They can make their own food through a process called photosynthesis (光合作用). They use sunlight, water and carbon dioxide (二氧化碳) to make food and oxygen. Trees are big plants. They have roots, a trunk, branches and leaves. The roots go deep into the ground to get water and nutrients. The trunk carries water and nutrients to the branches and leaves. Leaves are like little factories—they do photosynthesis. Plants help us in many ways. They keep the air clean by taking in carbon dioxide and producing oxygen. They also provide food, wood and medicine. Some plants even help stop floods (洪水) because their roots hold the soil tightly. We should love and protect plants. If we cut down too many trees, the air will become dirty and floods will happen more often. Let’s plant more trees and take good care of all plants. 1．How do plants make their own food? A. By using sunlight, water and carbon dioxide. B. By taking in oxygen and producing food. C. By getting water and nutrients from the soil. 2．What do the roots of trees do? A. Carry water to the leaves. B. Get water and nutrients from the ground. C. Do photosynthesis for the trees. 3．Why do plants help stop floods? A. Because they can take in lots of water. B. Because their leaves can stop rain from falling. C. Because their roots hold the soil tightly. 4．What will happen if we cut down too many trees? A. The air will become clean. B. Floods will happen more often. C. There will be more nutrients in the soil. 参考答案 一、单词默写 【答案】1. power；2. plant；3. oxygen；4. breathe；5. produce；6. leaf；7. root；8. provide；9. shade；10. important 二、词组默写 【答案】1. produce oxygen；2. provide...for；3. keep the soil in place；4. on hot days；5. breathe fresh air；6. take care of plants；7. without plants；8. give us shade；9. be important to；10. grow new leaves 三、单词拼写 【答案】A. 1. produce；2. breathe；3. provide；4. important；5. roots B. 6.
