(P24) 小学英语感叹句是表达喜怒哀乐等强烈感情的句子，句末通常用感叹号“!”。感叹句一般由what或how引导，具体结构如下： 1. 由 What 引导的感叹句结构： (1) What + a/an + 形容词 + 可数名词 + (主语 + 谓语)! 如：What a beautiful girl she is!她是多么漂亮的女孩啊！ (2) What + 形容词 + 可数名词复数 + (主语 + 谓语)! 如：What brave students! 多么勇敢的学生们啊！ (3) What + 形容词 + 不可数名词 + (主语 + 谓语)! 如：What cool weather it is! 多么凉爽的天气啊！ 2. 由 How 引导的感叹句结构： (1) How + 形容词 / 副词 (+ 主语 + 谓语)! 如：How beautiful the girl is! 多么漂亮的女孩啊！ (2) How + 主语 + 谓语！ 如：How time flies! 时光飞逝！ 易错点提示 1. how 与 what 引导的感叹句一般情况下可以相互转换，转换后意思不变。 如：What an interesting story it is!多么有趣的一个故事啊！= How interesting the story is!多么有趣的一个故事啊！ 2. What和how引导的感叹句的核心区别： · What 修饰名词（短语） · How 修饰形容词或副词 ❌ 错误：How a beautiful girl she is! ✅ 正确：What a beautiful girl she is! 3. 做题口诀： 去主谓，定末尾。名词 what，形副 how。a、an 出现要注意，形名相连用 what，形名相隔就用 how。 经典例题 The film is interesting. (改为感叹句) 点拨 答案：What an interesting film! / How interesting the film is! 【解析】句意：电影是有趣的。本题考查句型转换。感叹句的句型结构是 What+a/an + 形容词 + 主语 + 谓语！How + 形容词 / 副词 + 主语 + 谓语！interesting 是形容词，有趣的，元音音素开头，What 引导的感叹句可写成：What an interesting film! How 引导的感叹句可写成：How interesting the film is! 故答案为 What an interesting film! / How interesting the film is! 小练笔 02 一、单项选择。 ( ) 1．There are a lot of animals. ______ big zoo!
