Unit 2 My classmates 单元语法考点 + 对点练习 班级：________ 姓名：________ 得分：________ 语法点 1 单元核心语法：help sb. (to) sth. 帮助某人（做）某事 一、语法详解 1. 两种标准结构（小学通用，to 可省略） ① help sb. do sth. ② help sb. to do sth. 含义：帮助某人做某事 2. 三单变形规则 主语为 he/she/ 人名等单数第三人称，动词 help → helps 例：Xiaopu helps teachers clean the blackboard. 3. 拓展搭配：help sb. with + 科目 / 物品名词（后不加动词） 例：She helps James with his Chinese. 二、教材原句剖析 1. Xiaopu always helps teachers clean the blackboard. 同义句：Xiaopu always helps teachers to clean the blackboard. 解析：主语 Xiaopu 是三单，动词用 helps，clean 用原形。 2. James often helps other students learn English. 解析：help 后接宾语 students，动词 learn 保持原形。 3. She often helps James with his Chinese. 解析：with 后接学科名词，不能使用动词。 三、易错点辨析 ❌ He helps me cleaning the room. ✅ He helps me clean /to clean the room. 错误：help 后只能接动词原形，不能加 - ing。 ❌ She help I with English. ✅ She helps me with English. 错误：①主语三单，help 变 helps；②help 后用人称宾格 me，不用主格 I。 ❌ I helps my mum cook. ✅ I help my mum cook. 错误：I 不是三单，动词用原形。 语法点 1 即时小练习 一、单项选择 ( )1.
