Unit 3 What’s the weather like? 专题02 语法提升·易错题专项训练 · 内容导航 · want to的用法 Let引导的祈使句 高频易错点、易错点提示、小练笔、答题点拨 易错精讲 want to的用法高频易错点01 · 人称变化：当主语是第三人称单数（he/she/it/ 单数名词等）时，“want” 要变为 “wants”，不定式部分 “to + 动词原形” 保持不变（例如：He wants to play football. 他想要踢足球。）。 · 语义延伸：除了接动词不定式表示 “想要做某事”，“want” 还可接名词表示 “想要某物”（如：I want an apple. 我想要一个苹果。），但接动作时必须用不定式结构。 例句：She wants to read a book. 他想要读一本书。 易错点提示 易错点 1：want后必须接 “to + 动词原形” 构成不定式结构，不能直接接动词原形 I want to see a movie. I want see a movie. 易错点 2：当主语是第三人称单数（he/she/it/ 单数名词等）时，want要变为wants She wants to see real snow. She want to see real snow. 小练笔 一、单项选择。 ( ) 1．I want ________ some bookmarks for my teachers.
