It was foolish _______ him to refuse such a once-in-a-lifetime opportunity without any consideration. A. for B. of C. to D. with 答案：B 解析：形容词 foolish 描述的是“他”的性格特征（愚蠢）。在“It is + adj. + of sb. to do sth.”结构中，of 用于连接表示人物品质的形容词。该结构可转换为“He was foolish to refuse...”。 2.

The development of AI makes it possible _______ the early diagnosis of diseases. A. for doctors to achieve B. of doctors to achieve C. doctors achieving D. doctors to achieve 答案：A 解析：该句为“make + it + adj. + for sb. to do sth.”结构，it 是形式宾语，真正的宾语是复合不定式 for doctors to achieve。possible 描述事情的可能性，故用 for。 4.

A. for you to be B. of you being C. for you being D. of you to be 答案：A 解析：固定句型 There is no need for sb. to do sth. 意为“某人没必要做某事”。need 后常接 for sb. to do 作定语。 5. It was very considerate _______ you to turn off the lights before leaving the office. A. for B. that C. to D. of 答案：D 解析：considerate（体贴的）属于描述人物品质的形容词。根据“系表结构 + 不定式”规则，描述人的形容词后接 of sb. to do。 6. The challenge for the young engineer is _______ the complex system independently. A. for him to design B. of him designing C. for him designing D. of him to design 答案：A 解析：主语 The challenge 带有 for the young engineer 作定语，表语也应使用 for him to design 与主语结构保持平行。design 是不定式，需用 to do。 7.

A. for the team to process B. of the team processing C. for the team processing D. of the team to process 答案：A 解析：makes it easier 构成“动词+it+形容词”的形式宾语结构。easier 描述“处理数据”这件事，用 for sb. to do 表示动作的执行者。 8. It was unfair _______ the youngest child to take on all the household chores alone. A. of B. for C. to D. with 答案：B 解析：unfair（不公平的）描述“让最小的孩子独自承担家务”这一事情的性质，因此选用 for sb. to do 结构。若使用 of，通常指人本身的品质，此处不合语境。 9. The new regulation allows _______ their own working schedules. A. of employees to design B. for employees designing C. employees to design D. for employees to design 答案：C 解析：本题考查动词 allow 的用法。allow sb. to do sth. 是固定搭配，其中 sb. 作宾语，to do 作宾补，不涉及复合不定式（for sb. to do）作主语或宾语的情况。 10. What matters most in the competition is _______ the audience with creative ideas. A. for you to impress B. of you impressing C. for you impressing D. of you to impress 答案：A 解析：主语从句 What matters... 表示事物，表语应使用不定式 to do 说明内容。for you to impress 明确动作的执行者，与主语结构一致。 综合拓展练（测试时间：10分钟） 1. 2022年上海卷·翻译 你很好心，在百忙之中抽出时间来给我们当导游。（It） 答案：It is very kind of you to spare time from your busy schedule to be our guide. 解析：考查“It is + adj. + of sb. to do sth.”结构。形容词“kind”描述人的品质，因此用介词“of”引出逻辑主语“you”。不定式短语“to spare...”是真正的主语。 2. 2019年全国I卷·语法填空 Modern methods of tracking polar bear populations have been employed only since the mid-1980s, and it is difficult ______ (determine) the exact size of the current population. 答案：to determine 解析：考查“It is + adj. + (for sb.) to do sth.”结构。句意为“确定目前种群的确切规模是很困难的”。此处虽未出现“for sb.”，但仍是复合不定式作主语的结构，形容词“difficult”修饰不定式动作。 3. 2023年全国甲卷·语法填空 For thousands of years, ______ (be) honest has been considered one of the most important virtues. 答案：being / to be 解析：此处可用动名词“being”或不定式“to be”作主语。不定式作主语时常后置，但此处直接前置亦可。强调诚实这一品质，若用不定式则侧重于具体的行为准则。 4. 2020年江苏卷·单项选择 It is not a problem ______ we can win the battle; it’s just a matter of time. 答案：whether 解析：考查主语从句与不定式的区别。该题并非直接填动词形式，而是考查“It is + n./adj. + 从句”结构。原题空格后已有完整主谓结构，故此处应填连接词“whether”引导主语从句，而非不定式。可作为对比辨析题。 5. 2021年天津卷·单项选择 The student made ______ a rule to review what he had learned every day. 答案：it 解析：考查“make it + n. + to do”结构。句意为“这个学生把每天复习所学内容定为规矩”。“it”作形式宾语，真正的宾语是后面的不定式短语“to review...”。 6. 2016年上海卷·语法填空 I found it useless ______ (argue) with him about such a small matter. 答案：to argue / arguing 解析：考查“find it + adj. + to do/doing”。形容词“useless”表示性质，既可接动名词也可接不定式作真正宾语。此处不定式“to argue”或动名词“arguing”均可，但考点侧重在“it”作形式宾语承接复合不定式。 7. 2015年湖北卷·单项选择 The lawyer seldom wears anything other than a suit ______ the season. 答案：whatever 解析：此题虽主要考查状语从句，但后半句可引出“for sb. to do”的语境。实际教学中常类比复合不定式作定语，如“a suit for him to wear”，建议作为语境辅助题。 8. 2014年上海卷·语法填空 The most important thing for you ______ (remember) is to stay calm in the face of danger. 答案：to remember 解析：考查复合不定式作定语。“for you to remember”修饰主语“the most important thing”，不定式与被修饰词构成动宾关系（remember the thing），同时“for you”明确了逻辑主语。 9. 2018年北京卷·单项选择 It is important for people ______ (understand) the cultural differences. 答案：to understand 解析：考查“for”结构的复合不定式。形容词“important”描述事物性质（理解文化差异这件事很重要），因此用介词“for”引出逻辑主语“people”。 10. 2013年上海卷·语法填空 The room is comfortable ______ (live) in. 答案：to live 解析：考查复合不定式的主动表被动。在“主语 + be + adj. + to do”结构中，若主语是不定式动作的承受者（room被住），且形容词描述主语特征（comfortable），则用不定式主动形式表被动意义。可理解为“for people to live in”的省略。 6 / 7 学科网（北京）股份有限公司 $ 专题02 复合不定式（期中复习讲义） 内 容 导 航 考情透视·目标导航 透析期中考向，锚定备考重心 知识梳理·方法技巧 梳理核心脉络，扫除知识盲区 知识点01 知识点02 知识点03 知识点04 知识点05 知识点06 知识点07 知识点08 典例引领·即时检测 精析典型例题，强化解题能力 考场练兵·分层实战 阶梯实战演练，验收复习成效 考情透视·目标导航 核心考点 复习目标 考情规律 复合不定式（含连接词词） 掌握复合不定式构成、句法功能，能在复杂语境中准确运用 基础必考点，多以单选、语法填空形式考查，侧重作主语/宾语/表语 不定式与疑问词连用 理清“疑问词+to do”结构含义，区分不同疑问词搭配 高频考点，易与名词性从句结合设错，需注意成分完整度 不定式的逻辑主语 掌握逻辑主语构成，判断for/of的使用场景 易错点，常出现在形式主语结构、宾补相关题目中 知识梳理·方法技巧 知识点01 核心定义与结构 1. 本质 不定式 to do 本身没有语法主语，当需要明确“谁去做这个动作”时，就用 for/of + 宾语 引出逻辑主语，构成复合不定式，在句中可以作主语、宾语、表语、定语、状语等成分。 2. 两种核心结构 for sb. to do sth. 最通用的复合不定式结构 形容词描述事情的属性，不描述人的品质 important, necessary, difficult, easy, hard, possible, impossible, useful, dangerous, comfortable of sb. to do sth. 仅用于描述人的品质、性格的形容词 形容词描述人的特质，sb. 是形容词的逻辑主语 kind, nice, good, clever, wise, foolish, stupid, rude, polite, brave, honest 知识点02 for sb. to do 与 of sb. to do 区分黄金法则 1. 核心判断方法（100%准确） 在句子中，把 sb. 和形容词单独拿出来，造一个 sb. + be + 形容词 的句子： • ✅ 句子通顺 → 用 of（形容词修饰人） • ❌ 句子不通 → 用 for（形容词修饰事） 2. 实例验证 • 例1：It's kind **of** you to help me. 验证：You are kind.（通顺，kind修饰人）→ 用of • 例2：It's difficult **for** me to finish the work. 验证：I am difficult.（不通顺，difficult修饰“完成工作”这件事）→ 用for 知识点03 复合不定式在句中的成分 1. 作主语（最常考，对应讲义中形式主语结构） 结构：It + be + 形容词 + for/of sb. to do sth. • It 是形式主语，真正的主语是后面的复合不定式，避免句子头重脚轻。 2. 作宾语 结构：动词 + it + 形容词 + for/of sb. to do sth. • it 作形式宾语，真正宾语是复合不定式，常见动词：find, think, feel, make, consider等。 3. 作表语 结构：主语 + be + for/of sb. to do sth. 4. 作定语 结构：名词 + for sb. to do sth. • 用来修饰名词，说明名词的用途或相关动作。 5. 作状语 结构：for sb. to do sth. 作目的/结果状语 知识点04 复合不定式的时态与语态 1. 时态变化 for sb. to do（一般式） 动作与谓语同时发生，或在谓语之后 I hope for you to come tomorrow. for sb. to be doing（进行式） 动作与谓语同时发生，正在进行 He pretended for me to be working hard. for sb. to have done（完成式） 动作在谓语之前发生 I'm sorry for you to have missed the train. 2. 语态变化（被动式） 当逻辑主语是动作的承受者时，用 to be done： It is necessary **for the work to be finished** on time. 工作按时完成是必要的。 知识点05 高频易错点&避坑指南 1. 介词 for/of 后必须用宾格 • 错误：It's kind of he to help me. • 正确：It's kind of **him** to help me.（he → him，宾格） 2. 形式主语 It 不能省略 • 错误：Is difficult for me to learn math. • 正确：**It** is difficult for me to learn math. 3. 不要混淆复合不定式与宾语从句 • 同义转换：It is important that we should learn English. = It is important for us to learn English. 4. 特殊形容词的介词搭配（必记） • 只能用 of 的形容词：kind, nice, good, clever, wise, foolish, stupid, rude, polite, brave, honest, careless, careful • 只能用 for 的形容词：important, necessary, difficult, easy, hard, possible, impossible, useful, dangerous, comfortable, natural, common 典例引领·即时检测 典例01 （上海市七宝中学2024届高三上学期期中考试）对我们来说，在如此短的时间内完成这个项目几乎是不可能的。（汉译英） 即时检测 1. 对学生们来说，在两天之内记住500个单词是相当有挑战性的。 2. 对老年人来说，学会熟练使用智能手机并不容易。 易｜错｜点｜拨 1. 用 of 代替 for It is impossible of us… ✅ It is impossible for us…→ 形容事用 for，形容人品用 of。 2. 不用 it，直接用不定式开头 To finish the project is impossible… ✅ It is impossible to finish… 3. to 后用了 doing …to finishing the project ✅ …to finish the project 4. 漏写逻辑主语 for sb. 句子缺少“对我们/对他们”，意思不完整。 解｜题｜技｜巧 1. 开头必写 It is 2. 加形容词（possible/impossible/easy/hard/challenging） 3. 加 for sb.（对某人来说） 4. 加 to do 真正主语 5. 最后加时间/方式状语 典例02 （上海市复旦大学附属中学2023届高三下学期3月月考）The new policy makes it possible for small businesses _____ loans at lower interest rates.
