Before reading the text, let’s preview (预习) scientifically! Within the next quarter hour, follow these steps:
Look at the Title & Picture:
The title mentions a “Worker No. 55” and a “plant”. Does “plant” mean a factory or a living thing? Look at the picture—what do you see? Guess what the text might be about.
Scan(快速查阅) for Key Words:
Quickly look through the text. Find these important words from your vocabulary list: workshop, leaf, collect, root, send, rise, stem, mix, produce, sugar, product. Circle(圈画) them lightly. Seeing them first helps your brain recognize them later.
Think about the Process:
The text describes (描述) how something works. Look at the words you circled. How might they connect? For example: Where is the workshop (leaf)? What does the root do (send water)? Where does the water go (rise through the stem)? What do workers mix? What do they produce (sugar and oxygen—the product)?
Ask Questions:
Turn headings or key words into questions. “How does the plant make sugar?” “Why is oxygen a product?” Write your questions down. You will find the answers when you read carefully.
This preview helps you understand the science (how the “plant factory” works) and the English words faster tomorrow. What will you discover within the leaf workshop?
