I live in a small town. Last Saturday, my family and I joined a “Clean Park” activity. It was organized by our community to keep Green Park tidy. In the morning, we arrived at Green Park at 9 o’clock. Many people were there, like students from my school, teachers and other parents. We brought gloves to keep our hands clean and big bags to collect rubbish. My dad and I walked on the grass to pick up plastic bottles and paper. My mom helped sort the collected waste into different bins—one for plastic, one for paper and one for glass. My little sister, Amy, is only 7 years old. She made a colorful sign with crayons. It said “Please don’t litter!” and we put it near the park bench. After two hours of hard work, the park looked much cleaner. A worker from the park came over and gave each of us a small tree. He said, “Thank you for your help! Plant these trees at home, and they will grow to make the air fresher.” We thanked him and took the small trees home happily. I felt a little tired after the activity, but I was very happy. I learned that even small things—like picking up a bottle—can help make our park clean. Next time, I will ask my best friend Lucy to join the activity with us. 1.Why did Lily’s family join the “Clean Park” activity? A. To play games in Green Park B. To help keep Green Park tidy C.

Surprised and worried 参考答案 基础性作业 一、词汇拼写 1.duty 解析：“责任” 对应的英文单词是 duty，此处是固定搭配 “it’s one’s duty to do sth.（做某事是某人的责任）”，符合 “保护环境是每个人的责任” 的语境。 2.reduce 解析：“减少” 的英文是 reduce，属于动词原形；should 为情态动词，后接动词原形，故填 reduce。 3.leaky 解析：“漏水的” 是形容词 leaky，此处用来修饰名词 toilet（马桶），构成 “leaky toilet（漏水的马桶）”，符合 “浪费水” 的语境。 4.walk 解析：“步行” 的英文是 walk，为动词原形；can 为情态动词，后接动词原形，故填 walk。 5.encourage 解析：“鼓励” 的英文是 encourage，主语 Environmental clubs（环保俱乐部）为复数，谓语动词用原形，符合 “鼓励学生用环保袋” 的语境。 二、选词填空（选项：activity, protect, produce, fix, encourage） 1.activities 解析：many 后接可数名词复数形式，activity（活动）的复数为 activities，句意为 “我们在学校有很多有趣的环保活动”。 2.protect 解析：let’s 后接动词原形，“保护地球” 对应的表达是 protect the earth，符合 “通过种树保护地球” 的语境。 3.produce 解析：考查固定搭配 help sb. do sth.（帮助某人做某事），produce（产生）为动词原形，句意为 “使用可重复利用的餐具能帮我们减少垃圾产生”。 4.fix 解析：考查固定搭配 ask sb. to do sth.（让某人做某事），fix（修理）为动词原形，句意为 “请让工人修理洗手间漏水的水槽”。 5.encourage 解析：主语 Teachers（老师）为复数，谓语动词用原形，encourage（鼓励）符合 “老师鼓励我们加入环保俱乐部” 的语境。 三、单项选择 1.B（to reduce） 解析：考查固定搭配 learn to do sth.（学习做某事），learn 后需接动词不定式，故填 to reduce，句意为 “在环保俱乐部里，学生们学习减少污染”。 2.D（in order to） 解析：in order to 后接动词短语，表目的；A 选项 so 后接句子，B 选项 so that 后接目的状语从句，C 选项 to 后接动词原形但需省略 “producing” 的 - ing 形式，故 D 符合 “用环保袋带午餐是为了减少垃圾” 的语境。 3.A（litres） 解析：20 to 40 后接可数名词复数，litre（升，容量单位）的复数为 litres，litter（垃圾）不符合 “水量” 的语境，故填 litres。 4.C（no one） 解析：World Car-Free Day（无车日）的核心是 “不开车”，A 选项 someone（某人）、B 选项 anyone（任何人，用于否定 / 疑问句）、D 选项 everyone（每个人）均不符合语境，no one（没有人）符合 “无车日没人开车上学” 的逻辑。 5.B（to keep） 解析：考查固定句型 it’s one’s duty to do sth.（做某事是某人的责任），it 为形式主语，真正的主语是后面的 to do 不定式，故填 to keep，句意为 “保持环境整洁是我们的责任”。 四、完成句子 1.join in 解析：“加入（活动 / 俱乐部）” 对应的短语是 join in，主语 many students（许多学生）为复数，谓语动词用原形，句意为 “在加拿大，许多学生加入环保俱乐部”。 2.encourage; to use 解析：“鼓励某人做某事” 的固定搭配是 encourage sb. to do sth.，主语 Environmental clubs 为复数，谓语动词用 encourage；“使用” 为 use，故填 encourage; to use。 3.waste; an hour 解析：“浪费” 为 waste，can 后接动词原形；“一小时” 为 an hour，句意为 “漏水的马桶一小时会浪费 20 到 40 升水”。 4.instead of 解析：“而不是” 对应的短语是 instead of，后接动词 - ing 形式（driving），符合 “步行 / 骑车上学而不是开车” 的语境。 5.Keeping; healthy 解析：“让地球健康” 中，“让…… 保持某种状态” 用 keep，此处需用动名词作主语，故填 Keeping；“健康的” 为 healthy，句意为 “让地球健康是我们的使命”。 拓展性作业 1.B（protect） 解析：短文围绕 “环保俱乐部” 展开，核心是 “保护地球”，A（伤害）、C（破坏）、D（污染）均与环保主题相反，故选 B。 2.A（cloth） 解析：由前文 “No Plastic Day”（无塑料日）可知，学生不会用塑料袋，cloth bag（布袋）符合 “不用塑料” 的要求，故选 A。 3.B（drew） 解析：后文提到海报上的文字，结合语境，学生应是 “画海报”，A（买）、C（扔）、D（忘记）均不符合逻辑，故选 B。 4.C（different） 解析：“分类垃圾” 需要将纸、塑料、玻璃放进 “不同的” 垃圾桶，A（相同的）与 “分类” 矛盾，B（大的）、D（小的）不涉及分类逻辑，故选 C。 5.D（reusable） 解析：由后文 “They can be washed and used again”（可清洗重复使用）可知，此处指 “可重复利用的” 餐具，A（新的）、B（便宜的）、C（一次性的）均不符合 “重复使用” 的描述，故选 D。 6.A（big） 解析：固定搭配 “make a big difference” 表示 “产生重大影响”，结合语境，老师想表达 “小事也能有大作用”，故选 A。 7.B（cleaner） 解析：由 “and greener”（更绿）可知，此处需填积极意义的比较级，A（更脏）、C（更暗）、D（更吵）均为负面词汇，cleaner（更干净）符合 “环保让学校变美” 的语境，故选 B。 8.C（useful） 解析：后文提到 “我学会了如何保护地球”，说明加入环保俱乐部是 “有用的”，A（无聊的）、B（困难的）、D（危险的）均与 “学到知识” 的积极感受矛盾，故选 C。 9.B（keep） 解析：固定搭配 “keep doing sth.” 表示 “持续做某事”，结合语境，“我会每天继续做这些小事”，A（停止）、D（忘记）与环保态度相反，C（开始）不符合 “已经在做” 的语境，故选 B。 10.C（together） 解析：“一起努力让地球更好” 符合环保的集体理念，A（独自）与 “大家参与” 的逻辑不符，B（努力地）、D（快速地）不突出 “共同行动”，故选 C。 二、阅读理解（阅读选择，共 4 小题，每小题 2 分） 1.B（To help keep Green Park tidy） 解析：由短文第一段 “It was organized by our community to keep Green Park tidy” 可知，活动目的是 “保持格林公园整洁”，A（在公园玩游戏）、C（从公园买小树）、D（见莉莉的老师）均未提及，故选 B。 2.C（She sorted the waste into different bins） 解析：由第二段 “My mom helped sort the collected waste into different bins” 可知，莉莉的妈妈 “把垃圾分到不同垃圾桶”，A（捡塑料瓶）是莉莉和爸爸的行为，B（做警示牌）是妹妹的行为，D（帮别人拿袋子）未提及，故选 C。 3.B（Small trees） 解析：由第三段 “A worker from the park came over and gave each of us a small tree” 可知，公园工作人员给了 “小树”，A（彩色蜡笔）、C（新手套）、D（大垃圾袋）均未提及，故选 B。 4.A（Tired but happy） 解析：由最后一段 “I felt a little tired after the activity, but I was very happy” 可知，莉莉的感受是 “累但开心”，B（无聊又难过）、C（生气又兴奋）、D（惊讶又担心）均与原文不符，故选 A。 学科网（北京）股份有限公司 $
