核心语法归纳

核心语法一：名词性物主代词的独立用法与句型转换

概念：名词性物主代词（mine/yours/his/hers/theirs）可独立作主语、宾语或表语，后不接名词；形容词性物主代词（my/your/his/her/their）后必须接名词；两者可转换（例：This is her skirt. = This skirt is hers.）。

核心语法二：一般将来时（will/be going to）表天气与计划

概念：will + 动词原形 表客观预测（如天气），无人称变化；be going to + 动词原形 表主观计划；否定句在will后加not（=won’t），或在be后加not；一般疑问句将will/be提至句首。

核心语法三：季节、天气类短语的固定介词搭配

概念：季节前用介词 in（in spring/in winter）；具体天气的某一天用 on（on a rainy day）；时刻前用 at（at 3 o’clock）；描述“在……天气里做某事”用 in + 天气形容词（in sunny weather）。

核心语法四：特殊疑问词Why的问答逻辑与句式结构

概念：Why 用于提问原因，答语必须用 because 引导完整句子；句式结构为 Why + 一般疑问句？；主语为第三人称单数时，助动词用does（例：Why does she like autumn?）。

核心语法五：可数名词复数的不规则拓展变化

概念：除基础不规则变化（child→children/leaf→leaves）外，新增 snowman→snowmen；这类复数形式无固定规则，需结合单元主题场景记忆；注意区分单复数谓语搭配（a snowman is / two snowmen are）。

核心语法六：职业类名词的后缀规律与对应动词

概念：单元职业名词多含 -er/-or 后缀（worker/driver/firefighter/police officer）；部分名词可直接转换为动词（例：work→worker；drive→driver）；注意 police officer 为复合名词，复数直接加s。

核心语法七：There be句型的一般将来时结构

概念：表示“某地将会有某物”，结构为 There will be + 名词 + 地点 或 There is/are going to be + 名词 + 地点；遵循就近原则，be动词的形式由靠近的名词单复数决定。

核心语法八：祈使句表邀请的用法与回应

概念：单元中表邀请的祈使句结构为 Let’s + 动词原形 + 其他（例：Let’s make a snowman.）；肯定回应常用 Good idea! / Great!；否定回应常用 Sorry, I can’t.
