Where 解析：询问地点用 Where，填 Where。 三、汉译英 1. Where is; behind; door 解析：“在哪里” 用 Where is，“在…… 后面” 是 behind，“门” 是 door。 2. Is; kitchen; isn't 解析：一般疑问句用 “Is he...?”，“厨房” 是 kitchen，否定回答用 isn't。 3. Is; under; bed; it is 解析：“猫” 是 the cat，“在…… 下面” 是 under，肯定回答用 it is。 4. isn't behind; living room 解析：“不在…… 后面” 是 isn't behind，“客厅” 是 living room。 5. Where is; on; chair 解析：“书包” 是 schoolbag，“在…… 上面” 是 on，“椅子” 是 chair。 提升练 四、连一连 答案 1 — A 2 — B 3 — D 4 — C 解析 1. 匹配 A：“Where's Danny?” 是询问 Danny 的位置，回应 “I don't know.” 表示不清楚对方所在处，符合对话开头的询问场景。 2. 匹配 B：“Is he in the kitchen?” 是询问 Danny 是否在厨房，回应 “No, he isn't in the kitchen.” 明确否定了他在厨房的可能，是位置排查的合理回应。 3. 匹配 D：“Is he under the bed?” 是询问 Danny 是否在床底，回应 “No, he isn't under the bed.” 明确否定了他在床底的可能，贴合位置确认的流程。 4. 匹配 C：“Look! Here he is.” 是发现 Danny 后的提示，回应 “Ha-ha! He's behind the door!” 点明了 Danny 的具体位置，完成了寻找对话的收尾。 五、连词成句 1. 答案：Where is Danny? 解析：特殊疑问句结构，“疑问词 + be 动词 + 主语”。 2. 答案：He is behind the door. 解析：按 “主语 + be 动词 + 介词短语” 顺序组合，符合核心句型。 3. 答案：Is he in the kitchen? 解析：一般疑问句结构，“be 动词 + 主语 + 介词短语”。 4. 答案：The cat is under the bed. 解析：按 “主语 + be 动词 + 介词短语” 顺序组合。 5. 答案：She isn't behind the sofa. 解析：按 “主语 + be 动词 + not + 介词短语” 顺序组合。 六、单项选择 1. 答案：B 解析：（数学）桌上 5 支铅笔 + 书后 3 支 = 8 支，故选 B。 2. 答案：A 解析：（科学）厨房需要保持干净，床下面和门后面不是重点清洁区域，故选 A。 3. 答案：B 解析：结合选项，“钢笔在书后面” 符合逻辑，in 表示在里面（书里放钢笔不常见），under 表示在下面（书下面不如 behind 贴合），故选 B。 4. 答案：B 解析：（生活）找到朋友的书包，直接告知位置，A 是询问，C 是确认归属，故选 B。 5. 答案：B 解析：后句 “在卧室” 表明不在客厅，否定回答用 No, she isn't，故选 B。 6. 答案：B 解析：my dog 是单数，否定用 isn't；后句 it 对应 is，故选 B。 七、根据情境回答问题 1. 答案示例：She's behind the door. Let's go and call her! 解析：回答老师的位置，提议去叫她，符合情境。 2. 答案示例：I can't find my pencil. Do you see it? Is it on the desk? 解析：向同桌求助，询问铅笔可能的位置，自然流畅。 3. 答案示例：Are you under the bed, little brother? I guess you're there! 解析：猜测弟弟的位置，语气亲切，贴合躲藏游戏情境。 八、用所给单词适当形式填空 1. 答案：is; is hiding 解析：Danny 是单数，对应 be 动词 is；“Look!” 提示现在进行时，hide 变 is hiding。 2. 答案：Is; is 解析：she 对应 be 动词 is，前后保持一致。 3. 答案：isn't; is 解析：my schoolbag 是单数，否定用 isn't；后句用 is 表肯定。 4. 答案：look; is 解析：let's 后接动词原形 look；he 对应 be 动词 is。 5. 答案：likes; under 解析：the cat 是三单，like 变 likes；“在床下面” 用介词 under。 拓展练 九、阅读短文，判断正 (T) 误 (F) 1. 答案：F 解析：原文 “my friends and I play a hiding game”，爱丽丝和朋友玩，不是家人，表述错误。 2. 答案：T 解析：原文 “We have three rooms: living room, bedroom and kitchen”，与题干一致。 3. 答案：F 解析：原文 “He isn't there”（厨房），汤姆不在厨房，表述错误。 4. 答案：T 解析：原文 “He's behind the bedroom door. Ha-ha! I find him”，与题干一致。 5. 答案：F 解析：原文 “She's under the sofa”，莉莉在沙发下面，不是床下面，表述错误。 6. 答案：T 解析：原文 “We have so much fun”，与题干一致。 十、【新情境・语文 + 社交】 答案 1.A 2. D 3. C 4. E 5. B 解析 1. 匹配 A：Mike 说找不到玩具车，接下来自然会询问玩具车的位置，“Where is it?”（它在哪里？）符合 “寻找物品” 的对话逻辑，是询问位置的核心句型。 2. 匹配 D：妈妈不知道玩具车的位置，回应 “I don't know. Let's look for it together.”（我不知道，我们一起找吧）既贴合实际场景，又用了 “Let’s + 动词原形” 的建议句型，符合三年级重点语法点。 3. 匹配 C：妈妈询问 “Is it in your bedroom?”（它在你的卧室里吗？），这是 be 动词引导的一般疑问句，否定回答需用 “No, it isn't.”，符合单元重点句型的答语规则。 4. 匹配 E：前面否定了 “在卧室”，妈妈继续猜测位置，“Is it under the chair in the living room?”（它在客厅的椅子下面吗？）既延续了 “确认位置” 的对话流程，又用到了重点介词 under，贴合单元方位表达主题。 5. 匹配 B：妈妈帮忙找到玩具车后，Mike 需要表达感谢，“Thank you so much, Mum!”（非常感谢你，妈妈！）是日常交际中的礼貌回应，与下文妈妈的 “You're welcome.” 形成完整互动。 多余选项解析 F 选项 “I like my toy car very much.”（我非常喜欢我的玩具车）与 “寻找玩具车” 的对话主题无关，没有合适的语境可以插入，因此为多余选项。 2 / 2 学科网（北京）股份有限公司 $
