Reduce Use reusable water bottles (instead of plastic ones). Walk or ride bikes (instead of taking cars for short trips). Buy products with less packaging (包装). Reuse Use old glass bottles to hold small things. Pass old toys/books to younger kids. Repair broken items (like umbrellas) instead of throwing them away. Recycle Separate waste into "recyclable" and "non-recyclable" bins. Recycle old newspapers and magazines. Send empty ink cartridges (墨盒) to recycling centers. 考场练兵·实战训练 Let's go green in daily life! Everybody can do something to help protect the environment. It's easy — just follow three ideas: reduce, reuse, recycle. Here are some simple steps to take. Firstly, let's talk about reducing. We can save resources by using reusable water bottles instead of plastic ones. To help reduce air pollution, we could walk or ride bikes for short trips instead of taking cars. We should also buy products with less packaging (包装) — this cuts down waste a lot. Reusing is also a good way to live a greener life. It's important for us to reuse old glass bottles to hold small things. We can pass old toys or books to younger kids too — they'll love them! Instead of throwing away broken items, we should repair them (like fixing a broken umbrella). Finally, let's remember to recycle. We need to separate waste into "recyclable" and "non-recyclable" bins every day. Don't forget to recycle old newspapers and magazines. In order to recycle better, we can send empty ink cartridges (墨盒) to special recycling centers. It's all these small steps that make a big difference. Let's start today and enjoy a cleaner, greener world! 考场练兵·实战训练 用方框内单词或短语的适当形式填空。 hardly, desertification, single-use, second-hand, battery, electricity, electronic, deal with Our earth is facing many environmental problems.

To protect our home, we need to learn how to (3)________ these problems step by step. First, let's change our daily habits. We should stop using (4)_________ plastics as much as possible, because they are hard to break down and pollute the environment. When shopping, we can bring our own cloth bags instead of taking plastic bags from shops. We can also save (5)_________ by turning off lights and (6)_________ devices (设备) when we don't use them. For example, don't leave the computer on if no one is using it. Second, reusing and recycling are great ways to help the earth. If your old toys or clothes are still in good condition, you can sell them to (7)___________ stores or give them to people in need. When your electronic products like old phones stop working, don't throw them away easily. Their parts, such as the (8)________ inside, can be recycled and used again. Many people realize that small actions can make a big difference. Let's start with ourselves today, and do our best to make the earth a better place to live in! desertification deal with single-use electricity electronic second-hand battery hardly Bye-Bye！ 学习学康鹤彪 $
