Coco, a little dog, goes to the park with its owner (主人), Tom. First, they hear a soft sound. "What is it?" Tom asks. Coco runs to a bush (灌木丛) and barks. Oh! It's a cat. The cat has small ears and big eyes. Tom says, "It's so cute! I like its big eyes." Then, they walk to a big tree. A small animal jumps from the tree. "Look! What's that?" Tom says. It's a squirrel. It has a big long tail. "Squirrels like eating nuts," Tom tells Coco. Coco looks at the squirrel and wags (摇) its tail. At last, they go near the pond (池塘). They see some small green animals. "Are these frogs?" Tom asks. Yes! They are frogs. Tom says, "Frogs eat bad bugs. They are helpful." Coco watches the frogs jump in the water. It's very happy. It's a great day for Coco. It sees many small animals and has fun in the park. 1.Who goes to the park with Coco? 2.What does the cat have? 3.What do squirrels like eating? 4.Where do Tom and Coco see frogs? 5.Why does Tom think frogs are helpful? 参考解析 基础练 一、将选项填入正确的表格中。 Cat squirrel frog A D B F C E 解析: 猫（Cat）的典型特征是 “有小耳朵（has small ears）” 和 “有大眼睛（has big eyes）”，对应 A、D； 松鼠（Squirrel）的特征是 “有长长的大尾巴（has big long tails）” 和 “喜欢吃坚果（likes eating nuts）”，对应 B、F； 青蛙（Frog）的特征是 “又小又绿（is small and green）” 和 “能跳得远（can jump far）”，对应 C、E 二、【新情境・生活运用】补全对话 1.B（What is it, Coco?） 解析：前文提到 “听到声音”，后文 Coco 跑去查看，此处应询问 “是什么东西”，故选 B。 2.D（Look! That's a cat!） 解析：后文描述 “有小耳朵和大眼睛”，符合猫的特征，此处应指出 “是一只猫”，故选 D。 3.A（Oh, they have big long tails!） 解析：前文确认 “是松鼠”，松鼠的典型特征是 “长长的大尾巴”，此处应描述该特征，故选 A。 4.E（Are those frogs?） 解析：后文回答 “是的，它们又小又绿”，符合青蛙的特征，此处应为一般疑问句 “是青蛙吗”，故选 E。 5.C（I like them. They eat bad bugs.） 解析：后文 “我也喜欢，它们帮助保持公园干净”，此处应表达 “喜欢青蛙，它们吃害虫”，故选 C。 三、事件排序 4 → 1 → 5 → 3 → 2 解析：事件顺序遵循 “去公园→听到声音找来源→看到猫→看到松鼠→看到青蛙” 的逻辑：“去公园” 是开端，排 1；“听到声音，Coco 想找出是什么” 是后续发展，排 2；“看到有小耳朵和大眼睛的猫” 是第一个发现的动物，排 3；“Coco 跑到树旁，看到松鼠” 是第二个发现的动物，排 4；“发现青蛙，觉得青蛙有用” 是最后发现的动物，排 5。 提升练 四、单项选择 1.A（do） 解析：问句主语是 “you”，谓语是实义动词 “like”，疑问句需借助助动词 “do”，故选 A。 2.A（have） 解析：主语 “the squirrels” 是复数，谓语动词用原形 “have”，“has” 用于单数主语，“is” 不符合 “有尾巴” 的语义，故选 A。 3.B（Are） 解析：后文回答 “Yes, they are”，问句需用 “Are” 引导一般疑问句，“What is” 和 “Is” 均用于单数主语，故选 B。 4.B（can） 解析：问句询问 “青蛙能做什么”，“can” 表示 “能、会”，符合语义；“like”（喜欢）和 “have”（有）不符合，故选 B。 5.A（It's） 解析：指代前文的 “the rabbit”（单数），需用 “it”，“它是白色的” 应为 “It's white”，“They're” 用于复数，“Its” 是形容词性物主代词 “它的”，故选 A。 五、【新情境・生活运用】用所给单词的正确形式填空 1.has 解析：主语 “the cat” 是单数，谓语动词 “have” 需用第三人称单数形式 “has”。 2.squirrels 解析：“those”（那些）后接可数名词复数，“squirrel” 的复数形式为 “squirrels”。 3.are 解析：主语 “those”（那些）是复数，be 动词需用 “are”。 4.like 解析：主语 “I” 是第一人称，谓语动词用原形 “like”。 5.is 解析：主语 “the mouse” 是单数，be 动词需用 “is”。 六、【新情境・生活运用】补全短文 1.C（It） 解析：指代前文的 “a rabbit”（单数），用 “it” 作主语，句首首字母大写，故选 C。 2.D（cute） 解析：“very” 后接形容词，“cute”（可爱的）符合描述兔子的语境，故选 D。 3.A（has） 解析：主语 “it”（单数），“有长耳朵” 需用 “has”，故选 A。 4.E（can） 解析：“能跳得高、跑得快” 用 “can” 表示 “能力”，故选 E。 5.B（like） 解析：主语 “I”，“喜欢它” 用 “like”，故选 B。 拓展练 七、【新情境・生活运用】阅读短文，回答问题 1.Coco's owner, Tom. 解析：根据短文中 “Coco, a little dog, goes to the park with its owner (主人), Tom.” 可知，和 Coco 一起去公园的是它的主人 Tom。 2.It has small ears and big eyes. 解析：根据短文中 “The cat has small ears and big eyes.” 可知，猫有小耳朵和大眼睛。 3.They like eating nuts. 解析：根据短文中 “‘Squirrels like eating nuts,’ Tom tells Coco.” 可知，松鼠喜欢吃坚果。 4.Near the pond. 解析：根据短文中 “At last, they go near the pond (池塘).
