2026-2027学年九年级英语上册语法精讲精练（人教版新教材） Unit 2 Inspiring people 核心语法：It作形式主语 It is +adj. + for/of sb. to do sth. 语法精讲 一、It 作形式主语（重点：It is +adj. for/of sb. to do） 1. 基本概念 英语习惯避免 “头重脚轻”。 当动词不定式 (to do)、动名词、主语从句作主语很长时，把真正主语放到句子后面，用 it 放在句首占位，这个 it 就叫形式主语，it 本身没有词义，不能翻译。 句型 1：It is + 形容词 + for/of sb. to do sth（必考） 真正主语：to do sth. ① It is + adj. + for sb. to do sth 形容词描述这件事本身（难易、重要、危险），不能用来修饰人 常用形容词：important, difficult, easy, hard, necessary, dangerous, possible, useful 判断方法：不能转换成 sb. is adj. 例句： It is important for us to master English. （= To master English is important for us. 原始语序，极少使用） 翻译：对我们来说掌握英语很重要。 ❌ We are important.（不成立→用 for） ② It is + adj. + of sb. to do sth 形容词描述人的性格、品质，修饰人 常用形容词：kind, polite, rude, clever, stupid, honest, nice, generous 判断方法：可以转换成 sb. is adj. 例句： It’s kind of you to help me. = You are kind to help me.（成立→用 of） 翻译：你能帮我，你真好。 记忆口诀：能转 sb be adj，就用 of；只能形容事情，用 for。 句型 2：It is + 名词 + to do sth It is a good habit to get up early. 早起是个好习惯。 句型 3：It + seem/happen/appear + that…（it 形式主语，真正主语 that 从句） It seems that he is right. 似乎他是对的。 句型 4：It’s no use/no good doing sth（固定！动名词作真正主语） It’s no use crying over spilt milk. 覆水难收。 拓展：二、It 作形式宾语（高频考点，极易和形式主语混淆） 1. 概念 谓语动词后面本应跟上很长的宾语（to do /that 从句），为句子平衡，把长宾语后置，在动词和宾语补足语之间放一个 it 占位 → it 形式宾语。 核心标志： 主语 + 谓语动词 + it + 宾语补足语 + 真正宾语 (to do /that 从句) 标准结构： 主语 + find/think/believe/consider/make/feel + it + adj./n. + to do sth /that 从句 it：形式宾语（无含义，只占位） 例句讲解： I find it easy to learn swimming. 拆解： 主语：I 谓语：find it：形式宾语 easy：宾补 真正宾语：to learn swimming 直译：我发现学习游泳很简单。 原始语序（笨重，几乎不用）：I find to learn swimming easy. 常接形式宾语 it 的动词 find, think, feel, consider, make, believe, suppose ⚠️关键区分【形式主语 VS 形式宾语】（考试必考点） 三、快速辨别方法 It 作形式主语 句子开头就是 It → It + be + 形容词… It 作形式宾语 主语 + 实义动词 + it（it 出现在句子中部，be 动词不在 it 后面） 成对对比记忆 ✅形式主语：It is important to learn English. （学英语很重要） ✅形式宾语：I think it important to learn English. （我认为学英语很重要） 四、易错点总结 1.不要翻译 it！it 只是占位词，中文直接翻译后面真正主语 2. for/of 只出现在形式主语句型 It is +adj.，形式宾语没有 for/of 结构！ 3. make 用法特殊： We make it a rule to get up at seven.（形式宾语） It makes us happy to take exercise.（形式主语） 语法精练 一、单项选择题 1. It’s kind ____ you ____ help me with my lessons.
