They have long ears and short tails”，填 rabbits（兔子）。 2. ducks 解析：“How many ducks can you see?” 是核心句型，填 ducks（鸭子）。 3. eleven 解析：数词 “eleven（十一）” 对应课文语境，填 eleven。 4. thirteen 解析：“another duck” 表示 “又一只鸭子”，之前数到十二，现在是十三，填 thirteen。 5. short 解析：“short（短的）” 与 “long（长的）” 对应，描述兔子尾巴短，填 short。 三、汉译英 1. How many; eleven 解析：“多少只” 用 How many，“十一” 是 eleven。 2. Look at; flat 解析：“看” 是 Look at，“扁扁的” 是 flat。 3. long ears; short tails 解析：“长耳朵” 是 long ears，“短尾巴” 是 short tails（复数表泛指）。 4. Another; thirteen 解析：“又一只” 是 Another，“十三” 是 thirteen。 5. animals; count 解析：“动物” 是 animals，“数出” 是 count。 提升练 四、答案 1.A 2. B 3. B 4. A 5. A 6. B 解析 1. 答案：A解析：单元核心句型是 “How many + 动物 + can you see?”（你能看到多少只……？），A 选项直接对应 “询问兔子数量” 的情境；B 选项问 “这些兔子是什么”，C 选项问 “兔子在哪里”，均不涉及数量询问，故选 A。 2. 答案：B解析：单元中明确描述兔子的典型特征是 “长耳朵、短尾巴”，B 选项完全贴合这一核心特点；A 选项颠倒了耳朵和尾巴的长短，C 选项描述的是眼睛和嘴巴，未体现兔子的标志性特征，故选 B。 3. 答案：B解析：单元情境中 “又一只鸭子（another duck）” 出现后，原有 12 只鸭子的数量增加为 13 只，B 选项准确表达这一数量变化；A 选项是 12 只（未算新增的一只），C 选项是 11 只（数量错误），均不符合逻辑，故选 B。 4. 答案：A解析：问句核心是询问 “能看到多少只鸭子”，需直接回应具体数量，A 选项 “我能看到 13 只” 精准匹配要求；B 选项数量错误，C 选项未回应数量，仅说明动物种类，故选 A。 5. 答案：A解析：单元核心场景是 “数动物（count animals）”，A 选项 “让我们一起数动物吧” 贴合这一核心活动；B 选项询问 “是否喜欢动物”，C 选项询问 “动物总数”，均未体现 “邀请一起数” 的动作，故选 A。 6. 答案：B解析：单元中兔子的核心特征是 “长耳朵”，B 选项准确描述这一特点；A 选项说兔子有长尾巴，与单元知识点矛盾；C 选项混淆动物种类，鸭子的典型特征是扁嘴而非长耳朵，故选 B。 五、连词成句 1. 答案：How many rabbits can you see? 解析：特殊疑问句结构，“询问数量的疑问短语 + 名词 + 情态动词 + 主语 + 动词原形”。 2. 答案：Rabbits have long ears and short tails. 解析：按 “主语 + 谓语 + 并列宾语” 顺序组合，符合动物特征描述。 3. 答案：We have thirteen ducks now. 解析：按 “主语 + 谓语 + 宾语 + 时间状语” 顺序组合。 4. 答案：Look at those lovely ducks. 解析：按 “动词短语 + 定语 + 名词” 顺序组合。 5. 答案：I can see twelve ducks. 解析：按 “主语 + 情态动词 + 动词原形 + 宾语” 顺序组合。 六、单项选择 1. 答案：A 解析：（数学）鸭子 11 只 - 兔子 8 只 = 3 只，故选 A。 2. 答案：B 解析：（科学）兔子有长耳朵和短尾巴，鸭子有扁嘴，熊猫体型肥胖，故选 B。 3. 答案：C 解析：询问 “鸭子的数量” 用 How many，What 问事物，Who 问人，故选 C。 4. 答案：C 解析：（生活）看到可爱的兔子，应描述其特征并表达喜爱，A 表丑陋，B 是提问，均不符合，故选 C。 5. 答案：C 解析：问句询问能看到多少只兔子，C 边数边回答，符合情境，A、B 是一般疑问句回应，故选 C。 6. 答案：A 解析：twelve ducks 是复数，对应 be 动词 are；another duck 是单数，用 There's（There is 的缩写），故选 A。 七、根据情境回答问题 1. 答案示例：I can see twelve ducks. They're swimming in the lake. 解析：回答数量并补充鸭子的活动，符合情境。 2. 答案示例：You can prepare some fresh carrots and cabbage for the rabbits. Don't give them too much! 解析：告知喂养兔子的食物，提醒适量，自然实用。 3. 答案示例：Let's count together! One, two, three... It's easy to count clearly. 解析：主动提出一起数，帮助朋友，贴合情境。 八、用所给单词适当形式填空 1. 答案：are; are swimming 解析：thirteen ducks 是复数，对应 be 动词 are；“Look!” 提示现在进行时，swim 变 are swimming。 2. 答案：are; are 解析：rabbits 是复数，对应 be 动词 are，前后保持一致。 3. 答案：count; can 解析：can 后接动词原形 count；my brother 后用情态动词 can（无三单形式）。 4. 答案：have; them 解析：rabbits 是复数，用 have 原形；like 后接宾格 them。 5. 答案：look; see 解析：let's 后接动词原形，look 和 see 均用原形。 拓展练 九、阅读短文，判断正 (T) 误 (F) 1. 答案：F 解析：原文 “Today is Sunday”，杰克周日去公园，不是周六，表述错误。 2. 答案：T 解析：原文 “The rabbits are white. They have long ears and short tails”，与题干一致。 3. 答案：F 解析：原文 “there are ten rabbits”，他们看到十只兔子，不是十一，表述错误。 4. 答案：T 解析：原文 “The ducks are yellow. They swim in the lake”，与题干一致。 5. 答案：T 解析：原文 “Now there are thirteen ducks”，最后看到十三只鸭子，表述正确。 6. 答案：F 解析：原文 “I like ducks”，杰克喜欢鸭子，不是兔子，表述错误。 十、选词填空 1. A；B；C 2. E 3. D；F 4. G；H 解析 1. 答案：A；B；C解析：本句描述单元核心动物的特征，“rabbits（兔子）” 的典型特点是 “long ears（长耳朵）” 和 “short tails（短尾巴）”，这是本部分的核心认知内容，故依次填入 A、B、C。 2. 答案：E解析：本句是对兔子数量的计数，单元场景中数兔子的结果是 “eleven（十一）”，对应计数后的结果，故填入 E。 3. 答案：D；F解析：本句是对鸭子数量的初始计数，单元场景中先数出的鸭子数量是 “twelve（十二）”，“ducks（鸭子）” 是计数的对象，故依次填入 D、F。 4. 答案：G；H解析：单元场景中出现 “another（又一只）” 鸭子后，原有的 12 只鸭子数量增加为 “thirteen（十三）”，贴合数量变化的逻辑，故依次填入 G、H。 2 / 2 学科网（北京）股份有限公司 $
