What do the workers mean to a plant in real life? 2.Why does the writer use “workers” in the passage? No, the workers mean cells (叶绿体细胞). To make the passage more interesting and easier for the readers to understand. Think and Share 1.What does “plant” mean in the title? In the title, “plant” has a double meaning. Usually it means a living thing like a tree or flower. Here, it refers to a “factory” where “workers” make food for the plant and oxygen for us. A pun(双关语) is a word with more than one meaning. It’s a clever way to make the passage more interesting. 2. In what other ways do plants help the world? For people: provide food, clean the air and help stop the floods... For climate: reduce the effect of climate change... For animals: provide food and homes for animals... Language Points 1. Now workers from the Root send up water. send作动词,意为“寄,发送; 传达; 派遣”。 E.g.
