Do you want our school to be greener and more beautiful? I have some cool ideas .（抛出问题，引起下文） First, let's talk about “reduce”. We can reduce electricity by turning off lights when we leave the classroom. Also, let's reduce paper waste. This way, we use less paper and save more trees. And don't forget to reduce single - use things. Bring your own water bottle and lunch box to school instead of using disposable (一次性的) ones. Next is “reuse”. Old paper can be reused for art homework. Draw pictures or make crafts on it. We can also reuse old books. What about old bottles? Turn them into pencil holders!Then comes “recycle”. We can recycle food waste by putting it in the special bins. The school can use it to help plants in the garden grow. Also, recycle plastic bottles and cans. Put them into the right recycling bins so they can be made into new things.（提出的建议） If we all do these small things—reduce, reuse, and recycle—our school will become a super green place. Let's start now and make our school full of green!（表达祝愿） 01 基础知识精讲-句型 1.核心环保行为词汇 减少浪费类：turn off lights（关灯）；reduce paper waste（减少纸张浪费）；avoid single-use items（避免一次性物品）；bring own water bottle（自带水瓶）；use reusable lunch box（使用可重复利用饭盒） 重复利用类：reuse old paper（重复利用旧纸）；reuse old books（重复利用旧书）；make crafts（制作手工艺品） 回收利用类：recycle food waste（回收厨余垃圾）；use special bins（使用专用垃圾桶）；recycle plastic bottles（回收塑料瓶）；recycle cans（回收易拉罐） 2.常用句型 提出环保行动建议 We can ________ to make our school greener. 我们可以通过________让学校更环保。 Let's ________ when we leave the classroom. 离开教室时，我们要________。 It's good to ________ instead of using disposable ones. 用________代替一次性用品是个好办法。 说明行动意义 By , we can save more trees. （通过，我们能拯救更多树木。） Putting food waste in special bins helps ________ grow. （把厨余垃圾放进专用垃圾桶能帮助________生长。） Reusing old things can make them . （重复利用旧物能让它们。） 02 基础知识精讲-语法 1.祈使句（用于校园环保指令） 肯定式：动词原形 + 其他。例：Turn off lights.（关灯。）；Reuse old paper.（重复利用旧纸。） 否定式：Don't + 动词原形 + 其他。例：Don't waste paper.（不要浪费纸张。）；Don't use disposable bottles.（不要使用一次性瓶子。） 2.情态动词 "can" 的用法（表达可行的环保行为） 意为 “可以、能够”，后接动词原形，用于说明校园中可实施的环保行动。 例：We can recycle plastic bottles.（我们可以回收塑料瓶。）；We can make pencil holders from old bottles.（我们可以用旧瓶子做笔筒。） 提分练 一、单项选择 （ ）1.We ______ turn off the lights when leaving the classroom.
