(3-5 sentences) 参考解析 基础练 一、找出每组中不同类的单词或短语。 1.答案：D 解析：A（学生）、B（书）、C（图片）均为名词（表人或物品），D（有趣的）为形容词，类别不同，故选 D。 2.答案：D 解析：A（小的）、B（大的）、C（不同的）均为形容词，D（小组）为名词，词性不同，故选 D。 3.答案：C 解析：A（读书）、B（画画）、D（讲故事）均为动词原形短语，C（做手工）为动词 - ing 形式短语，结构不同，故选 C。 4.答案：D 解析：A（班级）、B（教室）、C（圆圈）均为名词（表场所或形式），D（二十）为基数词，类别不同，故选 D。 5.答案：D 解析：A（唱歌）、B（玩游戏）、C（分组坐）均为动词短语（表动作 / 活动），D（许多）为形容词，类别不同，故选 D。 二、根据句意补全单词。 1.答案：pupils 解析：由图片书信中 “There are twenty pupils in my class” 可知，此处需填 “pupils”（学生），“books”（书）与 “study together”（一起学习）的主体不匹配，故选 “pupils”。 2.答案：big 解析：跨学科结合数量逻辑，“班里有 20 名学生” 需 “大的（big）” 教室才能容纳，“small”（小的）无法满足容纳需求，与 “enough for all pupils” 矛盾，故选 “big”。 3.答案：read 解析：由书信中 “We read books and draw pictures here” 可知，“read books”（读书）是教室内的常规活动，“draw”（画）常搭配 “pictures”，与 “books” 不匹配，故选 “read”。 4.答案：telling 解析：“and” 连接并列结构，前半句 “are making” 为现在进行时，后半句也需用 “are telling”，“tell” 为原形，不符合语法一致原则，故选 “telling”。 5.答案：circle 解析：由书信中 “We often sit in a circle. Sometimes we sing songs” 可知，“围成圈（sit in a circle）” 是唱歌的常见形式，“group”（小组）与 “sit in a circle” 描述的场景不符，故选 “circle”。 三、汉译英。 1.答案：are; pupils 解析：“某地有某物” 用 “There be” 句型，主语 “twenty pupils”（二十名学生）是复数，be 动词用 “are”；“学生” 是 “pupils”（可数名词复数）。 2.答案：classroom; big; books; pictures 解析：“教室” 是 “classroom”，“大的” 是 “big”；“书” 是 “books”，“图片” 是 “pictures”，均为可数名词复数（“many” 后接复数）。 3.答案：read books; draw pictures 解析：“读书” 是 “read books”，“画画” 是 “draw pictures”，主语 “The pupils” 是复数，时态为一般现在时，动词用原形。 4.答案：making things; telling stories 解析：“做手工” 是“make things”，“讲故事” 是 “tell stories”，由 “are” 可知时态为现在进行时，动词变 - ing 形式（making/telling）。 5.答案：sit in; circle; sing songs 解析：“围成一圈” 是 “sit in a circle”，“唱歌” 是 “sing songs”，主语 “They” 是复数，时态为一般现在时，动词用原形；“to” 表目的，后接动词原形。 提升练 四、开放性试题。 1.答案：There are 5 pupils in each group on average. 解析：跨学科考查除法计算，总人数 20 人，分成 4 组，每组平均人数 = 20÷4=5，直接计算得出结果。 2.答案：Example: They can use clay. Because clay is easy to shape into different animal forms, and it’s safe for pupils. 解析：跨学科考查美术手工材料，材料可选 “cloth（布料）”“yarn（毛线）” 等，原因需体现 “易操作”“安全”“适合做动物” 等特点，合理即可。 3.答案：Example: I will talk about the number of pupils in my class first. Because it’s a basic fact and easy for my friend to know my class quickly. 解析：新情境考查书信开头内容，可从 “班级人数”“教室特点”“课堂活动” 等基础信息入手，原因需贴合 “便于朋友快速了解”，合理即可。 4.答案：Example: My classroom is not very big, but it’s very warm with many hand-drawn pictures. 解析：跨学科考查语文连词用法，需用 “but” 表转折，句子围绕 “班级 / 教室” 展开，前后内容形成对比（如 “小但温馨”“简单但有趣”），符合要求即可。 5.答案：Example: They can play “Pass the Parcel”. Players sit in a circle, pass a parcel while music plays. When the music stops, the one with the parcel opens a layer (层). 解析：跨学科考查体育游戏，游戏需适合 “围成圈玩”，如 “Musical Chairs（抢椅子）”，玩法描述清晰、符合逻辑即可。 6.答案：Example: They can take turns to clean the blackboard and sweep the floor every day. 解析：新情境考查班级管理，措施需贴合 “共同保持教室干净”，如 “分工擦黑板”“不乱扔垃圾”“定期整理书桌” 等，合理即可。 五、连词成句。 1.答案：There are twenty pupils in Lucy’s class. 解析：There be 句型结构为 “There + be 动词 + 主语 + 地点状语”，“twenty pupils” 是复数，be 动词用 “are”，按 “there be + 人数 + 地点” 的顺序组合。 2.答案：Her classroom is very big. 解析：主（Her classroom）+ 系（is）+ 表（very big），按 “主语 + be 动词 + 形容词短语” 的顺序组合，体现 “教室大” 的核心信息。 3.答案：Some pupils are making things in the photo. 解析：主（Some pupils）+ 谓（are making）+ 宾语（things）+ 地点状语（in the photo），按 “主语 + 现在进行时 + 动作 + 地点” 的顺序组合。 4.答案：They often sit in a circle to sing songs. 解析：主（They）+ 频率副词（often）+ 谓（sit）+ 方式状语（in a circle）+ 目的状语（to sing songs），按 “主语 + 频率副词 + 动作 + 方式 + 目的” 的顺序组合。 5.答案：Is it different from your class? 解析：一般疑问句结构为 “Be 动词（Is）+ 主语（it）+ 表语（different from your class）”，句末加问号，体现 “询问是否不同” 的核心意图。 六、单项选择。 1.答案：A 解析：跨学科考查减法计算，总人数 20 人，缺席 5 人，在场人数 = 20-5=15，故选 A。 2.答案：B 解析：问句询问 “学生在教室做什么”，B 选项 “读书和画画” 直接回答动作；A（有 20 名学生）回答人数，C（大且干净）描述教室特征，D（分组坐）描述坐姿，均不匹配问句，故选 B。 3.答案：C 解析：现在进行时结构为 “be + 动词 - ing”，“Some pupils” 和 “some（pupils）” 均为复数，be 动词均用 “are”；A、B、D 中 “is” 用于单数主语，语法错误，故选 C。 4.答案：B 解析：跨学科考查文化常识，“围成圈坐” 的优势是 “便于每个人交流（help everyone talk easily）”；A（让教室变乱）、C（让学生安静）、D（弄脏桌子）均为负面效果，与 “围成圈” 的目的不符，故选 B。 5.答案：A 解析：问句主语“Lucy’s class”是单数，答句需用“it”指代，肯定回答为 “Yes, it is.”，否定回答为“No, it isn’t.”；B、C 用“they”指代，语法错误；D “No, it is.”表述不对，故选 A。 6.答案：B 解析：新情境考查学习习惯，“保持书本干净（keep the books clean）”是阅读时的好习惯；A（大声交谈）、C（吃零食）、D（在书页上画画）均为不良习惯，故选 B。 七、根据情境回答问题。 1.答案：Example: Yes, we do. We often discuss math problems and make handcrafts together in groups. 解析：需先回答“是否分组坐”，再描述“一起做的事”，内容贴合课堂场景（如“讨论问题”“合作学习”）即可。 2.答案：Example: I will tell a story about a little rabbit. Because it’s interesting and all pupils like cute animals. 解析：需明确“要讲的故事”及“原因”，故事可选“童话”“寓言”等，原因贴合 “学生感兴趣”“内容积极” 即可。 3.答案：Example: Yes, it is. My class has 30 pupils, and we usually sit in rows instead of groups. But we also like playing games together. 解析：需先回答“是否不同”，再说明“不同点 / 相同点”，内容贴合班级实际（如人数、座位形式、活动），观点明确即可。 八、用所给单词的适当形式填空。 1.答案：are 解析：There be 句型遵循“就近原则”，主语“many books and pictures” 是复数，时态为一般现在时，be 动词用“are”。 2.答案：is writing 解析：由 “now” 可知，时态为现在进行时，结构为 “be + 动词 - ing”，主语 “Lucy” 是单数，be 动词用“is”，“write”变“writing”（去 e 加 - ing）。 3.答案：sat 解析：由“yesterday”可知，时态为一般过去时，动词 “sit” 的过去式为“sat”，“sit” 原形不符合过去时语境。 4.答案：Are 解析：问句主语 “twenty pupils” 是复数，助动词用 “Are”（句首首字母大写）；肯定回答中，be 动词与主语单复数一致，用“are”。 5.答案：are 解析：一般疑问句 “Are there...?”的肯定回答是 “Yes, there are.”，填 are。 拓展练 九、阅读短文，判断正（T）误（F） 1.答案：T 解析：短文中明确 “Lucy is in a small class with 20 pupils”，与原文一致。 2.答案：F 解析：短文中提到 “Her classroom is... big and bright”，“big and bright”（大且明亮）与 “small and dark”（小且昏暗）相反，与原文不符。 3.答案：F 解析：短文中提到 “Every morning, the pupils read books in the classroom”，“早上” 与 “afternoon（下午）” 时间不符，与原文不符。 4.答案：T 解析：短文中提到 “after lunch, they do activities in groups: some... some make paper animals”，与原文一致。 5.答案：T 解析：短文中提到 “On Fridays, they sit in a circle to play games or sing English songs”，与原文一致。 十、写作。 参考范文：Dear Lucy, There are 35 pupils in my class. We usually read storybooks in the morning and do group discussions in the afternoon. Sometimes we play“Pass the Parcel”in a circle after class. My class is very lively, and I feel happy to study with my classmates.Yours, Li Ming 解析：需包含“班级人数”“课堂活动”“对班级的感受”，语句通顺、符合书信格式（开头称呼、结尾署名）即可；若缺少任一要素，可酌情扣分（如未提“感受”扣 1 分），语法错误每处扣 0.5 分。 2 / 2 学科网（北京）股份有限公司 $
