workshop
in the Leaf. There are 20 to 100 workers in each workshop. During the day, we should 3.collect
sunlight and CO₂. Then the workers from the Root 4.send
up water, and the water will rise up to the Leaf through the Stem. Then, we 5.workers
will mix water, CO₂ and sunlight. They are going to 6.produce
sugar and 7.oxygen
. Oxygen is very important to humans and animals, because they need it to 8.breathe
.We work very hard. It's going to get 9.
dark
soon. We will have a 10.rest

情境导语：Discover plants' secret factory inside leaves! How do they make food and air? Read to find out!
Student：Teacher, I want to retell the article about plants, but I'm a bit confused. Let me try!
Teacher：Go ahead! I'll help if you get stuck.
Student：Okay! The story talks about “Worker No. 55” in a plant. At 7:15, he starts work in Workshop 1001 in the Leaf. Many workers there collect sunlight and CO₂ during the day. Then, workers from the Root send water up through the Stem. They mix water, CO₂, and sunlight to make… sugar and oxygen! The plant uses sugar to grow, but oxygen is mostly for animals and humans.
Teacher：Great start! What happens when it gets dark?
Student：Oh right! The workers rest at night. But… wait—why don't plants need the oxygen they make? I thought they breathe too!
Teacher：Good question! Plants do use some oxygen, but they make much more than they need. Most is released(释放) for us.
Student：Hmm, that's surprising! Also, the text says “Workers”—are they like tiny robots? I imagine(想象) real people in uniforms!
Teacher：Haha, no! “Workers” here mean parts of the plant, like cells or chloroplasts. They work together like a team.
Student：Oh! So it's like a factory inside the leaf? No wonder plants are so important! Without them, we'd have no food or air.
Teacher：Exactly! Any other questions?
Student：Yes! If we do a research project, can we see plants making oxygen? Maybe with a light and a jar?
Teacher：Fantastic idea! Try it—you'll learn even more!

1. What time does “Worker No. 55” start work?
Quarter past seven / 7:15.
2. What two things do the “workers” in the leaf produce?
Sugar and oxygen.
3. Why does the text say the plant “doesn't need much” oxygen?
Because plants mainly use sugar to grow; oxygen is a byproduct for animals.
4. How is the plant's leaf like a “workshop”?
It has many "workers"(cells) that mix water, CO₂, and sunlight to make products.
5. 新考法·创新思维
Design(设计) a simple(简单的) experiment(实验)to prove(证明)plants produce oxygen.
