They are easy but helpful. First, I save water. When I wash my hands, I turn off the tap. I also use the water from washing vegetables to water my family’s plants. This way, we don’t waste much water. Second, I save paper. I write on both sides of my notebook paper. When I have old paper, I give it to my teacher. She says the paper can be recycled to make new paper. Third, I don’t use too many plastic bags. When my mom and I go shopping, I take a cloth bag. Plastic bags are bad for the earth, so I try not to use them. These small actions make me happy. I think if everyone does like this, our earth will stay clean and nice. 1.What does the writer do to save water? _____________________________________________________________ 2.How does the writer save paper? _____________________________________________________________ 3.Why doesn’t the writer use too many plastic bags? _____________________________________________________________ 4.How do the writer’s small actions make him/her feel? _____________________________________________________________ 5.What does the writer think about small environmental actions? _____________________________________________________________ 二：书面表达 生活中，我们可以通过一些简单的小事为保护环境出一份力。请以 “My Small Environmental Actions” 为题，写一篇英语短文，分享你在日常生活中做过的环保小事。 写作要求： 1.内容完整：至少写出 2 件你在日常生活中做的环保小事（如节约资源、减少浪费等），并简单说明这些小事如何帮助保护环境； 2.结构清晰：开头可以总述 “做环保小事很有意义”，中间介绍具体的环保行动，结尾表达你对环保小事的看法或未来的打算； 3.语言规范：使用简单、易懂的英语词汇和句式，避免超纲单词，字数不少于 60 词； 4.书写工整：语句通顺，标点正确，卷面整洁。 基础性作业 一、词汇拼写（每空一词） 1.planet 解析：“地球；行星” 对应的英文单词为 planet，此处为可数名词单数（特指地球）。 2.increase 解析：“增加；增长” 译为 increase，will 后接动词原形。 3. effect 解析：“影响；效果” 常用名词 effect，have a greateffect on 为固定搭配（对…… 有很大影响）。 4.flood 解析：“洪水” 译为 flood，前面有不定冠词 a，用单数形式。 5.storm 解析：“暴风雨” 译为 storm，根据后面的 “blew down”（过去式），此处用单数名词（特指昨晚的暴风雨）。 二、填空题（用括号里所给词的正确形式填空） 1.to protect 解析：考查固定搭配 choose to do sth.（选择做某事），choose 后接动词不定式。 2.using 解析：考查 instead of 的用法，of 为介词，后接动词 - ing 形式。 3.study 解析：考查 make sb. do sth.（使某人做某事），make 后接动词原形作宾语补足语。 4.thankful; thankfully 解析：第一空 felt 为系动词，后接形容词 thankful（感激的）；第二空修饰整个句子，用副词 thankfully（幸运地；感激地）。 5.reading 解析：考查 by 的用法，by 后接动词 - ing 形式，表示 “通过做某事”（表方式）。 三、单项选择（从选项中选最佳答案） 1.A（can） 解析：句意 “我们可以通过减少浪费来保护地球，因为它是我们唯一的家园”。can 表示 “能够；可以”，符合语境；mustn’t（禁止）、needn’t（不必）、can’t（不能）均不符合句意。 2.B（better） 解析：由 than（比）可知，此处用形容词比较级。good 的比较级为 better，意为 “我们城市的环境比以前更好了”。 3.B（turn off） 解析：考查动词短语辨析。turn off（关闭），turn on（打开），turn up（调大），turn down（调小）。句意 “离开教室时别忘了关灯 —— 这样省电”，故选 B。 4.C（to） 解析：考查固定搭配 be related to（与…… 相关），为固定短语，无其他介词搭配。 5.C（has held） 解析：由 since last year（自从去年以来）可知，句子用现在完成时，结构为 have/has + 过去分词。主语 our school 为单数，故选 has held。 四、完成句子（根据汉语意思补全句子，每空一词） 1.are related to 解析：“和…… 有关” 译为 be related to，主语 Many health problems 为复数，be 动词用 are。 2.cut down on 解析：“减少…… 的砍伐” 译为 cut down on，must 后接动词原形；cut down 侧重 “砍伐”，加 on 后强调 “减少（数量）”。 3.has got a fever 解析：“发烧” 译为 get a fever，由 now 可知用现在完成时（表示动作结果持续到现在），主语 he 为单数，用 has got a fever。 4.turn off 解析：“关掉” 译为 turn off，remember to do sth.（记得做某事），后接动词原形。 5.play an important role in 解析：“在…… 中发挥重要作用” 译为 play an important role in，can 后接动词原形。 拓展性作业 一、阅读表达（根据短文回答问题） 1.He/She turns off the tap when washing hands and uses the water from washing vegetables to water plants. 解析：由短文第二段 “First, I save water.
