人教版（2024）八年级下册期末复习（Units 1-8） 核心语法精讲精练 Unit 1 核心语法：动词不定式（to do） 一、基本定义与句式结构 动词不定式是初中最基础的非谓语动词，本质是不能单独作谓语的动词形式，无人称、单复数、时态变化。 ✅ 肯定式：to + 动词原形 ✅ 否定式：not to + 动词原形（高频改错考点） 二、六大句法功能（考试全覆盖） 不定式可充当除谓语外的所有句子成分，无需死记术语，结合例句理解即可： 1.作主语（表具体动作）：To read books is useful.（读书很有用） 简化句型：常用 It is + adj. + to do sth.（形式主语，考试最爱考） 2.作表语（解释主语内容）：My dream is to be a teacher.（我的梦想是成为一名老师） 3.作宾语（跟在特定动词后）：I decide to study hard.（我决定努力学习） 4.作宾补（补充说明宾语动作）：My mom asks me to get up early.（妈妈让我早起） 5.作定语（修饰名词，后置）：I have a lot of homework to do.（我有很多作业要做） 6.作目的状语（表动作目的，翻译“为了”）：I go to school to learn knowledge.（我上学是为了学知识） 三、高频考点：疑问词+to do 结构：what/how/where/when/which + to do 用法：等价于一个宾语从句，可直接替换，简化句子，常用于宾语、主语位置。 例句：I don’t know how to solve the problem. = I don’t know how I can solve the problem. 四、固定搭配分类（必背清单） 1.只接to do的动词：want, hope, plan, decide, refuse, try, wish 2.接sb. to do的动词：ask, tell, allow, invite, warn, encourage 3.省略to的不定式（黄金考点） 感官动词：see, hear, watch, feel, notice 使役动词：make, let, have 口诀：一感二听三看四让，主动省to，被动补to 五、易错辨析：see sb. do / doing •see sb. do sth.：看见动作全过程、经常性动作 •see sb. doing sth.：看见动作正在进行、瞬间片段 考点过关 ( )1．The group decided ________ some books and toys for the children in the poor mountain area.
