If we want to protect our home planet, we are supposed to reduce waste, reuse dailylife items and recycle reusable materials. In the past, many factories poured harmful chemicals into rivers. Lots of plastic waste and litter were thrown everywhere. Thick smog appeared in some cities because of waste gas. People suffered from water and air pollution. Some sea creatures got trapped in plastic bags. Natural resources were wasted in a wasteful way. Few people realized the importance of environmental protection at that time. Thankfully, more citizens have changed their attitudes. The government has made strict laws against pollution. Factories are required to deal with waste before disposal. We sort rubbish and put waste into recycle bins. We try to reduce the use of plastic products. Old glass jars and cloth bags can be reused for storage. Paper, metal and plastic are collected so that they can be recycled. It is clear that small actions can make a great difference to our environment. Some teenagers wonder what we students can do for environmental protection. We should conserve natural resources and avoid being wasteful. Those habits that we develop in daily life will influence our sustainable future. Although environmental tasks are challenging, every small effort counts. We can inform more people of causes and effects of pollution. As junior students, we decide to take ecofriendly actions and spread environmental knowledge to the public. In conclusion, only joint efforts can slow down global warming and build a greener world. 文本说明：紧扣单元核心话题，完全匹配单元标题Reduce, Reuse, Recycle、Section A 污染成因对话、Section B 回收与环保行动阅读文本，完整融入单元核心词汇。 Unit 4 单词自查清单（默写专用） 基础单词 & 变形 reduce, reuse, recycle, reusable, recyclable, waste, wasteful, pollute, pollution, chemical, harmful, smog, global, global warming, environment, environmental, protection, protect, resource, conserve, sustainable, ecofriendly, plastic, litter, disposal, citizen, law, sort, metal, storage, attitude, challenge, effort, inform, effect 专有名词 无 单元固定短语 reduce waste, deal with, because of, suffer from, get trapped in, natural resources, environmental protection, recycle bins, make a difference to, inform…of…, causes and effects, slow down, in conclusion 文章长难句分析（九下 Unit4 重点语法：被动语态、定语从句、宾语从句、sothat 目的状语从句、让步状语从句、it 形式主语） 句 1 In the past, many factories poured harmful chemicals into rivers.
