. B. Carve words on their trunks. C. Plant them in backyards. D. Recycle paper made from them. 44.What can we do to support forest protection? A. Buy products from illegal logging. B. Join environmental groups. C. Cut down old trees. D. Use more paper. 45.What is the main idea of the passage? A. How to make paper from trees. B. Different kinds of trees. C. Ways to protect trees in daily life. D.
