Pollution hurts our planet and our health, but we can all do something to reduce it. Here are some easy ways for everyone. First, save water. Many people waste water without noticing—like leaving the tap (水龙头) on while brushing teeth. We can turn off the tap when we don’t use it. We can also collect rainwater to water plants. This helps save clean water. Second, reduce waste. Instead of using disposable (一次性的) things like plastic forks or paper cups, we can use reusable ones. For example, carry a metal water bottle and a cloth bag when going out. We can also recycle things like paper, glass and plastic—many communities have recycling stations. Third, help clean the environment. If we see litter (垃圾) on the street or in the park, we can pick it up and throw it into the right bin. We can also join clean-up activities with our classmates or family. These small acts can make our neighborhood cleaner. Last, spread the word. Tell our friends and family about how to reduce pollution. When more people join in, we can make a bigger difference. 1.What can we do to save water according to the passage? 2.Why should we use reusable things instead of disposable ones? 3.Where can we recycle paper, glass and plastic in many communities? 4.What can we do if we see litter in the park? 5.What will happen when more people join in reducing pollution 参考答案 一、词汇拼写 1.kill（解析：对应课文核心词汇 “kill”，意为 “导致死亡；杀死”，情态动词 may 后接动词原形。） 2.suffered（解析：对应课文核心词汇 “suffer”，意为 “遭受；受苦”，根据时间状语 last night 用一般过去式。） 3.cheap（解析：对应课文核心词汇 “cheap”，意为 “便宜的”，此处为形容词作表语。） 4.reduce（解析：对应课文核心词汇 “reduce”，意为 “减少；降低”，need to 后接动词原形。） 5.ton（解析：对应课文核心词汇 “ton”，意为 “吨”，不定冠词 a 后接名词单数，构成短语 “a ton of”（许多；大量）。） 二、用所给单词的适当形式填空 1.are killed（解析：动词 “kill” 用被动语态，主语 millions of animals 为复数，一般现在时的被动结构为 “are + 过去分词”。） 2.suffers（解析：if 引导的条件状语从句遵循 “主将从现”，主语 our environment 为单数，谓语动词用第三人称单数形式。） 3.cheap（解析：形容词 “cheap” 此处作表语，无需变形，与后文 pollution 形成转折关系。） 4.to reduce（解析：“need to do sth.” 为固定结构，意为 “需要做某事”，填动词不定式。） 5.using（解析：“think about doing sth.” 为固定搭配，介词 about 后接动名词形式。） 三、单项选择 1.A（解析：情态动词 may 后接动词原形，“kill” 意为 “杀死”，符合污染水对鱼类的危害语境。） 2.A（解析：一般现在时中，主语 many people 为复数，谓语动词用原形 “suffer”，“suffer from” 为固定短语（遭受……）。） 3.B（解析：根据句中 than 可知用形容词比较级，“cheap” 的比较级为 “cheaper”，意为 “更便宜的”。） 4.C（解析：“try one’s best to do sth.” 为固定短语，意为 “尽力做某事”，填动词不定式 “to reduce”。） 5.B（解析：“ton” 为可数名词，前面有基数词 two 时用复数形式 “tons”，构成 “two tons of”（两吨……）。） 四、完成句子 1.millions of tons of（解析：考查固定短语 “millions of tons of”（数百万吨之多的），注意 million 用复数形式且搭配 of。） 2.even worse（解析：考查固定短语 “even worse”（更糟糕的是），用于补充说明更坏的情况。） 3.stop eating（解析：考查固定短语 “stop doing sth.”（停止做某事），“吃” 用动名词 “eating”。） 4.think about taking（解析：考查固定短语 “think about doing sth.”（考虑做某事）和 “take part in”（参加），take 用动名词形式。） 5.has a big impact on（解析：考查固定短语 “have a big impact on”（对…… 有重大影响），主语为动名词短语，谓语动词用第三人称单数 “has”。） 拓展性作业 一、完形填空 1.A（解析：“smog”（雾霾）对人体健康有害，“health” 意为 “健康”，符合语境，其余选项与雾霾影响无关。） 2.A（解析：前文列举污染来源，此处补充另一个来源，“And” 表示并列关系，符合逻辑。） 3.B（解析：一般现在时中，主语 he 为第三人称单数，谓语动词用 “rides”，“ride one’s bike” 意为 “骑自行车”。） 4.C（解析：塑料垃圾对地球有害，“hurts” 意为 “伤害”，符合语境，与前文 “stop waste” 呼应。） 5.B（解析：树木吸收有害气体，会让空气更清新，“fresher” 为 “fresh” 的比较级，意为 “更清新的”。） 6.A（解析：旧衣服改造的袋子应是好看的，“nice” 意为 “漂亮的”，符合积极语境，其余选项为负面含义。） 7.B（解析：根据句中 than 可知用形容词比较级，“better” 意为 “更好的”，表示地球会变得更美好。） 8.A（解析：“make sb. do sth.” 为固定结构，意为 “使某人做某事”，填动词原形 “feel”（感到）。） 9.B（解析：此处引导宾语从句，从句中 do 缺少宾语，用 “what” 指代 “能做的事情”，符合语境。） 10.C（解析：保护地球的目的是让家园更健康，“healthier” 意为 “更健康的”，符合环保主题，其余选项不符合语境。） 二、阅读表达 1.We can turn off the tap when not using it and collect rainwater to water plants.（解析：根据短文第二段内容，直接提取节约用水的两种方式，注意语句简洁符合题干要求。） 2.Because it helps reduce waste and protect the planet.（解析：根据短文第三段，使用可重复使用物品的目的是减少浪费、保护地球，对应原文 “reduce waste” 核心信息。） 3.We can recycle them in recycling stations.（解析：根据短文第三段最后一句，“many communities have recycling stations”，可知回收地点为回收站。） 4.We can pick it up and throw it into the right bin.（解析：根据短文第四段，看到垃圾应捡起并扔进正确的垃圾桶，直接提取原文动作描述。） 5.We can make a bigger difference in reducing pollution.（解析：根据短文最后一句，“When more people join in, we can make a bigger difference”，直接对应题干问题。） 学科网（北京）股份有限公司 $
